Owari no Seraph

He appears as a nondescript man with a business or gentleman-like bearing. Saito has short clean-cut black hair with bangs, where there is a parting on his centre right and again near the middle. This leaves his bangs uneven, with a conspicuous section of hair across his forehead. While the front section of his hair is the only part that can change depending on how it is swept, it is often to his left. Saito's hair is short enough to keep his ears visible, which are not pointed like other vampires due to bodily modifications. Although he actually has red eyes, Saito wears colored contacts over them to hide his vampirism, so they are a dull black. Vampire traits such as his fangs are also hidden.
Like other Thousand Night members, Saito wears a business suit that includes a collared white dress shirt of which the long sleeves can occasionally be seen at the end, and a relatively thin black tie. A black dress jacket is worn over this, which is fastened together by three buttons, and Saito also wears identically dark pants. Dark grey socks are also worn, in addition to laceless dark dress shoes.
Before physically altering his appearance, and dressing in a style consistent with the time period he is in, during the events of the past in Ancient Greece, Rigr's original appearance was that of a typical young-looking vampire with the physical age of someone in their late teens to early twenties. His hair was quite long and reached down to the back of his neck. Even when long on the sides, Rigr's pointed vampire ears were visible, where it is probable his eyes were also red at the time. His bangs reached over his eyebrows too. While Saito's hair is now black, it was light colored, his eyebrows included.
Clothing worn in the past was in keeping with what poorer members of society would have had. Although extravagant clothing was an option, it did not seem to have been worn casually. Basic tunics were a consistent clothing choice, where one was light in coloration. Across time, the tunics shared that Rigr had the top of them fastened with a string like material in a cross pattern. While Living in Romania, Rigr wore a dark medieval like tunic then too, with bracers on his arm. Additionally, light pants were over relatively dark boots. In a rare case where a sword was possessed, Rigr kept it on the left.

Pensive, Saito often contemplates matters at length, particularly when patiently awaiting developments. Speaking aloud to himself, Saito shares how he wishes the First would stop awakening so loudly as now others will get in his way. Giving thought to matters, more than once Saito comments on how topics such as what they are, and how many years has it been since he last saw someone, to be good questions. Often, Saito already knows the answer though. It was a good question in his view, where Saito could not say how strong he was, although clearly did know. This is a similar case when in pressuring situations. In no particular hurry, Saito will consider a situation and give thought to his options. In both events Saito is not in actuality overly bothered about potential obstacles, he will stick to what he has his mind on regardless.

“ It seems this was a trap meant for me after all. Now then... What to do? Should I leave, or should I allow it to play out? ” – Chapter 50 : "Brothers in Blood"

Calm in enacting plans as well, Saito acts at his own pace and is rarely perturbed. This remains the case when Saito is attacked; cut apart he is content to let it be observed how it is all for naught. Appearing joyful at being sliced by Guren, he would also be undaunted at being dismembered by the First. Speaking as he would normally, even in instances such as having his head detached, Saito also does not take into account how horrified others might be at his state. His severed head continues talking with Kimizuki, even with the threat of the First nearby.
A surprised expression is reserved when accused of trapping Krul, and when sensing the First's awakening. Genuine or not, Saito does not hide such an expression where often he conceals his true feelings under a warm smile. In response to surprises, Saito focuses on his objective at hand and attempts to avoid them. With Urd arriving in Japan with a host of vampire nobles, Saito fled rather than engage with them. Where it was a trap set by Ferid, and seeing him again after time, Saito still headed to where his goal concerned him rather than enact punishment, or speak further.
Having a pleasant demeanor, Saito is exceptionally nice to both followers, and those hostile to him. Although vampires, generally speaking, regard humans as livestock at best, and allow ranks to influence their views of other vampires, Saito does not look down on either in the same manner. Where the world has been divided between human versus vampire factions, Saito employs both human and vampire forces in his Hyakuya Sect, all acting under one banner, the only major organization to do so.
For those of interest, Saito treats Mika gently and gives him money for ice cream when out walking with him in the summer of 2012. However, where Yu was acting temperamental, Saito opted to drag to the orphanage on Christmas Day. Blunt, Saito tells Yu that his home went up in flames. Further, that Yu was so hated by his own parents that they tried to kill him. Despite that, Saito mentions that in the Hyakuya Orphanage , everyone there was just as unwanted as him, therefore he would have a big, new family. In at least trying to get on someone's level, Saito resorted to different methods when interacting with others.
In forming alliances or engaging with those he can have a use for, Saito attempts discourse rather than ruling by force in such cases. While he indicated an idea that he was superior to Urd as he was still a vampire where he was not, Saito addressed how they were both brothers sharing the blood of the First, and attempted to make use of that connection to persuade him that they should stop interfering with one another's plans. It was a similar happening with Guren, where Saito spoke to him first of their shared enemy in the Hīragi Family . Also in both cases, Saito opted to fall back rather than fight, where dialogue would be successful later in having them work together.
For his position and what he is working towards, Saito is not particularly violent, especially when compared to others. Rational, when attacking it is done swiftly and effectively. Assaults may also be tests to induce changes in others. Missile strikes he orders on a number of aircraft successfully hinder other vampire progenitors' progress for a time, done not out of malice but to ensure he could act first. It is an attitude that can help him taking into account what he may be after, but does not seem like one that would make the best use of the capabilities he has. Nevertheless, it does not stop Saito from being proficient with the many strong powers at his disposal, a non-violent streak does not prevent him from using chains and spells decisively when he wants.
A rare case of a vampire embracing human based creations, Saito also employs the use of spellcraft. Not being dismissive of something based on who made it, Saito neither disregards items that are strong, even when they are not as powerful as his abilities as a second progenitor. Still helpful to him either way, Saito uses spell tags and other magical capabilities for supportive measures. Analytical enough to consider why vampires would not use notably helpful contraptions, Saito is sure to exploit these weaknesses himself for his own advantage.

“ It was an illusion. One of the kind humans can create. Vampires have a bad habit of looking down their noses at humans... ...Making it all too easy for them to fall for human tricks. ” –Explaining a spell tag created version of himself that appeared to break out a prison, and fight other progenitors. Chapter 106 , "I Am Your...", page 15

Where many keep their secrets, Saito is forthcoming in providing sensitive details that only a select few would know. In attempts to bring Guren over to his side, Saito detailed the very seismic event of how the world would end. Information Saito has is used to gain favor with others. Stating he was aware of why the First took other third progenitors but not Lest Karr, he offers these details, and made it all the more enticing by emphasizing the urgency.

“ Let me out and I'll tell you. Urd will surely kill me when he comes. Then the secret you want to know so badly will be forever out of reach. ” –Framing it as a last chance to persuade Lest Karr to free him. Chapter 105 : "Saito and Urd", page 33

It is not the same story when it comes to sharing details about himself. Calculating, Saito goes to great extents to hide his true strength and identity to new people. While facing Guren in First Shibuya , Saito would not reveal his real name at first which done little to benefit him given he was seen as an assassin. It is difficult to ascertain his true nature. This is not helped when he professes things that may not be the case. Suspected of being behind a plot to trap Krul, when accused of having Ferid serve as his lackey, Saito unconvincingly claims that he has no idea what she was talking about, even though it really was the case he was not involved with Ferid's plan.
On account of their very being, where vampires generally do not express emotions aside from a desire for blood, feelings shown such as amusement is considered abnormal enough to deem one eccentric. Even considering normal standards of humor, Saito not only displays a humorous streak, but one that can be alarming. This is all the more disquieting when he exhibits it during times of danger to himself.

“ Oh, this? I woke up one morning and it was like this. Isn't that strange? Ha ha! ” –Answering the First on what happened to his head, when it is floating in the air while connected to his body by a chain. Chapter 81 : "Fallen Wings", page 14

It may not be intentional or may be so natural to him that he does it without anyone picking up on it, yet Saito could have a surreal sense of humor, as illustrated with mannerisms and certain behavior. Speaking as his body is being re-attached via chains, Saito also decides to hang upside down from the ceiling. Self-deprecating, Saito spoke of doubting his own capabilities of being able to capture the First and added how he felt he would fail. Feigning ignorance at decidedly not regular occurrences may as well be a personal hobby for him. Regarding the chains in his body, Saito speaks how he just woke up one morning and it was like that. Rhetorically asking whether that is not strange, Saito then laughs to himself as he enjoys quite the grand time.
His sense of humor also supplements one of Saito's most distinguishing traits, namely having the deceptive habit of saying the opposite of how he feels on the inside. Although upfront in telling the First he was restraining him, Saito then professed that he was not at all confident and had the feeling that it would fail utterly. A pretense where his words did not reflect his well-prepared actions, Saito seemed sure his aim was feasible, which it likely was given his challenge against the First.
Reverse psychology is used effectively on targets. It functions all the better when Saito, through intuition or background knowledge, has a good grasp of how others may react. A contented guise accompanied with his words can induce combatants into attacking, where Saito awaits like a claw-trap, only one far more lethal to a greater number of beings.

“ Yes, I would die quite dead. Please don't cut- ” –Pretending that cutting the chain connecting his head and body would result in his death, knowing full well that the chain would be cut, to result in a huge mass of chains springing out into the First. Chapter 81 : "Fallen Wings", page 15

Maintaining a facade even with it clear his actions are a ruse, Saito continues to downplay what he has prepared. Armed with something monstrous that even Shikama Doji seems wary of, Saito is afraid to say how the beasts of the apocalypse he has at hand are all smoke and mirrors. A deeply misleading claim where they are more than capable of crashing into the First's scythes. Keeping an eye on how the battle is going, Saito remarks whether the First just became stronger, and thrilled, he orders a counter-measure at the right time. Being duplicitous is helpful to Saito, but equally as prominent is that he derives happiness from it. In all such situations, Saito had the greater retaliation for what was sent at him. Further, the conflict was going his way.

“ Uh-oh! Don't tell me you just got even more powerful. ” –Drily commenting on the First's strength, before activating the full curse system when the First fights how Saitō wants. " Nativity of a Princess ", page 8

An appearance of being anxious is shown when Guren threatens to overpower and kill him, this was despite the fact he is actually far stronger. Another display may have been one of slight exasperation when the attack on the school goes off schedule. Also commenting on his odds at coming across Guren and Shinya there, it is that he intentionally sought them out.
In times of what may be genuine trouble, Saito reacts with worry. Prepared to double-cross Guren in the middle of an intense fight with the First, he saw the chance to drain power to supplement his own. Betrayed in turn, Saito's expression of shock when he was stabbed with a Sinful Key by Ferid seemed real. Secluding himself in an alleyway, in the aftermath of an assault that left his entire lower torso missing, Saito weakly considered what further parts of his plot could be enacted. Although Ferid seemed a threat upon his return with the sinful key, Saito was fast enough to attack with his chains, however he still acted to restrain rather than destroy this menace.
Not as concerned with someone who had successfully ambushed him and blown half his body off with a sinful key, where the injury was not regenerating as fast, Saito anticipated greater problems incoming. More conscious of Urd's arrival, planning ahead, Saito's thoughts in a soon to be even more dire situation involved having his body recover. Not being weighed down by pride is a great asset for him, in welcoming Urd's lifeline of an offer of help, after accepting, Saito found an expected problem dealing with the threat of Ferid on his behalf.
Fear does not impact Saito, even when perhaps it should. Having his severed body investigated by Ky Luc he matched his curiosity with an interest of his own. Unfazed at the comment that all of his bones should be broken, Saito remained undaunted despite his precarious state. Escaping, yet being caught again did not result in dread, neither was anything incapacitating felt to his emotional state when confined to a magically imbued prison that was formed to stop stronger beings such as him from escaping. Even with the presentiment that Urd would kill him, Saito was not afraid of that, rather it provided an opportunity for him to only claim to be scared.

“ Oh no. I'm scared out of my mind. Please don't pick on me. ” –With Ky Luc picking up that Saitō looks in total control he expresses otherwise, which greatly provokes Ky Luc. Chapter 105 "Saito and Urd", page 7

His hunch on the mark, where Saito's meek allegations that he was not as strong as reported, and particularly the submission that he was frightened could have worked was in inducing Ky Luc to attack him, and so afford the chance of damaging his prison from the outside, for him to escape. While such a hypothetical occurrence did not come to pass on account of Lest Karr's interference, Saito still riled him with offers of news on his background. Ultimately, although Saito knew where to metaphorically stick pins, yet where his provocations did not yield results, he still seemed to delight in them anyway.
A sense of coldness, outwardly indistinguishable from sereneness is maintained when taking actions that correspond with being frustrated, or murderous. Seemingly at ease in a prison, Saito suddenly crushes the arm rest with his hand. Informed that this was disturbing other vampires , Saito claimed that he was bored before deciding that maybe he could pass the time by killing every single one of them. Adding that may be fun, Saito certainly does not miss the chance to deliver a candid response to those who think they are done should they mess up.

“ Actually... ...I'll destroy you all even if you don't mess up. ” –Answering Lest Karr's concerns that if they mess up here he might destroy them all. Chapter 106 , "I Am Your...", page 2

A detached attitude is had towards others, seemingly on a whim. Without a word, Saito slaughters the scientists in the room with Mirai , all the while with a contented smile on his face. Although the action helped her, Saito opted to refer to Mirai as "it". With what his Hyakuya Sect is involved in, Saito is not above human experimentation.
His true objective is unclear, even to those such as Mahiru who he works with. Someone as close as Basteya who was counted on in a plan involving restraining the First only made reference to Rigr being behind it all. Where it is felt to be certain is that Saito is invested in the Seraph of the End project. He is the one who invites Mahiru to the Thousand Nights, which they both betray later on. Although Saito convinces Mahiru to become a vampire, he refuses to turn her himself.
One clear part of his motive seems to be his desire to be acknowledged and "seen" by his "Father" ( Sika Madu ). This seems to be one of his foremost goals and a principal drive behind all of his actions. Although never outright stated, this obsessive desire to be noticed by his "Father", is also one of the main reasons for him changing his name and appearance to that of a Japanese name and a more Asian appearance due to his "father's" preference for the country. Later during his destructive battle against the First, he was shown to have become excited and giddy at the prospect of his "Father" finally beginning to "notice" him.
Resentment can manifest in different ways, before completely reversing in some cases. After witnessing the experiences that befell Sika Madu from other angels, Saito's anger changed from resenting the First, to becoming irate that he had been shouldering a heavy burden all by himself and without telling anyone. In such rare cases where Saito does express anger, he can quell such feelings upon a change in perspective.
Critically considering matters, Saito gives some thought to whether memories he is accessing are true. After witnessing angel souls flying into humans, that he is potentially an angel is something Saito readily accepts however. It was peculiar for Saito to shed tears for two reasons, both on account of his temperament and that he is a vampire which generally are unable to feel as much. Saito found that he was crying after learning about Sika Madu's background when thinking whether he still memories from being an angel.

“ ?! I don't remember any of this, but... ...I'm crying. Is that...? ...Do I still have my angel memories somewhere...? ” –Tearful having witnessed angel related memories where he accepts he is one. Chapter 130 : "The First Vampire" Page 10

Compared to other vampires especially, Saito pays attention to specific humans. In understanding their motives, Saito also concludes to himself that Guren and Mahiru were behind the First's disappearance. Certainly unlike other vampires, Saito is prepared to hear out those such as Yu for details on where the First went. Saito is attentive to specifics.

“ Now this is odd. You told us before that it was another human. One who's your enemy who had devoured the First. ” –Attentive to details that humans have mentioned, in contrast to other vampires. Chapter 140 : "The World I Want" Page 7


Owari no Seraph

He has the appearance of a young man with notably tanned skin compared to other characters. Being a vampire Urd has the characteristic pointed fangs. His shiny, golden-blond hair is styled in a neat manner. Parted over his forehead so his vampire-red eyes are visible, Urd has a section of hair in the middle, and on either side of his head in-front of his vampire pointed ears. Upon his left ear, he has a golden adornment consisting of two clasps upon the upper and lower shells, which are connected by a thin chain. From the lower cuff hangs a tapered charm. Based on them not being seen in the past, Urd's ear piercings are more recent.
His attire consists of a dark sleeveless vest featuring six buttons. This is worn over a white collared dress shirt of which the long-sleeves can be viewed. The pants are the same color as his vest. Urd occasionally dons a formal-styled mackintosh with a high collar. He wears black gloves and a decorated neck tie. In the past Urd wore clothing more in keeping with the time period. A white tunic was worn loose over Urd's frame, that had a black belt around his waist. At a later point in time, a similar tunic option was chosen. Again it featured a black belt, where a long-sleeved shirt was worn underneath. Urd's dark colored sword sheath has consistently been held on his left hip.

Serious in virtually all matters, Urd is shown to possess a cool, nonchalant attitude. He claims to dislike unnecessary fuss, as displayed in past memories of him alongside Rigr. Similarly upon finding Lest Karr nearby Urd wondered what he was doing here. Speaking directly he orders Ferid to reach the point when there are troubling circumstances at hand. Growing tired of Ferid speaking at a later point, Urd commands Lest Karr to silence him. Sentencing them swiftly without a second thought, Urd spoke how Krul and Ferid had best have an interesting story to tell once their sunlight exposure torture was over.
He also displays a superior side as he constantly reprimands Lest about his words and place and refers to Ferid and Crowley as 'lesser vampires'. In fighting Crowley he took the moment to state how it would be easy to break through his sword. He also seems to believe that vampirism is a revolution for humans, as shown by his interaction with the recently turned Ashera.

“ Do not fear. As of now, you have shed your humanity. You have been permitted to become a superior being that surpasses humans. ” –Alleviating Ashera's concerns after he is transformed into a vampire and his view on their state. Chapter 79 : "Eternal Hell", page 23

Having a very strong sense of responsibility is useful being the King of Russia. Although vampires have divided themselves up into factions and generally keep to their own devices, Urd does not dismiss foreign affairs as outside his concern. Not only would he travel with an army of nobles, Urd personally sets out to reclaim a city lost to human forces.
Urd appears to be a strict follower of the rules laid out for the vampires. He has no initiative to stray from his path as a second progenitor, even when Saitō states the position to be boring and foolish.
Though harsh, Urd is also shown to possess fair judgement, displaying a quite reasonable and even somewhat merciful side when dealing with events that do not require serious handling and apparently being more inclined to non-lethal punishments instead of just instantly killing guilty vampires. He withholds blame towards Lest for being unable to stop Saitō, acknowledging his weaker position as a Third Progenitor. Even though he dislikes Ferid, he does not let that get in the way of his reasoning side, showing him some mercy by ordering Lest to return Ferid's heart to stop him from becoming a demon and later on giving Ferid and Crowley a chance of survival, presenting them with the option of surrender and facing judgement from the Progenitor Council, rather than death by him (he only resorts to attacking them after Ferid's challenge).
Unlike most other vampires, Urd is shown to consider the wellbeing of the humans under his rule. Human children in Russia are allowed to wear normal clothes and run around with no restriction, where they also appear quite happy. [3] Likewise, Urd values humans more than others of his kind, and stated to often be found observing humans for entertainment purposes. Watching the humans perform ballet is also an indication of an interest Urd has that does not concern blood, where that often occupies a vampire's focus. [4]
Although fast to respond, and acting decisively in the moment, Urd has an indifference for follow-up actions. After rapidly engaging Saito, there was no inclination to pursue him. Sentencing Krul and Ferid was done on the spot and carried out. When Ferid was freed, Urd seemingly thought nothing on this, neither for the group who were capable of freeing him. For all his willingness to kill Ferid when he found him in Shibuya, he allowed him to escape. Despite vowing to destroy the city of Shibuya, as with other scenarios Urd gives it no further thought once another matter arises. Promptly making up his mind that eliminating Yu was the safest and easiest option given that the First was targeted for attempting resurrection, Urd instantly sets about trying to eliminate him. His attempt thwarted, Urd returns to silently observing, all his intent to administer swift action gone.


Owari no Seraph

He appears as an androgynous adolescent male with long dark purple hair that goes beyond his feet, while his bangs cover his left eye. As a demon, an entity that was once a vampire, Asuramaru has red eyes, fangs, and pointed ears. When the curse restraint loosens, his horns grow larger and the nails on his hands and feet become claw like.
For clothing he wears a sleeveless open-back dress including a collar with gold beads covering his throat. The chest piece is black while the rest of the dress is white, and the gown splits open at his outer thighs which would free his legs for movement. The black sleeves Asuramaru wears are separated from the gown that reach his mid-upper arms and come down to his middle fingers, where each sleeve is attached to a ring. He is barefoot. On Asuramaru's head is a headband formed of two parallel golden strips that match the horns piercing through his hair from the edge of his hairline.
In appearance and clothing Asuramaru shares some resemblance with his sister, Krul, such as the horns with the exception they are white. Furthermore, the rings on his sleeves with only two of them being white, then both of them have long hair, where Asuramaru's hair is unsteady.
Occupying in his own plane of existence, his hair and clothes freely wave of their own accord. As Asuramaru exists as a mental concept, he can appear as anyone within Yu's memories he chooses. He often takes the forms of the twelve-year-old Mikaela Hyakuya as well as Akane Hyakuya and the other Hyakuya orphans when using them to guilt Yu. He can display Yu's parents in attempts to flare up traumas. Asuramaru chooses his forms depending on what he believes will be best for breaking his host's will. His initial form was a shadowy towering mass with two eyes discernible. This substance could also be used to form impaling spikes.
One thousand years ago, prior to turning into a demon, as a human, Asuramaru had blue eyes and tied his relatively long, dark colored hair in a ponytail style. He wore a black shirt underneath with white sleeves. The outer line of his shirt is colored thin white, and he wore black trousers held with a white belt. Asuramaru has bandages wrapped around both his legs from his feet to his knees and wore sandals.

With them seemingly magically induced to think and behave in a certain manner, Asuramaru is a blood-thirsty demon who enjoys feeding off humans. Sharing a vampire's thirst for blood, he delights in drinking Yu's blood and goes into a giddy high after being fed it for the first time via the sword. In other cases, Asuramaru will settle for strong human desires to feed off of. As a possession-type demon, he is described as particularly nasty and aggressive. Bound by rules, Asuramaru is forthright in explaining them, as he has to under the bindings of chains. He is similarly upfront in explaining what he intends to do, what he wants, before engaging in violence for possession purposes.
Like all demons, he is manipulative and uses nightmares to erode a person's constitution for the purposes of possessing them, in order to take over his host's body. When he first formed his contract with Yu, he interrupts his dreams every night in a sustained effort to wear him down. After all, the only reason he allows Yu to borrow his power is for the future opportunity to take over his body to act in the physical world. After Yu loosens the curse on him and the two battle for dominance, Asuramaru eventually relents to Yu's compassion. Submitting to him, Asuramaru ceases the nightmares he was inflicting on Yu.
Able to recognize traits that could be regarded as bad, but hardly considering his own, Asuramaru thinks of humans as vile, greedy creatures who are even worse than vampires and demons. He regards them as taboo-breakers who will destroy the world. His unfavorable views has him think no better of seraphs , where Asuramaru considers them to be disgusting, yet he is conscious of what they can do. Despite holding seraphs in contempt, he helped Yu with his aim to help the 6th trumpet after being convinced by him. With time and pleasant experiences, Asuramaru becomes more considerate, and curious. Although he does change his temperament in response to Yu's treatment of him, Asuramaru does remind him trusting a demon is a mistake.
In wanting to know more about Yu's past, he would delve into memories in the interests of learning about them. While knowing Yu's most intimate and personal feelings, they are seen as tools for possession, yet he will reveal certain information. Sharing that there was a part of Yu that was not human, Asuramaru also disclosed that memories had been tampered with. He also points out that a different family member has come to visit Yu, in reference to Mika. Although he is fully aware of Yu going insane on the battlefield, Asuramaru does not divulge such vital secrets to his host. Generally, Yu is left to figure out matters on his own, yet Asuramaru is interested in what could challenge his control of a host, whether it be human experimentation, or the presence of a seraph. If anything, he is a trusted enemy (he is clear in what his intent is) rather than a friend or ally.
Asuramaru becomes greatly annoyed when someone else disrupts his mind sphere, as Shikama Dōji did. [5] Pitying who he saw, Asuramaru then moved to attack the newcomer. Solicitude was shown for his host Yu, as when he tried to get him out of Shikama Dōji's grasp. Asuramaru will help the human he is attempting to possess over a hostile non-human. [6] Not bothered with being used as a sword, Asuramaru will use that as a means to an end. Whether in attacking foes or being turned into one to be rescued from Shikama Dōji's grasp. All that matters in that Asuramaru gets what he desires.
In his days as a human one thousand years ago, Asuramaru enjoyed viewing the blue sky, and gazing directly at the sun. [7] [8] He regrets leaving his sister behind and becoming a demon. [9] Asuramaru also cares for his family. Unlike his sister, Ashera did not share her enthusiasm for being thankful for everything they had since he was from a noble family. [10] [11]
Finding himself enslaved, Asuramaru's thoughts turned to his sister's wellbeing and saving her. Being purchased, Asuramaru had questions he asked a past Yu, and addressed Sika Madu as master to not make a bad situation worse. Finding the past Yu's mannerisms odd, Ashera remained vigilant and observed his circumstances. Perspicacious, he questioned Yu whether Sika Madu was bringing children to his bed chamber. Dispirited with the revelation this was the case, Ashera sat in silence, unenthusiastic about playing with the toys offered to him by the past Yu. Resolving to stay strong since Krul was still out there, being determined is a trait that appears when matters are dire.

“ I can't afford to lose. I'm not going to lose here! ” –Dismembered, Ashera remains determined. Chapter 118 : "I Hear Voices" page 8

Appearing petrified at the sight of a murderous seraph Yu, in noting the time he died, Ashera was surprised to wake as a vampire. Again thinking in the moment, he considered his new greatly enhanced senses and became aware of a thirst for blood. Rather than interacting with Rigr Stafford and Urd Geales , and paying no mind to the claims of now being a superior being, Ashera sought out Sika Madu. Surprised, he attempted to make sense of the scenario of experimentation before him. Feeling uncomfortable at the thought of trespassing in a prohibited room where Michaela was kept, Ashera was also against Noya murdering a past Yu. The sentiment did not diminish, Ashera remained disgusted with the murderous act and no regard for what was judged a renewable form of life. Bringing the lifeless body of a past Yu and telling Sika Madu he was responsible for it, Ashera did not try and hide what happened, and covered for others. When Ashera found out that Noya kept murdering the Yu clones who kept annoying him. Ashera became more disgusted at this, to the point he commented it make him sick.
After regaining his memories as a human in the present time, Asuramaru's personality changes as he starts to become more merciful and even nicer in his demon-nature side. Even though he had the genuine opportunity to possess Yu's body, he withheld doing so, instead opting to tell Yu about Mika's last words. Asuramaru consoles him with words how hard life can be hard when Yu cried as well. Speaking at length to put matters into perspective, Asuramaru was patient in being there as a support for someone. Citing Mika's sacrifice to give him a reason to live, Asuramaru advised Yu to simply not throw his life away. With Krul concerned, he appeared before her to say their course of action was okay.
Even with his human memories returned resulting in a drastic turnaround in his personality, at being contacted by Shikama Dōji to capture Mikaela he entered a particularly vicious state that was out of character even compared to when he was a mindless demon. An eagerness to fight a far stronger foe than him was a pretense that masked an even greater excitement to reach Mika and Yu in order to eat them. Asuramaru relished the focus placed on him by Demon Mika since it kept him distracted from other demons. His satisfaction that he had won was eclipsed by the savagery Asuramaru displayed when articulating how he was going to not only eat Yu and Mika's whole family, but also rip their hearts to shreds.
Unsure of whether to let Yu devour him or resist, Asuramaru seeks the First's guidance even when under attack. Resolving to fight, upon getting his answer that he should let Yu consume him, Asuramaru is deeply affected at the idea of being thrown away despite working with him for so long. Regaining his resolve relatively quick, Asuramaru means to fight to defend Krul even though his opponent is much stronger. Making use of the power he can drain to then swiftly restore his damaged body, during combat Asuramaru exploits the advantages he gains.

“ It looks like I can win. Do you know why your neck isn't healing? Because Mikaela is refusing to do it. He wants you to lose. ” –Employing's psychological warfare against Yu in an attempt to prevail in a fight. Chapter 117 : "Of Monsters and Demons" page 36


Owari no Seraph

Krul is a young girl, she is noted to have a petite figure, she is considered to be extremely pretty, even by vampire standards. She has calf-length rosy pink hair, partially done up into two pigtails held by black hairpieces of which the design appears inspired by bat wings. The black headdress is connected by a black headband, and she also has what appear to be short black horns at either temple. Krul has large, sharp, slightly slanted eyes that are red, as with all vampires, along with fangs and pointed ears.
She is occasionally seen with a one-eyed bat familiar, by the name of Arukanu , upon her shoulder. The bat is about the size of her fist and has a large eye in the center of its face. It has a pair of small horns on top of its head and has a thin devil-like tail about twice the length of its body. It has small bat wings and minuscule feet.

In the past as a human

Before she turned into a vampire, Krul's eyes were blue like her brother's. She wore her long pink hair with one of her bangs tied into a long single braid. This was frequently decorated it with flowers. Krul's attire consisted of an ancient Greek styled chiton, with a simple ribbon tied to her waist, and sandals tied with long ribbons to her feet.
Her attire as a vampire consists of a short black, frilly style dress with a layer of white ruffles over black ruffles of the skirt. The top has a raindrop shape opening on her chest, and the straps of the top cross before reaching her neck on either side. The top has an open back with two x-shaped crossing stitches tightening it at her waist. A strip of pink heads down either side at the front of her top and ends at bows above the ruffles. Five golden buttons are distributed evenly going down the top on either side between the pink strips. She has a white collar of lace parted in the center of her neck that reaches over her collar bones. It is bound by a pink ribbon with a large bow on the right side of her neck. It has a golden oval decoration in the center and a pair of ribbons trailing from it that reach her hips. She wears tall black boots that are initially folded below her knees, but they become unfolded after she attacks Ferid. [3] After unfolding, they reach mid-thigh and have a slit down to either knee. They have tall golden stilettos.

A prisoner without her regal attire
The loose black sleeves are worn detached, that are puffed up under her shoulders. These run past her hands, becoming wider toward the end. It has two gold buttons at the cuff. A black ribbon is tied into a bow at the top outermost sides of these sleeves, and its tails reach the length of the sleeves. White lace frills decorate the tops of the sleeves, and longer white frills hang out under the sleeves. The white also peeks out in a slit at the puffy part of the sleeves under either ribbon. Under these sleeves, Krul wears a pair of black gloves that are tighter against her skin, and reach her knuckles. Each one has a pair of pink stripes running down from her knuckles to the end of the glove. They can only be seen when the loose sleeves over them are slid back.
On certain occasions, she may wear a black cloak underneath her skirt. It runs from her waist down to her ankles and is split down the center. The inner lining is pink. When leading vampires to gather surviving humans, Krul also wears a military-esque black jacket that trails to her mid-calf. It has shoulder decorations and overly-large cuffs ending in white frills. Each cuff has a line of trimming at either end and has three buttons attached to it. Later, Krul's outfit receives a few changes. She does not don her bat-like hair decorations and wears ribbons instead, and the bow on her white collar is absent.

Acquiring clothes available in the area

After she got barfed on by Shinoa and Mitsuba, she wore her hair down in two long low pigtails worn over the front of her shoulders, and held with hair ribbons. Krul wears casual clothing including a white hoodie with black sleeves. Appearing slightly too big for her, the sleeves cover her hands and there are pockets in the waist area as well. The motif in the center of the hoodie is a picture of a shark with the words "!Danger! Do Not Touch" on it. She also wears tight black leggings that cover her legs entirely, with black boots.

A form change after her weapon is activated

When she has Arukanu drink her blood during her fight against Ferid, Guren, and Mahiru, Krul's form change regains her similar looking black dress attire, but now has sharpened bat like wings attached to the lower back. It has three buttons on each side, the ends of the skirt are white and goes to above her knees, and combined with the the black leggings, covers all of her legs. The detached sleeves are all black, but are still poufy below the shoulders. She regains her bat-like hair decorations and has a white, thin ribbon around her neck.

As with other vampires, Krul views the humans as nothing more than livestock. She does act to gather them to ensure vampires will still have a supply of blood after the world ends. Where their traits are concerned, Krul sees them as foul and endlessly greedy creatures who will do anything for their own personal gain. This view of humans was the reverse of how Krul felt when a human girl where she had fears about blood-sucking monsters.

“ Turns out the true monsters were humans... And my brother turned into the blood-drinking monster. Then he made me a monster too. ” –Reflecting on her and Ashera's perspectives on what monsters are. Chapter 138 : "Really for Real" Page 17

Krul is proud, especially as a third progenitor that gives her the power to back up her reason to be so, further as the queen of Japan. When Third Progenitor Lest Karr challenges her position as the ruler of Japan, Krul becomes angry with his accusations and affirms she never fails, ever. She is temperamental when challenged and does not hesitate to remind her challenger of their place. When Ferid Bathory slaughters the Hyakuya Sect orphans she carefully hid in Sanguinem and kept as livestock, she becomes enraged because he fatally wounded one of the seraph and allowed another to escape. Krul hates the First Progenitor for turning her brother into a demon, a feeling that has not diminished with time.
An effective leader, Krul will lead and deliver announcements on her goals for the humans. Through her own channels, Krul has communications sent out to summon who she desires, where contact was made with other vampire nobles to update them of the human threat and instruct them they were to act. Leading through example, Krul once again shows her appearance to induce others to comply. Not having lesser vampires deal with threats such as Guren when possessed, Krul overcomes them herself. Firm when speaking, Krul orders her troops to not come when she wishes to hold private talks, then directs them to head to head to the next location.

Showing her care to Mika

In assisting others, Krul saves Mika 's life against his will by turning him into a vampire, but this appears to have been done for her own personal interests. When Mika refuses to drink from a human, Krul's response is to provide her blood to him in exchange for making him dependent on her. There is affection behind this, and Krul shows Mika kindness where there are several moments when she hugs him or treats him gently. After developing a close bond with Mika, Krul expresses concern for his family member, Yu . She claims to like both Mika and Yu, however it is uncertain if this is due to her close relation with Mika and concern for his sake, or if this is because she wants to use the seraph for her own purposes.
Also appearing to invest a great deal of trust in Mika, it may be the case that he is one of the few beings to know Krul's true goals. Willing to confide sensitive information that only he heard, Krul would have Mika act as her agent in a mission to reclaim Yu from humans and vampires. Her objective is to locate her brother, Ashera Tepes , who wilfully became a demon under the first progenitor's command. In doing anything in order to find him, Krul even turns Mahiru Hīragi into a vampire when she claims to have information on him. For the few Krul does work with, she will provide considerable resources to assist her allies. This includes training Mika in combat, and bestowing what would be a prodigious gift to him and Mahiru in providing her blood for a vampire transformation. Evidently she allowed Guren to be transported to the airport.
When keeping some secrets safe, Krul often hides them within plan sight. She enabled the children with seraphs within them to live as livestock as any other child would, and neither paid them any mind to not draw attention with her interest shown. Similar with Mika, while she kept him close to the point where he was seen as favored, Krul still largely left him to his own devices. Behaving as normal while keeping many secrets, including what she knows of the "seraph of the end," Krul is willing to be deceitful toward the Progenitor Council to keep her criminal activities to them unknown. At first she was also withholding details from Mika, before being willing to share it. Krul done the same with divulging information to other vampire progenitors on what her plans for the First were. This is done both to satisfy curiosity and put other's minds at rest, then to simply proceed with a plan she has in mind.
In maintaining a business as usual approach where she is patient and happy to coast along, Krul is left vulnerable to developing problems she does not appear to recognize. During her reign, the Japanese Imperial Demon Army 's capabilities grew exponentially with cursed gear developed. While acting swiftly to deal with Ferid's threat of revealing her activities to the progenitor council, Krul may have assumed the beating she administered had settled the matter, which did not prevent Ferid entrapping her further and entwining Krul's course of action with his. Powerless against blackmail, Krul had her to keep her temper in check, and had no way around the inability to kill him where he stands. Similarly, while her response to the threat of the army was prompt in resolutely deciding to destroy them, with her attention elsewhere the humans would still gain a major foothold in Japan. Ultimately, Krul's focus on her plans would distract her enough to fall in an ambush to Ferid. The undefeated and emboldened humans would then sack her city.
Around one thousand years ago when she was human, Krul was happy and cheerful. She was thankful for being born into a noble family. Also caring deeply for her brother Ashera Tepes, after his disappearance with Sika Madu she was distraught. Content to be found by him, Krul was fine in her new vampire state so long as Ashera was around and also displayed a calm side. Krul will do anything to find him to the point to turn Mahiru into a vampire and acquiring information at any cost.

“ No, it's not your fault! What's done is done. It's nobody's fault. ” –Assurances that Ashera should not feel guilty that they are supposedly cursed now. Chapter 117 : "Of Monsters and Demons" page 3

Believing him to have been found again, Krul pressed Ashera to possess the human he was with and cannot understand his hesitation, more so given a danger to them both being around. Since her meeting with Yu and joining his group , she repeatedly asks for her brother to be called by his real name. With the failure to comply, Krul is annoyed to no end. She also finds the group to be utter idiots after the girls accidentally vomited on her as she tried to restrain them. Greatly incensed when they displayed no remorse over their acts towards their vampire queen, Krul thinks none of them would have turned out remotely this stupid had she raised them. She radiates with indignation at their conduct.
Propitiation is effective in appeasing Krul. With her power recognized where she is paid attention to, Krul comfortably fits into her role of a respected ruler. Taking note of her unsatisfactory surroundings, Krul smashes her way through a wall to enter another room. Questioning manners, Krul demanded a demonstration of how sincere Yu was in his conviction of saving Mika. She raised this for Mika's sake, as it would not be fair to what he went though otherwise. Guessing she could help, if listened to, Krul ordered silence and poses questions to ascertain how much others know.
Against what may be a stronger foe, Krul remains remarkably calm. Able to sense that she may be defeated, Krul gives thought to whether she can win. Falling back is not entertained at all. In being struck with a chain weapon , Krul is analytic in wondering what it is for. Even in sensibly guessing that it may be poison, or a spell that will sap her power to make for opponent stronger, Krul displays no worry at all. Rather than herself fleeing, Kurl embraces what would function as psychological tactics namely attempting to have her enemy doubt their chances of victory.

“ Fool! If you can't get away, I'll beat you to death here and now. ” –After kicking an enemy in the head and psychologically inducing them to excape to ensure her own victory. Chapter 137 : "The Queen's Time" Page 3

Time being against her does not rattle Krul, the new weapon of a demonic maw leaves her unconcerned, she is not moved by the ambush of two additional foes. For her close work with Guren and Mahiru, she was not impacted by their betrayal. Krul underwent a marked change after being ambushed by Ferid before, to remaining firmly in control of unexpected situations, both mentally and in terms of physical prowess.
Being outnumbered meant nothing, Krul focused on how she saw her victory. Which outcomes she wanted were also considered. After striking away Ferid she meant to interrogate him later. Deeming Mahiru the greater threat Krul was upfont that she meant to end her as the greater threat.


Owari no Seraph

She has the appearance of a preteen girl and calf-length rosy pink hair, partially done up into two pigtails held with black hairpieces that resemble bat wings. The black headdress is connected by a black headband, and she also has what appear to be short black horns at either temple. Like all vampires she has red eyes, hers are large, sharp and somewhat slanted. Her other vampire traits are fangs and pointed ears.
She wears a short black, frilly style dress with a layer of white ruffles over black ruffles of the skirt. The top has a raindrop shape opening over her chest, and the straps of the top cross before reaching her neck on either side. The top has an open back with two x-shaped crossing stitches tightening it at her waist. A strip of pink goes down either side at the front of her top and ends with red bows above her ruffles. Five golden buttons in a vertical parallel design are distributed on either side between the pink strips.
She has a white collar of lace parted in the center of her neck that reaches over her collar bone. It is bound by a pink ribbon with a large bow on the right side of her neck. It has a golden oval decoration in the center and a pair of ribbons trailing from it that reach her hips.
Krul wears detached, loose black sleeves that are puffed up under her shoulders run past her hands, becoming wider toward the end. It has two gold buttons at the cuff. A black ribbon is tied into a bow at the top outermost sides of these sleeves, and its tails reach the length of the sleeves. White lace frills decorate the tops of the sleeves, and longer white frills hang out under the sleeves. The white also extends in a area at the puffy part of the sleeves under either ribbon.
Under these sleeves, she wears a pair of black gloves that are tighter against her skin and reach her knuckles. Each one has a pair of pink stripes running down from her knuckles to the end of the glove. They can only be seen when the loose sleeves over them are slid back.
She wears tall black boots that are initially folded below her knees, but they become unfolded after she attacks Ferid. After unfolding, they reach mid-thigh and have a slit down to either knee. They have tall golden stilettos.
On certain occasions, she may wear a black cloak underneath her skirt. It runs from her waist down to her ankles and is split down the center. The inner lining is pink.
In the anime, Krul's hair is more distinctly pink than it is in the manga, and the pink details of her ribbons and clothing are darker. Additionally, her heels are often shown as flat boots instead of stilettos. Her hair is sometimes depicted with a third ponytail in the back instead of being down like in the manga.

An effective leader in retrieving surviving human child to ensure vampires retain a blood supply, and in issuing orders. If her words are not heeded, Krul often acts as if physical violence is a be all and end all of a dispute which whilst effective, it is not always so. After beating Ferid she let him leave for him to later reach a point where he had enough information on her to manipulate her. She took the same approach in verbally threatening Lest Karr without fully comprehending what he may have meant when he said he might have been planning to pick a fight with her when he has the ruling of Japan in mind. Her swift approach to settling matters and not really registering the long-term impact that scheming against her can do would result in her downfall as it allowed her to fall and lose her position to Ferid.
Orchestrating her own grand designs, Krul is willing to lie to the entire progenitor council regarding the status of children who bear the seraph gene. She kept some alive for a plot she is deeply invested in. Krul would send Mika on a secret mission to this end. Both to maintain appearances and deal with the rising threat to vampires that the Japanese Imperial Demon Army presents, Krul's solution was to kill them. Krul travelled to Nagoya to see this through to the end.
Unlike the vast majority of vampires Krul has other interest aside from blood. She is affectionate to Mika and appears happy to see him, she did not mind being lifted up and drank directly from. Krul is patient and takes time to help him understand matters. In addition, she has been preparing her own blood for Mika to live off of.


Owari no Seraph

Lest Karr has a short stature and an appearance of a young male with dark-rimmed eyes. His hair is styled into two braids that trail down his back. The right half of his hair is black while the left half is white. He has bangs that cover part of his face. Just like most true vampires, he has fangs, red eyes, and pointed ears.
He wears a small decorated top hat with blue feathers to match his dark, button-up coat, and he wears a white dress shirt underneath. Over the white dress shirt he wears a vest. The buttons on his coat are gold. He has a large bow at his collar and wears white gloves.

Anime: In the anime, he is shown with dark, rich shade of violet-red hair instead of black. His cuffs are shown to be a royal blue as well as the large bow at his collar. His coat is unbuttoned to reveal a white layer of clothing beneath. He also holds a cane. [3]

Lest has an intelligent nature in which his capacity for analysis contrasts his child-like appearance. These two traits and others he possesses make him seem like a good fit for his current rank. His arrogance is shown by the fact that he is quite against his fellow third progenitor, Krul Tepes ', decision-making as the Queen of Japan; even going so far to state that he himself would be perfectly capable of ruling the country. He does not entertain the idea that Saitō has secrets he would want to know in exchange for freedom and shrewdly affirms that he is a liar.
Though despite his disagreements with Krul, it seems he is actually most likely capable of holding all of Europe, as we've not heard of any conflict from that side. When other vampires are agitated Lest Karr deals with the source of a problem, appealing to calmness when interacting with Saitō. After they come under attack against the stronger force Lest Karr orders them all to retreat and readies his sword.
He does seem to show a rather childish side when he questions Urd about his activities and how he rules Russia, however, he can also display his serious and superior attitude when the situation calls for it, as shown when Gabel Parthe continuously goads at Ferid for being a mere seventh progenitor when Lest tells him to be silent. When no longer in the mood for conversation he orders for silence.


Owari no Seraph

Given by his vague silhouette, Nix appears to have long dark hair and horns. He wears a pointed mask covering the upper part of his face.

Like all vampires, he is very prideful and arrogant, even more so with his rank as a third progenitor. He became infuriated when Ferid summoned an urgent call for the Progenitor Council, calling the others low-ranked Progenitors and daring to call the high Progenitors.
However, he seems to hold respect for others that are of similar rank. When Lest told him to shut up, stating Ferid is now the most powerful vampire in Japan with Krul dethroned and telling him to watch his words before he speaks, Nix humbly agreed with him.


Owari no Seraph

Noya is a beautiful 12-year-old boy with milk-white skin, long scarlet hair and eyes that match, and a pair of horns sprouting from his hair. He wears a open skirt like piece of clothing tied around the waist.
Prior to becoming a demon, as a vampire, he retains his long scarlet hair. He wears a sleeveless shirt tying it with a belt in the middle, and a bell bottom shirt. During the dark ages of Greece he has long hair reaching down to his legs, and wears capri style pants with the length reaching his shins.

He is playful and mocking such as repeatedly calling Guren "cute" and takes joy in tempting him with desire and power. He also teases Guren with a countdown and says that he will become a demon soon enough anyway.
Having been separated from Mahiru-no-Yo's demon body, he is shown behaving in a childish and arrogant manner, and tempts Guren to spill all his secrets much to Mahiru's annoyance. He also has a side of him to joyfully jesting to kill others who are close to her.
He mostly doesn't care about anything except for interesting matters, as he always smirks and smiles in any situation that muses him. Prior to become a demon and as a demon he almost never gets annoyed and always tries to amuses himself. Even in dangerous situations he becomes intrigued, amused and even happy.
When Noya is surprised he amuses himself as well and laughs, such as how his reaction when he saw a grown up Yu and Mika together.
Noya does have a serious side that of which such concerning dangerous situation, though rarely seen in such occasion so far it is only seen when he was considering Ashera's threat if he wasn't in his sword form (Asuramaru).
Although rarely, Noya can get furious and confused in some situations, for example when the Death Wail affected him, and Guren with Mahiru ignored him about their plans. As Guren payed no attentions for Noya,


Owari no Seraph

Raimeiki manifests as lightning surrounding the blade. Her true form is revealed to be that of a young woman with sharp slanted eyes, a black horn protruding from her forehead, and long unkempt hair that is held down by a black wide headband that sits behind her horn with some strands sticking out. [2] As a former vampire, she has pointed ears and fangs, which adds to her wild looking appearance.
Her outfit is the most revealing of the demons so far with her top being covered by two black cloth strips that are wide in the middle to cover her breasts and thins out at the ends to be tied around her upper arms near the shoulders and down to her stomach. She wears a black mini skirt that is also tied behind her back, a long matching scarf and arm length fingerless gloves, and her legs are covered past her knees in what looks like shadow.

Raimeiki loves taunting and mocking Kureto as a possession-type demon. She takes pleasure in when she tells him to abandon all responsibilities and give into his greed and desires, often telling him about his lust for Aoi Sangū . She also easily gives up as shown when she was telling him to stop the sealing of Shikama Dōji; tricking him into needing more greed and desires. When Kureto succeeded, she was amused, telling him to keep going. Oddly, Raimeiki also never told Kureto about her abilities other than basic electricity.
However, she also stated that she was desperately trying to protect Kureto from Shikama Dōji by sealing him, which shows her having some level of concern for Kureto.
As one of the chosen apostles by Shikama Dōji she is loyal to him and is very serious, such as scolding Ashera, Yu and Noya for entering a room without permission.


Owari no Seraph

Ky has short brown hair parted to the sides with the side bangs on his left are longer than the right. He dresses in a similar attire matching that of Lest Karr, but without a hat, and is much taller.
Like all true vampires, he has red eyes, pointed ears, and fangs.

Ky seems to possess a laid-back but cautious sort of attitude. When ordered to oversee Ferid Bathory and Krul Tepes' exposure punishment, he says that controlling a third progenitor is beyond him, but he concedes when Urd Geales assures him there will be no trouble. Later, however, whether or not in a serious manner, he comments about becoming a little nervous as he thinks he may have been assigned the nastiest job compared to the other vampires that also arrived in Japan with him.
He taunts Ferid before cutting off his UV light guard and does not hesitate when Ferid asks him to stop. Unlike with Ferid, he politely informs Krul before beginning her torture as well. However, he later taunts Krul when she hands her UV-blocking rings after the torture taunting her that it could be a trauma. He does not appear to be distressed at all when torturing Krul and Ferid, and he does so with a smile on his face. Ky Luc thought nothing of trying to kill others such as Goshi and telling him as much. Approaching Saitō's cage to raise his imprisonment Ky Luc delivered mocking comments on his supposed strength.
In combat he was alert at all times while constantly processing what the enemy's true goal could be. He also considered whether it was a hostage rescue situation or if he himself was being targeted. Acting pre-emptively in response to possible scenarios and remaining level-headed all the while despite greater numbers, Ky Luc was pleased with himself when achieving a set purpose such as blocking attacks. Ky Luc was willing to retreat with Krul taken as prisoner to prevent her rescue, then alert other vampires when he caught up to them.
Highly curious, Ky Luc was keen to learn what his prisoners were looking at when Mahiru-no-Yo's presence could be sensed. This went to extreme measures when he plunged his hand into second progenitor Saitō's torso to investigate the chain components of his body. Similarly, Ky Luc was willing to ignore orders from Urd and free Saitō for the chance to learn more about what he had heard about him.
As noted by Saitō, Ky possesses a very strong sense of loyalty towards Urd and has been stated to be his right hand. As seen during his "fight" against Saitō, Ky wished to fight and kill Saitō himself due to him having betrayed Urd. Similarly, Ky Luc is fine going along with Saito's plan for Shikama Doji as Urd is in favor of it.
Entrusted with administering order, Ky Luc was direct in telling the conquered soldiers of Shibuya that vampires had no interest in them, but they would be killed should they resist. Such ruthless words were reinforced by Ky Luc using his hand to slice into a building and informing them that for every one human who resists, a thousand of them would die.

“ For every one human who resists, a thousand of you die. Understood? I said... Am I understood?! ” –Having cut a building in two, Ky Luc asks defeated soldiers a question. Chapter 121 ; "Last Dawn" page 28

His words understood, Ky Luc appeared quite pleased. His cheerful demenour is not on display perhaps when there are higher ranked vampires around, and when he is anticipating an attack. Unwilling to listen to Yu even with information that may help them, Ky Luc addresses him as a human and orders him to shut up.

“ Shut up, human. Any human who can survive this world is abnormal. We can't trust you. ” –Speaking for other vampires as he addresses Yu with contempt. Chapter 132 : "Battle to The First" Page 16

A sense of anger would return when Ky Luc found Yu requesting something to eat. Where Yu was cheerful in speaking to him and other vampire progenitors, Ky Luc grabbed his clothes and shouted at him to not get cocky.
While it seems Ky Luc had the curiosity to listen in on a sensitive conversation taking place, he was not particularly interested in the specifics. For a grand plan of taking over the First's goal of resurrecting angels and humans who had perished, there was simply no enthusiasm from Ky Luc on such a seismic happening possibly taking place. Similarly, where Saito and Urd were potentially working with a human, of which it may be expected that Ky Luc would participate in such a plan, he felt nothing on that. This lack of enthusiasm for these unconventional happenings may be a result of the vampire apathy towards life of which has its impact on him.

“ I'm so not interested in all that complicated stuff. It's not like there's any meaning to life in the first place. ” –Thoughts on topics such as angel and human resurrection affected by his existence as a vampire. Chapter 140 : "The World I Want" Page 28

When notably strong members of the Moon Demon Company had escaped their confinement, Ky Luc appeared to take it upon himself to pursue and kill them without consulting others on whether that would be best. Not paying much mind to whether the hostages could be valuable, Ky Luc also hunted them in his words by himself. Eager for a fight, Ky Luc was also eagerly ready for the surprise arrival of Ferid who he was similarly keen to battle.

“ Even if you stop, I'll still kill you all! Try to put up enough of a fight that I can kill at least a bit of time. Sword! ” –Catching those who escaped and his eagerness to fight. Chapter 140 : "The World I Want" Page 33


Owari no Seraph

In the light novel, Aoi appears like a taller and more buxom Mitsuba Sangū with straight shoulder length blonde hair (which is lighter than Mitsuba's hair color) pulled into pigtails, which were on the back of her hair than to the sides, unlike Mitsuba; her bangs are parted on the right, which were held them in place with two hair clips. She has purple eyes as well.

Anime : In the anime, she has green eyes. [2] LN manga : In the Catastrophe manga, she has blue eyes.

She wore the First Shibuya High school uniform, a sailor fuku which consists of a blouse with red trim around the collar with a grayish blue sailor-style collar which also has red trim and a similarly colored skirt with a belt. The red uniform ribbon which is thinner than normal sailor fuku, is attached to the bottom right end of the collar. The school's emblem is located on the right breast. She wears thigh length grayish blue stockings and dark blue dress shoes along with it.

Aoi would usually appear at Kureto Hīragi 's side as his personal aide. Possessing a good head on her shoulders, with a calm countenance when assessing every situation and a great degree of vigilance, she has her master’s complete trust. Aoi is stoic, serious, and appears to follow his every order without hesitation, no matter how gruesome or how heartless it is. She also appears to have no qualms in killing, shown when she annihilated Seishirō's bodyguards immediately. In Catastrophe book 7, Aoi has declared that her loyalty belongs to Kureto instead of the Hīragi family, even when she knew that her loyalty could possibly get her killed. Her dedication and loyalty to Kureto is so strong that she refrained from crying out in pain after a sniper (sent by Tenri) shot off her foot, so Kureto could keep his calm.
Aoi and Kureto appear to know each other very well, as she is nearly always present next to him. She's able to understand her superior's orders through body language alone, and the two are a silent and efficient team.
Additionally, Aoi dislikes activities that waste her time and tends to look down on the Ichinose family such as Guren. She also does not appear to have a good relationship with her little sister, Mitsuba. This was shown when she ignores Mitsuba and then proceeds to sacrifice her comrades without hesitation in Nagoya under Kureto's command.


Owari no Seraph

Basteya is an androgynous vampire with medium length black hair that reaches down to their neck. Their bangs are uneven yet in any case the length on all sides leaves their ears and thin eyebrows visible. Like all true vampires, Basteya would have red eyes, along with fangs, and pointed ears.
They wear a white long coat with six buttons in the center, [3] two pairs of two lines on each side, and at the end of the long sleeves are dark cuffs with two white lines. Under the coat is a black collared dress shirt with white trim on both sides of the collar and a white tie.
The lower section of the coat is parted displaying white pants along with black boots that reach below their knees. Belt loops hold a black belt keeping the coat around their waist to which their sword scabbard is attached to. [4]

Basteya would attack when a foe was distracted, slashing at Shinya with his back turned and a second time when Shinya called to Kureto, smirking as he done so and wasted no time in trying to finish a fight. They were haughty to those perceived as beneath them referring to Ferid as a "little stray mutt" and not answering his question, it was none of Ferid's business on account that he had been discarded. Ferid considered him awfully stuck up for a dog that's still chained.
Basteya, in turn, has displayed immense loyalty to Rigr Stafford and has displayed little to no fear or hesitance in willingly allowing him to absorb and feed off his own life force in order to further boost his own in order to Battle the First Progenitor , showing absolute faith in his plans and abilities. Basteya has also shown a level of closeness to him, as seen where he still refers to him by his original name rather than his new alias as Saitō with the Second Progenitor in turn seemingly not minding at all despite his preference for his new name.
Overall, Basteya was remarkably calm in dangerous situations such as nonchalantly deflecting Ferid's ambush from behind whilst they were still talking. Additionally, Basteya was not remotely concerned about the arrival of Guren's squad armed with weapons, neither the sudden appearance of their human ally who appeared suddenly via a portal.

“ If the Demon Army has any promising researchers, add them to the Hyakuya Sect. Everything we've fought for over the last thousand years was for this moment. ” –Incorporating defeated members of the army that was just overcome in remaining committed to a long-held plan. Chapter 121 : "Last Dawn" Page 34


Owari no Seraph

She has short brown hair reaching her chin and violet colored eyes. She wore casual attire including a yellow hoody covering an orange shirt underneath. She was also wearing a blue skirt reaching near her knees and grey socks with brown boots.

Understandably afraid of the Four Horseman of John , she had the sense to try and hide before running from it again. Under duress, she was willing to lie, but this was done to defend those she cared about. Under normal circumstances, she showed a sweet and caring disposition.


Owari no Seraph

Crowley had blue eyes, with auburn colored hair, and thick eyebrows of the same color. For his hair length, it was short overall, yet long enough on the sides to reach past his jaw where his ears were kept visible. Although sections of his hair were partially over his eyes, where there was a parting in the left centre, Crowley's vision appeared unhindered. His looks were said to have made him quite popular with women.
For clothing worn around the time of the crusades, Crowley was seen wearing a black tunic where the top was held together with a cord like fastening in an X shape. The tunic's length enabled it to cover part of Crowley's waist, and it was held around him with a brown colored belt with a golden frame-style belt buckle that featured a single prong. The tunic was worn over a seemingly white undershirt. The gray colored sleeves may have been part of the same garment as the tunic, or a separate undershirt. Either way they were long-sleeved, yet the length left his wrists showing when his arms were in a bending motion. Crowley wore gloves that were similar in coloration to the sleeves.
Thick leather like shorts were worn over Crowley's thighs, of which the ends had a light gray section. There was a split at the front of this area, to be practical given that leg movements such as crouching could result in the clothing being torn were they not implemented. Brown colored boots were also worn, of which material reached upwards into the shorts to provide total coverage. On other occasions, Crowley wore long light colored pants from under the lower section of his tunic, and over the top of his dark boots.
His merlot like colored cape was ceremoniously worn mostly over Crowley's left shoulder. Apparently it was incorporated to be a part of the tunic on account of seemingly being attached to it via a black band near his left chest area. The cape having somewhat of a collar, it was worn over his entire back where the length would have reached near the ground when Crowley was standing.

Calm, he is laid-back and gets along well with everyone. Crowley also cares deeply about his comrades. Training hard to protect them during the Crusades, he is also brave. After their commander perishes, Crowley leads the group due to his commander's final order. Crowley tends to smirk a lot.
Despite his strength and capabilities, Crowley knows when he is beaten and gives up after a vampire slaughters his comrades and has him by the neck. After surviving the Crusades, he suffers from PTSD and turns away from rising in the ranks of the knights. This may indicate that his ambition is hindered by illness in this case. Even so, the care for his friends and former comrades energizes him to solve the mystery of their deaths, and also avenge them.
He loses his human life trying to warn his former comrades to escape. Having the resolve to do so, Crowley fights against Ferid until he can no longer move.


Owari no Seraph

Whilst a demon, Mika appears as a child with the addition of two large pointed black horns on top of his head. Unlike as a vampire where he had red eyes, demon Mika has his original light blue eyes [1] Also unlike Mika as a human child, this demon has visible pointed ears that can be seen from his yellow, blond hair.
Demon Mika wears clothing that is formal for his young age including a white double buttoned dress shirt with a banded black double buttoned collar. His pair of dark colored shorts were down to his thighs. He also wears a pair of sturdy black boots that reached up near to his knees. The dignified manner of attire was out of place for the respective time period he was in, it is not something that Mika was seen wearing during present times. Over all of this, demon Mika was cloaked in a hooded dark cape with the interior a lighter color with the length down to his shins. It was worn open with the front part of the clothing visible and held together by a crossed strap across the chest. The hood was large and rigid appearing where the material did not rest over his head. It may have had openings for his horns or part of the design included a material to cover them and there was a long part of the back of the hood. Just as prominently was an exceptionally long upright shadowy tail like appendage that curled in several places.
Upon forming a contract with Yu, he physically changed into a teenage appearing demon version of himself with a new manner of clothing. Demon Mika's triangular shard shaped horns were now visible with his wavy hair shown, in addition to his vampire like ears. He is wearing a dark colored, sleeveless parka jacket like clothing that has a gap partly showing his chest, where the raised collar has his neck visible. There is a black fur like trim around his shoulders. A strap with a middle light-colored line, with black lines running either side pattern is across his chest, with a single similarly designed band around his bicep. Mika also wears dark colored fingerless gloves. The circling wisp like tail that he had as a child is retained. A lighter colored cape that is darker at the top, before becoming lighter further downwards, is worn over his back where the length is the same as his jacket in that it ends at Mika's thighs. The cape is parted in the middle where the tail can appear from and is somewhat tattered at the ends.
The sword that Mika can form into is dark overall in coloration, both the blade and sheath. The grip is dark with two thin light parallel lines running vertically down it. The pommel is lighter in coloration and stylized with a circle pattern int the centre, with metal like ridges on the outside. The design is symmetrical much like the handle patterns are. The guard is formed differently on either side, similarly, one side of the blade is lighter in coloration and has a pattern on its side of the fuller, where the dark side of the sword does not.

Showing consciousness within a landscape, demon Mika contemplated demons and how bright the world was. He remained expressionless at experiencing a thirst though acknowledged that he needed to hurry. Remaining indifferent even as his arm started to disappear, demon Mika concentrated on a course of action in locating a human, having the instincts to devour their desires. Whether he was bothered by the sun or his arm he made no effort to alleviate his discomfort.
With unfamiliar people such as Mika and Yu he deemed them precious and desired to protect the world they were in for them. At feeling that someone was an invader, demon Mika immediately attacked Kiseki-o with his next decision being to devour the invaders' desires. He showed no fear at being attacked. At first running, demon Mika took to firing at a pursuer and took measures to deliver on his intent to defend Mika and the illusionary Yu once it became clear that they were being targeted. He was surprised at Ashera managing to break into a building he had created to block his path, but returned to composure when one of his attacks missed with the remark that it was annoying. Similarly, he had little regard for his own arm being struck but expressed a deep sense of shock at the prospect of Mika and the Yu being eaten.
With threats, Mika acted to defeat them, even after forming a contract with Yu. Straight away setting about consuming desire, Mika focused on the future, but first ascertaining how powerful they could be against the First. Working with Yu, he was wary of seraphs speaking about sinners, and shouted to not let the First get away.

His dark hair was short, and wore red-framed glasses. He wore a long sleeve long white lab coat, grey trousers, white shirt underneath and a red tie.

He was straightforward in explaining the situation at hand concerning Mirai.


Owari no Seraph

She had long brown hair reaching below her shoulders and had darker brown eyes.
She wore the high school uniform, a sailor fuku, which consists of a grey blouse with black cuffs that have teal trim in the middle.

She wore it with dark blue knee high socks and white shoes.

Not much is known about her before but, after being rescued, she acted shy around Yu . She tells him she loves him and had written what how she feels in a letter she gives to Yu.

He is physically a slender male, where a distinguishing trait is his long, silver hair that reaches his hips. Having bangs and a lock of hair over either ear so that they are visible, Ferid keeps his hair tied back into a pony tail held with a ribbon. The ribbon has stripes in the first chapter, but it is replaced with a black one after he is defeated by Krul. The ribbon tails trail to his shoulders. Ferid also wears a pair of red diamond-shaped earrings which dangle from either ear. As with all vampires, Ferid has pointed ears, with red eyes, and fangs.
Ferid's slightly changing attire is composed of several components, including a suit and a long coat. A white long-sleeved shirt with a decorative cut is worn over his posterior. This is split down the center and reaches his mid-calf. This has a black line with dark gray rhombi intermittently dispersed along it. There is originally a stripe on his left side as well, but this disappears after his defeat by Krul. It is secured in place by a wide black belt with a large buckle around his waist. The buckle rests over his left hip. The cuffs of the shirt are black and have four gold buttons down the outside. White lace ruffles comes out of the cuffs over his hands. Ferid wears white gloves.
The pair of white pants he dons are fitted within black boots, which reach his upper thigh. The boots have four golden buttons at his thigh and three at his calf. The boots are white at the toes, sole, and heel. A pair of small black ribbons meet over either heel and are kept in place by a small white button detail in the center.
A cape compliments the noble appearance. His white cape with a decorative cut over is over his shoulders and arms. It reaches to his waist in the front and down to his upper thighs around the back. The cape has black shoulder details as well as the black vampire insignia on the left shoulder. There are also two black buttons on the right. A gold ring connects to the vampire insignia and is attached to a chain running under his ruffles. There are gold decorations hanging from this chain. A wide dark gray strap beneath this cape moves from his right shoulder to his left hip. This has three strips running down it, with a small mark over each stripe at set intervals. Ferid wears a black collar that originally has a pair of two white stripes lining it in the first chapter, but he replaces it with a similar collar with one stripe afterward. The collar is decorated with a scarlet bow at the base of his throat. The tails of the ribbon reach his lower chest. Two layers of white ruffles are present beneath the bow and reach his mid-chest.
After being burned for treachery, Ferid's hair and noble garments were both incinerated. His hair began to grow back virtually immediately at the moment he was freed where it reached his ears. Where Ferid's hair soon recovered to the original length, he wore it untied. His clothing was now made up of casual attire consisting of a simpler shirt, with trousers. A black shoulder cloak, and gloves serve as ever distinctive signs.

Even as a human child, Ferid has an excellent memory and memorizes things easily, which leads him to become bored quickly. Raised strictly in a royal household and prepared to be a saint seemed to have no bearing on early psychopathic tendencies. He would remark that he loved his mother whilst bloodied and armed with a sword. Once a vampire much later he would retain this mentality when declaring that he loves his 'papa' Saitō so he has come to kill him. He was deemed "Abnormal" by Saitō, and has always been so even during the days he was a human child. This seems to have sustained itself to Ferid's teenage years as a human.

“ Not all that interested, really. Wealth. Power. Royalty. None of it interests me. And it's not only that. Maybe it's because I'm going through puberty, but... ...I don't see the point to living at all. Well... I guess if you order me to, I'll do it. ” –Sharing his disinclination to help with his brother's kingdom. Chapter 134 : "Reincarnation Rondo" Page 9-10

Taking to isolating himself in a field on more than one occasion, Ferid found he could not suppress what he found were self-destructive urges. Additionally wishing that he had never been born in the first place, Ferid found such thoughts were being repeated in his mind. Feeling he was being driven mad, Ferid also took issue with the world itself.

“ Just the thought that we'll get reborn right back into this stupid, dull, idiotic world is enough... ...To make me positively terrified of death. ” –Speaking aloud to himself of his fears on death, but only in the context of not wanting to be reincarnated. Chapter 134: "Reincarnation Rondo" Page 17


Owari no Seraph

Not seen directly on account of existing within a young human girl, the seraph's discernible traits are its four large feather based wings often outstretched on either side. Its presence is also indicated by what may be its true eyes visible in the place of Mirai's. They are golden in color where the sclera is black. There are unique curse mark style markings that cover her skin.

Anachronistic in its speaking, the Fifth Trumpet's immediate response to humans before it was to lambast them as wretched sinners, then act to kill them all indiscriminately. When under the control of army forces, the Fifth Trumpet obeys verbal directions given to it by humans. Otherwise inactive when close by to the beings it vowed to destroy, the seraph will fight alongside them and commence attack when ordered to. In this state the Fifth Trumpet acts to fight against another seraph. Such malleable, at odds behaviour with what was displayed initially, is indicative of what is controlling it rather than the seraph's regular nature.


Owari no Seraph

Guren is a tall, young man with medium length black hair similar to an overgrown wavy mullet, with slightly overgrown messy bangs parted in the middle and complementary violet purple eyes. He is considered quite handsome according to some girls who are infatuated with him. He is regularly seen in uniform based attire.

In his childhood days Guren's outlook on life was simple until Mahiru Hīragi entered his life. Aware of the barriers between them due to their family backgrounds, when he was forcefully separated from Mahiru and treated with contempt for being part of a lowly branch family, Guren felt guilty for being too weak in physique and power to not reach out for what he wanted back then: Mahiru.
He was strongly devoted to Mahiru Hīragi, displaying the strength and goodness of his heart. Even when she betrayed him multiple times, he couldn't leave her alone and keeps trying to save her. Indeed, when pressured with the death of Sakae, Guren showed he could not bring himself to actually kill her, opting to commit suicide with her, which failed. Even after Mahiru killed all his friends, as she was the only thing that was left, he didn't kill her.
Although he treats Mahiru-no-Yo coldly, as later on revealed Guren never let go of the guilt and sadness he felt over his failure in his childhood days. Along with the guilt for triggering the apocalypse to save his friends. Guren shows regret over what he had done to the world and now wants to undo it.
Guren had to learn the hard way that he wanted to rely on his friends again after the trauma he had experienced in his childhood. Due to his friends, Guren would become a wise leader who values teamwork, co-operation, and friends, determined to ensure the survival of the human race from demons and vampires. He actually cares a lot about his subordinates, and considers his friends to be his family, both before and after the apocalypse. When Yūichirō Hyakuya tried to join the Moon Demon Company, Guren refused until he made friends. Guren is also courageous and loyal to his friends, even to the point of ordering Shinya to abandon him and take command for the group in his stead, so they can escape, while carrying on with their mission.

“ Anyone with a heart cries when a friend dies. But we can't afford to do that right now. We have a mission to complete. ” –While troubled at others dying, he remains practical given the situation. " Who's Pulling the Strings? "

Guren sometimes appears to be indolent, but in truth, he really works hard just in areas other than official army meetings and instructing classes for examples. He keeps many secrets to himself, and has no difficulty lying about them. Concerning long term plans to dethrone the Hīragi Family , this, and his sleepiness, it is partially a result of a desire pressed on him upon being possessed by Mahiru-no-Yo. It is made clear when Guren is possessed, and his true desires come to light, that he wants to change the status quo and hierarchy. Willing to work with what should be sworn enemies, whether people or vampires hostile to him, Guren proceeds with plans that are beneficial in the larger picture. From his school days, not showing enemies what he is capable of, or what he wants, and allowing them to have a wrong impression of him has been a practice. Further long term, and forward thinking plans were acquiring the bodies of those others around him knew, to keep in storage.
Casual in his dealings with others, Guren is flippant even to ruling members of the Hīragi family where he thinks nothing of simply walking out a meeting he is not interested in. Laid-back, he also fends off Yu's surprise appearances, and thinks nothing of sudden unanticipated actions such as flooding a room with Mahiru-no-Yo's cursed gear effects. His displays such as this, and reminding Yu to not attack a superior officer such as himself are unpretentious, not done to impress, rather ascertain a situation such as who can handle cursed gear, or dismiss a tedious ordeal to him as fast as is practical. Often answering Shinoa's merriment with raillery of his own, he is not aloof in conversation despite his ranks and titles unlike his contemporaries. While appearing serious in administering a disciplinary, behind closed doors Guren informally speaks with Yu and shares with him his true plan in mind.
An effective commander, Guren locates the leaders on the battlefield to engage them directly. Guren rallies soldiers with the harsh truth many may not survive but the goal is not to come back alive, it is to be victorious no matter what. To help others distinguish when it is okay to be facetious or serious, Guren will issue a reality check involving a practice fight, where he holds back to prevent them injury, to lay bare the consequence of failure. As a fighter, Guren relies on brute strength involving powerful strikes and emissions from his cursed gear. He makes use of relying on his team, and luring others into traps. Sheathing his sword, to deliver an unexpected spell tag with other feints are used to give himself an advantage. Pleased to be in control of a situation, Guren will also remark on how things are going his way.

“ If Mikaela kills you to come back to life... ...Do you think that he'll want to go on after you're gone? What about if the shoe was on the other foot? Would you want to come back to life if it meant killing Mikaela? ” –With what he knows of how Yu and Mika matter to one another, Guren uses this to dissuade Yu from allowing his body to be taken over by what he regards as a demon. Chapter 101, page 27

His overall pleasant demeanor, and repeated claims of putting family first, with good natured intentions of wanting to help others is extraordinarily successful in allowing a conspicuous manipulative streak to go unchecked. Comments on a prophecy masked his alliance with Ferid when locating Yu. He justifies human experimentation due to the state of the world necessitating it to survive, and can become a demon to mitigate any qualms he may feel about serious wrongdoings. Building an extensive rapport with Kureto over time enables him to talk his way out of the accusation that he is gathering black demon holders for a coup, then continue on his way with a mission. After inflicting serious injuries on others, Guren can also literally get away with murder after murdering a sibling with the pacifying incentive that everything will be alright once he resurrects everyone. A tearful and heartfelt display evidently makes it all the more convincing.
Moments of blackness cover Guren's thoughts when he is recalling the death related event of eight years ago. Guren has commented how he should have died with the others. Very calm in saying this, such moments of resigning himself to this fate perhaps come when he feels death is near, such as when he and Mahiru failed to defeat Krul after they betrayed her.

“ The both of us are walking dead. We should've died together with everyone, eight years ago. ” –His view of his and Mahiru's situation after being unable to defeat Krul. Chapter 137 : "The Queen's Time" Page 25


Owari no Seraph

He is a tall, young man with small purple eyes. His medium length black hair is parted in the middle with the bangs hanging over his forehead. Whilst often slightly tousled Guren occasionally has his hair slicked back during the midst of skirmishes on the battlefield.
For clothing he wears the standard JIDA uniform, which consists of a long-sleeved, double-breasted black coat with two rows of gold buttons down the front, red details including shoulder epaulettes, gores at the bottom, and stripes on sleeves. Other decorations include gold aiguillettes and white fourragères worn on the right shoulder. This is attached to a stylized cherry blossom decoration pendant at the center of his collar, and two bars with unit insignia medal below them on the left.
He further wears a pair of white gloves, a black on white armband on his left arm, and a similarly striped black and white web belt with a frog for his sword on the left, and a gold waist-plate. In addition, he also wears the uniform trousers with two white belts strapped around his left leg and black shoes.
When a Namanari, Guren retains his violet-colored iris, yet they are circled by a bright red color.

Guren would become a wise leader who values teamwork, co-operation and friends, and determined those were necessary to ensure the survival of the human race from demons and vampires. When Yūichirō Hyakuya tried to join the Moon Demon Company, Guren refused until he made friends.
Whilst Kureto lists them as weaknesses, Guren is felt to possess love, friendship, and honour but never learns to set aside his emotions in order to lead. Guren felt it was barbaric that vampires were being starved in experiments to turn them into cursed gear. Yu describes Guren as someone who likes to talk, and he gives good advice.
Sometimes pretending to be lazy, in truth, he really works hard. He keeps many secrets to himself and has no difficulty lying about them. He also plans to dethrone the Hīragi Family. It is made clear when Guren is possessed, and his true desires come to light, that he, along with Shinya Hīragi, wants to change the status quo and hierarchy.
When enduring hardships in battle he will focus on winning and take the most direct path to that. Whether working as a squad and never intending to fight a foe one on one, to using a spell tag to keep Mika's sword in him to allow Yu to make the hit, Guren will persevere. This applies to when he is being beaten, he will joke and only speak with misinformation when being questioned.
