Yūya Tenjo is an overweight, short and meek middle school student who is bullied at school and tormented by his family, except for his grandfather who is the only person who cares for him. When his grandfather dies and leaves Yūya as the sole heir of his house, his parents expel him from home, and he is forced to live there alone. Inside his grandfather's house, Yūya discovers a portal to another world, where he obtains the power to change his life forever. Characters

 The main protagonist, he was tormented by both his classmates and his family for his ugliness and obesity, which are caused by some genetic deficiency. He inherits his grandfather's house, where he finds a portal to another world. After killing a powerful monster using the weapons he found in the house, Yūya grows stronger, taller and handsome, and obtains special powers by defeating enemies like in a video game. Because his previous isolation made him a loner and shut-in, he is both very self-conscious about his improvements and quite ignorant of the effects they - especially his new, improved looks and charisma - have on his environment. He travels back and forth between both worlds, using his newly obtained skills to improve himself, gaining a lot of notoriety and making friends and enemies along the way,

Daughter of the chairman of the prestigious Ōsei Academy and a student council member. She takes an interest in Yūya when he tries his best to defend her from some thugs before his transformation. When she meets him again after having done a thorough background check, Kaori invites Yūya to study at Ōsei with her, and he accepts. She becomes a close friend at school and develops romantic feelings for him; she is also the first person Yūya confides in about his secret access to the other world. The first princess of the kingdom of Arselia, which lies in the other world. She is a half-elf, the result of a love affair between the reigning king and a high elf slave mother, subjecting her to racial hatred and attempted assassination by her half-brother. Despite her hardships and headstrong nature, she is compassionate and shows wisdom beyond her years. After Yūya rescues her from a monster, she becomes infatuated with him and tries her best to win his affection. A popular model who partnered with Yūya in a photoshoot and developed an interest in him since. An energetic female member of Ōsei's track and field team who becomes interested in Yūya after watching his vastly enhanced athletic abilities in action. Her most notable feature is her distractingly generous bust size. A male student at Ōsei Academy with hair bleached to a light brown and an extroverted personality. Though a natural athlete, he has not joined any of the school's various athletics clubs, preferring to be a guest member at most. A male student at Ōsei Academy and Ryō's friend who wears glasses and is rather timid, as expressed by a slight stutter. He is a member of the school's video games club. A male student at Ōsei Academy with silky blonde hair and a good-natured but overly dramatic personality. Habitually labels himself the "Young Noble of Ōsei". A confident and slightly mischievous female student at Ōsei, and Akira's self-appointed disciplinarian. A female student at Ōsei Academy with short, blue-tinted hair and perpetually sleepy-looking eyes. A silver-haired girl from Arselia born into poverty, who became a vicious killer in her fight for survival and was consequently recruited into the Guild of Darkness, an organization of professional assassins, where she became infamous as The Headhunter. She is hired by the realm's first prince to eliminate his stepsister Lexia, but upon encountering Lexia's protector Yūya, she falls in love with him, and after Yuya and Lexia forgive her, the princess takes her in as a personal bodyguard. Her main weapons are wire-like threads which she can exude from her fingertips. A Black Fenrir puppy who was found and adopted by Yūya during one of his outings in the Forest of Weald. Like Yūya, he levels up when confronting monsters in combat, and grows stronger and smarter than his small size would suggest. He is named after the kanji for "night" (夜) in Yūya's first name. A young Mōju boar from the other world who joins Yūya as his second pet. Akatsuki has several innate holy powers (including abilities to heal, sanctify an area, and perform exorcisms) which are strong enough to defy even a Vile's powers. Yūya has named him for his red fur, which reminds him of the scarlet hue of the sky just before dawn. A member of the "Divines", beings from the other world who have gained mastery over their defining element (in his case, the ability to deliver super-powered kicks) to protect their world from their evil counterparts, the "Viles". While appearing as a white rabbit, he is sentient and capable of telepathic communication. After seeing Yūya's potential, he trains him as his successor in his Divine Kick technique, in exchange for Yūya teaching him magic. A member of the Viles, the counterparts and nemeses of the Divines. She is the former apprentice of the Archer, a Divine who was killed by humans, compelling her to become a Vile to take revenge on humanity. She wields her master's bow, which can produce arrows with varying effects at her will. Yūya's recently deceased grandfather who was secretly a traveler to an alternate magical world, and the only person in Yūya's family to treat him with kindness. His loving support is Yūya's moral anchor in his decisions to help people in need. Yūya's twin brother and sister, and his juniors by a year. Because of their (compared to their brother) far better looks, they have been far more favored by their parents, leading them to adopt the same spiteful superiority against their older brother. After Kaori invites Yūya to Ōsei, they hire the Red Ogre Gang for a raid against the school, but after Yūya defeats them all, the Ogres' leader tries to kill them in revenge. They are rescued by Yūya, however, leaving them in deep shame over their past behavior towards him. One of Yūya's former schoolmates and tormentors, and a member of a violent gang called the Red Ogres. After Yūya's transformation and transfer to Ōsei Academy, he and the other Ogres participate in a revenge raid against Yūya and Kaori until Yūya single-handedly defeats the entire gang and they are arrested by the police. An enigmatic person from the other world who, like Yūya, achieved a vast physical and mental prowess, but declined assuming divinity because he valued his humanity. He was the one who built the house which the portal in Yūya's house connects to, in the midst of the Forest of Weald (also known as the Demons' Den), the most monster-infested region in Arselia. Yūya later finds the Sage's remains inside a cave in the forest, along with his journal which enables him to learn and wield magic. The king of Arselia and Lexia's father, who dotes on his daughter. He wields a magical sword named Grackle, which is capable of cutting through almost anything and which he wields in his fits of berserkism whenever he suspects any wrongdoings committed against Lexia. A famed knight of Arselia, and the leader of the squad of royal knights comprising Princess Lexia's personal bodyguards, who has to suffer the antics of both the princess and her father. The first prince of Arselia and Lexia's older half-brother. While Lexia and he were still children, Lexia once accidentally unleashed her magical power on him, burning his face. Ever since, Reigar has harbored an obsessive hatred for Lexia and is responsible for the assassination attempts Yūya ends up rescuing her from. The chairman of Ōsei Academy and Kaori's father. He believes Yūya, who saved his daughter, is the right student for the academy and endorses his transfer to Ōsei. Yūya's homeroom teacher at Ōsei Academy. Languid, still single, a heavy boozer, and despite the impropriety for her position, she spontaneously proposes to Yūya during a survival-themed school field trip when she witnesses his skills in turning various foraged ingredients into a gourmet meal. The school nurse of Ōsei Academy. A creepy person, she has an obsession for hazardous treatments, compelling the students into avoiding her infirmary (which is one reason for the school's impeccable attendance record). Her name is a joke reference to the Japanese underworld. A muscular but cordial professional photographer who works regularly with Miu. Company President

The unnamed female president of the talent agency Star One, and Miu and Hikaru's employer. After the issue featuring Yūya and Miu's photoshoot becomes a major sales hit, she becomes obsessed with hiring Yūya to model for her magazine. Media
