Yu Ominae 
 is the main protagonist, stationed at ARCAM's Japanese branch. He is also a former member of COSMOS. He is known for being a high school delinquent to his teachers and classmates, but he is also secretly a special Spriggan agent for the international conglomerate ARCAM Corporation. As such, Yu gets thrown into missions in and out of Japan when out-of-place artifacts are involved in a mission. Yu is called upon by ARCAM to conduct black ops for the company, which results in several disruptions from his studies. His most dangerous mission to date was to be deployed into the South Pole in order to eliminate the South Pole Shrine. After the successful operation in eliminating the rampaging Fire Snakes from the South Pole Shrine and defeating Markson's Trident forces in the South Pole, Yu was seen attending college after graduating from his high school. He is still posted at ARCAM's Japanese branch, where he attends to a mission in Mexico in order to secure the Gold Statue of Pachacamac and ensure the safety of his classmate, Nanako Kondo. He is voiced by Chiaki Kobayashi (Japanese) and Kyle McCarley (English) in the 2022 ONA adaptation. Jean Jacquemonde 
 is a French Spriggan operator who is based in ARCAM's French branch. His werewolf appearance is mainly due to use of ancient biotechnology that gave him the ability to shapeshift into one. During his time with the Spriggans, he actively assists Yu Ominae in battling enemies of the ARCAM Corporation from Turkey all the way to the forests of Japan while fighting foes from Machiner's Platoon soldiers to brainwashed COSMOS child soldiers.

Eventually killing his assailant in his werewolf stage, Jean overcomes platoons of Machiner's Platoon soldiers sent to stop him. When Jean is deployed to Romania on a mission, he confronts his father who told him of his heritage. In an operation in Ecuador, Jean is severely wounded by Oboro and left for dead. Fortunately for Jean, Percup Ramdi performs an operation that manages to heal Jean of his wounds and further accelerates his rate of self-healing. In a mission to prevent COSMOS from extracting Rie Yamabishi to the US, Jean storms a US Army base in Japan along with Yu and Oboro. However, they are unable to prevent COSMOS forces from escaping. Jean, grudgingly, teams up with Iwao Akatsuki and Bo Brantz, two of ARCAM's most fearsome enemies, in sabotaging a Trident operation when Larry Markson attempted to harness the power of the South Pole Shrine in order to take control of the world. With Bo's death, the three took on Larry's forces before they were able to get rid of the Fire Snake with the help of Yoshino Somei, Rie Yamabishi and other ARCAM personnel who were forced to assist Trident in gaining access to the fiery artifact. He is voiced by Yōhei Azakami (Japanese) and Xander Mobus (English) in the 2022 ONA adaptation. Tea Flatte

Later on, she is dispatched to Britain to subdue a group of Neo-Nazi militants that are trying to secure the Holy Grail. She teams up with Yu and Yoshino in defeating Kutheimer's group when the Adolf Hitler clone attempts to use the Vajrayana scepter after her and the other ARCAM agents and Yoshino before it blew up due to its overuse.

Later on, Oboro returns to Thailand and assists Yu and Yoshino in fighting against Cheng, who had honed his Qigong skills in order to seek revenge against Oboro. Later, Oboro apparently betrays ARCAM due to his attacking an ARCAM Special Private Army detachment in Pakistan and is able to defeat Jean Jacquemonde in his werewolf form, thereby placing him in critical status. An enraged Yu defeats Oboro in single combat, but Oboro walks away with bruises on his face while smiling at his former student.

Eventually, Oboro paralyzes Bo, but also encourages Bo to retrain himself and forget his usage of steroids. Yu later encounters Bo again during an operation to recover the Holy Grail from Kutheimer. This time, Bo has retrained himself without the use of steroids, but is still unable to defeat Yu.

ARCAM Corporation is a company that was founded in the United States and has branches covering all countries from across the globe. Its mission is to covertly secure and destroy all ancient artifacts (items, machines, ruins, etc.) from all known enemies that may use them for their own benefit. Its breakthrough was the refinement of Orichalcum, a strong metal that was used for ARCAM's Armored Muscle Suit and Yu's combat knife. MJ-12 and Trident Corporation were able to refine their own Orichalcum suits, mostly from ARCAM's research. The spelling ARCAM is said to be a misspelling of Arkham. ARCAM Private Army: ARCAM's paramilitary wing whose duties vary. Their main purpose is to conduct operations on various artifact locations and its aggressors, ranging from private corporate military wings to national militaries. Spriggans: One of ARCAM Private Army's divisions, consisting of special agents recruited for covert work in hostile areas without compromising the company. Trident Corporation: Founded by NATO as an R&D Division, it went rogue for unknown reasons and was soon declared as an illegal organization. It searches for ancient artifacts in order to refine them as potential military weapons. Currently, it is heavily funded by the European Campbell Company, American Glovers Heavy Industries and Japanese Takasumi Zaibatsu. Its greatest breakthrough, apparently based on ARCAM's Armored Muscle Suit, was the Orichalcum Armored Machine Suit. One of its users was the Trident Corp. operator Iwao Akatsuki. COSMOS (Children Of Soldiers Machine Organic System) is a black-ops unit of the US Army. Most of its operatives are child soldiers who were kidnapped by CIA agents and US Army soldiers from around the world and brainwashed. References
