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.

Jean Jacquemonde (ジャン・ジャックモンド, Jan Jakkumondo) 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. In his first appearance in Turkey, Jean has his first werewolf transformation when Little Boy riddles him with a barrage of bullets. 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.

She first participates in Romania for an assignment with Yu and the others to investigate what Trident agents were doing in the country. 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.

Oboro is called on by the ARCAM Corporation to infiltrate a Neo-Nazi faction in Egypt. His cover is responsible for helping Yu and Suzuko Kawahara neutralize Kutheimer's operations in Egypt. Oboro later participates with Yu in a mission to Iraq to protect Sister Kate, who had the Apocrypha of Rockis, which cultists from the Magier Heunri Balez wanted to use in conjuring demons. 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.

Iwao later appears in Romania as part of a Trident taskforce to eliminate Yu and other Spriggans. Although Larry Markson orders the destruction of the medieval fortress used to lure the Spriggans in, Iwao comes into the rubble and rescued Yu, showing that he has a sense of honor. He is later placed in charge of the SS Eugenio E, which is secretly transporting the Ark of the Covenant. After encountering Yu again, the two join forces once again to see what the Ark had to offer and to ensure the safety of the civilians when Sidewinder retrieves the Ark.

Nearing the end of the series, Iwao is targeted for termination alongside Yu, Jean Jacquemonde, and Bo Brantz by COSMOS forces.

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. Bo later encounters Yu, Tea Flatte, and Yoshino Somei in the secret cave where the Vajrayana was kept. However, when the Vajrayana explodes due to psychic overload from the Adolf Hitler clone, the cave is destroyed and Bo is one of the few survivors.

Realizing that he has no place to go, Bo joins Trident where he forms a steady alliance with Iwao Akatsuki. On the SS Eugenio E, he fights with Yu for the last time before teaming up with him to save the passengers. Nearing the end of the series, Bo teams up with Iwao to fight off COSMOS after the two are targeted for termination by Trident.
