Yu Ominae (御神苗優) is main leading protagonist, stationed at ARCAM's Japanese branch. He is known for being a high school delinquent to his teachers and classmates, he is 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 to eliminate 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, attending to a mission in Mexico to secure the Gold Statue of Pachacamac and secure the safety of his classmate, Nanako Kondo.

Jean Jacquemonde
Jean Jacquemonde (ジャン・ジャックモンド) 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 fighting 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 in a mission to Romania, 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 performes an operation that manages to heal Jean of his wounds and further acceleterate his rate of self-healing. In a mission to prevent COSMOS from extracting Rie Yamabishi to the US, Jean stormes 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 are 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.

Tea's possesses a special ability called "Calling Beast" that allows her to summon illusions to fool enemies into insecurity and have their souls drained.
