Description
Teruma Kamioka exhibits contrasting portrayals across media. In the anime, he is the "Two-faced B-Der," possessing a split personality. One persona is a kind, pious individual who runs an orphanage, working multiple jobs to support the children who affectionately call him "Teruma nii-chan." The opposing persona is a sinister, aggressive demon who revels in destruction, laughing maniacally and commanding foes to "Go to Hell!" Triggers for the demon include exposure to the Seven Deadly Sins, intense violence or evil presence, personal fears like heights or seasickness, and stressful situations like job scoldings. The kind persona reemerges upon hearing children's voices, feeling guilt, or receiving genuine kindness. Despite the demon's destructive urges, care for the orphanage children persists, even gifting them stolen B-Damans. His B-Daman is Sturm Griffon. He competes in tournaments such as the B-1 Crash Cup and the East VS West B-Battle Festival, eventually joining the Seven Legendary B-Ders to fight antagonists. By the anime's end, a pivotal confrontation reconciles his dual nature; the devil persona vanishes permanently, granting him the confidence to wield his B-Daman powerfully without transforming.
In the manga, Teruma lacks a split personality, depicted uniformly as gentle, religious, and kind. He frequently prays for forgiveness while serving as an assassin within the Evil Deity Organization, bearing their tattoo on his nape and hiding scars under long sleeves. Sent as a spy to infiltrate the Tamaga household and steal the protagonist's B-Daman under the guise of a helper, he defects after experiencing genuine familial warmth for the first time. His backstory reveals past abuse by higher-ranking members like Kyousuke Arasaki, who tormented him to "awaken the devil." Key moments include refusing to steal the B-Daman during a church battle and later infiltrating the Evil Deity's tournament. There, he sacrifices himself to shield the protagonist from a lethal attack, sustaining severe injuries. He survives and ultimately joins the Tamaga household, embracing a peaceful life free from his assassin past.
