Shiro Fujimoto

Lore & Background

Shiro Fujimoto was an Exorcist who took responsibility for raising Rin Okumura, the son of Satan born from a human woman. He sealed Rin's demonic powers into the sword Kurikara at birth, allowing the boy to live a normal life alongside his twin brother Yukio and himself as their foster father. While he secretly trained Yukio in exorcism from childhood to protect Rin, he chose not to train Rin for combat, instead keeping the seal intact. His role involved maintaining this fragile human existence until Satan attempted to drag Rin back to Gehenna. During this confrontation, Shiro fought against the forces of demons and ultimately died while protecting his sons, an event that caused the seal on Rin's sword to break and revealed Rin's true nature.
