Bujū, a Makemono—a hybrid of beast and demon introduced in the franchise’s third installment—begins as a violent brute raiding human settlements, earning the moniker “Chōjin of the East” from those who believe him linked to a divine prophecy. His fearsome reputation attracts Caesar, a warlord ruling post-apocalyptic Tokyo, who imprisons him to weaponize his strength. During captivity, Bujū escapes alongside Alector, Caesar’s deceased daughter resurrected as an android. He demands intimate favors in exchange for granting her freedom beyond her father’s tyranny. His path shifts upon encountering the Kyo-O, an infant prophesied to annihilate the Chōjin. Assuming guardianship, Bujū’s hardened demeanor softens into empathy, transforming him from mercenary to protector. His coercive alliance with Alector evolves into a fraught partnership marked by mutual dependency and gradual understanding, complicating their survival in a collapsing world. Though initially defined by brutality, Bujū’s bond with the Kyo-O sparks a moral reckoning, casting him as an unlikely guardian amid apocalyptic strife. His journey bridges savagery and compassion, influencing clashes between humans, demons, and Makemono. Exclusively tied to the third OVA series, his arc unfolds in a shattered society where interspecies conflict and societal decay test his role as both destroyer and reluctant redeemer.
