Archbishop leads the R-Wings faction in Yanagihara City, driven by a mission to spread his self-proclaimed faith. He identifies the Yanagihara Flame Birds (YFB) as the primary obstacle to his ambitions and employs ruthless tactics, fueled by his followers' resolve, to eliminate this opposition. His aggression peaks when he fires a gun indiscriminately after an incident causes him to "overshoot his goal." Dora intervenes, halting the violence and redirecting Archbishop's hatred entirely toward himself. Consumed by vengeance, Archbishop fixates on destroying not only Dora but anyone associated with him, signaling his accelerating descent into instability and madness.

His eccentric appearance and fanatical actions cement his role as an antagonist in street-level clashes involving the YFB and allies of Hayato Narita. This culminates in a perilous cafe confrontation where Archbishop's recklessness endangers bystanders, including Naru Ohtori who narrowly escapes harm.
