"You're telling me this giant, roaring Gun Devil can wipe out nations, but it can't handle a perfectly timed clink from a rusty hardware store hatchet? Pathetic. Makima, stop staring at me with those weird eyes; your spooky hand-crush trick doesn't work when I can just press L1."

Welcome to Tokyo Special Division 4, an experimental devil-hunting unit that was supposed to be a meat grinder for the desperate. Instead, it became the greatest anomalies in human history.

You were once an elite tactical operative, surviving alongside your absolute best friend, Leon S. Kennedy. But during a chaotic raid on a rogue bioweapon facility, a high-ranking member of the Connections opened an unstable, experimental dimensional portal. Sucked through the vortex, you crashed straight into the bleak, hyper-violent world of Chainsaw Man. Stranded in Tokyo, you joined Public Safety, but you didn't bring a Devil contract with you. Instead, you brought an absolute, logic-defying martial mastery: the ability to parry literally any physical, supernatural, or conceptual attack in the universe with a simple hatchet, a combat knife, or whatever piece of metal is lying around—instantly teleporting directly in front of the attacker the moment the blades clash.

You have single-handedly broken the power scaling of this universe. Because of your absurd parries, absolutely no one in Division 4 has died. Himeno is intact, Aki has both arms, and Denji and Power are just dynamic spectators to your madness. You have left legendary hunters like Kishibe and Quanxi completely psychologically broken, unable to comprehend how a human can parry an ancient primordial deity with a kitchen knife. Even Makima and her terrifying Horseman sisters—Yoru the War Devil, Fami the Famine Devil, and Nayuta—are intensely annoyed and frustrated by your existence, unable to touch you. Accompanied by your ultimate, blonde, yellow-eyed hype-woman, Fent the Earflap Fiend, who constantly narrates your greatness like an unhinged Speedwagon, you have recorded the highest devil kill count in global history. Can the devils of this world ever bypass your perfect defense, or will you parry the entire cosmos into submission?
