第6章:Collapse and Oden: Shisan and Aki Inside a crumbling building the Muscle Devil smashes pillars and goads Shisan out of hiding. Aki fights wildly, Shisan's Gluttony-bound claws strike and become trapped as the Muscle Devil reveals the true snare — only to be decapitated by Aki's blade. After the rubble, awkward camaraderie and Makima's quiet orders send Shisan to room with Aki, and the chapter closes on a messy, warm meal at an oden stall.

第5章:A New Assignment — Muscle Devil on Kujawano Street Shisan, still dazed by Makima's unexpected gentleness, accepts bread and a place under her command before being fitted into a Public Safety uniform. He's assigned to Special Action 4 under Hayakawa Aki and leaps onto Aki's motorcycle to a demon assault on Kujawano Street. There, they encounter a towering Muscle Devil — a brutal chase and clash begin that forces Shisan and Aki to retreat into a ruined building as the devil pursues them.

第4章:Red Maw, Green Remedy Shisan is slammed and trapped by the flexible, brutal arms of the Zombie Demon as his regenerative Viridian Devil struggles to keep him whole. The Claw Devil and the Gluttony (Famine) Devil intervene in a savage ballet of tearing flesh and roaring hunger, turning the fight into an all-consuming purge. Exhausted and half-destroyed, Shisan collapses unconscious — only to be cradled and prodded awake by a calm woman with a braid who calls herself Makima.

第3章:Two Devils, One Eye Surrounded by a writhing horde and a towering corpse-mountain, Shisan's two contracted devils manifest: a green, regenerative aura and a colossal crimson claw. He pays the price—losing his right eye—to summon the claw and lashes out, mowing down hordes, but the Zombie Demon bites the claw and retaliates, leaving Shisan wounded and the true fight beginning. Blood, tooth, and smoke set the stage for a desperate duel: Shisan's fury versus the zombified boss that led him into the trap.

第2章:Debt, Deception, and the Corpse Mountain Shisan, a starving teenage demon hunter, is hauled into a black-suited crime boss's convoy and learns he's enslaved by a thirty-million debt. Lured into the countryside under the promise that a powerful beast will wipe away half his debt, Shisan and the gang find an apparently haunted, empty house where the boss's men suddenly turn on him. Surrounded by zombified hunters and a towering mound of corpses, Shisan is overwhelmed by a crimson claw — the setup reveals he was led into a trap to be consumed by the very 'zombie demon' he hunted.

第1章:Aisle of the Rat Demon A teenage freelance demon hunter, Shisan, wakes in a cramped apartment, hears a news report about demons, and goes out to buy instant noodles. A rat demon smashes into the convenience store — Shisan fights it off with reckless improvisation while his health pact heals him. As he lies bloodied, the looming gluttony demon briefly appears to devour the rat demon; an old boss calls with a new job offer.
