He's a Mummy, Isn't He?

Horrified to see Mr. Dris stab Okarun, Momo flings a nearby traffic cone at Mr. Dris and dives toward Okarun, helping him dodge the follow-up. Okarun tells her to abandon him, but when she refuses he has her crouch and cling to him so she won't fall. Recalling that Momo trained in ki from childhood, he asks her to perform her old ritual, suspecting she can handle the Oni Club better than he can. After parrying Mr. Dris' next strike, Okarun passes her the club; she cannot trigger its bat form, yet to his shock it swells once back in his grip, letting him cleave the charging mummy in two.

When the club shrinks, Okarun has Momo repeat the spell, and as it lengthens again he understands her ki is pouring through their contact into him and the weapon. The edge it gives still leaves him fretting over the mummy's regeneration. Darkness then swallows the field, hiding Mr. Dris, until the sound of his bicycle lets Okarun block another swing just in time. Momo tells him to kill the club's glowing release form, since it works like a beacon, and after the next parry Okarun realizes Mr. Dris navigates by echolocation, judging distance from his bike's noise because his mask blinds him.

Armed with that, Momo plots to weaponize the very nature of his mummified body. When he lunges next, the mummy is duped by a decoy she set, giving her the opening to snatch one of his bandages. Okarun steadies her, and together, singing, they unwind his wrappings; laid bare, the mummy's ancient skin instantly rots and crumbles, exactly as Momo intended.

Carrying the date November 25, 2025 and not yet collected in tankobon form, this twenty-three-page chapter runs in the Six Curses Arc under the Ultimate Yokai Saga, between Chapter 217 and Chapter 219. Momo chooses to fight alongside Okarun rather than flee to Jiji, the Oni Club becomes a great sword through her ki ritual, and the duo defeat Mr. Dris by unwrapping him in the dark to rot his flesh.
