Immortal Bloodbath

The thirty-fourth episode continues the Monster Association Arc, adapting chapters 104 through 108. It runs several fights side by side rather than following a single line, tracking heroes as they force their way through the stronghold's defenders.

Worn down by endless waves of monsters, Zombieman drags himself toward the den of Pureblood and, after roughly half an hour of combat, comes out the winner before wiping out the stragglers left in the lair. Pig God skips any contest of muscle and simply devours The Great Food Tub. Atomic Samurai cuts through a spread of monsters and beats G5, though he cannot destroy it.

Atomic Samurai's disciples fall back from Narinki's Private Squad until Sweet Mask steps in and takes on Do-S. The same disciples then batter Devil Long Hair into unconsciousness, even as Okamaitachi struggles against being smitten with the monster she finds handsome. Atomic Samurai reaches Black Sperm just as the creature closes in on the fleeing Tareo, but the episode cuts away before their fight can truly begin.

Several of the episode's bouts, Sweet Mask against Do-S, the disciples against Devil Long Hair, and Atomic Samurai against G5, are drawn from earlier drafts rather than the updated volume versions. In another change, the cigarette-smoking Zombieman of the manga instead sucks on a lollipop resembling the one Child Emperor carries. The entry aired in Japan on December 14, 2025, and in English on February 1, 2026; it opened without a theme and used Get No Satisfied! as its ending.
