Lost Cat

Eager to feel useful at last, Saitama accepts a Hero Association job in a cafe before learning what it involves, only to be handed the task of tracking down a runaway cat. Genos meanwhile meets a different staff member who confesses that he lost a Mysterious Being he had raised as a pet and wants it quietly destroyed, with the surrounding blocks cleared under the cover story of a pollution survey.

Saitama hunts for the cat Torako using a vague sketch and grudgingly teams up with a staff member's young daughter, comforting her when she breaks down in tears. Genos follows a blood trail to two beaten A-Class heroes, Peach Terry and Heavy Kong, before the Demon-level Grizzly Nyah drops on him from the walls. As Saitama bluffs his way past the guards Tanktop Tiger and Tanktop Black Hole into the sealed zone, Lightning Genji and Stinger wound the creature, only for a far larger Grizzly Nyah to rise up behind them.

Genos realizes the monster he fought was the offspring, and that the mother had given birth after slipping away. When the enormous Nyah corners the little girl and Torako, Saitama steps in, shields the cat, and kills the beast with ease. He reflects that the errand wore on him more than any monster fight and doubts he suits hero work, a feeling driven home when Torako scratches him and he snaps at it.
