One-Punch Man Episode 31: Counterstrike
Heroes arrive in Z City but face a monster ambush. A-class aids while Gyoro-Gyoro watches the fight.
Full recap
The heroes arrive in **Z-City** and are immediately hit by a **sudden ambush from monsters attacking from all directions**. While the **A-class and lower-ranked heroes** fight on the ground as support members of the operation, **Gyoro-Gyoro** stays above the battlefield and watches the chaos unfold.
As the attack begins, the episode focuses on the large-scale battle rather than a single duel, showing the heroes forced into a frantic defense against the overwhelming number of monsters. The monsters’ surprise assault creates a situation where the heroes must split up and respond to threats coming from multiple sides at once, turning the mission into a full battlefield counterattack.
From above, Gyoro-Gyoro continues surveying the fighting, clearly treating the battle as something to observe and evaluate rather than join directly. The episode ends with the conflict still in progress, with the heroes struggling to hold their ground against the monster ambush.
