One-Punch Man

Mumen Rider has always been the underdog hero—no super strength, no flashy moves. But when he discovers he can amplify the willpower of any hero nearby, his true potential awakens. Now a despair-feeding monster threatens the city, and Genos is overwhelmed by his own rage. Should Mumen boost Genos’s power and risk his friend losing control, or let him fight alone? In a world that measures strength by destruction, Mumen must decide what it truly means to be a hero.

A routine monster fight ends with an odd discovery: a note tucked under a rock, predicting Saitama's first defeat to the exact second. He laughs it off—until small coincidences start stacking. When he finally examines the handwriting, his blood runs cold. It's his own. From the future. Now he must race against a ticking clock, dodging every battle and deadline, to break a prophecy that feels more certain with each passing hour. Can he outsmart a future he himself wrote?
