One-Punch Man (Vol.31) - One

In One-Punch Man (Vol. 31), the balance between heroes and monsters reaches a breaking point. The Monster Association launches its most devastating assault yet, eliminating S-class heroes one after another in a brutal display of power.

But amid the chaos, a new “savior” emerges—King, the so-called strongest man alive. Calm, fearless, and mysterious, King faces the monstrous threat head-on... even though fans know his terrifying secret: he’s not actually strong at all.

As the world teeters on the edge of destruction, Saitama, the hero who can defeat anyone with a single punch, remains detached from the spectacle—until destiny calls him back into action. The tension builds, the humor sharpens, and the explosive artwork by Yusuke Murata makes every page a visual storm of energy and emotion.
