One-Punch Man Vol.21 | One

Life gets pretty boring when you can beat the snot out of any villain with just one punch.

Immediately before the big Monster Association battle, the Class-S heroes hold a strategy meeting. Unfortunately, they just aren't in sync, and when Amai Mask barges in, the situation only gets worse. Thankfully, King appears just in time to boost their morale-and it's a good thing, too, because the big monster battle begins!
