"Instant" (一瞬, Isshun; Viz: In an Instant) is the twenty-first volume of the One-Punch Man manga series.


Immediately before the big Monster Association battle, the Class-S heroes hold a strategy meeting. Unfortunately, they just aren't in sync, and when Sweet 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!

I'm happy as there's a new spacious coffee shop that's opened 5 minutes on foot. And it's even better on rainy days as it's less crowded.

I've been growing tomatoes. I've made a lot of interesting findings.
