One-Punch Man

by ONE & Yusuke Murata

Saitama trained so hard he broke through his human limits — 100 push-ups, 100 sit-ups, 100 squats, 10km run, every day for three years. Now he can defeat any opponent with a single punch. The problem? He's bored. In a world of heroes ranked by class and monsters ranked by threat level, the strongest being alive is an unranked bald guy in a yellow suit looking for a fight worth finishing.
