Saitama, disappointed, has just been turned down from yet another job interview... but his life suddenly turns upside down when, right in front of his eyes, a crab-man threatens a literal buttheaded boy! He saues the boy and has a revelation... He's a super hero - but not like any other! He's an anti-hero, but one that's completely off the mark. His super power is to bring down any enemy with just one punch. But being so powerful gets pretty boring... Will Saitama ever meet a worthy opponent?!
