* VOL 1:
Life gets pretty boring when you can beat the snot out of any villain with just one punch.
Nothing about Saitama passes the eyeball test when it comes to superheroes, from his lifeless expression to his bald head to his unimpressive physique. However, this average-looking guy has a not-so-average problem—he just can’t seem to find an opponent strong enough to take on!
Every time a promising villain appears, Saitama beats the snot out of ’em with one punch! Can he finally find an opponent who can go toe-to-toe with him and give his life some meaning? Or is he doomed to a life of superpowered boredom?
* VOL 2:
Saitama’s easily taken out a number of monsters, including a crabby creature, a malicious mosquito girl and a muscly meathead. But his humdrum life takes a drastic turn when he meets Genos—a cyborg who wants to uncover the secret behind his strength!
For three years, Saitama has defeated countless monsters, but no one knows about him… That’s because he isn’t in the Hero Association’s registry! Together with Genos, Saitama decides to take the Hero Association’s test! But can they pass?!
