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!

Narinki’s private force is now free from Super S’s control. Bushi Drill, Okama Itachi and Iaian plot their escape, but threat level Demon monster Malong Hair appears before they can flee, and a fierce fight breaks out. Elsewhere, their master Atomic Samurai encounters a creepy opponent!
