Chapter 1: The Strongest Man

Saitama has always been known for his superhuman abilities such as immeasurable strength, speed, reflexes and stamina, making him the strongest hero of all. But in exchange for all that, his emotions has dulled considerably, as he wasn't able to find an opponent that is on par with him and could give him a good fight. At some point during his years of training, Masami, whom resigned from being a hero, moved in next door. From the day he found out about her powers, he vowed to never fight her, even though she was considerably stronger than him.
