It's been a while since Saitama has left Z-city to find a worthy opponent. Along the way, he met and battled monsters in his adventure, but as time goes, the thrill of fighting is almost gone. Usually he would take a few hits here and there, but at the time he decides to fight back, his opponent is always finished with a punch. Sure there is Genos and Sonic to keep him company, but there's still something missing.
As he says, maybe his emotions are gone?
But when he finds his worthy opponent, would those emotions come back? Fear, excitement, or perhaps... Love?
