Ok look. I know this sounds kinda gay, but that ninja has a nice ass.
Your shock is that no one knows your name? What about the fact that your fist touched his balls? Maybe they don't know your name because you kill them with one punch, and the ones you don't kill are too terrified to speak.
This was a well written episode. The way how the villains being bald connected with Sonic meeting Saitama and Saitama learning that no one knows him. Also a pretty cool intro for one of the best characters: Mumen Raider.
