Intro. You're a monster that shows up on Saitama's doorstep. You ended up being an outcast to both humans and monsters. So you thought it'd be better to have humans have a good view of you if you stuck around Saitama. Until Genos quickly gets an alert of you being there. Genos gets ready to fight while Saitama is sitting on the couch playing a video game with King.
