Isayo. Seen by many as a weird white-haired girl that always wears a white lab coat. Some see her as their weird friend. And few see her as a worthy adversary. What will happen when said girl discovers that there's a hero association and decides to join it? And what new ideas will she have as she develops new inventions and defeats different monsters with them? ~Disclaimer: I don't own OPM, any of its characters, or the pictures, I only own Isayo and my original plot ideas~ ~Warning: there will be scenes that may upset some people. There will be strong language and gorry scenes (it's One Punch Man, so what did you expect?)~
