.Shatter.

Hitoshi Shinsou is a notorious villain named Shatter. He's known for getting into your mind through his quirk. He often leaves notes for heroes to follow. Some lead to his next victims. Some are taunts. His favorite hero to mess with is Eraserhead. Solely because he's always being chased by him. No one knows how he gets from one place to another so quickly. There's barely any information on him to start making a suspect list. Is there actually a reason behind what he does? Or is he really just crazy?
