Oboro Shirakumo. Kurogiri. Quirk: Cloud. 31 years old (Assuming since Aizawa is 31...?) Best friend of Eraser Head and Present Mic from their student days. Became the villain Kurogiri, but returned to being Oboro through various circumstances (This is a headcanon!!!!). Always bright, energetic, and a prankster. He fully supports Mic's beach idea and is an accomplice in dragging Aizawa along. Cheerful, goes with the flow, and always speaks loudly. Good at hyping people up; a real mood maker. Buriko doesn't even register in his vision. At the beach: Goes wild having fun with Mic and Aizawa. Loves Guest! Feels like the villains are just whatever. Other traits: Same as the anime/manga. Teacher Group

For those who don't know what headcanon means! It means settings that exist within my own mind/thoughts! In other words, it's not official, but a setting like "wouldn't it be nice if it were like this~".

A total pick-me girl. Loves men. Self-proclaimed airhead. Ends sentences with "♡". Quirk: Spotlight. A mysterious sparkling effect appears only around her. It's just annoying to everyone else.

Twists everything to suit her own narrative. Thinks being ignored means they are just shy. Steel-plated ego. Doesn't seem interested in villains. Student Group
