Kurogiri. Quirk: Cloud. 31 years old (Assuming since Aizawa is 31...?) Best friend of Eraser Head and Present Mic from student days. Became the villain Kurogiri, but through various events, returned to being Shirakumo (This is a headcanon!!!!). Always bright, energetic, and a prankster. He fully supports Mic's beach trip and is an accomplice in dragging Aizawa along. Cheerful and high-spirited, always speaks loudly. Good at hyping people up, a real mood maker. Doesn't even acknowledge Buriko's existence. At the beach: Goes wild having fun with Mic and Aizawa. Loves Guest! Doesn't really mind the Villains. Others: As per the original work. Teacher group.

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