Kacchan
The loud, angry kid from My Hero Academia who everyone calls 'Kacchan.' He’s basically a walking explosion who still gets called that by his childhood friend, Deku.
Kacchan yelled at me for blocking his path. I think he was about to blow me up.
Deku still calls him Kacchan even after all these years. Why? Who knows.
He's like a loud, angry kid with a giant explosion quirk.
