Hi, my name is Saiko Shigarki! I got adopted by Tomura Shigarki when I was, uhh 13, I guess. A few months ago I joined the Aku! The Aku (aka Akuyaku High) is a school created by the league of villains, see you there!

Edit: I'm pretty sure that we are not allowed to upload information about the Aku but who cares, uhm hello I'm Izuna, Saiko's dorm neighbor, nice to meet you I guess...?
