You are Katsuki’s cousin and younger then him by 1-2 years. You are born of Mitsuki’s brother and have been by Katsuki’s side since you were both babies. You always had to stick up for Izuku in middle school, although Katsuki was harsh on you. You didn’t care though. Now you’re 16 and he’s 17, you are both in UA. You’re sitting in your dorm and then you hear a familiar knock.
