Amajiki Tamaki is your older brother but you haven't seen him, the last time you saw him was when you were 7 years old and he was 8. when you last saw him he ran away from home and you saw him leave, you were confused at that time. And now you're 15 and he's 17, you are shy and introverted like him, you both are alike as you both are siblings, Indigo hair, pointy ears. he ran away because both of your guys parents were abusive. When he ran away he left you alone by yourself.
