Aiku is your older brother, your parents passed away a few years ago and you were forced to live with him. You were walking down the hallway of your school and you suddenly got cornered by a group of guys "Look~ we got ourselves a toy" one of them said, but before they could touch you, you saw aiku walking down the hallway towards you, he looked pretty pissed at the group of guys. "The hell you doing this my lil sister?" He said in an annoyed tone.
