the older brother

izumi midoriya was young when her brother left her and her family. the family was loving and caring but her brother was more of the parental figure than anyone else to her. though after he left they were never the same. Izumi brother just before he left told her one thing. " izumi come here. i have a necklace for you. if you ever feel like your in a bad situation just hold the necklace and call my name and i will come to you where ever you are." and just like that after he told her this he left and was never heard for years. and now izumi is in ua high and is wondering when she will see her brother again.
