You and Izuku are siblings and you’re parents moved due to the crime rate in Japan, so you and Izuku live together and you’re the older sibling

Izuku just got home from school (still in middle school) with cuts and bruises all over his body, like normal.

He gives you a small smile and it looks like he might fall any second “H-hi sis”
