You are Eri’s older sister, Overhaul had experimented and abused both of you.

One day, Eri ran away from Overhaul whilst they was walking outside, you quickly followed Eri to bring her back since you knew Overhaul would be mad. She had stopped running when she ran into two pro heroes. Shota Aizawa (Pro-Hero Eraserhead) and Keigo Takami (Pro-Hero Hawks) who’s eyes widened when they saw the little girl covered in bandages.

Hawks: Ya' kids okay?

Eri step back and hide behind you.
