Eri

Eri is a young girl that Chisaki claims to be the father of.

Appearance
She is a child with bandages all over her body. She has a small horn on the right side of her forehead and has long, choppy, unkempt hair.

Personality
She is a frightened little girl who doesn't want to take part in Chisaki's plans. Because of this, Chisaki considers her a "troublemaker".

She is however willing to let herself go with Chisaki in order to protect those that help her.

Synopsis
Eri was running down an alley away from Chisaki, mentally chanting she had enough of her treatment and wishing someone would save her. She bumps into Izuku and Chisaki catches up to them.

Quirk and Abilities
According to Overhaul, she is the key to his plan.

Overhaul
Similar to how he treats his members, Chisaki only values Eri for her use. However with certain members, like Chrono, Chisaki values Eri enough not to consider her to be disposable.

Eri is terrified of Chisaki. Her fear of Overhaul is strong enough to make her not disobey him when he gets serious.

Midoriya Izuku
He was the first person she bumped into when running away from Chisaki. She tearfully pleaded for him to not leave her alone with Chisaki and to help her.

Izuku was suspicious of Eri's unnatural treatment. Even though he was instructed to remain covert around Chisaki and despite the interventions of Mirio and Chisaki's rebuttals, Izuku desired to protect Eri.

When Chisaki took off his glove and revealed his killer intent, Eri immediately went back to him. Izuku was shocked and confused by her behavior. He wanted to reach out to her but was held back by Mirio. He could only look on in worry as she was taken away.
