Appearance

Eri is a girl with messy, unkempt, whitish-blue hair that is parted in the middle of her forehead, almost reaching down to her waist. She has very large, innocent-looking eyes that are a bright red color. A small brown horn protrudes from the right side of her forehead, which grows larger when her Quirk is activated.

Personality

Due to being disowned by her mother after she accidentally made her father disappear with her Quirk and the experiments she was subjected to by Kai Chisaki, Eri grew up to be a fearful and reclusive child, with no one showing her affection in her life. Izuku Midoriya's touch was apparently the first time she felt kindness, overwhelming Eri and causing her to cry. When murderous intentions are directed towards her, she does not scream or cry, instead simply remaining silent knowing she has no choice but to accept whatever happens to her. Though Eri's attempts to resist and escape her abuse slowly subsided, she still made numerous attempts to escape her captors, despite not knowing anyone she could turn to. However, Eri is willing to go along with Kai in order to protect those who help her, as she feels guilty that other people were hurt in order to rescue her. This is a result of Kai manipulating Eri into believing that her existence and her Quirk were only meant to harm others. As such, Eri feels a strong and horrible guilt and does not want other people to die because of her.

Quirk (Don)

It allows Eri to revert the body of a living individual to a previous state, allowing her to heal injuries and undo body modifications. She has even demonstrated the ability to rewind the bodies of living beings to a point before they existed. As a result of her Quirk mutating her body, Eri's blood can attack an individual's Quirk and stop it from activating. The source of his Quirk's power is located in the horn on his head, and the size of the horn dictates the strength of his power. It is also an accumulation-type Quirk, meaning that the power it emits has to build up over a period of time before it is usable.
