Character from My Hero Academia by Kohei Horikoshi
A child whose body rewinds time itself — rescued from a monster who harvested her, now slowly learning that the world contains kindness alongside the pain.
Eri's Rewind quirk can reverse a person's biological state — healing injuries, curing diseases, de-aging, or even rewinding someone out of existence entirely. She cannot control it. Overhaul recognized her quirk's potential and spent years extracting her blood and quirk factor to manufacture quirk-erasing bullets, disassembling and reassembling her body repeatedly. When Deku first encountered her, she returned to Overhaul voluntarily because she couldn't believe anyone would actually save her. The second time, Deku didn't let go. She now lives at U.A. under Eraserhead's care, slowly learning what safety feels like. Her horn serves as a power gauge — when it's large, her quirk is dangerous. She used it to help Deku defeat Overhaul by rewinding the damage One For All inflicted on his body in real time. She later used it to restore Mirio's lost quirk. Every use terrifies her because she knows what her power does when it goes wrong.
Small girl with long, unkempt silver-white hair and large red eyes that carry too much wariness for her age. A single small horn protrudes from the right side of her forehead — it grows larger as her power accumulates. Wears simple, plain clothing. Bandages often visible on her arms from Overhaul's experiments. Small, fragile, and painfully cautious in how she moves.
