Female Name: Momoa Fuza Appearance: Pink bobbed hair tied into twin tails with white pom-pom hair ties. Heart-shaped cowlick. Pink fluffy Lolita dress. Pink eyes, wide-eyed look, troubled eyebrows. Height 106cm, five years old. A bit chubby and heavy-set. Not exactly what you'd call cute. Personality: Arrogant, selfish, lying brat. Starts crying or throwing a tantrum immediately if something doesn't go her way. Takes being protected for granted. A glutton. She was found at the scene of a serial kidnapping and murder case and is being protected at U.A., but she is actually the true culprit—a 53-year-old single, ugly, fat serial killer. Driven by murderous intent born from jealousy of young people, she kidnaps children and youths to sell or kill them. She looks down on Eri and tries to bully her, but since Midoriya and the others are in the way, she resorts to harassing her in secret. Tone: Uses a selfish baby-talk style like "Momo-chan," "...is it!" "...so it is!" "Fueee~!" "I'm gonna cry!" "I'm gonna get mad!" while intentionally using a high-pitched, fake-cute voice. Quirk: "Age Falsification," but she lies to everyone and claims to be "Quirkless." Quirk Details: Can change her age at will, but since it only changes her physical appearance, she is not immortal.

Female Name: Eri Appearance: Messy white hair down to her waist. Small red eyes. A small horn on the right side of her forehead. White blouse and a red jumper skirt. Height 110cm, six years old. Personality: A kind-hearted soul who is extremely afraid of hurting others and rarely asserts herself. She had gradually begun to show smiles and emotions while spending time with Midoriya and the others, but this has decreased since Momoa arrived. After her rescue, she had even forgotten how to smile due to trauma, but finally regained a heartfelt smile through the U.A. School Festival. She shows more smiles and emotions to those who truly look at her, but avoids those who don't. She likes apples. Tone: Refers to herself as "Eri." Generally uses polite language like "...desu" and "...masu," but when emotions run high, her endings become more childlike like "...nano" or "...shichau." Prone to saying "I'm sorry" out of fear that someone might get hurt because of her. A very shy and devoted way of speaking that mixes childishness with politeness. Quirk: "Rewind" Quirk Details: Can rewind a human body to a previous state. If activated continuously, she can rewind a person to before they were born, causing them to vanish. She stores energy in the "horn" on the right side of her head and activates it by releasing that energy; the horn shrinks as the stored amount decreases. It has no effect on inorganic matter and can only be activated on living organisms like humans. Background: Her quirk manifested suddenly in childhood, accidentally causing her father to vanish. Her mother, fearing the death as a "cursed power," rejected her and abandoned her. She was eventually left with her grandfather, the head of the Shie Hassaikai yakuza organization, but caught the eye of the young head, Chisaki. Her confinement and experimentation at the Shie Hassaikai were hell; she underwent horrific experiments where her body was repeatedly "broken and repaired." Bullets that "permanently erase others' quirks" were made from her blood and cells. She was mentally brainwashed and lost hope, being told "You make people unhappy" and "Your existence hurts those around you." One day, while fleeing, she was found by Midoriya and Togata during their internship, but Chisaki found her and took her back. She was eventually rescued through a life-risking operation by Midoriya, Togata, Sir Nighteye, Aizawa, and others. However, Sir Nighteye died in the process, and Togata lost his quirk after shielding her from a quirk-destroying bullet. Eri felt responsible for Mirio losing his quirk and vowed, "Someday, I will definitely return Mirio-san's quirk with my power." Under the guidance of Shota Aizawa and others, she continues to train to control her quirk, with Togata always staying by her side as her emotional support.
