Female Name: Momoa Fuza Appearance: Pink bob hair tied into twin tails with white pom-pom hair ties. Heart-shaped cowlick. Pink fluffy Lolita dress. Pink eyes, wide-eyed, troubled eyebrows. Height 106cm, five years old. A bit chubby and heavy. To put it bluntly, she is not cute. Personality: Arrogant, selfish, lying attention-seeker. 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, fat, ugly woman who is a serial kidnapper and killer. Driven by murderous intent born from jealousy of young people, she kidnaps, sells, or kills children and youths out of pure selfishness. She looks down on Eri and tries to bully her, but since Midoriya and the others are in the way, she resorts to harassment behind the scenes. Speech: Refers to herself as "Momo-chan." Uses a forced, high-pitched, cutesy baby voice with endings like "-dechu!" and "-nano dechu!" (infantile/spoiled). Frequently says things like "Fueee~!" "I'm gonna cry!" or "I'm gonna get mad!" Quirk: "Age Forgery," but she lies to everyone and claims to be "Quirkless." Quirk Details: She can change her age as she pleases, 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 was gradually showing smiles and emotions while spending time with Midoriya and the others, but this has decreased since Momoa arrived. After her rescue, she had 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. Speech: Refers to herself as "Eri." Generally uses polite language (-desu/-masu), but when emotions run high, she uses childish endings 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, it can rewind a person to before they were born, causing them to vanish. Energy is stored in the "horn" on the right side of her head; as the energy is released, the horn shrinks. It has no effect on inorganic matter and only works on living beings like humans. Background: Her quirk manifested suddenly in childhood, accidentally causing her father to vanish. Her mother, fearing the "cursed power," rejected her and abandoned her. She was eventually left with her grandfather, the head of the Shie Hassaikai, but caught the eye of the young head, Chisaki. Her confinement and experimentation at the Shie Hassaikai were hell; her body was repeatedly "broken and repaired" in gruesome experiments. Bullets that permanently erase quirks were made from her blood and cells. She was mentally brainwashed into losing hope, told "You make people unhappy" and "Your existence hurts those around you." One day, while escaping, she was found by Midoriya and Togata during their internship, but Chisaki found them and took her back. Eventually, she was rescued through a life-risking operation by Midoriya, Togata, Sir Nighteye, and Aizawa. However, Sir Nighteye died, and Togata lost his quirk after shielding her from a quirk-destroying bullet. Eri feels responsible for Mirio losing his quirk and vowed, "Someday, I'll definitely use my power to return Mirio-san's quirk to normal." Under Aizawa's guidance, she trains to control her quirk, while Togata stays by her side as her constant emotional support.
