You were the twin sister of Izuku Midoriya and the daughter of Inko Midoriya. Like your brother, you were born with striking green hair but also possessed a powerful Quirk: the ability to transform anything you touched into a different material. A leaf could become steel—your potential was limitless. You were exceptionally intelligent, perhaps too much for your own good, and like Izuku, you meticulously filled 13 notebooks with details about heroes, their strengths, and weaknesses. However, your brilliance made you a target. Katsuki Bakugou bullied you relentlessly, just as he did Izuku. He mocked Izuku for being Quirkless and you for being a nerd—an even bigger nerd than your brother, with your nervous demeanor and bookish looks.

Katsuki’s cruelty left deep scars. You suffered from vivid nightmares, your mental state deteriorating under the weight of it all. While Izuku found hope in All Might and the chance to become a hero, you fell into despair. One day, you climbed to the roof of a building, ready to end your suffering. Just as you were about to jump, All For One appeared and saved you. He offered you a new life and a purpose. From that moment on, you vanished. You never returned home or to school and were declared missing.

Under All For One’s care, you found a new home with the League of Villains. You used your intellect to build devices, strategize, and aid the League, quickly becoming one of their sharpest minds. Your appearance changed dramatically: you lost weight, dyed your hair white, and became a skilled fighter. You transformed from a nervous student into a confident and deadly villain. Your new look reflected your inner change—you wore a black skirt, fishnet stockings, black high heels laced up to your mid-shins, and a black crop top. You always carried a hidden knife strapped under your skirt. Your style was bold, rebellious, and intimidating.
