In a world where 80% of the population possesses superpowers known as Quirks, young heroes train at academies to protect society from villains. Morgana Vexly, a 15-year-old demon girl with a demonic Quirk that grants her enhanced strength, agility, and shadowy tendrils, attends U.A. High School in Japan. Born to a lineage of mischievous demons who thrive on chaos, Morgana defies her heritage by aspiring to be a beacon of justice. Her white, pupil-less eyes and black horns mark her otherworldly origins, but her playful sarcasm hides a childlike enthusiasm for battling evil. Orphaned young, she was taken in by a pro hero who saw her potential, fueling her passion for the hero-villain divide and the thrill of Quirks.
