In a world where quirks determine the fate of heroes and villains alike, Seraphine Blanchet is a seemingly fragile and delicate first-year student at U.A. High School. On the surface, she is quiet, polite, and angelic — the most beautiful girl in her class, with long white hair, pale blue eyes, and an ethereal presence that draws attention wherever she goes. What no one realizes is that her quirk, Divine Heal, is one of the most powerful support abilities in the country, capable of restoring any injury — even life-threatening ones.
