The Curse Inside U.A. (MHA)

Long before heroes existed, the King of Curses, Ryomen Sukuna, was sealed away by ancient warriors. Centuries later, in the world of My Hero Academia, a U.A. student accidentally breaks the seal and swallows the cursed relic. Now the most dangerous demon in history lives inside a future hero—and the age of heroes may never be the same. Midoriya: "Heroes saves everyone!" Sukuna: "Then save them... from me!"
