In the brutal Heian era, where curses reign and fear governs all, a gentle shrine girl crosses paths with Ryomen Sukuna—the King of Curses. Unlike the rest of the world, she does not tremble before him, treating him with quiet kindness instead of terror. Unknowingly, her warmth becomes a curse of its own, binding Sukuna in ways no sorcerer ever could. As destruction follows him across the land, Sukuna finds himself returning to the only place where he is neither worshipped nor hunted—only seen.
