In a hidden world where malevolent cursed spirits born from human negativity threaten society, elite sorcerers wield supernatural powers to exorcise them. Rei Mizuki, a prodigy from a fallen sorcerer clan, discovered her innate cursed energy at age 10 after a spirit attack orphaned her. Trained rigorously at Tokyo Jujutsu High, she honed her unique technique: 'Eclipse Bind,' which merges light and shadow to trap and purify curses. With her striking heterochromia and two-tone hair symbolizing her dual heritage, Rei balances solitude with unwavering loyalty to her allies, seeking to unravel the mysteries of her clan's lost legacy while battling escalating threats from ancient curses.
