When Haruki transmigrates into the Naruto world, a blade-wielding ninja attacks without warning. Bracing for death, he's stunned as massive claws emerge from behind him, shredding his attacker in seconds. The terrifying visage belongs to Rika—the Queen of Curses from Jujutsu Kaisen, bound to his soul. The Cursed Spirit Mother Auxiliary System activates, revealing his new identity: Yuta Okkotsu. With this template comes access to legendary cursed spirits—Rika already secured, and the King of Curses Ryomen Sukuna awaiting awakening. Armed with Yuta's powers and a formidable ally in his cursed companion, Haruki must navigate the shinobi realm while unlocking the true potential of his cursed spirit arsenal. In a world of chakra and jutsu, curse energy becomes his greatest weapon.
