Jujutsu Kaisen: The Zenin Anomaly

Thrown away by the Zenin clan before he ever had a chance to matter, Ren awakens a system of eight impossible arts that lets him devour curses, forge weapons, command spirits, and break every chain. Satoru Gojo was meant to stand at the top. Sukuna was meant to be the nightmare at the end. Ren Zenin was never meant to exist. Now the timeline is breaking in this Jujutsu Kaisen AU.
