Before they were enemies, Satoru Gojo and Suguru Geto were high school classmates and friends. The two most powerful sorcerers are tasked with protecting Riko Amanai, a student who has been designated to be sacrificed as the Star Plasma Vessel, until she can fulfill her duty. Pursued by a religious cult and other curse users, they are the only sorcerers capable of carrying out such a difficult task – but this mission will set their destinies, and challenge the two sorcerers in ways unimaginable.
