Jujutsu Kaisen: Kaigyoku/Gyokusetsu

Before Satoru Gojo became the strongest jujutsu sorcerer and Suguru Geto became his enemy, the two were classmates, partners, and friends who seemed almost untouchable. Their most consequential assignment is to protect Riko Amanai, the girl chosen as the Star Plasma Vessel, until she can merge with Tengen and preserve the balance of jujutsu society.

The escort turns into a deadly pursuit as multiple groups seek Riko's life and Toji Fushiguro, the feared Sorcerer Killer, enters the hunt. What follows tests more than Gojo and Geto's strength. The mission fractures their beliefs about the world they protect and becomes the point from which two inseparable friends begin moving toward radically different futures.
