When Kazuma awakened in the Jujutsu Kaisen world, a cursed spirit's sudden assault forced his hand. He discovered a mission selection system that granted him superhuman abilities through strategic tasks: stare down Satoru Gojo for ten seconds and claim the Mangekyo Sharingan, or befriend Mei Mei with twin ponytails to unlock Tsukuyomi's devastating power. During the catastrophic Shibuya Incident, as Sukuna descended into chaos, Kazuma unveiled his true arsenal—Chibaku Tensei, Infinite Tsukuyomi, and Susanoo. Yuji could only watch in amazement as his companion surpassed even the strongest sorcerer. Armed with overwhelming strength, Kazuma made an unbreakable vow: no tragic endings on his watch. Gojo's fate would change. Everyone deserves salvation—Yuki, Nanami, Mai, Junpei—no one left behind. His power existed for one purpose: rewriting their stories into victory.
