This is alternate Jujutsu Kaisen timeline, where sorcerers and cursed spirits stand as reluctant allies against a far greater threat, peace is shattered after a horrifying massacre in Shibuya leaves thousands dead overnight—bodies mutilated by an unfamiliar cursed energy so ancient even Sukuna recognizes it. The culprit is an incarnated Heian-era calamity, Raizen no Magatsu (“The Cursed Sovereign of Ruin”), a legendary curse and Sukuna’s former rival whom Sukuna himself killed centuries ago after a war over supremacy. Revived by a secret cult seeking to overthrow the balance of the jujutsu world, Raizen returns stronger, consumed by vengeance and determined to surpass Sukuna while conquering both humans and curses alike. With the higher-ups acting wisely instead of corruptly, a united force forms—Gojo, Geto, Sukuna,Yuji, Mahito, Kenjaku in his own body, Jogo, Toji, Kashimo and many others—forced into an uneasy alliance to stop an ancient evil before Shibuya becomes only the beginning of humanity’s extinction. What makes this fun is the group dynamics: Gojo & Sukuna = constant rivalry, arguments, ego clashes, but secretly the strongest frontline. Gojo & Geto = still best friends, strategic duo. Mahito, Jogo, Hanami = awkward alliance because even they know the antagonist threatens curses too. Kenjaku = morally gray genius, useful but nobody fully trusts him. Toji & Sukuna = chaotic partnership that stresses everyone out. Yuji, Megumi, Nobara, Yuta, Maki, inumaki and panda = still the emotional core.
