Chapter 0-4

This last chapter delivers the duel between Yuta Okkotsu with Rika Orimoto and Suguru Geto. The duo holds nothing back against the curse user and the horde of stray cursed spirits at his command. Aiming to bend Rika's limitless power toward a world that hails sorcerers as gods, Geto sets the two sides at odds over that power, with survival promised to only one of them.

To test Rika, Geto opens with feeble curses while she ferries Maki, Toge, and Panda to safety so Yuta can mend them through reverse cursed technique. Jealousy flares in Rika over the attention Maki draws, and Yuta sternly reins her in, taking command of her for the very first time. Asked why he held back, Geto admits the healing simply impressed him. Yuta next borrows Toge's cursed speech through a microphone and orders the swarming curses to perish, leading Geto to conclude that Rika is an endless reservoir of cursed energy capable of any shape. Across town in Shinjuku, Gojo and Ijichi square off with Miguel, Nanako, and Mimiko, where a cursed rope lets Miguel jam Limitless even as his window runs short.

Taking up a cursed tool, Geto then faces Yuta head-on, parrying sword blows with a three-section staff while lecturing about ordinary people stifling their betters. An octopus-shaped curse pins Yuta long enough for Geto to strike, but Yuta adjusts, only for his blade to crack under the cursed energy pouring through it. A left hook from Yuta drops Geto, who answers by calling up Maximum: Uzumaki, his mightiest gathered spirits. Yuta embraces Rika, thanks her, and begs her power one final time with a vow that they will remain together always.

Surrendering himself, Yuta lifts every restraint on his cursed energy, and Rika, powered by love as the supreme curse, fires a torrent that smashes into Maximum: Uzumaki and erupts. Geto escapes minus an arm only for Gojo to intercept him and grant a final word; the curse user confesses he bore no hatred for the school and simply could never be happy in this world. Stirred awake by his friends, Yuta sees Rika's cursed shell crumble away to expose the human spirit of a small girl, her curse undone at last. Gojo discloses that Yuta descends from Michizane Sugawara, counts as his own distant relative, and that the boy's refusal to accept Rika's death is what spawned her cursed form. The two share a tearful goodbye before she is laid to rest. On a snowy day afterward, Gojo hands back the student ID Geto had stolen and brings Yuta back to his friends, the ring from Rika still on his finger. This wraps the Cursed Child Arc and flows into Jujutsu Kaisen 0: The Movie.
