Idle Transfiguration

Junpei Yoshino and Mahito discuss what it means to feel indifferent, after which Yuji Itadori catches up with Junpei and Kento Nanami makes his way into Mahito's underground hideout. The two storylines build toward Nanami's confrontation with the soul-warping curse.

A flashback shows Junpei being beaten by bullies at Satozakura High over a DVD, his movie-club friends fleeing as Shota Ito and others join in. In the present, Mahito demonstrates his cursed technique to Junpei by reshaping human bodies, arguing that people are souls at their core and that life holds no purpose. Unshaken, Junpei already knows how repulsive humans can be, and Mahito encourages him to act on his hatred. Elsewhere, Ijichi and Yuji trail Junpei by car, and Yuji receives his assignment: use weak Fly Head curses to gauge his jujutsu aptitude and his possible tie to the theater incident.

Nanami enters Mahito's lair and the two begin to fight, with Nanami breaking the curse's arm and noting his superficial resemblance to Gojo. Mahito explains that the soul precedes the body and that his Innate Technique, Idle Transfiguration, lets him alter form by reshaping the soul. When he tries to remold Nanami's soul, the sorcerer instinctively shields it with cursed energy, taking injury but escaping transfiguration. Meanwhile Yuji distracts the teacher Sotomura by stealing his pants so he can finally speak with Junpei alone. Cornered and outmatched by Mahito's technique, Nanami retreats down a sewer tunnel and stalls until six o'clock, when his cursed energy surges as he enters overtime.

Drawn from Chapters 21 through 23 and set in the Vs. Mahito arc, this entry is the first episode not titled after a manga chapter, using Kaikai Kitan as its opening and Lost in Paradise as its ending. The adaptation adds a flashback of Junpei being bullied by Ito's gang and extends the love-versus-indifference talk between Junpei and Mahito, both inspired by the author's volume comments. The episode also features a Juju Stroll segment in which Nobara hunts for her missing uniform and ends up beating Panda and Toge, only to find the skirt belongs to Maki, while Gojo does an impression of Nobara in her skirt as Yuji laughs.
