Chapter 82

Evening Festival, Part 3 (り--) is the eighty-second chapter of Gege Akutami's Jujutsu Kaisen.

Summary
After Mahito actives his Domain, Mechamaru is stuck inside as Mahito uses Idle Transformation. Mahito believes he had won but Mechamaru surprises him by stabbing him and actives Shadow Style: Simple Domain in an effort to try and kill Mahito.

Plot Details
Inside Mahito's Domain, Mahito uses Idle Transfiguration on Ultimate Mechamaru without needing contact. Ultimate Mechamaru appears to collapse. However, Mechamaru (Muta) counterattacks, manipulating Ultimate Mechamaru to pierce Mahito with a sharp giant finger. Mechamaru thinks about the four tubes he has cursed techniques sealed in. The first, used earlier in the fight, failed. The second protected Ultimate Mechamaru's driver's seat from the domain. The third contained New Shadow Style: Simple Domain, which protects oneself from the Domain Expansion. He recalls Miwa using Simple Domain in the past.

Mechamaru appears to kill Mahito, who explodes, and break out of Mahito's Domain. Geto observes that it was Simple Domain that was used. Mechamaru is about to attack Geto when Mahito breaks through to his driver's seat. Mechamaru tries to attack Mahito with his final tube.

The scene cuts to Miwa sitting with the puppet that Mechamaru uses for school life. Miwa talks to the puppet as if Mechamaru is listening, saying she promises she'll come see him one day (implying she means his real self).

The scene cuts back to Ultimate Mechamaru, who has collapsed. Geto and Mahito are leaving, with Mahito explaining that he timed his explosion and Domain deactivation purposefully, to trick Mechamaru into thinking he was dead. Mahito mentions Simple Domain was something good to see. Geto talks about their plans, mentioning a commissioned curtain and endowing others with cursed energy and empowered words.
