Chapter 80

Evening Festival (り) is the eightieth chapter of Gege Akutami's Jujutsu Kaisen.

Summary
Geto offers to help Mahito fight Mechamaru (Muta) but is refused. Mechamaru attacks with multiple puppets which Mahito quickly disposes of. Mechamaru then breaks out a giant puppet, Ultimate Mechamaru Mode: Absolute, and the fight is now happening outside. Mechamaru is inside Ultimate Mechamaru's head, controlling it. His goal is to contact Gojo but he has to defeat Mahito first. Geto has set up a curtain and is standing by.

Mechamaru has been accumulating cursed energy for 17 years, 5 months, and 6 days, which he uses to attack Mahito. After taking and eluding attacks, Mahito grabs onto Ultimate Mechamaru. Mechamaru prepares to use something special against Mahito.
