A side story included in the booklet "Jujutsu Kaisen 0.5" that was given out at Japanese screenings of "Jujutsu Kaisen 0." The chapter itself was originally released a week prior to the movie's release as a promotion in Weekly Shonen Jump.

A manga booklet given out to movie attendees for *"Jujutsu Kaisen 0"*. It shows the daily lives of a few select characters.

The story takes place a one year before Itadori's time, focusing on his upperclassmen at Jujutsu High--Maki, Panda, Toge and Yuta Okkotsu (the MC). In Jujutsu Kaisen, we don't see Yuta, but other characters often make reference to him and the incidents that occur in this volume. Yuta's been brought in to Jujutsu High by Satoru Gojo because he's been cursed by his childhood friend, Rika. But this is no ordinary curse as she's classified Special Grade. And because of her overwhelming strengh, Yuta doesn't know how to control or use her. Meanwhile, Suguru Geto is out to get Yuta Okkotsu, specifically targeting Rika to add to his own collection of cursed spirits he controls, setting up a showdown with his best friend-turned-enemy, Gojo.
