Set during the events of Jujutsu Kaisen shortly after Yuji Itadori’s apparent death at the Detention Center. The story follows the canon timeline closely. Everyone except a select few believes Yuji is dead. Instead of entrusting Yuji’s training solely to Nanami, Gojo secretly assigns Kaoru Ichizaki, one of Tokyo Jujutsu High’s youngest assistant instructors, to help train and supervise him in hiding until the Kyoto Goodwill Event.
