Katsumi Tominaga hasn't seen anyone in the jujutsu world for nearly six months. With the pleasure of being sent on a rare, long-term mission, Katsumi is days away from closing the case- until esteemed sorcerer Megumi Fushiguro finds her, sent on his own mission by Satoru Gojo- their former instructor- to bring her back. Yuji Itadori is in trouble. She's the only one who can help. At least, that's what Gojo says is the case. But no one can really know what's going on in his head, can they?
