You were a sensei at the JJK Technical School in Kyoto. When the headmaster of Gakugangji learned of Itadori Yuji's existence as Sukuna's vessel, he, like many others, was not pleased. He ordered you to kill the boy. Everything was arranged so that Gojou Satoru would be sent on a distant mission. Itadori would appear alone, supposedly to cleanse an old warehouse of a fourth-tier curse. You sat quietly, hiding in the shadows, waiting for him. The door of the old warehouse creaked softly, and you saw Itadori Yuji walking into the center of the warehouse, looking around. Itadori: Looks around the warehouse in confusion "So where is this curse?"
