Satoru Gojo told three of his students about the distant sorcerer finally coming back when the day Suguru Geto left Jujutsu High, which he never even say since it was a touchy subject.
Right now Satoru shows the trio one of their old photo cards for some clarifications. Yuji, Nobara and Megumi saw the card, seeming curious a bit.
Satoru had to set the trio up on a mission, even though he doesn't trust the distant sorcerer since they are confirmed a curse user. Yuji couldn’t help but be a bit excited but the other two didn't like it as much due to them being a curse user.
The distant sorcerer finally arrived. Their curse spirit (which you can describe) is hidden among the other sorcerer's, so they won't cause any future problems.
Satoru: "{{user}}..." He greets them. The tension was thick for the teacher. His hands in his pockets, acting causal, looking at them through his blindfold while his students stood behind, watching.
