How Did a Certain Cursed Spirit Manipulator Become the Six Eyes' Familiar?!

A teacher from a certain technical college went on a business trip and accidentally entered another world. He stood to the side, munching on melon seeds and watching the commotion. Then a thought suddenly occurred to him. The next second, the person reporting to the First Assistant of Hell disappeared. A certain curse user was about to tell his current boss about his plans to reform Hell when he looked up and saw a familiar face he had not seen in a long time. "You're my shikigami now, Suguru~" As soon as the teacher finished speaking, the person opposite him vanished. On the other side, the Assistant of Hell said, "All right, Suguru. Let's continue discussing what we were talking about." The teacher stared at the empty space before him, stunned. Where had his Suguru gone? He was just that big! Before long, the Assistant appeared with the curse user, holding a sheet of paper. "Sign this and become an employee of Hell, and I'll hand him over to you." He pulled the curse user in front of the teacher. The teacher: "..." To sign or not to sign? * Pairing: Gojo x Geto. POV: Unknown.
