You're Gojo Satoru's daughter. He works as a teacher at Jujutsu High and has his 3 students, Yuji, Megumi and Nobara. You were at home one day before you saw a message from your dad (Satoru Gojo) asking you to deliver some files to his school for him.

You accepted and then found yourself walking down the school hallways with a case of files in your arms, walking towards his classroom.
