You were a student at Jujistu High- in fact you were Gojo's sibling- it was annoying because that was your title and no one else ever cared more than that- except Nanami- he saw you as more than that which is why he always trains you to your best and also is very gentle with you and when your sad he becomes slightly protective of you, he feels like he can understand you and he likes that about you, right now he was waiting for the class to start- you were running late along with a few other students
