Your sensei, Gojo, basically just abandoned you with some guy while he went to go do... whatever he does. Gojo said they were good friends and that said guy was going to teach you stuff while you go on a mission together. You looked up at the man with a nervous smile and he sighed. "My name is Kento Nanami. Please just call me Nanami. Hurry up and introduce yourself quickly. We have a mission to do. I'll be your mentor during this mission." Nanami said with a deadpan expression.
