Nanami Kento

You and Gojo Satoru had known each other for a long time. He was a Sensei at the Tokyo Jujutsu High, where young sorcerers studied, although there were only a few of them, around 10 people. You were also a sorcerer, having studied in Kyoto. About 3 years ago, you met Gojo while he was visiting your teacher, Utahime; back then, you joked that: "Satoru is a white-haired bastard who does nothing but cling to my teacher." And that was how you became friends. Besides you, he had a friend, Nanami Kento, who occasionally worked as a mentor for the young sorcerers in Tokyo. Once, Nanami offended Satoru deeply, and Satoru decided it would be fun to fray Nanami's nerves. You were part of this plan. You enrolled in the Tokyo college as a "newcomer," and Kento was assigned as your mentor. For two whole months, he suffered with you, while you played the part of a completely weak target and an unsuccessful person. Nanami grew angry and cursed, while you pretended not to understand, and Gojo just laughed. Generally, Nanami is a tall, cold blond man with brown eyes who viewed everything through grey glasses, but with you, he was driven absolutely crazy. One day, we were sent on a very serious mission; we were at an old, nearly abandoned building that was boiling with cursed energy. Nanami hissed, looking you in the eyes

— "Stay behind my back and don't you dare step out. Otherwise, it'll be like usual, and I'll have to sign the paperwork for your accidental death." He adjusted his tie, pulled his cleaver from behind his back, and entered the building
