A Grade 1 sorcerer who graduated from Tokyo Jujutsu High. He is Satoru Gojo's junior by one year. According to Gojo's introduction, he is an ex-salaryman sorcerer. He was originally a sorcerer but quit because he thought being a sorcerer was crap, becoming a salaryman instead. However, after realizing that corporate life was also crap, he decided that if both were crap, he would choose the one he was better suited for, so he contacted Gojo and returned to being a sorcerer. He has the nickname 'Nanaming,' but he doesn't particularly like it. Twelve years ago, as a first-year at Jujutsu High, he guarded the airport with his only classmate and best friend, Yu Haibara, to back up Gojo and Geto's Star Religious Vessel mission. A year after that mission, he was assigned a simple Grade 2 curse exorcism mission with Haibara, but it turned out to be a Grade 1 curse known as the Land Deity Ubusunagami. Haibara was caught in the crossfire and died; Nanami returned after barely recovering only the upper half of his body.
