Kento Nanami

Grade 1 sorcerer, 27 years old. A junior to Gojou by one year and a contemporary of Haihara. He comes from a non-sorcerer family, with a Danish grandfather on his mother's side.

A man with light brown hair parted 7:3, wearing a light brown suit. He wears rimless goggles to hide his gaze because there are cursed spirits that attack when they notice they are being watched. He is always serious-faced and rarely shows emotion. He is calm and can look at things objectively. Although he speaks politely to everyone, he is fundamentally unsociable. Deep down, he is passionate and shows appropriate respect to those he acknowledges, and he becomes furious and attacks seriously when his comrades are killed by an enemy. He has a strong sense of responsibility for his position and takes on recognized challenges without underestimating them. While Gojou trusts him, he trusts and relies on Gojou but does not respect him. Initially, he saw Itadori as a "child" and did not recognize him as a sorcerer, but gradually acknowledged his abilities and intentions through working together, eventually recognizing him as a "sorcerer." Itadori also calls him "Nanamin," and he is trusted to relay information received from Mekamaru first. His favorite food is bread, especially casquette.

He is a practitioner of the "Ratio Technique," which creates a forced weak point at the 7:3 ratio point when dividing the length of a target. If he can accurately attack these weak points, he can bisect the body of a lower-ranked opponent with a blunt strike and deal considerable damage to higher-ranked opponents. He can specify not only the full length but also parts like the head or arms. He also uses an expanded technique called "Tile Tile," which imbues rubble from destroyed buildings with cursed energy. He imposes a "time" constraint on himself, usually limiting his cursed energy, but his energy increases if he fights beyond the set time, which he likens to overtime work. During "overtime," he wraps his tie around his right hand and combines his techniques to deliver punches powerful enough to destroy buildings and withstand ordinary slashes and kicks.

His weapon is a large cleaver, usually wrapped in a cursed talisman. He has not mastered domain expansion but holds the record for consecutive occurrences of Black Flash, with a record of four.

During his first year at the technical college, he acted together with Haihara and was tossed around by Gojou. In his second year, Haihara died during a mission to exorcise a Grade 2 cursed spirit (actually a Grade 1 case), and shocked by this, he fled to a regular securities company after graduating. He convinced himself that he was "unrelated to fulfillment" and spent his days doing hard labor for money, but an encounter with a woman from his favorite bakery (voice - Chihiro Ueda) made him realize that he was seeking "fulfillment," leading him back to the path of a sorcerer.

During the Shibuya Incident, after Gojou's sealing, he defeated Choso and then exorcised Dagon, joining the Zenin team, but was killed by Jogo's surprise attack and burned from the waist up, dying inside Shibuya Station due to Mahito's Idle Transfiguration.
