Kakeru Tengenji, a red-haired Leo with crimson eyes and a stature of 175cm, navigates Ayanagi Gakuen’s high school division as a musical department candidate after transferring from vocal studies. Born August 11 under blood type A, his kabuki lineage defines him—a childhood spent onstage cultivated regal poise and a sharp hierarchical worldview, fueling blunt critiques of those he deems unworthy. Beneath his aristocratic veneer lies unexpected tenderness: he adores cats, dotes on his hidden dorm companion Tavian (a black cat whose care includes daily water rituals), and once faced rumors of clandestine romantic liaisons debunked when classmates traced mysterious noises to his feline interactions.

Privilege and precision shape his habits—traditional Japanese meals, exclusive sips of family-brewed coffee, and a fast-food-free existence until a first-year incident. Academically unmatched, his report cards laud genius intellect yet chide his reluctance to collaborate. Though he claims no flaws beyond impatience for "boors," childhood isolation among adults left him socially adrift until Team Otori’s camaraderie, sparked by their earnest search for Tavian, nudges him toward tentative bonds.

His relationships oscillate between friction and fragile respect: initial disdain for Hoshitani Yuta melts into admiration for the latter’s tenacity, while rivalry with Tsukigami Kaito simmers with unspoken acknowledgment of mutual skill. Misread affections—like Nayuki Toru mistaking cat whispers for romantic murmurs—and explosive clashes with Ugawa Akira over team honor reveal layers beneath his frosty exterior.

Quirks punctuate his past: a childhood photo of him in a girl’s kimono, destroyed after a tantrum; dorm room 205’s car-accessed solitude; alternate-universe incarnations as athlete, underworld figure, or service professional. Though growth softens his edges into a team-oriented performer, his tongue remains as sharp as his self-assurance—a kabuki scion balancing legacy with the slow thaw of connection.
