Azumi, one of three vice-commanders in the All-Stars University Team led by Alice Shimada, commands an American M26 Pershing tank adorned with a front-mounted yellow diamond. Her light brown hair and turquoise eyes complement a uniform of the team’s jacket and pencil skirt, distinctively omitting the standard hat, shirt, and tie—a choice that leaves her cleavage exposed even during chilly weather or covert missions.
As the de facto leader of the "Bermuda Trio" with Megumi and Rumi, she blends a hard-drinking, party-loving attitude with deep admiration for her commander’s charm, often voicing dismay when Alice contemplates transferring schools. Despite her raucous persona, she reveals tenderness, notably comforting teammate Hibiki Inatomi.
A BC Freedom Academy alumna, Azumi’s tactical prowess shines during the Ooarai match, where she directs seven Pershings and a Chaffee in flanking maneuvers and encirclements. She chases scattered foes through a theme park, enduring ambushes to eliminate a hidden StuG III, later aiding in neutralizing Saunders’ forces, the Tiger II, and T-34/85. Her Pershing falls to Miho Nishizumi in the final clash.
Off the battlefield, she balances part-time modeling with relentless yet fruitless efforts to refine her teammates’ deportment. Her cooking, subpar even among her trio, contrasts her social fervor—post-match, she revels with judges and peers, drink in hand.
Notably, her "-mi" suffix aligns with fellow vice-commanders, and she once helmed the All-Stars regimental headquarters. Her strategic actions in the film secure her team’s first elimination against Ooarai.
