Nao Inabe attends Aota Academy as a student and serves on the girls' volleyball team, specializing as a right front attacker. Her scoring ability ranks second only to the team's top scorer, Shou, making her a dependable source of points in matches. She stands 167 cm tall with red hair, violet eyes, and body measurements of 88-59-89 cm, featuring a distinctive mole. Typically seen in her team sports uniform, her fiery temperament mirrors her red hair, driving her competitive nature and sharp tongue. She openly confronts authority, directing pointed critiques at the arrogant captain of rival O-Ring Academy and occasionally at her own coach, Motoura. Despite these clashes, she harbors an underlying attraction to Motoura that influences her actions, such as when encountering him during her part-time job at a karaoke bar. Her straightforwardness extends to personal confrontations, where she voices opinions without hesitation. In the sequel "Kaette kita Court no Naka no Tenshi-tachi," she joins the team's training camp for the national tournament. She also appears in the spin-off "Court no Naka no Tenshi-tachi 2 ~Softball Hen~," confirming her participation in softball beyond volleyball.
