OVA
Description
Airi Kashii attends Keishin Academy as a sixth-grade student in Class 6-C and serves as the center for the school's girls' basketball team, wearing jersey number 7. She stands 168 cm tall, a height significantly above her peers and even exceeding some high school students, which causes her distress and tears when mentioned. Her physique includes a well-endowed figure, contrasting her reserved and sensitive personality.

Her family history includes height and athleticism; her father and brother are tall and muscular, while her mother is described as voluptuous and above average in height. Her brother, Banri Kashii, is a recognized local amateur basketball player who exhibits overprotective tendencies. The family operates a gym or sports club.

Airi initially joined the basketball club to spend time with friends rather than pursue athletic ambition. Despite her physical advantages for basketball, her height complex initially hindered her performance. She received the nickname "Prismatic Bud" from Touko Hatano, reflecting her timidity and the contrast between her presence and gentle nature. Additional fears include aquaphobia, stemming from childhood trauma, and a noted aversion to cockroaches.

On the court, her height enables effective rebounding, shot-blocking, and close-range shooting. Early struggles saw her positioned as a small forward to de-emphasize her center role, conflicting with her insecurities. Training with assistant coach Aoi Ogiyama helped her gradually overcome these issues, improving her confidence and skill utilization. She evolved into a face-up center, leveraging her size to draw defensive pressure and create opportunities for teammates. This development was integral to the team's "One Center, Four Shooter" offensive strategy, where her role as a strong center facilitated spacing for perimeter shooters.

Her relationships with teammates, particularly Tomoka Minato, Maho Misawa, and Saki Nagatsuka, are central to her character; she values these friendships deeply and draws support from them. Subaru Hasegawa, the team's coach, aids her athletic growth, though accidental comments from him occasionally complicate her feelings due to her shy nature.

Airi's exact height remains unspecified in the series' official records as she missed school physical examinations due to illness, though visual comparisons confirm her stature. Her development across the series shows progression from self-consciousness to a more assured player, though her fundamental sensitivity persists.
