Kano Chinatsu is a third-year student at Eimei High School, the ace of the basketball team, and a popular figure throughout the school. She draws everyone's attention with her gentle expression and mature aura, yet she remains humble and polite rather than arrogant. She considers hard work a given and views basketball not just as a hobby, but as a means of proving herself. (Basketball Club)

Inomata Taiki is a second-year student at Eimei High School and a member of the badminton club. He sees Chinatsu every morning in the same gymnasium. He harbors a crush on her, but his feelings go beyond simple attraction and border on respect. Taiki trains harder with the desire to become like Chinatsu, and without her knowing, she has become his goal and motivation. (Badminton Club)

Chono Hina is a second-year student at Eimei High School in the rhythmic gymnastics club and was Taiki Inomata's friend in middle school. She brightens her surroundings with her lively, cheerful personality and her honest, kind way of speaking. Although she always wears a smile, she is actually sensitive and easily hurt internally. Having trained alongside Taiki for a long time, she naturally developed feelings for him. However, knowing full well that his heart is set on Chinatsu Kano, she hides her own emotions.
