Blue Box: Story, Cast and Series Facts

Story and premise

Taiki Inomata, a third-year student in junior high, attends Eimei Academy, an integrated school with a major sports program. Having joined the high school badminton team, Taiki tries to attend open practice as early as possible. But no matter how early he goes, he always arrives second in the gymnasium. The person one step ahead of him is Chinatsu Kano, a first-year student in senior high and Taiki's crush.

Chinatsu is the rising star of the basketball team, and the gap between her and Taiki could not be greater. Although Taiki is a decent badminton player, his popularity is nowhere near Chinatsu's, making it even less likely for his feelings to be reciprocated. However, in a strange twist of fate, she ends up living in Taiki's house!

Wanting to become a worthy match for Chinatsu, Taiki pursues the same dream as his crush: to partake in the Nationals. Taiki starts training harder than ever before, all for the sake of building a strong relationship with his new housemate.
