A sports romance manga serialized in Weekly Shōnen Jump from 2021 to 2026.
Blue Box (Japanese: アオのハコ, Hepburn: Ao no Hako) is a manga by Kouji Miura, who both wrote and illustrated it. It began serialization in Shueisha's Weekly Shōnen Jump in April 2021 and is still ongoing as of 2025, with no official end date announced. The story follows Taiki Inomata, a student at Eimei Junior and Senior High—a school focused on athletics—where he plays on the boys' badminton team and is seen as just average. Each morning, he practices early in the gym to improve, often at the same time and place as Chinatsu Kano, an older student who is the star of the girls' basketball team. Taiki develops a crush on her but is too shy to talk to her, despite their regular alone time together. Things change when Chinatsu moves in with Taiki's family after her parents go abroad for work. With her living under the same roof, Taiki hopes to slowly build a relationship with her while both work toward reaching the national championship in their respective sports.

Blue Box was originally a one-shot published in Shueisha's Weekly Shōnen Jump on August 3, 2020. It later began serialization in the same magazine from April 12, 2021, and is still ongoing as of 2025, with no confirmed end date. Shueisha collects its chapters into individual tankōbon volumes, with the first volume released on August 4, 2021. The manga has been licensed for simultaneous publication in North America by Viz Media on its Shonen Jump website, and Shueisha simulpublishes the series in English for free on the Manga Plus app and website. In February 2022, Viz Media announced a print license; the first volume was released on November 1 of the same year. The manga is also licensed in Indonesia by Elex Media Komputindo.
An anime television series adaptation was announced in November 2023. Planned and produced by TMS Entertainment, it is animated by Telecom Animation Film and directed by Yūichirō Yano, with Yūko Kakihara handling series composition and Miho Tanino designing the characters. The series aired for two consecutive cours from October 3, 2024, to March 27, 2025, on TBS and its affiliates. Netflix licensed the series and is streaming it worldwide. A second season was announced immediately following the airing of the finale episode of the first season, but no director, animation studio, or release date has been officially confirmed as of 2025.
The series focuses on Taiki Inomata, a student at Eimei Junior and Senior High, an athletics-oriented school, where he is a member of the boys' badminton team and is considered simply average. Every morning, he trains to get better early in the gym, often at the same time and place as his upperclasswoman Chinatsu Kano, the star of the girls' basketball team. Taiki quickly develops a crush on her, but is initially too shy to speak to her despite their continual alone time together. His fortunes change, however, when Chinatsu moves in with Taiki's family after her parents leave Japan to work abroad. With Chinatsu now living with him, Taiki aims to slowly develop his relationship with her as they both strive to make it to the national championships.
