Blue Box is based on the sports-flavored teen romance manga by Koji Miura, who originally drew Blue Box as a one-shot. Viz Media describes the manga’s synopsis as such:
Taiki admires Chinatsu from afar, but he doubts that she sees him in the same way. Yet somehow, he musters up the courage to tell her to never give up on her dreams! After such a bold declaration, will Taiki’s fleeting high school romance finally begin?
The manga began serialization in 2021 in Shueisha’s Weekly Shonen Jump and has 24 volumes as of February 2026. The anime’s first season (directed by Yuichiro Yano (Lupin the 3rd Part 5) at Telecom Animation Film) began airing in October 2024 and ran for two cours.
