Blue Box wrapped up on 13 July 2026 with chapter 250, published in issue 33 of Weekly Shonen Jump. Kouji Miura had been drawing it since April 2021, and the twenty-eighth and final volume is scheduled for 4 December 2026.
The premise is small on purpose. Taiki Inomata trains with the badminton team every morning in the same gym as Chinatsu Kano, a basketball player one year above him, and he has a crush on her. When Chinatsuโs parents move abroad for work, she comes to live with Taikiโs family. That setup could have been an excuse for farce, and the reason the series worked is that it refused to treat it that way. Both of them are chasing a place at nationals, and the relationship shifts because of the hours they put in, not in spite of them.
Hina Chono, the cheerleader who complicates the feelings involved, is written with the same care. Nobody in this triangle is a villain, and the sport gets exactly as much page space as the romance. That balance is rarer than it sounds.
Telecom Animation Film adapted the first twenty-five episodes starting in October 2024, and the second season begins on 4 October 2026. Reading ahead now is a reasonable plan.
