Blue Box Manga Concludes: Koji Miura's Sports-Romance Legend Comes to an End

As of June 2025, the highly anticipated Blue Box (Ao no Hako) series has officially come to an end. This manga, in which Koji Miura masterfully blended sports and romance, marked the close of an era by reaching a total of 10 million copies in print. As the final chapter was published in Shueisha's Weekly Shonen Jump magazine, the series reaching this point left fans both emotional and curious: Will the anime adaptation achieve the same success?
When the series first met readers with its debut chapter in April 2021, it drew attention as the first long-running project by young talent Koji Miura. The story focused on the love and rivalry between Taiki Inomata, who aspires to be a badminton star, and basketball player Chinatsu Kano. Miura quickly gained a large fan base with his character development and emotional depth, as well as his artwork. Realistic sports scenes and sweet adolescent romance made the manga one of the most unique examples of its genre.
The conclusion of Blue Box also marks the farewell of one of Weekly Shonen Jump's most successful new series in recent years. While the magazine experienced a void in the early 2020s with the finales of giants like Jujutsu Kaisen and My Hero Academia, Blue Box was one of the productions that filled that gap. The anime adaptation, announced in 2023, further increased the series' popularity. Produced by Telecom Animation Film and released in April 2024, the anime received acclaim both in Japan and on international platforms. With the manga's finale, whether there will be a second season of the anime remains uncertain for now.
Throughout the manga, Koji Miura handled his characters' sports careers and their relationships with each other with great care. Whether Taiki and Chinatsu reached their goals in the final chapter was a topic long debated among fans. Now that the series is officially complete, what readers are most curious about is Miura's next project. The end of the manga also opens the door to new series on digital platforms like Jump+. While Blue Box fans experience the feeling of completing the series, they are eagerly waiting for Miura to turn a new page in his career.
Finally, all volumes and spin-off materials of Blue Box are still on sale. If you haven't read the series yet, now is the time to complete it; if you have, don't miss the emotional closure brought by the final chapter. This unique story that melts sports and romance in the same pot seems likely to be talked about in the manga world for a long time to come.
