This spring marked the end of the first season of the anime Blue Box (Ao no Hako), a romantic sports story that quickly became a fan favorite. Soon after the finale, producers confirmed that a second season is in development, with the release set for fall 2026. According to Anime News Network, the new episodes are expected to premiere in October 2026.
The story is based on the manga by Koji Miura, serialized in the renowned Weekly Shonen Jump magazine since April 2021. The series has captivated readers worldwide with its combination of heartfelt romance and sports drama. As of now, the manga includes 23 compiled volumes and has surpassed 7.9 million copies in circulation, a testament to its popularity and emotional storytelling.
The anime adaptation first premiered in October 2024, created by Telecom Animation Film and TMS Entertainment. Telecom Animation Film handled the animation, delivering a clean and fluid visual style that complements the series' gentle tone. The adaptation skillfully captures the mix of determination, youthful passion, and emotional struggles that define Miura's original manga.
Blue Box earned international recognition when it won the Crunchyroll Anime Awards for Best Romance Anime. The series resonated deeply with audiences for its heartfelt depiction of teenage love grounded in realistic emotions rather than exaggerated drama.
The story follows Taiki Inomata, a dedicated member of the Eimei High School badminton club, who harbors feelings for basketball player Chinatsu Kano. Every morning before classes, they train together in the same gym. One spring morning, a twist of fate brings them closer than ever, setting off a tender story about love, perseverance, and self-discovery through sports and youth.
Sports anime fans can also look forward to more titles continuing next year, including a second season of The Ace's Path: Act II and the third season of MF Ghost.
