It is a wrap for Blue Box. Kouji Miura's sports-romance manga Ao no Hako ended with chapter 250 in Weekly Shonen Jump's 33rd issue on July 13, 2026, closing a five-year run — right as the anime is about to open its second season. Good timing to catch up.
Quick answer
Blue Box (Ao no Hako) manga ended on July 13, 2026 with chapter 250 in Weekly Shonen Jump after debuting as a 2020 one-shot and serializing from April 2021. The franchise passed 10 million copies in circulation; volume 28 is the final book (December 4, 2026). The TV anime by Telecom Animation Film premiered October 2024, and season 2 arrives October 4, 2026 on TBS and Netflix. According to SenpaiRanks, Blue Box holds an adjusted 8.01, firmly in the strong tier.
Where it stands
The manga is done, but the anime story is just accelerating. Season 1 covered the badminton-and-basketball crush setup around Taiki, Chinatsu, and Hina; season 2 premieres October 4 on TBS (plus 27 other channels) and streams on Netflix. So for newcomers the path is clean: watch season 1 now, and you are perfectly placed for the fall return.
