Five years, 250 chapters, and ten million copies later, Kouji Miura’s Blue Box (Ao no Hako) has reached its final page. Chapter 250 landed in Weekly Shonen Jump Issue #33 on July 13, 2026, concluding one of the most quietly beloved manga serializations in recent Jump history. If you have been reading, today is that bittersweet last chapter. If you have been waiting, the complete story is now there for you.
Five Years, Ten Million Copies, One Final Chapter
Blue Box kicked off in April 2021 with a deceptively simple premise: Taiki, a first-year high school student training hard as a badminton player, develops feelings for Chinatsu, a basketball prodigy who happens to move in under the same roof. Kouji Miura built something genuinely warm from there — sports discipline, teenage awkwardness, and slow-burn romance woven tightly together across the Jump pages for over five years.
The series hit 10 million copies in circulation, a milestone that puts it comfortably in the higher tier of Jump’s modern roster. It never traded in the flashy power-scaling that dominates the magazine, and that restraint was exactly what made it resonate with its audience. Singapore and SEA fans who have been following along on Manga Plus can read the final chapter there now, free of charge — Shueisha makes the latest chapters available globally through the platform.
Anime Season 2 Arrives on Netflix This October
The manga ending does not slow the anime train. Blue Box Season 2 premieres on Netflix on October 4, 2026, announced at AnimeJapan 2026 back in March. Production has shifted to studio Electric Circus under new director Daisuke Sako, taking over from Season 1’s team at Telecom Animation Film. Series composition writer Yuko Kakihara and character designer Miho Tanino are back, so the visual and storytelling feel should stay consistent with what Season 1 established.
Where to Read and Watch Blue Box Now
With the source material now complete, Season 2 will be adapting manga chapters that have a known, finished ending — which is actually a good position for an anime to be in. The production team knows exactly where the story goes.
If you want to read ahead of the anime, the full run is on Manga Plus (Japanese; free globally) and the Viz/Shonen Jump app (English). Season 1 is already on Netflix, and Season 2 follows on October 4. For those new to the series, you have got roughly three months to catch up — which, at 25 episodes, is genuinely manageable. For everyone who has been here since 2021: it has been a good five years. Check out our manga and anime coverage for more on what is airing this season.
