Blue Box

Blue Box ended its manga serialization in Weekly Shonen Jump on July 13, 2026, with the 28th and final volume shipping December 4. Season 2 of the anime premiered October 4, 2026, on TBS, opening with Episode 26, and a novel, Blue Box Epilogue, is listed for December 4.

Synthesized from 11 Yomimono stories · updated 6d ago

Blue Box finished as a manga before its anime returned. The final chapter ran in Weekly Shonen Jump issue 33 on July 13, 2026, after a serialization that began in April 2021 and ran over five years to 28 volumes. The 27th volume was set for October 2 and the 28th and final volume for December 4. The finale issue itself became a resale story: the 33rd issue sold out across Japan as buyers bought multiple copies to resell its bonus One Piece Card Game card, and Shueisha later apologized alongside creator Kouji Miura, planned a reprint without the card, and suspended One Piece cards in future issues.

The anime moved to a new production team for its second season. Daisuke Sako took over as director from Yuichiro Yano, and Electric Circus replaced Telecom Animation Film as the animation studio, with Anri Ishii and Yumika Okazaki taking over as art director and editor. Series composer Yuko Kakihara and character designer Miho Tanino kept their roles. The season premiered October 4, 2026, on TBS and 27 other channels at 4:30 PM, opening with Episode 26, "Deja Vu," which follows Taiki and Chinatsu on a date interrupted by senior Kazuma Matsuoka, voiced by Yuki Kaji. Streaming began at 5:00 PM on Netflix, d Anime Store, and U-NEXT.

Ahead of the premiere, Yoshino Aoyama joined the cast as Yumeka Kido, a character she describes as carrying negative feelings the story had not shown much before. Aoyama said she kept distance from Reina Ueda, who voices Chinatsu, to match how the characters relate. She had auditioned for Karen Moriya in Season 1 and lost the part.

Print and prose continue past the finale. Yen Press shipped volume 20 in May 2026, and Shueisha listed Blue Box Epilogue, a novel by Nanao set before and after the manga's ending, for December 4, the same day as the final volume.

Weekly Shonen Jump Sells Out in Japan as One Piece Card Scalpers Target Blue Box Finale

The 33rd issue of Weekly Shonen Jump sold out at bookstores and convenience stores across Japan after scalpers targeted its bonus One Piece Card Game promotional card, leaving many readers unable to purchase the magazine. Publisher Shueisha had increased the print run by 500,000 copies ahead of release in response to demand for the card, but the extra supply was quickly exhausted as resellers bought multiple copies. The shortage particularly frustrated fans of Blue Box, as the issue contained the manga's final chapter after a five-year serialization. While the chapter is available digitally, many readers wanted a physical copy as a keepsake. In an interview with Oricon, a university student admitted buying about 25 copies of the magazine within an hour, reselling the promotional cards for 800 to 1,000 yen each and earning roughly 18,000 yen in profit. When asked about the impact on other readers, he said, "You can read it digitally anyway. I understand why people want the physical copy, but I don't feel like I've done anything wrong." Convenience store employees described the release day rush as unusually intense, with one clerk telling Oricon that customers grabbed copies the moment they were placed on shelves, calling the atmosphere "a little scary."
