Kaiju No. 8 anime to end with Conclusion Arc as Narumi spin-off announced
The anime adaptation of Naoya Matsumoto’s Kaiju No. 8 will officially wrap up the series with a newly announced “Conclusion Arc.”
This production update was revealed during the franchise’s stage presentation at Jump Festa ’26 on Saturday, confirming that the story of Kafka Hibino will be adapted through to its end.
In addition to the main series finale, the panel announced a new anime short titled “Narumi no Heijitsu” (Narumi’s Weekday).
This spinoff project will focus on the popular Captain Gen Narumi, presumably offering a glimpse into the daily life of the strongest anti-kaiju combatant when he is not on the battlefield.
The original manga by Matsumoto concluded its serialization on Shueisha’s Shonen Jump+ service earlier this year on July 18.
The anime adaptation has seen a rapid release schedule since its debut; the first season premiered in April 2024, followed by a compilation film, Kaiju No. 8: Mission Recon, which saw theatrical screenings in North America.
The second season of the television anime recently premiered on July 19, continuing the trend of real-time worldwide streaming on the X platform alongside its broadcast.
This announcement aligns Kaiju No. 8 with several other major franchises wrapping up their runs following news from Jump Festa ’26.
The weekend event has confirmed a trend of conclusions and climaxes; the final cour of Dr. Stone: Science Future is set to air in April 2026, while Bleach: Thousand-Year Blood War will conclude with its final part, “The Calamity,” in July 2026.
The upcoming anime calendar is heavily populated with high-profile releases.
April 2026 will see the premieres of Kill Blue and Akane-banashi, alongside the return of One Piece for the Elbaph Arc.
Other major updates included the confirmation of a 2026 return for Black Clover and a second season for Blue Box in the fall.
Looking further into the future, 2027 will feature third seasons for both DAN DA DAN and Mashle: Magic and Muscles.
Production plans were also solidified for a second season of Sakamoto Days, ensuring fans have a steady pipeline of content for their favorite Shonen Jump series over the next two years.
