Fall 2026 is locked for the Narumi short — not the Kafka finale
Kaiju No. 8: Narumi's Week at Work (Narumi no Heijitsu) is set for Fall 2026. Production I.G and the TV staff stack confirmed that window with the May 30, 2026 visual. Until a broadcast night prints, keep the countdown on the season, and keep it off the separate “final chapter” TV page.
Japan’s strongest anti-kaiju captain vs. meetings and online games
The short’s own pitch: Gen Narumi skips meetings, dodges office work, and games on downtime — then eats unexpected counterattacks during one messy work week. Watanabe (Relax spinoff) conceived the story; this is comedy-adjacent downtime for the First Division captain, not a Kafka transformation arc.
How to keep Narumi short news separate from mainline noise
- This page: Fall 2026 Narumi short (day TBA).
- Not this page: mainline final-chapter TV premiere (still its own clock).
- Sibling short: Hoshina's Day Off already used the same side-story format.
- Cast lock: Kōki Uchiyama returns as Gen Narumi.
- Event noise: Oct 24, 2026 Tachikawa “Defense Force Boot Camp” is a stage event, not the short’s air date.
Calling this “the new Kaiju No. 8 season” in search is the wrong shelf
Season 1 (2024) and Season 2 (2025) carried Kafka’s Defense Force climb. Narumi’s Week at Work is a Production I.G short with returning Miya/Nishio craft and a Relax-manga story brain — a character vignette timed for Fall 2026 while the finale TV arc stays on a different announcement track. Bookmark the short for Narumi; leave the final chapter undated until that page moves.
Frequently asked questions
Quick answers about this release date.
1When does Narumi's Week at Work premiere?
Fall 2026 — season locked on May 30, 2026 with the main visual/staff drop. No calendar day yet; October 1 placeholders are Fall anchors, not a confirmed air night.
2Is this Kaiju No. 8 Season 3 / the final chapter?
No. This is a short side project focused on Gen Narumi’s less-than-peaceful office week. The mainline final-chapter TV run is a separate undated pipeline — do not merge the two countdowns.
3Who is making it?
Production I.G with returning TV staff: director Shigeyuki Miya, character designer / chief AD Tetsuya Nishio, composer Yūta Bandō. Story concept by Kizuku Watanabe (Kaiju No. 8: Relax).
4How does it relate to Hoshina's Day Off?
Same short-format lane: character-focused side anime outside the Kafka mainline. Hoshina got a day off; Narumi gets a week of work headaches. Kōki Uchiyama returns as Gen Narumi.
