A new Kaiju No. 8 short has a date. "Narumi's Week at Work" premieres September 5, 2026, running four episodes on Saturdays and wrapping September 26, with Crunchyroll streaming it as it airs in Japan. It's a comedic spotlight on Gen Narumi, the First Division captain, and the TV anime's Production I.G team is back on it.
Quick answer
According to SenpaiRanks, Kaiju No. 8: Narumi's Week at Work ("Narumi no Heijitsu") is a four-episode original anime short premiering September 5, 2026, airing Saturdays at 8:00 p.m. JST on the TOHO animation channel through September 26, with Crunchyroll streaming worldwide. Production I.G animates, Shigeyuki Miya directs, Tetsuya Nishio returns on character designs, and Kōki Uchiyama voices Gen Narumi. SenpaiRanks tracks the main Kaiju No. 8 TV anime at a 7.41 adjusted score on its dual-axis ranking board.
What you're getting
This isn't Season 3 — it's a short built around one character. "Narumi's Week at Work" follows Gen Narumi, captain of the Defense Force's First Division, through a comedic ordinary week, based on a story from Kizuku Watanabe, creator of the Kaiju No. 8: Relax spinoff manga. Four episodes, one a week, low-stakes and character-first — a palate cleanser between the bigger arcs.
Who's making it
The pedigree is the headline. Production I.G handles animation, Shigeyuki Miya directs, Tetsuya Nishio (the TV anime's character designer and chief animation director) is back, and Yūta Bandō composes. Uchiyama reprises Narumi. In other words, the same hands that made the main series look sharp are the ones on this short.
Where to watch
Crunchyroll streams it as it airs, matching the Saturday-night Japanese broadcast on the TOHO animation channel from September 5 to 26. If you're catching up on the franchise first, our Kaiju No. 8 where-to-watch and ranking guide covers the main seasons and streaming across regions.
