‘Kaiju No. 8’s’ ‘Narumi’s Week at Work’ Episode 3 Release Date, Time, Trailer and Where to Watch

Gen Narumi is trading kaiju battles for something far more relatable, an overflowing inbox and a work week he clearly wishes he could skip. The short first surfaced back in December 2025 during Jump Festa 2026, and unlike the earlier ‘Hoshina’s Day Off’ special, this project stretches across a full month with four episodes running from September 5 through September 26, 2026.

Now episode three is on deck, and fans of the Defense Force’s most reluctant paperwork warrior are counting down the days. With two entries already out in the wild, the anticipation for this next chapter of Narumi’s very ordinary, very funny work life has only grown.

‘Narumi’s Week at Work’ Episode 3 Release Date and Time

The spinoff debuted on September 5 at 8PM JST on the TOHO animation YouTube channel, with the remaining three episodes scheduled to drop on September 12, 19, and 26. That puts episode three squarely on Saturday, September 19, following the same weekly Saturday night slot the series has kept since its premiere.

For viewers outside Japan, the schedule shifts slightly because of time zone differences, since the international rollout on Crunchyroll began a day earlier than the Japanese YouTube debut.

Kaiju No. 8, Narumi’s Week at Work began streaming internationally on Crunchyroll starting September 4, with new episodes arriving weekly across North America, Central America, South America, Europe, Africa, Oceania, the Middle East and CIS.

That one day gap between the Japanese YouTube debut and the international Crunchyroll rollout is fairly typical for simulcast anime, and fans tracking the series from abroad should expect episode three to land Friday, September 18, locally before the Saturday JST premiere catches up. Either way, the wait is short, and the format keeps each installment feeling like its own bite sized story rather than a rushed release.

Where to Watch the ‘Kaiju No. 8’ Narumi Spinoff?

Narumi’s Week at Work is airing for free on the TOHO animation YouTube channel in Japan, while Crunchyroll carries it in territories where the platform already streams the main ‘Kaiju No. 8’ anime. Both seasons of the flagship series are also currently available to stream on Crunchyroll, so newcomers curious about Narumi’s background have an easy way to catch up before diving into the spinoff.

Social chatter has already picked up on the schedule, with fan accounts confirming the weekly Saturday cadence, which makes it simple for viewers to fold the short into their regular anime watching routine throughout the month. That dual platform approach, YouTube for Japan and Crunchyroll internationally, has become something of a signature move for how this franchise handles its side stories and specials.

What to Expect From the ‘Narumi’s Week at Work’ Story

Instead of battlefield action, the short follows Gen Narumi through his responsibilities as captain of the Defense Force’s First Division, and despite his reputation as Japan’s strongest anti kaiju combatant, he routinely skips meetings, avoids paperwork, and spends his free time playing online games. Narumi was introduced as an exceptionally powerful but deeply unserious captain whose skill on the battlefield is rivaled only by his love of video games and his general disinterest in the more mundane parts of his job.

The official synopsis teases that his carefree routine gets interrupted by unexpected challenges, giving audiences a look at his considerably less peaceful worklife. The story draft for the spinoff comes from Kizuku Watanabe, the creator behind the ‘Kaiju No. 8 RELAX’ comedic manga, which explains the lighter, workplace comedy tone running through the shorts.

Kōki Uchiyama reprises his role as Gen Narumi, with the short continuing the core production team behind the TV anime, and Studio Production I.G is animating the project again, with Studio Khara back in charge of creature designs, Yutaka Izubuchi directing, and Mahiro Maeda serving as character designer. That continuity gives fans confidence the tone and visual polish will match what they already love about the mainline show.

‘Kaiju No. 8’ Franchise Momentum Heading Into the Finale

Narumi’s Week at Work arrives ahead of the mainline anime’s upcoming third season, which was confirmed as the show’s Final Chapter at Jump Festa 2026 in December, with the short announced at that same event as the franchise’s next release while the final season remains in production without a firm window. By focusing on one of its most popular supporting characters, the short keeps momentum and visibility for the franchise between its larger story arcs.

The timing lines up with some big numbers for the property too, since as of September 4, ‘Kaiju No. 8’ reached 20 million copies in circulation, including spinoffs like the ‘Kaiju No. 8, Relax’ manga. The manga by Naoya Matsumoto ran on Shueisha’s Shonen Jump Plus platform, and both seasons of the anime adaptation remain available for fans wanting to revisit Kafka Hibino and Mina’s story before the finale.

With Narumi’s chaotic office life proving just as entertaining as his time on the battlefield, it is easy to see why this side story has fans buzzing between major arcs. Now that episode three is nearly here, which part of Narumi’s disastrous work week are you most excited to see play out on screen.
