‘Kaiju No. 8’s’ ‘Narumi’s Week at Work’ Episode 4 Release Date, Time, Trailer and Where to Watch

Gen Narumi’s brief taste of office life is about to reach its finish line. ‘Kaiju No. 8’ fans have circled their calendars for the fourth and final chapter of the spinoff short ‘Narumi’s Week at Work,’ and the countdown is nearly over.

The series has turned the franchise’s most battle hardened captain into an unlikely comedy lead, and the final entry promises to close out his chaotic week in style.

‘Narumi’s Week at Work’ at Work Release Date

The final episode of ‘Narumi’s Week at Work’ arrives on September 26, wrapping up a four episode run that began on September 5 and launched with weekly Saturday releases at 8 p.m. JST on the TOHO animation channel. Each entry has followed the same steady rhythm, giving fans a predictable weekly appointment to check in on the First Division captain.

The short was first announced back in December 2025 at Jump Festa, alongside news of a conclusion arc for the mainline anime. That timing has made ‘Narumi’s Week at Work’ feel like a bridge project, something to keep the fandom engaged while the bigger story takes shape behind the scenes.

The latter three episodes were scheduled to drop on September 12, 19, and 26, giving the finale its official spot on the calendar. For a spinoff built entirely around workweek chaos, ending on a Friday adjacent Saturday feels almost poetic.

Where to Watch ‘Narumi’s Week at Work’ Episode 4?

Japanese viewers can stream the finale for free, since Narumi’s Week at Work debuts on the TOHO animation YouTube channel with no subscription required domestically. That accessibility has helped the short reach casual viewers who might not otherwise seek out a spinoff series.

International audiences have a different but equally simple path. Kaiju No. 8: Narumi’s Week at Work streams on YouTube and Crunchyroll through its weekly release schedule, and Crunchyroll carries the series across North America, Central America, South America, Europe, Africa, Oceania, the Middle East and CIS.

There is a one day gap between the Japanese YouTube debut and the international Crunchyroll rollout, which is common for simulcast anime. Fans outside Japan tracking the finale should check listings a day earlier than the JST premiere time to avoid confusion.

Both seasons of the mainline ‘Kaiju No. 8’ anime remain available to stream on Crunchyroll as well, so newcomers curious about Narumi’s battlefield reputation can catch up before diving into his workplace misadventures.

‘Narumi’s Week at Work’ Preview and Premise

The entire short hinges on a simple joke, the gap between Narumi’s legend and his actual habits. Despite his reputation as Japan’s strongest anti kaiju combatant, Narumi routinely skips meetings, avoids paperwork, and spends his free time playing online games.

The official synopsis teases that his carefree routine is interrupted by unexpected challenges, showcasing his less peaceful worklife. That setup has given each episode room to swing between deadpan office comedy and brief flashes of the combat skill that made him famous in the first place.

Unlike the main series, this short does not pull from Naoya Matsumoto’s manga. It was written by Kizuku Watanabe, creator of the ‘Kaiju No. 8 Relax’ spinoff manga, giving the story an original angle on a character the TV anime never had time to fully explore.

Kōki Uchiyama reprises his role as Gen Narumi, and the short keeps much of the television anime’s behind the scenes team intact. Shigeyuki Miya returns as director, Tetsuya Nishio continues as character designer and chief animation director, and Yuta Bandoh returns as composer, with Production I.G animating.

‘Narumi’s Week at Work’ Production and Franchise Context

This is not the first time the ‘Kaiju No. 8’ franchise has used a short to fill the gap between major arcs. Narumi’s Week at Work continues the production’s strategy of releasing side stories between major installments, following Hoshina’s Day Off, which premiered before Kaiju No. 8 season 2.

That earlier special screened in Japanese theaters as part of a film compilation package starting in late March 2025, before the second season eventually got underway. The pattern suggests the studio sees these shorts as a way to keep the fandom fed during production gaps on the main series.

Hayato Aragaki, who served as 3D director on the second television season and on the earlier Hoshina side story, returns in the same role for this new short, and Yuka Yamajo handles editing. That continuity has reassured longtime viewers that the spinoff was built with real care rather than handed off as filler.

With the mainline anime’s original run having wrapped in September 2025 after 23 episodes, this short has effectively carried the franchise’s momentum through 2026 while a larger conclusion arc takes shape.

Now that Gen Narumi’s chaotic workweek is finally coming to a close, which side of him do you think will win out in the finale, the legendary fighter or the guy who would rather be gaming?
