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

Gen Narumi’s brief experience in the office is nearing its conclusion. Fans of ‘Kaiju No. 8’ have marked their calendars for the fourth and final chapter of the spinoff short ‘Narumi’s Week at Work,’ and the countdown is almost over.

This series has transformed the franchise’s most battle-hardened captain into an unexpected comedic lead, and the final episode is set to wrap up his chaotic week in a memorable way.

The last episode of ‘Narumi’s Week at Work’ is scheduled to premiere on September 26, concluding a four-episode run that kicked off on September 5, with new episodes released weekly on Saturdays at 8 p.m. JST on the TOHO animation channel. Each episode has followed a consistent release schedule, allowing fans to have a regular appointment to check in on the First Division captain.

This short was first revealed in December 2025 at Jump Festa, coinciding with announcements about a conclusion arc for the mainline anime. This timing has given ‘Narumi’s Week at Work’ the feel of a bridge project, keeping fans engaged while the larger story develops behind the scenes.

The subsequent episodes were set to release on September 12, 19, and 26, marking the finale’s official place on the calendar. For a spinoff focused on workweek chaos, concluding on a Friday before Saturday feels almost poetic.

Japanese viewers can stream the finale for free, as ‘Narumi’s Week at Work’ debuts on the TOHO animation YouTube channel without any subscription needed domestically. This accessibility has allowed the short to reach casual viewers who might not typically seek out a spinoff series.

International viewers have a similarly straightforward option. ‘Kaiju No. 8: Narumi’s Week at Work’ streams on YouTube and Crunchyroll according to its weekly release schedule, with Crunchyroll offering 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 release and the international Crunchyroll launch, which is typical for simulcast anime. Fans outside Japan looking for the finale should check listings a day earlier than the JST premiere time to avoid any confusion.

Both seasons of the mainline ‘Kaiju No. 8’ anime are also available for streaming on Crunchyroll, allowing newcomers interested in Narumi’s battlefield reputation to catch up before diving into his workplace antics.

The entire short is built around a simple premise: the contrast between Narumi’s legendary status and his actual behavior. Despite being Japan’s strongest anti-kaiju fighter, Narumi often skips meetings, avoids paperwork, and spends his leisure time gaming.

The official synopsis hints that his laid-back routine is disrupted by unforeseen challenges, highlighting his less-than-peaceful work life. This setup has allowed each episode to oscillate between deadpan office humor and brief glimpses of the combat skills that made him famous.

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

Kōki Uchiyama reprises his role as Gen Narumi, and the short retains much of the television anime’s behind-the-scenes team. 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 handling the animation.

This is not the first instance of the ‘Kaiju No. 8’ franchise utilizing a short to bridge the gap between major arcs. ‘Narumi’s Week at Work’ continues the trend of releasing side stories between significant installments, following ‘Hoshina’s Day Off,’ which debuted before ‘Kaiju No. 8’ season 2.

The earlier special was screened in Japanese theaters as part of a film compilation package starting in late March 2025, prior to the second season’s launch. This pattern suggests that the studio views these shorts as a means to keep the fandom engaged during production gaps in the main series.

Hayato Aragaki, who served as 3D director on the second television season and the earlier Hoshina side story, returns in the same capacity for this new short, with Yuka Yamajo handling editing. This continuity has reassured long-time viewers that the spinoff was crafted with genuine care rather than being treated as filler.

With the mainline anime’s original run concluding in September 2025 after 23 episodes, this short has effectively maintained the franchise’s momentum through 2026 while a larger conclusion arc is developed.

As Gen Narumi’s chaotic workweek comes to an end, which side of him do you think will prevail in the finale: the legendary fighter or the guy who prefers gaming?
