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

Gen Narumi is swapping kaiju confrontations for the more mundane challenges of a busy work week, complete with an overflowing inbox. This short series first appeared in December 2025 during Jump Festa 2026, and unlike the previous ‘Hoshina’s Day Off’ special, it spans a full month with four episodes airing from September 5 to September 26, 2026.

As episode three approaches, fans of the Defense Force’s most reluctant paperwork warrior are eagerly counting down. With two episodes already released, excitement for the next installment of Narumi’s hilariously ordinary work life continues to build.

The spinoff premiered on September 5 at 8PM JST on the TOHO animation YouTube channel, with the remaining episodes set to release on September 12, 19, and 26. This means episode three will air on Saturday, September 19, maintaining the same weekly Saturday night slot established since the series debuted.

For international viewers, the schedule varies slightly due to time zone differences, as the international rollout on Crunchyroll began a day earlier than the Japanese YouTube release.

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

The one-day gap between the Japanese YouTube release and the international Crunchyroll rollout is common for simulcast anime. Fans watching from abroad should expect episode three to be available locally on Friday, September 18, before the Saturday JST premiere. Regardless, the wait is brief, and the format allows each episode to feel like a standalone story rather than a rushed release.

Narumi’s Week at Work is available for free on the TOHO animation YouTube channel in Japan, while Crunchyroll streams it in regions where the platform already hosts the main ‘Kaiju No. 8’ anime. Both seasons of the flagship series are also currently available on Crunchyroll, making it easy for newcomers to catch up on Narumi’s backstory before diving into the spinoff.

Social media buzz has already begun regarding the schedule, with fan accounts confirming the weekly Saturday release pattern, making it easy for viewers to incorporate the short into their regular anime viewing routine throughout the month. This dual-platform strategy, utilizing YouTube for Japan and Crunchyroll for international audiences, has become a hallmark of how this franchise presents its side stories and specials.

Instead of focusing on battlefield action, the short follows Gen Narumi as he navigates his responsibilities as captain of the Defense Force’s First Division. Despite being known as Japan’s strongest anti-kaiju fighter, he often skips meetings, avoids paperwork, and spends his downtime playing online games. Narumi is portrayed as a remarkably powerful yet laid-back captain whose battlefield prowess is matched only by his passion for video games and his general disinterest in the more tedious aspects of his job.

The official synopsis hints that Narumi’s carefree routine will be disrupted by unforeseen challenges, providing viewers with a glimpse into his considerably less tranquil work life. The story draft for the spinoff comes from Kizuku Watanabe, the creator of the ‘Kaiju No. 8 RELAX’ comedic manga, which explains the lighthearted, workplace comedy tone throughout the shorts.

Kōki Uchiyama reprises his role as Gen Narumi, with the short continuing the core production team behind the TV anime. Studio Production I.G is animating the project, with Studio Khara responsible for creature designs, Yutaka Izubuchi directing, and Mahiro Maeda serving as character designer. This continuity assures fans that the tone and visual quality will align with what they love about the main series.

‘Narumi’s Week at Work’ is being released ahead of the main anime’s upcoming third season, which was confirmed as the show’s Final Chapter at Jump Festa 2026 in December. The short was announced at the same event as the franchise’s next release while the final season is still in production without a set release date. By spotlighting one of its most beloved supporting characters, the short maintains momentum and visibility for the franchise between its larger story arcs.

The timing coincides with significant milestones for the property, 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 was published 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 journey before the finale.

With Narumi’s chaotic office life proving just as entertaining as his adventures on the battlefield, it’s clear why this side story has fans buzzing between major arcs. As episode three approaches, which aspect of Narumi’s tumultuous work week are you most eager to see unfold on screen?
