Gen Narumi is back for another round of desk duty in the Kaiju No. 8 spin-off, Narumi’s Week at Work. The short anime series continues its four-episode run this month, with Episode 3 set to arrive for international audiences on Crunchyroll and in Japan on the TOHO animation YouTube channel. The third installment lands on Saturday, September 19, 2026 (JST), bringing viewers closer to the end of Narumi’s chaotic work week.
The spin-off, which first surfaced in December 2025 during Jump Festa 2026, trades the franchise’s massive kaiju battles for a closer look at what the First Division captain actually does when he is not saving Japan. Kōki Uchiyama reprises his role as Gen Narumi, and the story draft comes from Kizuku Watanabe, who previously worked on the comedy spin-off Kaiju No. 8: Relax.
Kaiju No. 8 Narumi’s Week at Work Episode 3 Release Date and Time
The spinoff debuted on September 5 at 8 PM JST on the TOHO animation YouTube channel, with the remaining three episodes scheduled to drop on September 12, 19, and 26. Episode 3 follows the same weekly Saturday night slot the series has kept since its premiere.
International viewers on Crunchyroll began streaming the series on September 4, with new episodes arriving weekly across North America, Central America, South America, Europe, Africa, Oceania, the Middle East, and CIS territories. The one-day gap between the Japanese YouTube debut and the international Crunchyroll rollout means fans tracking the series from outside Japan should expect Episode 3 to land Friday, September 18 locally before the Saturday JST premiere catches up.

The dual platform approach, YouTube for Japan and Crunchyroll internationally, has become a signature move for how this franchise handles its side stories and specials. Both seasons of the flagship Kaiju No. 8 series remain available on Crunchyroll for viewers who want to catch up on Narumi’s larger role in the story.
What Happened in the Previous Episode of Kaiju No. 8 Season 2
The main Kaiju No. 8 anime’s second season aired from July to September 2025, with Episode 2 titled “The Next Generation’s Trial.” The episode followed Kafka Hibino’s struggle to fit in among his new comrades in the Anti-Kaiju Defense Force First Division. Isao Shinomiya’s words weighed heavily on Kafka as he fought for his life with every move under the Defense Force’s watchful eyes.
Gen Narumi once again stole Kafka’s spotlight as the series explored the new character’s rich dichotomy. Narumi might be the most powerful soldier in the Defense Force, but he is also undeniably immature. Yet when the greatest threat ever seen in Kaiju No. 8 suddenly reemerged, Narumi stood ready as Kafka faltered under pressure.
The episode began by continuing the extra credit sequence from the previous episode, introducing what the audience was led to believe was the main threat. The scene shifted to the Anti-Kaiju Defense Force Division 1 headquarters as the soldiers finished their training. Every Defense Force soldier took a moment to catch their breath, but Kafka Hibino was noticeably more winded than his comrades. In contrast, Kikoru Shinomiya seemed to have barely exerted any effort on the same workout, illustrating her strength through the absence of her exhaustion.
Kikoru is a prodigy on top of being genetically gifted. Her father, Isao, is the commander of the whole Defense Force, meaning she has no choice but to be her absolute best. Kafka, on the other hand, is almost incapable without his powers. The episode’s presentation, including its pointed title, made it clear that the anime’s beloved protagonist was about to be pushed to his limits.
Key Moments in Narumi’s Week at Work Episode 3
The short anime focuses on Gen Narumi through his responsibilities as captain of the Defense Force’s First Division. Despite his reputation as Japan’s strongest anti-kaiju combatant, he routinely skips meetings, avoids paperwork, and spends his free time playing online games. His carefree routine gets interrupted by unexpected challenges, giving audiences a look at his considerably less peaceful work life.
Episode 3 marks the halfway point of the project, which is built around a much quieter kind of chaos than kaiju battles. The premise remains a sharp contrast to what longtime viewers expect from the franchise. Rather than focusing on the Defense Force’s enormous monster fights, Narumi’s Week at Work looks closely at what one of the organization’s strongest fighters actually does when he is not saving Japan.
The tone bounces between genuine action beats and quieter, almost slice-of-life stretches, which gives Narumi more texture than most shonen side characters ever get. There is something refreshing about watching a competent adult navigate a world like this, rather than a teenager stumbling through it. The short series fills in a character who is easy to admire from a distance and harder to understand up close.
