Fans of Kaiju No. 8 are getting a bonus treat this autumn. A brand-new spin-off anime following everyone’s reluctant Section 3 captain, Gen Narumi, has been officially confirmed — and it’s coming soon. 鳴海の平日 / Narumi’s Week at Work premieres on 5 September 2026, and the first PV just dropped.
From the looks of it, this spin-off leans hard into the comedy side of Narumi’s character — think bureaucratic headaches, questionable delegation, and the kind of low-key disasters that only happen when you’re the strongest fighter in the Defence Force but absolutely hopeless at desk work.
The announcement PV dropped on 5 August from TOHO Animation’s official YouTube channel, giving us our first proper look at the spin-off’s tone and style. It captures Narumi’s chaotic energy perfectly while cranking the office comedy up to eleven.
Don’t let the comedic premise fool you. Narumi is still every bit the powerhouse we know from the main series — the action visual confirms his signature pink/purple lightning aesthetic is fully intact. Even a spin-off about Monday morning meetings isn’t walking away from the action entirely.
And then there’s this — Narumi surrounded by YAMAZON delivery boxes, clearly getting nothing done. This is the exact energy the show is going for, and we are absolutely here for it.
Where to Watch in Singapore
鳴海の平日 / Narumi’s Week at Work will be streaming from 5 September 2026 on TOHO Animation’s official YouTube channel — which means it’s free and accessible globally, Singapore and Southeast Asia very much included. No subscription needed.
Crunchyroll will carry the series for viewers in North America, Central and South America, Europe, Africa, Oceania, the Middle East, and CIS regions. For everyone else in the region, TOHO Animation’s YouTube channel is the place to be on 5 September.
With the main Kaiju No. 8 series still in full swing, this spin-off is the perfect way to get a little more Narumi content between the big battles. 5 September — mark it.
