Kaiju No. 8 spin-off about Gen Narumi gets first trailer and premiere date

The four-episode mini-series will show the daily life of the First Division captain.

The creators of the anime "Kaiju No. 8" have unveiled the first trailer for the spin-off Kaiju No. 8: Narumi’s Week at Work and announced its premiere date. The first episode will be released on September 5, 2026, with new episodes published every Saturday on the TOHO animation YouTube channel and other platforms.

The main character of the project will be Gen Narumi — captain of the First Division and one of the strongest fighters in the Japan Self-Defense Force. Unlike the main story, which focuses on battles with kaiju, the spin-off will show the hero in everyday situations.
