Kaiju No. 8 Reveals Narumi’s Week at Work Short’s Main Visual, Fall Release Date

The upcoming Kaiju No. 8 short Narumi’s Week at Work has received a main visual, which depicts the titular character in a leisurely situation. It was also announced that it would be released in fall 2026.

Narumi’s Week at Work was announced with the Kaiju No. 8 TV anime’s “Final Chapter” last December. It’s the second Kaiju No. 8 short after the previously released Hoshina’s Day Off. 

Kaiju No. 8 is based on the Shueisha-published manga by Naoya Matsumoto, which debuted in 2020 on Shonen Jump+ and released its 16th and final volume in September 2025. VIZ Media describes the manga as such: 

Kafka hopes to one day keep his pact with his childhood friend Mina to join the Japan Defense Force and fight by her side. But while she’s out neutralizing kaiju as Third Division captain, Kafka is stuck cleaning up the aftermath of her battles. When a sudden rule change makes Kafka eligible for the Defense Force, he decides to try out for the squad once more. There’s just one problem—he’s made the Defense Force’s neutralization list under the code name Kaiju No. 8.

The anime’s first season premiered in April 2024, while the second season premiered in July 2025. 2025 also saw the launch of Kaiju No.8 The Game on App Store, Google Play, and Steam.
