New Kaiju No. 8 Anime Short Unveils Story, Staff, Fall Debut
The staff for the new anime short of Naoya Matsumoto's Kaiju No. 8 manga presented its main visual on Saturday and announced its story, staff, returning lead cast member, and premiere this fall. Kizuku Watanabe, the creator of the Kaiju No. 8: Relax spinoff manga, conceived the story of the "Narumi's Week at Work" ("Narumi no Heijitsu") short.
Gen Narumi, the captain of the Defense Force's First Division, is known as "Japan's Strongest Anti-Kaiju Combatant." Thanks to his overwhelming prowess (and resulting overwhelming jerky behavior), he goes AWOL on meetings, adroitly shirks office work, and plays online games in his R&R time — however, even he sometimes deals with unexpected counterattacks …? This is the story of the strongest man during his less-than-peaceful week at work.
The staff from the television anime is returning for this short, including director Shigeyuki Miya, character designer and chief animation director Tetsuya Nishio, musical composer Yūta Bandō, and the animation studio Production I.G. The other staff members include:
- Kaiju Designs: Mahiro Maeda
- Art Director: Shinji Kimura
- Color Key Artist: Izumi Hirose
- Compositing Director of Photography: Eiji Arai
- Sound Director: Fumiyuki Go
- Kaiju Designs & Design Works: Khara
