BEASTARS and the Role of Voss

Shimozuma’s most prominent recurring anime role came through BEASTARS, the Netflix-streamed series adapted from Paru Itagaki’s manga. He voiced Voss across both the first and second seasons, a background predator character whose presence added texture to the show’s morally layered world of carnivores and herbivores. In the third and final season, he returned in a different capacity as a black market doctor, a small but tonally fitting shift given the series’ darker final arc.

Video Game and Broader Voice Work

Outside anime, Shimozuma has taken on Japanese dubs for major international game titles. He voiced Riley Brody in Far Cry 3, Bessamzan in Final Fantasy Crystal Chronicles: Remastered Edition, and Suego Marde in Metal Max 4: The Moonlight Diva. His video game credits also include additional voices in Days Gone, Like a Dragon: Infinite Wealth, and Ace Combat 7: Skies Unknown.

Assassination Classroom and Recurring Anime Presence

Shimozuma played Taisei Yoshida across both television seasons of Assassination Classroom and reprised the role in the theatrical film Gekijōban Ansatsu Kyōshitsu Minna no Jikan. Beyond that franchise, his range of supporting and minor roles spans historical action in Kingdom, cycling drama in Yowamushi Pedal Grande Road, and the fantasy anthology Sorcerous Stabber Orphen, where he recurred as Salua across three seasons.
