In 2017, his secondary role as Wilibald Koenig in the military/magic anime Youjo Senki was his first big opportunity to showcase his acting with some spotlight on it. Koening is part of the military unit under the main character, Tanya Degurechaff.

He’s a quiet, loyal man that doesn’t question her orders.

Still in the same year, he made a brief cameo in The iDOLM@STER SideM, reprising his role as Amehiko Kuzunoha.

Due to the fact that the first season of SideM wasn’t focused on all units that fans know as part 315 Production, fans didn’t get to hear much of Kasama’s acting as Kuzunoha.

Other anime he’s voiced minor roles in include: Spacy Dandy (2014), Arslan Senki (2015), Gate: Jieitai Kanochi nite, Kaku Tatakaeri (2015), Comet Lucifer (2015), Starmyu (2015), VALKYRIE DRIVE -MERMAID- (2015), Binan Koukou Chikyuu Boueibu LOVE!
