Characters in conflict and in competition
From Reiner Braun to Kaigaku.
Distinct roles, different worlds
Yoshimasa Hosoya is a Japanese voice actor whose credits include Reiner Braun in Attack on Titan, Asahi Azumane in Haikyu!! and Kaigaku in Demon Slayer: Kimetsu no Yaiba Infinity Castle.
Reiner and Asahi belong to very different kinds of ensemble stories. One is caught in the conflict of Attack on Titan; the other is part of a volleyball team learning to trust its players. Hosoya’s Japanese-language performances move between those settings.
In Infinity Castle, Hosoya voices Kaigaku, a demon who once trained under the same teacher as Zenitsu. Their shared history gives the confrontation a personal dimension. The film list below covers titles available on FLM.RED, not his complete credits.
