Quick answer
Beast of Reincarnation includes English voice acting. If the game starts with Japanese audio, return to the title or start menu, open Settings, and change the voice language to English. Players report that this option is not exposed in the in-game pause settings.
Change the voice language
- Leave active gameplay and return to the title or start menu.
- Open Settings from that menu rather than the in-game pause menu.
- Find the voice-language setting and select English.
- Return to the game and confirm that spoken dialogue now uses English audio.
- If the option is missing, capture the title-menu settings screen and confirm that Steam installed the current launch build before reporting it.
What is officially supported
The official Steam language table marks both English and Japanese as languages with full audio support. Other listed languages provide interface and subtitle support but are not marked for full audio on the store page.
Known source limitation
The exact menu label and whether a restart is required were not documented in the sources reviewed. The reliable part of the community guidance is the menu location: make the change from the title or start menu, not while gameplay is paused.
