Cast

Voice Actors

The English voice cast behind Detective Grimoire, Sally and the submarine suspects.

Is The Mermaid Mask fully voiced?

Yes. The Mermaid Mask features a fully voiced English cast for all primary characters and suspects. The important distinction: subtitles are available in 12 languages, but the voice audio is English only — non-English players rely on subtitles to follow the dialogue. This matches SFB Games' signature style: theatrical, character-driven performances that use voice to define each personality.

Known cast

The full official credits list was not released at the time of writing, so specific actor names are to be confirmed — we do not invent them. Based on the game's actual performances, the known character voices follow distinct styles (these are observations of in-game delivery, not an official cast list):

| Character | Voice Performance Style | | --- | --- | | Detective Grimoire | Dry, analytical, deadpan wit | | Sally Spears | Spirited, intuitive, lore-focused | | Sinthia Seafoam | Defensive, authoritative, anxious | | Magnus Mortuga | Deep, commanding presence (flashbacks) | | Symmetry | Soft-spoken, aloof illusionist | | J.D. Wirman | Prickly, defensive author | | The Crew | Eclectic, mysterious, defensive |

As SFB Games releases the full credits list, this page will be updated.
