>>21016792Eh, I imagine it's more that that's the voice she likes using as Finana, and "is that your real voice" questions are both really annoying and kind of hard to answer (because no, it's not the actual person's real voice, but it IS Finana Ryugu the character's voice).
That said yeah, I'd be very surprised if she didn't have a naturally somewhat high voice anyway. She definitely has to put more effort into the Finance voice than the Finana one.
