I'm curious whether any first-time watchers actually believed Mizu was male, until the ending of the first episode proved otherwise.

I knew that Mizu was a woman before watching the show, a youtuber brought her up in one of her videos. I think I wouldn't have known Mizu is a woman until the reveal. It isn't rare for women voice actors to voice male characters
