On November 30, Ichika tweeted a sketch of a woman with a hairstyle to Hatsune Miku and has clothes similar to Irina. I wonder if that's supposed to be Maria Moonlit.

Also as far as the protagonist goes, assuming there will only be 1 book, I think there won't be a central protagonist and the role will change from chapter to chapter.
