211021 UPdate note!

My loyal servants.
I, the Great Demon King Celestina, will be in charge of this update.
In this update, a so-called “Nin……ja?” or something, seems to have been added to the roster of Glass Maidens.

After the Official Art Book was released, many people seemed to like the "Rough Drawings",
So I personally told the slaves of the development team to gather as much artwork as possible,
when adding art of new characters in the Art Book.

As a result, the Art Book includes embarrassing rough drawings of * ehem * Myself, and Eily’s and also Michell's - So, even those who have previously bought the Official Glass Art Books should find things to enjoy in it.
