OMG, Patchy is Koakuma's wife. She even read Koakuma's entire yuri collection with her. Such a lovely backstory!
Koakuma, Patchy, Maid Fairies... All the characters in this game have cute sprites. While playing, I really enjoyed reading each book's synopsis and guessing which character each story was about. Some synopses even made me wish those books were real so I could read them from cover to cover.
I think it would be nice to be able to check the title of the book given to each fairy as well as each fairy's reaction on the screen where the player's performance can be viewed. I kept forgetting which book I gave to which fairy, so a few times I couldn't confirm what their favorite books were. And the Magical Book only delays gameplay for a moment, so it doesn't feel like a very threatening trap. This may also need improvement.
