Synopsis
I've been waiting for you, Mr. Itsuki Kuroma. My name is Livre Blanche and I am asking for information about this library. You will use me to seal the "death book" that has escaped from this library. In the process, all of this body is enslaved to Itsuki-sama. I exist for that. So Itsuki-sama, from now on together ─

─Itsuki-sama? Why don't you look here? Is it because I'm a maid outfit? Is it because I don't look like a human? I understand. From now on, I would like to ask you to take off your clothes and check your body to prove it.
