The books I gathered earlier, are they?

So you can figure out that much just from seeing the subject of those books.

Although grimoires are mixed in... Perhaps you can read them?

Hmm, I wonder.

Don't tell me this child...

...has a list of every book, their contents, and location...

...all in her head?

Even though the vampire's control on her has long been cut off...

If she continued to handle all of this alone by her own choosing...

...then she's gone far beyond merely "liking" books and has gone mad over them.

A "book-crazed" devil, is it?
