"Alright let's goooo~!" Estelle prompted, skipping up the steps, through the museum, and into the library.

Spreading her arms out, Estelle started, "Well here we are~ Take your pick Shizuo-san~ Feel free to ask me any questions about where you can find specific types of books if you need them~"

Well she did kind of practically live in this place for two months that one time.
