It wasn't very difficult to locate the library. In fact, there were many students heading towards it too. Zero didn't know that it was such a popular spot and was slightly concerned about being able to find his target with so many demons around.
The library was a very grand looking building, only second to the atrium. In fact, it was located conveniently behind the atrium and beside the garden. Zero wondered why the gardener thought it was a good idea to design high thorny hedges in a way that led people deeper into it only to be met with no place to go. Zero did find the idea of putting small fountains, trees and benches in those places to nowhere really cool. He just didn't think it would be very convenient to walk out of such a place with some of those hedges constantly shifting positions. The thorny bushes were alive after all, ready to snag some unsuspecting people's ankles for a tasty sip of blood.
