I really liked the concept. It could have done with being a bit longer to really explain the setting and get grounded in it. 

The society outside the library wasn't really explored. Characters mention royalty and commoners but nothing more than that, not enough to get a real idea of social hierarchy and how it affects the characters. 

It's a good start to an interesting manga. Looking forward to seeing where it goes.
