Among the private buildings the S.A have, one of them is the library. The S.A get their own private library, complete with computers, desks, and lots of books. The regular classes still have their own library, but the S.A get a private one all to themselves.
Like the other S.A buildings, this one is seprated from all the regular classes too, but it's still on the Hakusenkan campuss. In the picture to the left, Hikari is always studying inside the library, although she fell asleep while studying.
