Kirari Books Meisouchuu!

Kirari Kiryuuin, a rich young lady who doesn't know anything of the world, is introduced by her mother to the historic Meisou Bookstore, which will be the setting of her first part-time job. It turns out the Meisou Bookstore is in fact filled with anime goods, doujinshis, and idol merch—a true otaku bookstore!
