The job of a book store, naturally, is to sell books. In Denki-gai, a gathering place for people who are true to themselves, even erotic literature is valued merchandise! At Umanohone, a store that sells everything from famous works to doujinshi, an "ero book lover" checks through all the erotic books at incredible speed... No, it's actually what they call an "Ero Books G-man"! Love and eros for all! There is no human who doesn't need eros!
I've bought some doujinshi, too. 
They're all interesting.
