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!
Uh, it looks like I left 
my phone at Sensei's.
Anscheinend habe ich mein Handy
 bei Sensei vergessen.
Creo que dejé mi celular 
en la casa de Sensei.
Creo que me dejé el móvil en casa de Sensei.
Hm, acho que esqueci 
meu telefone na casa da Sensei.
