A mine-style cafe located in the downtown area of Tokyo.Behind the scenes of pink-haired girls with menhera make-up smiling blankly and asking, ``Welcome back?'', the regulars ``we'' and the store manager plan a secret deal.At the after-hours ``launch,'' he tempts the girls with drinks mixed with foreign-made supplements that get him high.``If you set it up a little bit, you'll get erotic in no time.''At first, there was a light atmosphere, but soon the atmosphere turned into a sigh, someone's clothes coming off, bodies intersecting, and a melting gaze.By the time they realize it, they're all in a group sex party dominated by pleasure.
