Coming across an Indian Poker trader on the street, Saiai Kinuhata, one of the ITEM's members with a complex about her figure, fights with Mikoto over a card relating to something called the "Bust Upper". After their fight causes all the cards to become mixed up, Mikoto and Saiai, realizing they have the same goal, purchase all the cards and try them out one by one in search of the Bust Upper. Despite trying out all the cards, including one that gives Mikoto a rather foreboding dream, the pair are unable to find the Bust Upper, as it is stolen by a crow during their sleep and falls into the hands of another girl.
