Synopsis
The story follows a normal high school boy, Kakeru Daichi, and the melon juice soda can he gets from a vending machine. That can suddenly morphs into a beautiful but standoffish girl, whom Kakeru dubs "Melon," and then additional "Akikan" (empty can) girls start appearing. These Akikan girls, however, must be infused with carbon dioxide in order to transform into human form.
