In the near future in Japan, Annaffiare is a theme park located on a giant floating man-made island where dreams come true. There is also a separate ‘city’ on the island where the employees and those related to the theme park reside and go about their lives. Kazuomi was born on Annaffiare and attends a school specializing in management and administration of entertainment facilities. One day, he undergoes on-site training at the theme park and learns about the feelings of the girls, strengthening the bonds between them.
