The aquatope on white sand

Kukuru Misakino is a 18-year-old girl who works at an aquarium and she encounters a former idol who lost her place in Tokyo and escaped to Okinawa named Fuuka Miyazawa. Kukuru and Fuuka spend their days at the aquarium, their hearts filled with their own passions. But their precious place is about to be shut down forever. The girls face their dreams and reality, loneliness and friendships, bonds and conflicts... This summer is about to turn a glimmering, new page.
