The main characters, Marina Nanami, and classmates Satomi Soma and Miki Yoshino were ordinary high school girls who belonged to the swimming club of their classmates who attended St. Martins Jogakuin. Believing in the words "I will pick up Marina when I grow up" in Australia with my first love partner, Wataru, who is 3 years older, while living in the dormitory of the academy with a pendant of Bloom pearls as a proof of promise I dreamed of a reunion. However, the situation changed completely after the day when Valletta was suddenly delivered to Marina from her father who had not heard for 10 years, and a suspicious devil's hand sneaked up on her. Marina and others who passed the audition for the drama "Happy Salvage" while doubting their relationship with Valletta head to Australia, where they are filmed.
