Plot
The story takes place on the man-made floating island of Aqua Eden, where gambling and prostitution are considered legal by the government.

One summer day, Yūuto Mutsura and Naota Kurahashi travel to the island to lose their virginity. During their visit, they meet a girl named Miu, who directs them to a brothel. During a misunderstanding, Miu gets kidnapped, is taken to a harbor and is held for ransom. Yuuto then goes to the harbor to rescue her, where he too is taken hostage. The kidnappers are arrested by an island security task force. During a subsequent misunderstanding, Yuuto is turned into a vampire, learns that Aqua Eden is really a safe haven for vampires and that Miu is a vampire herself.
