The story begins with Mutsura Yuuto accompanying his friend
on a holiday to Aqua Eden, an artificial island city where gambling and the sex
industry are legal.
However, his holiday plans are laid to waste after he gets
involved in a kidnapping; to make matters worse, he ends up getting turned into
a vampire.
As a vampire, he can no longer leave Aqua Eden; so with
nowhere else to go, he decides to enrol in a special school for vampires on the
island — and thus, his new night life begins!
