The Vampire Bund, a peaceful island nation of vampires off the coast of Tokyo, ruled by Princess Mina Tepes, has seen its share of conflict and turmoil. And yet there are times of relative tranquility when the Bund is a popular tourist destination during daylight hours.

When two teenage tourists, Garcia Fujisaki and his reckless best friend Masaki, ditch their group to find a vampire who will turn Masaki, it's Garcia who pays the price. Awakening as an unwilling creature of the night, Garcia finds himself entangled with a seedy band of terrorists looking to destroy the only known cure for vampirism. Garcia must find the cure and administer it within forty-eight hours, or his condition is irreversible!
