Vampire Bund, a peaceful island nation of vampires at the Tokyo coast, driven by the princess of Mina Trene, saw his share of conflict and confusion. However, there are moments of relative peace when the Bund is a popular tourist destination. When two teen tourists visit the Bund and unexpectedly become vampires, they seek help to Mine and her faithful bodyguard Libancope Akir. Their only hope-find a medicine to reverse your vampirism for forty-eight hours, otherwise they will forever stay in a trap like vampires. Unfortunately for them, their race against time becomes a game in a cat-mouse, which takes them all over the Bunda in search of the only person who has the key to their salvation.
