Vampires' Melody 2

After sleeping for three centuries, the vampire girl Yella, known as the Queen of Darkness, along with her faithful thrall, the young chef and recently turned vampire Raylan, have woken up to find themselves in a modern world, only to be arrested by the humans for failing a routine ID check. Fortunately, the authorities are not able to ascertain the vampire duo's background and true nature, so they have banished Raylan and Yella to a deserted island, leaving them to their fates. How would two hungry vampires from three centuries ago with little knowledge of the ways of the world make a fresh start on an island far away from any continent with no unlucky sap to feed on?
