After a devastating earthquake that left most of Japan in ruins, the district ward of Shinjuku in Tokyo has opened up a doorway into another dimension-becoming the halfway-house suspended between the mortal world and the supernatural. Coming from the deepest and darkest parts of China, four immortal vampires, led by one of unmatched beauty and who goes by the ubiquitous title "Princess," mystically sail into landlocked Shinjuku aboard an ancient ghost ship one roiling hot night. She and her ancient undead entourage with powers never before seen of vampires, have surmounted four thousand years of space and time to seize control of  Shinjuku and make it their own. Can two humans, Setsura and Mephisto, stop them before they plunge the living populace into a new level of fear and slavery none can escape?
