"In his years as a Hong Kong police officer, Nishi Tatsuyoshi has never seen murder victims like the ones being found in the abandoned Kowloon Walled City. Bodies completely drained of blood are showing up and rumors of vampires are swirling, forcing officer Nishi into uneasy alliances with the Chiropteran-hunting Red Shield organization and with Hagi -- Saya's mysterious Chevalier -- in order to stop further bloodshed." -- From the back cover.
