Washed-up Tokyo detective Mikogami Keiji is investigating a series of murders where the victims have been torn apart and drained of all blood. Could these grisly new killings be related to the decade-old unsolved murder of the woman he loved? As he renews his vow to find the creature that killed her, he has no idea he's being stalked by a silver-haired girl with secrets of her own. Quicker than you can say 'vampire,' Mikogami finds himself embroiled in a frightening conspiracy with actual monsters--but he'll do whatever it takes in his quest for revenge.
