Vampire Hunter D Volume 2: Raiser of Gales

The people of the village of Tepes once cowered in fear beneath the shadow of the Nobility manor. But the Nobility moved on, and the castle sat empty, a place whispered of in ghost stories to caution young people to stay away. One day four of the village children vanished. Only three returned, with no memory of what had happened or where they went. That was ten years ago. Now, in the year 12,090 A.D., vampires who can walk in the daylight have appeared. Did the disappearance of the children have something to do with the undead's newfound powers?
