Ten thousand years into the future, the world has changed dramatically. Monsters roam the land freely, yet people, armed with advanced weapons and cybernetic horses, live simple lives that feel more like those of centuries past. The story centers on a small hamlet beset by monster attacks and ruled in shadow by Count Magnus Lee, a vampire lord who has dominated the region for millennia. When a young girl is bitten by the Count and chosen as his plaything, she turns to a quiet wandering stranger named D for help. D, one of the world’s finest vampire hunters, sets out to cut through Magnus Lee’s many minions and bring an end to the Count’s reign.
