Under the shadow of the cyber city "New Eden", the ancient war between vampires and werewolves has evolved into an undercurrent competition for resources. With the abnormal fusion of magic and technology, artificial plasma "blood crystals" have become a scarce commodity to maintain the power of the blood nobles, while the werewolf tribe clings to its last natural faith on the edge of the steel forest. The appearance of a mysterious supplier disrupted the balance of the underground world - the "blood packs" he provided were of astonishing purity and their origin was a mystery, quickly setting off a storm in the black market. What is involved behind this is not only the survival of the two major races, but also the possibility of uncovering the bloody truth about New Eden, the future city, buried deep under the torrent of data and magic circles.
