In 2105, the protracted thousand-year jihad between the Demon Party and the Camarilla entered another thousand years. The Prince of the Demon Party, who was once only willing to believe in his own power, began to consider using others to fight against the Camarilla. Taking advantage of the opportunity of a few crazy scientists to shift their research interest in anti-aging to the mechanism of vampire immortality, they sent their subordinates to hunt down the humans living in the Camarilla settlements in order to provoke conflicts between the Camarilla and humans.
Out of fear of the unknown powerful force, mankind has once again fallen into the frenzy of exterminating those with supernatural powers following the extermination of evil spirits in the 13th to 15th centuries. The Camarilla Senate sent a prince to negotiate with human leaders after a consensus, but something unexpected happened, and a war broke out between humans and the Camarilla. After 15 years, the long bloody battle came to an end with the signing of the Red Sea Agreement by both parties; during the same period, the secret party also gained a certain amount of public territory, and the Vampires, who had long lived in the shadow of human society, finally officially entered the stage of history. Unwilling to give up, the Demon Party secretly once again hunted humans in the name of the Secret Party.
In order to maintain the delicate peace and connection between humans and vampires, the Secret Party cooperates with the human national security department and sets up a dedicated department responsible for monitoring the daily behavior of vampires and arresting rebels who violate the agreement. In the spring of 2140, Laschat, the son of the late Earl of Ventrue, was directly appointed by the prince to partner with Inspector Shane, who had been in office for 10 years, to hunt down the rebel Rex who had been on the run for many years. The seemingly simple task does not seem to be that simple, and there are some ulterior purposes hidden behind it...
