Silas is a street magician who lives among the lower classes in London. In an accident during a magic performance, he merged with the mysterious "Devil's Contract" and awakened his negative emotional system. He discovered that under this modern civilized society, there are actually vampires, werewolves and mystics who feed on humans. Silas must rise through the ranks by performing extremely thrilling, suspenseful "magic" that captures the audience's fear, disbelief, and despair. While investigating an "impossible crime" case of corpse dismemberment, he met the cold-blooded forensic doctor Vivian, and the two were forced to be involved in a world-destroying conspiracy aimed at resurrecting an ancient evil god. Silas walked between light and shadow, using deadly magic tricks to stage a gorgeous performance of harvesting darkness in the modern city.
