Deep in the heart of 19th Century London, a young nobleman named Cain walks the shadowy cobblestone streets of the aristocratic society in which he was born. Forced to become an Earl upon the untimely death of his father, Cain assumes the role of head of the Hargreaves, a noble family with a dark past. With Riff, his faithful manservant, and Mary Weather, his 10-year-old half sister, Cain investigates the mysterious crimes that seem to follow him wherever he goes.

Story 01: Kaine - Shinogu awakens from a coma in a hospital only to find out that his black hair is now long and red. He looks exactly like his famous rock group vocalist twin brother - Kaine.

In order to let Endorphines continue, their manager has forced Shinogu to take over his brother's place, hoping no one will know the difference. But will they? Kaine's best friend, Die, starts to suspect the fake-Kaine. Meanwhile, one by one, the fans of Endorphines begin to commit sucide after listening to the groups latest CD. Die and 'Kaine' are determined to know the truth and decide to investigate.
