Based on Yasutaka Tsutsui's novel, Fugou Keiji. 
 
The story centers around millionaire Daisuke Kambe, the heir to one of the wealthiest families in Japan, who is assigned as a detective to the Modern Crime Prevention Task Force (aka MCPTF), at the Tokyo Metropolitan Police Department. Taking full advantage of his vast family wealth, he spares no expense in solving complex crimes, and has the tendency to evaluate everything including individual human lives in terms of their monetary value. Haru Katou, a detective with a compassionate heart who believes that money isn’t everything, is chosen as Kambe’s partner but is repulsed by his materialistic attitude. Having diametrically opposing personalities, witness how the two join forces to tackle seemingly unsolvable crimes and mysteries!
