Gyakuten! The sixth book in the Time Bokan series is Ippatsuman. The corporate office of Time Lease, a company that rents practically everything you could imagine, including strong robots, is located in Osteandel City in the 1990s. They take pride in the fact that they have topped the list of billionaires worldwide for the previous ten years in a row. The legendary evil trio work as top executives at Skull Lease, a different lease company in the same city. Their stated goal is to discredit Time Lease's reputation and usurp them as the industry leader. They do, however, have a plan to establish a base for global conquest. Ippatsuman must move quickly to fight for justice as the evil trio attacks a Time Lease transport robot one day.
