Time Bokan Series: Gyakuten Ippatsuman

In Osteandel City, Time Lease has built a fortune by delivering almost anything to almost any era through its Time Courier service. Rival company Skull Lease wants that success for itself and sends the Clean Aku Trio to sabotage deliveries as part of a much larger scheme for power.

Whenever a Time Lease mission is pushed to the brink of failure, the mysterious hero Ippatsuman appears to reverse the situation. Behind the mask is Sokkyu Go, a gifted employee whose psychic powers and giant robots let him fight back against Skull Lease’s increasingly elaborate attacks. Corporate rivalry, time travel, and super-robot battles turn every delivery into a chance for an impossible last-minute comeback.
