The Medal System (メダルシステム Medaru Shisutemu) is a system created by Doctor Maki of the Kougami Foundation, overseen by chairman Kousei Kougami, invented to efficiently use the desire-fuelled O Medals. Doctor Maki's original Medal System was created to utilize Cell Medals. These included the Candroid robots, the Ridevendor which could function as both a vending machine to store said Candroids as well as a motorcycle, and the Medajalibur sword which was given to Eiji Hino as a gift when he transformed into the modern day Kamen Rider OOO. This Medal System culminated with the creation of a Rider Driver allowing access to a new Rider System, Kamen Rider Birth, utilizing the Birth Buster weapon as well as in-built Birth CLAWs.
