A sarcophagus in the warehouse of the art gallery was opened by accident, and Greeed, who had been sealed for 800 years, was resurrected. The resurrected Greeed's power is not complete, so they created "Yummy" with the coins that make up their bodies. Yummy grows by absorbing human desires, and the coins in his body will also increase. Greeed collects coins in this way. Hino Eiji, a young man with no ideals and no desires who was accidentally involved in the resurrection incident, fights Yummy because of his sense of justice. And Ankh, one of the five Greeed, cannot transform except for his right hand because of the lack of coins. Ankh took a fancy to Eiji's simple character, so he gave OOODriver to Eiji, let Eiji transform into Kamen Rider OOO to eliminate Yummy, and get coins from it. What will happen to the battle of Kamen Rider OOO? Can Ankh regain his body? At the same time, what is the purpose of the "Hongshang Foundation" that has a great relationship with Greeed? With many mysteries, the story of Kamen Rider OOO begins...
