|This article is about a/an episode in Kamen Rider OOO.|
Akira and a worn-down Eiji work to stop the Yummy before the worn-out Okamura stands in the ring once more against his rival.
After his injuries from his fight with the blue Ōmu Yummy are tended to by Akira, Eiji is convinced that Ankh did not create the Yummy but someone else who has his Core Medals did. Furthermore, Eiji realizes the monster's method of granting desires: stealing from others and giving to the host. Date and Shintaro head out on their own to find the Yummy as Eiji is forced to stay behind to recuperate. Despite Kamen Rider Birth's attempt to stop it with a Drill Arm/Caterpillar Leg combo, the blue Ōmu Yummy takes Takeda to where a fully healed Okamura waits for him. Despite his injuries, Eiji arrives to help by giving them the location of where Okamura and Takeda are to box. Eiji arrives at the location just as, the blue Ōmu Yummy fights with Ankh, revealing that he is to take Ankh's Core Medals. After transforming, Kamen Rider OOO fights the Yummy with Kamen Rider Birth and Shintaro arriving to aid him. After assuming Shauta Combo with Kamen Rider Birth using the Birth Day function of the Birth CLAWs as a distraction, Kamen Rider OOO destroys the Ōmu Yummy. The Yummy's spell ends as Okamura promises Takeda that he will go through rehab and fight him again. As Ankh only reveals that he needs Eiji for a complete resurrection, in a body more powerful than his original, they are watched by the mysterious arm that created the Yummy.
