Kamen Rider OOO's airing also coincided with the 40th anniversary of the franchise. The interesting part is that rather than painting a clear Black-and-White picture about the topic, their story advocates a healthy balance between all-consuming obsession and a purposeless void in short, it presents a pragmatic view about desire. The major recurring theme in Kamen Rider OOO is about 'desire' note Yokubō or 'greed'.

There's also the Kougami Foundation, an Omniscient Council of Vagueness who pledge their resources to help Eiji in his fight against the Greeed. Eiji just wants to use the power to protect others, but Ankh plans to use the naive boy as his Unwitting Pawn to destroy the other Greeeds, rebuild his body from their Medals, and seize the power of the Multi King for himself. Having plundered several Core Medals from the other Greeed but without a body to use them, Ankh manipulates Eiji into accepting a forbidden Transformation Trinket and using his Core Medals to transform into Kamen Rider OOO. He runs into Ankh, a bird-type Greeed whose body has been reduced to a single arm.

Enter Eiji Hino: an Unlucky Everydude and vagrant without any kind of drive, ambition or passion.
