Story:
Kamiya Kouji was once a volunteer of the Kogami Foundation looking for a job. But when he was chosen to take up the new NeOOO project; a combination of OOO's cores and Birth's cells, he accepted and learned of the original OOO and Eiji Hino, the new OOO of the 20th/21th century.

But when he learned that Eiji had been turned back into a Greeed and became evil, Kouji becomes NeOOO to stop him and find the answers.

Like some princes, he doesn't know how to do anything when his rich parents sent him to the Cous Coussier to learn how to live an ordinary life. And makes friends with Hina, Gotou & Date. Even the Reptile Greeed named Ibaru.
