♔The world belongs to Kokichi Oma♔

A boy whose Ultimate Talent is being the supreme leader of an evil secret organization that boasts a membership of over 10,000 people. However, there is no proof that such an organization actually exists. Even the Ultimate Detective is unfamiliar with the identity of Kokichi's organization.

As a self-professed liar, Kokichi revels in blurring the lines that separates fact from fiction. He has a tendency to say whatever pops into his head, and is prone to theatrical outbursts of crocodile tears. But don't let his innocent smile fool you- as a supreme leader of evil, Kokichi feels no remorse over tormenting his classmates.
