Kokichi describes himself as an evil supreme leader, and often claims that this title is the reason behind many of his questionable actions as if he is expected to fulfill his role. He is an elusive and manipulative person who unabashedly tells lies and says whatever he's thinking. He often says after a sentence that he was just "lying" even if he was telling the truth in some scenarios. He often ends his sentences with "right?" Or some other word asking for confirmation.
