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 is also strangely straightforward about his supposed evil nature, openly claiming to be a leader of a large secret society, admitting to being a liar, and saying he has done nothing but bad things.
