Kokichi Ouma is the Ultimate Supreme Leader, and one of the sixteen students trapped in the killing game of Danganronpa V3: Killing Harmony. Kokichi is a mischievous prankster that serves as the games main antagonist for most of the game. He is an avid liar, and will often lie just to spice things up. He hates being bored, so he often stirs up trouble just for the fun of it. He claims to be the supreme leader of a secret organization, but that's probably a lie too. When he needs to be, he can be very sinister, however. 

Kokichi should have medium-high to high voice, sounding a little bit nasally, however that certainly isn't a requirement. He always has a slight undertone of playfulness in his voice, even when he's saying things that seem to be malicious. His English voice actor is Derek Stephen Prince.
