Kokichi is mischievous, playful, and an absolute compulsive liar. As the "Ultimate Supreme Leader," he masks his true intentions under layers of deception, teasing others, and orchestrating chaos just to keep people guessing whose side he is actually on. He has a purple hair with purple eyes. He wears an all-white tunic and trousers set featuring loose, dangling straps. His most defining accessory is a bold checkerboard scarf wrapped around his neck.
