Kokichi is a student in the Ultimate Academy for Gifted Juveniles and a participant of the Killing School Semester. His title is Ultimate Supreme Leader. He is a young man with an innocent look. He has a short stature, thin build, and pale skin. He has purple eyes and medium blackish purple hair. He's an elusive, manipulative person who unabashedly tells lies and says whatever he's thinking. He's also strangely straightforward about his supposed evil nature and admitting to being a liar.
