At the beginning of the Killing School Life in Danganronpa: Trigger Happy Havoc, Leon appears to be a young high school-aged teenager, but due to the memory loss he is two years older than he believed. He has dyed orange spiked hair, a goatee that's tied into a small ponytail, and pale blue eyes. He wears a white dress shirt (in which he has modified significantly) with the collar popped up, a white shirt with a red grunge skull design, black jeans, and white platform shoes with a black sole.
