Enma Kozato

Enma Kozato is a rather gloomy and introverted transfer student to Namimori Middle School. His social skills are poor at best; his shy demeanor and quiet voice make him an easy target for bullying. He appears to be weak-minded, even to the point that Hana Kurokawa describes him as "the type who'd get teased a lot" and reminding Tsuna of the way he used to be (and, in many aspects, still is). His red eyes have a symbol very similar to the crest on his ring. Later, It's revealed that he is the leader of the Shimon Mafia Family. He is voiced by Uchiyama Kouki in the Katekyo Hitman REBORN! VOMIC.
