Norio Tsuburaya is a first-year student of the high school. Norio used to consider himself an average student and was puzzled by the amount of sexual attention he was paid to. Later it was revealed that he is actially a Madara (=a person who doesn't come from monkeys). Being a 'newborn Madara', Norio is not able to hide his true identity efficiently and sometims loses control over himself, letting his true identity come out. Thus Yonekuni Madarame tries to teach Norio how to handle true identities.
Apart from communicating to Madarame brothers, Norio is also a good friend of Teruhiko Kumakashi.
