Tadeura is the leader of the Oukarengou, also known as the 'half-gray'. The Oukarengou are a group of 'outlaws' in Bunokura, though other characters would describe them as a 'young gang'.
Said to have the self-confidence to turn over a person with just one light motor vehicle, Taedura frequently acts a cover for Douma Kiyoijima when he does something wrong. At the same time though, Douma's father has also extended his influence to get Taedura out of trouble as well.
Tadeura is described as a skinhead man who is more than 6'7" tall with strength deviating from that of a normal person.
