This young man is 18 years old. He is the head of the Duanmu (Tanmoku) Clan, a family with a long and reputable history of raising powerful Yangmingsi (Youmeishi) exorcists. Blessed with the traits of a Yangmingsi (Youmeishi), he became the clan head at just the age of eight. He has great spiritual power, and is always calm and cool. To someone like Duanmu (Tanmoku), who has spent his life in solitude, Yang Jinghua (You Keika) is a very special existence to him, since he's the only one who treats him like anybody else. Ever since Meeting Yang Jinghua (You Keika), Duanmu (Tanmoku) has started gaining back some of his traits as a normal human being.
