Feng, Dong

A Chinese exorcist who employs potent transformational symbol magic and serves the continental Mafia, Xu Fu. He appears to have been assigned to monitor Shito, whom he views as a "perfect monster" yet "disgustingly beautiful." At times, he inflicts physical and mental abuse on Shito through his symbol magic. He possesses reliable sources and consistently stays a step ahead of Z-Loan. The role of overseeing Shito and working for Xu Fu has been inherited through generations. He is noted to have a wife.
His true name is "Dong Feng," whereas "Touhou" is a title passed down through generations to powerful exorcists, as Shito explains in the ninth volume of the manga.
