Dana O'Shee

 is the true mastermind behind the events of Humanoid Monster Bem (2006).

He plans to rule over humans through the use of other yokai, but keeps failing due to the Humanoid Monsters thwarting the other yokais' actions. Thus he masquerades as the yokai exterminator, Genrozai Tanashi (田無 幻狼斎, Tanashi Genrouzai) where he allies with the police to exterminate Bem, Bela and Belo.
