Professor Ootsuki
Ootsuki is the foremost Japanese member of the Witch Hunt, an international organization of occult enthusiasts dedicated to researching the tragedy on Rokkenjima from a magical perspective. However, their presence and activities are less than welcome by the surviving members of the victims on Rokkenjima, having stirred up the tabloids in a very unpleasant light. The name of this organization was borrowed from the English fan translation group for the game, also called "Witch Hunt."
