The Mask of Truth was a mask of black porcelain, completely featureless except for the kanji shinjitsu - Truth - that adorned its right cheek. It could be placed over the face with no need of fasteners or straps. Some said The wearer could see the world as it truly was, with no deceptions or illusions, allowing him to instinctively determine when someone was lying. The drawback was that longer it was worn, the more severe and distorted the effects, and eventually went mad, convinced they were surrounded by enemies on all sides.
