Psycho-Pass

Psycho-Pass (サイコパス, Saiko Pasu) is a very powerful Caster Magic that utilizes the idealistic perception of reality and way of life through the user's own trauma experience to other mages by coming into contact with them. This magic naturally causes the victim to go out of their nature and understanding that they don't even know why they're doing this in the first place, but as they feel it was like second nature to them or else their sixth sense. If they don't abide to that ideal given by the user and rather chose to abandon it, the mage's raw magical energy will be sent off-course. Turning into a berserk-like state that feeds on their true humanism nature in which were never true on living up to their very beliefs. Before long, the mage slowly succumbs to their psychotic symptom affecting their long-term memories being destroyed forever. The after-effect for this magic would be not knowing who they once were in their past life from identity or personal status. However, the user can now easily go out of his way to manipulate the victims again and again at his disposal until they're no longer needed by him. They're now simply a shadow of their former-selves left to be used by this magic and its user.
