Чікуджьоїн Маґане

A villainous character from the light novel series "Yasou Kiroku".

Her ability is "Infinite Deception of Words", which allows her to bend reality through words. By telling a lie and manipulating somebody into rejecting that claim, it creates a "lie of a lie" which by proxy makes the initial claim become real. She can reverse cause and effect by making the person under her spell deny what she asked; reality that was bent will have it effects stuck in the real world.
