Frederica Bernkastel

A mysterious witch who appears to Battler following the first game, providing advice and telling him she will support him in his endeavors to solve the mystery of the witch Beatrice. Although an ally to Battler, Bernkastel has a twisted personality and refers to herself as the "cruelest witch in the world", and is only interested in Beatrice's game as a chance to escape her own boredom. She is known as the Witch of Miracles, and she has the power to reset any situation and realize a goal, eventually securing victory even with a 0.0000000000001% probability, so long as it is not zero. Initially stoic, cold, and calm, she slowly reveals herself to be just as impish and cruel as her rival, Lambdadelta.
