Clair Vaux Bernardus

Was created by Bernkastel to narrate Requiem of the Golden Witch and serves as a vessel for Yasu. She is a reader similar to the role Ushiromiya Ange performed for Featherine Augustus Aurora during Dawn of the Golden Witch. She is a "substitute actor" without a personality that acts as a vessel to personify both Beatrice and the rules of her game, as Beatrice does not exist in the world presented by Bernkastel. Her name signifies that she is the final guide of Beatrice's game
