While Battler Ushiromiya is unable to defeat her and explain how the murders occurred without magic, he refuses to acknowledge Beatrice, forcing their game to continue with higher stakes. As the events on Rokkenjima are begin again, Eva Ushiromiya succeeds in solving the Epitaph of the Golden Witch in order to become the head of the Ushiromiya family and inherit the family's massive fortune. However, a phantom of Eva's dark side emerges and uncontrollably begins to wreck havoc on the island as Beatrice's successor.
