The appearance of Gretel has strengthened Battler's resolve to face off against Beatrice once again. Both players have become more skillful tacticians over the course of time, and Battler's new "blue truth" ability, along with Gretel's support, will be a boon to his strategy.
As the curtain rises on the fourth game, the Ushiromiya family has gathered on Rokkenjima for their annual meeting. Gretel observes the family she hardly knew with complicated emotions... She must come to terms with the past if she wants to help Battler overcome the Golden Witch!
