Everybody tries to determine how Eva and Hideyoshi could have been killed when an odd smell begins to fill the mansion. Kanon goes to investigate the boiler room along with Kumasawa, but is mortally wounded in the process. The rest of the family and staff arrive and discover the dying Kanon, as well as Kinzo's partially incinerated body. They decide to retreat to Kinzo's study, which should be the safest room in the house. After they enter, however, a letter from Beatrice mysteriously appears. Since Genji, Nanjo, Kumasawa, or Maria are the only possible suspects for planting the letter, Natsuhi forces them to leave the study. Later that night, the phone rings with Maria singing on the other end. Natsuhi, Battler, George, and Jessica rush downstairs to find Genji, Nanjo, and Kumasawa murdered and Maria standing in the corner, still singing.

Ange briefly withdraws from Beatrice's game to confront Maria over her denial of being neglected by Rosa, but Maria tells her that she is content with Sakutaro ensuring her mother's love. Beatrice decides to show Ange how she, upon noticing how Maria created a soul for Sakutaro, gave a human body to Sakutaro and named Maria the Witch of Origins, joining forces with her in a witch's alliance called Mariage Sorcière. Ange recounts how she too was once a member of this alliance and learned how to summon the seven Sisters of Purgatory, becoming close friends with Mammon in the process. By the year 1998, however, she loses the ability to use magic, and continues her investigation of the Rokkenjima murders. Before she returns to the game, Ange is confronted by Lambdadelta, who tells her that if Battler defeats Beatrice, he will return to her past self in 1986 while her current self will remain alone, and proposes that Ange can remain with her brother if he continues to fight against Beatrice for eternity.

In 1998, Ange arrives at Rokkenjima and continues on alone with Mammon and Sakutaro, only to be ambushed by Kasumi and her men, who proceed to beat and taunt her mercilessly, and destroy Maria's diary. Noticing that Kasumi is being manipulated by the spirit of Eva-Beatrice, Ange miraculously summons the Sisters of Purgatory despite the large amount of magical resistance present, killing Kasumi and her men. Before vanishing, Eva-Beatrice resurrects the long-dead, human Eva to shoot and kill Ange, though Mammon destroys her gun, allowing Ange to kill Eva and make peace with her own emotions towards her. Ange meets with Bernkastel, who confirms that she is nothing more than a piece in the game between Battler and Beatrice. However, Ange remains determined to save her family.
