Episode IV-II Zugzwang
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.

Umineko: When They Cry
Considered as the third installment in the highly popular "When They Cry" series by 07th Expansion, Umineko no Naku Koro ni takes place on the island of Rokkenjima (六軒島), owned by the immensely wealthy Ushiromiya family. As customary per year, the entire family is gathering on the island for a conference that discusses the current financial situations of each respective person. Because of the family head's poor health, this year involves the topic of the head of the family’s inheritance and how it will be distributed.
However, the family is unaware that the distribution of his wealth is the least of Ushiromiya Kinzo's (family head) concerns for this year's family conference. After being told that his end was approaching by his longtime friend and physician, Kinzo is desperate to meet his life's true love one last time: the Golden Witch, Beatrice. Having immersed himself in black magic for many of the later years in his life, Kinzo instigates a ceremony to revive his beloved upon his family's arrival on Rokkenjima. Soon after, a violent typhoon traps the family on the island and a string of mysterious murders commence, forcing the eighteen people on the island to fight for their lives in a deadly struggle between fantasy and reality.
