Episode III-II Gambit
Rosa recounts how she met the human Beatrice confined in a hidden mansion, Kuwadorian, on the island twenty years ago and helped her escape, only to see her accidentally fall off a cliff to her death. Beatrice confirms to Battler that she truly died as a human, and that there are currently no more than 18 people on the island, forcing Battler to accept his loved ones as possible culprits. Genji, Shannon, and Kanon are later summoned to Kinzo's study, where they see Beatrice offer him as a sacrifice and kill him. Kanon is pit against the seven Sisters of Purgatory, defeating Lucifer in a duel, though he and Shannon are overwhelmed as they try to fend them all off at once, prompting Genji to euthanize Shannon and Kanon before he is put to rest by Ronove. The Sisters search the mansion for more sacrifices, killing Gohda in the process. They find Kumasawa as well, who claims to have been waiting for Beatrice. Beatrice reveals Kumasawa to be her predecessor and teacher, the former Beatrice.

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.
