Rosa's siblings and their spouses go missing, while the remaining guests find the chapel door locked. Finding the key inside the envelope Beatrice gave Maria, everyone enters and find the missing people murdered inside, along with some of Kinzo's hidden gold. Jessica and Kanon are ambushed by Beatrice, who summons her legion of goat servants against them. Kanon fights off the goats until Beatrice summons two Stakes of Purgatory, Asmodeus and Satan, who kill Jessica and Kanon. In Purgatory, Battler and Beatrice suspend their game to determine how the first six people could have been murdered inside a locked room. Battler begins forming several theories, but Beatrice counters most of them, using red text to speak the truth. However, Battler manages to catch Beatrice off guard by theorizing that the culprit could have taken the key from the envelope, locked the dead bodies in the room, and put the key back where it was. Beatrice congratulates Battler, but remains confident he will submit.

After the bodies of Rosa and Maria are found, Rudolf, Kyrie, and Hideyoshi go to retrieve food from the mansion, only to be trapped inside by Eva-Beatrice. Two Stakes of Purgatory, Leviathan and Belphegor, are sent to kill Rudolf and Kyrie, though they manage to outmaneuver and defeat them. Eva-Beatrice summons more powerful furniture, the Siesta Sisters, who successfully kill Rudolf and Kyrie. Hideyoshi confronts Eva-Beatrice to knock sense into her, but is killed by her as well. Beatrice berates Eva-Beatrice for ignoring her advice, but Eva-Beatrice tells her off, revealing she knows that acting dignified is only a means for Beatrice to get back in Battler's good graces in Purgatory. However, Battler is convinced to continue playing with Beatrice if he is to make any progress, though he still refuses to forgive her. Virgilia, meanwhile, meets with Beatrice and encourages her to act more passively if she is to make Battler accept witches.
