Everyone finds Jessica's body in her locked room, while Kanon's is nowhere to be found, having been erased by Beatrice. After the notion of Kanon killing Jessica is deterred since he gave Jessica his master key, the other servants are marked as the most likely suspects. Battler, meanwhile, finds himself unable to think of any way the crime could have been carried out while knowing the servants are innocent. Rosa sends the servants off, hoping to use them as bait to draw out the culprit. In the process, the servants stumble across Kanon, severely wounded but apparently still alive, who tells them that Rosa was the one who attacked him. However, it is soon discovered that this Kanon is a duplicate created by Beatrice. The fake Kanon attacks the servants, killing Nanjo and Kumasawa before being destroyed by the other servants.

Shannon attempts to defend herself and George, but are killed by Beatrice. The remaining survivors find Nanjo's and Kumasawa's bodies, followed by the bodies of George, Shannon, and Gohda. Rosa begins to suspect Battler after they find another letter, but Battler and Maria blame Beatrice. Rosa and Maria go to take one of the gold bars from the chapel, leaving Genji to bring Battler before Beatrice herself. In exchange for an explanation of how Beatrice used her magic to commit the crimes, Battler is enslaved and humiliated by the witch before being killed by her goat butlers along with Kinzo. Rosa and Maria are also ambushed by the goat butlers and killed as they try to escape. In Purgatory, Beatrice tortures Rosa into accepting her as a witch until Battler stops her, having regained his will to fight her. Beatrice reveals to Bernkastel that she is aware of her meddling before the witches are joined by another, Lambdadelta, who seeks to participate in the next game against Bernkastel.
