Episode I-V Fool`s Mate
Upon being pressed about the murders, Maria tells them that Beatrice is the culprit, though Battler refuses to accept this explanation. As they argue, Natsuhi bars everyone inside the room and demands Beatrice show herself. By the time everyone breaks out of the room, they see Natsuhi as she drops dead, apparently having committed suicide. Golden butterflies soon fill the room, and the remaining survivors are killed. Afterward, everyone is brought to Purgatory, revived and joking about how they should have solved the epitaph rather than determine who was committing the murders. However, everyone except Battler is convinced that the culprit is a witch. When Battler insists that everything that happened could have been carried out by human means, he is confronted by Beatrice herself, who challenges Battler to prove that the murders were not caused by magic. Later, Beatrice discusses the events she has set into motion with a rival witch, Bernkastel, who plans to lend her own powers to assist Battler.
