Laila tries to remember the secret passage to the room with the Moonstone. After remembering Zofis' song, she remembers that the door is behind the rightmost statue. Megumi's team meanwhile end up in a room with three statue heads. The heads demand the answer to a question in order to pass. The question is, "Who is the most beautiful?" The four of them want to say themselves but are unable to. Li-en ends up using a spell and destroying the statues. Megumi's team arrives to the moonstone room and are attacked by the Mamodo there. Megumi runs out of energy and loses consciousness during the battle. Wonrei attempts to protect her and is stabbed through the stomach by the Mamodo. Kiyo's team arrives and sees the giant Mamodo.
