The Ultimate Vampire Resource and Directory

Lyrica is amused by their notion that she is a vampire. She claims that the flowers she was seen eating were merely flower-shaped sweets. Relieved, Momoko asks to use the bathroom, and Lyrica offers to show her the way. After a while, Chibiusa worries that Momoko has been gone a long time, and she and Kyuusuke go to investigate. Chibiusa eventually finds Lyrica in a huge chamber, standing over an unconscious Momoko. When she and Kyuusuke enter the room, they also find Ishihara and Kuwano, likewise unconscious. Lyrica is suddenly nowhere to be found, until she appears behind them, calmly commenting that they have discovered her secret: she has been drinking blood from the incapacitated children. Lyrica transforms into a vampire-like Lemures and knocks Kyuusuke out cold before preparing to attack Chibiusa. She is stopped by Tuxedo Mask, while Usagi appears in the doorway. Usagi and Chibiusa transform and confront the vampire. The rest of the Sailor Team arrive, and paralyse the vampire with their new special move: Sailor Special Garlic Attack (merely expelling their barbecue-fueled breath at the vampire). Sailor Chibi Moon calls Pegasus, and Sailor Moon then fires a Moon Gorgeous Meditation at the monster. She defiantly claims that there are many more of her kind lying in wait, then disappears
