Lilith (リリス?) is a skeleton Western Shinma working for Garline. She arrived with Garline and Barrow to obtain Larva and bring him back to the west. As Larva was battling Barrow, Lilith appeared and used her ocarina to weaken Larva making him easy to capture.
When Miyu encountered her, Lilith used her ocarina to weaken Miyu until Shiina revealed that she was "made like Papier-mâché" and Miyu used her fire attack on Lilith, reducing her to a skeleton and Lilith disintegrated.
