ミルキー・オンディーヌ

A slime girl possessing the element of water. Normally she’s as elegant and beautiful as a nymph, but she’s an extreme coward, and her negative thinking often causes trouble for the other elementals. Despite her best intentions, she’s pretty empty-headed. When she was on a walk with her fellow slime people, she became separated, got caught up in all kinds of trouble, and ended up stuck in a drain when Erogelsus found and rescued her. She didn’t have anywhere else to go, so she decided to care of him. [From MangaGamer]
