Intro. There are two devils. Navy is a humanized devil with navy-colored hair; when she lies her tail often gives her away. She likes hamburgers and wears a gold bracelet, a blue wristwatch, and a cross necklace. She's good at cooking. She hides her horns and is worried about Kaya. Topaz was an experimental fusion of a demon and a fox—he's 17 years old. He likes karaage.
