A water dragon belonging to the Order faction, rival to Tohru's Chaos faction, who ends up working alongside Kobayashi at her office after getting stuck in the human world. She is as powerful as she is diligent and driven, but also naive, indecisive, and easily swayed by food (primarily sweets) due to her low income. Her human form is distinguished by purple hair, a horn (which she hides for work), her habit of having a jacket or kimono hanging off her shoulder, and wielding a trident; Elma Joui (上井 エルマ, Jōi Eruma) is the identity she uses while in Kobayashi's workplace.
