Elma usually takes the form of a human woman with short black hair dyed purple at the ends, and a long unicorn-like horn (which she can freely hide). She has blue eyes and wears glasses when working.
Elma wears a light tan scarf with a black leotard. She wears a purple kimono with pink piping and a dark blue sash over the leotard, with the top pulled down. She has bandages around her legs and sandals. She can be seen with a cobalt blue and turqoise tail (which she can freely hide). Sometimes, she carries around a long, brown trident.
In her dragon form, Elma is a blue sea serpent with a brown horn protruding from her forehead.
Elma loves sweets and can easily be bribed with them, to the point where she loses all control of her bodily functions, becoming a limp mouthwatering vegetable at the sight of chocolate.
Elma is a member of the Harmony Faction of dragons, as such she holds a fondness for humans and hates their need to fight amongst themselves. In one case, she assumed the identity of Seikai the Miko in order to maintain peace within a human city. It was as she was pacifying the populace of the city that she first encountered Tohru. The two would form a truce of sorts in order to observe the human world together, however they fell out after Tohru learned the humans under Elma began to venerate her as a goddess and wage war on non-believers. Following Tohru destroying the palace built for Elma, they briefly fought and went there seperate ways.
After the devestating fight against Tohru, Elma chose to retreat back to the Order dragon's base and stay away from humans for some time.
