Story
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 separate ways.

After the devastating fight against Tohru, Elma chose to retreat back to the Order dragon's base and stay away from humans for some time.
