Holiday dragons are a very mysterious breed. They are only seen during winter, and even then it is hard to catch a glimpse of one. They are responsible for the general cheer that spreads during the holidays. In essence, they are the “Spirits of Winter.”

Dragons are highly-intelligent reptilian creatures that—from a human perspective, at least—appear to live forever. Many different varieties of dragon exist, each with their own unique qualities, habitats, and behavior. Adolescence in dragons is usually marked by the growth of a hatchling’s wings, although not all breeds of dragons grow wings and some breeds have other traits that indicate the beginning of maturation. In Galsreim, dragons and humans coexist peacefully.

Her name means "Love" in Japanese. She is one of the many daughters of Kentaro and Kiyomi; and was raised alongside her sisters Seiya and Hikari. She is a wonderful dragon with a sparkling personality. She is very kind and playful, and enjoys hanging out with other dragons. She is an excellent singer and dancer, and loves to twirl her ribbons around just to hear them tinkle. She is the first dragon in the Ryuu Tanima Colony to have more than one mate. Zenryoku and she were courting, and already madly in love, when Aijou met Kin-Noeru and fell in love with him as well. Many of the other dragons figured that she'd have to choose one of them; instead, after talking with the two males, she chose both. Neither of her mates minds their arrangement, and together they are a happy family. Aijou loves both of her mates with all her heart and more, and they love her just as much.
