Anagallis Dragons are a medium-sized omnivorous breed. Widespread and adaptable, their easygoing nature enables them to flourish under most conditions. They are social creatures, fun-loving and outgoing, and will readily defend smaller dragons from others’ aggression. They are fond of sunshine, and can often be found basking on rocks; on cloudy or stormy days they are more reluctant to venture out, and will often hide themselves away until the weather is more favorable.

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.

Empathic and with a good understanding of how other dragons think, Saikou is often sought out by other dragons in the Sylvain clan when they need to practice talking to someone they are interested in courting. A gifted mimic, Saikou helps his siblings feel less nervous about approaching the dragon they admire by imitating that dragon's voice and holding fake conversations. Most of these practice sessions tend to be about random subjects like stripes on bees or why the ocean is blue, because although he wishes his siblings the best of luck in their love life, Saikou emphasizes the importance of sincerity in talking with another. He says that sounding boring and dishonest is always worse than being awkward.
