Radiant Angel Dragons are known for their intuition—they always seem to know when someone is feeling down, and will do what they can to provide cheer. These dragons are curious and will poke their noses into anything. They communicate with one another by making sounds similar to singing. It is said that the golden feathers shed from their whiskers can rekindle lost feelings of love.

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.

Kagayaki tends to think of himself very highly. He is very full of himself, and has a regal personality, almost like that of royalty. Because of this, his friends don't stay around for long due to his demanding personality. Constantly requiring attention and validation, he desires to seek others out. However he does not want to seem desperate and waits for others to come to him, this tactic does not work very well and can leave him very frustrated and angry.

He always takes the position of the leader, and only gives help to those he deems worthy of it. He collects various sorts of gold, jewelry, gems, and more for his own hoard. He is very greedy and doesn't share often, even going to lengths of not allowing others even meters away from his stash. He is very hostile when it comes to his possessions, and his position as Alpha.
