And look! It has grown wings! It must be close to maturing.
Young dragons are relatively defenseless. They are born with relatively soft scales, which are shed and replaced with harder ones as the hatchling matures. Once a hatchling’s wings grow in, it marks the beginning of maturation. At this point they are often capable of hunting on their own and are usually left alone by their mother.
Chevalier is a chivalrous knight with a tragic past, or so he claims (which may or may not have led to his current frozen state). Despite being smaller than most of the girl blacks, he takes it upon himself to protect them from harm. He tries to conduct himself with dignity at all time, and despises those that pick on the weak. Some of the girls find his lofty airs and angsty bearing annoying, but most of them (and Hanako) think he's pretty hot.
