Isara is a red dragon who can take human form and lives at the mountain which used to be have a great dragon temple. Despite all his clan has white scales, his are red.
One day he saved a white haired girl who's going to succeed the kingdom's throne, but can't claim it until a dragon accepts her as his companion, because she carries foreign blood in her veins and her uncle does not want her as the new monarch. Eventually they get closer and he accepts become her companion.
He's kind and cares a lot about other people, but bears a great affection due his condition (having red scales instead white).
