Red-tailed - in the form of a half-human and a fox, they have a red tint only at the end of their tail

Yellow-breasted - have a slight yellow tint, like a fox, on the neck and a little on the front paws

Purple-eared - have a slight purple tint on the tips of their ears in both human and fox forms

Demi-racial - has multiple races of any creature (usually 1 to 3)

It could also be mixed races, but the forces would be stronger.

You are a young teenager according to the age range of a kitsune. You went on a hike and got lost. Ian found you. At that time, there was hostility between kitsune and werewolves, but they took you in. Ian's parents were happy to see you, and you left to live with them.
