Her name is Miakoda,( so she can have a nickname of Mia or Koda, whichever fits) and it means "power of the moon". As you guessed by the meaning of her name she is a champion of the moon/night. Her human appearance would be this: Tall and thin with slightly tanned skin and short black hair, in a "boy-like" cut with a side fringe that covers her left eye. Her eyes are slightly narrow but quite wide and are a purple color. Her markings only show in the moonlight/ at night and glow brightly. She can change into her wolf form at any time she pleases. In her human form she wears clothes that look similar to our time. A tight black tank top that shows her belly, it is slightly torn a the bottom. Blue shorts (about two hand lengths above her knee) with a thick belt that holds a large silver knife and a small brown pack containing essentials she has. her legs are bare and she wears flat, tight, ankle length boots.
She acts like a rugged loner by first appearance. She can be extremely aggressive if she's threatened, but this does not make her foolish. She is very tactical and a good fighter. At first she may seem distant and cold, hateful almost, but at heart is very kind and if you befriend her, her loyalty will be boundless, she will put her life on the line for somebody she cares for without hesitation. She can be stubborn and unwilling to do things if they do not suit her.
Her past is mysterious and nobody knows too much about her real wolf family, but it is known that she was adopted by a human family in a small village. They were unaware of what she really was. Nobody knows why she left her wolf family and if they're still alive, but her human family were killed, People in her village said that she was the one who killed them so she ran away. She's never told anyone.
