Sumire has a bright personality, and a rough past. She was born in a rich family, for her parents were owned by millionares. They knew someone that wanted a husky and kelpie mix, so they gave her away. The family loved her. But they wasted away much of their money. And they went bankrupt, and could no longer afford her. Since they lived near the woods, they released her there. And always came back to visit her. She learned how to live a life in the wild, and easily adapted to it. She loved the freedom. Once the family offered to take her back, she reluctantly denied it. This was her only sense of a carefree life, and her only feeling of freedom. The family accepted her choice, and understood her desicion. But they continued to care for her. She hunted prey and frequently ate the food they fed her. She figured that her life couldn't get any better.
