Tomoe Hasumi

She is a mechanical doll, created by a scientist to recreate his fallen wife. She made her more perfect, being that of a kitsune. However, while he was able to download much of his wife's personality and memories into her mind, she showed signs of independent thought and even behaviors that his wife never had. The scientist deemed that part of his work a failure, he did in creating a new companion that could share his life with. Years pass and the scientist is a bit older. He still maintains and improves Tomoe's design. She now is a sentient being, able to think and feel on her own.
