Yukuo

Yukuo is a loner scientist. Her parents died in a car accident when she was very young. During that time her mother was pregnant. She was so distraught she decided to work on a project. For years she made prototype after prototype trying to create a sister from science. One day she succeeded. She made her a new sister and she named her Dakuo. Yukuo was happy again and sworn to protect her sister no matter what. She still hardly left the house other then to pick up Dakuo from school.

"Don't worry Dakuo, i'm here for you."
