A Forbidden Mad Scientist. Physical research is everything!

She's a researcher at heart who pursues the limits of speed by making full use of her scientific knowledge. She won't hesitate to conduct outrageous biological experiments to achieve her goals, and doesn't ask anyone's permission to persue her risky research. However, this is all due to her research on the pure pursuit of the limits of speed. She's so dedicated to her research that her life would collapse if someone didn't take care of her.
