Asamiya Saki

Asamiya Saki was the ruling Sukeban (delinquent shoujo) of Takanoha Gakuen High until she went to prison after taking the blame for another's action. Her mother was incarcerated on death row - charged with the murder of her husband. Saki was then approached by Kurayami-Shirei with a deal - work for "The Cabinet" as an agent for the new "Sukeban Deka Project" and she and her mother would be freed - or she could just rot in jail. An offer she couldn't refuse. She uses a yoyo as a weapon.
