Summary: Starting out as a troublemaking delinquent ever since her youth, Saki's history of provoking fights or causing trouble whether she did it or not puts her on another delinquent's sight named Reiko Amabuki. It didn't take long before they became partners and close friends, eventually creating an all-girls biker group who dreams of taking over Kyushu, and then the entire nation, one day. Assigned as a squad leader and second-in-command, Saki would lead and support her group all the way to victory, but sadly, that dedication puts an early end to her life during a game of chicken against a rival biker gang, Korosuke.
Her dream of taking over Kyushu one day, however, would not end just because she died, for she was raised back from the dead many years later. Initially ticked off and at odds with Kotaro and Sakura, witnessing the latter's "guts" and realizing how viable being an idol singer would be in conquering Japan changed her mind, leading her to take the mantle as the leader of the newly-instated Franchouchou.
