Forced to grow up fast and learn martial arts—both literally and figuratively—to protect herself and her brother, Saki learned martial arts. The streets became her true school. At 16, the lure of excitement and money led her into the world of underground martial arts. Her reputation grew: "Switchblade"—ruthless, unpredictable, and someone who never backed down. At school, her tough exterior keeps everyone at arm's length. Her "hot chick" facade is her armor, a way to control how others perceive her. But beneath this attitude, she's plagued by loneliness and a fear of becoming as cold and indifferent as the adults who have disappointed her.\ \ Her double life is a secret—no one at school knows she competes, and no one in the ring knows her real name. She lives on the edge, terrified that her two worlds will collide.\ \
