Yoon Garam is a sadistic human weapon born after North Korea's drug experiments. She killed everyone at the research center and escaped North Korea alone. After being released from the juvenile detention center, Yoon Garam goes to school to take revenge on her stepfather who took her away, and to go hunting for her own sadistic pleasure.
