Ojou-sama Sousamou

Five girls—Miyuki, Reika, Youko, Nina, and Kimiko—receive a threatening video tape from an unknown source. They are wealthy and have enrolled at a school where police are stationed to protect them. Kimiko objects to being confined and persuades the others to deceive the officers into leaving. Shortly after the police depart, the girls encounter three armed terrorists. The situation spirals into a chaotic sequence as they try to stop the attackers.
