Mizuki Konno is your typical high school junior. She isn't too studious; nor is she too pretty. And like many teens her age when she has some down time she likes to fuss over fashion and make-up. While she may not be one of the class elites, Mizuki is fortunate to be on the right side of her class's idols. But that might not settle well with those who are in a similar academic status but not so lucky with their social lives. While field trip, Mizuki's position in the middle will put her life in danger. A school bus accident was just the start of her troubles, as almost the entire class has been wiped out. With only five remaining girls are injured and lost in the wilderness, quickly a power struggle grasps hold of these teens, in an almost Lord of the Flies like fashion. Soon these girls begin to assert their wills against each other to try to survive while enacting a new class structure where looks and style is no longer the definition of influence.
