So when the decision is made to merge the elite Yuihime Girls' Private Academy and the coeducational Kagamidai Private Academy, everyone wants to take extra care in avoiding trouble while bringing the two Privates together.

Thus, poor young Shingo finds himself being thrown as a sacrificial lamb to the lionesses of Yuihime, who aren't exactly waiting for him with open arms. Will Shingo manage to survive the estrogen soaked death pit that is Yuihime? Can the girls learn to be more receptive to the boys?
