Mashiro-iro Symphony: The Color of Lovers

Some girls have a tendency to become irritated when boys unexpectedly enter locations where they have never been permitted before. Therefore, when it is decided to combine the prestigious Yuihime Girls' Private Academy and the coeducational Kagamidai Private Academy, everyone wishes to take extra precautions to prevent trouble while bringing the two Private Academies together. Therefore, a method is devised in which a group of test guys will be introduced into the Girls' Private Academy first, rather than just putting the Kagamidai lads into the Yuihime girls' school all at once. As a result, the lionesses of Yuihime, who aren't exactly welcoming him with open arms, end up using poor little Shingo as a sacrifice lamb. Will Shingo be able to escape Yuihime's estrogen-filled abyss? Can the girls develop a better openness to the boys? And how long before something involving pants sets off conflicting feelings, sparks fly, and the war of the sexes erupts?
