Mashiroiro Symphony: The Color of Lovers

ましろ色シンフォニー -The color of lovers-

When the all-girls Yuihime Academy runs a trial merger with the nearby co-ed Kagamidai school, second-year Shingo Uryuu transfers in for a ten-month experiment alongside his stepsister Sakuno and a handful of other boys. Most of Yuihime resists the newcomers, none more openly than the principal's daughter Airi Sena, who wants the male students gone. Shingo settles into the elegant campus and slowly wins over the girls around him while the merger's fate hangs in the balance.
