Tsukasa Hinomoto, a high school student, learns from his parents that he was adopted and that his biological father is a wealthy corporate executive. His father arranges for Tsukasa to participate in an event called Marriage Royale, where young women from across Japan gather on an isolated island to compete for his hand in marriage. Tsukasa is sent to a school built for the event and resides in a mansion on the island, where he is looked after by two twin maids, Miku and Miu.
