Momo es una joven que ha crecido en la gran ciudad. Sin embargo, tras la prematura muerte de su padre, deberá moverse con su madre a una vieja casa familiar en una remota isla. Allí, el tiempo parece haberse detenido: viejos palafitos, sacros claros circundados de árboles, campos labrados laboriosamente en las colinas... Sin que haga falta remarcarlo, Momo no se siente exactamente entusiasta con su nuevo entorno. Y más que por ninguna otra cosa, su corazón se resiente de la carta a medio acabar dejada por su padre. Una carta que sólo contiene dos palabras: "Querida Momo...". ¿Qué iba a decir papá? Un día, explorando el ático del viejo caserón, Momo encontrará un polvoriento y vetusto libro. Desde ese momento, algo realmente inesperado comenzará a sucederle...

Ouran Academy is a prestigious school with most students coming from wealthy families. One of the few students who comes from a modest background is Haruhi Fujioka (Haruna Kawaguchi). Through unexpected circumstances, Haruhi Fujioka ends up joining the male "host club," while hiding her gender. Friendship and love grows between Haruhi Fujioka and the male "host club" members.

In the year 1716 a mysterious epidemic stickens men in the country of Japan, dropping the population of men to 1/4th of its prior state. With the drastic reduction of men, the gender roles have become reversed in Japan. Woman become the dominant members of society and males are sought out for the ability to produce children. A young man named Unoshin Mizuno hopes to marry childhood sweetheart Onobu, but due to class differences realizes this is almost impossible. To raise his social status and also save his poor family, Unoshin Mizuno enters the Ohoku (inner chambers of the Shugun's castle) and attempts to vie among 3,000 other men for the affection of the female shogun. What Unoshin Mizuno quickly learns about the Ohoku is that the men there are all beautiful, but highly ambitious and conniving. In this environment, the 7th shogun Tokugawa passes away and the new shogun Yoshimune Tokugawa takes the thrown and enters the Ohoku.
