東京都世田谷区成城。都内有数の高級住宅街に豪邸を構える「紫雲寺家」。 7人の兄弟姉妹、特に5人の美人姉妹が有名となっているが、長男の男子高校生・新は姉妹にタジタジの毎日。 「もし自分に姉妹がいなかったら…」と、ついそんな妄想もしてしまう日々の中、父親から衝撃の事実を告げられて…? The love between brother and sister. The love between man and woman. That which is most forbidden is most unyielding. The two sons and five daughters of the Shiunji family shine like brilliant gems, each with intelligence and beauty in equal measure. And with the pedigree of their wealthy father behind them, how could they not be the talk of the town? Eldest son Arata has spent his life being tossed around by the whims of his colorful sisters, yet a little teasing won’t stop him from valuing his family over anything and anyone else. But when his youngest sister turns fifteen, their father reveals a long-hidden secret of the Shiunji “siblings” and knocks Arata’s world off its axis.
