Shinyori Tatsuryō Academy is a prestigious school with a long history, known throughout the nation. The protagonist, Ryo Takamiya, carries the blood of the Takamiya family—the founding clan that secretly controls the academy from the shadows. One day, he receives a request from his beloved older sister, Satsuki: to destroy three women—Asuka Kanzaki, Minato Morino, and Rumi Hasebe. His sister’s true purpose remains a mystery. However, for Ryo, Satsuki’s words are absolute. Without hesitation, he accepts the request and begins his plan to break down these three academy women, transforming them into his obedient “female slaves.”
