Moyako Konoe, a high school girl, becomes convinced that her younger brother Akira is secretly a pervert with a sister complex after he innocently said as a child that he wanted to marry her. Taking this statement seriously even years later, Moyako believes it is her responsibility as an older sister to "rehabilitate" him and prevent him from becoming a deviant. However, most of Akira's behavior is completely normal, and the situations Moyako interprets as perverted are usually misunderstandings created by her own imagination. Everyday interactions between the siblings are repeatedly misinterpreted by Moyako, leading her to take extreme or absurd actions to avoid what she believes are Akira's schemes.
