During their childhood, Akira, the younger brother of Konoe Moyako, professed his wish to wed her. This statement had a profound impact on Moyako, making her believe that her sibling possessed a twisted nature and an unhealthy fixation on her. In present times, Moyako's goal is to "correct" her brother's behavior as they enter their teenage years. However, her paranoid mindset often transforms innocent situations into depraved ones, making it hard for her to distinguish between reality and illusion.
