Moyako Konoe

A girl that was asked by her little brother to marry him when they were young. From that time, Moyako decided that her little brother was a complete pervert who was obsessed with her. Now that they're both teenagers, Moyako is convinced she needs to "rehabilitate" him. However, it seems that the "perversion" is entirely in her imagination, and she can't seem to help turning completely innocent situations into creepy ones in her mind.
