Yuko Aso, wearing a leotard, was performing her rhythmic gymnastics ribbon routine alone in the gymnasium of Shiroyama Minami High School. Hitomi Aoyama, wearing a sailor uniform, was gazing at her with a passionate gaze. Yuko was a new female teacher who had come to fill in for a vacancy at the prestigious Shiratori Women's College of Physical Education, a gymnast with a high level of rhythmic gymnastics.
