In the spring of 1994, a 16-year-old girl, Katsuki Aso, was transferred from Kamiya High School in Saitama Prefecture, Japan. Strangely, she was a girl with Yin Yang eyes and Yin Yang ears and a strong sixth sense. The physical education teacher in her class, Yoshino Ichiro, made her have strange feelings. She protected Yoshino Ichiro during the supernatural incidents that happened one after another.
And those supernatural events all came from a thin, pale female ghost.
A boy with hypochondriasis and a girl with special powers gradually entered Aso's life. These three people caused Aso's fate to change dramatically. Her identity began to be questioned, supernatural events happened one after another, and secrets were exposed one after another... And what is the final outcome?
