Gakkou no Kowai Uwasa Hanako-san ga Kita!! Minna no Hanako-san

There are lots of horror stories, but "Hanako-san" is one of the most popular ones. Is it just a rumor?
When wet footsteps are heard or there is silence during telephone call, it may as well be Hanako-san. But she also helps children who are in dangerous situations. She has youkai rivals called Yamiko-san and Yomi-san, so her life is never boring.
