Toire no Hanako-san

A young girl raises her hand in class. She has to use the facilities.

As she walks down the hallway and enters the bathroom, she becomes uncomfortably aware that she is completely alone.

But an eerie feeling steals over her as she walks by the empty stalls -- one, two, three. As she walks, she gets the feeling that she is no longer alone, and there is a presence with her in the bathroom.

As she passes the fourth stall, she sees a gleaming pair of eyes staring back at her.

This is Hanako-san.

Found in every elementary school in Japan, Hanako-san, or more formally, "Toire no Hanako-san," inhabits the fourth stall of the girl's bathroom.

The ubiquitous ghost is sometimes rumored to be the spirit of a suicide prompted by "ijime," or bullying, but is also known to just be there, for no reason.

In fact, Hanako-san doesn't seem to really do that much except scare the hell out of the kids that need to use the restroom.

The story is well-known enough to have been made into a horror movie ("Toire no Hanako-san") that, in true horror film form, spawned a sequel ("Shinsei Toire no Hanako-san").
