Hanako (ハナコ)
Hanako San is a Japanese urban legend about the ghost of a young girl that’s supposed to haunt school toilets, opening and closing doors and scaring anyone who enters the bathroom, knocks on her stall, and calls her name.
Twenty years ago, when a wave of stories of ghost-sightings swept through the nation’s school yards, one tale in particular, “Hanako, the ghost in the toilet” almost achieved the status of a national phenomena.
Every child had a “Hanako” story to tell. The stories, of course, are many and varied but every schoolchild in Japan, at one time or another, has stood in dread and anticipation as he or she ventured into the school toilet alone.

Kashima Reiko (カシマレイコ)

That way you will be saved.

Aoi Kami and Aka Kami
Aoi Kami or Aka Kami, a male ghost who waits in the last stall in the girls’ bathroom. Anyone entering the bathroom hears a voice asking, “Which do you prefer, the red paper or the blue paper?”. If they pick “red,” he kills them by slashing their back or neck repeatedly with a blade, to make them look like they’re wearing a red cape. If they pick “blue,” then they’re killed by hanging.
He’s known as Aka Manto (red cape) and Aoi Manto (blue cape), Aoi Hanten and Aka Hanten, Aka Kami (red paper) and Aoi Kami (Blue Paper)
There is also another similar version :
A lady heard a voice saying, "Do you want red paper or yellow paper." The lady replied "Yellow" and had filty stuff poured on to her. She went to a police station to make a report, the police lady stationed there thought it was the work of a psycho and decided to check on the toilet.
When the policewoman failed to return, her colleague went to the toilet to check on her, only to discovered that the woman was lying on a pool of blood - Dead.
Her answer was "Red".
In red paper, blue paper and white paper, depend on what you choose, you will get either a bloody hand, bluish hand or a wet pale white hand reaching out for you.
