Have you ever walked alone, then hear a sound of footsteps behind you, but when you turn around, nobody's there?
Betobeto-san is the yokai of footsteps in Japanese folklore. It likes to follow a person around, especially at night, when the person is alone, and/or walking in deserted roads and alleyways. It is formless, and can only be determined by the sound that it makes - the sound of footsteps.
It is said that betobeto-san likes to follow people around in this creepy manner because it feeds on people's fear.
One way to make betobeto-san stop following you is to say, "After you, betobeto-san." If you say this politely enough, betobeto-san will accept your invitation and walk in front of you, and shall soon proceed to find another person to follow.
