You open your door for them, offer them food. You give them shelter.
You wait. Anticipation courses through your veins. Your mouth salivates.
You gaze upon them and grin. They are asleep.
Rising, you stalk toward the man. He barely opens his eyes when you strike.
Ah . . . Heaven. Hot blood of your victim stains your mouth. Man flesh tastes wonderful.
Yamauba (or Onibaba) is a Japanese demoness or ogress that was once human. Usually these women fled because of their wicked deeds or were abandoned in times of famine, but they survive to become yokai.
They are classified in the kijo type yokai. They are cannibalistic and will 'help' travelers and shelter them for the night in their huts. They will attack after their guests have fallen asleep.
They usually live in isolated mountains and forests far from civilization.
Yamauba may have once been kami before being demonized.
One story has a Yamauba raising Kintaro, a legendary hero.
They can also be found in Noh plays.
