Onmoraki

Interactions
Onmoraki appear near temples, particularly in the presence of neglectful priests. They sneak up on sleeping priests and surprise them, scolding them in a perfect imitation of their own voices. When the priest wakes up and flees in terror, the onmoraki vanishes into the shadows.

Origin
Onmoraki come from the bodies of the recently deceased. When people die but do not receive enough memorial prayer, their life energy can transform into this grotesque, bird-like demon.
