In Indian mythology an Acheri is the ghost, or spirit, of a little girl who comes down from mountains and hilltops at night to bring sickness to humans, particularly children. As the Acheri wanders, if its shadow falls upon a child they will become terribly ill. The only defense against an Acheri was thought to be a red ribbon tied around one's neck.
Acheri appears as the boss of the bronze level of the Ueno Mirage instance. By defeating a wave of smaller versions of her, a boss version will appear. She is unique in being the first mob in Imagine capable of inflicting the Blindness ailment.
Shin Megami Tensei: Strange Journey
"A ghost of a little girl in Indian lore. She brings sickness to children. She comes down from the mountains at night and spreads disease by casting her shadow over children. A red ribbon tied around the neck protects children from her."
Although the series attributes and presents this demon as being from Indian, i.e. Hindu mythology, in fact, the Acheri is an entity from Native American mythology.
