Banshees are the result of murder. It's believed that sometimes a Ghostly can form away from their original bodies and upon finding said body, will recall their former lives. In particular, the last moments. The Ghostly will then evolve into a Banshee and begin hunting the person who killed her. Sometimes, this will also occur if she finds her loved ones murdered.

Unlike other Ghost Pokégirls, Banshees have but one purpose: finding the murderer responsible. Once this is accomplished, she will depart for the afterlife.

However, many times, finding the killer isn't always easy.

As such, she will often track the spiritual signature of the person as best as she can, but will ask for aid from Megami, Sorceresses, other Ghost Pokégirls and even Youma and their evolutions. If any of these Pokégirls attempt to stop her or convince her to stop pursuit of the killer, they will be ignored and the Banshee will look for someone who will help.

If they find the killer, they will attack immediately and without mercy. Even if driven off, she will simply return the next day to attempt again. Only an exorcism, admission of guilt to Megami or law enforcement agency or the murderer's death prior to her return will quell her anger.

Banshees become truly troublesome when they are either unable to exact her revenge within 10 days of finding the murderer or if the murderer is killed before she can find them. She will them begin to haunt the murderer's dwelling, pestering and attacking all within relentlessly and using Wailing and Cacophony routinely, until she is exorcised or otherwise appeased. This generally includes proper burials and the murderer either going to jail or at the very least, being listed as a murderer in an official document.

Banshees will often listen and respect to Megami, unless the Megami tries to get her to leave without making efforts to at least rectify the situation. They will then ignore that Megami and continue their pestering until another effort to appease her is attempted by someone else.
