Teen Exorcists Give The Devil A Helluva Time In Arizona (VIDEO)

Most women have to ward off horny creatures on a daily basis, but the one that Phoenix teenagers Brynne, Tess and Savannah contend with isn't a high school quarterback, or a fist-pumping Jersey Shore wannabe -- it's the devil.

That's because when the trio aren't shopping, practicing karate or singing musical theater in local productions, they're performing exorcisms on people who've found themselves demonically possessed.

"We're just normal girls who do something extraordinary for God," Brynne, 17, told ABC Nightline. "After seeing an actual exorcism in person, led by us, you will walk away with no doubt, whatsoever."

Brynne, a home-schooled redhead who competes on the beauty pageant circuit when not circumventing Satan, is considered "the enforcer" of the trio of teen exorcists, while Savannah, 20, is reportedly the more compassionate one. Tess, 17, is the "middle man" because she can play both good cop and bad cop in dealing with demonic entities that the girls run into on an average day.

"There is a war going on every day, being waged against us," Brynne told ABC Nightline. "Satan hates us. We know how the enemy is, we know what he's attacking and we can fight back."

How did Satan learn of their presence?

Well, exorcising is a family tradition for Brynne, whose dad, the Rev. Bob Larson, claims to have performed more than 10,000 exorcisms in the last 30 years, many of which have become popular YouTube clips among believers and non-believers alike because of their over-the-top nature.

The elder Larson believes 50 percent of the population is affected by demons in one way or another, and the girl squad fights Beelzebub head on with holy water, Bibles and crucifixes, Newser reported.

Larson gives the teen devil defeaters hours of training each week and the girls have exorcised dozens of people already in between trips to the mall, classes and karate practice. In the process, Tess, is already a self-described expert in identifying a possessed person.

"One of the tell-tale signs of demonic possession that Hollywood gets right is the eyes," she told Anderson Cooper. "The pupils dilate sporadically... You look in someone's eyes, and after the [exorcism] training, you can see the evil."

Tess first "saw the evil" and allegedly performed her first exorcism on a 15-year-old friend at a sleepover who had complained of "splitting headaches for no reason" (an apparent symptom of possession). The girl in question was said to have been a strong Christian who had recently wandered away from God.

Although the "God Squad" is getting offers to be in a reality show, the girls are also getting criticized by other demon fighters like the Father Edward Beck, a Roman Catholic priest, who told ABC Nightline that he believes that the girls are "unqualified" and "unprepared" to perform exorcisms. He said it could be dangerous for them, as well as their clients.

Larson and the girls' exorcism sessions are not free, and he insists that one session almost never does the trick.

"We have to fund what we do," he said.

However, skeptic Jim Underdown of the Center for Inquiry Los Angeles, a skeptics organization, said atheism is a much cheaper solution to demonic possession than exorcism.

"The only people who get possessed by demons -- and subsequently cured -- are those who believe it's possible," he told The Huffington Post. "You never hear about it happening to atheists."
