NEW YORK — Buffy, begone.

Almost two years after 9/11, the TV biz is birthing a new breed of mystical show giving everyday people — mostly ambivalent young women — the power to correspond with the universe and do the right thing.

Don’t expect the sugary religious tone of “Touched by An Angel” or the pagan grace of “Buffy the Vampire Slayer.” Not even close.

This frosh crop is about spirituality.

“If there is any lingering shadow of 9/11, it’s the desire to believe we are all one human system,” says Todd Holland, who is co-creator and director of “Wonderfalls,” set to bow midseason on Fox.

“Wonderfalls” and another new primetime drama, “Joan of Arcadia,” bear striking similarities.

“Joan” has the 8 p.m. Friday slot on CBS’s fall line-up.

Both reinvigorate the Joan of Arc myth — “Arcadia” much more so — and have protagonists who are moody, complicated young woman asked by God in one case and by inanimate objects in the other to accomplish a series of tasks for the greater good — on faith alone, no questions asked.

“There’s something in the zeitgeist right now that people are thinking about this stuff. Sept. 11 left a residual spiritual awakening,” says “Joan” creator and exec producer Barbara Hall, who most recently exec produced CBS’s “Judging Amy.”

There’s also the ever-present pressure to appeal to the younger demo. From this vantage point, it’s hardly magic that young heroines attuned to the invisible would be a theme attractive to network development execs.

Fox, which is threatening to take the key 18-49 demo away from NBC, has three of these shows. In addition to “Wonderfalls,” set for midseason, there are “Tru Calling” and “Still Life.”

“Tru Calling,” airing this fall in the key 8 p.m. Thursday slot opposite NBC’s “Friends, centers around a young woman who discovers she has the ability to start a day over again in order to prevent someone from dying.

“Still Life,” skedded for midseason, tells the story of a family devastated by the death of a son. What the family doesn’t know is that the son is able to communicate with one of his brothers, who in turn serves as a medium to the rest of the family.

Fox exec VP of programming Craig Erwich says issues of the afterlife, spirituality, faith and belief are just as resonant for young auds as they are for older viewers.

Erwich says there was no decision to pick up the three shows because they fit a certain metaphysical theme. Still, he agrees that 9/11 sparked an unease that can’t easily be fulfilled.

“There was a cultural examination of death and what is greater than what is in front of us. People took a step back and pondered the greater meanings of things, and in a pretty vigorous way. These shows are more about what is beyond us,” Erwich says.

HBO helped pave the way for such shows with its hit series “Six Feet Under.” In mid-September, the paybox is again turning to the metaphysical with the original series “Carnivale,” a story of magic and supernatural powers set during the 1930’s depression.

Like her counterparts at other networks, HBO exec VP for original programming Carolyn Strauss says there is no doubt that in times of uncertainty, people look to the invisible for hope and solace.

It also makes, she and her counterparts hope, for good storytelling.

Showrunners say they were initially dubious themselves about being picked up by the network.

“I know when I first started pitching it, it raised a lot of eyebrows. And I thought, you know what, I’m never getting anywhere with this,” Hall says.

Hall’s new drama, which has generated plenty of buzz for its A-list cast and unusual storyline, stars Amber Tamblyn, Joe Mantegna, Mary Steenburgen, Jason Ritter (John Ritter’s son) and Michael Welch.

Hall’s Joan is no angel, and without a doubt no Buffy. Rather, she is an imperfect teenager to whom God appears in a series of random people, from a hip, cute boy to a cranky school cafeteria worker.

The deal? God wants Joan to follow certain instructions, but she can’t ask any questions.

Hall has drawn up a list of commandments for her show, including that God can never directly intervene. Also, Joan can never ask “why?”

In the pilot, God tells her to get a job at a neighborhood bookstore. She ultimately does so, and it so inspires her wheelchair-bound brother, that he decides to stop hating life and get a job himself. In turn, her family can begin to heal from the accident which left Joan’s brother paralyzed.

In “Wonderfalls,” lead character Jaye Tyler (played by Caroline Dhavernas) works in a tacky souvenir shop in her hometown of Niagara Falls. She’s an apathetic college graduate with a lesbian sister, a therapized, feel-good mother, an outspoken father and a sarcastic brother.

Just like that, a disfigured lion suddenly starts talking to Jaye, giving her instructions. Like Joan, she eventually gets with the program and, in the process, recovers a stranger’s stolen purse, helps a UPS driver hook up with a nurse and finds a babe for her sister.

“Wonderfalls” is much quirkier than “Joan.” Holland created the drama with Bryan Fuller, who also created and wrote the first episodes of Showtime’s new series, “Dead Like Me,” which tells the story of a young woman who dies and becomes a grim reaper.

(When Fuller decided to stick with “Wonderfalls,” Showtime hadn’t yet picked up “Dead.”)

“What is at the core of the show — do you stop the car at the scene of an accident, or do you drive on? In reality, we all drive on. All of us,” says Holland. “Our heroine is not given that choice.”
