Actually, I'd say she's a pretty even mixture of all of the above, except the loli bit.

I'd probably say cute klutz wins out

Poor girl's woobierific. She makes one decision and is caught in a veritable firestorm of crazed clothes ripping and strange codewords, with no means of escape. And every so often, which is quite often indeed, she loses complete control of her own body, which destroys everything is sight, including her cosplay!

Already did this one back in "Character Traits":

Sarah is a .

Peter's the Unlucky Everydude type linked to in the article. Quoting the article's "Checklist" a magical girlfriend is "beautiful, kind, domestic, and utterly and eternally devoted to him." I consider Sarah good-looking enough to check that box. She's seemed very nice, if rather stressed out, and lets face it, her "inner beast" is a puppy, so kind gets checked off. Under "domestic," I'm just going to put down "wolves eat raw meat" and consider Sarah to be "domestic enough" automatically.

"Uttery and eternally devoted" is the last category, which is a heck of a long way of saying "thrall." Peter's original "girl trouble" was Butch, or specificallly Butch's "claim," but Sarah fixed Peter's girl trouble. You may not agree that "thrall" represents that form of devotion shown by magical girls, but when you start looking at how Sarah behaves with Peter in wolf form, it starts tipping a whole lot of the side of "close enough." So devoted gets a check in the box to round out magical girlfriend.

Now as for the format of the series, we're getting an introduction into the werewolf culture. On the one hand, Sarah is an outsider for whom this is all new, so she gets a strong argument for main character. On the other hand, Peter's uncutured enough that he didn't know how thralls were made, so he'd probably have to "relearn" enough to explain things to the audience seemlessly. Except that now he has a magical girlfriend for whom he can ask other people to explain stuff for, all while looking as if he knew it but couldn't verbalize it well.

EDIT:

If Sarah had been a closet furry, she probably wouldn't have turned into a seven foot tall mammary mammal. You see, during Sarah's initial transformation, she didn't know what was going on, she just felt POWER! POWER COURSING THROUGH HER VEINS! POWER THE LIKES OF WHICH SHE NEVER DREAMED! Stretching twoards the sky and crying out in exultation would have been the only natural thing to do, and the only recent experience she would have had to compare with the transformation was her night with Peter, actually the cause of the change. She didn't worry, or think, or fight the first transformation and so it had more to take effect, especially the way she was stretching and urging herself onward in confused passion. A closet furry, on the other hand, often has quite an imagination, often pretending they have "keen animal" sense or reflexes. When the energy of the change takes place, they often scurry into the underbrush before the animal instincts even begin take hold. They are the first among any thralls to notice new hair growing, and excitedly stop to admire the changes taking place. This focus on external features slows the "rush" of transformation, resulting in a new were-specimen, sometimes with keen senses and a beautiful pelt, but most otherwise poorly developed. Their focus is all over the place, wiggling ears, tail, keen senses, new feet, and they bring too many ideas over from human side. Many don't even have the instincts to walk on four legs, and rest assured, most of them do have the "appropriate legs" for the species. With Sarah's transformation was focused on power and base emotions, with wolf almost as an afterthought, but alt-Furry Sarah would focus on the wolf first, or maybe even just the fur. If the were-form is affected the initial perception, as I expect a nervous crowd-shy Peter's might have been, then alt-Furry Sarah focusing on another mammal while transforming into a wolf could have, if not disasterous, at least really freaky-looking results. Imagine, if you will, a "cabbit" werewolf. Semi-hypothetical indeed.

I think that none of these really apply, as Sarah is almost becoming an inversion/subversion of all the main tropes.

This is what happens after the words "happily ever after" are supposed to splay across the screen. Or maybe, after the nebbish-y hero finally gets that first kiss or whatnot. (Remember how damned long most of those anime series take to get the characters to kiss, or admit they're in love, let alone jump in the sack? {and with that, they never really jump in the sack, do they?}).

It's like a romantic comedy-harem anime-magical girlfriend if done by...
