There is one in this parking garage.

Well she will just go there then.

Actually no, that's dumb. She's going to ask the Kyubey how to successfully hunt witches and not die, first.

In the middle of each witch's barrier is its main body. This is more dangerous to confront than the familiars growing in the labyrinth but if you damage it enough the witch will die. You are faster and stronger than a normal human now and most magical girls can summon magical signature weapons and shoot energy bolts.

"How do I summon my magical signature weapon?"

I've never done it myself but it should be pretty easy if you try!

"Huh. Okay." She tries it. "Whoa!"

Her magical signature weapon is, apparently, a two-handed sword slightly longer than she is tall.

It will be easier than it looks to use.

"I sure hope so!"

You can also reconjure it if you lose it or want to wield one in each hand.

"And wielding one of these in each hand is going to be feasible? That seems...this is a two-handed weapon."

Yes, but you could hold it in one hand. Or use it telekinetically.

"Ooh, tell me more about telekinesis."

You might have difficulty picking up anything larger than an eighteen wheeler. It costs more magic to move things with more force, or bigger things.

"But I could summon like eighteen greatswords and become a whirling dervish of death."

Yes.

"Okay, that's really cool."

Tailswish!

"Is there anything else I ought to know before hunting witches?"

The door opens and somebody wheels in a gurney with a body bag on it.

You could bring potential magical girls who have not made wishes yet into the labyrinths with you, and sometimes human weapons can help a little with the familiars and even the main witch bodies.

The somebody with the gurney doesn't notice the creature. "I'm real sorry for your lo-" Blink. "Wrong room, sorry." Out he goes.

"--Oh. Um," she says when he's left. "Yeah. Edie was pronounced DOA, do you...have any experience with magical girls handling resurrected people?"

You could edit some memories with magic, but even without that many people will assume there was some mistake.

"Yeah, I'm going to not use mind-control as a first resort," she says, and then goes to find a nurse to explain that there must have been some kind of mix-up, her sister was apparently pronounced DOA but she's not only alive but conscious.

"Sorry about that," says the nurse, "must have been an awful fright, we've been so busy today -" And she takes Edie's vitals and notifies official persons.

...Emily has healing powers now. She discreetly finds a few rooms to duck into that have people who seem to recently need them to test what she can do.

It's the ER. Several stabbings of various amounts of fatal. Old lady with a broken hip. Diabetic in crisis. Baby with fever. Guy who prrrrobably has something stuck up his butt. Car accident.
