"Five minutes ago it was February 17!"

"Um, no, no it wasn't. What's going on?"

"If I say the word 'Kyubey' are you going to have any idea what I mean by it?"

"Not the foggiest."

"Magic exists. On February 13, you made a wish using a magical wish-granting creature called 'Kyubey,' which resulted in your becoming a magical girl. And now it's February 25--there must be some kind of time-affecting magic, I guess--I'm going to try something stupid." And she puts on a coat and goes outside, cups her hands and yells, at the top of her lungs, "KYUBEY!"

There is a delay.

A creature trots around the corner.

Emily stares.

"Do you remember it being January 25 or February 17 ten minutes ago?" Edie asks the fluff.

It's January 25 and has been since midnight.

"I remember it being February 17. Can witches and/or magical girls do time stuff?"

That could be possible!

"Because I didn't know you existed on January 25, last time, I only found out after my sister became a magical girl, which it doesn't look like she is anymore."

You both have the potential to become magical girls! What else do you remember happening?

"Well, I remember the thing she wished to fix, I remember her being a magical girl for a few days and killing two witches and asking you a lot of questions."

"What did I wish to fix?"

"I, um, got slightly murdered."

Hugs.

The wording might be important!

"Of her wish?"

Yes.

"For the time travel or for how it is that I remember and she doesn't and you don't?"

Both.

"Uh, she actually mentioned the wording and I don't think it could plausibly have caused time travel, but--" and she relates the wording, "I sort of wondered if it made me immortal, and if so what kind--but I wasn't going to test it."

I'm not sure what happened! I'll try to figure it out.

"And tell us if you do? Or will it be back to teeth-pulling."
