Just a few things, I'm pretty sure that Mitakihara doesn't have a forest in it. Mitakihara city is a futuristic concrete jungle, there might be one way outside of town but... I just thought that was weird. Also, Kyuubey never talks to people with the respect to use their last name and n honorific. If you remember for the show he always called them by their first name. "Make a contract with me Madoka." Like that. Also, I feel like Kyoko would fight back more? Idk. Plus a red tent in the middle of a forest doesn't allow for that much camouflage.

Otherwise I think you are doing good, you seem to have a plot line going, I imagine what is in those red viles is probably blood, perhaps blood of innocent humans? Oh and the POV switch was fine, not confusing at all. Also, have a bit more confidence, sure your story ain't perfect, but everyone's story has a flaw here or there usually. Keep it up! I hope to see some more chapters. :)

This looks interesting! It was short but thats fine for a prologue ;) Subscribed

This seems really interesting! I'm excited to read more of this. I find that a good way to find names for characters is to google them. For finding a Japanese name google Japanese names and meaning. It helps with finding first names at least. It unfortunately can't help with last names, but since in Madoka Magica the characters have a first name for their last name as well you could probably get away with that for your OCs for this story. Hope this helped! Btw, the prologue didn't seem too rushed.

Wow. Talk about a teaser. i must say I like the idea and I am insanely interested to see where this is going to go.

No critique at this point. it wasn't very long and I saw no apparent mistakes in what you have written already.

I eagerly await your next chapter.

Hmm...
I am somewhat intrigued by this. However, it seems very confusing at best. Be sure to explain the important things such as the relationship between (person) and (person) as well as what is going on.
This includes that individual called 'Megumi'...
Why do I get the feeling she is going to become this fanfic's version of 'Mary Sue'?

That's all I have to add for now. Good luck with this!
