but Midori Aoi's story started in June 2010, yours in March 2011. At a first glance, since she started nine months before you, you have to come with a little more substantial evidence than "fic with similar idea" before you start accusing her of plagiarism.

At the moment it looks more like you are plagiarizing her. (Which I doubt is the case.)

Have you or Anjilly contacted Midori Aoi? That might be a good way to clear the air, see what's going down.

But honestly, I'm not sure there's that much plagiarism going on. Your OFU is an ensemble cast affair, while hers is more centered around one character going around doing stuff. Also, it reads more like a high school thing than it does a guide on how not to write fanfics in the A:TLA continuum. I dunno.

I suggest you contact her about it first before you do anything else. That might help clear the air a bit...

No disclaimer of "fanfiction universities are Miss Cam's idea", and no trace of Midori Aoi in the Wiki or the Board. Not good.
I didn't search for similarities between your OFU and hers because I don't have the time, however.

I know that PPC and OFUs are separate entities, but effectively seems that a random girl decided to open her own OFU-lookalike. In my personal opinion, nothing wrong about that. Love for canon and good writing is always a good thing.

But pagiarizing somebody else's work is always bad.
