Well, I really liked it. I thought it was a very interesting perspective on the concept of shiny Pokemon, which I had always before seen as just a variation in color. I liked how the events that came as a result of Hidma being an omen were directly caused by the idea of him being an omen. It certainly provided a nice look at the group psychology of Houndour/doom. I also thought it was a nice touch how you capitalized "Human." It seemed to reduce the size of the barrier between people and Pokemon.
I did spot one glaring grammatical error:
<overreaction> Tense switching! Unfogivable! </overreaction> (OMG )
"Give" should be "gave."
I wouldn't say this is a grammar mistake, but it feels awkward:
For one thing, it's an awfully long sentence. And, the quick reusage of the word "again" doesn't help the flow much.
Nitpicks aside, great job!
I want to change the story lol hidma one day betrays her gets a nerf gun and one day shot midvma's and then dies...
