Badass Demon Killers

So basically there's a city and odd misc. things start happening maybe certain animals start dying off and during all this certain people start developing psychic abilities then one day a portal to hell opens in the sky above and demons and monster come down and wreck havock. Then the characters basically turn into badass demon hunters.
Rules:
It just has to be understandable and the post length just depends on the context of the rp. I just want this to be pretty casual.

Ooh! I'm in :D

Cool, do you want to do this over pm or on a thread?
