Animosity Cosplay is a group of 20somethings based out of Central Michigan. They met in college and with their nerd powers combined started cosplaying the Akatsuki and performing skits at local conventions.
Since then Animosity has spread out, both in what they cosplay and where they're located - some members in Florida and others on the other side of the world, but they still get together at their hometown cons to nerd it up and generally party down.
