Akuma

The Original Earthlings
The Akuma are an ancient race that inhabited Earth millennia ago. They lived a peaceful life in small groups around the world. This all changed the day "angels" fell from the skies and conquered the peaceful race. Our idea of Angels and Demons stems from the divide between these two groups. As the years went on, the Akuma dwindled in numbers until only a few remained. The last warrior among them was sealed away inside of a tomb in Egypt, only to be uncovered by Marco Diaz in the current day.
