Standing of mankind

The last thing I remembered was saying good night I love you to my wife before falling asleep, that was the year 2014. I awoke all alone in a world where once great cities now lie in ruin and Demons walk the earth. I did not awake helpless but with a great knowledge to do battle against the demonic horde. While I slept I was trained in several of the United State special forces ways as well as the ancient Bushido and Shinobi. I believe that once this evil has been eliminated I will again fall asleep and awake next to my wife but for now, I just must survive.
