They dance on fire, play around corpses, eat human fresh, drink new blood. Human slaughtering is their hobby, soul collection is their job. They are always survived while sins are existed. You can't see their actions easily, but they can read your evil. If you deal with them, you will be alive forever...in the hell. To resist them, shield by courage, sword by belief, horse by honor, forward by iron will. Cross their tricks, slash their claws, raise your flag till the kingdom comes.  I know I am not always alone, angels of God---my grandfa and grandma watch me all the time, I will try to do my best to pass every day.
