Kousoku Angel Engine BGH

21 century, Japan - this world had been dominated by the three types of organisms. Humans, Angels and Devils. The angel is the highest in hierarchy, the devil is to be hunted by angel. Human beings who know the current state of the devil's hunting embark to make a settlement with the angel's and the devil's in the name of "love and peace".
