Judgement of Angel

IT BEGINS

Story About...

In a world where humans and demons are engaged in a boundary conflict,
it is said that every 500 years, an army of angelic beings appears from
the heavens and attacks and destroys any civilization in sight to
reset the progress of the age in order to prevent civilization from
advancing and a major war from occurring between humans.
Today, it is the dawn of a world of warfare, where these three forces
- mankind, demons, and angels - will clash with all their might.
What will become of this world, of humans?
