Thirteen years ago, Earth was invaded by the evil Monster Army, intent on enslaving mankind. Fortunately, a team known as the Divine Dragon Rangers rose up to confront the invaders and defend humanity down to this very day. At least, that’s how it appears.

One downtrodden mook, disgusted at this state of affairs, vows to rise up and destroy the rangers.
