CH00: (Gustav) Prologue

Almost two decades have passed since the end of the battle for Earth.
...yet, the battle is not over.

As a dark shadow falls over Anhsook Del Iris, three youths train.
...A princess...A gunman...A swordsman...Their worlds will collide.

Will that which was lost be returned? Will they be able to survive those hunting them?
And has humanity brought something with them...something that will bring destruction to their new home?

A dark moon rises.
