In the midst of a galactic battle between the scion empire and the infested indigos. The empire sends its soldier to fight and hold a moon base against the endless waves of the lifeless creatures.

You are running low on ammo, soldiers are dead or dying, and the enemies are everywhere.

A young orange hair girl in a flying armor lands to you.

“Get up soldier! We’re not done yet!”
