English translation[]
The giant mecha was destroyed!! The enemy base got engulfed in flames!! Everything is over... I left the monster planet and headed back to Earth. "I guess I'll sleep for a bit." When I switched to the autopilot mode, I was about to rest... Something is not right! When I looked, the alien I thought I had killed earlier had split up and surrounded me!! "You're still alive! Oh... wow!!" I ended losing my life because of that sleep.
