Plane Super Warrior

The "orphaned second generation" whose parents both died picked up a half-dead alien with a big head and took over a job - brave young man, fight for the love and justice in your heart! (Wait, it seems like something strange came in?) Well, the real story is... "There are still ten years left. If you fail, this planet will turn into dust in the universe..." "... God knows if there's an alien poorer than you." Due to his deep resentment against the impoverished aliens, a certain man was forced to embark on the path of savior.
