On the planet Zarion, children are trained from birth to become interstellar warriors. Raised in this unforgiving environment, Kairo stands at the very bottom of the system: Rank F. In a society where strength and rank define your worth, no one expects anything from him.
When he’s finally assigned his first mission —a simple, low-risk operation— no one anticipates anything remarkable. He’s just another rookie completing a basic task.
But Kairo has other plans.
As he travels to endangered planets, facing increasingly powerful enemies and challenges that test his very soul, he will prove that even from the lowest point, you can rise—if you’re willing to give everything.
Because even the weakest can become the hero who saves worlds.
