I'm Quitting Heroing

After successfully saving the world, Leo, the most powerful hero in existence, finds himself unwelcome in the very human realm he fought to protect. His overwhelming strength has made him an object of fear rather than gratitude in a society that now enjoys peace. Cast out and exiled by those he once defended, Leo is left without a place to call home and must search for a new purpose. His unlikely destination is the Demon King's Army—the same force he recently defeated. Now in ruins and desperately needing reconstruction, the army is plagued by severe logistical issues, including crushing workloads and deep financial instability. Stepping into this chaotic environment, Leo begins applying his extraordinary abilities not to destroy, but to rebuild and streamline their failing operations. During his efforts to revitalize the army, Leo crosses paths with Echidna once more. Driven by lingering questions, he finally asks her the true reason behind the demon army's original invasion of the human world. Her response reveals a startling and unexpected truth that completely reframes everything he thought he knew about the war he fought.
