I'm Quitting Heroing

A hero too strong for his own people seeks redemption by fighting for the very monsters he once defeated.

When the Demon Queen Echidna launches a full‑scale assault on humanity, the kingdom’s last hope is Leo Demonheart, a hero whose power dwarfs any mortal threat. He crushes the invading forces with ease, but instead of celebration he finds himself ostracized—people fear the very strength that saved them, fearing it will one day turn against them. Cast out and bitter, Leo roams the countryside, his reputation reduced to whispered rumors of a dangerous, untouchable savior. A chance whisper about Echidna’s attempts to rebuild her army draws Leo back to the source of the conflict. He proposes an unlikely alliance, only to be rebuffed by the Demon Queen herself. Undeterred, Leo negotiates with her four generals, who reluctantly allow him to operate in the shadows under the guise of a masked dark knight, Onyx. From the trenches of the demon stronghold, he begins to mend broken supply lines, resolve internal disputes, and subtly improve life for the denizens of the castle. All the while, his true motive remains: to uncover the hidden spark that set the war ablaze and to find a place where his overwhelming power can finally belong.

An overpowered hero joins the demon army he once fought, solving workplace problems in a lighthearted fantasy setting. The series blends action-comedy with themes of prejudice and belonging, keeping tone upbeat and violence non-graphic.
