I'm Quitting Heroing

Leo Demonhart saved humanity from the cruel Demon King, but instead of being celebrated as a hero, he's met with fear and distrust.

However, the once-mighty force is now a shadow of its former self after its defeat at Leo's hands. To secure his place among them, Leo must now train the broken army back into a formidable fighting force.
