Riley was a college student at Sun Tzu's Military Academy, the bestof the world. His life is cut short when his soul is ripped from his body and summoned into the body of a slave woman in another world. King Caligula summoned Riley as a Hero as the final act of desperation as his country is on the verge of collapse due to the heavy cost of fighting against monstrous invaders. As a hero, Riley has access to the Hero System, an omnipotent system that guides him in his quest to save others. Riley chooses to embrace his new identity, but at a great cost to himself. One that he may never recover from unless he can get help from elsewhere.
