Rise of The Fallen Hero (Old)

Once hailed as the world's hero, the protagonist sacrificed everything for the sake of humanity—family, friendships, and even love. His relentless training and countless adventures were undertaken without regret, driven solely by the belief that humanity's survival was paramount. But after vanquishing the once-invisible Demon King, betrayal struck. His own allies, driven by jealousy and fear, plunged a blade into their back, revealing the depths of humanity's dread. As their soul dispersed into the void, a desperate roar reached the ears of Satan himself. A pact was struck, and he was granted an opportunity for vengeance. Reborn at the beginning of their hero's journey, his heart harbored no hope for humanity, no reverence for gods. Only the power of darkness remained, coupled with an unquenchable thirst for retribution. Guided by the malevolent Dark System, the fallen hero embarks on a relentless quest for vengeance, and his path marked by shadows and treachery.
