In a realm where destinies are intertwined with the threads of gods and demons, Xander Nightborn, once the feared Demon King, meets an unexpected fate. Struck down in a tragic incident, he finds himself standing before a divine being offering a twisted chance at redemption. Offered a system that promises power-ups in exchange for performing good deeds, Xander's existence becomes a battleground between his ingrained villainy and the divine force compelling him towards righteousness. Reluctantly, he embarks on sporadic acts of benevolence, driven more by curiosity than genuine change. Yet, his true nature refuses to be swayed, and he brazenly confronts the consequences, facing the system's punishments with defiance. While Xander treads the thin line between compliance and rebellion, a burning desire for vengeance against the manipulating deity festers within him.
