In a world where heroes and villains are shaped by powerful, game-like systems, Marcus Von Ricci—formerly the weak and bullied Marcus Leviathan—has embraced his dark, manipulative nature. Reincarnated with memories of his mafia past, Marcus quickly adapts to the academy's cutthroat environment, determined to rise through the ranks while maintaining the facade of a hero. With a Hero System guiding him, Marcus secretly steers himself down a selfish path, choosing power and chaos over noble ideals. He manipulates his classmates, allies, and even his lover, Sally Rosenthawn, who is unknowingly entangled in his schemes. Sally, once weak and overlooked, has become consumed by her own Villain System, drawing her deeper into darkness while remaining blindly devoted to Marcus. As the academy prepares students for a demon-infested world, Marcus and Sally's relationship becomes a twisted game of control and obsession. Marcus continues to manipulate events from the shadows, challenging top students and expanding his infamous reputation, while Sally struggles with the evil nature of her system. Unaware of her true role in Marcus's plans, she grows more powerful but also more unhinged, especially when left without his influence. The academy’s trials force them to grow stronger, with mutated monsters, rival students, and system-driven challenges testing their limits. As Marcus toys with the notion of heroism, his true goal remains dominance over those around him, while Sally’s desperation for his affection leads her further into the abyss. In this world of evolving systems and dangerous magic, Marcus and Sally must navigate their own ambitions and identities. As the line between hero and villain blurs, their bond strengthens, but so too does the darkness that threatens to consume them both. Will Marcus continue to play the hero, or will his true nature lead him and Sally down a path from which there is no return?
