Extra's POV: My Obsessive Villainous Fiancee Is The Game's Final Boss Novel

When college student Ren Kuroda defeats the notoriously difficult RPG Eternal Souls: Last Judgment, a mysterious bonus stage transports him into the game as Terence Ross, an insignificant noble's son and mere background character. Aware that this world faces imminent destruction, Ren trains desperately to survive. His situation worsens when he's betrothed to Lilith Underwood, the future Third Great Calamity and the game's ultimate antagonist. Determined to prevent her catastrophic transformation, Ren attempts a dangerous gambit: fostering Lilith's emotional dependence on him to preserve her humanity. The strategy catastrophically misfires. Instead of remaining balanced, Lilith develops an all-consuming obsession with him that rivals the threat of her apocalyptic powers. Trapped between two equally lethal dangers, Ren must simultaneously suppress Lilith's destructive abilities while enduring her suffocating possessiveness. As the prophesied doom approaches, can a disposable extra alter destiny itself, or will he become another victim of the calamity he sought to stop?
