Spirit King : My Yandere Harem Novel

Ben, an avid seinen manga fan, finds himself mysteriously transported into a game that is actually an adult-oriented eroge. He awakens in the body of Daemon, a villainous character destined to be defeated and humiliated by the game's protagonist—a narcissistic, incestuous antagonist with a grim fate awaiting him. When all seems lost, a malfunctioning system suddenly activates, offering unexpected salvation. The Yandere Harem System binds itself to Ben, promising to help him build a harem of obsessive, devoted women willing to kill for love. His first target is Kara Geb Bentham, the game's secondary heroine and a frustrated lesbian whose desires have gone unsatisfied for months. The system's objective: convert her into a heterosexual yandere by proving that a man surpasses the satisfaction of her previous experiences. With this bizarre system at his side, Ben must navigate his dangerous new reality and pursue relationships with increasingly devoted women, defying his predetermined tragic ending.
