Spirit King : My Yandere Harem

In "Spirit King : My Yandere Harem," Ben, a dedicated fan of seinen manga, finds himself unexpectedly transmigrated into an eroge game. He awakens in the body of Daemon, a villainous character slated for humiliation and death at the hands of the world's protagonist, a cruel and incestuous individual. Just as Daemon's fate seems sealed, a peculiar Yandere Harem System activates, promising to help Ben construct a harem composed of devoted, albeit possessive, yandere women. The system's first objective is to transform the secondary heroine, Kara Geb Bentham, a lesbian frustrated by her current romantic endeavors, into a heterosexual yandere. Ben is tasked with proving to Kara that a man's affection surpasses the satisfaction of sex toys. The consequences of success, indicated by a mysterious reward, remain unknown. The mature and gore content warning highlights the potential intensity of this unusual situation.
