The Yandere Demon Lords & Me

Rein Aster, an unassuming herbalist farmer from a remote village, finds himself an unlikely key player in a world of prophecy and divine warfare. His quiet existence is shattered when, by fate, he rescues one of the seven Demon Lords during a devastating war. Instead of destruction, the Demon Lord develops an obsessive, violent, and eternal love for him. This fixation soon spreads, as the other Demon Lords also fall for Rein. Each Demon Lord attempts to claim Rein as their own—lover, pet, priest, husband, or god—constructing elaborate prisons like dungeons and illusion palaces. Yet, Rein consistently evades their clutches, never outright rejecting them but refusing to yield. He's realized that the gods are more tyrannical than demons and heroes are cruel figures. As the world crumbles, Rein becomes the sole figure these powerful beings heed. He conceives a plan: to leverage the Demon Lords' devotion to seize control of the world, pitting them against heroes and gods alike, making them fight and kill for him. Ultimately, he aims to tame them not as a ruler or savior, but as the one they'd destroy the world for. This novel features intensely dark yanderes and a pervasive somber atmosphere.
