One day, I, a gamer, reincarnated as the villainous lord named Weiss of an RPG that I was obsessed with. In the game, he was just an underdog noble who gets defeated by the protagonist in the early game, but... this was a dream come true for me! Why? Because Weiss is my favorite character, and I've been running simulations on how to save him day and night. Once I used my knowledge of the game to destroy those doom flags, I somehow ended up governing well and earned the complete trust of my people. Not only that, but villainous heroines who were supposed to meet their tragic endings were saved and even began to adore me?! A fantasy story of a villainous noble using his knowledge to cheat fate, avoid his death, and save the villainous heroines along the way!
