I Like Villains, so I Reincarnated as One: Since I Was Reborn as My Favorite Who Gets Killed by the Protagonist Early in the Game, I Used My Exclusive Game Knowledge to Crush All the Doom Flags and Somehow Ended up Becoming the King of Villains

From Kadokawa: One day, I, a dedicated gamer, suddenly find myself reincarnated as Weiss, a villainous lord from an RPG I’ve played extensively. He’s a disposable, minor-league noble destined to be defeated by the protagonist early in the game but for me, that’s a dream come true! You see, Weiss is my absolute favorite character and I’ve spent countless days and nights mentally simulating ways to save him. As I put my in-game knowledge to use, dismantling every "flag" that leads to his ruin, I somehow end up implementing a benevolent, well-regarded style of governance and, to my surprise, I’ve even won the trust of my own subjects.
