"Why am I the 'stupid youngest one' Diana Cartier!" In the novel 「The Ending Can't Be the Destruction of the World」, Diana is an evil woman who repeatedly commits evil deeds and is brainwashed by the villain, contributing greatly to the destruction of the world! If something could go wrong for the villainess, it will. But when something went wrong for me, I recalled my past life instead? As an ordinary college student in my past life, I made up my mind when I realized that I had been reincarnated as Diana Cartier, the villainess in the novel. "The world is going to end." "But I'm not going to let it happen."
