Thanks to her past-life memories, Pride has prevented the horrors wrought by the evil queen in the otome game—but now another kind of danger awaits the love interests. The continent is embroiled in an all-out war, and Pride will have to put on her princess face and join the effort if she wants to save the people she loves! The thing is, these events never happened in the original game... Without her last-boss cheats, does she have any hope of leading them to victory?
