The story is about Serina Uesaka, a Japanese woman who is reincarnated as the evil villain in an otome game. Serina faces a tragic "Bad End" by being killed for a crime she did not commit. However, upon waking up again, she finds herself in a world that appears to be a sequel to the main game, taking place after the original "Bad End" - and worst of all, she seems to have been reincarnated once again as a villain!
