Doomsday Bride

On her wedding day, the apocalypse arrives. The bride, Clara Sloan, is pushed to the zombies by her new husband and cousin, dying a tragic death only to be reborn. Returning to three days before the apocalypse, she chooses the overlooked "Shrinking System," hoarding supplies and building a secret fortress while coldly watching her past-life enemies kill each other with the "Enlargement System." This time, she won't be a sacrificial lamb; she'll be her own queen.
