Klein von Asgard was an ordinary lord that could be found everywhere. He ruled a peaceful territory without incident, but one day, an army was suddenly sent from the Marquis family, and the Viscount family of Asgard was destroyed. Klein lost his life as well, or so he thought. He woke up in his bed at home and noticed that he was had returned to three years before his destruction. Convinced that he would be destroyed in three years if nothing was done, Klein started a life-or-death survival operation in order to avoid the path of destruction. But he died. Time and time again, he died in trivial ways, and the territory was destroyed. He did not want to die. He also wanted to avoid the massacre of his subjects. With that in mind, he puts everything into redoing his life. Until the day of the happy ending.
