The protagonist is reincarnated into the world of Brave War, a massive game he had poured tens of thousands of hours into, as the villainous noble Blado. What awaits him is a doomed ending in which he is certain to be executed by the hero's party—a group that is, in truth, utterly despicable. Drawing on his knowledge of the game from his previous life, Blado apprentices himself to the strongest hidden characters: the head maid, a legendary former female swordsman, and the housekeeper, a former court mage. After a year of grueling, blood-soaked training, he obtains the strongest power. Beginning with the entrance exam of the hero-training academy, Blado sets out to display an overwhelming one-man rampage, determined to overturn his destruction and crush the scumbag hero's party completely.
