The Royal Academy's Biggest Slacker Turns Out to Be an SSS-Rank Weapon

Who says a lazybones can't stir up an empire? When a military academy's perennial repeat student, who only wants to lie flat, is forced to accept a top-secret mission to overthrow an entire dynasty, should he keep playing dead on his leather sofa, or use the disguise skills he's perfected over countless years of slacking off to flip the board?

Guchi Fansaisi, the most notorious fixture in the history of the Royal Military Academy, had survived for countless years by exploiting loopholes in the school rules. But on the eve of graduation, royal spies dragged him into a dungeon. This master of disguise, who could infuriate his instructors into baldness, was forced to infiltrate the enemy nation's aristocratic circles, navigating between the lace skirts of a bloodthirsty duchess and a tyrant's bloodstained scepter. While the entire continent thought he was a dissolute tailor obsessed with red wine, he was using a sewing needle to pick apart the empire's darkest secrets.

As crimson moonlight stained the crystal goblet, would this lazy genius, who had turned a spy mission into a game of dress-up, discover that the regicide reflected in the glass was none other than his own harmless, smiling face?
