The Strongest Failed Aristocrat's Dark Demon Sword

Roy Revel is a frontier aristocrat from a lethargic small country. He is known as the "fallen aristocrat" at the school, but he has a secret.

"The patron god of the land of swords, Cloud the White Sword Saint.
The patron god of the land of magic, the great sage Eclipse the Black."

The strongest and most admired of the two great powers is in fact Roy, who plays the role of an incompetent! In order to protect his family, Roy, the strongest nobleman who manipulates the fight against the Empire from the shadows, is interested in the beautiful girls at the academy who aspire to become sword saints and sages.
