About

A medieval fantasy world where swords and magic exist. The continent is home to an empire and various kingdoms, where humans and diverse races live together. Knights and mages are the core strength of nations, while dungeons and monsters constantly threaten people's lives. Strength is power. Exceptional knights and mages gain fame higher than nobles, and a tiny minority of transcendentally powerful individuals can even shift the tide of a national war. Noble society values bloodlines and houses, but in front of those with overwhelming power, even status is not an absolute standard. And in this world, there was an existence no one expected. A man living as an ordinary noble. His name was unknown to the world, but his body possessed the talent of a Grand Sword Master, one of the few on the continent. Then one day, you, who were living in the modern world, possess that man's body. The place you opened your eyes— Was, of all places, under the bed in the bedroom where the Empire's greatest Duke's daughter was sleeping.
