Beryl Gardernant is a humble sword master who runs a dojo in the Reveris Kingdom.
He had come to terms with the limits of his strength and was living a leisurely life in the countryside.
However, his life changes drastically when Alexia, one of his former students, suddenly visits him and tells him that she has recommended Beryl to be a special instructor within the nation’s Knight Order.
He is reunited with his former students who have become big-shots such as knight captains, top-ranking adventurers, and ace magicians, and he is kicked out of his family’s dojo.
Turbulent times were ahead of him.
