The King of Heroes reincarnates to polish his skill to the limit and becomes the strongest knight in training in the world

King Inglis, who lived for his country and people, strongly hopes that in his next life, “I want to live freely and pursue the path of the warrior.” The wish is heard by the goddess who reincarnates the king into the far future but in the form of a cute girl!　Moreover, it is declared at the age of 6 that she is incapable of being a knight even though she is the daughter of a Master Knight.
