Her Royal Highness Seems to Be Angry, Volume 3 (Light Novel)

Leticiel was born a princess in a time of war and revered as the greatest sorceress of her kingdom. After a devastating defeat during an invasion, she sacrifices her life to keep the enemy from stealing her magical powers — or so she believes.

But she awakens a thousand years in the future in the body of a pitiable young woman who is even scorned by her own family. There is plenty for Leticiel to be angry about, but at the top of the list stands a question: why is the magic of the future so weak?
