Her Royal Highness Seems to Be Angry, Volume 6 (Light Novel)

Leticiel was born a princess in a time of war and celebrated as the greatest magician of her land. After a devastating loss during an invasion by a neighboring country, she sacrificed her life to prevent the enemy from stealing her magical powers — or so she believed.

Until she wakes up and discovers she has been reborn a thousand years in the future. Even worse: the body she was transferred into belongs to a truly pitiable woman, despised even by her own family. There is much for Leticiel to be angry about, but at the very top of her list is one question: Why is magic in the future so lame?
