Altina the Sword Princess

Regis Ulrich is an incapable soldier; bad at both sword and archery, who passes the time by only reading books. While transferring to a remote region post, he meets a girl who turns out be the red hair and crimson eyed princess Altina, the wielder of the Supreme Ruler's Sword. Despite being only fourteen years old, she was appointed to become the commander of the army in the remote region simply because she was the illegitimate child of the Emperor. However, she continues to hold onto her dreams of becoming Empress despite the circumstances that surrounds her. To achieve this goal, she asks Regis to become her tactician and stand alongside her against the obstacles they are sure to face.
