The Crimson Witch and the Knight of Vows — The Reincarnate Protects the Girl in Their Second Life

Leon was a knight in his previous life. But he died without protecting the one person who mattered most. He woke up on a battlefield in a world of swords and magic — enslaved as a front-line soldier with nothing but his memories and his blade. He fought. He survived. He earned his freedom. Now he lives alone in a forest at the edge of nowhere, wanting nothing to do with anyone. In this world, the Nocturne Church rules with iron faith. Magic is called a sin. Those who wield it are hunted down.
