Chivalry of a Failed Knight

Magic Knights are warriors who wield weapons forged from their own souls, blending modern magic with combat. Ikki Kurogane attends an academy for these fighters, but he’s known as the "Failed Knight" or "Worst One" due to his lack of magical ability. His struggles take a sudden turn when Stella, a princess from another land and the school’s top-ranked student, challenges him to a duel with high stakes-the loser must swear lifelong obedience to the winner.
