Chivalry of a Failed Knight - S01

In this world, a rare few can shape their souls into powerful weapons. Known as "Blazers," they train at the elite Hagun Academy to become Mage-Knights. Among them is Ikki Kurogane, the academy’s only F-ranked Blazer-considered a failure by everyone. But when Ikki accidentally sees Stella Vermillion, an A-ranked Blazer and a princess, naked, she challenges him to a duel with high stakes: the loser becomes the winner’s slave. Surely Stella can’t lose to the weakest student, can she? While fighting to prove his strength in a world that dismisses him, Ikki grows stronger, makes allies, and learns valuable lessons along the way.
