Chivalry of a Failed Knight - S01

In this world, a rare few can shape their souls into powerful weapons. These individuals, known as "Blazers," train at the elite Hagun Academy to become Mage-Knights. Among them is Ikki Kurogane, the only F-ranked Blazer-considered the academy’s weakest. But when Ikki accidentally sees Stella Vermillion, an A-ranked Blazer and a princess, naked, she challenges him to a duel with a brutal condition: the loser becomes the winner’s slave. Surely Stella can’t lose, or can she? While fighting to prove his strength in a world that dismisses him, Ikki finds allies, grows wiser, and gains valuable experience.
