A Chivalry of a Failed Knight
落第騎士の英雄譚 (original)
For Ikki Kurogane, graduating as a Magical Knight is nigh impossible. Among Blazers, he’s considered the worst; he can materialize his soul into a weapon, but his magical power is extremely low. To add insult to injury, an unfortunate encounter with the talented and beautiful Princess Stella Vermillion slashes his already slim odds and alters the course of his life forever.
