Chivalry Of A Failed Knight Vol. 12 (Light Novel)

Hagun Academy is a school that trains humans called “Blazers” who have supernatural abilities and are able to materialize weapons known as "Devices" which are created from a person’s soul. Every year, the academy selects representatives to participate in the Seven Star Sword Art Festival, a yearly tournament held by the seven Mage Knight Academies to find the strongest Apprentice Knight. Ikki Kurogane is a student of the academy who is a Blazer of the lowest rank and is known as the “Worst One.” His life changes when Stella Vermillion, the princess of a foreign country and an A-Rank Blazer, transfers into the academy. After accidentally witnessing her getting dressed, he is challenged by her to a duel in which the loser must obey the winner for life. Luckily for Ikki, he somehow wins the battle and the two become roommates, to Stella’s chagrin. How will their relationship change as they begin living and training together to qualify for the tournament? And will Ikki ever be able to shake off his reputation as the “Worst One”?
