Ikki Kurogane may have come from a long line of Blazers, people with the ability to create weapons or devices manifested from their souls, but as far as the Hagun Academy is concerned, he's been a major disappointment in the magical powers department. He is so disappointing, in fact, that he's earned the unfortunate nickname of the "Worst One". However, things change for Ikki in the most surprising way when Princess Stella Vermillion, the most promising Rank-A Blazer to come along in many years, decides to transfer to Hagun. When she challenges him to a duel where the loser must obey the winner for the rest of their life, the last thing anyone expects is that the Worst One might prove to be a match for the Crimson Princess… and the unforeseen consequences will push the boundaries of society itself!
