Tetsuya Izuburi (イズブリ・テツヤ, Izuburi Tetsuya) is a superior Mage of Iron Heart Guild, who is known to be deeply connected with its master, Ace Tempest. A kind and soft person, before the Balaur Vengeance Story events he was involved in different situations around the Dark Guilds within the Ishgar continent, receiving different aliases because of his actions and behavior. Commonly called as Tetsu (テツ, Tetsu), he is an inheritor of Novogaracan Family (ノヲガラカン組, Nowogaracan-Gumi), known to be a large mafia clan, which managed to hold a quarter of Dark Guilds influence over the whole continent, yet he discovered it only when he was fifteen, because he was kidnapped in the childhood by his family’s enemy, "Chain of Destruction" organization. Being involved in many crimes since childhood, Tetsuya began his story as a very furious Dark Mage; however, having a kind heart and light soul, he abandoned his dark past and what he had done, and decided to fulfil his own dream - cleansing the world from the darkness and sins, which he and others made.

Eventually, Tetsuya was found, raised and afterwards left by his foster father, Dragon Rioureus, a fearsome Demon Dragon of Hellish Flames (獄炎の鬼竜, Gokuen no Kiryū), when he was eleven years old, so the boy grew up with Hayashi Aririki. When a fated day, July 7, year X777, came, Rioureus went away, and after Tetsu and Hayashi faced his departure, both guys were searching him for three years, also practicing and honing their skills. At the age of fifteen, both Hayashi and Tetsuya went on separate ways too, yet they promised to each other to meet again in future. At the same time, Tetsuya was found by his real family and he began his own war against CoD organization, in order to get revenge for his deceased parents. As a new-found successor, he was claimed as the Dark Horse of Mafia World (マフィア世界の穴馬, Mafia Sekai no Anauma), which was later used by him to spread his influence over the others. Because of his actions within the Dark Guilds i.e. bringing the peace among many antagonistic magicians and stopping their activity, in Magic World he is best known as Armonia Dragoon (大空勇気の竜騎士(アルモニアドラグーン), Arumonia Doragūn lit. Dragon Knight of Heaven Courage).

Crimson Dragon Slayer Magic

Crimson Dragon Slayer Magic (紅の滅竜魔法, Kurenai no Metsuryū Mahō): Tetsuya is the user of Crimson Dragon Slayer Magic, being the Third Generation Dragon Slayers representer. Deriving his Magic from the two sources, the teachings of Rioureus and from the Dragon Lacrima implanted in his body, Tetsuya is able to transform the physiology of his body into that of the Crimson Dragon. The uniqueness behind the name and nature of this magic lies in the element he utilizes: the fire he is able to generate and manipulate to his every whim, is the merge between the Flame Dragon Slayer Magic and Purgatory Dragon Slayer Magic, granted to him from the teachings and the lacrima respectively. The crimson element, as Tetsuya often calls it, shows an extreme level of heat, one surpassing normal Fire Dragon Slayer Magic, being capable of burning through solid materials like metal, rocks, etc. Tetsuya is expert when it comes to his magic, as he is able to use it in many versatile ways. Besides that he can devour his respective element, with the exception of that which he has created, to replenish his energy reserves, can manipulate and generate it from any part of his body, and has the immunity to most types of flames, including explosions, Tetsu can increase his combat capacity immediately, incorporating his crimson element into his fighting style, greatly increasing the damage of his attacks. With his mastery, Tetsuya can change the element itself, for instance, make it solid to increase the blunt effect from his attacks or break through the thickest defenses, and with the phenomenon of the Flame of Emotion, it is possible for him to boost the heat of his element in terms of temperature, according to his emotional state.
