Equipment
 (黃龍, Ōryū): The Sacred Beast of the Nakiri Clan that has been handed down for generations to the strongest mystic of the clan who is personally chosen by the Sacred Beast itself, along with its name. Talisman: Ouryuu can use spell talismans powerful enough to dispel Nanao's twisted monsters into nothingness.
 * Dragon Veins: As the Sacred Beast that represents earth, the Yellow Dragon grants Ouryuu the ability to tap into the "veins" of ki that flow throughout the land letting him utilize the earth-based ki to strengthen his own physical abilities to significant degrees. As such, if Ouryuu fights in locations where the earth is rich, he will have a greater supply of earth-based ki to draw from, therefore making him stronger. He is also capable of shooting balls of dragon aura at his opponents. He can also control the terrain of earth and use this to his advantage to bring opponents closer to him or catch them off guard.
 * Touki (闘気, Fighting Spirit): Ouryuu covers himself in an aura of ki, drastically increasing his strength, defense, and speed. By using this in conjunction with his Dragon's Pulse ability, he can further enhance his Touki.
 * Dragon Man (龍鬼人, Ryūkijin): A technique of Ouryuu's that allows him to transform into a golden humanoid dragon. This technique greatly enhances his physical abilities, allows him to hurl giant spheres of Touki at his opponents and to fire numerous bullets of Touki mixed with dragon aura.
 * Dragon's Fang (龍牙, Ryūkiba): A technique of Ouryuu's that allows him to conjure a sword-like fang made of ki.
