第 3 集: 風馬將神威託付給空太，京吾回憶起劍的起源，而那塔庫則偷走了它。
After treating Kamui's wounds, Fuuma leaves him in Sorata's care. Sorata tells Kamui how the Mount Kouya monks raised him to assist him in the fight to decide Earth's fate, but Kamui makes him escape when Sorata states that the monks also predicted he would come to Tokyo after losing his family. The next day, Kyougo recalls that the sacred sword was actually "born" from his wife, Saya Monou, who died during its creation. Kamui gets in contact with Kotori and Fuuma, telling the latter not to get close to him again. Just then, Kyougo is attacked by Nataku, a teenager who introduces himself as a Dragon of Earth. After Nataku steals the sacred sword, Fuuma and Kotori hear him and run to Kyougo. Kamui pursues Nataku, but fails to stop him as Sorata comments the monks also predicted that. (Source: Wikipedia)
