Sorata was first introduced as a Dragon of Heaven fighting against Yuuto Kigai, a Dragon of Earth, inside of a kekkai he created himself, a perfect cube. Later on, during the fight, an intruder enters, Fuuma that shouldn't even have happened and should be impossible. Right after, Sorata dispells his kekkai and approach Kamui. At first, Kamui doesn't believe him that he is a Buddhist monk and told Kamui that he is one of the Dragons of Heaven, involved with the upcoming battle and the reason why Kamui returned, because of Kamui's mother's death.
