However, he was stopped and sealed away before he could do so by Miroku, the high priestess of the Land of Demons. His soul was sealed in the Land of Demons, and his body in the Land of Swamps.

Appearance
Mōryō is a gigantic serpentine creature with a very long and dark purple body, and multiple dragon-based heads, at least four are seen. His eyes are glowing red, and the tongues are blue. There is a lighter purple aura surrounding his body.

Plot Overview
Years after being sealed, the descendant of the clan that followed Mōryō, Yomi, came to free the demon's spirit when the stars begin to align, giving them a second chance to once again create the "Thousand Year Kingdom". Without his proper body, Mōryō will vanish moments after leaving the shrine, so Yomi offered his own body as a temporary avatar. From that point on, Mōryō inhabited Yomi's body, and gave orders to his four followers whilst controlling his stone army, who were headed toward the sealing shrine to retrieve Mōryō's body. When he arrived, he went inside and met with Shion, daughter of Miroku. He then confused her in order to distract her whilst he retrieved his demon body, while bursting out of Yomi and killing the man. Naruto Uzumaki then arrived, and they began to fight. Mōryō then tried to absorb Shion, but she was saved by Naruto. He was then killed by Super Chakra Rasengan.
