A dark medical ninja who sought to revive the demon god, Moryo. By allowing his spirit to take shelter within his own body, he and his minions sought out to kill the priestess Shion while they recovered Moryo's physical body. In the end, Moryo killed him just as Shion was about to finish the sealing ritual.
Shion is a priestess from the Land of Demons. She was born with two gifts: to seal away demons, and to predict someone's death. She had never been wrong until she met Naruto. When she made her first appearance, Shion acted very selfishly toward everyone; her mindset being that she was more important than anyone else, therefore it was peoples' duty to give their life for her, shown in the first comment which she made, casually dismissing the fact that many people died for her by saying that their wish was to leave her unharmed. Toward the end of the movie, she develops feelings for Naruto, and even asks him to help father her child. Naruto, clueless as always, accepts without realizing the second meaning of her question.
Shizuku was a kunoichi who hailed from the Land of Demons. Shizuku is shown to be a graceful fighter with maneuvers of a rhythmic gymnast. Her primary battle tactics while under the influence of Yomi's dark chakra revolve around water-chakra. She can easily create large scale jutsu that can overwhelm the entire area or attack from huge distances. She can also move at great speed with little effort by gliding on a stream of water. If faced with a life-threatening attack, she can turn herself into water. Shizuku is the lone female member of Yomi's team on a quest to release M�ry�. During the first encounter with Naruto and his team, she demonstrated impressive fire-chakra skills that nearly killed Naruto. During the second battle, Shizuku performs the initial attack to separate Shion from her protectors by attacking them with an enormous Water Dragon. Neji is surprised to see that she has such tremendous mastery of water-chakra because he detected no such chakra in her during the previous fight.
One of Shion's most loyal bodyguards.
She sacrificed herself in order to seal away M�ry�. Miroku wanted Shion to live a normal life and prevented her from learning about her true powers, and as such prevented her guards from teaching Shion any ninjutsu. But to protect her daughter, she left Shion a special bell which allows Shion to foresee her own death in the future and be able to prevent it. However, to save Shion's life, another one must usually be sacrificed in her place.
