Shion

is a priestess from the Land of Demons, who was a main character in Naruto Shippūden the Movie. 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.

Personality
When she made her first appearance, Shion acted very selfishly towards everyone, her mindset being that she was more important than anyone else, therefore it was peoples' duty to give their life for her. This was shown in the first comment she made, casually dismissing the fact that many people died for her by saying that their wish was to leave her unharmed. She also acted rather snobbishly, complaining about the smallest of things, such as (while riding on her back) how uncomfortable Sakura's back is to ride on, as well as the small inconveniences in the food.

Naruto uncovers the reasons behind her attitude, since he himself went through the loneliness and pain of being an outcast from society, just as she did, due to people fearing an appearance in one of her predictions, although, clearly, both parties dealt with this in different manners. She also felt sad when her loyal servant Taruho died, and tried to mask her emotions with indifference, but failed. After her adventure with Naruto, she changed for the better, becoming more open and kind, and even developing romantic feelings for him.

Plot overview
Shion first acted in a very snobbish and bratty manner towards Naruto, Sakura, Lee, and Neji, such as demanding food and then throwing it all away for small issues. However, she gradually warmed to the group. Especially Naruto whom she developed romantic feelings for. For a while, she couldn't seem to come face-to-face with him (much like Hinata who is also in love with Naruto). After he stated that he would protect her, and that neither of them would die, she jumped back onto his back and whispered to him, "You promise?" She was even willing to sacrifice herself to save him from his predicted death. However she was stopped by Naruto and the two of them formed the Super Chakra Rasengan, and destroyed Mōryō.

Shion, in the final scene after the credits, told Naruto that she would have to produce an heir in case there was another demon. She asked Naruto to help her. Shion was basically asking Naruto to live with her and be the father of their child, much to the shock of everyone else. Naruto, unaware what Shion's request really meant, happily accepted.
