Shion

is a priestess from the Land of Demons who is a main character in Naruto Shippūden the Movie. She was born with two gifts: to seal away demons, and to predict one's death. She had never been wrong until she met Naruto.

Plot overview
Shion had a very snobbish and bratty behavior towards Naruto, Sakura, Lee, and Neji in the beginning, such as demanding food and then throwing it all away for small problems. However, she gradually warmed up to the group. She particularly had feelings for Naruto. For a while, she can't seem to come face-to-face with him (much like Hinata). After he states that he'll protect her and that neither of them will die, she jumps back on his back and whispers to him "You promise?".

Shion, in the final scene after credits, was talking about how she will have to produce an heir (in case there is another demon). She asked Naruto to help her. Shion was basically asking Naruto to live with her and father a child, much to the shock of everyone else. Naruto, without considering what Shion's request really meant, happily accepted.
