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, and 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, particularly Naruto with whom she has developed feelings for and for a while can't seem to come face-to-face with him (much like Hinata). After he states that he'll protect her and that neither will die she jumps back on his back and whispers to him "You promise?".

Shion, in the final after credits scene, whilst talking about how she will have to produce an heir (in case there is another demon) asks Naruto to help her, basically proposing to Naruto to live with her and father a child, much to the others' shock. Naruto, without considering what Shion's request really means, happily accepts.
