Shion

meaning "Sound of the tides", is a priestess from the Demon Country who is a main character in Naruto Shippūden the Movie.

Biography
Her mother sealed away a powerful demon causing her death, which returns in the 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.

Shion had a very snobbish and bratty behavior towards Naruto, Sakura, Lee and Neji in the beginning, with remarks like Sakura's back is making her uncomfortable while she was carrying her and that she (Sakura) should also make her body more womanly (causing Sakura to predictably blow her top in rage), rudely demanding food and then throwing it all away for minor problems. However, she gradually warmed up to the group, particularly Naruto who she developed a genuine affection for, mainly occurring after the two went on ahead to the demon's body, which was still sealed at the time and after arguing about who would or wouldn't die. Shion develops a crush on Naruto 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 whispering 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 asking Naruto to have sex with her and father an heir, much to the others' shock. Naruto, not exactly knowing what she ment, accepts happily.
