OVER is the ruthless third member of "Four Heavenly Kings", the four elite members of Tsuru Tsurulina IV's Hair Hunting corp. (whom also includes Gunkan, Purupu and Halekulani) Unlike many Hair Hunters outside those seen much earlier in the series, OVER takes his job of ripping the hair out of the subjects of the Maruhage Empire extremely seriously and will treat all in his gaze as prey. This harshness for his job includes the treatment of his own teammates, as seen by his scalping of both Gunkan and Kitty Poo after their failures against Bo-bobo and the Hajike rebels. Although OVER can and will attack with little or no notice, he mostly controls his hair hunting activities from an ancient Japanese castle, where he controls a platoon of various ninja-like warriors including The Five Hidden Killers (dub: The Ultimate Five Assassins), who themselves are known for their stealth and abilities. He has noticeably long white hair and eyebrows with pointy ears and long chin. He wears a short black jacket that reveals his chest and white pants.
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.
