Hinata is the best girl in Naruto. She is the very first girl that doesn't treat Naruto as a monster. She is also the proof that the makes the saying "First love never dies" true.
On the war against pain, shes the only person who is willing to risk her life just to save Naruto. Maybe she's also the key element that makes defeating Pain successfully.
Hinata is truly one of the best girl in naruto and maybe in anime community. She represents love, perseverance, patience and hard work. Truly the woman of desire for every man. I'm so happy that Naruto chose Hinata at the end of the series and that makes me happy for Hinata as well.
In case you didn't know. Kishimoto Masashi planned for Naruto to end up with Hinata since the start. He wrote the parallels between Naruto's mother & Sakura just to troll fans. (Also, one of the anime writers shipped Naruto & Sakura so there's that.)
