The Ultimate NH Proof
You've probably seen this sketch somewhere before, done by Kishimoto.
Before Kishi had officially released the Naruto Manga, he drew sketches, including this one.
Notice that while Hinata is the clearly center of the drawing, we see Naruto in the background looking towards the Sun (Hyuuga = Towards the sun), and if it wasn't enough, the Sun and the pendant hanging on Hinata's necklace have the same spiral design Naruto has on his back. Perhaps Kishimoto had them bonded to each other from before starting the manga?
It also looks like there is a spiral in the sun as well. This all goes back to chapter 297's cover. Guided by a golden light, she now steps into the sun!
Thanks for listening/reading ^_^
