Actually, Hinata up and said that the one suffering the most of being cursed was Neji himself in chapter 81. She understood him very well despite being part of the main family because she also felt like disposable trash in some way. Empathy is a quality that politicians absolutely lack and why the world is so messed up. She deserved to be a leader cause she kind hearted, wise hardworking despite not being talented.
Naruto up and tells the genius to try to understand cause she is very similar to him.
I agree that naruto was the inspiration for her becoming stronger. However, Hinata basically reclaiming her title of heiress in springtime of youth and making her father eat his words was beyond satisfying. Boy, Neji training her made absolute sense ( he was feeling remorse for hurting her instead of abandoning like some one...). The talented born in wrong branch training the untalented of the main family. The Yin and Yan indeed... there really couldn't have been a better pair and naruto uniting them and bringing balance to the clan. My disappointment was that it only happened in a spinoff.
They are half siblings their fathers' are identical twins. They are not really cousins.
