I believe Hinata will meet Kaguya-Hime
I believe this because Hinata too lost consciousness like the two back in chapter 662. All three went down one after another. First Naruto, then sasuke, and finally Hinata.
And lets be honest, Hinata fainting over a trip is pretty unrealistic, unless of course, it was for the sake of plot, and by that I mean, meeting Kaguya.
There’s also the fact that Kaguya would be the perfect character to reveal the long awaited history of not only the hyuga but also the uzumaki clan, seeing her connection to the Byakugan and Uzumaki’s RDS. She could explain the creation of the cursed seal, jyuuken, the RDS, fuinjutsu, and other things related to the hyuga and uzumaki.
Hell, I wouldn’t even be surprised if it turned out that Kaguya was the one who developed jyuuken. I mean, she was a power hungry woman, so it would make sense for her to be the one who would exploit and take advantage of the Byakugan’s visual capabilities and chakra control enhancements.
Kishimoto also said some time ago that we would get development for the hyuga clan, and its clear from the looks of it, the revelation of Kaguya possesing Byakugan is merely the beginning of this development. Of course, it would only make logical sense for Hinata, the only relevant Hyuga character, to play a role in this development, especially with Neji no longer being around [unfortunately]. And when one considers her role as future clan leader, this further supports the idea.
Hell, this may very well be the reason lion fists has been delayed for all this time; its going to be used after Kaguya and Hinata’s meeting.
There are also some similarities between Hinata and Kaguya
•Byakugan
•Females
•Nobility
•Heiresses
•Leaders
•Stoic and Quite
• creepy (lol jk)
There is however, a difference in their ideologies in that, as Neji once said, Hinata wishes for harmony and peace by avoiding using power and kindness instead (much like Naruto and ashura) while Kaguya believes in using force and power to bring peace even if that means ridding herself of kindness (like indra and Madara). I think this will play a role in the sense that Kaguya will regret what happened to her and would want Hinata, her successor, to correct this.
Considering kishimoto’s trope of scary mothers with gentler sides (ex: Kushina), I wouldn’t put it past him to show a more motherly and loving side of Kaguya. This idea is supported even further when one considers, that, at this point, we only know Kaguya as an evil witch; and going by villains like Nagato, Neji, sasuke and Obito, its clear kishimoto isn’t the kind if author to paint his villains in a single color [of darkness], so I think we will see her side if the story. After all, she’s still mostly a mystery at this point
