Chapter 4 of NejiHina
Hizashi had been making a great deal of assumptions as of late. He'd assumed that the body which his niece had been leaning over was actually the body of his son. He'd assumed, upon discovering that the body had actually been his brothers', that Hiashi had finally overdosed on one of his frequent acid trips and was merely comatose. He'd assumed again, that if he killed Hiashi, they could be together in the afterlife giving Hizashi an endless number of opportunities for blackmail on his brother. Unfortunately, he'd also made an erroneous assumption with his latest move. He'd assumed that because he was a ghost, he would be able to see the ejected spirit of his son.
But he wasn't a ghost anymore. He was currently a spirit occupying the body of his niece. There are certain people who can see ghosts naturally. Hinata, her unawakened Main House magical girl genes notwithstanding, did not have this ability. Because Hizashi had taken control of her body, he shared her limitations. And he couldn't see the spirit of his son lingering in the room as he ran from it.
He was headed out of the house, in Hinata Hyuuga's body in search of Neji. Neji, who was disembodied and believed that Hizashi was Hinata, and was vowing to beat her so hard that she'd never raise a hand to him again! Especially when he couldn't defend it. And Hinata, whose father was currently in her cousin's body, was also disembodied, location unknown.
Someone, somewhere, was laughing uproariously. If it was anyone in particular, it was likely to be Sasuke Hyuuga.
----------------------
Sasuke Hyuuga was an interesting figure in the history of the Hyuugas. Though he was revered as the ancient progenitor and the Dark God of the Hyuuga clan, some had come to believe that he had never actually existed, and had actually been created by the Main House to perpetuate their beliefs in an organized manner. These people were mainly branch house Hyuugas, who had never experienced the reason why the Main House was so insistent that Sasuke was very much real and worthy of their worship.
That reason was called Herbert. Known to the Main House as 'Herbert the Angry,' Herbert acted as Sasuke's messenger, bringing disaster and despair to those Sasuke felt were being too 'happy' for the Hyuuga clan. The last time he'd appeared had been during the Hinata's disastrous kidnapping, and everyone had been miserable with the way that episode had ended. Except Herbert.
Herbert was angry. Herbert was always angry.
Thus resulted the 'misery' pyramid. Sasuke showered misery upon the Main House through Herbert, and the Main House threw misery upon the Branch House because Sasuke demanded that the Hyuuga clan be as miserable as possible. And he knew when anyone in the Hyuugas were happy. Nobody knew whether he simply sat around watching them from place hidden from the Byakugan, or whether he had some sort of power to see into their lives form afar, but when any Hyuuga was happy, Sasuke knew about it. And then he sent Herbert.
With a God like this, it was no wonder that the Hyuuga clan was screwed up.
----------------------
Neji was, unsurprisingly, one of those naive fellows who didn't believe in Sasuke. At a young age, his faith in anything but the Fate his father had talked about had been destroyed, and he refused to believe that Sasuke could overrule the object of his obsession. Ironic, because the source of his misery in life had mainly been Sasuke's malicious interference (and his own obsessive nature, but that's not relevant in this example).
More surprisingly, however, Hizashi was also someone who didn't believe in Sasuke. Though the term disbelieving is a bit inaccurate for his feelings about Sasuke's cult. It could be better described as desperately denying Sasuke's existence in a sort of 'if I can't see him, he can't see me' mentality. Hizashi, being the twin of a Main House member, had been privy to the truth of Herbert's existence. He had also had the pleasure of witnessing Herbert deliver his message of doom both before and after the Cloud debacle.
Hizashi believed in Fate because it was an impersonal arbiter of lives, or so he believed. Having been despised and disdained during his lifetime for being twins with a Main House member, he needed to believe in an ultimate force which, when it decided to screw someone over, did not do so personally. And then he met Herbert. Herbert hated Hizashi. Herbert hated each and every one of the Hyuugas with a passion made only hotter by the fact that he knew them intimately from wherever he came from. Herbert knew things about Hizashi that only his brother knew, and Herbert despised him all the more for it.
Hizashi's brain broke. From that point on, he'd made it a point to 'prove' that Sasuke didn't exist. He became morose, and embraced the legacy of the Branch family with every fiber of his being. He'd been something of an enigma to them before, having been extremely close to his Main House brother. But his sanity frayed, and he became obsessed with the idea of 'escaping' Sasuke by becoming a fully fledged Branch member, trying to sever all ties with the Main House, even going so far as to insist that his clone be cursed. By the time Herbert appeared again to announce Hiashi's impending death, Hizashi thought it would be a great idea to die. And the fact that it would destroy Sasuke's plans appealed to him much more than Hiashi's pleas (in bed) for him to live.
So Hizashi died. Sasuke didn't really care.
----------------------
The above tangent pertains to the current situation because Sasuke was, in fact, laughing at Hizashi. He was laughing at Hizashi, Hiashi, Neji, Hinata, and everyone even remotely involved in the entire affair. It was the best entertainment he'd gotten since that last time the Uchiha had tried to overthrow their founding house. And he'd decided that, in order to perpetuate the deliciously hilarious misunderstandings, just this once, he would have to take a direct hand in what was occurring. And the best way to do that was to remove what the gender confused ghost was searching for.
Sasuke sent a messenger to pick Neji's spirit up.
Guess who that messenger was.
