A/N: Sadness!
"Why's it necessary to do something like that?" Naruto asked as tears fell from Kagome's eyes. "Why separate into a head family and a branch family? What does that weird mark mean?"
"This mark on my forehead isn't just a decoration. This Curse Mark is the absolute fear called death, so to speak. The secret sign that the head family members form easily destroys the cerebral nerves of those in the branch family. Of course, killing is easy. And the mark only goes away at the time of death. Sealing away the power of the Byakugan."
His eyes turned to Naruto with rage in them. "Hyuuga family is the clan that possesses the most distinctive Kekkei Genkai. There's no end to those who target the secret of that distinctive power. In other words, this Curse Mark keeps the branch family alive, only to protect the head family, and does not allow disobedience. It's an effective system created to defend for eternity the Kekkei Genkai called Byakugan."
He closed his eyes and Kagome fell to her knees. "Oi, Kagome-chan?" Kotetsu said, walking over to her. She shook as tears ran down her cheeks, covering her mouth as silent sobs tore themselves from her throat.
"And then, that incident occurred. My father was killed by the head family. One night, Hinata-sama was kidnapped. At that time, Hiashi-sama immediately rushed off and killed the abductor. Who do you think that person was...who was in the shadows, and also wearing a mask? The head ninja of the Land of Lightning, who had just completed the allied treaty. It was clear that he came, targeting the secret of the Byakugan from the beginning."
"However, the Land of Lightning exploited the killing of their own ninja due to a botched plan... and set an outrageous condition in violation of the treaty with Konoha. Naturally, things got continually worse, and there was almost a war between the Leaf and Lightning. However, the Leaf, who wanted to avoid war, made a deal with Lightning."
"A deal?" Naruto asked softly and Neji continued.
"The Lightning demand was the body of the Hyuuga head who possesses Byakugan, the Kekkei Genkai. In other words, the body of Hiashi-sama. Konoha accepted the condition, and a war was safely avoided. Thanks to my father, who was killed as a body double of Hiashi-sama. To protect the main family! Other than dying, there's no other way to escape this accursed Curse Mark. Even though they were twins with nearly equal power, their destinies were already set by who was born first and who was born later. And in this match, your destiny was decided at the point when I became your opponent."
Neji's chin lifted as he stood before everyone proudly, pain etched deeply into his eyes.
Kagome shook her head, her hand covering her mouth to prevent herself from calling out to him. Kotetsu placed a hand over her eyes and pulled her back into him.
"Get ahold of yourself, Kagome-chan." He said quietly, and she pulled away, furiously wiping the tears from her face as she stood. Proudly.
She couldn't look weak, as Neji's betrothed, she'd stand strong.
Without Gin's help.
