Byakugan Beauty {The One Neji Loved}

Part 1 - Black

*SPOILERS*
Anko Mitarashi, Ibiki Morino, and Genma Shiranui were on their way back from a mission. They had been body guards for the leader of a small village in danger. On their way back, Anko sensed something. "Ibiki, Genma?" Anko asked.
They nodded. "I sense it too." Ibiki said. "Me as well." Genma added. They soon found what they had sensed. Not an enemy, but a small injured girl. "What should we do?" Genma asked. "Should we kill her?" Ibiki said. They all froze as the girl opened her eyes. "Those eyes.." Anko said, "....the Byakugan!?"
...
The girl opened her eyes to see a woman with purple hair. "Wha-" "She's awake!" Anko said. "Who are you, kid?" Ibiki asked as calmly as possible. "All I remember is that...I'm 14 years old...I don't know my name." The girl whispered before blacking out again.
...
"Thank you for bringing her, Ibiki, Anko, and Genma." The Third Hokage said.
"I'll bring her to the Hyuuga clan." He added as they left.
...
"Does this girl belong to your clan?" The Third asked.
"No, we would've recognized her if she did. Is she an enemy?" Hiashi Hyuuga, the leader of the clan, stated.
"She isn't . She was found injured outside the village. Will you take care of her?"
"No-" Hiahsi started, but 15 year old Neji was watching, still not getting over the death of his father.
"Wait!" Neji shouted. Everyone looked at him in shock. A Branch House member interrupting a Main House member? As everyone continued to stare, Neji spoke up. "I-I'll take care of the girl!" He said.
"Why is that?" Hiashi asked.
"Because she's all alone isn't she? I'll train her to side with us and be able to use her Byakugan." He pleaded.
"No-" Hiashi started, but was interrupted by the Third Hokage,
"I think that would be the best idea." The Hokage smiled.
"Very well but we'll have to put the seal on her-" Hiashi started, only to be interrupted again
"She isn't part of our clan though! Don't involve her with our own matters." Neji said sternly.
Everyone looked like they could kill Neji in that moment, but Hiashi, convinced by the Third, stopped them.
"You must protect her. Treat her as if she is one of the Main branch. If she is killed and our secrets are revealed, you will be responsible." Hiashi stated bluntly.
"Yes sir." Neji agreed.
...
After that, Neji lead Blue to his small room. For he lived alone. "So, do you have a name?" He asked. "..." The girl was silent. "Don't be shy. I won't hurt you. Oh! Right, the Hokage said you didn't have a name, so how about..." He took in her features, noticing her raven - like hair, "....Black! How about that, Black?" He said. The girl nodded, smiling. Such a pretty smile he thought. "What's your name?" Black asked shyly. "Hyuuga Neji. I'm a year older than you." He replied. "Thank you for that." She muttered, smiling weakly.
...
It was the month before the final part of the Chūnin exams. Neji didn't practice, for he was confident. He might've , had he not met Black. He was utterly fascinated by the girl. He taught Black how to fight and use her Byakugan, along with many other things.
The two were inseparable.
