Hiashi Hyuuga had three daughters.
Hanabi, his youngest, was a born fighter, she took to fighting like a duck to water. She was a true prodigy mastering the gentle fist style at a young age. She was strong and powerful and had a mastery of the Byakugan that some of the elder Hyuuga did not. And it was these skills in fighting that made Hiashi look over the fact that she was female and that she would not marry. She was too strong-willed to marry, to bend to any man, that was not her fathers, will. It did not matter that she was a good fighter if she did not carry the line on, but she would get away with being unmarried for longer than any other Hyuuga woman.
Then there was his second daughter, Hinata. Now she was the perfect wife, though she did not meet the Hyuuga standard. She was too timid. The perfect Hyuuga woman was strong like a tree to everyone she met. though to the clans males, be it father, brother, uncle or husband, she was to be like clay, easy to shape and bend. Hinata was like a flower though, a daisy that bent to the slightest of winds, that was not to say that she could not fight, she could. She would be married younger than most to strengthen the ties with other clans.
Lastly he had his eldest daughter, Sakura. She was the black, or rather, pink as some would say, sheep in the Hyuuga family. She was the child of his first wife, a woman named Shinami. She was a woman that he loved on sight, she was beautiful and kind. Though she was not a shinobi she was a medic, one of the best, so when she did the impossible and cured his father of a fatal disease he gave his blessing. They married right away, she was the first non Hyuuga to marry a main house member. She was killed a little after Sakura was born and the one responsible was never found. Sakura was the spitting image of her, from the weird pink hair to the bright green eyes. She did not have the Byakugan, another Hyuuga first, she did not have sight at all. Those bright green eyes were unseeing, the doctors said that the sight receivers in her brain just did not connect to her eyes. both the eyes and the brain were not things that were to be messed around with, not when she was not dying from it. So she remained Blind, it was a year after her mothers passing that Hiashi was forced to remarry, a Hyuuga this time. Hiashi secretly loved her more then his other two children though she was the furthest from a Hyuuga. She was too temperamental to be a wife, much like Hanabi, but she was unable to be a fighter because she was blind, because as the clan whispered where the main family could not overhear, 'she'll never be a ninja because she can't see.' But the truth was she saw more than they did.
