At a young age (7) Hyūga, Kyoko disagreed with the harsh actions done to the Branch House members of the Hyūga Clan. The boy thought it was unfair for the Main House members to treat their own cousins from the Branch House with such disrespect and dishonor having them endure such pain for years. Kyoko swore to himself that when he was older he would make sure everyone was treated equally regardless of what Branch of the Hyūga Clan they had been born into, that was a "child's dream" his elders explained. From that point on he wanted to get as far away as possible from the Main House. It was surprisingly in his favor the way he thought of it since he did not bear the seal which could suppress any Branch House member by restricting their own body movements.
As Kyoko grew older his hatred toward the head of the Main House Members grew stronger as they continued to abuse their power over the Branch House members, he couldn't take the sight of it anymore and decided to run away. (Age 20) One night in its deepest hour the young man dared to escape the Main House with no knowledge of where he was heading, with a bag of rations which would last up to a week he took off. Being trained and considered one of the best in the Main House because of his skill to suppress his own chakra making him invisible to sensors Kyoko was able to get deep into the forest. Making his way toward the minor countries North West from the Fire Country he came across a problem, his rations were depleted and his stamina was running low-not to mention he wasn't "home free" of the Fire Country. With the very little energy Kyoko had left and his Will Of Fire he was able to make it just outside the border of the Fire Country but with the lack of food and water the young Hyūga passed out.
The time of his death was to be or so he thought as his eye sight grew blurry. It was luck which had saved his life, a lone person from a large passing caravan of vendors who were just leaving the Earth Country spotted Kyoko's body laying on the side of a dirty road. Kyoko had gotten ill while in his travel but this one soul cured him, after weeks of traveling and catering the young Shinobi awoke to a surprise. In a carriage being pulled by two ox's miles away from both the Earth and Fire Country his eyes matched with a female who's skin was far darker than Kyoko's. The woman stared into his milky white eyes then said one life changing statement "Your eyes they're white.."
- "Yes, I am.."
Kyoko realized if he were to tell her that he came from the Fire Country also that he was a member of the Hyūga Clan he would be found, "I'm Blind."
he replied. The woman believed his false statement, but it wasn't so hard to believe since she had never seen a Hyūga up front. "My name is Minori and yours?"
From there on they lived together in a small village on the coast of the Thunder Country deeply in love with one another enough to bare a kid.
Growing up as a child Miyoko never knew about the Hyūga Clan and why Kyoko fled from the Main House, but her father spoke to her privately to help her understand why they were in hiding - Not to mention why he could not tell Minori that he and possibly his daughter possessed the Byakugan. It became taboo within the house hold.
Miyoko being curious she constantly questioned her father Kyoko about the rest of her family wondering what they were like to be around and why she and him had milky white eyes. During a hot summer day Kyoko took his daughter to a quiet lake and explained the prowess that laid within. He spent all summer teaching and guiding her until she was able to unlock her Byakugan.
The family moved off the coast and into an area where very few lived deep within the mountains. Becoming a young kunoichi Miyoko had learned to be a great ninja like her father, essentially learned to hide her identity and play blind too. Some people had taken noticed of the family though never bothered to say anything but one boy who constantly shouted that they were all Hyūga. No one believed him because they both acted accordingly.
