Hyuuga Hinata is the heir to the main family of the Hyuuga Clan. When she turned three years old her cousin Neji had a cursed seal placed on his forehead. After the seal was placed upon Neji, he grew to resent the main family for that and for what he saw was the unjustified killing of his father by the main family. Neji directed his hatred for the main family against his cousin Hinata. In the third round preliminary matches of the Chuunin Exam, Hinata and Neji were matched against each other. Utilizing the Hyuuga Clan's gentle fist style, Neji and Hinata began to trade blows. Neji's level of skill utilizing the Byakugan bloodline ability outmatched Hinata's and she became injured.

Thinking back to how she had seen Naruto refuse to give up, Hinata tried to become a stronger willed person and leave some of her timidness behind. Saying she wouldn't go back on her words and give up, Hinata began to trade blows with Neji again. Though Neji continued to injure Hinata, she refused to give up. This angered Neji to the point where he was going to strike a killing blow against her. Before he could do so, the Jounin masters watching the match jumped in to stop him. Hinata then collapsed due to the internal injuries she was suffering. Medical attendants took Hinata away but from that point on she was a changed person.

Before the start of the third test of the Chuunin Exam, Hinata had gone to the Genin survival training area. While there Naruto also showed up much to her surprise. Naruto told her he was experiencing some doubts about his abilities. Hinata took the opportunity to tell Naruto to not doubt himself. She let him know she was inspired by his determination and sees herself as more assertive and self-assured than she has been in the past. Hearing her reassuring words, Naruto felt better about his chances and told Hinata to come see his match where he would beat Neji. Then Naruto told Hinata that he thought Hinata was a dark and timid person, but he said he was wrong. Naruto then told her something that stunned and flattered her, he liked people like her. Blushing, Hinata could only stand in shocked surprise as the boy she liked expressed feelings for liking people of her type.

As the years passed, Hinata began to further push her limits and abilities and attained the rank of Chuunin. When Naruto finally returned to the village, she was embarrassed and stunned. Though she had grown in a lot of ways, her bashful crush on Naruto remained.

Hyuuga Neji carried an extreme hatred for the main family of the Hyuuga line. He grew up believing that the main family had killed his father as a demand of Lightning Country. The Lightning Country had demanded the body of the main family's Hiashi, what they got was the body of Hiashi's twin Hizashi. After Neji's loss to Naruto in the third test of the Chuunin Exam, Hiashi Hyuuga went to Neji to let him know the truth.

Seeing Neji's abilities Hiashi realized that Neji was ready to know what had really happened in the past. Neji was then told that his father himself made the choice to sacrifice his life. As a branch family member, Hizashi, like his son Neji, had a cursed seal placed upon his forehead which forced them to protect the main family or else they would face death. Hizashi saw the demand for his brother's body and asked that they use his body instead. He did it not because of love, but because by choosing death it would have been the first choice he could have freely made in protecting Neji, his family and the village. Taking his father words to heart to choose his own destiny and Naruto's similar words during their match, Neji changed his outlook on life and seeks to better himself with a brighter hope for the future.

Neji would join Naruto, Kiba, Chouji and Shikamaru in their mission to retrieve Sasuke from Sound. Neji would square off against Sound ninja Kidoumaru. The match proved difficult and bloody, with Neji having to sacrifice his body to finally take out his opponent. He pushed himself to live up to the ideal of what other ninja saw the Hyuuga as, the best of the best, and the greatest clan in Konoha. Luckily medical ninja soon found Neji and rushed him back to the village for care. With the expert treatment of Shizune and Tsunade, his body was repaired and his life saved.

In following years Neji would continue to push his limits and perfect his skill as a ninja. He would take the Chuunin Exam and pass, and then later advance to the rank of Jounin. When Team 7 needed help in rescuing Gaara from Akatsuki, he joined his fellow teammates Guy, TenTen and Lee in traveling to the River Country. There he helped fight Hoshigaki Kisame and later his own clone created through Akatsuki's protective sealing jutsu.

At some point in the past, Ao fought in battle against a ninja from the Hyuuga Clan. As a result of this battle, Ao was able to take the right Byakugan eye from the fallen ninja and have it implanted into his head. Though he was not Hyuuga, he could still make some use of the eye. It allowed him to see the internal chakra circulatory system of other ninja and help identify the chakra color unique to a particular ninja. While fighting the highly skilled Uchiha Shisui, he used this ability and made note of Shisui's chakra color.

Some time later, Ao used his Byakugan to also pierce the mind control affecting the Fourth Mizukage Yagura. He would use the eye again when he attended the Kage Summit. After being ill at ease for the strange turn the summit was taking, he activated his eye and realized that Sixth Hokage candidate Danzou had implanted the eye and arm of the deceased Shisui into his body. Knowing Shisui's ability to control the thoughts of others, he revealed Danzou's secret to the others attendees.
