Kiba Inuzuka

At a very young age, Akamaru was given to Kiba by his mother, Tsume Inuzuka, and both of them became the best of friends. Before entering the Ninja Academy, Kiba and Akamaru played a lot together, causing Tsume to get angry because they weren't training enough. During Kiba's time at the academy, he often cut class with Akamaru, stating that he wasn't suited to sit still at a desk, or otherwise getting into trouble, along with Choji Akimichi, Shikamaru Nara, and Naruto Uzumaki. Together, these four would skip class and go to the practice hall (not to practice). They thought that it was fun to also test the patience of Iruka Umino, their Chūnin-sensei. At some time in the past, Kiba knew his father; but because of his mother's attitude, Tsume scared him away, leaving him just with her and his sister Hana Inuzuka. Despite this, Kiba stays in a close relationship with his sister and mother.Kiba is often short-tempered and impulsive (in stark contrast to his teammates Shino and Hinata), and can be prone to making mistakes when he becomes agitated in battle. The fact that he enjoys combat, as well as a habit of showing a joyful smile when facing a particularly strong opponent, indicates that he is willing to risk his life for a mission, and is rather bloodthirsty. He deeply cares for Akamaru, and is willing to do whatever is necessary to protect him. And, despite his rather gruff attitude, many of Kiba's actions reveal that he is very close to his older sister, Hana Inuzuka, and remains fiercely loyal to the Inuzuka clan.

Tenten

Tenten strongly believes that female ninja can be as strong as male ninja. Tenten's personal dream is to become as strong as Tsunade. She can be quite fierce sometimes, especially with Lee, violently shaking him whenever he is left unconscious. Tenten also has shown a strong distaste for weakness or being overly dependent on other people. Despite this, she is not above showing a softer side when it comes to her teammates. She holds great respect for her teammate Neji and often helps him train.Tenten has brown eyes and long brown hair gathered in Chinese buns. During Part I, Tenten wears a pink sleeveless blouse and dark green pants. Her appearance is a reference to the Chinese culture. In Part II, her outfit changes from a pink blouse to a white one and red pants instead of green. The shuriken holster and the bandage on her left leg is removed and wears black fingerless gloves; everything is still a reference to the Chinese culture. She holds a giant scroll on her back that she uses when fighting.

In the manga, during her first appearance her blouse was blue instead of pink which in later chapters, changed to her common Part I outfit. Her scrolls have also changed color from red and yellow to green and yellow.

Neji Hyuga

Neji was born with an unmarked forehead, but when his cousin Hinata, the main branch's heir, turned three years old, he was branded with the Hyuga Main Family's Juinjutsu by his uncle Hiashi. All branch members carry this curse mark, as it is a symbol that one lives only to serve the main branch. Neji's father Hizashi was well aware of Neji's natural talent, and he was frustrated that despite Neji's skill, Neji still carried the fate of a servant. Hizashi openly showed his anger; consequently, he was punished through Hiashi's activation of his curse seal. Around this time, the Leaf and Cloud Villages had signed an alliance treaty. However, that treaty only served as a ticket into Konoha and a lowering of Konoha's guard so the Head Cloud ninja could abduct Hinata and steal the secrets of the Byakugan. The attempt failed, though, as Hiashi intervened and killed the man in his tracks.

When word of the murder reached the Hidden Cloud Village, they demanded Hiashi's body as compensation (as his body would hold the Byakugan as well). The Hidden Leaf Village was prepared to comply to this request until Hizashi stepped in and offered to give himself up instead. Due to him being bound by the Hyuga Main Family's Juinjutsu when he dies, the Byakugan will be sealed away. Hizashi made this sacrifice willingly in order to protect his brother, family, and village. However, Neji came to believe that the main branch had forced him to do so. This misconception became the primary basis of his grudge against the main branch and of his concrete view on one's unalterable fate.

A year before the start of the series, Neji graduated at the top of his class, and was placed in Team Guy, with Might Guy as the Jōnin leader, and Rock Lee and Tenten as his teammates. After officially being promoted to Genin, Neji declined to reveal his dream, and laughed at Rock Lee for claiming that he could become a great ninja with just taijutsu. During their first year in Team Guy, Lee challenged Neji many times, but always lost. Guy decided to have his team wait a year before taking the Chunin Exams, in order to ensure that they were prepared. At some point before his first Chūnin Exam, his animosity towards the main branch became apparent to Guy, who made him promise not to let the issue influence his feelings during the Chūnin Exams.

Hinata Hyūga

Hinata is the eldest child of the Hyūga clan's leader, Hiashi Hyuga . As a child, Hinata was regularly seen as being rather shy. As the eldest child, it was her birthright to become the next heir to the Hyūga clan's main house. She was regularly put through grueling training by her father. One night, while still a child, she was kidnapped by ahead ninja from the land of lightning . Her father killed the head ninja to save her, which ultimately resulted in the death of Hinata's uncle, Hizashi Hyuga.

Despite the sacrifice that went into saving her, Hinata's father eventually deemed her a lost cause that was weaker than her sister, Hanabi Hyuga. When she was assigned to Kurenai Yuhi, he told her that he was unconcerned that she might die on a mission, saying that he had no use for a weak heir, and began concentrating on Hanabi. Hiashi then left Hinata in Kurenai's care.

Naruto Uzumaki

Naruto was born as the son of the Fourth Hokage,Minato Namikaze, and Kushina Uzumaki. Before his birth, they had decided to name him after the main character in Jiraiya's first book, hoping their son would be as great a ninja as the character was. This made Jiraiya Naruto's godfather. Soon after his birth, however, the Nine-tailed demon fox attacked Konoha. To save the village, Minato engaged the Nine-Tails in combat and sacrificed his life bysealing it within Naruto, believing his son would someday have use for it. Naruto was left to grow up knowing nothing of his parents, receiving only his mother's last name since the Third Hokage felt that it was best that nobody knew that he was related to the Fourth Hokage.Before Minato died, he asked that the villagers of Konoha view Naruto as a hero who had helped defeat the Nine-Tails. However, only a few of the villagers honored his request, while most instead resented him for containing the monster that had destroyed their home. In light of this, the Third Hokage decreed that nobody should ever speak of the Nine-Tails sealed within Naruto, hoping that their children would not resent him as they did. The children, however, followed their parents' lead, despite not knowing why. Iruka Umino would be one of the few exceptions. Despite losing his parents to the Nine-Tails, Iruka was always compassionate to Naruto's plight. For this, Naruto came to view Iruka as the father-figure he never had.
