Inuzuka Kiba
Kiba is Hinata's teammate and pretty much the "Naruto" of Team 8. Kiba is about the same level of a shinobi as Naruto and is overconfident in his abilities and tends to spend more time goofing off. This young ninja's clan is famous for its abilities to speak and fight alongside animals. Kiba was given his pet dog Akamaru by his mother to train, but he normally gets a slap in the face by her for not doing so. Hinata views Kiba as sort of an older brother and spends time with him and her friend Shino more than anyone...at least when she is not stalking Naruto.
Aburame Shino
Shino is the higher graduating member of Team 8. He is an expert in using special insects to attack his opponents as is eveyone in the Aburame clan. He shows no real emotion except that of disgust and anger but he is very kind to Hinata nonetheless. Shino spends most of his time training and studying philosophy with his father. His good relationship with his father is something that Hinata tends to get jelouse of about him.
Hyuuga Hanabi
Hanabi is Hinata's little sister and the reason why Hinata's father looks down on her. Hanabi beat Hinata in a duel at the age of five. Hiashi found this to be disapointing and disgraceful to the Hyuuga clan. So instead of training Hinata, he lets Kurenai train her while he trains Hanabi.
