Kiba Inuzuka is a member of Konohagakure's Inuzuka clan and a member of Team Kurenai. Despite his headstrong, and at times egotistic attitude, Kiba is loyal to his comrades and will do anything to protect them with his trusted canine companion, Akamaru, by his side.
At a very young age, Akamaru was given to Kiba by his mother, Tsume, and the two became very close soon afterwards. Before entering the Academy, Kiba and Akamaru played together a great deal, resulting in Tsume getting 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 Chōji 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 Academy instructor. One day, Kiba fell asleep during class and, upon waking, saw Naruto attempting to use the Transformation Technique to turn into the Third Hokage for the first time, and failing twice. This caused Kiba to find Naruto incompetent, and he became among those who ridiculed him.
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, although he seems to agree that Tsume is rather frightening.
