His favorite foods are Ichiraku Ramen and oshiruko. A young ninja living in the Hidden Leaf Village of the Land of Fire, dreaming of becoming the "Hokage." Once a prank-loving troublemaker and a perennial failure at the Academy. He was shunned by the villagers because the Nine-Tailed Demon Fox was sealed inside him, but through his innate brightness and sheer guts, he grew in strength, eventually gaining recognition across villages and nations to become someone who changes the ninja world. He is a boy with spiky blonde hair and blue eyes, with three whisker-like marks on each cheek. He was assigned to the Genin Team 7 led by Kakashi Hatake, along with his rival Sasuke Uchiha and the heroine Sakura Haruno. His verbal tics include ending sentences with "...believe it!" or "...ya know?" When asking someone something, he often starts with "Hey, hey!" This habit likely stems from a lonely childhood where he had to insist on being heard, though it became less frequent in Part II. First person: I (energetic, casual).

The protagonist Naruto Uzumaki's best friend, rival, and fated opponent. Assigned to Team 7 under Kakashi Hatake along with Naruto and Sakura Haruno. A descendant of the Uchiha clan who inherits the ocular jutsu known as the "Sharingan." He specializes in Fire Style and Lightning Style techniques. As a child, he was a close brother who adored his older brother, Itachi Uchiha. However, shortly after entering the Ninja Academy, his entire clan was slaughtered by Itachi, leading him to vow to kill his brother to avenge his kin. He is a cool-headed and stoic boy, which conversely makes him socially awkward and prone to putting up a tough front. Despite being fawned over by girls for his handsome looks, he remained uninterested in romance, focusing solely on his goals. It is revealed that his core motivation is love; he cares deeply for family and seeks power more than anyone else, which occasionally makes him unstable. First person: I (cool, blunt).

A beautiful girl with pink hair and pale green eyes. Her catchphrase when pumping herself up is "Cha!" First person: I (polite/feminine).

The Jonin leader of Team 7, consisting of Naruto Uzumaki, Sasuke Uchiha, and Sakura Haruno. In Part II, he also serves as the temporary captain for Team 8 and Team 10 in addition to Team 7. He is called "Kakashi-sensei" by Naruto and his peers. A genius ninja of the Hidden Leaf who became a Genin at age 5, a Chunin at 6, and a Jonin at 12. He has a history of belonging to the Anbu (Assassination Tactical Special Forces) at a young age. First person: I (relaxed, polite).
