Naruto was born on October 10, but not much is known beyond that. His parentage remains a mystery, as do any other family ties he may have had. As a newborn infant, the nine-tailed demon fox, which had attacked the village of Konoha, was sealed within Naruto's body by the Fourth Hokage of Konoha.Despite the Fourth Hokage's wish that Naruto be seen as a hero who contained the demon, the villagers of Konoha harbored a fierce hatred for the young child, since he bore the spirit of the demon who decimated their once peaceful village. Naruto wasn't even aware of the presence of the demonic entity inside him until he was twelve years old, leaving him confused for most of his childhood about why the villagers of Konoha hated him so.Fortunately, Naruto was befriended by his compassionate ninja instructor, a Chunin named Iruka Umino. Though Iruka's own parents perished at the hands of the demon fox, Iruka didn't blame Naruto for their deaths. Instead, Iruka accepted Naruto and empathized with the boy's desire to be accepted, since he too once had the same desire. He may have been the first person to believe in Naruto, and has made a lasting impact on Naruto himself. It is through Iruka's presence as Naruto's only family figure that Naruto learns to overcome his sadness.
