Iruka Umino

Iruka Umino is an instructor at the Ninja Academy. He is characterized by the distinctive scar across his face that he has had since childhood.
His parents were killed by the Nine-Tailed
Demon Fox when he was younger, though he
holds no hostility towards its container, Naruto
Uzumaki. In fact, Iruka is one of the few people
at the start of the series who values Naruto as a
person, being able to relate with Naruto's methods
of trying to gain attention. Because he, like Naruto,
was forced to grow up without parents, and was
socially isolated as a result, he can relate to Naruto in this regard as well and has assumed the role as Naruto's father-figure. Once Naruto becomes a ninja Iruka starts to underestimate Naruto, and as such become overprotective of him, though he in time discovers that Naruto has all the makings to become a great ninja.
