Naruto: Clash of Ninja/Characters/Iruka Umino
Iruka Umino is a Konohagakure ninja and instructor at the Ninja Academy, a school for prospective ninja. When Iruka was a child, his parents were killed by the nine-tailed demon fox, which was sealed into Naruto Uzumaki. He bears no ill will towards Naruto, instead being one of the few people at the start of the series to recognize Naruto as a person and not just a container for the fox. Naruto thinks of Iruka as a father-figure because of this, and Iruka in turn has great faith in Naruto's potential to be a great ninja.
