Iruka Umino (うみの イルカ, Umino Iruka) is a Konohagakure chunin and instructor at the Ninja Academy, a school for prospective ninja. Masashi Kishimoto's initial design of Iruka featured "evil" eyes and sharper cheekbones, but this was abandoned in favor of a more relaxed appearance.When Iruka was a child, his parents were killed by Kurama, the Nine-Tailed fox which was later sealed into Naruto Uzumaki. At the start of the series, he often found it awkward around Naruto, but after Naruto was targeted for death by Iruka's friend Mizuki, Iruka became the first person who acknowledged Naruto, and they ultimately saved each other against Mizuki. The Third Hokage chose Iruka as Naruto's sensei on purpose because of their similar backgrounds.Naruto thinks of Iruka as a father-figure because of the fight against Mizuki and Iruka, in turn, has immense faith in Naruto's potential to be a great ninja. During the Fourth Great Ninja War, Iruka is dispatched by the Allied Shinobi Forces to stop Naruto from leaving the island where he and Killer Bee are being kept safe. However, upon finding out that he was deceived, Naruto abandons Iruka, but Iruka slips Naruto a good luck note into his headband, restoring their mutual faith. In the final episode of Naruto: Shippuden, Naruto asks Iruka to stand in as his father for his wedding. In Boruto: Naruto Next Generations Iruka has become the headmaster of the Leaf Village Ninja Academy. In the Japanese anime, his voice actor is Toshihiko Seki, and his English voice actor is Quinton Flynn in the Naruto and Naruto Shippuden series and Kyle McCarley at the end of the Naruto Shippuden series and Boruto: Naruto Next Generations.

In the anime, it was revealed that Iruka became a teacher because he wanted to pass on the Will of Fire to the next generation in this manner, inspired by the Third Hokage's wisdom. When Naruto became his student, he found it awkward to deal with the person containing the very monster responsible for his parents' death. He tried to ask the Third Hokage if he could not teach Naruto, though he was eventually disabused by the notion by Kakashi Hatake. Later, Naruto went into the woods to steal items from corpses. Iruka chased him down and protected him from Takigakure spies who were attacking Naruto, eventually backed up by Kakashi. After saving Naruto and bringing back the document attached to the artefact the latter retrieved, he reprimanded Naruto for such a reckless behaviour. This would surprise Naruto as this was the first time anyone in the village showed they actually cared for his well-being. He also thanked the Third for assigning Naruto to him. He thus resolved to be straight forward and deal with Naruto strictly in class from then on, in order to train him to become a fine shinobi. As a result, Iruka became the main reason Naruto did not become a sociopath like Gaara did.

This was a very simple custom I made

I took the head from an Iruka keychain and put it on the body of the Anime Heroes Kakashi
