BackgroundIruka's parents were killed in the Kyuubi's attack on Konoha twelve years before the beginning of the series. Initially, a young Iruka was present on the battlefield, and wanted to stay in order to protect his mother. His father declared that it was the parents' duty to keep their child safe from harm. He was forcibly removed from the battlefield by an unknown shinobi while he called out for his parent to no avail. At the funeral of the victims that were kill that night, Iruka was seen mourning his parents death.
With his family gone, Iruka had no one to give him attention. Iruka therefor became a prankster much like Naruto would later become, trying to gain attention to stave off his loneliness. He would spend his time at the monument where his parents' names were engraved, and in his darkest moments would be cheered up by Sarutobi Hiruzen. Mizuki was a childhood friend of Iruka's after the Nine-Tails Attack, and usually made him feel better. In the anime, it was noted that due to other people giving Iruka more attention than they do to Mizuki, Mizuki's kindness to Iruka was revealed to be an act just to gain the Hiruzen's approval, all the while making Iruka more miserable. He then took a test with Mizuki to see if he got the job to be a teacher. Iruka finished the test and got the job, but didn't notice that Mizuki was angry with him.
In the anime, it was revealed that Iruka loves to eat ramen at Ramen Ichiraku and enjoys when he asks Teuchi for seconds. He 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 Uzumaki 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 of Hatake Kakashi. Iruka then saw how the villagers angrily gave Naruto the cold shoulder when he was in the park.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 he was backed up by Kakashi. After saving Naruto, and bringing back the document attached to the artefact the latter retrieved, he thanked the Third Hokage for assigning Naruto to him. Iruka told the Third Hokage that he will pass down the Will of Fire to Naruto and the next generation. While talking to Naruto outside of the Ninja Academy, who asked him where was the kunai that he found. Iruka who didn't answer Naruto's question at all, instead he yelled at Naruto for the first time. Iruka even scolded Naruto for almost getting kill at the back hills, when he asked Naruto why was he being so quiet. Naruto told him that this was the first time that he yelled at him, which surprised him.
After hearing Naruto's response; Iruka 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. Thus he was the first person to teach Naruto about the Will of Fire along with telling the boy about the Fourth Hokage being a legendary hero. It was this story that had led Naruto to excitedly tell Iruka that his dream is to become the Hokage. Iruka then happily place a mark on the tree telling Naruto that he will probably become Hokage when he reached the mark. Then he smiled happily when Naruto tell him that he will work real hard to become the Hokage. As a result, Iruka became the main reason Naruto did not become a sociopath like Gaara did.
Eventually, he would often watch Naruto be defeated in a sparing match with Uchiha Sasuke, and would fell bad for him. He would also lecture on how bad his transformation technique is, and would catch Naruto cut class. However he would see Naruto do this with Kiba, Shikamaru and Choji. They thought that it was fun to test Iruka's patience, which annoyed him to no end. Therefore Naruto and his friends would even hide in the training hall to get away from Iruka's class lectures. However Iruka would always find them and bring all four of them back to class. As Shikamaru pays no attention to class, along with Choji sleeping. Iruka chastises him for sleeping. While Choji throws a book at Shikamaru. This makes Naruto complain about the noise, as he is trying to sleep.
Iruka scolds Naruto as well by saying he can't sleep in class. He sends the three of them to the hallway. Therefore Choji offers them snacks, and when Iruka comes see them, they're standing asleep. So Iruka scares them awake, and happily laughs as they wake up. Later, as Naruto stands up to bullies bothering Hinata. Shikamaru and Choji begin fighting, but Naruto interrupts it, and the three end up laughing. Iruka then smiles upon seeing the three get along. He then speaks to Hinata afterwards. After class, the three see Iruka flirting with some women. But he gets a nose bleed by seeing Naruto's Sexy Technique.
When Naruto reaches age 10 - 11, Iruka would annoy Naruto's classmates by having them review whatever technique Naruto missed out while pulling pranks. Eventually before the start of the series, Iruka would always catch Naruto pulling pranks on the Hokage Monument and would yell at him to go back to class. It was during these two years that Iruka saw Naruto fail the Ninja Academy graduation exam twice.
PersonalityIruka is described as being both big hearted, and soft hearted. This is most often seen through his teaching methods, often giving a watchful eye over his students as they progress. This however, does not mean that he is a pushover, as he can be stern when the situation calls for it most often seen when he shouts at his students in order to get them to obey him. Despite the tragedy of losing his parents at a young age, Iruka remained a determined and strong-willed individual with a kind disposition. This is seen from his lack of hostility towards Uzumaki Naruto who was often the victim of misplaced anger at the Nine Tailed Demon Fox who was sealed within Naruto. Because of this, Iruka came to be the only person Naruto respected in his youth as well as the only person who could control Naruto's behavior to some degree. Naruto ignored all chunin and jonin who reprimanded him for painting all over the Hokage's faces and only showed fear when Iruka showed up. Ironically when Iruka scolds him for almost getting kill in the back hill, this made Naruto realize for the first time, that Iruka actually cared for his well being.
As a child growing up without his parents, Iruka turned to performing antics in the Ninja Academy in order to gain recognition from others who would otherwise pass him over or look at him with pity for being an orphan. This allowed him to also see some of these signs, and understand what they meant when displayed by Naruto. Due to Iruka's more nurturing, protective and compassionate nature, Naruto views him as a surrogate father and mentor whereas Iruka in turn, views Naruto as a younger brother. The two enjoy their favorite ramen dish at Ramen Ichiraku whenever Naruto returns from a mission, where Iruka gets an opportunity to see how Naruto is developing as a ninja. Iruka's refusal to allow Naruto to graduate at first was not out of spite, but merely out of caring strictness and a desire for Naruto to work harder and reach his own potential.
He also has a great sense of duty, honor and selflessness as seen when he protected Naruto from Mizuki's attack, suffering a shuriken wound in his back in order to protect him. He greatly admires the Third Hokage, who was there to help him during his troubled period as a child, and believes strongly in the Will of Fire of the village. As a result, he regards the children of the village as the backbone of Konoha — even being willing to sacrifice his own life to ensure their safety. Iruka, who was neglected as a child due to his parents absence, is quite similar to Naruto. Although he has occasional moments to bash out at him, Iruka is aware of Naruto's suffering and loneliness, in which he is always trying to be there for him as much as possible. In addition, Iruka is greatly supportive of Naruto's dream to become the Hokage, and is very grateful for him accomplishing his dream.
Iruka is a man of average height, and build. He has black hair (brown in the anime) that he keeps in a ponytail, dark eyes and a scar that runs across the bridge of his nose which he has had since his youth. He wears the standard Konoha shinobi outfit complete with forehead protector, sandals, and flak jacket. His sleeves are also rolled up about ¼ way. As a child he wore a simple outfit along with mesh-armor underneath it.
Two years after the Fourth Shinobi War, Iruka's overall appearance stayed the same. The only noticeable difference is he wears a Uzumaki clan logo armband on his left arm with the new standard flak jacket, and high-top sandals. Several years afterwards, Iruka has aged further, with slight creases around his mouth. He also abandons his forehead protector and shinobi attire, and instead dons a grey zipped shirt.
As a head instructor of the Ninja Academy, Iruka is clearly proficient in all forms of basic ninja skills. He has some ability with Barrier Ninjutsu, as he is seen creating a barrier in an attempt to restrain Naruto. Iruka is also very perceptive as he can assess situations carefully, and quickly while under threat. In terms of nature transformations, he's capable of using Fire Release and Water Release. He is also capable of utilizing Yin Release.
In the anime, Iruka's skills were expanded upon; it was shown that he had some knowledge of genjutsu, as demonstrated when he posed as an enemy Amegakure ninja to test Sakura, and he also saw through the genjutsu cast by Mizuki. During the Mizuki Strikes Back Arc, Iruka showed some skill in taijutsu as well, by keeping on equal footing with the now-improved Mizuki in his attacks. Iruka was also shown using Sealed Bomb Square Release, which consists of setting an array of exploding tags and, once the target has entered the area, setting the tags to detonate if the target moves.
Also, in the anime, Iruka displayed what seems to be an echolocation ability where he can get a sonar image of his surrounding area, perhaps playing on the meaning of his name, "dolphin".
Naruto (Part I)
When Uzumaki Naruto managed to evade other ninja after desecrating the Hokage Monument with graffiti, Iruka captures his student and berates him for not focusing on the upcoming graduating exams. While Naruto was supposed to transform into Iruka, he instead did his Sexy Technique, with Iruka suffering a massive nosebleed before giving Naruto a reprimanding. Iruka then punished Naruto by having him clean the Hokage Monument, but then invited him to Ramen Ichiraku, where he learned once again of Naruto's dream to be Hokage. When Naruto asks Iruka if he can wear his forehead protector, Iruka told him that he would have to pass the test. He then realized that this was the true reason why Naruto took off his goggles while they were eating.The next day, when Naruto failed to conjure three clones, Iruka failed him despite Mizuki's false sympathetic reconsideration. When Mizuki tricked Naruto into stealing the Scroll of Seals, Iruka tracked down Naruto before realizing too late that the boy was set up.Iruka watches horribley as Naruto finds out that he is a jinchuriki. While Mizuki tells Naruto that Iruka hates him, Iruka remembers the talk that he had with Hiruzen. Upon learning that Naruto was exactly like him growing up. Therefore Iruka protected Naruto from Mizuki's attacks which surprised Naruto. Once Iruka tells Naruto how similar they are, and how he fail to be there for him from the start, Naruto runs off now knowing that Mizuki's earlier conversation with him was a lie.
Now protecting Naruto regardless of him learning the truth, Iruka insisted that he never hated Naruto and sees him as only a ninja of their village. Witnessing Naruto create a high amount of Shadow Clones after being spurred by his faith in him, Iruka allowed Naruto to graduate from the Ninja Academy. Naruto happyily cry in joy, and hugged Iruka for always acknowledging him from his childhood. Iuka gave Naruto his own forehead protector, since Naruto always admire Iruka wearing it during his childhood.
Iruka was next seen asking the Third Hokage if Naruto has handed in his Ninja Registration report. He then learns the truth why Minato sealed the Kurama inside Naruto, and why Naruto had such a heavy burden by the villagers. Iruka realizes that Minato wanted the villagers to look up to Naruto as a hero, and not as the host of Kurama.
Iruka was next seen announcing that Naruto, Haruno Sakura and Uchiha Sasuke were now call Team Kakashi. He told Naruto that he had the worst scores in the Ninja Academy, while Sasuke had the best scores. Which made them be combine to a team. He was happy knowing that Naruto will get along with Sasuke and Sakura. Iruka was next seen finding out that Kakashi failed all his students, and was hoping that Kakashi won't fail Naruto, Sasuke and Sakura. His voice was then heard in fourteenth episode, narrating the background of Squad 7 before they show up to fight Haku.
Chunin Exam arc
When Team 7 is entered in the Chunin Exams, Iruka voiced concern and as such, in the anime, he personally tested each member individually to see if they were ready by disguising himself as a Amegakure ninja.

Invasion of Konoha arc
During the invasion of Konoha, Iruka escorted his students to safety in the shelters behind the Hokage Monument- promising that he and the other instructors would protect them "even at the cost of our lives". He shared ominous looks with Sarutobi Konohamaru when Hiruzen's representation cracked, when they were enter the Konoha shelter. He was seen later comforting Konohamaru during the Third Hokage's funeral, in which Naruto looked at them sadly, since he was standing right next them. Naruto then told Kakashi that he get's Iruka's speech, and Kakashi's words about Hiruzen's will a little bit, in which Iruka smiled at Naruto for. Naruto then waved goodbye to Iruka, and told him that he will see him later. Iruka happily watched Naruto run to his teammates, and spoke to Hiruzen in his mind that the Will of Fire will bring Konoha a new Hokage.
Search for Tsunade arc
Iruka met Naruto at their favorite place to eat, and listen to Naruto talk about his adventure. He later explained to Naruto that they have to do many missions to show other villages that they were still strong, even though their strength had been cut in half. Iruka along with some of the villagers witnessed Naruto and Jiraiya bring back Tsunade as the new Hokage. He then attended Tsunade reign ceremony as the Fifth Hokage.
Pre-Shippuuden Filler arc
In the aftermath of the invasion, Iruka was forced to suspend his teaching duties in order to go on missions and fill the void in personnel. In the anime, he was assisted by Pakkun to find Mizuki and go after Naruto and Tonton. When Iruka caught up, they send Tonton back to the village and Pakkun leads Naruto and Iruka to Shizune. Shizune led them in pursuing Mizuki, when they soon fell into a trap. Iruka then revealed that Shizune is not Shizune but Mizuki himself. While Naruto battles with Fujin and Raijin, Iruka battles it out with Mizuki. Iruka wanted to bring the "old" Mizuki back, but Mizuki revealed that he was only nice to Iruka because he is Sarutobi Hiruzen's favorite. Mizuki led Iruka into a building used to test Ninja Academy instructors and battled there.
After that, Naruto and Pakkun caught up with Iruka and they went to Mizuki's lover, Tsubaki. Tsubaki helped them reach Mizuki but it was too late. Mizuki had drank a formula and became stronger and monstrous. They battled again with Mizuki having the upper edge. Iruka came up with a plan to trap Mizuki, giving Naruto a chance to use Rasengan on Mizuki. He told Naruto that he did great,and that the jutsu he used was wonderful. He then told Mizuki that Naruto will keep getting stronger in the future, and that Naruto's nothing like him. As Naruto waved to Haruno Sakura, Iruka thought that Naruto saved him the way he did for Naruto back then. He then decide to gave the squad a bowl of Ramen as award for completeing the mission. But the celebration was cut short, when Tsunade told that he and Naruto have to go to Konoha Hospital in order for their injuries to be heal, which disappointed them both overall.

Fourth Shinobi War arcDuring the Fourth Shinobi War, Naruto and Killer B, as the last two jinchuriki, were confined to an island to keep them out of Akatsuki's clutches, (Naruto being unaware of this, and the war). After Naruto began to get suspicious and tried to leave, a handful of shinobi tried to stop and convince him to go back in. Iruka was among them, and he convinced Shibi Aburame to let him talk to Naruto. Iruka attempted to trick Naruto into believing he had a second mission on the island. However, Naruto decided to go outside anyway and used Sage Mode to barge past the guards, in the process losing his forehead protector. Before he could leave, however, he was bound by the Shadow Imitation Technique by a Nara clan member, but not before he sensed the war raging outside.
With Naruto demanding the truth, Iruka revealed that there was a war raging in order to protect him, and tried to persuade him not to intervene and risk capture. When Naruto declared that he would end the war on his own, Iruka said that Naruto so stop acting like a kid, and that this war is to protect him. Naruto stated that it was Iruka who first recognized him and gave him his forehead protector, and asked him why he doubted his power now. After hearing Naruto's response, Iruka admits that Naruto was like a little brother to him, and he wouldn't be able to bear it if Naruto was captured.
Glancing down at Naruto's fallen forehead protector, Iruka decided to return it to him, only to erect a barrier to trap Naruto. Naruto however enters his Nine-Tails Chakra Mode and easily breaks out of the barrier and resisted all attempts to subdue him, before making his way to the battlefield. On his way, Naruto found a note in his forehead protector, from Iruka, telling him to come back alive. When Killer B arrived, Iruka told him to protect Naruto and they bumped fists. The Eight-Tails told him that he couldn't keep an eye on Naruto but B said no one could, and said to Iruka that he was in Naruto's heart and everything he taught was still inside, even today.

Many years later in Konoha, Kakashi assigns all the wedding's attendees a mission that is to be kept secret from Naruto and Hinata: bring a gift. Shortly after he received his invitation to the wedding. Naruto while waiting at the Ninja Academy, approached Iruka. Naruto asked Iruka if he would attend the wedding as his father, since his own father is dead. Iruka happily agreed after Naruto asked him this, and soon afterwards Naruto left. As soon after Naruto left, Iruka was overwhelmed with emotions, something that now reoccurs every time he sees naruto listed on the menu at Ichiraku Ramen. Iruka can't help but feel indebted to Naruto, whose presence first in his classroom, and now in his life pulled him out of the self-pity he experienced following his parents' deaths and convinced him to dedicate his life to teaching; were it not for Naruto, Iruka worries he would have turned out like Mizuki.
Iruka buys a wedding gift before stopping by Ramen Ichiraku, where he smiles upon seeing since Iruka now realized that he won't get to hang out or have dinner with Naruto as often; because Hinata will now be cooking for him, and will do this with him for now on. When he gets home, he looks at the disarray and disrepair he lives in, and resolves to find a life partner just like Naruto has. (In the anime, his gift was to send a video message to Naruto. But he had a hard time trying to figure out what to say). In the end after he spoke to Hinata by comforting her about her own problems, he is put at ease since they both know Naruto the most. After Naruto asks him to attend his wedding as his father, Iruka and Hinata talk about Naruto's request. Iruka records another message with Konohamaru, finally getting it right.
On the day of the wedding, guests start arriving at the ceremony to be held under the Hokage Monument. Iruka is shown becoming emotional as soon as he arrives at the event.
Many years later after Naruto's wedding, Iruka now retired from being a instructor at the Ninja Academy, while leaving the job to Shino. He continued to watch Naruto grow. He was proud of him becoming the Seventh Hokage, and had attend the ceremony alongside Sakura and her daughter, Sarada. While at the ceremony he speaks to Sakura and Ino. When he saw Naruto wave to everyone, Sakura asks Iruka if something was wrong. But Iruka told her that he was alright and he continues smiling while thinking about that Naruto will have a tough road ahead of him.
Iruka attends the entrance ceremony for the new students. Ultimately, he and the other instructors were left mortified when Boruto crashed a train into the Hokage Monument. However Iruka became the principal of the Ninja Academy. When the Ninja Academy had a new transfer student, Mitsuki, and Shino was having problems keeping the class in line, Iruka offered to have Anko help out. While asking Anko if she seen Shino, Iruka becomes very worry for Shino.
After Kakei Sumire turned herself in as the culprit behind an attack on the village, Iruka was given the report. While Shino insisted to let her return to the Ninja Academy under his supervision, Iruka noted that despite the leniency presented to her, the nature of her retuning was still depending on her choice.
Then on the day of the Five Kage Summit being held in Konoha. While noticing that Boruto inherited Nauto's hobby of pulling pranks just to get attention. The same situation that he himself faced with Naruto back then. Konohamaru responded back to Iruka that just like Naruto, that he himself is too soft as well. But he told Konohamaru that he is the same like him and Naruto since the latter is now a Jonin. Once Naruto and Boruto came to him and Konohamaru. Iruka watches as Konohamaru scolded Boruto for the prank, to which Boruto didn't care which annoyed Konohamaru. After Konohamaru scolded Boruto, Iruka was seen smiling at Naruto and Boruto.
In the anime, to improve relationships with other villages and symbolically show the warring era was over, the Seventh Hokage set up an official class trip for the Academy to go to Kirigakure. Upon presenting this idea to Iruka, the principle admired this bold step to easing remaining tension from the previous warring era and approved the idea. Before the students left for the field trip, Iruka talks about the past with Naruto. However he and Naruto caught Boruto outside his office, for trying to do a technique as Iruka saw it as a prank instead of Boruto being in class.
After the class returned from the trip, Iruka received a letter from the Sixth Mizukage about the events, learning that Boruto, Sarada, and Iwabee aided Chōjūrō in stopping a coup d'état. When confronting the students about it, after Boruto tried to get out of trouble with a longwinded story, Iruka had the three students repaint a classroom as punishment.
As the ninja classes began preparing for the graduation exams, Iruka requested that Kakashi be a proctor, which the retired Hokage agreed to. On a unique decision, Kakashi decided to get a better understanding of the students by posing as reporter and interview them. Afterwards, Iruka requested that Kakashi go easy on the students during the exams. Kakashi however insisted that they can't have students pass with the wrong type of mentality and as such would not hold back on them.
Ultimately, Kakashi passed all the students after they showed true team-work and loyalty towards each other. Despite this, Iruka was still very annoyed at how intense Kakashi was on the students.
Iruka was only seen in a Flashback with Naruto eating at Ramen Ichiraku with him. This was shown when Naruto was in a prison cell with Kazahana Koyuki trying to break the chains that were holdind his arms together.
He made a cameo with Kakashi when Konoha received an urgent message from the Land of Demons. he later joins Hatake Kakashi, Tenten, Maito Gai and Mitarashi Anko in launching a counterattack against Moryo and his stone soldiers to buy time for Uzumaki Naruto, Hyuga Neji, Haruno Sakura, and Rock Lee, who were protecting Shion, to defeat Moryo. He was later seen with Kakashi after the stone soldiers retreated.
Iruka is seen in a flashback by Naruto and lastly in a vision by him to gather engery for Sage Mode.
Later while eating at the Ichiraku Ramen, Naruto meets Iruka. He then asks Iruka for a letter of recommendation of his own, but Iruka refuses as Naruto is only a genin and must become a chūnin and rise through the ranks just as Minato and all other jōnin did. Naruto complains that Minato's face is curved as a rock, and doesn't say "Welcome home". Naruto admits to Iruka that he wished that his parents were alive, and not dead.
Naruto even told Iruka, that both of their parents were killed by Kurama. Iruka then gets mad at Naruto for the comment. He then asks Naruto what's the problem, and Naruto says nothing. Teuchi then hands them their Ramen, but Naruto asks him about the Naruto fish. Teuchi tells Naruto that they ran out of it, and gave Naruto some Menma instead. Naruto then gets angry, and tells Teuchi that he dislikes Menma. Iruka then yells at Naruto, and grabs by his jacket. However Teuchi tells them to take the fight outside. But Naruto then yells at Iruka about the Menma, and slams the money he had in his pocket on the table, and rans out of the bar stating that no one understands him at all. Iruka yells out Naruto's name while he's running. However he sits back down as Teuchi tells Iruka that he didn't know that Naruto disliked Menma, and Iruka told Teuchi that he pay for Naruto's meal.
At the end of the film, as Naruto goes home, he sees Iruka in his house, waiting to apologize to him. Iruka shows Naruto a cake, and Naruto shocking cries after he realizes that Iruka really does care about him. Iruka asks him what's wrong, and Naruto says nothing. Iruka welcomes Naruto home, and Naruto says I'm home to Iruka.
He was mostly shown in flashbacks from Naruto's days at the Ninja Academy when asking Naruto and all the other students to write down the name of the person who they would want to spend their last day with if the Earth was going to be destroyed. He scolded Naruto for making a paper airplane rather than writing down a name while the latter stated it was cause he has no friends or family and that the world wasn't ending.
Not counting flashbacks, he later appeared amongst the villagers evacuating to an underground shelter to take cover during the meteor shower. Then he is seen celebrating with everyone when they hear the worldwide announcement about the Moon crisis being averted. He was lastly seen during the end of the film at Naruto and Hinata's wedding.

Umino IkkakuUzumaki Naruto, before eventually deciding to be strict with the boy so he could work harder and reach his own potential. In time, learning from Hiruzen that the boy acted out with his antics to be acknowledged as he had in his youth, Iruka understood Naruto's loneliness and went out of his way to connect with the boy outside the classroom — treating Naruto like a younger brother. As a result, after Naruto learned of his nature as a jinchuriki and Kurama's role in the deaths of his teacher's parents, Iruka confidently believed in Naruto as a ninja of their village and nothing else. Ultimately, Naruto began looking to Iruka as a Surrogate father, as he admitted it to Sasuke at the Valley of the End.
Even after Naruto graduated, Iruka still treats his former student at the Ramen Ichiraku bar whenever he returns from a mission. Though times like that allow him an opportunity to see how Naruto is developing as a ninja, Iruka still tends to worry about him. During the Fourth Shinobi War, Iruka was among the ninja assigned to keep an unaware Naruto safe from the army that Obito amassed to take him and Killer B by force. But once Naruto learned of the war, Iruka attempted to talk Naruto out of participating in the fight until the youth reminded him of the confidence he had in him years ago. Staging an apparent capture of him while secretly giving his former student a message to come back alive. Naruto, upon reading the message, swallowed it to keep his sensei's words close to him. Iruka was assured by Killer B that he and his teachings are with Naruto in his heart.
Iruka was free from the genjutsu after Naruto and Sasuke ended the war. Two years after the war, when Naruto was getting married to Hinata, he had asked Iruka to be his 'father' for the ceremony, bringing Iruka to tears. Iruka then attended Naruto and Hinata's wedding. He congratulated them while being tearfully happy over seeing Naruto becoming a man. He was seen putting the flower on Naruto's suit and was also his best man at the wedding.
Years later after the Fourth Shinobi War, Iruka watched on proudly as Naruto finally achieved his lifelong dream of becoming Hokage. Iruka also notes that Naruto's son Boruto acts just like his father by inheriting his father's hobby of pulling pranks just to get Naruto's attention. Iruka even attended the Chunin exam finals to watch Naruto's son fight against Shikamaru's son Shikadai, hinting that he still respects his favorite former student's new family.
Iruka gets along very well with Hinata, even to the point when he informs that Boruto is ditching his classes at the Ninja Academy.
