Yukio Okumura (奥村 雪男 Okumura Yukio) is Rin's younger, fraternal twin brother. A straight arrow and kind-hearted by nature, he is the youngest person to ever pass the Exorcist qualification exam, attaining a Meister in Doctor and Dragoon, and later becomes a teacher at True Cross Academy, where he ironically ends up teaching his older brother in the ways of the Exorcist.
In the anime, he is seen with a mysterious black mark on the underside of his left arm that is now starting to spread throughout his body. This may have something to do with his original birthright as Satan's son and the Demonic powers he was supposed to have shared with Rin as Yukio was shown preforming his daily testing and it reacted, but the mark was never fully explained in the anime (though Shura appeared to be alarmed by the sight of it).
As of the last episode, Yukio's mark has spread all the way down past his elbow.
In the anime, since awakening his Demonic powers in episode 22, Yukio now possesses the same Demonic features as his brother, Rin, when in their human form (e.g. the slightly pointed ears and sharper canines). When in his Demon form, he too has a blue flame, elf-like ears and fangs.
He has teal eyes and dark brown hair. His most notable trait is two moles under his left eye and another one under his mouth.
Yukio is mostly seen as quiet and calm, but often has mood swings. He is usually seen happily smiling, but can easily get sidetracked due to Rin's personality clash, and becomes rather dark. He takes things seriously, but he knows a joke when he hears one.
On few occasions he is shown to have a very aggressive side. If he is pushed too far, he can gain a fiercely angry personality. His angry side is so intense that it frightens Rin when it makes itself known. This may be as a result of his Demonic heritage even though he didn't acquire Satan's flames like Rin. He is a big worrywart and often overthinks about situations. He is often seen sleeping anywhere, such as on a chair or on his desk, while thinking.
He doesn't like to partake in 'unseemly' actions. He is usually punctual and lectures Rin on how to behave. He has good control over his anger and tries his best to be calm and composed.
Yukio, along with Rin, was conceived during his mother's possession by Satan. Though Satan's powers were expected to be split between them, Yukio's body as a fetus proved too weak to handle the Demonic power, which completely transferred to Rin. Nevertheless, Yukio did receive a mashou at birth, causing him to be able to see Demons ever since he could remember. He was always bullied by other kids but Rin would save him. His dream was to become a doctor. He thought he was weak and wanted to become stronger, then Father Fujimoto approached him and asked him if he wanted to become an Exorcist.
Yukio secretly trained to become an Exorcist since age seven in order to protect Rin (through the help of Shiro Fujimoto). While both Yukio and Rin are in their first year at True Cross Academy, Yukio is already an instructor at the Exorcist cram school who teaches Anti-Demon Pharmacology to Rin's class. It is often stated that Yukio is a genius, having already acquired the title "Meister" in both the Dragoon and Doctor class, while ordinarily most people would aim for Meister in one class (both are still fully qualified Exorcists). He is currently ranked a Middle First class Exorcist.
True Cross Academy arc
Yukio was accepted into the True Cross Academy. He began packing his things, then when he finished he went to Fujimoto to see how he was doing. There he also saw Rin. Father Fujimoto then asked him if he could heal Rin's wounds. While he was treating Rin's wounds he told Rin that everyone at the church was worried about him getting fired from all his jobs and getting into fights all the time. Then the next day before Yukio would leave, Father Fujimoto suggested that they will have a party to celebrate Yukio's success. When everyone sat at the table waiting for Rin, Yukio went to look for him. He found Rin on the playground. There he questioned Rin as to why he was fired from his job. They went home together.
When they arrived, Yukio and Rin saw a man and his daughter speaking to Father Fujimoto. When Rin suddenly claims that it wasn't human who attacked the girl but a weird creature. Yukio, was surprised that Rin saw the Demons. After they all went to celebrate Yukio's farewell party.
The next day Yukio went early in the morning to the True Cross Academy because his things were sent earlier. He left a note to Rin informing him of that. While Yukio was at the station he called Fujimoto to see if everything was alright, but Fujimoto didn't answer. Yukio thought that something was suspicious and went back.
When Yukio got back home, he was surprised to find the church totally destroyed and the deceased Fujimoto laying on the ground. He also noticed that Rin awakened his powers.
The next day, Yukio went with Rin and Mephisto Pheles to the True Cross Academy. There Yukio gave a speech in front of everyone. He was the center of all gossip and everyone was amazed that he had the highest marks on the entrance exams.
When Rin entered his Exorcism class, he was surprised to see Yukio as his teacher. There both brothers began to argue with Rin demanding an explanation from Yukio as to why he is involved in all this. Yukio promptly sent the class out into the corridor when Rin spilt blood on the floor, attracting Demons. Yukio then said that he could see Demons since he was born. Then Goblin Demons attacked them after the blood spilled. They both fought the Demons together. At one moment Yukio seemed like he was going to shoot Rin for killing Father, but he didn't. Yukio then asked Rin how their father's final moments were. Rin answered that he was very cool. The class then came back into the room shocked of the state of the room.
Then, after, Yukio and Rin went to their rooms, only to Rin's surprise they were sharing one room. Yukio told Rin that he would need to keep watch over him at all times. Rin then agreed to Yukio's challenge.
The next day, Yukio found Rin reading his manga. He told him that instead he should concentrate on his studies. He told Rin that he needed to go to do a request and go shopping while he's at it. Rin then offered to go with him, telling him that it is a better way to study for him. Yukio said that he could come.
When they arrived Yukio went inside the shop to greet Shiemi's mother who told him that Shiemi's legs are getting worse and worse. He then said that he will have a look at them. Entering the garden, he saw Rin and Shiemi together. He asked Rin why he was there and then told Shiemi that he should have a look at her legs. At first sight he concluded that it was the work of a Demon. He asked Shiemi if she had had any contact with Demons. While declining, Shiemi collapsed. After that they took Shiemi back to her grandmother's room. Yukio and Rin talked to her mother about how she never had any time for Shiemi.
When Rin and Shiemi were talking, Yukio came and told Shiemi that they will be able to exorcise the Demon. Angered by this the Demon revealed itself and used Shiemi as a shield. Yukio asked Rin for help which he gladly gave. Yukio realized that he had no other choice but to fire a harmless bullet, tricking the Demon and giving Rin a chance to kill it. After the Demon was killed, Shiemi went to apologize to her mother.
The next day, Yukio introduced Shiemi to the whole class as a new student. Then continued the lesson.
Training Camp arc
Yukio along with Shura are head of the training. He leads the Exwires to the camp location and explains the task to them. While the Exwires venture into the forest, Yukio stays at camp with Shura. A signal flare is sent up shortly after and Yukio goes to retrieve the ExWires
who needs help. On exiting the camp Yukio is attacked by a swarm of moth Demons and surprised at how many and how aggressive they are. While he is fighting the moths, Rin starts fighting Amaimon. Yukio arrives at the battle just as Rin makes a motion to draw his sword. Yukio calls to Rin, saying it is a trap, but Rin draws his sword anyway. Yukio retreats to the Exwires. When Rin is subdued, he stays behind with the Exwires to explain his and Rin's parentage.
Impure King Revival arc
Interrupted from a match with Shura. Yukio was sent on a mission to track down the thief who stole the Left Eye of The Impure King. At the scene, a woman with her son named Satoru were walking by as Exorcists told them to move away as the Eye might've been close and may cause infection. Compelled by this Satoru runs past the Exorcist and he is taken hostage by the thief.
Hearing the Satoru's incident, Rin spots Satoru's mum and promises her that he'll save her son. Unsure of Satoru's safety, Yukio corrects Rin and tells the woman that it is not confirmed that her son will still be alive. Yukio tells Shura to keep an eye on Rin as he and Saburota Todo enter an abandoned apartment where they believe the thief is inside.
As soon as the canary stops singing(meaning that poison gas is nearby) they manage to corner the thief taking Satoru hostage, the thief cracks the glass bottle holding the Eye and as it releases a gas, the thief manages to escape, but that eye was a fake. Saburota betrays Yukio and knocks him down with a kick. Yukio turns his head and sees a Demonised Saburota. Shocked by this, he tells Rin(who just happened to get rid of Shura) to quickly take the boy and run. Yet still in fear, Yukio cured Satoru from his infection and returned him to his mother. It was later then revealed that the scene was a scheme and now the real Eye has actually been stolen.
Yukio and other Exorcists were sent to track down the Eye.
While hiding in the bushes, Yukio encountered a Demonised Saburota. But instead of attacking him in an instant, Saburota talked Yukio into his true feelings towards Rin. Attempting to stop this, Yukio uncommonly swore and tried shooting him. Being Demonised, Saburota dodged the bullets with ease. Yukio tries hiding within the forest to prepare a solution to getting rid of him, but that doesn't refrain Saburota from continuing their agonizing conversation of growing up to be a weak, feeble being of the world.
Terror of the Kraken arc
True Cross Academy Festival arc
Shura bumps in to Yukio and tells that a large numbers of demons are gathering at a waste research facility but she is unsure if it is related to the demon eaters.
Exorcist Exam arc
He is seen trying to forcefully awaken his demonic powers.Mephisto summons Rin and Yukuio to investigate the whereabouts of Shura Kirigakure.
Mephisto Pheles orders Yukio and Rin Okumura to go to Towada Shrine in Aomori prefecture to track down and bring back Shura. Yukio tells Mephisto he would rather go alone, which angers Rin. Mephisto then firmly tells him not to argue and that it is an order. He also tells Yukio that one of his sources told him about the dangerous training he has been engaging in. He looks shocked as Rin asks about the training. Yukio then quickly asks Mephisto a question but is quickly cut off by him. Mephisto tells him that training is not an issue, but not to endanger his life. He then tells Yukio to use the trip as a chance to blow off some steam.
Aboard the train bound for Aomori, Rin is excited as usual about traveling. Yukio asks him if he is ashamed of himself, to which he says why should he be as they were ordered to blow off some steam. Yukio then quickly reminds him that they are there to find Shura. Rin acknowledges him before quickly cutting him off and then exclaiming about eating bento from the train station. After arriving at the station, Yukio suggests asking around to see if any of the locals had seen Shura. Eventually, they get a lead from a taxi driver, saying he drove her to Lake Towada.
Arriving at the lake, Rin complains about most of the shops being closed. Yukio reminds him that it is the off season and it's 4 in the afternoon. Soon after, Rin asks about where they should stay. Yukio says that he will ask about lodging. He then spots an inn that has some lights on.Upon entering the inn, Rin says it is creepy while Yukio calls out to see if anyone is there. A lone voice then answers back. A little old lady emerges from the darkness and asks if they will be checking in. Yukio then asks her if they have a room for two to which she replies that they have plenty of open rooms. Pleased with her answer, Yukio tells her that they would like to stay. She asks if they came to sight see even though it is the dreary season to which Rin excitedly answers yes. He then asks if they have an outdoor bath and she says that they do, much to Rins excitement. Yukio then interrupts him saying that they have work to do. the little old lady tells them not to pretend and that folks tend to do as they please and that she is not one to judge. Yukio flashes a confused look, seemingly confused by the woman's words. Arriving in the room, she asks if it is alright. Yukio says that it is while Rin marvels at the view of the lake from the window. The woman then tells Yukio that they may reserve a private bath.
The woman continues on, telling him that that way, they do not have to worry about what other guests will think. Yukio looks confused and worried as Rin chimes in saying that he prefers an outside bath, before asking Yukio if he does as well. Yukio sheepishly responds that he does. The woman then responds that she will ensure no one disturbs them and that they can enjoy themselves however they wish. Yukio quickly cuts her off, yelling that she does not understand. Rin, totally oblivious to the innuendo being applied, then happily suggests that they hit the outdoor bath.
Outside in the bath, Rin cannot help but to be excited as usual while Yukio comments on how exhausted he is. Rin asks Yukio if he wants him to scrub his back and Yukio quickly tells him no thank you. He then lets out a sigh and comments that he wishes he could be as laid back as Rin is. Rin then suddenly has an outburst, saying that the mission so far has been a blast and apologizing to Shura. After calling themselves the Exorcist brothers, Yukio pies in saying that is a stupid name. Rin then tells him not to be like that and then asks him to talk with him. Rin then immediately asks about the "dangerous training" Mephisto spoke about. Yukio looks quite surprised when Rin asks. Rin asks if Yukio is ok after he does not respond. He says that he is fine and that the training is just shooting practice.
Yukio quickly changes the topic and asks Rin how he has been doing. Rin go's on to explain that he accidentally told Shiemi that he liked her. Yukio seems quite surprised by Rins admission. He then asks Rin about what she said. Rin tells him that Shiemi said that they were just friends. He then says that he should not have said anything and that now, things will be weird between them. Rin then says that he thought Shiemi liked Yukio but said they are just friends also. Yukio tells him that he does not understand anything, that she is a good student and looks up to him, and always has since they met. He then says that if she knew the real him, that she would despise him. Rin is surprised by Yukios statement and say the Shiemi has said she admires him and would never say she hated him. Yukio then says that he is getting dizzy and that he is getting out of the bath.
Powers & Abilities
Yukio is an extraordinary Exorcist, and was instructed by one of the most powerful Exorcists in the world, Shiro Fujimoto. He obtained his official Exorcist license at the age of thirteen, as well as becoming the Order's youngest teacher, specializing in Anti-Demon Pharmacology, at the age of fifteen. Due to his unique heritage, he acquired a mashou from Rin at birth.
Despite his youth, Yukio's medical abilities are top notch. He was able to treat Noriko Paku after being injured by a Naberius that Igor Neuhaus summoned, after being treated by Shiemi. In the manga, during the theft of the left eye of the Impure King, he cured a child named Satoru by inserting needles into the miasmatic boils on his body without rupturing the membranes of the cells, demonstrating advanced knowledge of cellular biology. This is made further impressive as at the time, Yukio was also infected by the miasma while left reeling by the words of a possessed Saburota Todo. When he and his brother were young, he would treat Rin's injuries whenever he came home after getting into a fight.
In addition to his medical skills, Yukio's competency in his Meister extends to teaching. He is considered to be a qualified teacher of basic Anti-Demon Pharmacology at the age of fifteen, and is the youngest person in the order to do so.
Yukio's second and offensive Meister is Dragoon, a gunslinger. Yukio can shoot his targets with impressive accuracy, all the while maintaining a calm and even disposition. He has demonstrated the ability to shoot Demons behind his back without even looking at them, as well as destroying giant Demons with his hand guns. Yukio's weapons of choice are dual handguns that may have been modified for rapid fire. He is able to keep up with Shura, an Exorcist 2 Ranks above him, in a combat simulation test. Yukio also has some knowledge of the fighting elemental Demons, as shown when he fought a fire Demon using water-attributed bullets. In the anime, he has also been seen using a shotgun.
Although Yukio does not have a Meister as a Tamer, he is able to summon multiple Naiads and also perform a spell with them. However, his lack of stamina in summoning Demons makes it difficult to maintain the summoning for long periods of time. Saburota notes that this was the first time Yukio has summoned demons.
- Naiads (
水精Naiasu): Water demons
Demon Form (Anime Only)
He is shown to have Demonic powers in him later in the anime, allowing Satan to possess him without any danger as a perfect vessel. He also is shown to have blue flames much like Rin and his blood is that of a Demon's.
Although his Demonic form has only been revealed in the anime, it has been revealed in the latest chapters of the manga that Yukio has, indeed, inherited some of Satan's Demonic powers. Whether or not this results in Demonic physical characteristics has yet to be shown. They say that his eyes were not his and his vision turned blue all of a sudden, the meaning of this is as yet unknown.

- (To Rin Okumura) "You utter fool, Nii-san... Why did you come up with this ridiculous idea of becoming an Exorcist? Revenge? Some kind of twisted sense of atonement towards Father? If you truly have the nerve to feel that way... then you should give yourself up to Order Headquarters... or just die, please."
