|“||I'm not a human or a demon anymore. I have no choice but to go forward! I'll become an Exorcist!||„|
|~ Rin's resolve|
Rin Okumura is the main protagonist of the manga/anime, Blue Exorcist. He and his younger twin brother, Yukio, were born from Satan and Yuri Egin. He attends the True Cross Academy to become an Exorcist and get revenge on Satan for killing his adoptive father, Shiro Fujimoto.
His physical appearance is that of black hair (in the anime, it has a blue hue), which is a bit longer than that of Yukio's, and pale skin. While in his human form, Rin exhibits a number of physical traits that are signs of his demonic nature, such as sharper-looking teeth, slightly pointed ears, and a black, fur-tufted tail (he keeps it hidden under his shirt). As a demon, Rin gains two blue flames that look like horns floating above his head, long elf-like ears, and his pupils turn red while his irides remain bright blue. The blue flames also blaze around other places of his body, mostly at the tip of his tail. Before going to the True Cross Academy, Rin was often seen wearing a blue hoodie, and a pair of black jeans with chains on the side, giving the impression of a rebellious nature. He was also seen wearing a white jacket with big pockets and various decorations on it and a pair of gloves. Because of how often he got into fights, Rin was seen with band-aids over his cheeks and fingers, which were usually taken care of by Yukio. While in True Cross Academy, Rin wears the school's uniform, which consists of a white shirt, a necktie, a black jacket, and black pants. He is also seen carrying around Kurikara. Also in class, he is sometimes seen with his bangs pinned up so he can read his studies.
Rin has a protective and supportive personality. He can be very violent and get into fights (possibly caused by his demon side), but really has a kind heart. He supports his friends and tries to encourage and help them. He also seems very protective of Yukio, and aims to surpass him one day. However, Yukio often finds Rin annoying due to his frequent impulsiveness and stupidity, which makes Yukio look down on Rin as much as up and makes it hard for Rin to be taken seriously by Yukio and even others, making Rin desperate to earn his brother's approval. He takes offence when Yukio accuses him of killing their father and pointing a gun at him, warning him not to insult him and saying that he isn't going to fight his brother.
Although he generally hides it, Rin loved his adopted father a great deal, and has nothing but good things to say about him. He deeply regrets that the last thing they did was fight, which resulted in Satan taking him over. Much like Yukio, he takes any insult against him very seriously, and got really angry when Shura claimed he died like a coward. He also doesn't like people insulting Yukio, who he loves and greatly respects. Besides this, however, Rin is surprisingly even-tempered and laid-back, and rarely gets angry without a good reason.
Rin is often shown to be able to relate to people easily and connect their feelings to his own, such as Shiemi Moriyama's grief over her grandmother and Ryūji Suguro's ambition to defeat Satan. He's also able to understand Shiemi's desperate desire for friends, as he grew up with almost no friends due to being constantly harassed by bullies and being called a demon. In general, he is often the first one to try and make people feel better if they're down. He's not the type of person for school or studying, though he was able to gain a junior high diploma and become an Exwire.
Unlike his brother, Rin is immature, which leads other people into believing that he is younger than Yukio; it's been noted by several people that despite being twins, he and Yukio couldn't possibly be more different. He is headstrong (literally as well as metaphorically, as he was able to stop a charging demon by directly headbutting it in the forehead) and is often very open with his friends. However, when his friends found out about his demon heritage, they become afraid of him, thinking that he is unstable which could lead to a disaster, but they slowly got used to him and accepted him during the Kyoto Arc.
Despite his usual hot-blooded, headstrong attitude, Rin is often shown to be more sensitive than he lets on, which is shown when he cries from reading an emotional drama manga. He is also shown to have a soft spot for animals. In the beginning of the manga, the reason he had gotten into a fight with Reiji Shiratori and his delinquent gang was because they were torturing pigeons. He also attempts (successfully) to tame Kuro without killing him after hearing that he was once Shiro's familiar.
During the time of the Blue Night, when Satan murdered a huge number of the world's greatest holy men, in order to find someone who he could possess without any ill effects to save Yuri Egin, who was going to be executed by the Vatican for being impregnated by him, Shirō Fujimoto and Mephisto Pheles were ordered by Yuri's father, Ernst Frederik Egin, to go find and kill her and Satan's children. They found Yuri within the forest with her newborn twins, whom she named Rin and Yukio, and she soon died of childbirth. Instead of killing the twins, Shirō decided to seal Rin's demonic powers within the demon-slaying blade Kurikara with the help of Mephisto, and raise Yuri's children as his own.
In his childhood, Rin lead a normal human life, but his strength and temper seemed unnatural, so all the children and even teachers feared him and thought of him as a demon. He got into fights often and injured all his classmates, and the only one who could stop him was Shirō. Rin always admired Shirō and wanted to become like him when he grew up. Rin always protected Yukio from bullies and encouraged him to chase his dream. Also in his youth, Rin learned how to cook, which became his natural talent.
Plot and Story
After getting into another fight with Reiji Shiratori and his gang, and being fired from another one of his part-time jobs, Rin's guardian, Shirō, strictly reminded Rin that he would have to make a living on his own someday. After Yukio treated Rin's wounds, Yukio asked him if he would be alright without him around since he was going to move from the church. Rin admitted that he was also worried, but he said that he had done nothing wrong. After being prompted by Izumi and Maruta on going to the job interview, Rin saw Shirō consulting a girl named Yui Sakamoto and commented that being an Exorcist must be hard with having to get rid of things that don't even exist, to which Shirō disagreed and claimed that demons exist within human hearts.
Later, after Rin called Yukio that he was able to get a job at the supermarket (with the help of his natural talent at cooking), he saw Yui chasing after her scarf. When Rin caught the scarf and was about to give it back to her, he suddenly saw a monkey-like creature there took the scarf out of his hand and ran off. While Rin was chasing after the creature as they thrashed around in the supermarket, it suddenly went on top of some boxes, which were going to fall on Yui. Rin protected her from them, but the girl fell unconscious. Shirō, Yukio, and the others were waiting for Rin to come home to celebrate, but Rin was nowhere to be seen. Worried, Yukio went outside to look for him, and eventually found Rin at the park. Rin told Yukio that he was too ashamed to come home after he got fired from his job, but couldn't explain him why. Then, when they both arrived back home, Rin saw Yui again, along with her father, who came by to thank Rin for saving her.
The next day, after he woke up and saw a letter from Yukio saying that he had to leave earlier than planned, Rin started to see a lot of small black creatures floating in the sky. He went outside and began to wonder why no one around him was noticing them. Then suddenly, Reiji and his gang appeared and asked Rin to come along with him to have a talk. At the alley, Reiji said that he came to apologize and tried to give Rin some money as a request for him not to mention about the fight that they had the other day, as it would damage his own reputation and his chance of getting into the True Cross Academy. Rin declined the offer, but when Reiji said that he should accept the money because his family was poor and that Yukio got into the Academy only for his grades, Rin punched him, saying that he could insult him all he wanted, but not to Yukio. Then, as Reiji was about to burn Rin with a heated steel pole, blue flames started to appear from Rin, surprising himself. Astaroth, the demon whom was possessing Reiji, said that the blue flames were the proof of Satan's offspring and was about to take Rin to him, but Shirō suddenly arrived and exorcised Astaroth from Reiji. Afterwards, a horde of demons started to appear and attacked Shirō and Rin, to which Shirō stated that they won't stop at nothing to bring Rin to Satan.
When they finally arrived home, Shirō and the other Exorcists placed many protection barriers surrounding the chapel. Shirō also gave Rin the sword Kurikara, which was used to seal his demonic powers. Then, Astaroth (possessing Reiji again) and his demon minions started ambushing the church, but the Exorcists managed to defeat them. After the battle, Rin had a harsh argument with Shirō, believing that he was just wanted to get rid of him. Mentally shocked from hearing Rin's accusation, Shirō suddenly got possessed by Satan who came to drag Rin to Gehenna. After Satan opened the Gehenna Gate, Shirō, managing to regain control of his body, stabbed himself in the heart and proclaimed that Rin was his son before he died. As he remembered his memories with Shirō, Rin drew out Kurikara, which returned his demonic powers, and destroyed the Gehenna Gate, leaving Rin and Shirō to remain in Assiah.
After Shirō's funeral, Rin stayed behind at his grave. When he was about to call a phone number of Shirō's friend, a phone near Rin rang. To his surprise, he saw a lot of Exorcists surrounding him with Mephisto Pheles. Mephisto gave Rin three choices: him killing them, them killing Rin, or Rin committing suicide. Rin choose neither of those options and instead decided to become an Exorcist, stating that he didn't want anyone else to die. Hearing this, Mephisto became amused and accepted Rin's idea, letting Rin start at the True Cross Academy.
True Cross Academy arc
The next day, Mephisto brought Rin, along with Yukio, to the True Cross Academy. Rin was surprised to see Yukio was the year's freshmen representative, but was glad to see his younger brother fulfilling his dream of becoming a doctor. While Rin was looking around the Academy, he later met with Mephisto, who warned Rin to control his temper, as his blue flames would easily respond to his emotions and expose his identity as the son of Satan. With that said, Mephisto gave Rin a magic key that allowed him to enter the school for Exorcists from any door. There, Rin met with his classmates and, to Rin's surprise, Yukio entered the classroom introducing himself as a teacher. Yukio revealed to his older brother that ever since he received a mashou from Rin when they were born, he were capable of seeing demons, and Rin was the only one who didn't know the truth. As they argued, a vial of foul-smelling liquid accidentally fell onto the ground, which lured a horde of Hobgoblins. While they were fighting them, Yukio called Rin an idiot and accused him for being responsible for Shirō's death as he pointed his gun at him. Rin said that he was right to call him that, but he exclaimed that he wouldn't dare point a weapon at his own brother as he slew a huge Hobgoblin. After the fight, when Yukio asked Rin of how Shirō's final moments were, Rin answered that he was unbelievably cool. Later, Rin found himself sharing one room with Yukio, even though they were the only residents of the entire dorm. Yukio said that he would need to keep watch over Rin, much to Rin's dismay.
Later, when Rin heard from Yukio that he had received an exorcism request, Rin convinced Yukio to let him come with him, as he would learn more out in the field. While Yukio was inside the Exorcist Shop to buy some supplies, Rin noticed another nearby stairway, which leads to a beautiful garden. There, he saw Shiemi Moriyama, the shopkeeper's daughter. At first, she thought that he was a demon, since he accidentally broke the gate that had a barrier around it, but soon afterwards, Shiemi apologized to Rin as he was helping her with her flowers. After Shiemi talked to Rin about her wish to find the Garden of Amahara, Shiemi's mother brought Yukio to have him examine Shiemi's legs, which were infected by a demon living within the garden. Shiemi suddenly collapsed after she disobeyed her mother's order to abandon the garden for the sake of her health. After hearing from Shiemi's mother about Shiemi's past with her late grandmother, Rin went to Shiemi and told her that her grandmother never wanted her to be a prisoner of the garden. As soon as Shiemi realized that what she had been doing was wrong, an angry Dökkálfr appeared and possessed Shiemi. Rin couldn't directly attack the Dökkálfr since it was using Shiemi as a shield, but Yukio shot a nutrient capsule bullet, letting Rin kill the demon when it was separated from Shiemi. After the battle, Shiemi was able to use her legs again and reconcile with her mother. The next morning, Rin saw Shiemi introduced as a new student in his class, since she resolved to learn more about the world around her, and as thanks to Rin and Yukio for helping her.
A few days after Shiemi's enrollment, Yukio handed out their test results. Rin had 2/100 correct while one of his classmates, Ryūji Suguro, had 98/100. Ryūji criticized Rin and they got into a verbal fight, but were interrupted when Renzō Shima, Konekomaru Miwa, and Yukio held them back. During the class' P.E. session in the arena, Rin and Ryūji competed in a race to see who would be the last one standing while being chased by a rampaging Leaper. Rin proved to be faster than Ryūji, and in his anger, Ryūji kicked Rin and got into another fight, but their teacher Kaoru Tsubaki stopped their quarrel. After Renzō and Konekomaru explained Rin about Ryūji's dark past and his goal to defeat Satan, Ryūji challenged Rin to touch the Leaper without it attacking him, so he could prove that he was determined to become an Exorcist. Rin declined and told Ryūji that he wasn't stupid to risk his life like that because he also had a goal to achieve. That angered Ryūji, so he went down to toward the Leaper himself to prove he was brave enough. However, the Leaper could feel the anguish from Ryūji's mind and was about to bite him, but Rin quickly jumped in and took the demon's attack for him. Rin looked at the Leaper in the eye and ordered it to let go. After that, while back in the classroom, Rin tried to study, but he couldn’t concentrate because his bangs were in the way.
However, Ryūji then came to Rin and loaned him a hair clip to put his hair up and thanked him for saving him. Rin was surprised and thought it was creepy and an omen, which annoyed Ryūji. While Rin, along with his classmates, were staying at his dorm for a week to study for the Exwire authorization exams, Rin couldn't help but notice that Izumo Kamiki was treating Shiemi as her servant, which began to worry him.
Confronted Shiemi about it, Shiemi dismissed that notion, exclaiming that she was helping a friend. However, they stopped arguing when they heard Izumo and her friend Noriko Paku's screams coming from the girl's room, and Rin told Shiemi to go bring Yukio as he rushed to their help. After Rin saved Izumo from her two Byakko familiars who were about to attack her for sensing her fear, he fought against the Naberius who snuck into the dorm, while Shiemi came to treat Noriko's wounds. Since Rin couldn't risk unsheathing Kurikara and exposing his true form in front of his peers, the Naberius easily pinned Rin down and started to strangle him. Thankfully, Yukio arrived in time and shot at the Naberius, forcing it to retreat. After that, when Rin noticed a crying Izumo blaming herself for not being able to do anything to help Noriko, he gave her his shirt, telling her to go change.
Next morning, Izumo came to Rin to give back his shirt and threatened him not to tell anyone for seeing her crying, as well as thanking him for saving her. Later, while Rin and his classmates received the Baryon punishment for having a vicious quarrel in the classroom, Yukio lectured them that no Exorcist should ever fight alone. Shortly after Yukio left for a mission, a blackout occurred at their dorm and the same Naberius appeared again. After Shiemi had her Greenman familiar, Nii-chan, provide a tree barricade to prevent the Naberius from getting closer, Rin volunteered to lure the demon away from his classmates while they make a run for it.
However, the Naberius spilt itself into two bodies and had one chase after Rin while the other stayed behind to try to bypass Shiemi’s wooden defense. Rin ran to the dorm’s power control room to turn the lights back on, but the Naberius threw him back away from the controls. When Rin exposed his blue flames, one of the Academy’s teachers, Igor Neuhaus, appeared from the shadows. Igor revealed that he was responsible for the attacks on his dorm, so he could confirm that Rin was Satan’s son. Angered by his actions, Rin unsheathed Kurikara and slew the Naberius with his flames, causing Igor to flee from the scene.
Training Camp arc
Shura confiscates Kurikara for the time being and summer break begins. The normal students leave but the Exwires take a three-day training camp. They set up camp where Rin enjoys his time with his friends. Yukio assigns them a solo mission to go after three lanterns in three days but warns that demons will come out at night. Shura also warns Rin not to let out his flames for it may be seeable at night. The mission begins where the group are attacked by demon moths. Ryūji, Konekomaru, and Renzō are able to protect themselves and Izumo uses her familiars. Shiemi plans to use Nii-chan for help but one of the moths rips her circle and Nii-chan disappears. That is when a large moth (probably its leader and guardian of the forest) appears in front of her. Rin hear Shiemi scream and goes after her, finding her injured due to the earlier attack from the large insect. When he sees her bleeding, Rin let his blue flames out, incinerating the moths. But the surviving sees they are Satan's flames and fly off to tell their boss. Rin calms himself down and tries to wake up Shiemi when Ryūji appears, asking what the blue light was. Rin's flames were very bright so it was hard for Ryūji to see. Renzō appears, letting out his fear of bugs when the two get a text message from Konekomaru that he found a lantern. They go to the depths of the forest together and find out that it's a Peg Lantern, a type of demon that wakes up when lit and likes to consume people into its fire, especially women.
Since it was large, the group realized that the mission required cooperation. Konekomaru devises a plan involving the five with Rin pulling the lantern, Shiemi feeding it so its flame won't go out, and the three Aria deflecting themselves from the moths. Rin stops, where the group is in front of a bug swamp with a broken bridge. Ryūji has an idea to have the Peg Lantern cross the swamp. Rin carries Shiemi and Ryūji awakes the Lantern. Seeing Shiemi, it goes after her. When it crosses, Renzō and Konekomaru at the other side seals the demon. Everything went okay until Rin is attacked by the giant moth. Rin tells them to leave, but Ryūji saves him by sealing the moth. They run off with the Peg Lantern as Ryūji tells Rin he helped as Rin helped Ryūji get over his embarrassment of saying he'll defeat Satan. He, Renzō, Konekomaru, and Shiemi tell Rin that they are his allies and will be there for him. Rin is glad but starts to think what happens if they find out that he's the son of Satan.
The group arrives to find Takara and Izumo had already finished their part of the mission. Then, Amaimon appears and unleashes his pet Hobgoblin, Behemoth. Seeing the students in danger, Shura protects the area with a magic circle and dumps holy water on them (except Rin). Shura suggests that Rin should fight Amaimon and gives him Kurikara. Rin is unsure about the choice when Shiemi suddenly walks out of the circle. There is a bug inside Shiemi controlling her and Amaimon kidnaps her. Rin goes after her and Ryūji, Renzō, and Konekomaru follow with flares. Amaimon tries to provoke Rin into using his sword by making Shiemi his bride or threatening to pluck out her eyes. The three monks-in-training intervene where Konekomaru accidentally puffs up Amaimon's hornlike hair. This provokes Amaimon by hitting Renzō and breaking Konekomaru's arm. He strangles Ryūji who tells Rin why he is acting weird and goes off on his own. Seeing his allies in danger, Rin decides to uses his flames as an act of kindness and fights Amaimon. They go into a heated battle where Yukio find the group injured and head them out of the forest to safety. Meanwhile, Mephisto watches. Rin's flames start to increase as he fights Amaimon. He is about to slice him, but Amaimon stops the blade.
He recognizes that Rin's flames are as powerful as Satan's, their father. Then, Rin lets out a roar of flames that instantly defeat Amaimon. Mephisto claps, seeing that Amaimon has done well and was surprised that Rin is able to defeat him at this level. Then he imprisons Amaimon into a large cuckoo clock only for Rin to slice and destroy it. Mephisto is startled by this. Rin's flames are increasing and consuming him as Rin becomes more violent and beast-like. Mephisto vanishes the clock with Amaimon and subdues Rin by sheathing Kurikara. At this point, the Paladin Arthur Auguste Angel arrives and confronts Mephisto and Shura about hiding the existence of Rin. Rin is taken into custody and taken before the Grigori.
In the anime, the cuckoo clock imprisoning Amaimon was cut in half by Rin, surprising Mephisto and releasing Amaimon, who escaped into the forest. The cracks at the base of Kurikara started to break down and could no longer substain Rin's power and he went berserk, starting a forest fire. His sword rebounded and hit him with a blast toward his classmates. Rin got up, not recognizing his classmates as his allies and Shura and Yukio were forced to fight him. However, Shiemi ran and embraced Rin, in which he recognized her and powered down. Due to his fight with Amaimon, he fainted from exhaustion. He was captured by the new Paladin, Arthur Auguste Angel, for a disciplinary hearing against Mephisto.
Mephisto Trial arc
In the manga, Rin is taken before the Grigori and pinned to the floor by Angel’s sword through his ankle. Mephisto, who is on trial, gives a speech inviting the Grigori to make a bet on Rin’s existence as a weapon against Satan. Rin infuriated by how they are all talking like he is a weapon and not a person burst into flame. He yells, "I am not a weapon! I am Rin Okumura and I will be the best exorcist you will ever see." The Grigori decide to agree to Mephisto's bet to a degree and decree that Rin must pass the exorcist exams in 6 months. He will be executed if he fails to do so or loses control of himself. He is put under constant supervision of Shura and Yukio.
In the anime, the Grigori imprison Rin in a large crystal and Mephisto is questioned for his betrayal. Mephisto states he intends to make Rin a weapon for the Vatican against Satan.
The hearing is interrupted by a earthquake by Amaimon, still alive, but wanting to fight Rin once more. Shura and Angel hold him off but are defeated. Amaimon reaches the hearing and grabs a hold of Rin. Soon, his classmates and Yukio (who were fixing Kurikara) arrive and gives the Demon-Slaying Sword to Rin. His demon heart beating within the sword, Rin awakens and quickly slays Amaimon's vessel. Again, he collapses but is able to beat the demon. The Grigori decide Rin will be spared but must pass the Exorcist exam or be executed. Same goes if his flames goes out of control again.
Filler arc (Anime Only)
Regaining possession of Kurikara, Rin sees his classmates where Konekomaru fears him because of his heritage. A pipe collapses releasing Coal Tar and attacking Shiemi. Rin saves Shiemi using his flames which do not harm her. But Bon does not want Rin to use his flames as Satan's fire killed powerful exorcists during the Blue Night including Bon and Shima's family and Konekomaru's parents. Rin is taken by Yukio for special training by Shura. Shura decides Rin should control and manipulate his flames by lighting two candles, explaining Rin was easily consumed for he is afraid of his power. Rin practices but fails, accidentally burning Yukio and Shura's clothes off, but not noticing an unusual mark on Yukio when Yukio puts on his coat. The next day, Rin continues trying to manipulate his fires when Izumo arrives. She explains Rin's situation as it happened to her with her familiars and encourages Rin, saying there are others like him related to demon by blood who are also exorcist. Soon, they are confronted by a dark demon. The demon, late revealed to be named Gale, attacks them. It shoots Rin with knife-like feathers and tackles him through the door. Just as it is about to try and finish him off, Yukio arrives and shoots it, forcing it to release Rin and flee out the window. Later, after Rin and Izumo finish cleaning up after the attack, Mephisto comes and explains the situation. While the others are assigned to check the barriers, Rin is forced to stay put and continue with his candle training. Frustrated with his lack of success, Rin tries to convince Yukio to have them both go out and search for Gale. Yukio refuses and angrily reminds Rin that he has little time to be goofing around as the Exorcist exam draws near. Yukio, after experiencing a quick moment of pain, excuses himself to use the restroom, leaving Rin alone. Rin uses this opportunity to try and sneak out to hunt for Gale, but is interrupted when someone enters the class. Rin falls from the window he is attempting to climb, denying that he was trying to escape. He stops this, however, when he realizes it is only Konekomaru. He begins to tell Konekomaru not to scare him like that, only to stop when he sees Gale on Konekomaru's shoulder. Off-screen, he draws his sword and tries to attack Gale. However, this is mistaken as an unprovoked attack on Konekomaru by Bon, Shima, and Yukio, as it seems they cannot see Gale. Rin tries to slash Gale, only to be stopped by Bon using Shima's staff, and Yukio aiming a gun at him. When Rin tries to point out Gale to them all, he realizes that Gale isn't there. They all lower their weapons, but Rin sees Gale on Konekomaru again and tries to blast it with fire. Fortunately, Bon manages to tackle Konekomaru and saves him from being burned, at the small cost of getting the back of his shirt burned. When Rin tries to see if Konekomaru is alright, Yukio pushes him to the wall and yells at him to ask what he was thinking. Bon then punches Rin in the face and tells him that he warned him that he would not forgive Rin if he hurt any of his friends. Rin withdrew his sword and leaves with his head hung. Later, he is lying on a rooftop, thinking about the day, when he is attacked by Konekomaru, who has been possessed by Gale. Konekomaru knocks him off the roof and creates a wind barrier to prevent Bon, Shima, and Yukio from interfering. As Konekomaru tries to kill Rin, Bon yells at him to stop, as he is turning into a demon himself. Gale loses a bit of his hold on Konekomaru, who hears what Bon is saying. Rin, who was in Konekomaru/Gales' claw at the time, covers himself with flames, forcing Konekomaru to release him. He tells him that he's not the son of Satan because he wants to be, and that if Konekomaru is scared, he should go to any of his friends for help.
Realizing what he is doing is wrong, Konekomaru begins to fall from Gale. Gale, realizing that its' host is rejecting it and not wanting to lose Konekomaru, begins to take off. Rin draws his sword and tells Konekomaru to trust him and jump. Konekomaru does; and Rin jumps, catches him, destroys Gale with a single slice from his sword, and collapses back on the ground. Yukio asks if he's alright while Rin sheaths his sword, and Konekomaru tearfully apologizes for what he has done.
The next day, as Konekomaru stands on a train platform, Rin comes up behind him and gets his attention by hitting him in the back of his knee with his own. When Konekomaru turns, asking who they were and why they were doing this, realizes that it is Rin. Rin asks what he is doing there, and Konekomaru explains that he is leaving cram school, as he will only be a danger to himself and others if he stays. Rin manages to convince him not to leave, then yells at the others when they 'interrupt the moment'. He is then forced to carry Konekomaru's bag for him because, as Izumo says, 'that's what friends do isn't it?'.
On Izumo's birthday surprise planning, he and Konekomaru are put on cake duty. When Izumo sees them in the library, Rin jumps out the window, leaving a panicking Konekomaru and telling him that he leaves the rest with him. Later on, he and Konekomaru start creating a cake for Izumo which Konekomaru finds it awkward for he tried to kill Rin while possessed by Gale. However, he sees Rin is not a bad guy and helps him with the cake.
Eventually, Izumo finds out but the party is decided to be about everyone's birthday and friendship. Rin and Konekomaru successfully make a cake for everyone. Rin accidentally pushes it over but Konekomaru catches it which Rin thanks for. Rin is the first for a raffle which he gets a bunny and Yukio gets Grocho glasses (which Rin states fits perfectly). However, their happiness is cut short when Yukio gets a call that the monastery they lived him was attacked.
Yukio and Rin ran to the monastery to find it covered in demonic webs and their priest friends covered in a hard cocoon, only having several hours to live. A sign was left in Polish saying "I've never forgive anyone related to Satan" which means Rin. Angry that the priests who took care of him were attacked because of him, Rin runs off to find the one who's causing it. In an alley, Rin is attacked by a masked man who attacked the monastery. Before Rin could use his sword, the masked man covers it in web. The masked man wants Rin to suffer when attacked by Yukio and Shura which the masked man escapes.
Back at the monastery, Rin cannot unsheathe the sword due to the web and Yukio rallies up the instructors to find the masked man which he suspects is Igor Neuhus. Rin wants to go after him but Yukio does not, saying he wants to protect his brother from the dangers he could face. Rin runs up but shot by Yukio with a tranquilizing dart. Rin loses consciousness as Yukio leaves the building.
Soon, Rin wakes up who is upset at Yukio and wondering why he's so frantic at protecting him. Rin takes his sword but taked by Shura. Shura tells Rin that he still cannot control his flames and it causes trouble for everyone. She has him proceed to candle training, explaining the candles represent people he is close to the most. Shura explains that if Rin has proper control of his flames, people wouldn't be afraid or worried of him and gain their trust. She gives Rin one chance which Rin concentrates on willpower.
Meanwhile, the masked man has Shima, Suguro, and Konekomaru as hostages and Yukio goes after him. He takes Shima's cell phone and calls Rin, stating he will kill him unless the son of Satan shows up. Yukio intervenes but the masked man traps him in a web and since the deal was broken, the masked man decides to kill the monks and use Yukio as a hostage. Rin and Shura show up which the masked man wraps up Shura and the other Exorcists who try to intervene. Rin dodges the attacks and ignites in blue flame, which burn up the web on the sword. Realizing this, Shura tells Rin to use his flames but Yukio protests. However, Rin listens to Shura and lets out blue flames. Rin's flames do not hurt everyone but burn the webs trapping them to people's surprise. Rin has control over his flames as they are his own power and not Satan's and he shouldn't be consumed by them. Rin unsheathes the sword as the masked man attacked. With one swing, Rin knocks the masked man out the window. Shura goes after the masked man and Rin follows but finds Yukio frustrated as his failure of protecting Rin from all this. Rin goes outside to find the masked man escaped and Shura has Neuchus captured which he claims the masked man is his wife.
Back at the monastery, Rin is able to free his friends with proper control of his power. Nagatomo tells that Rin has grown up and if only Shiro Fujimoto was there to see it. Then Maruta questions where Yukio went off which Rin questions too. The next day, Rin and Tsubaki visit the interrogation of Igor Neuhaus with Shura. They discover the masked man is his wife, Michelle, but Rin was told by him that she and his family died. Neuhus explains that he preserved her body in the artificial lab but her corpse was revived and possessed by a demon. The exorcists burnt the lab and attempt to execute Michelle but Neuhus takes her away and they go rogue. However, Michelle recalls her memories of being burnt alive by Satan's flames and goes after Rin to make him and Satan suffer when she had. Neuhaus explains that she won't live as long being a corpse as she will eventually rot. Rin decides to go after Michelle which Shura gives him a seal where her familiar will track her.
While Rin tries to figure out the seal, he gets a call from Shiemi for help. He visits the Exorcism Supply Shop and follows Shiemi's familiar Nee, who leads him to her grandmother's room in a hidden door. The seal glows which the familiar tracks Michelle nearby.
Rin unsheathes his sword seeing that Shiemi found Michelle and aided her in her grandmother's secret garden. Michelle grabs Shiemi and threatens to Rin that she'll kill her and make him suffer. However, she collapses from her injures. Rin tells Shiemi that Michelle is dead and responsible for trying to kill their classmates. Shiemi objects and does not want Rin to hurt her for the Greenman in the garden sense good inside her. Rin sheathes his sword and goes outside to call Shura of Michelle's location. When he makes a phone call, he is confronted by a group of exorcists led by Angel.
Angel beats Rin into the dirt and has Michelle and Shiemi cative. Angel is sent to destroy Michelle until Shura and Neuhaus come in to save her. Rin unleashes his demonic power to fight Angel and defend Michelle to her surprise since she tried to kill his family and friends. An unknown shooter triggers a gun to shoot Rin, but Michelle takes the attack for him. Rin, furious, demands which of the group shot her. Igor carries Michelle, who wishes they live in peace in the Amahara garden. They prepare to leave but Angel orders his team to shoot them. The Greenman help by shielding the couple in a vinelike barrier, possibly aidding them in their escape. The bell rings which is a emergency call from the Vacitian. Shura, Angel, and the other exorcists retreat to the Grigori as Rin and Shiemi look onward the vine barrier that Greeman created.
Ernst Frederik Egin (who is the father of Yuri and grandfather of Rin and Yukio) takes over as pope and leader of the Vatican. He reveals his objective to slaughter all the demons using specialized weapons from his lab that suck the blood of demons defeated by this weapon. He appoints Yukio as head of the Japanese Branch and the new Paladin to Rin's shock and dismay.
Yukio orders everyone to slaughter the demons in different regions which both the Exorcists and Exwires attend to. In a camp in a different part of the woods, Rin takes Kuro along and watches Coal Tar burn to death. The Exwires have different thoughts including Shiemi if this is the right thing to do. Suddenly, a demon boar attacks the grounds which Yukio arrives and shots the demon. However, Rin realizes (by demon telepathy) that the giant boar was the king of this forest and angered that the Exorcists killed its kin. He tries to explain to Yukio, which Yukio states that every demon on Earth must die. Rin is shocked and asks if Yukio wants to kill Kuro, Ukobach, or Izumo's familiars. Yukio responds by pointing a gun at Kuro. Rin combusts into flame to stop Yukio, stating that Exorcists are not murderers. Unknown to him, Yukio grows claws and slashes at Rin, knocking him unconscious. He orders one of the Exorcists to take Rin to a prison within the Vatican.
Rin wakes up, imprisoned and meets Mephisto who is also arrested. Mephisto explains that he was in charge of the artificial life lab and Neuhaus was one of his students. Rin realizes that someone brought Michelle to life that way Mephisto would be arrested. Hearing about the situation, Mephisto turns into dog form and escapes with the hamster Amaimon, leaving Rin behind.
Ernest with other Exorcists find Mephisto escaped and assigns Angel to be on the lookout. He encounters Rin and states how Rin looks very much like Yuri.
At sunset, Rin is sentenced to be executed at the top of the True Cross Academy. He is strapped in the center with columns of blood-sucking weaponry used surrounding him. The exorcists chant a hymn where Ernst takes out Kurikara, opens it, and releases Rin's demon form. He stabs Kurikara into the center which reacts with the circle and weaponry and causing Rin great pain. Yukio arrives too late who finds out that Ernst is using Rin as a sacrifice to open Gehenna Gate (Rin didn't know Yukio agreed to Ernst's plan so he and Rin can become human but was lying).
Hearing Rin's execution, Shiemi, Suguro, Tsubaki and the rest of the Exwires arrive to the top only to discover the Exorcists and Rin unconscious and a portal to Gehenna opened. Ernst's true objective is revealed as we see Yukio in demonic form and consumed in blue flame.
Kyoto Mission arc
This arc is exclusive to the manga and does not occur in the anime. After the trial Rin begins to take special lessons taught by Shura. Shura tells him that before any training with swords can be done, Rin must first master his flames. His first test is to light the wicks of two candles simultaneously while not lighting the candle between them. Rin has little luck with the exercise as he is only able to project large amounts of flame, which destroy the candles, as well as Yukio's (who was observing) and Shura's clothing. Yukio is then called to a situation in the city. Shura and Rin leave with him.
Shura, Yukio, and Rin arrive at a taped off section of the city. There is a demon on the loose that has stolen the left eye of the Impure King from the academy, as well as taken a child hostage. Saburota Todou, an upper second class exorcist in charge, tells the trio that a miasma (demon poison) is spreading from the scene, infecting civilians with fatal boils. While they are talking, the mother of the kidnapped child arrives and asks them how her son is. Rin reassures her that the child will be saved no matter what, to which Yukio intervenes and says that there is no definite guarentee that he can be saved. Rin confronts Yukio, asking why he would say such a thing. Yukio snaps at him, saying that Exorcists are not omnipotent and cannot always save everyone, and that Rin shouldn't promise that they can save him. In reply, Rin tells him that Yukio should not decide if he can be saved or not before an attempt is even made.
Yukio, Saburota, and two other exorcists put on hazardous material suits and enters the miasma-filled area, telling Rin to stay out. Rin disobeys and enters, seemingly unaffected by the miasma. They find the demon (who is hidden behind a breathing mask and cloak) and the infected child. They confront the demon only to have it disappear and they find the eye it carried is a fake. Suddenly, Yukio is attacked from behind by Saburota, who reveals that he is possessed by a demon and has stolen the real eye. Rin tries to take the child outside the area but accidently burns him when he tries to block one of Saburota's attakcs. There is a brief fight after which Saburota disappears taking the eye with him, not before telling Yukio that he reminds Saburota of a younger version of himself- both males were assigned to become exorcists by their families, unable to live the lives that they wanted to have. He then tells Yukio that everyone has weakness in their hearts, questioning if Yukio would ever succumb to his weakness and become possessed. After Saburota leaves, Yukio then attempts to save the badly poisoned child, but finds himself unable to concentrate because of his words. Stabbing himself with a needle, Yukio is able to concentrate and save the child. Impressed and somewhat humbled by Yukio’s abilities Rin swears to God that he will surpass Yukio, to which Yukio replies with a smile that he shouldn't go around saying that to everyone and that he will not be able to take care of his older brother forever.
Rin is later seen training privately on top of his roof, becoming frusterated at his ability to properly focus and burn only the two candles. Shura comes up, suprising him with her knowledge that she knew he was secretly training every morning. She then throws him a travel guide, informing him that he is going to Kyoto on a mission and that he better prepare himself. While waiting for the train, Rin is reading the travel guide peacefully while Shura, seated in front of him, complains to Yukio that she is in charge of the Reinforcement Squad for the Right Eye. Yukio tells her to take care of Rin, to which Shura replies that he is being too serious again.
Boarding the train, Rin tells Shura how he didn't go to Kyoto for his middle-school trip and that this is his first time, asking her if they should take bananas as snacks. She asks if he is going to keep up this child-like attitude until he has enough fun, to which Rin says that he is excited because it is his first time leaving Academy City. Once they are on the train, Rin asks Shura where he should sit, to which Shura replies that, judging from the looks on the other exorcist's faces, he should sit away from everyone else. He then says hello to Shiemi, who just walked on, who replies with a frightened hello before walking away. Seeing Bon, Shima, and Konekomaru, Rin says hello and asks them if there is anywhere they'd recommend he visit while in Kyoto. The three walk down the aisle without saying anything to Rin while discussing how they are suprised that Rin is still alive, saying that he could go on a rampage at any second. Depressed, he thinks how it is only natural that everyone would be afraid of him after witnessing his fight with Amaimon. Izumo walks in, turns down Shima's invitation to sit with him, and slides into the seat next to Rin, much to his suprise.
Shura then informs the group about their mission- to reinforce the weakened guard in Kyoto, where the Right Eye of the Impure King resides. Izumo aks the group of exorcists what the Eyes are. The eyes belong to the Impure King, a demon who released diseases and epidemics in the Ansei Era (1854-1860), as well as caused the deaths of around 40,000 people. Although the monk Fukaku killed the demon and removed the eyes, someone is trying to steal them and do evil things with them. Shura finishes by saying that their specific duty is to nurse the injured exorcists who were attacked by someone trying to steal the Right Eye, as well as reinforcing their guard.
When Shura finishes, Rin turns to Izumo and asks her if she is afraid of him. She says that she isn't because many people and exoricts around the world are related to demons by blood. Shocked, Rin listens as Izumo says that the reason why so many are afraid of him is that he is the son of Satan, and that no one knows if he will become a boon or bane to the Order. Nevertheless, no one should be making such a big deal out of his heritage. Rin , touched by her words, calls her "Eyebrows" affectionately, and says that he always knew she was a good girl. In reply, Izumo yells at him, asking how he came to that conclusion and why he calls her "Eyebrows." Rin just thanks her, while Izumo replies that it isn't anything, she just hates cowards who run away from friends at crucial times, like Bon and Shiemi. Angered, Bon calls her a bitch, causing all of the Exwires to be punished.
While the group are being punished, Konekomaru asks why Rin is being let out on a mission, saying that he is dangerous. Suddenly, the rock demon on him flies off and lands on Shiemi, pinning her to the floor. The group tries to remove it but are unable to because the particular rock demon used to punish them can only be destroyed by high amounts of heat. Rin tells everyone to move aside and walks up to the rock and tries to lift it, but he is unable to. He then sets his body on fire, scaring everyone except himself and Shiemi, who says that the flames are not hot but warm. Bon tries to grab Rin to push him away from her, but ends up grabbing the flames and throws it into the cabin, spreading the fire around. Izumo summons her familiars to create holy wine to put out the fire. Meanwhile, Rin grabs Bon and asks him why he got in the way, saying that he had everything under control and that he should have faith in his abilities. Bon, extremely angered, asks how could he not try and force Rin away from Shiemi, saying that those blue flames can kill people. He goes onto explain that, during the Blue Night, his grandfather, Shima's grandfather and eldest brother, and Konekomaru's father died because of those flames, and asks Rin how could he ever trust those flames. Rin says that the death of so many people close to them must have been horrible, but it has nothing to do with Rin. Konekomaru intervenes, saying that, as Bon intends to defeat Satan, he shouldn't do risky things on his own.
Shima then yells at Bon to watch out as a rock demon flies at his head, which is intercepted and sliced by Shura. She then yells at the group, saying how if they cannot take on small demons and can only hamper one another, how would they be able to fight real ones. As they exit the train station, Rin stares at the Kyoto Needle with a sad expression on his face. The group then arrives at the inn they are staying at, which turns out to be the inn Bon, Shima, and Konekomaru grew up in. After being introduced to the head of the inn, Bon's mother, the group heads over to help nurse those infected with miasma while the three Koyoto members go see their families. Rin goes to help out one of the head priests, who reveals himself to be the head priest of Fukaku's temple, Bon's father. The two discuss Bon, and, aftering Rin sees Shiemi, Bon's father slips away. Later, Rin walks into an argument between members of the Shima family and the Houjou family, stating that he thought Kyoto would be more elegant than he has seen it.
Rin continues to struggle during his training to control his flames but eventually was able to manipulate his flames at will once. Tensions rise when a traitor amongst the monks is discovered and Suguro demands answers from his father. Suguro argues with his dad which makes Rin remember how he told Shirō not to act "fatherly" before his death. Rin berates Suguro to apologize to his father. When Suguro refuses, Rin loses control of his flames exposing his parentage to the monks. Shura is forced to render him unconscious with an imprisonment spell. Rin is put in a prison where Shura gives him a letter from Suguro's father. The letter informs them and Yukio of how the sword Kurikara originally belonged to the monastery and that Shiro took it to kill kids (supposedly Rin and Yukio after they were born). He requests that Rin defeat the Impure King whose body is hidden in the temple as Rin's flames are capable of defeating him.
However when Rin tries to unsheathe the sword, he cannot. Shura realizes that Rin has lost his confidence because of his earlier loss of control. Mephisto arrives and announces that Rin has been sentenced to death. He then summons "the strongest prison" and puts Rin within it. Meanwhile, Saburota has revived the Impure King and Shura fearing they will be unable to defeat him sends the Exwires to free Rin. Inside the prison, Rin wonders if he should have been dead and why Shiro let him live.
Shiemi manages to get into the prison to save Rin. Fearing for her safety, Rin tells her to leave him alone believing he will hurt her. Shiemi refuses when Rin tries to scare her off by igniting his blue flames. Shiemi, realizing how foolish she was, hugs Rin, restoring their friendship. Shiemi gives Rin encouragement to break out of the prison and he is surprised to find all his friends by his side. At this point Rin reconciles with Konekomaru and the others. Suguro tells Rin he will lead him to fight the Impure King as all the monks and exorcists gather for the battle.
Rin and his friends proceed to the battlefield and are horrified at the scope of the Impure King. They contact Shura and are asked to find High Priest Tatsuma, Suguro's father, who has gone missing. They find him collapsed in the forest badly injured. On approaching him the demon Karura appears and declares that it is fulfilling a personal contract to Tatsuma. Tatsuma regains consciousness and tells Rin how to defeat the Impure King. The Impure King will continue to grow and will eventually grow a sporangium that will release a toxic miasma. The weak spot of the Impure King, its core, lies within the sporangium. This core is the combined eyes of the Impure King. Tatsuma explains how he attempted to use a technique called Gouhaen with Karura, which converted his life into flames to stop the Impure King but was unsuccessful. He then tells the group that he will use his remaining life to hold back the miasma should it be released. During this time Rin should destroy the core. Bon objects and Karura's contract is switched to Bon by relation of blood, so that Tatsuma may live. Tatsuma teaches Bon what he must know and collapses. Shima and Konekomaru leave to go tell Shura and the exorcists what has happened. Izumo and Shiemi stay behind with Tatsuma. Bon says he will but up the barrier but he must get close to the sporangium. Rin declares that he will protect Bon and the two head towards the Impure King.
Rin and Bon get close to the Impure King and see that it is starting to take on the shape of a building. Bon urges them to hurry and Kuro comes out of the Forest. He warns Rin that it is dangerous and tells him to run away. Rin refuses so Kuro transforms to his bigger form and tells Rin he will come with him. Rin and Bon climb onto Kuro to get a ride. Kuro gets them as close to the Impure King as possible and they land on a rock so that Bon can put up a firey shield that manages to contain the Impure King and keep the poison contained for the time being. Rin and Kuro fight to protect Bon from the Impure King while he is in physical contact with the earth but Rin still can't manage to draw his blade. As the fight continues things start to look really bad as the sporangium finally erupts and the Impure King finally shows his true form.
The Impure King then targets Bon but Karura manages to protect Bon by shielding him in a cyclone of hot wind and flames. It works and drives the Impure King away from Bon but this line of defense weakens Bon twice as fast and the shield will only last for 15 more minutes before Bon runs out of strength and it dissapears and thus unleashes the Impure King completely. Rin tries to draw his sword but even with the situation getting worse by the second he still cannot draw his blade. Bon tells Rin to run while he still can and get to safety. Rin then says that he wants to visit the Kyoto Tower and that Bon can show him tomorrow, that's why Rin wants everyone to be safe, so that they can go visit it. Bon then asks why he would want to go there in the first place (he himself has never been there as he finds it embarrassing) when Kyoto has much better tourist attractions, to which Rin replies that he's wanted to visit the tower ever since he saw it and because he doesn't know that much about temples and would prefer to see some of the fashion spots. Bon then laughs and says that he'll support Rin's fake confidence because they're friends and because he trusts Rin.
Rin, after hearing this, asks himself why Shiro saved him, why was he saved. Finally, Rin was able to draw the Kurikara and begins to fight the Impure King with his flames proving to be very effective. Shura shows up and says that she'll protect Bon while Rin faces off to fight the Impure King, telling him to prove to her that Shiro was right in letting him live. Bon soon runs out of energy to maintain the protection, and the fire shield that had contained the Impure King vanishes, and the sickness-inducing miasma begins to spread down the mountain towards the city. Rin is desperately trying with all his might to cut and burn down the Impure King before it reaches the city when, from out of his sword, comes the sworn enemy of the Impure King, Ucchusma.
With this new power, Ucchusma then tells Rin how to control his flames and how to use them to efeat the Impure King by summoning Kashou Zanmai which will burn everything in the material world and allow for Rin to purify everything on the mountain. Rin is hesistant, and protests against using such power because he does not wish to harm all the people fighting on the mountain as well. Ucchusma shows no concern for any of their fates, and displays only an uncaring apathy towards the other Exorcists' wellbeing when he retorts that there is no time to be thinking about such trivial things and that everything and everyone continated by the Impure King must be purified now. Before Rin has much time to think on this, the Impure King nearly hits him with one of its attacks; he is still not sure whether he can defeat the enemy without hurting anyone, but decides to try and then starts the chant as the words come straight to him in his head. He finishes the chant with Ucchusma's encouragement, and releases a massive fireball at the Impure King's body mass only to find it is still not enough. The fire demon demends why Rin is not putting more power into his flames; but Rin mentally states to himself that if he puts any more power into the flames, he'll be burned out, and the flames would consume him.
Still, with one more effort, he shoves more power into the flames. Rin then begins to slowly slip out of control as his own flames begin to overwhelm him, and rip his self-restraint apart. With his control almost gone out of his reach, the son of Satan snarls to himself that his power has been repressed since his birth and that he has had to put up with that! He cries out for it to stop while thinking to himself that he has had enough; his power and himself is now free, and he will rip everything to pieces, a beast that burns everything to ash.
But, placed on the every edge of losing his grip on his humanity, Rin suddenly remembers what Shiemi had said to him when she appeared in the jail; "I'm not afraid." She was completely unharmed by his flames and it was because Rin himself made it so. He recalls all of his friends and how they all put their faith in him, how they trusted him, and he decides he wants to live up to their faith and expectations. Confident once more and no longer struggling for control, Rin, armed with this new relevation, calmly unleashes as much power as he can on the Impure King's monsterous form. He succeeds in completely scorching the Impure King from Assiah with a blinding explosion of light, and sending waves of brilliant, bright blue flames down the mountain, burning everything that had been contaminated and destroyng all of the bacteria. The flames do not burn away anything BUT the Impure King, and everything on the mountain is purified of the sickness. However, nobody on the Exorcists' side is harmed or burned by the flames as all; Shima even describes the flames as being warm to the touch, yet not painful at all.
Rin staying alone by himself on the mountainside in the dawn's light, looks onto the mountain, now completely cleansed of the Impure King's taint, and with the repulsive, massive monsterous creature itself defeated. Ucchusma appears before Rin once again, flatly stating everything has been purified, and he's leaving now. He then wonders aloud whether Rin is a human, or a demon and disappears from Assiah with one final parting remark to the son of Satan on regards to which one he is; "One day, you will have to decide."
Powers & Abilities
Since childhood, Rin has been physically stronger than most normal people his age, even people several years older, most likely because of his demon heritage.
It is shown that he can easily lift a car, metal rollercoaster debris, and both his and Shura's backpacks which Shima ironically called demonic strength. As a young child he was even able to punch hard enough to bend metal, break glass, throw a chest full of toy as well as desks and chairs across a room, and with one punch break three of Shiro's ribs.
Because of his possession of Kurikara, he aims of becoming a Knight, a type of Exorcist who uses swords and other blades in combat. While he trains to get better in his swordsmanship, he mostly relies on his superhuman strength and blue flames in battle.
Rin wasn't a tamer because he doesn't summon demons.
Partial Demon Form
Rin can tap into the power he has inherited from Satan through Kurikara, a blade that was used to seal his powers when he was born. The sheath also acts as a portal to Gehenna, the demon world, which when drawn, returns Rin to his demon form. In both his human and demon form, Rin can release incredibly destructive blue flames, which are the trademark of Satan. However, when he draws Kurikara, the magnitude of the flames drastically increases, as well as a decrease in Rin's control over them. Amaimon has stated in his second fight with Rin, that his powers are like Satan's. When Rin releases the blade, the greater magnitude of flames often leads to Rin being "consumed" by them, resulting in a berserker rage where he lose control and goes on a rampage, attacking everyone around him. However, Rin has been shown to stop himself in this form, but only with great difficulty. Before going to to fight the Impure King he is shown trying to draw Kurikara however this fails due to his lack of confidence in controlling his powers.
Rin has been shown to be able to use his sword and manipulate his blue flames through emotions, as he was seen saving Shiemi from falling debris by making a claw out of his blue flames. He can also release intense blue flames out of his sword when its swung with great power. Rin is currently learning how to manipulate the flames at will, allowing greater control and to prevent being consumed by its power. In the anime, Rin was able to control his flames properly, which he used to burn the webbings that trapped his fellow Exorcists including Yukio, Shura, and Suguro from the avengeful masked man. When Yukio awakened to his demonic nature, he and RIn combined their power which forms into a large phoenix out of blue flames. Using this form, the brothers were able to fly into the air and destroy a huge Gehenna Gate that was attacking the city (which was also created combining Rin and Yukio's blood). Rin is imprevious to Satan's blue flames.
In addition, through his demon powers, his body has shown to have high-speed regenerative abilities. Rin has mentioned that as a child, he always healed very quickly, which he had initially thought was due to his brother Yukio's skills at bandaging him up. His healing rate is so fast that, after getting stabbed in the stomach, he lifted up his shirt only seconds after and showed Yukio that the wound was already closing itself up. He is also immune to the effects of miasma or other energy-draining substances created by demons that would otherwise cause great harm to normal humans.
Rin can communicate with demons that are incapable of human speech, such as he was able to hear Kuro's thoughts. In the anime, he also understood what Ukobach was saying.
Due to practicing from a early age, Rin is an amazing cook. He displayed this in a cook-battle against Ukobach and when baking a birthday cake for Izumo and when he made lunchboxes for him and Yukio.
