BonRin

BonRin is the slash ship between Ryuji Suguro and Rin Okumura from the Blue Exorcist fandom.

Canon
Okumura Rin is one of the 2 half-demon children of Satan and inherited his blue flames, while Suguro "Bon" Ryuji is the child of the Head Priest from one of the many temples that was attacked on the Blue Night. Because of what happened on the Blue Night and Satan being the reason of the death of Rin's adoptive father, the 2 of them share the same goal of defeating Satan. They tend to quarrel a lot and initially didn't get along, but the 2 of them don't have a problem admitting they are friends by the time the anime ends. While Rin often compliments Bon even when the 2 weren't even friends yet. Bon tends to call him a moron but is often concerned for him. The relationship between the 2 of them goes through quite a lot of development during the show.

Anime
The anime adapts the manga quite closely until the training camp arc, the rest of Season 1 follows an anime-only arc. Season 2 goes back to closely adapting the manga, although it isn't completely the same (same goes for the first part of season 1).

Season 1
The 2 of them first meet when Rin joins the cram school. However they don't truly interact until Shiemi joins the class, outside of Bon commenting on how much of a pain Rin is when the other students are forced to stay outside so that Rin can talk to Yukio.

In episode 5 they truly start interacting. After Rin gets called out by their teacher for falling asleep, Bon asks himself why Rin is even here. When Rin turns to look back at him, Bon tells him to piss off. Rin recognizes that Bon's been glaring at him since the start and takes a good look at him. He notes how rebellious he looks and thinks Bon looks really cool. He mentally says that normally he'd glare back and call him out for a fight after school, but doesn't now that he's going to become an Exorcist. During the rest of the classes, Rin keeps falling asleep, furthering annoying Bon. When they get test results back with Rin's being very low, Bon says that he couldn't get a 2 even if he tried and that it's because he keeps fooling around with Shiemi and that Rin makes him sick. Rin gets annoyed and calls him a rooster-head and says that he's the one who's fooling around. Bon smugly shows off his test result, which is a 98. Rin asks how someone like Bon could have a 98 and Bon gets annoyed at this and says that he came to the cram school because he's serious about being and Exorcist and so is everyone else and that someone like Rin should just get lost. Rin replies that while he may not believe it, he's actually trying to become an Exorcist as well. They get pulled back by Shima, Miwa and Rin's twin brother Yukio, however they continue arguing. Bon says that he's never seen Rin pay attention in any of their classes, while Rin argues that he's an in-the-field kind of guy and that it's hard for him to memorize stuff while he's chained to a desk all day. Later after class, Rin is with Shiemi and Yukio and asks what's up with Bon and him being smart. Yukio talks about where Bon's from and that he's also on a scholarship. Rin replies that he's a rich little kid then, Yukio replies by saying he's an exceptional student, accomplished athlete and attentive students and that Rin should follow his example or maybe copy his whole mind. Rin replies that's going a little far. After Yukio leaves and Shiemi gets close to Rin to ask him something, Bon interrupts, while Miwa and Shima stand behind him. He comments on Shiemi and Rin's closeness again and asks if Shiemi is Rin's girlfriend. Rin denies and Bon keeps commenting on them, until Rin comments on how Miwa and Shima are always hanging around Bon and how sticking with your kind is lame. After Shima laughs and points out that Rin is right, Bon and Rin glare at each other and think the other pisses them off. Shima thinks that they seem to be the same type and Miwa thinks about how those who are similar repel each other.

During practical training, the 2 of them are paired together and they end up competing instead of trying to achieve the actual goal of the exorcise. Rin thinks about how he can't seem to lose Bon, while Bon thinks about how fast Rin is. Rin says that being smart is not going to help him in the real world, Bon takes a short cut and kicks Rin down while saying that in the real world the one who's left standing wins. However Bon nearly gets attack by the Reaper demon, but gets saved by the teacher. The teacher scolds them and Rin asks what that was all about. Bon says that he won't lose to Rin even if it killed him, Rin angrily asks what he thinks about dying right now. Bon accepts his challenge and they end up physically fighting, before quickly being pulled apart by the teacher and Bon's friends. Bon ends up being taken away to have a word with the teacher, leaving Rin with Miwa and Shima. Shima apologizes for his behavior and explains why he did what he did. Meanwhile Bon gets told that it's better that he won't cause any trouble but Bon asks why he's the only one getting scolded while Rin is just as guilty. The teacher says that Rin's a special case and got in the school with baggage. This annoys Bon. In the meantime Rin is still talking to Shima and Miwa. Shima ends up explaining that Bon wants to defeat Satan and Rin realizes with disdain that Bon's ambition the exact same as his. Shima misinterprets Rin's face as thinking that Bon's ambition is stupid and says: "See? Makes you laugh right?" Rin asks if that was supposed to be funny, confusing Shima. Miwa says that it's true and that Bon's so intense because he wants to restore their temple that fell into ruin because of the Blue Night. Miwa and Shima end up explaining what the Blue Night is and that it happened 16 years ago when many priests ended up dying because of Satan. Afterwards people were scared because so many priests died and ended up nicknaming the temple: "The Cursed Temple" and people stopped coming to the temple. After the teacher leaves after a phone call, the students are left alone with the still chained Reaper. Bon takes another jab at Rin's motivation and Rin says he needs to shut up and how he even knows that he's unmotivated. The 2 of them end up arguing again and Bon challenges Rin to touch the Reaper and return without getting attacked. He says he'll gladly acknowledge Rin's motivation if it works and that he'll try it too of course. Rin says he'll do it but immediately says afterwards: "Is that would you thought I'd say? Dumbass." Rin asks what would happen if he gets killed on accident. He also thinks about how he can't draw his sword in front of others. He then says he has the same ambition as Bon and that he won't risk his life over something petty like this. Bon turns to his friends, figuring out that they told Rin about his ambition. Bon says that Rin is just spooked, but Rin stays calm and says that Bon can say whatever he wants. Bon thinks about every last one of them keep making a fool out of him and thinks back on when he was a child when they talked about the temple behind his back and Bon decided he was going to defeat Satan. Bon yells back in the present: "Everyone one of you... Why don't you try to fight?! Aren't you bitter!" he then says he's going to do it and they can just stand there and watch. Rin yells after him to not do it. Bon walks towards the Reaper and yells about how he's going to defeat Satan. Izumo ends up making fun of him and Bon gets reminded of his childhood again. However the Reaper picks up on his emotions and goes to attack him. Rin immediately jumps in front of him to protect him. The Reaper ends up biting Rin instead, however he manages to stop the Reaper from attacking him by intimidating it. Rin asks if Bon is an idiot, while Bon is still surprised. Rin states that he's the one that's going to defeat Satan and that Bon should just stay the hell back. Bon ends up yelling at Rin and says that he's the moron because he could've gotten himself killed. He also tells him not to copy his ambition. Rin says that he never copied anything and that he's the original. The 2 end up arguing again. The day after, Rin is seen trying to study during break time and complains about how his hair gets in the way when trying to read. Bon walks up to his desk. Rin asks if he's there to mock him as well. Bon ends up thanking him for what happened while blushing. Bon gives Rin a hairclip he uses when studying at night and says he can borrow it, while still blushing. Rin says that this is creepy and that maybe it's a bad omen. Bon yells at him that he was being sincere. However Rin uses the hairclip often when he's in class or studying.

During lunch, Rin and Bon both end up grabbing the last bread, surprising Rin greatly. Rin says hi to Bon's friends, but Bon asks when he's going to let go. Rin and Bon end up arguing again. Bon says that grudges about food can last over 7 generations so they should settle this now to avoid that. However when Rin ends up learning Miwa's name he puts his arm around his shoulder, completely ignoring Bon. A few moments later, Bon asks when Rin and Miwa got so close. Rin gets pulled away from Yukio later. Another day, the Kyoto trio catch Rin crying over his lunch. Bon tells them not to look him in the eye because stupidity is contagious.

In class, when having the fill in their meister, Rin is unaware of what it means and goes to Bon and his friends. Bon berates him for not knowing something like that. Miwa explains it to him though. Bon ends up getting annoyed when Rin sits down. After hearing about Bon going for 2 meisters, Rin says: "That's our Bon." Bon says to not call him that. Eventually out of frustration, Bon ends up explaining it to Rin. Later, after Bon perfectly recites a passage, Rin says that Bon really is smart. Bon gets annoyed at this and asks what he means by 'really'. When Izumo and Bon start arguing, Bon slams his hand in front of Rin, who was reading, scaring him. They keep arguing and Rin eventually gets caught in the crossfire and tells them not to fight in front of him. A bit later, Bon tells Rin he's pathetic for not knowing what a Bariyon is. Rin argues that they wouldn't even be here if it wasn't for his fight with Izumo. When Bon asks if he and Yukio are really related, Rin replies that he's sure Yukio is a good guy.

When the ghoul attacks and Rin goes after it by himself, Bon is the first one to question him and try to stop him, however Rin has already gone away. Bon says after he's gone: "I-I don't believe that guy..." After Bon is nearly killed, Rin manages to turn on the lights, unknowingly buying Bon enough time to kill the ghoul. When Rin returns, everyone is surprised that he managed to kill the ghoul by himself. Bon ends up punching him and asks if he's got a death wish. Rin says he's the one who's trying to kill him now. Later Bon is being held back by Miwa and Shima from further attacking Rin, who's trying to placate Bon. After the Exwire exam, after being asked how he defeated the ghoul, Rin tries to deflect the question. Bon comments on how vague the answer is and that he thinks there is no bigger enigma than Rin. After Amaimon first shows up, the other Exwires not aware of him showing up, they see Rin being dragged away by Shura. Bon asks what Rin got himself into now. When Rin gets back to class after being interrogated by Shura, Bon notes that Rin seems different somehow. When the Exwires go on a training camp, Bon and Rin are setting up a tent together. Rin says it's looking more like a picnic now, however Bon says it looks more like a camping trip. He also tells Rin to stop hitting the tent but doesn't get to finish his sentence before the tent collapses, making Bon angry. After Rin makes dinner, Bon is surprised (like the others) and says the food is amazing. When the Exwires start preparing for the drill and Shura warns Rin, Bon asks where Rin's energy went and if he's chickening out, which Rin denies. After Rin went to help Shiemi and burst into flames to repeal the moths, Bon saw the blue light, although he didn't know it was from Rin. He asks if Shiemi is alright, who's unconscious. Rin confirms she's okay and Bon tells him to turn off the light, which is attracting the moths. When Bon asks about the light, Rin manages to deflect the question. Rin questions Bon about why he's here when he said no helping each other out. Bon tells him to shut up and that no one can ignore that scream. Rin tells Bon that he can go ahead and that he'll bring Shiemi back to camp. Bon goes to say something but is interrupted. When Bon has drawn out the plan while still reciting the verse, Rin excitedly compliments his drawing. After Rin is captured by the giant moth and told the others to run, Bon angrily replies that Rin is doing it again and that of course they'll help him. Bon ends up saving Rin and grabs him out of the swamp, they end up running when the moth tries to attack again. When the moth stops chasing them and the group stops for a break, Rin thanks Bon, but Bon says that he just paid back the debt he owed from Rin who saved his life and has the same ambition that he dared to say it out loud. Rin says he's just a moron so he doesn't think about those things too much, but Bon says that he doesn't think Rin is moron. However Bon says that trying to fix things by himself is a bad habit of Rin's and that he shouldn't forget that he has friends. After Amaimon attacks and Shura pours Holy Water on everyone except Rin, Bon asks if she's not going to do anything for Rin, Shura replies that he's allergic to Holy Water, surprising Bon. When Rin goes after Amaimon by himself, Bon calls out after him, but he's already gone. Bon thinks to himself that Rin is doing it again. After Amaimon attacks Rin, Bon gets extremely angry and goes outside the barrier protecting the Exwires. While being choked by Amaimon, Bon says that he's not interested in Amaimon and that the one he's super pissed at is Rin. He says that he thought Rin was selfish, but he looked out for others and that he was sure Rin had no special talent, but he's pulled off amazing feats. Bon asks what the hell is up with Rin. After Rin draws his sword, the Exwires are all surprised and Bon recognizes the sword he has drawn.

When the Exwires, minus Rin, are all gathered and Yukio explains about Rin's powers. Bon talks about the sword and eventually complies with Yukio's (and Shiemi's) request to look into the possibility of saving Rin. After they arrived at the temple to retrieve the nails needed to restore the sword, Bon and Yukio are attacked by a demon who takes advantage of one's doubts and uncertainties. The demon questions Bon's reason for trying to save Rin, but when Bon is snapped out of it, he says that his reason is that it would suck if Rin died before he could ask him why he would say something so twisted like when he said he was gonna kick Satan's ass despite being his son. When the Exwires arrive to bring Rin the repaired sword, Bon yells out to Rin and asks how long he's planning to sleep. When Angel goes to kill Rin after he defeated Amaimon, Bon is the one who calls out to Angel and asks what the hell he's doing. After Rin's back to class and uses his flames, Bon stops him and asks if he's trying to burn Shiemi alive. Rin gets confused and Bon elaborates and says that his flames can kill people. He also talks about the Kyoto trio's family members who had died because of Rin's father. He tells Rin that none of them have any plans of being friends with Rin, but if he ever hurts one of Bon's friends, he'll kill Rin without mercy. Rin says that he's not like Satan and to believe in him. Him and Bon stare each other down, but Yukio interrupts. Later, Miwa catches Bon studying late at night. When Bon explains his reasoning he says that he wants to win from Rin and Miwa says he's already above him since he's the top student, but Bon says he really realized during the last fray that it doesn't matter if you have knowledge if you can't use it in combat. When he's alone, Miwa says that Bon is really strong because even after seeing Rin go berserk, he still sees him as a rival. After Rin goes to attack the demon who's with Miwa, the others misinterpret it as trying to attack Miwa for no reason. When Rin warns Bon to step away from Miwa because he's dangerous. Bon responds by saying that he's the dangerous one here. Rin tries to attack the demon who appeared again, unknown by the others, but Bon stops him and asks what Rin is doing. The demon makes it's appearance again and Rin attacks with his flames but realizes too late that he'll get Miwa caught up in it too. Bon saves Miwa and punches Rin afterwards, telling him to remember what he said about killing Rin if he ever hurt his friends. Rin is confused why no one is commenting on the demon and yells at them. After Yukio confirms that Miwa is just unconscious, Bon repeats that Rin's flames can murder people and why Rin can't get that through his head. Rin goes away without saying anything. Later, when Miwa wakes up, he asks what Bon thinks of Rin. Bon says he has no opinion on Rin and that even after all the crap he pulled, he still has the nerve to tell him to believe in him. He also says that normally when you ask someone to believe in you, you have to have something more, but Rin has nothing. After Miwa admits that he's terrified of Rin, Bon says that Rin's nothing but a moron and his power may be terrifying, but he's got nothing going on inside of him and that it's ridiculous to scared of someone like him. After Miwa finds out that Bon's shirt is burned from Rin's flames, although only his shirt is ruined, he gives in to the demon. Meanwhile Rin is thinking back on Bon's words and berating himself. After Rin catches Miwa trying to leave the academy and everyone else shows up, Rin yells at them to not steal his spotlight. After Shiemi questions him, Bon tells them not look him in the eye, because stupidity's contagious. RIn asks who the hell he is calling stupid. When the prototype of Izumo's birthday cake gets presented to the other Exwires minus Izumo, Bon says it's all wrong since it looks like a Christmas cake. After the operation Jacob's Ladder goes into action and the Exwires are on a mission and currently eating, Rin goes up to them and asks what they're eating. Bon says it's their rationed meal and that he saved one for Rin as well before they ran out, Rin thanks him. After hearing Rin is to be executed, Bon angrily asks why, later when talking to Angel, he repeats the same thing. When the Exwires arrive to see what a mess Jacob's Ladder turned out to be with an open Gehenna gate and Rin on the ground unconscious, Bon takes Rin on his back and asks if he's okay the moment Rin stirs. After Satan goes to kill Rin, Bon interrupts and says to take him on first before he does anything with Rin. Later, Rin prepares to go after Satan to bring Yukio back and Bon says Rin is doing it again, going after people himself. When Miwa asks if he thinks Rin is okay, Bon says that he obviously is and that even if you killed him, Rin wouldn't die. After everything is over and Rin and Yukio are back with he other Exwires, Bon pulls Rin into an aggressive headlock and tells him not to worry them like that. He asks Rin what happened to Satan, Rin says that he must've headed to Gehenna, Bon replies with: "I see."

Season 2
Since the anime started producing an anime only arc, from about the moment Yukio explained about Rin's powers and the 2nd season does follow the manga for the Impure King arc, Rin and Bon's relationship doesn't have any of the development they got from the 16th episode onward in the 2nd season. So the first interaction they have is when Rin is sitting on the train to Kyoto and greets the Kyoto trio, Bon seems angry and looks like he's about to say something, but gets stopped by Miwa. When Izumo indirectly calls Bon a coward on purpose and the 2 of them start arguing, Rin decides to interject and says they're supposed to be teammates. This annoys Bon and Rin says for Bon to believe in him. Bon asks how he could believe in Rin. A flashback is shown of when Rin was taken away to the Vatican Headquarters after Amaimon attacked and Bon asks while yelling what Satan's spawn is doing at the cram school. Rin panics and says for Bon not to be such a drama queen. A bit later, a different flashback is shown of when Yukio explained Rin's powers, Bon asks what Shiro wanted from raising Rin. Back in the present, Bon talks about the Blue Night and how the people at the temple died in those blue flames. He says that those blue flames can kill people and explains about the Kyoto Trio family members who'd died that night and how he could ever believe in Rin after what happened to the people he cares about. Rin says that he's sorry that they had to go through that, but yells and says that it has nothing to do with him. Bon says that Rin said he was gonna defeat Satan. Rin confirms and tells him not to lump him in with him. Their quarrel gets interrupted by Shura who asks if they're gonna fight like that too during battle. After they arrive in Kyoto and meet Bon's mother, Rin is greatly surprised since he thought Bon's mother would look less feminine and delicate. He also says that he thought Bon's home was a bankrupt temple. Rin's mother says that since the temple couldn't make ends meet anymore, she took over her family's inn. Later, Rin meets Bon's father, surprising him again since he thought Rin's father would be muscular, tall and intimidating. Rin's father asks if he can't seem the resemblance, Rin says that Bon looks a lot cooler. When Bon's father says that he must be a good friend of Bon, Rin admits that he had a fight with Bon. Bon's father says he's in the middle of one with Bon too, Rin says that Bon can be a real pain. Bon's father confirms but Rin says that Bon's a good guy so he wants to make up with him. After Bon walks away after being told about what the public thinks about his father, Rin looks at his back with a sad face. When Bon doesn't take his food, Rin goes after him with a drink and a bento, he bugs him to eat until Bon angrily takes it and tells him to stop bugging him. Rin comments to Miwa and Shima that he made Bon mad. While Rin and Shima are talking Rin shows his list of cool people and Bon is on the 2nd place, only beaten by Rin's father but beating out people like Miwa, Yukio, Kuro and even Rin himself. When Rin witnesses Bon yell at his father, he sees himself fighting with his own father and his father dying because of it. Rin steps in and stops Bon's father for walking away and asks him if he's really okay with this. Rin turns to Bon and punches him. He says that while he doesn't know what went down between them, he does know that they're both going to regret this later. He tells Bon to apologize to his father right now while he still can, but Bon tells him it's none of his business and to stay out of it. When Bon's father interferes, Bon tells him to go away and never show up again. This takes Rin back again to his father's dead body. Rin says that he used to think Bon was cool, but that he was totally wrong about him while flaring up, letting everyone see his blue flames. Rin attacks Bon again with his flames, while Bon defends himself and Rin says that he didn't ask to be Satan's son. When Rin breaks through Bon's barrier, he grabs his collar and says it's different with Bon and says to tell him he's wrong, Bon looks down on the floor. Rin says to apologize to his father before he's dead, which makes Bon look at his father. Rin tells him to not make the same mistake he made, which makes Bon look back at Rin in surprise. Rin repeats to apologize to his father again, but then Juzo cuts in and separates the 2. Rin refuses to calm down even when Shura interferes so Shura knocks him out cold and Rin is put into isolation.

After his fight with Rin, Bon is with the other Exwires minus Rin and explains that Rin is in custody. When Bon hears about Rin being sentences to death, he and Shiemi are the 2 who get a close up of their reaction and seem to be the most shook up about it. Bon is also the first person to put on the poncho and thereby bust Rin out of the jail, also getting on the Vatican's bad side with it. After busting Rin out of the cell, Bon hits Rin with his sword and says he wasn't there with his head straight when they fought over his dad and that he was right as far as his dad went. He gives Rin his sword and Rin apologizes for punching Bon. Rin tells Bon yet again to believe in him because while he can't help being Satan's son, he will definitely master his flames so to please trust him. Bon snaps and says he doesn't care about that. He explains that the reason he is pissed is that Rin tried to carry the burden all by himself and never told them anything. He asked why he would trust someone like that and if he was the only one who thought they were on the same side. Rin tries to explain he never meant it like that and the others are also surprised by his reasoning. Rin mentally tells Bon that he understands it now. When the Impure King is forming and Bon prepares to go up to it to put up the barrier and Miwa and Shima protest, Rin says that he'll keep Bon safe and asks Miwa to leave it to him. After the 2 of them start moving, Bon's father tells them to be careful and apologizes, Bon tells him to not die on him, while Rin is behind him with a smile on his face. When they get to the point where they can clearly see the Impure King, Bon tells Rin that they need to hurry up, but they come across Kuro. Kuro tells them he'll get them up there, although Bon is reluctant. While they are looking for somewhere to land to put the barrier up, Bon is having doubts about if they could beat it, but Rin's stomach starts gurgling. He says he's really hungry since he skipped dinner, Bon asks how he could be so calm and that he's freaking out. Rin says it's because he lost fair and square when they did rock, paper, scissors to see who was gonna go up front, Bon says that's not was he's talking about and how Rin is currently just a strong guy with a stick and if he's not scared. When they land on the rocky spot, Bon asks if Rin's not wallowing in despair again, Rin says he's fine and it seems like Bon is the one freaking out right now. Rin says that everyone is probably doing the best they can at the moment and that they have to do the best they can too. Rin says: "You just focus on making that barrier, Princess Suguro!" This makes Bon angry and embarrassed and asks who he's calling princess and that he'll beat him to a pulp. Rin argues that Bon was just practically in tears and that he surely doesn't want to play knight to such an unladylike princess like Bon. Bon says he was gonna do that anyway and Rin says he'll leave it to him then. Bon sees Rin's hand shaking in fear even though Rin's smiling and saying they'll win. Bon thinks to himself that he knows deep down Rin isn't an idiot, but both him and his dad are always pulling the tough lone wolf crap and that pisses him off. After Bon casts the barrier, Rin compliments him by saying he's awesome. When Bon says he'll die before he'll break the barrier, Rin tells him to lighten up and calls him princess again, he also says Bon will pass out if he keeps freaking out. Rin and Kuro keep fighting and protecting Bon, but the sporangium bursts, releasing a dense cloud of toxic miasma. Rin tries to get close to Bon and keeps calling out his name but he doesn't manage to get close until Bon casts another spell. The Impure King tries to attack them again and Rin desperately tries to draw his sword but to no avail. Bon tells Rin to get out of here while the barrier is still up and to evacuate as many people as he can. Rin suddenly starts talking about Kyoto Tower and tells Bon to take him there tomorrow. He says it would really suck if Kyoto doesn't make it and everyone isn't okay so tells Bon that they'll win and go home. Bon asks why the hell he's interested in Kyoto Tower of all things and it'd be embarrassing to ever go up there as a Kyoto native. He says that Kyoto is full of famous places, but Rin says he wouldn't know anything about temples and stuff and that he thought it was a trendy spot. Suddenly Bon starts laughing and thinks to himself that Rin is actually terrified. Rin is confused and asks if he's okay, Bon says he is and that he'll buy into Rin's false bravado, since they're friends and all. He says he'll believe in Rin and removes the spell protecting him. He immediately gets covered in fungi and Rin manages to draw the sword, overcoming his mental block. Shura comes in and saves Bon and tells Rin to defeat the Impure King and Bon says for him to go for it.

After the Impure king is defeated and Bon sees Rin with his back turned to him and Shura, he starts walking towards him and calling out his name. Rin excitedly explains that he can control what he burns now. Later, when Rin expresses his desire to go to Kyoto Tower, Bon says: "Here we go..". When Miwa says there are a lot of other sights in Kyoto, Bon says that he told him so. Bon says that Miwa should humor him since it's Rin's request and teases Rin by saying Rin will burn Miwa to a crisp if he refuses, the others later tease him with that too when Rin asks for a picture with them. Bon eventually puts his hand on Rin's shoulder and says he doesn't have to beg them for one little picture, making Rin smile with a blush on his cheeks.

Exorcist Cram School Enrollment arc
The 2 of them are first seen taking note of each other when Rin falls asleep in class and gets woken up by the teacher. Bon comments on it loud enough for Rin to hear, he asks what's up with Rin and why he's even here, although he doesn't directly address Rin. After Rin turns around, Bon tells him to beat it. Rin realizes that Bon has been the one that has been glaring at him since the start of school. He also comments on how his hair must take a lot of work, also that it's pretty cool and how everything about Bon screams hostile. Rin turns back around and says that in the past he'd have glared back and probably fought him later, but he won't get involved with those types now that he's made up his mind about becoming an exorcist. After Rin falls asleep again, Bon is visibly annoyed glares at him. When the cram school students get their tests back and Bon is called to the front to collect his test score after Rin went, Bon says he couldn't get a 2 even if he tried and that Rin should try studying instead of trying to show off and that he makes him sick. Rin asks himself what that damn stripe-head's (Bon) problem is and that he's the one trying to act all cool. However Rin is completely shocked to see Bon's test result, which is a 98 (meaning that if you add Rin's score, they'd have the full score). Rin expresses his surprise out loud, saying that someone like Bon getting a score like that is impossible. Bon gets angry at that and tells him that he comes to these classes to learn and earn the right to call himself an exorcist. He also tells Rin that he's not the only one and that everyone here is serious about becoming an exorcist and that half-assed punks like Rin should just get out of their sight. Rin calls him a stripe-head again and asks what gives him the right to say that and that he's working just as hard as everyone else to become an exorcist, however in his mind he comments on how serious Bon is. Bon yells that he's never seen Rin pay attention in a single lesson, while being held back by Shima and Miwa and Rin defends himself saying that he's more of a practical person and isn't good at things that don't requite moving around, while being held back by Yukio. After class, Rin asks Yukio about Bon and Yukio tells him he's a prodigy who's here on a scholarship just like himself. When Shiemi and Rin are alone, Bon interrupts with Miwa and Shima in tow and says they seem to be having a good time. Bon assumes things about Rin and Shiemi's relationship which Rin gets angry and embarrassed about. Rin then angrily points out how Bon is always hanging around Shima and Miwa. He asks if Bon can't handle himself and that Bon's pathetic. Afterwards, Bon and Rin glare at each other and Miwa and Shima who are watching think to themselves that they're really alike. During practical athletics, Bon and Rin are paired together to run from the Reaper (a giant toad demon) and they're competing instead of thinking about the Reaper. Rin has the lead and says that Bon can be as smart as he wants but it won't help him in the real world. Bon thinks to himself that Rin is seriously fast. Bon then kicks Rin and tells him that in the real world he'd do anything to win, however this causes the Reaper to nearly get him if it wasn't for the teacher's interference. Rin asks what the hell that for was, Bon answers that he didn't want to lose to Rin even if it killed him. The end up physically attacking each other and they get pulled apart by the teacher and Bon's friends, Rin not struggling but showing Bon the middle finger and Bon struggling in his friends' grip. The teacher ends up talking to Bon in private, with Rin looking at them from a distance and asking why only Bon was pulled apart. Rin asks what's wrong with Bon anyway. Shima explains that he's really serious and gets upset about trivial things like this because he joined the cram school with a crazy ambition. Meanwhile Bon is asking the teacher why only him is getting lectured. The teacher explains that he heard Rin is a special case and that Bon's better off not associating with him. This happens while Shima is explaining about Bon's ambition to defeat Satan. Rin is annoyed at how it's the exact same as his own ambition, Shima laughs and says it's a crazy ambition. Rin is confused on why Shima is laughing at Bon's ambition. Miwa explains further about the Blue Night and the effect it had on their temple, before they are interrupted by the teacher and Bon returning. After the teacher leaves to take a personal phone call, Bon comments on how unprofessional he is and yells the students are even worse, a jab directed at Rin. Rin says that Bon has been running his mouth a lot today and asks what makes him think that he's not taking this seriously. Bon says it's the way he acts in class and thinks that Rin is just some rich kid getting special treatment. Then Bon challenges Rin to touch the Reaper without getting attacked and he'll acknowledge Rin if he does that and that he'll do it too of course. Rin says it sounds interesting but he still won't do it. He further explains that he could mess up and get himself killed and that he's not stupid. He says he's got ambitions just like Bon so he can't go around getting himself killed for such a small thing. Bon realizes Shima and Miwa told Rin about his ambition. Bon feels like he's being made fun of and remembers being made fun of as a child. He asks Rin why he doesn't try to fight and if he's not bitter at all. Bon then says he'll do it and that he should just stand there like a coward and Rin, Miwa and Shima try to stop him. Just when he's about to get attacked, Rin stands in front of him and takes the brunt of the attack, saving his life. After making the Reaper bake off, Rin scolds Bon and asks him if he's a complete idiot. Rin declares that the one to defeat Satan will be him and that Bon should just get lost. Bon is completely caught off guard. When he manages to talk normally again he says Rin is the idiot and he could've gotten killed. Bon also tells him to not copy others people's ambitions. Rin argues that he's not copying anyone and that the ambition is his own. The next day in class, Rin is struggling to read with his bangs in front of his eyes and Bon walks up to him. Rin asks if he's here to make fun of him as well. Bon ends up thanking him for saving his life and gifts him a hair clip that he uses to keep his hair out of his eyes when he's studying late at night. Rin comments that this is creepy and asks if it's some kind of omen, angering Bon who says he's trying to be nice. Rin is seen wearing the hairpin multiple times after that.

After receiving a form where they need to fill in their meister. Rin is unaware of what this means and goes to the Kyoto trio for help (Bon, Shima, Miwa). Bon is annoyed at his unawareness and tells Miwa not to tell Rin anything. After hearing that Bon is going for 2 meisters, Rin says: "Seriously? As expected for Bon!" Bon gets angry at this and tells him to call him Suguro and that he won't forgive him for acting all friendly with him. After getting angry at Rin's unawareness again, he angrily explains what all the meisters mean. Later after making a worksheet, Rin saying he's going to go grab some air while looking out of it, Bon tells him to go cool down. Another day in class after perfectly reciting a passage, Rin loudly says that it was cool and that Bon really was smart after all. When 2 ghouls attack again, Rin goes to draw the ghouls away by himself while Shiemi is holding it back. Bon yells after him to get back here but Rin has already gone. After Bon nearly gets killed by the ghoul that stayed behind, Rin manages to turn the power back on and unknowingly saves Bon and allows him to defeat the ghoul. Rin gets back to the room, much to the surprise of everyone, especially Bon who asks what happened to the other ghoul. Rin says he defeated it and then gets punched by Bon, who yells at him and asks him if he was trying to get himself killed. After the ghoul attack which turned out to be an Exwire authorization exam, Rin is asked about how he defeated the ghoul and he says he just stabbed it with his sword. Bon says that's way too vague and that to him Rin is biggest mystery of all.

When Rin gets back to class after Amaimon's first attack, Bon comments on the fact that Rin seems different, although after he struggles to read a chapter, Bon takes it back. While setting up tents in the forest for the summer training camp, Rin says it's becoming more like picnic now, Bon responds that it's a camp and that he should stop hitting the tent. When the tent collapses, Bon says that that's why he told him to stop hitting the tent.

Before they start the mission to receive permission to go on real missions, Rin is seen looking distracted after a conversation with Shura. Bon notices and asks with a grin where Rin's earlier energy went and if he's scared. Just after the mission starts, Rin uses his flames to save Shiemi, who is unconscious. Bon saw the light, however was blinded by it so didn't realize what it was. Bon asks what the light was and explains he couldn't see what it was, Rin says he couldn't either and deflects the question. Bon also asks about Shiemi and Rin says she seems to be fine but is bleeding from her head. After Rin asks why Bon is even here, Bon says it's to help. Rin says Bon was the one who said he wasn't going to help anyone. Bon is embarrassed and yells at him to shut up and that no one could ignore a scream like that. Rin laughs and says since Shiemi looks like she'll be alright that he can just leave everything to him and he'll bring back Shiemi and retrace his steps back. Bon goes to say something but is interrupted by Shiemi waking up. After Bon drew the plan to let the peg lantern cross the swamp himself, Rin excitedly compliments his drawing and asks him to draw a picture of him. When Rin gets caught by the giant moth, he tries to make everyone go on ahead so he can use his flames. Bon says he's doing it again and Rin apologizes, Bon says that they'll help him of course, surprising Rin. Bon manages to hurt the moth long enough for it to let Rin go. Rin thinks to himself that it was really cool. Bon tells him to run, confusing Rin who thought Bon had just "kicked his ass". While they run away from the moth, Rin thanks Bon but Bon tells him not to since he was just paying him back, which confuses Rin. Bon elaborates by saying he saved him and he, who has the same dream as himself, said it without embarrassment. Rin says he just doesn't tend to think too deeply about this kind of stuff, but Bon says he doesn't think he's stupid, however that he should stop trying to fix everything by himself and to not forget he has friends. When they get back to camp and get attacked by Amaimon, Shura throws Holy Water on the Exwires, however skips Rin. Bon notices and asks why he doesn't do it for Rin. Shura says he has an allergy for Holy Water, greatly surprising Bon. After Rin rushes after Amaimon and Shiemi, Bon angrily notes that Rin is doing it again and rushes in after seeing Rin being beaten by Amaimon. When the Kyoto trio goes after Rin, Amaimon and Shiemi, Bon interrupts their talk by firing off firework in their direction. Rin calls him an idiot and tells him to run. While Bon is being choked by Amaimon, he says that the one who pissed him off was Rin not Amaimon. He further explains by saying that Rin has been off running around saving people without thinking of himself since the beginning and does amazing things without having any special powers. He says Rin is an enigma and asks him what the hell he is. This pisses Amaimon off and he squeezes harder and Rin yells out for him to stop and decides to draw his sword to protect his friends but exposing his identity as Satan's son. Rin loses control due to fighting a very powerful foe for extended period of time. Afterwards when the sword is put in its sheath, he regains his sense of self and he sees Bon standing with the others with a contemplating expression. He asks Bon if everyone is alright. Bon gets angry at this and yells: "Why... the hell is Satan's kid here at the academy?!" This surprises Rin. Bon coughs after yelling and before leaving he looks back at Rin with an angry expression.

However one of the Baryon ends up jumping on Shiemi's back and Rin goes to help and lets out his flame to burn the Baryon. But he gets stopped by Bon who's yelling and grabbing his shoulder despite the flames. Rin grabs Bon by the collar and yells at him that he had everything under control and to have faith in him. Bon gets angry at this and asks how he could do that, he talks about how on the Blue Night the followers at his temple died in those flames and yells that blue flames can kill people. He goes further talking about their family members who died and asks how he could have faith in Rin after what has been done to his family. Rin empathizes and says that it must've been horrible but yells that it had nothing to do with him. Bon remembers that Rin said he'd defeat Satan. Rin confirms and yells to not lump them together and starts flaming up but they get interrupted by Miwa. After meeting Bon's mother, Rin is greatly surprised as he expected someone more brutish. Rin is also surprised because he thought Bon's family home was a bankrupt temple and not the inn they're currently in. He also comments on Bon's mother and says she's quite the looker. Bon's mother explains and also says Rin's quite a frank boy but doesn't seem to be annoyed at all. Later, Rin also meets Bon's father, surprising him again since he thought he too would be more brutish. When Bon's father laughs and says they look quite similar. Rin says that Bon looks a lot cooler. Bon's father says he must be good friends with Bon then. Rin admits they just had a fight, to which Bon's father responds that he's also in the middle of a fight with Bon. Rin says that Bon is a troublesome one to deal with and Bon's father agrees. Rin then says that Bon is good guy though so he wants to make up with him to which Bon's father agrees. Later, when the Kyoto trio and Rin go to help bring bentos to the field office, Rin carries a lot of them and Bon's mother says he's really strong and then tells at Bon to get to work too. After they're done, Shura let's them have bentos too and Rin is so hungry he's drooling and unable to speak properly, to the silent disgust of Bon. However Bon doesn't take the bento and goes to leave, but Rin follows him and pesters him to take the food since he noticed he hasn't eating anything all day. Bon snaps and takes it and yells at him for being noisy and leaves. Rin watches him leave and comments on how he made Bon angry. When Rin is talking to Shima and calls him uncool, he takes out his coolness ranking paper. Bon is 2nd place, only beat by Rin's father.

When Rin and Shura arrive while Bon is yelling at his father. When Bon yells that if his father is just going to brush everything off again he won't acknowledge him as his father till the day he dies, Rin is reminded of when he yelled at his own (adoptive) father after which he died. Bon's father goes to leave but Rin stops him and asks him why he's walking away and that he's Bon's father isn't he. Both of them are surprised to see him interfere. When Rin turns to Bon, he punches him. Rin yells that he doesn't know the details but that he does know Bon will regret it later if he doesn't and tells him to apologize while he still can. Bon yells that it has nothing to do with Rin and to shut up. Rin yells back to not cut off his father so nonchalantly. Bon says he doesn't want to hear that from Rin, who said he was going to defeat Satan. Bon's father tries to calm the situation but Bon yells at him to just leave and not come back. Rin says that he thought Bon was a pretty cool guy at first, but he was completely wrong about that. Rin then flares up, exposing his flames in front of everyone. He goes to attack Bon who defends himself. Rin breaks down Bon's defense while yelling that he didn't ask to be Satan's son and says it's different for Bon while grabbing his collar. Bon looks down at that, but they are interrupted. When Shura chants a mantra to calm Rin down, which hurts Rin's tail and he cries out in pain, Bon stays where he stands but weakly reaches a hand out and calls his name. Rin refuses to calm down and is knocked out. Afterwards Bon is with the other Exwires minus Rin and explains that Rin has been detained because he flared up. When asked what will happen to Rin, Bon says he doesn't know and that Rin is in a cell in the branch office. After Shima points out Rin must be in a bad spot right now, Bon is seen looking down at the floor. Because of his flare up, Rin has been sentenced to death and after hearing that from Shura, Bon visibly reacts. Shura also entrusts Bon with Rin's sword (which used to be from the Myodha Sect) and the letter Bon's father wrote to Rin. Shura asks the Exwires to break Rin out. After reading the letter, Bon immediately goes to save Rin, being the first to do so. When Rin breaks out and gets emotional about everyone coming to save him, Bon hits him with his sword in his side. He admits that Rin was right about his father and tells him to take the sword since he needs it. Rin apologizes for attacking him. Bon turns to leave and says he will take him to the mountain and after that he can riot as he wishes and he will fight with all he has as well. Rin tells Bon to believe in him and that he can only control his flames a bit but to please believe in him. Bon says that doesn't matter and that the thing he can't forgive about Rin is that he's always carrying such a huge burden on his own. He yells that Rin is the one who treated them like outsiders and asks who would trust him again. He then says that him being Rin's companion was just his wishful thinking after all. Rin denies that he never meant to that, however he starts to understand and that he must prove himself in actions from now on. When Bon goes to set up the barrier, Shima and Miwa try to stop him, but Rin interferes and says he'll protect Bon. Bon is extremely surprised and Rin says it'll be fine since he can use a little of his flames and he's physically strong. Rin asks Miwa to leave protecting Bon to him. When Rin and Bon prepare to leave, Bon tells his father not to die, with Rin smiling behind him.

Rin and Bon are greatly surprised when they see the Impure King up close, who has taken the appearance of a building. Bon tells Rin they need to hurry up or it'll be bad, Rin casts a worried glance at him though since Bon doesn't look very good. They get interrupted by Kuro, who eventually offers to take them to the Impure King. While they're looking for a place to land, Rin says that the sporangium looks like a giant meat bun, surprising Bon who asks how he can think calmly right now. Bon admits that he's scared to death at the moment. Rin says it's because Bon lost at rock, paper, scissors so it can't be helped. Bon yells that he's not referring to that and explains that Rin is unable to draw his sword so he is just a weird strong guy with a stick and asks if he's not scared at least a bit. When they land at a rock place, Bon asks if Rin isn't thinking about giving up. Rin says that this time, there's no way. Rin then asks if Bon is scared and explains that everyone is doing their best right no so they have to do their best as well. He then says that 'princess Suguro' just has to focus on setting up the barrier. This both surprises and angers Bon, asking who's a princess and saying he'll punch him. Rin says it's because Bon is all scared and sniveling and that he doesn't want to play knight to such a crude princess. Bons says he'll prove it to Rin, Rin answers that he'll leave it to Bon then. Bon then notices that Rin's hand is shaking before Rin says that they'll win. Bon thinks that he understands that Rin is not an idiot and knew that a long time ago. However that both Rin and his father always try to act heroic by themselves and that things like that really piss off. When Bon finishes the barrier, Rin excitedly compliments him by saying that was amazing and really cool. Rin and Kuro resume fighting to protect Bon from the Impure King. After Bon says he won't break the seal even if he dies, Rin tells him to not get his royal panties in a twist and calls him princess again. Bon yells at him to quit with the princess thing. Rin says Bon needs to focus for now and he can do dying later. A few times Bon ends up warning Rin where the miasma was and Rin also directly saves Bon when the miasma gets too close. However the sporangium and Bon ends up wheezing and coughing harshly. Rin runs towards him calling his name and asking if he's okay. Bon makes Karura protect him however it's draining his strength much faster. Bon says he probably won't even last 15 minutes. Rin desperately tries to pull his sword out put it doesn't work. Bon watches and tells him it's the end. He tells Rin to get out of there as fast as he can while the barrier is still up and to help people take shelter. Suddenly Rin starts talking about Kyoto Tower and tells Bon to take him there tomorrow. Rin explains that that's why he needs Kyoto and everyone to be safe. Bon yells and asks why he's interested in Kyoto Tower of all things and that he has never climbed because he would find it embarrassing. Rin is surprised and Bon says Kyoto is full of other famous spots. Rin bashfully says that he doesn't know anything about temples and stuff and he wanted to see trendy spots. Bon ends up bursting out in laughter and thinks: "This guy... he's there scared and yet..." Bon says he'll support Rin's confidence since they're friends. He says he'll trust Rin and breaks the part where the barrier protects him. Rin manages to draw the sword at this and burns the Impure King. Shura arrives and tells Rin to leave Bon to her, while Rin goes to defeat the Impure King. When Rin goes to fight the Impure King, Bon pleads to him, making Rin smile. After defeating the Impure King, Bon wakes up and asks what happened. Shura tells him to look and Bon sees Rin putting his sword back into its sheath. Rin excitedly tells them he can control what to burn now. When the Exwires get the next day off and go sightseeing, Rin asks to go to Kyoto Tower. Bon says: "There he goes." with a slight smile, Miwa says there are better places. Bon tells Rin that he told him so, however says as a joke that Miwa should grant his wish since he's Satan's son and will burn him to ashes if he refuses. After going to Kyoto Tower, Rin asks the Exwires (+ Yukio) to take a picture with him there. Bon goes with the previous joke he started and says they can't refuse since it's Satan's son and he'll burn them down. Bon pats Rin on the back and says he doesn't need to ask permission every time, Rin is seen smiling with a blush on his face after this.

Later, Bon tells Light that he couldn't be honest with Rin or Yukio this morning after taking part in the death of their family member. Bon calls Rin by his name, while he calls Yukio "sensei". While hearing about the Blue Night from Mephisto, Bon thinks about Rin and Yukio and his memories of them and about their fate. After Yukio threatens Bon to tell him about his and Rin's birth, Bon asks Rin if he can talk to him tomorrow. Later when they're back at the dorms, Rin tells Bon that if he's done, his breakfast is ready and Bon asks him to talk privately. Bon starts saying that he wasn't sure if he should tell Rin, but he's going to. Bon says it's about Yukio and Rin asks if anything happened, surprising Bon. They get interrupted by Shiemi. After Bon says what happened, Rin weakly says he finds it hard to believe Yukio would do that. Bon says it's true and talks about Yukio threatening him for information about their birth, Rin remembers Yukio talking about how he wanted to know about their birth. Shiemi talks about what happened between her and Yukio and Rin runs away and Bon calls out after him. When he returns and tells the Exwires about Yukio possibly inheriting Satan's flame, Rin says he's going to go help Yukio and goes to leave. Bon immediately pulls him back and tells him to think about it, Rin responds that he's got to go talk to Yukio. Bon says he hasn't thought about the consequences and both of them would be gone in that case. After the Exwires attempt to rescue Yukio and Rin ends up drawing his sword after Yukio shoots him, Bon attempts to tell him to stop. Rin's sword ends up breaking and Yukio leaves. The Exwires run towards Rin who is struggling, Bon calls his name and asks him if he's okay. When Rin appears to be dead with his body completely burned, Bon says: "No way! Hey.. he'll come back to life, right? I mean, this is Rin we're talking about!!" Rin's demon heart appears and Bon clutches Miwa in happiness with a tear in his eye and tells them to look. Rin's normal body returns although with some slight differences, Bon runs towards him and yells his name. Izumo says to give him so clothes since he's naked, Bon tells her to give it a rest, but notices something is wrong with Shiemi. Shiemi explains that Rin's not just warm anymore and Bon asks her what she means. After Rin's demon side takes full control and he prepares to attack the Exwires, Bon yells at him to come back to himself.

Of One Cloth arc
A lot of chapters later, Rin and Yukio are reunited with the other Exwires. Rin wakes up and sees everyone, Bon greets him with a "Good morning" and after Rin dramatically tears up and rubs Miwa's head, Bon says he's acting like it has been ages. While Yukio attempts to apologize for drawing a gun on him, Bon says it's really confusing to call one Okumura and the other Okumura-sensei sometimes. Bon proposes to use their first names (something that he has already done before however not directly) and asks if it's alright. Rin immediately agrees, although says that since Suguro is easy to say, Rin will keep using that and Bon agrees.

Blue Exorcist The Movie
The Kyoto trio goes to Rin and Yukio's dorm to wash up and Bon calls out to Rin to see if he's there. He also questions Rin when they find Mephisto's shampoo there. After washing Usamaro, the Kyoto trio goes to leave again. Bon says that just bathing took up all their break time and Rin thanks them for helping out. Bon says they'd do they same if Rin was in a pinch. Later, when talking to the Exwires minus Shiemi and Rin, Bon questions if it's okay to give Usamaro so much freedom, since Rin is supposed to be guard it because it's a demon. The next day, the Kyoto trio goes to Rin's dorm again to use the bath and see Rin playing with Usamaro outside, Bon loudly asks what Rin's doing. Rin explains they can't stay inside all day and invites them as well. The Exwires end up playing baseball with Bon as pitcher. When Rin is up as batter, Bon immediately gets an annoyed face. Rin signals a home run, annoying Bon who yells if he knows how fast his straights are. Bon throws the ball and tells him to try and hit it, Rin ends up hitting the ball just fine. He taunts Bon while running by saying it was too easy, angering Bon. After Usamaro saves the town and takes everyone's memories except for Rin's, he runs out of his dorm and runs into the other Exwires. Bon asks him what's wrong and that he's looking all flustered. In the credits, Bon is seen with a baseball bat pointing at Rin, who's smiling with a small blush and wearing a baseball glove.

Fanon
BonRin is one of the most popular slash ships within of the Blue Exorcist fandom, perhaps the most popular one. The events of the Impure King Revival arc and the Kyoko Saga anime of the arc inspired fans to support the ship. Due to how the two first started out as rivals who couldn't stand one another before they became friends, fans sometimes feature that rivalry in their fan art, along with having the two using it as a means to hide the feelings they began to have for one another.

On AO3, BonRin is the most written ship for both Bon and Rin. It is also the most written ship in the Blue Exorcist tag, beating out the 2nd most popular romantic tag with over twice as many fanfics and beating out the 2nd relationship tag with over 200 fanfics. Just as Fanfiction.net has 371 fanfics on the two and currently has 89+ fanfics under pairing. Both Tumblr and DeviantArt also has many fanart drawings of the ship. Some Tumblr users have their Tumblr accounts as BonRin fanbases, while DeviantArt has a fan group on the ship.

Although it's a controversial ship, one of the biggest, if not the biggest, rival ship is the Okumura Brothers. It's controversial because of it's incestuous nature, however if done in a platonic way, it can go alongside BonRin with no polyship. The other big rival ship is RinShi. BonRin can be shipped alongside IzuShie and Yukishima.
