Manga / Blue Exorcist

Go To

Mephisto: But Rin, you have chosen a path full of thorns. A sad and painful fate awaits you... so much it will make you wish you had died here.
Rin: I don't care! I'm no longer human, but I'm not a demon either. I can only move forwards! I'll become an exorcist!

Blue Exorcist, also known as Ao no Exorcist, is an action comedy fantasy shonen manga with Multiple Demographic Appeal by Katou Kazue.

The story revolves around Rin Okumura, who starts out as a boy who is somewhat of a delinquent and as such gets into fights. He is usually at odds with his adoptive father, Father Shirou Fujimoto. One day, while Rin goes to a job interview that Fujimoto 'encouraged' (read 'encouraged' as 'threw objects at') him to check out, he starts seeing little black 'bugs', and runs into a group of kids he fought the other day. To his surprise, one of the kids is now a demon. Just as the demon is about to kill him, blue flames surround his body and burn his attacker. The demon realizes that Rin is the one he has been searching for: the son of Satan.

While Rin is in total shock and disbelief, Shiro Fujimoto comes and exorcises the demon. He then describes how demons come from a world called Gehenna and can cross into our world (Assiah) by possessing a vessel of sufficient strength. He takes Rin back to the house to give him a sword that seals his demon powers and see him off, but unfortunately, Rin thinks it's all bullcrap and accuses Shiro of throwing him out. Double unfortunately, Satan decides to come in and say hello. Rin saves himself by drawing the sword, but Father Fujimoto dies in the process. After the funeral, he is confronted by Mephisto, a member of the True Cross Order and a friend of Shiro's, and demands to join the True Cross Order and become an Exorcist.


The series follows Rin's quest to become the strongest exorcist and to defeat Satan. It also sidetracks onto secondary characters, namely Yukio Okumura, Shiemi Moriyama, Shura Kirigakure, Ryuuji "Bon" Suguro, Renzou Shima, Konekomaru Miwa, and Izumo Kamiki. All of which are not exactly who you first think they are; Deconstructions, Reconstructions, Played With, and Subverted tropes abound here, especially in regards to characters.

A 25-episode anime adaptation with music by Hiroyuki Sawano began airing on April 17, 2011. You can find it on Viz Anime, Crunchyroll (free simulcast) and Hulu. The English dub can be seen on Neon Alley for the PS3 as of October 2, 2012. It also is now available on Netflix with the option of either sub or dub. A movie came out in December 2012 and the anime is a member of the Toonami block as of February 23, 2014.


A new anime covering the Impure King arc aired in 2017 as part of the Winter 2017 Anime lineup. The English dub for the season can be found on Hulu.

This series provides examples of:

  • Aborted Arc: In the first chapter, Reiji mentioned that he'd be attending True Cross Academy thanks to his family's connections. After Fujimoto exorcised him, he mentioned that he could potentially get possessed again if he continued to give into his sinful behavior (and in the anime, he did). Those lines seemed to imply that he was going to be a recurring character and maybe even Rin's rival. However, he never appears again after his exorcism and the role of The Rival ended up going to Ryuji instead.
    • It's only just touched upon, but we see flashes of Izumo's backstory in one early episode. Though it was eventually covered in the manga, it never came up again in the anime which went in another direction. Though possibly averted now that the show has gotten another season that continues the manga and ignores all the original content the first season created.
  • Academy of Adventure: True Cross Academy, with demons showing up on the grounds, mysterious, possibly villainous teachers, and the True Cross Order having not only a base there, but a school for exorcists.
  • Adaptation Expansion: The first half of the anime, before it diverges onto an anime-original story.
    • The movie expanded on the Phantom Train omake. Notably, the mission goes much worse. Rin isn't able to destroy the train after Shiemi frees all the souls, and it manages to escape, causing a large amount of property damage. Rin and Shiemi are suspended for disobeying Yukio's orders, and Yukio never actually comes around to saying that Rin was correct in wanting to save all the souls on the train. After the fact he even tells Rin HE was in the wrong. And Yukio spends most of the movie hunting down what was left of the train.
  • Adult Fear: Your adopted child is the biological son of the most powerful demon in existence and if you let your guard down for even one minute said demon will possess you and use your body to literally drag him down to hell.
    • Your daughter has become a shut-in who only cares about her deceased grandmother's garden, and on top of that she can barely move due to demonic growths in her legs.
    • Both of these are terrible examples of this trope. The boy you have raised rejecting you because he was adopted, or your daughter becoming a shut-in who becomes obsessive about her garden are better examples.
  • Alliterative Name: Arthur August(e/o) Angel.
  • All Myths Are True: All Religions Are True: The series mostly focus on Christianity, mainly Roman Catholicism, but there have been demons inspired by Shintoism, Fatal Verses from Buddhist sutras (at least Zen Buddhism anyways), even Greco-Roman minor deities.
    • It was also said in the manga that almost all demons found in other religions are true, Satan just happens to be the lord of them all.
  • And the Adventure Continues: In the anime at least.
  • Animal Battle Aura: The hilarious Rin vs. Ryuji scenes in the anime have these. Rin is a golden tiger, Ryuji's a green-scaled Chinese dragon.
  • Animal Motifs: Konekomaru Miwa and Mamushi Hojo.
  • Anime Catholicism: The series uses Bible verses as spells. Combined that almost every preacher met is that of the badass variety, it can arguably be considered the Trope Codifier.
  • Anthropomorphic Personification: Demons are revealed in the manga to have originally been concepts that resided in Gehenna. The growing numbers and advancement of humanity, however, caused them to gain physical form and with it develop ego. Unfortunately for the most powerful demons, the Kings, their new form forces a painful degradation of their bodies due to the power they wield. When the body dies they reincarnate into a new physical form only to repeat the cycle. Satan is the manifestation of Gehenna itself that all demons originate from.
  • Anti Anti Christ: Rin is a good-hearted guy who wants to KICK SATAN'S (read: daddy's) ASS.
  • Antihero:It turns out the entire Order of the True Cross is this. It is revealed that there was a secret division that was growing clones to be subjected to various painful experiments with the ultimate goal of them being possessed by the Kings of Hell. And the clones were otherwise children with personalities of their own (in fact, 2 of them grew up to become Father Fujimoto and Arthur Angel, clones of Azazel and Lucifer respectively (though the latter apparently had his mind wiped and does not currently know about his origin). Rin is horrified when he finds out. However, they are still heroic because it is all being done to placate Lucifer who is threatening to destroy the entire world if they cannot create a body for him that won't decay and rot rapidly, as he is essentially in constant pain due to not having a host that can support his immense power.
  • As the Good Book Says...: Certain Bible verses can be used to banish demons. The trick is knowing which Bible verse is required for which demon. One classmate, trapped by a ghoul, only knows that something from the Book of John can banish it. He recites the entire thing from memory, and it turns out it's the last line that banishes the ghoul.
  • Barrier Maiden: Suguro Ryuji in the fight against the Impure King. Made fun of by Rin because the role is usually reserved for girls.
  • Beach Episode: 11th episode of the anime, and Chapter 35 to 37 in the manga.
  • Bedmate Reveal: After the battle with the Impure King, Rin wakes up to find Shiemi sleeping next to him.
  • Berserk Button: Surprisingly, Takara manages to push Konekomaru's, sending the latter into a yelling spree. Resulting in a Get a Hold of Yourself, Man! from Ryuji.
  • BFS: Angel's sword isn't huge, but it's definitely the same thick "chopper"-type as Cloud and Allen's.
  • Big Damn Heroes: Suguro Tatsuma pulls off the beginning of one at the end of chapter 24. It backfires.
  • Big Ol' Eyebrows: Kamiki Izumo, causing her to get the nickname Eyebrows.
  • Big "WHAT?!": Ryuji in Chapter 28 when told by Rin to ride on the giant Kuro.
  • Bishōnen: Angel is intentionally drawn in this manner. Lucifer, too. Lampshaded by Gedouin, who compares his appearance to a shining star, complete with the sparkles.
  • Bizarchitecture: True Cross Academy.
    • The Order's main base in the Vatican seems to have weird design choices - what is with that big meeting room and table surrounded by huge black pits?!
    • The Impure/Defilement King (a demon in the Decay domain) takes the form of a giant city.
  • "Blind Idiot" Translation: One specific example that ruins foreshadowing for the fact that Arthur is one of the clones of Lucifer. Too bad his name is rendered as "Arstur" in the logs (and for that matter, Lucifer is spelled Lucifel at the top of the page.)
  • Body Horror:
    • Demon mashou boils. And demonic possession/attacks. So much blood...
    • Then came Chapter 32. Toudou can regenerate with Karura's power. He just likes to regenerate his hands and mouth first, to Yukio's abject horror.
    • In chapter 56 there are uber-zombies created by Dr. Gedouin vary in just how bad they are but one has a stack of noses running up one side of the body, ear-covered arms, eyes on the shoulders, a huge mouth, multiple arms on one side of the body, what look like smaller faces on the hips.
    • In chapter 98, after Rin's sword breaks and his demonic power housed in it floods back to his body, he is incinerated by it, leaving a charred husk that falls apart when it falls over. He gets better physically a few moments later when his demon heart returns to his body and reforms it though. Mentally though...
  • Breaking Speech: To Yukio, from an exorcist who turned to The Dark Side. Apparently the guy fell behind his father and brother and after trying to live up to them, he resented them for it. Yukio declares he's different.
  • Breaking the Fourth Wall: Chapter 44 begins and ends with Mephisto explicitly holding a conversation with the reader about the plot and the nature of human desires.
  • Break the Haughty: When Izumo's confidence fails, her familiars try to kill her.
  • Broken Masquerade: Demons start appearing in masm and on television, leading to the True Cross Academy eventually having to give at least an abridged explanation that demons really do exist. Once the gate opens fully, everyone starts seeing them.
  • Bullying a Dragon: Rin was bullied and called a demon throughout his childhood due to his Super Strength and temper.
  • Calling the Old Man Out: Rin to Satan. Ryuji to his dad. The latter wasn't really called for though.
  • Calling Your Attacks: Rin starts doing this eventually. It's lampshaded by Suguro, then justified; Shura taught him to do it in order to call on his power more effectively, like a mnemonic
  • The Cameo: Renzou's siblings appear for a few seconds in the movie, even though the arc they were introduced in never happened due to the show's Gecko Ending.
  • Cast of Snowflakes: Notably, the only characters who look alike are related (Rin and Yukio, Mephisto, and Amaimon), and even then they're easy to tell apart.
    • This style means that the Kamiki family's very similar looks stand out. They look like they could be clones in fact!
  • Cerebus Syndrome: The Izumo Rescue arc is horrifying compared to those which proceeded it. As of this writing, it looks like the series is going full Darker and Edgier. To be fair, the series started with Satan possessing Rin's foster father and then ripping off his fingers before going on to toss Rin into a creepy gate. The dark aspects are just now finally starting to take center stage. Boomerang Cerebus Syndrome perhaps?
  • Chekhov's Gun: The plant nutrient bullets in ch3 come roaring back in ch77, where Yukio uses them once again to trick a demon though aren't as an effective a trick that time.
  • Chekhov's Gunman: The Video Game Dude and Bunny Rabbit Puppet Kid. The Video Game "Dude" is really Kirigakure Shura, a big boobed Upper First Class Exorcist with a seal for a demonsword on her chest, who was Fujimoto's former student and has now become Rin's mentor. Bunny Rabbit Puppet Kid is actually Takara Nemu, a fully trained exorcist, with the same rank as Shura (Upper-first class), hired by Mephisto to act as a "moderator" for the cram school students.
  • Christmas Cake: Shura does not react well to those who suggest she is NOT eighteen.
  • Church Militant: The True Cross Order, combined with a Wizarding School.
  • Conspicuous CG: The Gehenna Gate and "Messiah" (read: atomic bomb mockup) in the anime.
  • Continuity Lockout: Season 2 of the anime starts right at the start of the Impure King arc without any lead in. And it renders half of the previous season noncanon without giving any nods to it. For viewers who have only ever watched the anime, it can be rather confusing why everyone hates Rin again.
  • Continuity Nod: In Episode 19, Rin states how cooking is his only productive skill. Yukio mentions quietly how he said the exact same thing, which he did in the camping episode.
  • Cooking Duel: Rin and Ukobach have one in the anime after Rin inadvertently traipsed all over his territory (being the dorm kitchen).
  • Cool Down Hug: Fujimoto gives one to Rin in a childhood flashback when the latter goes berserk over another boy calling him a "demon" behind his back.
    • In Chapter 26, Shiemi gives one to Rin after he invokes I Am a Monster on her, telling her to stay away.
    • And in the anime, Shiemi gives him one in Episode 16 to stop his berserk mode.
  • Cool Mask: Lucifer, because his face was blackened by illness. Said mask has been taken off in Chapter 56, and it's seen on a table beside his bed.
  • Cool Old Lady: The old lady who runs the inn in Aomori. She assumes that Rin and Yukio are some sort of gay couple but doesn't seem to mind at all. Yukio isn't amused however, and Rin doesn't even notice the implication.
  • Crossover Cosmology: Quite a bit of Buddhist and Shinto is mixed in as well.
  • Crystal Prison: In the anime, Rin gets this treatment when the True Cross order find out that he's the son of Satan.
  • Curb-Stomp Battle: Not as obvious in the manga, but the anime version of Rin with his sword drawn vs. Amaimon is a huge one in the former's favor. You can clearly see how the latter went from stomping the entire cast to barely keeping up the defensive. Also overlaps with No-Holds-Barred Beatdown. In the manga: Rin vs. Amaimon in Gehenna was also heavily in Amaimon's favor. Mephisto arranged this so Rin would know that if he couldn't touch the seventh-toughest demon in hell he had no chance of going against their daddy.
    • Shiemi of all people, delivers one to her chimera zombie in Chapter 58.
  • Custom Uniform:
    • Angel has an extremely fancy uniform.
    Rin: ...when I become Paladin, I won't be dressing like a fashion reject.
    Angel: You misunderstand. I had this outfit tailor-made.
    • None of the main characters wears their uniform like the others. They use shirts, t-shirts, over the knee socks and wear ties or ribbons in their own way to stand out from the rest, according to their personality.
  • Cutting the Knot: In Chapter 71, Lightning gives Ryuji a Secret Test of Character that ends up calling out the Impure Baron, who he could have easily have gotten rid of by tearing the summoning card. He also points out that he could have exorcised the demon reader card rather than playing along with it in the first place.
  • Dark Is Not Evil: Aside from the protagonist, there are plenty of "demons" around that simply want to exist and not bother anyone. Kuro is one of these.
  • Dark Lord on Life Support: Lucifer. It seems to be a lesser version of the same thing that plagues his father, Satan; he's too powerful for a human body that it decays around him with every use of power.
  • Dark Secret: Until Blue Night, Section 13 attempted to mass-produced clones of the demon kings.
  • Demonic Possession: Any demon's only way into Assiah.
    • Happens to Shiro Fujimoto. He is possessed by Satan until he kills himself to save Rin.
    • Happens to Konekomaru Miwa by Gale and Yukio by Satan in the anime.
    • Izumo's mother became possessed by the Nine-Tailed Fox as a result of her depression.
  • Demon Lords and Archdevils: The Eight Demon Kings of Gehenna who are also known as the Baal. There are also the Three Emperors of the True Cross Order, which includes one of the Eight Kings, Azazel the King of Spirits, as a member.
  • Demon Slaying: The exorcists.
  • Devil, but No God: We have seen demons and Satan is the very real enemy of humanity, but no holy beings have been seen yet within the setting. However, Bible verses can be used to banish demons, and holy objects can be used as weapons, so it is ambiguous.
    • Recited Christian scriptures assume there is a god. Recited Buddhist scriptures assume there was Buddha. Maybe it's all a matter of faith and all religions are true?
    • If Satan is the Ultimate Evil in the underworld, could there be a Uber-God who is the ultimate good?
      • Turns out, he's not the Ultimate Evil, he's the Ultimate Being, who just so happens to be evil today.
    • One anime episode has the cast baking a birthday cake for a classmate. Rin accidentally bakes a Christmas cake first. When the class realizes the mistake, they drop it off at Mephisto's office for him to eat instead, at which point he gleefully hangs a lampshade on the whole absurd situation.
    • Some demons are ambivalent or even benevolent towards humans, and most "holy objects" are artifacts related to them. Holy water is produced from one of the demonic founders of the True Cross Order, Armumahel. And this Satan isn't the one from the Bible, he is avatar of Gehenna itself, who gained body and consciosness by accidentally hijacking one of Lucifer's cloned bodies. Lucifer calls him the only God, and he names himself Satan after reading some religious materials. It's not yet revealed how exactly do holy verses work, but Lightning knows how to create new ones, which makes them somewhat similar to spells (after all, he's not very fit to count as saint, so that his words could become new prayer). In short, while using Christian terminology, these 'demons' and 'Gehenna' are more akin to paganistic or Eastern spirits and spiritual world, where there's no intrinsic difference and clear line between good, neutral, evil and just selfish entities.
  • Digging Yourself Deeper: When Rin's friends learn that he is the son of Satan, he tries to tell Shiemi that he's basically a normal human just like her, right as his demonic tail whips in front of him. He grabs it in frustration and admits he's not being very convincing.
  • Driven to Suicide: After Learning that his adopted father was an experimental body for a demon but otherwise learning nothing that he was looking for, and then hurting Shiemi after she tries to comfort him and brings up Rin, Yukio runs out and shoots himself. However, his demonic heritage flares up and saves him.
  • Dying as Yourself: Izumo's mother returns to how she used to be after taking the Nine-Tails back so it dies with her rather than possess her daughter.
  • Dying Moment of Awesome: Fujimoto's final scene, as pointed out in the second chapter:
    Yukio: What were his final moments like?
    Rin: He was awesome.
  • Early-Bird Cameo: A chibified version of Mephisto appears on the front of Yukio's first-aid box in episode 1 of the anime, prior to his formal introduction.
  • Early Installment Weirdness: A minor example, but the True Cross Academy blazers start out being dark green (as you can see in the page image at the top), but quickly become black.
  • Elaborate University High: True Cross Academy owns this trope and takes this Up to Eleven, since it also has an amusement park, a freaking town based around it and lots of secret passages due to being an important base for the True Cross Order in Japan. And everything is BIIIIIG! Possibly Justified as Mephisto is the headmaster.
  • Elemental Powers: According to the Demon Elements there are five elements:
    • Ignis (Fire): Weak to Water and Strong against Decay
    • Urere (Decay): Weak to Fire and Strong against Air
    • Aer (Air): Weak to Decay and Strong against Earth
    • Humus (Earth): Weak to Air and Strong against Water
    • Aqua (Water): Weak to Earth and Strong against Fire
    • There are Eight Demon Kings as well, most falling under the above elements, except for Beelzebub (Insect), Azazel (Spirit), Samael (Time/Space), and Lucifer (Light). They also seem to qualify as elements and Azazel might be the King of Air as much as Spirits.
  • Energy Absorption: If one uses an elemental attack on a demon of the same element, if the attack is not strong enough the demon will absorb it.
  • Everyone Knew Already: Mephisto being a demon and one of Satan's sons.
  • Eye-Obscuring Hat: Donned by Lewin Light (a.k.a. Lightning)
  • Face–Heel Turn: Ryuji's serpent-wielding relative, who cannot stand that the exorcists are allowing the son of Satan to live.
  • Face of a Thug: Rin and Ryuji. Ryuji's father was said to have one as well.
  • Fake Defector: Renzou Shima is revealed to have joined the Illuminati on the True Cross Academy's orders and begins screwing over the protagonists in Chapter 48. Then it turns out the enemy knew all along and he's forced back to the Academy to be stuck in the middle of the two powers to be used by both of them. And all this after the entire team was pretty much emotionally smashed to pieces...and he tries to pretend nothing changed and all is good. They don't take it well.
  • Familiar: Tamer class exorcists have them. Rin acquires Kuro, a Cait Sith, Shiemi has Nii-chan, a Greenman, while Izumo has two Byakko.
    • Arthur Angel's sword talks to him just prior to battles, usually an admonishment about how he's working too hard.
    • Shima has one much to the surprise of Izumo, not to mention the audience. Not only is Yamantaka an incredibly powerful High-Level-Myo-O Demon, but according to Shima it's been his familiar since he was a child. Later information reveals it is bound to the Shima family in some special way.
  • Fan Boy: Played straight with Gedouin to Lucifer, complete with sparkles and delusional fantasies. Lucifer seems to ignore this.
  • Fangs Are Evil: The demons have these, along with Pointy Ears.
  • Fantastic Racism: When Rin's friends find out he's the son of Satan, things get... awkward.]]
    • This trope is subverted in that it's not the fact that he is part demon that they hate. It's that he's part Satan that gets to them.
    • Subverted again, at least in the matter of Ryuji. Turns out most of his anger has to do with Rin deciding to shoulder such a burden secretly by himself, something that Ryuji has complained about before.
      • Also subverted with Izumo and Shiemi. Izumo didn't really give a damn about it , while Shiemi was more hurt by the fact that Rin, her first friend, didn't tell her something so important. Shiemi, being the Fragile Flower she is, took it a little too personally..
      • Subverted as well with Shima who, while definitely being freaked out by Rin being the Son of Satan thing, was more worried about how troublesome being around Rin would be. After the two ate dinner together Shima realized that Rin was a genuinely good person and that it would "be more troublesome trying to avoid him".
    • Played completely straight and justified in Konekomaru's case though. His entire family was killed on the Blue Night and having as much resentment against Rin as he did was only to be expected, and when he finally gets over it, the Friendship Moment between the two is pretty friggin heartwarming.
    • While most of the examples of this trope are subverted as listed above, the anime adaptation plays this trope completely straight once Rin's friends find out.
    • Angel and Neuhaus play this trope completely straight - while other exorcists don't mind demons that aren't actively hostile or harmful towards humans, Angel hates demons in general and never has anything nice to say to Mephisto or Rin despite their fight against Satan while Neuhaus hates anything related to Satan due to losing his family and eye in the Blue Night.
  • Fantastic Rank System: The Exorcists have one. See the trope page for details.
  • A Father to His Men: Ryuji's dad. Whose name, for the record, is Suguro Tatsuma.
  • Fireball Eyeballs: Rin and Satan have these in various color pages. In Chapter 30, when Yukio was about to be killed by Toudou, he got these for a few pages.
  • Flaming Sword: Kurikara, since it currently contains Rin's blue flames.
  • Foolish Sibling, Responsible Sibling:
    Shiemi: You look like the older one!
    Yukio: Yes, it is easy to mistake.
    Rin: [twitches]
  • Foreshadowing: At one point, Yukio is trying everything he can to awaken his demon gene, doing stuff like nearly drowning himself and throwing himself off a tall building (which works momentarily). He nearly shoots himself in the head moments after before getting stopped by a phone call. Mephisto tells him to cut it out, and we don't know if his last attempt would have worked. That is until he attempts to seriously kill himself with his gun and which point his demonic gene does activate.
    • Near the beginning of the story when all the characters are still fresh students and testing their aptitude for demon summoning, Bon and Konekomaru both say they can't naturally summon anything while holding summoning paper. They turn to Shima, not holding any paper, who simply smiles and shrugs. It turns out he can naturally summon a high level fire familiar without even needing summoning paper, which he hides until he reveals his role as a double agent for the Illuminati.
    • Early on while Yukio and Shura are talking during their competition in the batting cage, Shura talks about how suppressing your anger and negative emotions is a bad trait for an exorcist to have as it makes them more vulnerable possession. Ironically, she says Rin makes for good exorcist material in that regard, as much later in the story after Rin's sword is broken and his demon heart returns to his body, he becomes possessed by a manifestation of all his suppressed anger.
  • Funny Background Event: While Bon and Shima are talking to each other right after Rin destroyed the Impure King, Rin is giving Konekomaru a somewhat vigorous head rub with Konekomaru telling him it doesn't feel good and to stop.
  • Gainaxing: Shiemi in the anime while wearing the True Cross Academy uniform. The guys don't miss seeing it at all.
  • Gecko Ending: Around episode 15 the anime splits from its source material to make an original storyline so the season could have a proper "ending", since it Overtook the Manga. As of the second anime, all of that is ignored, however.
  • Get a Hold of Yourself, Man!: Ryuji finds himself doing this (nonviolently) for Konekomaru who just had his Berserk Button pushed by Takara.
  • Good Thing You Can Heal: Angel chops Rin's foot off to control him during his "trial", knowing he'll be fine. Shura and even the online translator are disgusted.
  • Gratuitous Foreign Language: Gratuitous Polish in Episode 20: "Nie popuszcz... takiego, powi...zanego z Szatanem". Not only is it written incorrectly, but also one of characters translates it as "Satan's kin must die"(lit. "Potomek szatana musi umrze...")
  • Gratuitous German: Aside from Mephisto's Eins Zwei Drei, the manga has now "Das stärkste Gefängnis".
  • Half-Human Hybrid:
    • Rin of course. Although, apparently, there's a lot of demon-blooded exorcists. Yukio himself is one but his powers are dormant.
    • The Grigori have Nephilim descendants. Said descendants are the ones running the True Cross Order and acting in place of the three Emperors. Azazels bloodline is known to have died out generations ago.
  • Harmful Healing: How Yukio exploits a Zombie Chimera's healing factor. It absorbs whatever is around it as it regenerates so he kept shooting it down to the ground so that it tried to absorb the alloy. It pinned itself to the floor permanently.
  • Hero Insurance: Referenced in ch68 when Yukio says the Order will pay for the damages, suggesting there is something of this set up for exorcists in case things get particularly messy.
  • He Who Fights Monsters: The trope-naming passage is quoted in reference to Rin and Yukio. Further noted that this is a problem for most Exorcists who could become demons because of their inner hatred or repressed feelings.
  • High School: True Cross Academy is a rather grand one, looking rather like a giant castle. It's also secretly the Japanese headquarters for the Exorcists, though most of the students at the school are completely unaffiliated with them, most not even being aware of the existence of demons. Interestingly, we rarely see any of the actual school going ons, the majority of the time shown is just the exorcist "cram school" class.
  • Holy Burns Evil: Holy water does this to demons. It hurts Rin as well since he's a half demon, but not as much.
  • Hot for Student: Yukio to Shiemi. Though really they're about the same age.
  • Humans Are Special: Why Mephisto's on the Exorcists' side: "The shameless greed the Japanese have for entertainment is spellbinding!! [...] The imaginations and creations of human beings have as much potential as the magical powers of demons..."
  • Hypocritical Humour: Mephisto, in Episode 6.
    Rin: But why the hell does a school cafeteria need first-class food?
    Mephisto: Food is culture! Experiencing the highest-end food will make your lives fuller! [opens a cup of instant ramen and eats it]
    • But then again, there is a bit of Fridge Brilliance in that. Mephisto is actually more than 200 years old and, knowing his love of culture, has probably already experienced all of the "highest-end food." Now he just wants to sit back and eat ramen. Nothing hypocritical about that. Pre-Fridge Brilliance, the scene is still an example though.
  • I Am a Monster: Rin says a variation of this in Episode 9.
    Rin: My wounds have always healed quickly. And now I really am a monster.
    • And then word for word in Chapter 26 before Rin and Shiemi make up.
  • Idiot Ball: Rin grabs hold of it in the anime when at one point Konekomaru gets possessed by a demon. He chases after Konekomaru with his sword drawn, and when stopped by the others, instead of explaining himself, he just shoots his fire at the demon when it reappears and almost burns Konekomaru, which doesn't raise the others already currently low trust in him.
  • I Have Many Names: "Mephisto" is just the latest, he's also been called Loki, Raven, and plain ol' Trickster.
  • The Illuminati: Are responsible for creating a Gate to Gehenna.
  • Imagine Spot: Gedouin has a little fantasy about Lucifer hugging a much better looking version of him.
  • Japanese Christian: Implied that Rin and Yukio are this since they grew up in a monastery (one staffed with exorcists), and there are plenty of bible-verse-slinging exorcists around.
  • Katanas Are Just Better: Justified in Rin's case, as said katana seals his demon powers it's also his demon heart.
  • Kick the Dog: In Episode 2, Satan possesses Rin's adoptive father (which has some unsettling side-effects) and promptly tosses the terrified kid into the gate to Gehenna.
  • Lawful Stupid: In the anime, Angel tries to kill Rin right after the kid saved the day by defeating Amaimon.
    • In Episode 20, Angel also stops Mephisto (with a firetruck) from saving several student hostages because he's under suspicion for performing acts forbidden by the Vatican. What, the moron couldn't give him another minute?
  • Light Is Not Good: Arthur, the current paladin, exemplifies this trope. He even uses Light-based powers.
    • And now the Demon King of Light has shown up; as the current Big Bad.
  • Limp and Livid: Satan in Fujimoto's body, especially when he unleashes his disconcerting Evil Laugh.
  • Love Triangle: Both Rin and Yukio have a crush on Shiemi. Shiemi is completely unaware of this, though she cares for both of them greatly. And in the end she isn't even looking for romance for the time being, so for now neither of them win.
    • Izumo has a pretty obvious crush on Rin...who, so far, only notices Shiemi.
  • Luke, I Am Your Father: Mephisto revealed to Rin that he and Amaimon are also sons of Satan (second and sixth, respectively).
  • Make Them Rot: Astaroth, the King of Rot, and his kin. He has yet to make an appearance himself (except in the anime, where he posses the bully in episode 1 instead of the nameless demon from the manga) but his "pet", the Impure King, was a major antagonist.
  • Marshmallow Hell: A half-example. In Chapter 10 Shura clutches Rin's head under her arm, giving him a faceful of her left boob. The other male students were envious. Strangely though, Rin doesn't really react.
  • Meaningful Name: The new Paladin is called Arthur Angel. Averted, as he mocks Shura and cuts off Rin's foot in trial.
    • Shura means 'carnage/bloodshed'. She got that name from Shiro for attacking a lot of animals and people with a sword when she was a child.
    • Mamushi means 'pit viper' in Japanese.
    • Konekomaru's name can be translated to "circle of kittens".
    • Rin, when written in kanji, can be read as phosphorus, an igniting compound in chemistry. In turn, phosphorus comes from the Greek word "light-bearer" and light-bearer is another term used to describe the fallen angel Lucifer.
    • Subverted with Shima. His given name, Renzou, can mean "pure" or "honest". Shima is, of course, known better for his perverted antics and being a liar.
  • Mega Neko: Kuro, Rin's demonically adorable familiar. In Sleep-Mode Size he's a Head Pet.
  • Miko: Izumo is quite proud of her heritage as a shrine maiden.
  • Mistaken for Gay: When Rin and Yukio stay at an old inn in a town in the middle of nowhere, the old lady running the inn assumes they are a gay couple coming for a hook up. While she seems perfectly accepting of it, Yukio is not amused. Rin doesn't even catch the implication though.
  • More Hero Than Thou: What the other students think Rin is playing up when he appears to be taking unnecessary risks by fighting alone ("Don't forget you have friends!") when he's actually hiding his demonic powers, especially from the guy who has a blood feud against Satan. Having everyone think that he either doesn't trust them or that he's being a glory-hound is really annoying to Rin.
  • Mr. Fanservice: Rin and Yukio.
  • Ms. Fanservice: Shura's everyday appearance in a nutshell. Hilariously, Kato deliberately invoked it...but isn't sure if she did well (ie she just made sure she showed a lot of skin).
  • Multicolored Hair: Shura, she has red hair that ends in bright yellow.
  • Multi-Denominational Team: In addition to Catholic priests, there are Buddhist monks and Shinto mikos. Shiemi could count as a shaman/apothecary.
  • Mundane Made Awesome: The cooking battle between Rin and Ukobach in the anime.
  • My God, What Have I Done?: During the Impure King arc, Shiemi goes through this when it hits her that she and everyone else abandoned Rin in his time of emotional need. It's not until he's literally questioning whether he should even be alive as the Order's higher ups plan to execute him, that she realizes what she's done.
  • Myth Arc: Not one single chapter goes by, not even mainly breather episodes like ch40 and ch68 without the plot moving forward in one way or another. And not just the current plot, but the overall plot has been moving forward since the first chapter and early chapters even foreshadow later arcs. A good example is during ch5, when Ryuji confronts Izumo, we get a quick flash of a woman that looks a lot like her looking very deranged, with Izumo staring up in horror at her with a small girl that also looks like her on her lap. It takes until the Inari arc, about forty-five chapters later to find out what that was about.
  • Names to Run Away from Really Fast: Mephisto Pheles. What does that sound like?
  • No Eye in Magic: Konekomaru pulls this off quite nicely in chapter 43 by taking off his glasses so the demon couldn't make him see his fear.
  • No One Gets Left Behind: Rin is very insistent about this, refusing to leave Izumo behind in the Illuminati arc, even when he is flat-out told to do so by her. He's also the same with Renzo along with Ryuji. Even at the end, Ryuji intends to keep going after Renzo until he a) brings him back or b) gets a proper answer out of him.
  • Not So Different: The fifth episode/fourth chapter has Ryuji's friends remarking that he and Rin are quite similar in overall attitude, despite their differences in terms of grades. Even their prime motivation of defeating Satan overlap, which brings them into further conflict. However, it eventually turns out they are Not So Similar after all.
  • Occult Blue Eyes: Rin Okumura has these (does fit the demonic type, being the son of Satan and all).
    • And then his sibling Yukio got them for a few pages after nearly getting killed by Toudou. Toudou goes as far to say "those are not your eyes".
    • In the manga it seems all of Satan's children are born with blue eyes, see Adaptation Dye-Job for Mephisto. Rin and Yukio are just notable for sometimes having their blue eyes change to look identical to those of Satan himself.
  • Older Than They Look: Toudou got younger after "swallowing" Karura. He started out as a middle-aged man and currently looks about eighteen.
    • Mephisto and presumably Amaimon.
    • Shura is in her late twenties, but looks much younger. This is intentional on part of her pact with Hachiro.
  • Oneesama: Houjou Mamushi to her sibs.
  • The Only One Allowed to Defeat You: Lucifer outright refuses to allow Yukio or Rin come to harm at first because Rin is for their father to defeat.
  • Otaku: Mephisto. His room makes Yubaba's baby's nursery look like a bare cell.
  • Our Demons Are Different: The humanoid ones have elf ears and tails. The other ones range from foxes, ghoulish-sewn-together-bodies, cats, plant... things, anthropomorphic phoenixes, and giant fungus buildings.
  • Our Zombies Are Different: Zombies differ from Ghouls in that they are living humans being parasited on by demons, craving flesh and requiring Head Shots to kill. And even then they somehow became immortal due to all the experimenting with Tamamo.
  • Parents as People: A recurring theme; Shiemi's mother, Suguro Tatsuma, the Shima family, Izumo's mother, and even Shiro are shown as people as much as parents and how they are both plays a part in how their kids turned out and thus current events.
  • Pimp Duds: Mephisto Pheles.
  • Playing with Fire: Rin's flame and other fire demons.
  • Power Limiter: Rin's katana is a limiter to his demonic power. When sheathed the only things that remain are slightly pointy ears and a tail. When he takes it out—all hell breaks loose around him. Quite literally.
    • All powerful demons seem to try to have this in place, or at least when they come to Assiah so they don't damage or destroy their hosts, since they need to hide their "Demon Heart" which acts as both their major weak point and what lets them access their true form and all of their powers.
  • Possession Burnout: Anyone possessed by Satan. Later revealed that all his children the Demon Kings cause a similar effect, albeit not as rapidly.
  • Posthumous Character: Fujimoto Shiro, who adopted and raised Rin, is later developed to be, not only in the church of badass preachers, but THE Badass Preacher.
  • Primal Stance: Rin in his first confrontation with Amaimon.
  • Powers via Possession: Konekomaru gains these briefly when he is possessed by Gale in Episode 17.
  • Rant-Inducing Slight: Takara draws this response from, of all people, Konekomaru when he reveals that he is actually a prodigy exorcist, and a second year at that.
  • "The Reason You Suck" Speech: Konekomaru soundfully delivers this to EVERY SINGLE ONE of his classmates, in the middle of a battle, no less.
  • Reptiles Are Abhorrent: The Hojo family has snake tattoos to go with their serpent familiars, not to mention Hellish Pupils. And the daughters certainly act like a bunch of smug snakes to the other members of Myoo Dharani. One of them turns traitor. But this is a subversion, as she was doing so in response to the perceived threat of Mephisto concealing the Eyes of the Impure King and keeping the son of Satan alive.
    • Amaimon also has an alternate, more demonic form which has some lizard aspects to it when he unleashes his true power.
    • Hachiro, who is both a hydra dragon god and willing to use Mind Manipulation to get Shura to give him a heir.
  • Restraining Bolt: The ring on Rin's tail seems to serve as one: when Shura begins to recite certain verses, it quickly drains him of his power.
  • Revenge by Proxy:
    • Neuhaus, a survivor of the "Blue Night" in which Satan went on a killing spree, took it upon himself to try to kill Rin, the son of Satan.
    • Konekomaru attempted to do this to Rin in the anime while he is possessed by Gale in order to avenge his parents. Ultimately, though, he realizes that killing Rin won't bring back his parents, so he gives it up.
  • Rule 63: Kato Kazue, the creator, posted on Twitter sketches she made of the main cast gender swapped.
  • School Club Front: The Exorcists train the students exorcists in the academy under the guise of a "Cram-Class".
  • Screw the Rules, I'm Doing What's Right!: Ryuji's dad, in a flashback, helped Fujimoto escape with the Koumaken despite the law that all intruders to the sect who know about the Koumaken must be killed.
    • Also when Shura orders Rin's classmates to break him out of prison despite the Vatican's decision to execute Rin.
  • Sealed Evil in a Can: The Eyes of the Impure King, an ancient demon so powerful that just these two eyeballs expel a flood of miasma.
    • The Myou Dha sect used itself to seal the Impure King, so the Myou Dha was the can.
    • At one point, there was a flame demon, Kurara, sealed in Koumaken. It's since left. Koumaken's still a Can, since it contains Rin's demon powers.
    • And then Kurara set up a partnership with Suguro Tatsuma. Finally Toudou, now a major villain, has forced it to possess him, making him much more powerful. Prettier, too.
  • Ship Tease: A little, perhaps with a dash of Foe Yay, with Mephisto and Shura in the manga. When Shura tries to interrogate him, it at first looks like she's flirting with him, and then she goes ahead and straddles him. He calls the view of her chest "a nice view" and eventually tells her that "it would be a pity if a beautiful woman like [her] died at such a young age." And, when she backs off and leaves the room, he muses, "how lovely" in a rather ambiguous fashion. She then concludes that Mephisto will protect Rin from execution. Yeah. Theirs is an odd relationship...
  • Shoot the Hostage: When Shiemi is drained by a pansy demon, it uses her body as a shield. Yukio pulls out his gun, and the demon taunts he wouldn't shoot Shiemi. He does. The pansy demon freaks out and flees. Rin is reasonably pissed off, but Shiemi is fine in the end. Yukio reveals to Rin that he used red dye bullets, having no intention of harming Shiemi at all.
  • Short-Range Guy, Long-Range Guy: The Okumura twins. The Hot-Blooded Rin uses a katana, while his calmer brother Yukio prefers guns. Ultimately subverted though, considering the fact they rarely, if ever, fight together. And when it does happen, Yukio does his best to stop Rin from "interfering". Only in ch3 has it been truly played straight, if briefly.
  • Shotguns Are Just Better: Rin's dad uses one in episode two. To fight a hoard of demons. And does pretty well.
  • Shout-Out:
  • The Short Guy with Glasses: Konekomaru to a T.
  • Shut Up, Hannibal!!: Rin finally shuts Gedouin up with a punch to the face.
  • Spell My Name with an "S": It been stated by the creator that The Paladin's middle initial is 'A' not 'O' like some fans has believed.
  • Stab the Scorpion: When confronted by his human brother about his existence, Rin draws his sword and charges... to kill a demon behind him. "I am not low enough to fight my own brother."
  • Standard Female Grab Area: This trope is pulled on Shura of all people, when Arthur Angel grabs her by the wrist from behind while they are fighting. A bit justified considering the wrist he was holding was connected to her sword hand and he had his own sword against her neck.
  • The Strategist: Konekomaru
  • Super Strength: How about headbutting a giant cat-demon into submission?
  • Stripperific: Shura could count as this. Kind of justified because she needs to have free access to her tattoos when she has to take something from their dimensional pockets... but not much.
  • Soul Jar: Rin's sword is also his "demon heart".
  • Take a Third Option: Subverted initially when Rin first meets Mephisto. He offers that Rin either kill or be killed, and later jokingly adds that Rin could always kill himself too. Rin declines, and demands to be an Exorcist instead.
    Mephisto: The way I see it, you have two options. You can either be killed by us, or you can kill us and run away. Or, of course, you could just kill yourself, and save us the trouble, so that's three options you have. So, which one do you choose?
    Rin: Make me one of you. Make me an Exorcist.
    Mephisto: Okay. Let's say that Satan's son could be an Exorcist. What would you do?
  • Tastes Like Friendship: How Shirou (and later Rin) tamed Kuro—with special wine.
  • Tears of Blood: It happens to the people Satan tries to possess, especially on the Blue Night sixteen years ago. And it happens to Rin's dad.
    • This also happens to Lucifer in Chapter 56 when he strains himself too much.
  • Technicolor Fire: The main character wields vivid blue fire, which in the series is the trademark of Satan. The title represents this, of course.
  • Thanks for the Mammary: Beach kid accidentally does this to Izumi in Episode 11.
  • Time Master: Mephisto: "I am second in Gehenna's hierarchy, The King of Time, Samael."
  • Time Stands Still: When faced with an expanding artificially created Gehenna Gate, Mephisto stops time around it, but notes it won't last indefinitely. They have only bought a few months to fix the problem.
  • Title Drop: From Chapter 33, summing up Rin's mission after he's demonstrated it by defeating the Impure King and annihilating all its insidious spores more or less by himself:
    Mephisto: It's the birth of a blue exorcist... whose self-imposed fate is to kill his own comrades.
  • True Companions: Rin and his classmates. more so after they discover his secret, although in the manga it takes some time for them to get over it.
  • Tsundere: Kamiki Izumo.
    • Rin is a milder male version.
    • Suguro Ryuji is too, but only towards Rin, who he can't stand and has a hard time showing gratitude for honestly. He's relatively nice to everyone else.
  • Turn the Other Cheek: Rin's response to Neuhaus stabbing him in the gut? Offer him as many free hits as he wants while begging him not to harm innocents. It helps that Rin can heal.
  • Un-Paused: In the manga the cuckoo clock Mephisto made during Amaimon and Rin's second fight just kept Amaimon trapped in a pocket dimension where Time Stands Still (since his Healing Factor was paused as well based on his burns) when Mephisto uses it to summon him to Curb Stomp Rin it's clear Amaimon is under the impression that they are still in the middle of that fight.
  • Use Your Head: This is step one for Rin in regards to calming down Kuro. Yukio has the appropriate reaction to this.
  • The Unmasqued World: With the opening of the artificial gate in Chapter 95, everyone the world over can see demons and spirits.
  • Unusually Uninteresting Sight: Nobody is concerned about Rin's fangs or ears (and sometimes even his tail!). Word of God is that it is "surprisingly complicated", and seems to rely on them failing a spot check (if one ditches the chuff of Mephisto's rant on this point). Even exorcists aren't bothered, as there's a number of half-demons and even demons (like Mephisto) who are exorcists. Subverted with Rin's blue flames, since a) blue flames are Satan's signature power and b) can only be seen with those with a masho.
  • Weaksauce Weakness: Rin's tail and his sword are direct connections to his "demon heart". Notice that we've never seen Mephisto and Amaimon's tails.
    • As of Chapter 39, we finally get to see Amaimon's tail. Unfortunately for Rin, he doesn't get to take advantage of it in a fight.
    • Then Chapter 49 brings with it the introduction of Lucifer, the King of Light, leader of the Illuminati, and a Demon King strong enough, even when weakened, to ward off Mephisto. He makes absolutely no effort to hide his tail.
  • Wham Episode:
    • Chapter 48. Shima is revealed to be an Illuminati spy as he successfully captures his target - Izumo.
    • Chapters 93-98 are one prolonged Wham Episode. After every lead to learn about his and Rin's past lead to nothing (and he learns that the Order of the True Cross did cloning experiments to help the Demon Kings, he yells at and physically pushes Shiemi who is trying to comfort him, runs away, and then shoots himself in the head. This causes his demon gene to activate and save him, and he hears Satan taunt him for what he did. After this, he goes straight to Mephisto for answers. When Mephisto flat out refuses to give him any, he threatens to shoot Mephisto as Mephisto goes out onto a stage to give a broadcasted speech to the world about how Demons are real. Mephisto then gets shot in the head by someone unknown, though the guards assume Yukio did it and arrest him. As Mephisto is currently using most of his power to hold back the artificial Gehenna Gate in Russia, he is unable to instantly heal himself like normal. He is forced to withdraw his power back to himself so he doesn't die of his wounds, but this causes the gate to open, spewing forth many demons. Rin learns that Yukio has been arrested and with the help of his fellow exwires, he breaks Yukio out of jail. However, when they get outside, Yukio decides to defect to the Illuminati. Rin tries to stop him from leaving, but Yukio shoots Rin in the face with real bullets. In a blind rage induced from the fact that his own brother shot him for real (previous times were with fake bullets to fool someone), Rin attacks Yukio with the Koma sword, but it breaks in two when Yukio blocks it with his newly gained satanic powers. Yukio and Shima (who chooses to come with him) board an Illuminati helicopter. Since the Koma sword was broken, Rin's demon heart that was housed inside it returns to his body, and he is incinerated by the unconstrained flames of Satan. His body reforms moments later, but it is possessed by Rin's negative emotions. Though he is able to regain control of his body, his demon heart is floating outside his chest, his hair has turned white, and he now has bumps that look like horns sticking out of his forehead. Wow.
  • Wham Shot:
    • During Kyoto a close up of Yukio's eyes reveals they have turned demonic, exactly like his brother.
    • Paired with a Wham Line we have Renzo holding Izumo, who he knocked out, as Takara labels him the spy.
    • At the end of ch80 it is revealed the Illuminati have been collecting various immortal demons and there is a lot of them.
    • Multiple in chapter 93. To wit, Yukio hugging Shiemi, Yukio pushing Shiemi, Yukio shooting himself, and the bullet disintegrating while Yukio's eyes turning blue and Satan mocks him for trying to kill himself. Honorable mention goes to Rin's horrified expression when Shiemi bursts in crying and says something happened with Yukio.
    • At the end of chapter 96, Yukio shoots Rin in the face. With a real bullet this time.
    • Near the end of the chapter, we see Rin's face beginning to degrade and rot from having all his demonic power return to his body, similar to Mephisto and Lucifer's bodies.
  • What the Hell, Hero?:
    • "Why the hell is Satan's kid at our school!? ...No, not Yukio."
    • Also, the online translator is shocked that Angel chopped Rin's foot off to hold him still during his "trial".
  • Words Can Break My Bones: Most lesser demons have a line in the scriptures that exorcises or binds them, as demonstrated by Suguro Ryuji and the Bible.
  • Zettai Ryouiki: Part of the girl's uniform, but notable on Shiemi, Kamiki, and Shura. Also when the boys cross-dressed to get into a girls' washroom.

Alternative Title(s): Ao No Exorcist
