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. Blue Exorcist
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!
, also known as Ao no Exorcist
, is an action comedy fantasy shonen manga
with Multiple Demographic Appeal
by Katou Kazue.
The story revolves around Okumura Rin, 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 Fujimoto Shirou. 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
While Rin is in total shock and disbelief, Fujimoto Shiro 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 Okumura Yukio
, Moriyama Shiemi
, Kirigakure Shura
, Suguro "Bon" Ryuuji
, Shima Renzou
, Miwa Konekomaru
, Kamiki Izumo
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 Netflicks 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.
This series provides examples of:
- Academy of Adventure: True Cross Academy, with demons showing up on the grounds, mysterious, possibly villainous teachers, and the like.
- Adaptation Expansion: The first half of the anime, before it diverges onto an anime-original story.
- Added Alliterative Appeal: Arthur August(e/o) Angel.
- 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.
- 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. Bon scenes in the anime have these. Rin is a golden tiger, Bon'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.
- Anti Anti Christ: Rin is a good-hearted guy who wants to KICK SATAN'S (read: daddy's) ASS.
- 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 Ryūji (Bon) 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 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 Bon.
- 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?!": Bon in Chapter 28 when told by Rin to ride on the giant Kuro/Blackie.
- 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: The True Cross Academy.
- The Impure/Defilement King (a demon in the Decay domain) takes the form of a giant city.
- 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.
- Break the Haughty: When Izumo's confidence fails, her familiars try to kill her.
- 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.
- Following that conversation, Saburota Toudou refined the speech, saying Yukio had no choice in his career path and he really feels he is just a tool made by his Father to protect Rin, so Yukio must've sometimes hated his Father and brother for pushing this burden onto him. Yukio then admits the guy is right, he hates and loves his brother. But then he says what he hates most of all is his own weaknesses in this matter. All while setting up a counter to trap Toudou.
- Further ramped Up to Eleven when Toudou regenerates gruesomely and taunts Yukio, happily stating Yukio's admitted self-loathing is the first step in becoming a demon. After this guy had identified his insecurity, strangled him, and then been exploded because of him, in the course of less than 15 minutes, Yukio takes this hard.
- When Shima's preparing to leave with his Illuminati cohorts in Chapter 49, he takes a brief moment to thank the others for trusting him for so long before saying farewell. Suguro didn't take it well.
- Gale tries this on Konekomaru. It works for a while, but they get over it.
- 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.
- 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. Bon to his dad. The latter wasn't really called for though.
- 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!
- 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.
- 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.
- Conspicuous CG: The Gehenna Gate and "Messiah" (read: atomic bomb mockup) in the anime.
- 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.
- Custom Uniform:
- Angel has an extremely fancy uniform.
- 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.
- 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.
- 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, at least, before his Big Entrance.
- 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.
- Demon Slaying: The exorcists.
- Devil but No God: But there is a Bible.
- 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?
- 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.
- 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.
- 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 Air and Strong against Earth
- Humus (Earth): Weak to Air and Strong against Water
- Aqua (Water): Weak to Eatrth and Strong against Fire
- 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 of a Thug: Rin and Bon. Bon's father was said to have one as well.
- Mr. Fanservice: Rin and Yukio.
- Face-Heel Turn/Well-Intentioned Extremist: Bon's serpent-wielding relative, who cannot stand that the exorcists are allowing the son of Satan to live.
- Renzou Shima is revealed to have joined the Illuminati before entering True Cross Academy and reveals his true colors in Chapter 48.
- Familiar: Strong exorcists have 'em. Rin acquires Kuro/Blacky, Shiemi has Nii-chan.
- Izumo has, not one, but two of 'em.
- 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.
- 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 Bon. Turns out most of his anger has to do with Rin deciding to shoulder such a burden secretly by himself, something that Bon 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, like the Cram School students, hates any spawn of Satan
- Fantastic Rank System: The Exorcists have one. See the trope page for details.
- A Father to His Men: Bon'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.
- Five-Man Band: The Exorcist Cram Students form this and is almost lampshaded by Konekomaru's advice on how everyone could improve in order to become a better team.
- The Leader: Rin, the headstrong and hotheaded protagonist.
- The Lancer: Bon, the equally headstrong but more level-headed rival for Rin.
- The Smart Guy: Konekomaru,the team strategist and even figured out everyone else's weakness and how they can be overcome.
- The Big Guy: Renzou, who has lot of physical potential that he is wasting and should be trying to be a knight meister instead of an Aria.
- The Chick: Shiemi, the only one capable of calming down a berserk Rin and focuses on protecting or healing her friends instead of fighting.
- Sixth Ranger: Izumo, who tries to keep her distance from the group and would rarely help them without being forced in some way at first.
- 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.
- 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.
- Get a Hold of Yourself Man: Bon finds himself doing this (nonviolently) for Konekomaru who just had his Berserk Button pushed by Takara.
- Good Thing You Can Heal/Healing Factor: 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 German: Aside from Mephisto's Eins Zwei Drei, the manga has now "Das stärkste Gefängnis".
- Gratuitous Polish: "Nie popuszcz... takiego, powi...zanego z Szatanem" in Episode 20. Not only is it written incorrectly, but also one of characters translates it as "Satan's kin must die"(lit. "Potomek szatana musi umrze...")
- Half-Human Hybrid: Rin of course. Although, apparently, there's a lot of demon-blooded exorcists.
- 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.
- 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.
- Holy Burns Evil: Holy water does this to demons. It hurts Rin as well, but not as much.
- Hot for Student: Yukio to Shiemi. Though really they're about the same age.
- Hot Teacher: Yukio, at least to Shiemi.
- 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.
- And then word for word in Chapter 26 before Rin and Shiemi make up.
- 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
- 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.
- 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 (first 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'.
- 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.
- 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.
- 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.
- Ms. Fanservice: Shura's everyday appearance in a nutshell.
- Mundane Made Awesome: The cooking battle between Rin and Ukobach.
- 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.
- 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.
- 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.
- Overtook the Manga: At the time the anime aired, only 30+ chapters of the manga were even out.
- Pimp Duds: Mephisto Pheles.
- Playing with Fire: Rin's flame.
- 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.
- 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: Bon's female cousins have snake tattoos to go with their serpent familiars, not to mention Hellish Pupils. And they certainly act like a bunch of smug snakes to their other relatives. 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.
- 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: Bon'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.
- Shotguns Are Just Better: Rin's dad uses one in episode two. To fight a hoard of demons. And does pretty well.
- Shout-Out: In Episode 19 of the anime, Paku and Izumo go to Magnaria.
- 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?
Rin: KICK SATAN'S ASS!
- Tastes Like Friendship: How Shirou (and later Rin) tamed Blacky—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:
- 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.
- 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 of number 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. Holy SHIT.
- What the Hell, Hero?:
- "Why the hell is Satan's kid at our school!?"
- 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.
