InuYasha is an enormously popular anime based upon the similarly popular manga of the same name by Rumiko Takahashi. Seven seasons totaling 167 episodes were made and shown on Japanese television, with the series ending in September 2004 in Japan. [adult swim] aired the final episode of a very decent English-language dub in October 2006, and the series continues to air in the very early Sunday morning slot, where it has been airing continuously since the series' end (the only other show to have run longer on Adult Swim is Cowboy Bebop). Inu-Yasha and friends appear in the Massive Multiplayer Crossover game, Sunday VS Magazine: Shuuketsu! Choujou Daikessen.Japanese Ordinary Middle School Student Kagome Higurashi, granddaughter of a Shinto priest, has the ability to climb down into an ancient well on the grounds of her grandfather's shrine and, in doing so, Time Travel to allegedly-feudal-Japan; pretty cool, except for the fact that demons, goblins, vengeful ghosts, malevolent wizard-priests, short-tempered twelve-foot-tall ogres, and all manner of other creepy-crawlies are everywhere and you can barely swing your arms without hitting one of them. Significantly, this is one of the few Japanese fantasy anime that isn't set in a pseudo-medieval-European fantasy world; just about everything in it is based on Japanese myths and legends. Another noteworthy difference from most anime is that almost all of the characters who are supposed to be Japanese humans are actually depicted with black hair, instead of other Hair Colors.One of the first characters she meets is the Inuyasha - an obnoxious, abrasive, arrogant half-demon teenage boy with long flowing white hair and super-cute doggy ears on top of his head; his father was apparently a dog-demon with a taste for human women. Inuyasha, needless to say, actually has a heart of gold, though he requires Kagome's insistence to do good deeds. You all knew that was coming, didn't you? Right? Right.Oh, and did we mention that Kagome happens to be the reincarnation of the miko that Inuyasha once loved 50 years in his past, who just happened to be the one who fired a sacred arrow which sealed him to the sacred tree, essentially killing him? Kagome's arrival in the past is pivotal in that she is the one who releases InuYasha from this "death" by pulling the arrow from his chest. Her connection with his past love allows her to perform this otherwise impossible feat.The small-scale structure of the story is episodic, with many a Monster of the Week (usually literally a monster). However, in addition to the romance angle between InuYasha and Kagome, there is an overarching plot about Kagome and her adventuring companions wandering pseudo-medieval-Japan in order to collect the pieces of the shattered Shikon no Tama/Jewel of Four Souls, which eventually turns into a struggle against the Big Bad — the evil incarnate that is Naraku, a human-turned-demon that seeks the Shikon Jewel in order to taint it and become a full-fledged demon with powers far beyond anything any demon has ever known, and whose plotting turns out to be behind just about all of every main character's miseries. Over the course of the series, InuYasha and company confront Naraku several times, but each time he gets away, gaining more shards of the Jewel — and an extra power or two — in the process. Forcing Inuyasha to gain a new power as well just to ward off Naruku's attacks. Rise, rinse, and repeat till it's conclusion.The manga eventually reaches a resolution, but it takes its sweet time to do so (56 books when the main plot would really need only, say, twenty), and the anime was Cut Short with no proper ending due in large part to actually catching up with the production of the manga and running out of episodal stories to do. The remaining chapters of the manga that the anime didn't cover before its abrupt end were adapted into the 26-episode series Inuyasha: The Final Act, which picks up where the original anime left off and tells the remainder of the manga's story through to its conclusion.Viz has posted licensed subtitled versions of both InuYasha and The Final Act on Hulu. The show currently airs on [adult swim]'s Toonami block, taking up the last hour of the block. The crew behind the new Toonami has also noted their interest in airing InuYasha: The Final Act, mentioning it as one of the "many shows we've been looking at". The original, as well as The Final Act, are also currently streaming on Neon Alley.
Twenty-Four-Hour Armor: Sesshoumaru and Kouga never go anywhere without their armor. Given that Inuyasha's fire-rat robe is supposed to double as armour, he never goes anywhere without it either. Sango also keeps hers on hand everywhere she goes, whether or not she's actually wearing it.
There exists a series of parody clips that were made before the abridged craze, and they are probably the most well-known for InuYasha.
There is also ITAS, an Abridged Inuyasha done by ICanadianJutsuI, Scarlotte (ep 1-8), Shallirica (ep 9-present), and Dimensioncr8r (ep 9-present). of YouTube and hosted on the former's channel (which is here and here). Also here. It's quite funny and currently has 10 episodes. The guy who's doing it is on his ELEVENTH YT channel. There's also Inuyasha The Real World. Check it out!
Accidentally Broke The Mac Guffin: Near the beginning of the series Kagome shoots an arrow at a bird carrying the Shikon Jewel, but the arrow hits the Shikon Jewel itself, spreading shards of the Jewel over Warring States Era Japan and setting our heroes on a quest to gather the shards before they land in the hands of evil.
Alas, Poor Villain: Kagura. Her death is quite tragic: she decides to save Kohaku knowing well that neither Akago nor Naraku will be happy with her betrayal. Naraku mockingly returns her heart before fatally poisoning her with his miasma. The heroes and even Sesshomaru rush to try to help her to no avail. She dies in a field of flowers, with a smile in her face for Sesshomaru being there, and her last thought being “I am the wind, as free as the wind.”
Alleged Lookalikes: Everyone initially compares Kagome to Kikyo. They may technically have the "same" face (as it turns out they have the same soul), but when the series suffers from Only Six Faces and Kikyo and Kagome purposefully differ in hair style, habitual facial expressions, skin tone, and age, they don't look alike at all - at least, not any more alike than any other two random characters you could pick out. The anime has it worse, so that it's almost an Adaptation Induced Plot Hole there.
Amazon Chaser: Sango is wanted by both Miroku and Kuranosuke because of her beauty and her strength.
Amplifier Artifact: The Shikon Jewel is shattered by accident by one of Kagome's arrows. Other demons that get even one or two shards get a comparatively large power boost. Naraku collects all the shards for reassembly into the intact Jewel for the purpose of becoming the ultimate youkai.
Anatomy Of The Soul: The soul is divided in two: Kon and Haku. Kon is the heart (will) and Haku is the power that moves the body:
Moryomaru is just a bunch of dead youkai body parts animated by Haku. When Akago is inside of him, he provides the Kon.
Kikyo's Kon is the part she stole from Kagome's soul but she needs to constantly steal Haku to be able to move.
And Then What?: Near the end, Byakuya asks Naraku what wish he will make on the Shikon Jewel after he has killed Inuyasha and the rest; he admits he isn't sure. Later Kagome correctly guesses that he had already made a wish but the Jewel didn't grant it.
Animation Bump: The anime series itself often goes from good to poor in sequential order, with a superbly animated episode followed by a greatly inferior one
The finale of the Bankotsu fight has smoother animation than most of the series.
The Final Act continues the trend of fluctuating quality, but is overall better than the earlier series. A shorter series with a generous budget means the show basically got the same quality as the earlier movies. Conspicuous CGI was the main offense.
Anti-Hero: Kikyo settles into the role after her resurrection, once the worst of her initial rage has subsided.
Sesshomaru starts off as a villain, but subsequent Character Development shifts him from there to Anti-Villain and from there arguably to Anti-Hero; exactly where he falls tends to vary depending on your perspective.
A case can also be made for Kagura possibly reaching Anti-Hero status by the end of her character arc when she begins acting directly against Naraku - again depending on your mileage.
Anti-Villain: Saint Hakushin; Kagura and Sesshoumaru both evolve into this role as well.
Appendage Assimilation: Sesshoumaru tried to replace his severed arm with other youkai arms, but they all turned out to be useless and after a while he just stopped trying.
Artistic License - Biology: It's a funny notion that a dog-demon is several times stronger than a wolf-demon, when wolves in average are bigger, stronger and more ferocious than dogs, with dogs being naturally afraid of wolves to top it. Best not tell Inuyasha that.
Art Shift: The first three movies have a different character designer from the anime, resulting in this. This is averted for the fourth movie, however.
Artifact of Death: The Shikon no Tama and its search only brings death and destruction.
Yura of the Hair is actually a spirit born from a comb used to comb the hair of dead people. Destroying the comb destroys Yura.
The cursed Noh Mask. It is a deadly artifact that once placed on the face, it absorbs/consumes the wearer.
Later, Sesshomaru commissions the making of the deadly sword Tokijin, crafted from the teeth of Naraku's detachment Goshinki. It possesses its own maker, but when Sesshomaru takes it for himself, he shrugs off the sword's attempt to possess him through sheer willpower.
Kanna has her Mirror, which can steal the very soul of those she shows it to or, in some cases, absorb the power and devastating effect of a weapon and allow her to direct it back at the sender.
The Naginata of Kenkon, aka the Naginata of Heaven and Earth, was fashioned from the corpses of 222 demons by the same demonic smith who made Tokijin.
Dakki, the youki-absorbing sword that transformed its human smith into a pseudo-youkai in order to try and absorb Tessaiga's youki and then transferred the full force of Inu Yasha's attack to said smith's body in a desperate attempt to save itself.
The Movies also introduce a few more, like Kaguya's mirror and the terrible Sou'unga: The Sword of Hell. Sou'unga can not only create the devastation of the dragon vortex, but it can possess its owner and force them to commit murder wherever and whenever possible.
The best example however, would be the Shikon no Tama, the real Big Bad of the story.
Awful Truth: The truth about Tenseiga is kept secret for a long time because it's this trope for Sesshoumaru.
Awesome McCoolname: Sesshoumaru's name is written with kanji meaning "kill," "life" or "genuine," and "perfection," a combination which could be interpreted to mean something to the effect of "perfect killer" or "complete destruction of life."
A number of the attack names also qualify, first among them Meidou Zangetsuha, which means "dark path of the dawn's moon blast".
Ax-Crazy: Evil!Suikotsu, as well as Inuyasha himself whenever he goes in his youkai form.
Babies Ever After: In the manga's finale, Miroku and Sango have gotten married and have three children; twin girls and a baby boy who is born at the start of the final chapter.
Inu Yasha and Koga vs. Naraku's two speedster detachments
Badass: It is almost impossible to not be impressed by some of the characters' exploits in the story, such as Sesshomaru not flinching from having his arm ripped off, Kagome blasting Naraku till only his head remains just because he pissed her off, Naraku eating Moryoumaru from the inside out and later dying with smarmy remarks and a smile at the end of the series, Sango digging herself out of her own grave, Kagura slaying entire army of demon wolves with a couple of wind-blades, Inuyasha defeating the foe his father died fighting, Inuyasha being able to completely break the state of full-demon he became from losing Tessaiga and much more for every character.
Hell, Shippo is something of a badass, when one considers all the things he's done even though he's a little kid, up to and including having to be knocked out to keep from following the team into the final battle against Naraku... and then did it anyway once he regained consciousness. Just look how the much larger kitsune treat Shippo's exploits during the kitsune youjutsu exam that he didn't even know existed until after he was auto-enrolled into it by accident.
Whenever Inuyasha turns human he continues to try the same potentially fatal exploits that wouldn't even bruise him as a half demon, up to and including fighting homicidal demons three times his size. Crosses the line into Determinator territory when he (of course) keeps fighting after massive blood loss and broken bones.
Badass Normal: Sango. She's completely human and the only protagonist who doesn't have any kind of supernatural or magical power, but she's able to throw around the huge boomerang as if it were a toy, and is just about as good of a fighter as Inuyasha himself.
And of course, Kohaku. His Shikon shard doesn't seem to do anything but keep him alive and under Naraku's control, but by the end of the series he's able to easily slaughter groups of trained guards and youkai like they were nothing.
Barrier Warrior: There are several, including Miroku, Kikyo and Naraku, but the most impressive is Saint Hakushin who is able to create an enormous barrier surrounding Mt. Hakurei which is incredibly powerful, enough to weaken youkai in the surrounding area and purifying them instantly if they get too close.
Manten gets extremely upset when his last few hairs are lost from his head.
Sesshoumaru's are mostly related to receiving Inuyasha's pity and hearing Kagura's death being insulted. The latter upset him so much that he broke Tokijin over it and endangered his own life in the process.
Discuss Inuyasha's love for Kikyo around Kagome. I dare you.
Threaten Inuyasha or any of Kagome's friends when she's around, only if you've made your peace with a higher power beforehand.
Big Brother Instinct: Sesshomaru towards Inuyasha increasingly as the storyline progresses, Sango towards her little brother Kohaku, even the evil Hiten towards his younger brother Manten (and their little brothers love them too). Kagura also seems to develop one towards Kohaku, which ultimately led to her dying for it.
Big Entrance: If the main activity suddenly gets interrupted by everyone being drawn to what appears to be a massive bolt of lightning that crashes into the earth, rattling the ground and releasing an overload of raw power, it almost always means Sesshoumaru's just entered the scene.
Blade Brake: Inuyasha rams Tessaiga into the ground to prevent being sucked into the Wind Tunnel. In one of many amusing examples of just how alike the two brothers really are, when Sesshoumaru first experiences the power of the Wind Tunnel, he reacts in exactly the same way (and since he's holding Tessaiga at the time, he even uses the same sword).
Also performed by Kohaku to prevent himself from falling to his death down a chasm.
Also by Kagome with Tetsusaiga inside Naraku's body.
Blessed with Suck / Cursed with Awesome: Miroku. The Wind Tunnel in his right hand, a curse placed on his grandfather and passed down onto him, is basically a one-way dimensional gateway with the force of a minute black hole. Even the most powerful of demons seem to be unable to escape it if drawn inside — witness the spirit of Kaguya, an entity stated to be truly immortal, being banished forever by being drawn inside the Wind Tunnel. However, Miroku can only control it by wrapping his hand in certain special beads, and as Naraku created it, he has also created a counter for it: a rapidly-breeding wasp-like creature called Saimyosho contain a poison that will cause Miroku intense pain and eventually death if he draws them in. Oh, and the Wind Tunnel, even if not used, is slowly growing ever larger, until the day when it consumes Miroku and everything around him in a fair-sized Sphere of Destruction, just as it has already devoured his father and grandfather.
Inu Yasha's youkai form. Insanely high levels of strength and speed, a much improved healing factor, enough youki to make even Sesshoumarufeel one, brief moment of fear and have a youketsu capable of holding the evil spirit of the Shikon no Tama immobile against its will and decay a frggin' portal to hell when its sliced by the Dragon-Scale Tessaiga. Of course, there's the little matter of him being a bloodthirsty monster that has barely any of Inu Yasha's restraint, and each time it gets even less controllable and less intelligent. Of course, he does get to occasionally take advantage of it and Tessaiga at the same time, whenever someone starts stealing some of Tessaiga's forms, or he boosts Tessaiga with purified Shikon shards.
Blood from Every Orifice: This happens to Miroku when he takes a massive dose of Naraku's miasma into his Wind Tunnel in the process of trying to take him out once and for all.
Bloody Murder: Inuyasha's first and most basic ranged attack involves him making flying blades out of his blood (or, sometimes, other people's). He tends to pull it out only as a desperation move, for obvious reasons.
Blow You Away: Kagura. Her wind powers include tornados, flight, manipulating the wind to (attempt to) cut off the wind-based attacks of opponents and even Razor Wind.
Also very noticeable when the living Noh mask attacks Kagome; the body it has is the corpses of its previous victims mashed together into one fleshy lump.
Body of Bodies: The list include the Flesh-eating Mask, Naraku's true form, the whole Kodoku spell and also Moryomaru's later forms.
Boomerang Comeback: Sango uses this technique several times. She lets her enemies attack her while Hiraikotsu is away so they'll be hit by it when is returning to her.
Bowdlerise: First villainess Mistress Centipede's breast size is reduced in the Viz dub. Some scenes that involve Kagome bathing, and one instance of Shippo taking off his clothes for a bath, are also cropped or otherwise edited.
Actually the anime is also a case of Bowdlerise from the manga too. The aforemention Mistress Centipede is NOTBarbie Doll Anatomy at all in the manga. Kagura's chest is also shown very clearly but is pretty much toned down in the anime.
Brainwashed and Crazy: Kohaku. After being revived, Naraku erased his memories to be able to control his mind. He then ordered Kohaku to kill a lot of innocent people, including his own sister.
Cain and Abel: Inuyasha and Sesshoumaru for a while. A better example would be Kinka and Ginka, brothers who are attached to one another because neither of them had managed to kill each other in their childhood as was the nature of their species.
The Call Knows Where You Live: After returning to her time after her first trip to the feudal era, Kagome assumes the whole experience was a dream and proceeds to forget about the whole thing....until Inuyasha barges into her house while her family is having dinner. It doesn't help that one of the bad guys (Yura of the Hair) seeking the Shikon Jewel tries to enter Kagome's time moments later.
Calling Your Attacks: Once the manga hit its stride, almost all the characters do this. Uniquely, Sesshoumaru's the only one who is mostly too cool to call his attacks out loud. He thinks them instead.
Sango: "After all, she's the one you asked to bear your child."
Miroku: "Well, it's something I always say when I meet a girl."
Sango: "You haven't said it to me though."
Miroku: "Forgive me Sango! Will you..."
Sango: "You don't have to say it!"
Cats Are Mean: A rather impressive filler arc showcased some cat demons as this.
Changed My Jumper: Kagome traveling through Feudal Japan in her school uniform with a very short skirt.
Changing Clothes Is a Free Action: Played straight by Sango at least once in the anime where she changes from her normal clothes to her armor in a second, while leaping. Usually she averts it though, either having some time to change, fighting in her kimono or already wearing her armor since the beginning.
Characterization Marches On: Probably what happened to the smiling, talkative Sesshoumaru. Lampshaded briefly in the manga, however. In the early days, his smiles were usually only sadistic. Later on in the manga, once Sesshoumaru's unsmiling, taciturn personality is established, Jaken does briefly observe that Sesshoumaru only smiles when he's in a killing mood.
Chastity Couple: Basically what Miroku and Sango become after the proposal and before their marriage.
Combat Pragmatist: Miroku shows signs of this in his fight with Sango, tripping her with his staff so she'll lose Hiraikotsu. He's reminded painfully she has other weapons.
Combination Attack: The anime made up one for the films and a filler mini-arc involving Kagome's arrows and one of Inuyasha's special attacks combining together for impressive results. This doesn't actually make much sense because Kagome's arrows purify youki which is exactly what Inuyasha's attacks are made of, but it's not something that ever crops up in the manga.
Comedic Sociopathy: Where to begin? Kagome's abuse of Inuyasha, Sango's abuse of Miroku, Inuyasha's abuse of Shippo, Inuyasha and Miroku's abuse of each other, and Sesshomaru's abuse of Jaken are the more regular instances.
Comic Book Time: While the manga lasted for 12 years, the whole story happens in barely one year, not taking into account the three-year Time Skip at the end.
Compressed Adaptation: The last season of the anime, where about 10-20 chapters were compressed into each of 24 episodes.
Conspicuous CGI: Pops up rarely, though the worst case is a scene in The Final Act where the grass was computer animated, and not lighted the same way as the hand-drawn parts.
The Constant: The Sacred Tree and Bone Eater's Well. To the extent that, when the Bone Eater's Well disappears in the Final Battle, it's seen as a very, very bad sign by everyone on both sides of the well.
Cool Clear Water: None of the character seem to worry about how safe the water is to drink unless it's because a dangerous Youkai might be lurking there waiting to pounce on unwary drinkers... despite the story being set during a time of rampant war, death and disease.
Cooldown Hug: In the final episode of the (first) anime, when Inuyasha was turning into full youkai, Kagome's hug stopped the transformation. Justified in that she's in fact purifying the corrupt Shikon shard he was using.
And again in the second movie, under similar circumstances - Inuyasha being forced to turn full youkai by the villain of the week. Except this time it didn't work until she kissed him.
The Corrupter: Naraku (His favorite tactics are those that involve messing with his enemies' hearts).
Crazy-Prepared: Sango habitually carries a backup weapon, a hidden backup backup weapon, and a considerable assortment of poisons designed for use against demons. She rarely ever gets past using Hiraikotsu and her short sword, though.
Creepy Centipedes: Mistress Centipede is the first and foremost instance, but generic giant centipede monsters turn out to be one of the most commonly-encountered and easily-dispatched types of mook.
Cut Short: The anime initially ended just over half-way through the manga and there was nothing more for several years until the manga ended. This was finally subverted when a wrap-up series The Final Act was produced to conclude the anime, although it heavily truncated the story to try and fit over 200 chapters into 26 episodes.
Damaged Soul: Kikyo only has one part of her soul since Kagome has most of it. Which also means that Kagome's soul is missing a piece, but her soul is depicted as so unusually large and potent that it's not enough to notice.
Dark Action Girl: Kagura (starts off this way), Tsubaki, Jakotsu (or so he thinks), Princess Abi, Mistress Centipede, Yura, Kaguya
Dark and Troubled Past: Inuyasha and Miroku. Inuyasha was shunned by humans and hunted by youkai for being a hanyou (his half-brother hate him for that same reason), lost his mother early in his life and spent the rest alone, then he fell in love with Kikyo who betrayed him (or so he thought) and was sealed for fifty years. Miroku witnessed his father fall victim to his curse when he was a little kid, watching him being consumed by his hand only leaving a big crater afterwards, and grew up knowing that that would be his fate one day.
Darkest Hour: Sango and Miroku waiting for the Wind Tunnel to absorb them while their despair consumes the light within the Shikon no Tama leaving it in darkness.
Sesshoumaru's darkest hour occurs when he finally learns the truth about Tenseiga's origins and the real reason why he was given Meidou Zangetsuha, resulting in him believing that his father had been training Inuyasha to kill him. His Heroic BSOD is so overwhelming that even Myouga is desperate to help him. He's left so shaken that when Naraku attacks his group he doesn't even try to rescue them; Inuyasha ends up saving them while he watches from a distance. Nothing in the manga - not even Kagura's death or Rin's second death - has ever made him despair the way thinking his father hated him did.
Inuyasha is tricked into thinking he murdered Kagome in his blood rage. This breaks him down so completely that he gives into his despair and demon blood.
Date Peepers: Every time Inuyasha/Kagome or Miroku/Sango have any romantic moments, the rest of the group will be either spying or eavesdropping.
Death Glare: Sesshoumaru. Early in the manga, he scares off a pack of wolves with his glare alone. Later on, he's badly injured to such an unusual degree that Kagome and Shippou worry about it and discuss healing him. His glare sends both of them scurrying behind Inuyasha for protection.
Death Is Cheap: Ask Kikyo... or Kohaku... or Rin. The series does try not to take it too far: before he could master Tenseiga's Meidou Zangetsuha, Sesshoumaru had to learn that even Tenseiga's ability to revive the dead has its limits, since he couldn't properly appreciate the value of the lives of others as long as he assumed he could simply bring them back. However, the lesson is rather undermined when Sesshoumaru's mother revives Rin a second time anyway.
Distressed Damsel: The anime likes putting the female characters in distress much more than the manga does, especially Kagome and Rin. In the manga, however, Kagome's last true kidnapping was by the hands of the baby. After that she becomes a full-on Action Girl, saves Kikyo's life, defeats Naraku alone while burning in the flames of Hell, gets her ultimate weapon and her last part of Character Development after facing the shadows of her heart before ultimately killing Naraku and the Shikon Jewel. Rin isn't really kidnapped much, given the length of the manga, but the final time she's kidnapped lasts for quite a few chapters since it's the final battle.
Does Not Like Shoes: Boy howdy... It'd be faster to list the characters who do wear shoes or sandals in this. Rumiko Takahashi is pretty well known for her foot fetish, meaning you'll see plenty of her characters barefoot, and plenty of close-ups...
Dojikko: Rare male example: Akitoki Hojou. Also a Dogged Nice Guy towards Kagome, like one of his descendants.
Doom It Yourself: In one of the filler episodes, Inuyasha accidentally damages the handlebar to Kagome's new bicycle. While she goes to school, he volunteers to fix it. Given his lack of knowledge on bicycles - or anything else from the modern era for that matter - things quickly get out of hand, and by the time Kagome gets home, the bike is in even worse shape.
Dumbass Has a Point: Considering how Jaken only sees Rin as a bothersome and clueless kid, this would count when she's the one to point out to him that Kagura is possibly in love with Sesshomaru, something he completely dismisses.
Dynamic Entry: Happens several times. One example consists of Kagome, Miroku and Sango being saved from Mukotsu by a clawed hand slicing into Mukotsu's body signify the arrival of - to Kagome's shock - Sesshoumaru rather than Inuyasha.
Earn Your Happy Ending: After everything the main characters went through, almost all of them got a happy ending. Miroku and Sango are Happily Married and have three kids; Shippo is learning to get better with his powers; Kohaku, accompanied by Kirara, is atoning by helping other people; Rin is staying with Kaede and is often visited by Sesshoumaru; and even though they were separated for three years, Kagome and Inuyasha are reunited at the end.
Eat Me: Naraku lets Moryomaru absorb him so he could get close to Akago and consume both of them from the inside.
Eviler than Thou: Moryomaru's a mean guy but he's just a thug compared to Naraku.
Excalibur in the Rust: In the hands of almost anyone except Inuyasha, Tessaiga looks like a katana that has seen better days. When Inuyasha weilds it, the blade takes its true form.
Exponential Plot Delay: It never ends! It never ends! (Well, until it finally does; the story does progress and characters do develop, just very slowly except for near the beginning and end of the series.)
Expy: Mostly of Ranma 1/2. Rumiko Takahashi herself admitted that the InuKag romance was supposed to be the Ranma/Akane romance as it should have been written. Sango resembles Ukyo Kuonji in terms of design and Miroku looks a lot like Shinnosuke (and like the young Luckyosai, Happosai's "old friend"). Also, Myoga resembles manga-Happosai in looks though not personality. And if you look at it the right way, Koga/Ryoga Hibiki. Bonus points for the fact that Ranma and Inuyasha share voice actors in both Japanese and English (Kappei Yamaguchi and Richard Ian Cox, though only for the latter half of Ranma in Dick's case), and Kelly Sheridan is the English voice for both Ukyo and Sango. Further, David Kaye voices both Soun and Sesshomaru, and Paul Dobson voiced both Happosai and Myoga.
This actually plays into Japanese culture; the beings referred to in Japan as Youkai and Obake would probably be considered more Fey than Demons by Western standards.
Family Theme Naming: The three named characters from the demon slayers' village — Sango, her younger brother Kohaku, and their pet Kirara — all have names referring to semi-precious stones (coral, amber and mica, respectively). Additionally, Kikyou and her younger sister Kaede both have names that begin with K and refer to plants (bellflower and maple). Also Kagome and Souta could be taken to mean Bamboo and young grass respectively.
Fanservice: Kagome does seem in many shots to be almost entirely made up of very shapely legs, though we never seeup her skirt. Twice, Kagome's breasts were bared though this is edited for the American releases as is the short shot of Shippo disrobing for a dip in an onsen. Also, Sango's Taijiya uniform is veryform fitting. All of the main girls have been subject to nude scenes shortly after their introduction. Kagura's top gets ripped off numerous times.
Yakurou Dokusen offers a "medicine" to Miroku so he'll stop feeling pain everytime he sucks poison into his curse but it won't cure the shouki wounds that are killing him. He takes it.
Shikon shards in the body will make it insensitive to pain no matter how severe the injuries are, which is how, for example, Sango manages to go toe-to-toe with Inuyasha in her first appearance despite being grievously injured.
Final Battle: The series' final battle takes place when the Five-Man Band plus Sesshomaru's group go inside Naraku after he transforms into a giant, floating spider.
Fire-Forged Friends: The main group was formed because all the members (except Shippo) share a common goal, and at first they were hostile to each other. Inuyasha and Kagome are forced to work together to find the Shikon shards, they let Miroku join after learning they share a common enemy and Sango joins for the same reason. They warm up to each other and end up being best friends since they don't really have anyone else.
Fire Keeps It Dead: In the first chapter a mortally wounded Kikyo has herself cremated with the Shikon Jewel so she can take it to the afterlife with her and keep it out of the demons' hands. Unfortunately she didn't count on her reincarnation as Kagome five centuries later.
Inuyasha starts to call Kagome by name after defeating Yura. Miroku jumps directly to first name basis with no honorifics with Sango, the only woman he addresses in such a fashion.
Averted by Sango, who never uses Miroku's name at all, always calling him "Houshi-sama" even after she's promised to marry him. (This and Miroku's use of yobisute mentioned above are distinctions not carried over into the English dub due to the difficulty of translating them effectively.)
Follow the Chaos: Naraku, along with his "stink", also tends to leave behind trails of dead bodies everywhere he goes
Foolish Sibling, Responsible Sibling: Plays with this. Kagome isn't flighty per se, but often forgets to bring her homework to class, only for Sota to pick up the slack. Then again, considering she's spending most of her time in the Feudal Era, she can hardly be blamed for losing focus on her supposed off days.
A brilliantly blatant yet easy-to-miss example occurs when Naraku manipulates Sango into stealing Tessaiga for him. He is able to hold it and briefly uses it against her. Amids the ensuing drama, the audience isn't likely to remember that said sword was suppossed to have a demon-repelling barrier around it that should've left a full demon like Naraku with some ugly burns on his hand... this is explained when we learn that Naraku isn't a full demon at all...
Another moment occurs as a result of the same incident. Sango tells Inuyasha's group that they can't trust her because, if Naraku attempts to use the same tactic on her in the future (making her choose between friends and a loved one), she'll make the same decision all over again. Right at the end of the manga, Naraku attempts what Sango feared and does indeed try to repeat the incident. This time, it's a choice between Rin's life and Miroku's life and, as warned, Sango does indeed make the same decision again: attempting to kill Rin to save Miroku.
Another throwaway comment, this time by Toutousai. When Inuyasha first masters the Kaze no Kizu while fighting Sesshoumaru and it's revealed at the same time that Tenseiga has chosen Sesshoumaru as its true master, Toutousai mutters to himself "Whether Tenseiga lives or dies will depend on Sesshoumaru's heart". It takes hindsight to show us just how significant that statement proved to be.
A Quirky Miniboss Squad in one of the late filler arcs (first half of the anime's sixth season) is a squad of four Demon Ninjas based on them; Byakko of the Snow (Byakko the White Tiger), Genbu of the Darkness (Genbu the Black Turtle), Seiryuu of the Moon (Seiryuu the Azure Dragon), and Suzaku of the Flower (Suzaku the Vermillion Phoenix).
The villains of the the fourth movie, "Fire on the Mystic Island", are also based off of The Four Gods, though somewhat less blatantly than the aforementioned Demon Ninjas.
Free Sample Plot Coupon: Downplayed. Kagome already has the Shikon pearl inside her at the start of the series, but after some unsavory events it is fragmented into several pieces, scattered through Feudal Japan. Thus the objective is to retrieve them, and the first of them is held by a very powerful opponent, negating the trope entirely.
Fuel Meter Of Power: The Wind Tunnel is constantly expanding (a process that is accelerated every time it's used and even more so if it's injured) until it's big enough to break the seal and kill Miroku.
Handicapped Badass: Sesshoumaru lost his left arm fighting Inuyasha in his first appearance. He still was one of the most powerful characters in the series. He even got his arm back towards the end in a Crowning Moment of Awesome.
Head Pet: Inverted. When Shippo travels on Kirara, he usually does it on her head.
Healing Factor: Everyone with youkai blood. Sesshoumaru ups this to eleven later on in the series, however, which results in him being able to regenerate his missing left arm.
Healing Shiv: Sesshomaru's sword Tenseiga can revive the dead by cutting down the pallbearers of the afterlife as they come to collect the dead person's soul. However, as is eventually revealed under tragic circumstances, people can be revived in this manner only once.
Hybrid Power: Inuyasha has a lot of demonic power from his father, but his human side has certain advantages of its own. Due to his incredibly powerful father he has more power than many demons, and his human side grants him use of the sword forged from his father's fang, which lets him take out any demons his own powers can't take.
I Choose to Stay: After finishing her education, Kagome opts to remain in the past with Inuyasha.
I Die Free: Kagura only desire is to be free but doesn’t want to die to get it so she does everything in her power to get Naraku killed without him knowing. When she chooses Kohaku’s life before her own and gets impaled by Naraku for her troubles, she realizes that dying was the only way to be free. (Further confirmed by Byakuya who mentions that the detachments would die anyway when Naraku is killed).
I Have Your Wife: Naraku revived and brainwashed Kohaku just to mess with Sango.
Idiot Ball: Shippo in episode 50, unintentionally provokes Inuyasha into using the Tessaiga which was hard to use after being reforged, while for once he was trying to be pragmatic and use his claws against Kagura's weak demons prior to the big slip of the tongue.
I Never Told You My Name: In the Hoshiyomi filler arc, demons manage to get a photo of three of Kagome's friends from her backpack, and use it to create puppets of them in order to trick Kagome and Hojo into handing over the magic blade that their master needs. Kagome is suspicious to begin with, but her suspicions are confirmed when one of the three calls her by her name - which she hadn't mentioned to them.
I Shall Taunt You: Mouryoumaru tries to goad Inuyasha into getting so angry that he does something stupid by insulting Kagura's death. To everyone's shock (including Mouryoumaru's) the one who flies into an Unstoppable Rage is actually Sesshoumaru instead, who becomes so upset that he breaks Tokijin and puts his own life in danger.
If I Can't Have You: Naraku with Kikyou. He tricks Kikyou and Inuyasha into betraying each other, in hopes that he might be able to whisk the girl away after she's killed her former lover, but to much of his dismay she decides to choose death. Then when she's resurrected, he tries to kill her over and over again until he finally succeeds. He even wanted her to die in his arms, hoping that Inuyasha would be too late.
Impaled with Extreme Prejudice: Happens several times in the manga, bad guys impaling good guys, good guys impaling bad guys. Brothers impaling each other. One of the most dramatic occurances, however, takes place in the latter stages of the manga when Magatsuhi impales Sesshoumaru through the heart, bringing the entire cast to a shocked, disbelieving stand-still.
Implied Love Interest: Sesshoumaru and Kagura, whose feeling are never specifically confirmed but whose significance to one another is clear in the later parts of the storyline (and helpfully spotlighted by Rin).
In a Single Bound: Justified with Inuyasha and other youkais, not so much for humans.
In the Past, Everyone Will Be Famous: Subverted. When Inuyasha and Kagome meet a young samurai named Nobunaga, she immediately asks for his autograph excited to be meeting the famous Oda Nobunaga. It turns out he's Amari Nobunaga and is offended to be mistaken for that "idiot".
Incendiary Exponent: The first time Inuyasha turns into a human, he ends up having to fight a spider demon. So he pulls up a bunch of wooden grave markers amidst cries of blasphemy, sets them on fire, and then uses them as flaming javelins.
Infinity+1 Sword: By the end of the series, Tessaiga can generate huge energy blasts, reflect incoming energy attacks, launch a spray of adamantine spikes, cut through energy barriers, siphon demonic energy, and CREATE DIMENSIONAL PORTALS TO THE UNDERWORLD.
Involuntary Shapeshifting: Inuyasha turns human during the night of the new moon. He also transforms into full youkai when in danger (and not having Tessaiga near to seal his blood) and when a very corrupt Shikon shard is nearby (and not having Kagome near to purify him).
Journey to the West: a Shout-Out only found in the anime version is the appearance of a Boar Demon named Chokyukai, who claims to be a descendent of Chohakkai, aka "Disciple Pigsy". He also has a monkey and a scrawny kappa as his slaves, and claims that they are descendents of Shagoyjo (aka "Disciple Sandy") and Son Goku (aka "Monkey", aka "Sun Wukong"). Kagome has to explain to Inuyasha and co. that Chokyukai is talking about the famous tale of a Monk who travelled to India alongside a pig demon, a water demon, and a rebellious monkey god to retrieve sacred sutras.
The main characters mirror the Journey's main characters to some extent. Inuyasha just like Goku is bad tempered, is set free from a long curse at the beginning, has an elongable weapon, has animal traits and is subdued by a talisman which is under control of the person he's protecting. Kagome, like Tripitaka, is on a quest for a sacred item, is the reincarnation of a noble soul of the past, is the preferred target of demons and is helpless compared to most other characters. Miroku and Sango have some traits in common with Pigsy and Sandy respectively.
Just a Kid: Lord Kagewaki: "The most skilled [slayers]? But I see here before me a young girl, and you even brought a small child".
Just Following Orders: Byakuya's excuse to Sesshoumaru when he interferes with Sesshoumaru's pursuit of Mouryoumaru is, "don't hate me, I'm just doing my job".
Ki Attacks: Most all the attacks Inuyasha does are ki attacks focused through his sword; he rarely uses it to actually cut anyone, aside from monster-like demons. This is eventually lampshaded by Sesshoumaru, who cryptically advises his brother that he's put so many weird powers into the blade that he's forgotten what the point of a sword is (the point of the sword is to cut).
Killer Rabbit: Kirara. She's usually a very small and cute kitty with two tails but she can transform into a large saber-toothed cat with flames around her feet and tails, and in this form she's able to fly and carry up to three people on her back.
Kitsune: Shippo. One episode featured an Inn full of them.
Knife Outline: When Inuyasha was trying to steal the Jewel from Kikyo, instead of killing him she decided to pin him like this to a tree.
Kryptonite Is Everywhere: Even though the Wind Tunnel is the most powerful (and destructive) weapon, Miroku rarely gets to use it since it's vulnerable to poison, and more often than not the foe they're fighting is poisonous. Naraku has the Saimyoshou (poisonous hell bees) exactly for this reason.
Ladykiller in Love: Miroku falls hard for Sango. He still flirts with any beautiful lady, though.
Long Runner: The first anime was 167 episodes plus four movies, five in Japan. The Final Act added 26 episodes, for a grand TV total of 193. The manga started in 1996, and finally concluded in June 2008 with its 558th chapter. Overall the series ran for twelve years.
Love Dodecahedron: There are so many love triangles that include the two main protagonists that it inevitably results in this: Inuyasha/Kagome/Kikyo, Inuyasha/Kikyo/Naraku, Inuyasha/Kagome/Koga, Kagome/Koga/Ayame, Kagome/Inuyasha/Hojo, and then we have Inuyasha/Jakotsu.
Loyal Phlebotinum: Several weapons. Tessaiga initially appears to be this, then it seems to be averted when it's revealed Sesshoumaru can use it as well, it's only the youkai-repelling barrier that stops him. Finally, it's confirmed during a Die or Fly test of worth when Sesshoumaru deliberately steals Tessaiga's power to test its bond with Inuyasha only to find the power immediately flees back to Inuyasha at the first chance it gets.
Toukijin is so powerful and evil not even Toutousai can approach it. Sesshoumaru overcomes the blade's evil will easily and the sword obeys him loyally until the day it's destroyed.
Tenseiga accepts only Sesshoumaru as its true master even though Sesshoumaru doesn't want it at all. Even when he deliberately shatters the blade and discards it, the sword ends up reforging itself and landing back on the ground near Sesshoumaru. The only reason Tenseiga is not a Clingy MacGuffin is because it can be physically separated from Sesshoumaru. It just won't stay separated.
Luminescent Blush: Particularly Sango, but also Kagome and Inuyasha when things get a little too "romantic" between them.
Lunacy: Inuyasha loses his powers whenever is the new moon.
Magic Skirt: Kohaku has more panty shots than Kagome...
Man Behind the Man: Nearly every antagonist the Inu-tachi face is either working for or is a direct detachment of Naraku himself.
Near the end of the manga, it's implied that the Shikon no Tama, or rather, the aggregate demon inside it manipulated Naraku in a bid to free itself while perpetuating the Vicious Cycle. The last chapter implies that the Shikon no Tama was the REAL Big Bad that Kagome was sent back in time to defeat.
Master of the Mixed Message: Miroku so very much. His proposal is infamous for this: first telling Sango she's a special woman to him but later saying he can't love her and she's only a friend to fight alongside with, and then culminating with asking her if she would live with him and bear his child after Naraku is defeated.
Meaningful Name: The series is rife with them, starting with Inuyasha himself whose name means Dog-Yaksa. A yaksa is a spirit who in Buddhism serves a benevolent god that protects the righteous. Because Tessaiga is meant to be used for the protection of humans, Inuyasha's name suits him very well.
Another very noticeable example is the entire Band of Seven, whose names all end with "-kotsu" (meaning "bone"), indicating their undead natures. The prefixes of their names are individually meaningful as well; for instance, the "ja-" in Jakotsu's name means "snake," a reference to his serpent-like Whip Sword (accordingly named "Jakotsu-to," "snake bone sword").
Men Don't Cry: Inuyasha says this to a crying Shippo when they think Kagome, Miroku and Sango have died. When it turns out they haven't, Inuyasha tries to hide his tears which Shippo is fast to point out. Sesshoumaru also never cries, to the extent where Jaken will cry for him where necessary.
Demons do this all the time, fusing together to make more powerful demons. The Shikon Jewel was created when a particularly large number of demons fused to fight a priestess. After a long battle both souls fused and crystallized into the series' MacGuffin.
Naraku was created when the deranged and perverse thief (and Kikyou's Stalker with a Crush) Onigumo merged with thousands of demons. And at one point in order to obtain a stronger body, he perfoms a Kodoku spell: thousands of fierce demons fight inside a cave in a mountain, and the winner absorb and merge with the losers. Eventually Naraku ends up absorbing the surviving demon in himself.
Moment Killer: Kagome and Inuyasha get interrupted several times. One noteworthy example happens towards the end of the story when they’re alone in her house and are about to kiss when Souta comes crashing through the door.
Miroku and Sango on the other hand don’t need any help, they’ll ruin the moment themselves.
Morality Pet: Rin, for Sesshoumaru. Kohaku becomes something of a Morality Pet for Kagura for a short time until she dies saving his life, resulting in him defaulting to Sesshoumaru. One imagines that if everyone else got killed off, Fluffy'd probably end up with Shippo as well.
He himself admits once he has the complete jewel, he's not sure what to do with it, largely because all the things he wanted it for, he either already has now or doesn't need or want them anymore. He decides to just use the jewel's power to kill Inuyasha, and since he's spent so long fighting Inuyasha, he admits outright he's not sure what he's gonna do after that. It says something of how long the series runs that the Big Bad loses track of exactly why he's the Big Bad.
Kagome confronting Naraku near the end and making the unusually astute guess that The Shikon no Tama did not grant Naraku's wish is really one of the best moments of the series. Naraku states more explicitly at the moment of his death, that his wish was for Kikyou's love, and the possibility of being with her in the afterlife, which the Shikon no Tama could not give him. Failing this, he instead planned to replace Magatsuhi and Midoriko with himself and Kagome, by wishing to become part of the Shikon no Tama and by using the stolen Meidou to trap Kagome with the Shikon no Tama. (This of course was really the wish of the Shikon no Tama itself.) The (uncertain) implication is that Kagome could not be trapped in the Shikon no Tama unless she made a wish on it, and any wish would do except for the wish for the Shikon no Tama to be destroyed.
The Movie: Four times. They're generally non-serial, but occasionally nods to them are thrown into the anime, like Sesshomaru's Soryuha technique, which was made up for a movie. The fandom periodically circulates rumours of a fifth but that generally refers to either the ending of an old computer game or a more recent OVA that was released as part of the Rumic World Specials and can be found, with minor editing, as episode 15 of the the Final Act.
Muggle-and-Magical Love Triangle: Kagome has the most desired boy in school fall in love with her, but even when she goes on dates with him she finds herself thinking about Inu Yasha, half-dog demon from the mythic past.
Multi-Melee Master: All demon slayers are this, carrying a main weapon and a short sword, and if Sango is any indication, a chain and a hidden blade in their sleeve, too. Sango even fights with the Hiraikotsu and the sword at the same time.
He sometimes snarls when angered or sensing danger.
He bounces after a stick that Kagome purposefully throws with an excited face, and seems fond of pestering the Higurashis' cat.
In one of the OVAs and at another point in the manga, he shakes himself to get dry.
He usually tracks someone (often Kagome) by getting down on all fours and sniffing the ground.
He can also been seen kicking up dirt with his legs at an object when he's comically angered, such as when he and Kagome had a fight because of Koga. After Kagome's returned to her world in fury, Inuyasha is seen doing this to the well.
Chapter 392 ("Peaceful Table") has Inuyasha acting like a dog throughout the entirety of it, from scratching his head with his leg to run randomly in circles from boredom to cowering in an apologetic stance by Kagome's feet when she's mad at him.
Mystical White Hair: With a very few brown-haired exceptions, all of the normal humans in the series have black hair (or had it previously and went grey with age). The white hair of characters like Inuyasha and Sesshoumaru marks them as obviously supernatural.
Never Trust a Hair Tonic: Two demon brothers kidnap Kagome. She thinks they simply want to eat her, but it turns out one of them is severely balding and embarrassed about it, and he has heard you can get a hair growth potion by boiling down a human maiden. At hearing this, Kagome angrily insists they eat her instead.
Nice Job Breaking It, Hero: Literally for Kagome. She managed to kill the youkai that had stolen the Shikon no Tama but in the process also broke the jewel, putting into motion the plot of the story.
Noble Demon: Inu-no-Taisho was probably one. Sesshoumaru's mother might also be one, but her single appearance leaves it difficult to tell: although she participates in Inu-no-Taisho's plan to teach Sesshoumaru compassion, interpretations vary as to whether or not she demonstrates a Lack of Empathy. Character Development eventually lands Sesshoumaru in this category; other examples include Totosai, Housenki, and the fathers of Jinenji and Shiori.
As a rule, if you have a half-demon child, you are probably a Noble Demon.
Averted with Kikyou, who spent much of the manga as an evil mockery of her former gentle self while continuing to retain her healing abilities and her desire to heal. Eventually, her kind nature was saved and restored.
Not Brainwashed: After Kohaku regains his memories, he decides to act like he's still under Naraku's control to be near him and find a way to kill him.
Not Now, We're Too Busy Crying Over You: The end of the "Fateful Night in Togenkyo" story ends with Kagome, Miroku, and Shippo standing at the edge of a cliff and mourning for Inuyasha, who apparently fell to his death. When Inuyasha, coming up behind them, takes exception to Kagome calling him an idiot for dying, it takes the rest of the cast an extra line or two of dialogue before they catch on.
This happens a few times in the show. The first time is when Shippo first appears. Inuyasha is crying over Kagome who thanks to the foxfire protecting her, looks like a dead spirit (and Myoga the flea is so certain of this that he manages to convince Inuyasha).
Not Quite Dead: Kikyo quite a few times, she seems to be prone to fall from cliffs.
Not What It Looks Like: When Inuyasha refuses to let Kagome check on his injuries after their battle with Yura of the Hair, she tries to tear off his shirt in order to check for any serious damage. When Kaede and some of the children from the village bump into the two, they think they're doing....something else.
Now or Never Kiss: The reason why Sango kissed Miroku. Unfortunately for him, he was unconscious.
Nun Too Holy: Miroku is a Buddhist monk... who chases after women, has tried to peep on women bathing at least once, is willing to use violence to make others agree with him (he's beaten up the Tanuki Hatchi at least once, and then threatened to use the Wind Tunnel on him a different time) and is quite willing to fake exorcisms in order to get food, money, lodgings or any combination of the aforemention. Of course, this kind of plays on real-world stereotypes of actual monkish behavior from that time period.
Oh Crap: Naraku has several, like when Kagome blew up his body realizing she's Kikyo's reincarnation or when Kohaku tried to purify him with the light in his shard. In those instances he's always quick to run. His servants likewise get more than a few, especially Byakuya who thought he could handle Sesshoumaru with an army of a few thousand youkai to back him up.He was wrong.
One-Man Army: Despite the back-up his friends give him, Inuyasha is more than capable of this. His sword can slay a hundred youkai with a single swing... and that's its weakest ability. Then there's Miroku, who can take out many youkai with his Wind Tunnel (when he's allowed to use it). And Sesshoumaru's sword can slay thousands of youkai with a single swing.
The One That Got Away: Debatably Sesshomaru and Kagura, sounds like a classic case of losing the one you love before getting a chance to tell them how you feel.
Only I Can Kill Him: Everyone wants to kill Naraku, but Kikyo puts special emphasis on how she is the only one who can really do it. She doesn't, although her efforts prove integral to his eventual defeat.
The Only One Allowed to Defeat You: Sesshoumaru declares his claim on Inuyasha's life after Inuyasha receives Tessaiga, the sword that Sesshoumaru wants for himself. As his Character Development progresses, it's not long before his "nobody kills my brother but me" attitude starts coming across as a face-saving excuse to get involved in Inuyasha's battles without admitting that he doesn't actually want him dead any more.
There are in fact Only Four Faces - Young Woman, Young Man, Old Woman, and Old Man. The difference between the first two and last is also debatable.
Open Minded Parent: Nobody in her family minds that Kagome is gone for days or weeks at a time adventuring in a past era full of Youkai and missing a lot of school to do it, or that she's falling for a guy who's only half human; on the contrary, they cheerfully make up excuses for her to explain her absences.
Overtook the Manga: The first anime ended without any resolution when it overtook the manga. After the manga ended, a second anime Inuyasha: The Final Act was made and continued the story from where the first one left off.
Papa Wolf: Sesshomaru, who dives into hell in order to save his Morality Pet Rin and kicks the King of Hell's ass in order to save her and was very clearly in pain about her death.
Please Kill Me If It Satisfies You: Sango offered her life to Sesshoumaru after she tried to kill Rin to save Miroku. Sesshoumaru was initially angry with her and threw hiraikotsu at her (but missed and almost got Byakuya) but seems to forgive her after she gives Rin her gas mask as an apology and saves her from Naraku's shouki.
Please Put Some Clothes On: In the Tokajin arc, Inuyasha comes to rescue Kagome just to find her naked. After a few awkward seconds, he throws her his haori.
Pointy Ears: Usually to help identify who the human-looking demons are. Not all of them have it but still...
Power at a Price: Sesshomaru's quest for power results in the loss of his arm and, later, the death of Rin (again). He achieves his true potential only thanks to this and the death of Kagura; the latter moves him to feel compassion for others and the former forces him to understand the irreplaceable value of life and the role that fear and sorrow must play in a warrior's life.
Power Dyes Your Hair: Inuyasha's hair turns black when he turns human. Of course, the disappearance of his doggy ears is a much bigger marker.
Power Incontinence: The Wind Tunnel it's like a miniature black hole in the palm of the bearer that sucks everything in front of it unless it's sealed by special prayer beads. Eventually, it will grow big enough to break the seal and consume the bearer and everything around him.
Razor Wind: Kagura's 'Dance of Blades' is, of course, with blades made of air.
Really 700 Years Old: Any given youkai is potentially much older than they appear, and this can possibly extend to their half-breed offspring as well. Some specific cases:
Sesshoumaru confirms that Bokusenou is a two-thousand year old youkai magnolia tree.
Kirara, being a nekomata, falls under this as well; the anime even implies that she was Midoriko's companion.
Inuyasha himself is a cipher - the third movie establishes him as about 200 years old, not counting his fifty-year-stasis, but the movies are not considered canon to the series - but even if he was just a teenager when Kikyo put him on ice, Sesshomaru's appearance has not changed even slightly during the fifty years that Inuyasha was sealed. (And the same movie that gives Inuyasha's age as 200 shows Sesshoumaru looking only very slightly younger when Inuyasha was born, two hundred fifty years before the action of the series.) By extension, we may assume that Inu no Taisho and Sesshoumaru's mother age at a similar rate.
Red Eyes, Take Warning: When the eyes of Sesshoumaru and Inuyasha turn red it means they're going to transform into a giant dog and full demon respectively. Either way you should be running... fast.
Red Oni, Blue Oni: Inuyasha and Sesshomaru have this relationship going big time. Inuyasha and Miroku as well. Also, Jaken and Sesshoumaru as well.
Reforged Blade: After Tessaiga broke, Totosai reforged it with Inuyasha's own fang, which made the sword heavier. According to Totosai it means that Inuyasha now has to rely in his own strength instead of his father's.
Tenseiga is also reforged in order to activate Meidou Zangetsuha, triggered by Sesshoumaru's emotionally bruised heart because of Kagura rather than the blade breaking. Later on in the manga, Tenseiga does break in battle but reforges itself.
Revenge: The reason why most of the characters hunt for Naraku.
Revive Kills Zombie: More like "Killing 'Zombies' Revives". Tenseiga has the ability to cut the undead and the spirits from the underworld. By slaying the spirits that come to collect the soul of a dead person it revives said person.
Roof Hopping: There goes Inuyasha now, look at him go; boing boing boing.
Heck, Inu Yasha roof hops without roofs, somehow managing to double jump his way across the country side, way above the height of most roofs. To quote Kagome's friends, "Kagome's boyfriend runs like he's flying."
Rope Bridge: Jaken and Rin are confronted by a villain in the middle of a rope bridge. In a subversion, the bridge breaks because Jaken's attempt to defend himself and Rin relies on fire which burns the ropes and breaks the bridge causing all three of them to plunge into the gorge below.
Subverted more than once in the OVAs. In the 2nd, the command forces Inuyasha out of the path of Kaguya's attack. In the 3rd, just when it seems no force in the world can get Sou'unga to release him, he gets Sat with so much force that the beads explode!
"Would you like to bear my children?"
Miyoga always makes his appearance known by sucking blood off Inuyasha's nose and getting squashed for it.
Sadistic Choice: Kill an innocent little girl or the person you love the most will die. So, what are you going to choose Sango?
Scarily Competent Tracker: Inuyasha and Sesshoumaru with their heightened sense of smell. Jaken may also be this as, no matter how often Sesshoumaru leaves Jaken behind, Jaken always finds him again. How, is anyone's guess.
No matter his form, Naraku has a giant spider-shaped scar permanently on his back. In one episode he cuts off the flesh of his back to remove the scar only for the scar to immediately grow back in place.
Schizo Tech: Ginkotsu from the Band of Seven, a cyborg/tank in Feudal Japan.
Screw Destiny: One big theme in the series. Specially in the last battle which is against the Shikon no Tama itself.
Screw You, Elves!: Inuyasha delivers a rather impressive one to Sesshomaru; after the latter spends two or three episodes going off on how humans and half-demons are worthless, Inu not only slices Sesshomaru's arm off, but he also mocks Sesshomaru on how a mere half-demon got to inherit the Tessaiga.
Sealed Evil in a Can: The series final antagonist, Magatsuhi, the ancient composite demon inside the Shikon no Tama.
Sealed Evil in a Duel: Turns out the Shikon no Tama is really a container for an eternal struggle between a powerful Miko and a composite demon.
Second Love: Inuyasha's first love was Kikyou, but he ends up with Kagome. In the anime, Koga initially chases after Kagome but ends up with Ayame.
Secret Test of Character: At least half the time when Inu Yasha gains a new ability, and even more often whenever Kikyou gets within eyeshot of Kagome. And let's not forget Sango and Miroku when the former was getting Hiraikotsu repaired. Sesshoumaru's entire journey through the manga turns out to have been this, a test he finally passes when he obtains Bakusaiga.
Selfless Wish: Subverted in the backstory, where Naraku expects Kikyo to use the Jewel of Four Souls to save her life (she takes it with her into the afterlife instead). This sets up the ending, where Kagome and Inuyasha are trapped in the Jewel. Like Kikyo before her, Kagome doesn't make the selfish wish, but wished for the Jewel to cease to exist. She and Inuyasha get home safely anyway.
Shameful Strip: Kagome is knocked unconscious by the villain-of-the-week and wakes up naked in a big cooking pot. From the time Inu-Yasha rescues her until she retrieves her clothes, she wears his fire-rat-hair kimono.
Shapeshifter Default Form: Even though we know Naraku can take any form since that's the way he tricked Inuyasha, Kikyo and Miroku's grandfather, once he took Kagewaki Hitomi's identity he stayed with that appearance for the rest of the series.
She Will Come for Me: Kagome while inside the Shikon no Tama: "Inuyasha will come... I believe in him."
Shipper on Deck: Kagome, who tries to get Miroku and Sango together at times. Miroku, Sango and Shippo to InuYasha and Kagome. In Chapter 343 (animated in Episode 167), Rin is quite up-beat and happy upon realising that Kagura is in love with Sesshoumaru, to the extent where that realisation cures her fear of Kagura (earned as a result of Kagura having once kidnapped her on Naraku's orders).
Ship Sinking: Both the anime and manga end with Kagome and Inuyasha as (finally) a clear Official Couple. Hasn't stopped the fans one bit.
Shock Collar: Inu Yasha has a collar of enchanted prayer beads (or rosary) designed to make him hit the ground whenever Kagome says "Osuwari" or "Sit" / "Sit, boy". Kagome is an easily pissed off Tsundere Type B. Bad day for Inu Yasha.
Sins of Our Fathers: Miroku inherited the Wind Tunnel because his grandfather wanted to destroy Naraku.
Situational Sword: Tenseiga has the power to protect Sesshoumaru from death - but it only kicks in if Sesshoumaru sustains an injury that might potentially kill him without that protection. It's also incapable of killing the living, but turns out to be capable of killing spirits.
Spell My Name with an S: Due to confusion regarding the small "tsu" character (which emphasizes the consonant that follows it), the official manga translation printed the name of Inuyasha's sword as "Tetsusaiga" instead of "Tessaiga." The error was perpetuated in the official subtitles and English dub (albeit pronounced as "Tetsaiga"), and the fandom continues to argue over which spelling is more correct. (For comparison, Sesshoumaru's name also contains the small "tsu," but is never romanized as "Setsushoumaru.")
Not just the opening, but the first ending as well. The first ending focused on the main three female characters, Kagome, Kikyo and Sango. The problem is that Sango doesn't enter the story until episode 24, after the show has already moved to the second ending.
Spotlight-Stealing Squad: The Band of Seven are accused of this, seeing how their quirkiness and competence is far more memorable, so much, that you forget Naraku is the real Big Bad
Stable Time Loop: Implicitly the case with the Cursed Noh Mask. Kagome meets it in the present day, and brings its shard back to the past to complete the Shikon Jewel... meaning that the original shard is still in the past, where it will become the Noh Mask, which Kagome will bring to the past, etc.
While there was a lot of filler, limiting it to 20 chapters would pretty much require cutting out a ton of character development, and some of the cooler battles/arcs. Though considering how they both basically ended up disappearing by the end of the manga, and didn't really have much of a serious impact on the plot after their initial appearances, Takahashi could have probably ignored Houjo and killed off Koga after their first stories and not really changed the story notably. Hell, killing off Koga would have made a lot more sense than sparing him and it would have removed what is arguably Kagome's biggest scrappy moment in the series (which even she realizes was her fault).
Stealth Hi/Bye: Happens sometimes. One example is when Byakuya is messing with Inuyasha's group and they don't even know he's in the area. He decides to leave while he's ahead and suddenly discovers Sesshoumaru looming out of nowhere behind him.
Stepford Smiler: Miroku tends to hide his troubles and worries with a smile and a grope.
The Stoic: Inuyasha at times because he's a brood machine. Although Sesshoumaru's stoicism is somewhat exaggerated by the fanbase, he's still one of the most stoic of any manga or anime characters and is certainly the most stoic of this manga's cast. He is not unemotional, however, and there are plenty of occasions where he proves that he's actually Not So Stoic after all.
To elaborate: Miroku has what amounts to his own personal black hole in his hand, which he can use to suck any foe into oblivion. Early on in the series, Naraku begins using some poison bees that would kill Miroku if he sucked them in. This leads to nearly every episode having a scene where Miroku tries to use his world-breaking power, only for the bees to show up out of nowhere, forcing him to back off.
Strike Me Down with All of Your Hatred: Naraku urges Sango to kill him while he's holding Rin in his arms. Of course this being Naraku, he's not really going to die since he's only an illusion, but Rin is real and if Sango strikes the girl will die, filling the Shikon no Tama with darkness.
Suck Out the Poison: Myoga, being a flea youkai, did this twice. Once when Inuyasha was poisoned during his human night, and once barely saving Kagome, Sango and Miroku, when they almost died from Mukotsu's poison.
Summon to Hand: Tessaiga has done this for Inuyasha a few times, although is more Summon to Scabbard.
Sword Beam: Inuyasha's Wind Scar/Kaze no Kizu. Tessaiga's and especially Tokijin's "sword pressure". Also, Sesshoumaru's anime-only Souryuha.
Take Off Your Clothes: When he sees Kagome dressed as a miko, Inuyasha soon asks her to take off the outfit. To which Kagome respond with a rock to the head and calling him a pervert. But Inuyasha doesn't want to see her naked (yet); it's just that with the priestess garb, she looks too much like Kikyo and that makes him uncomfortable.
Taken for Granite: Miroku, Sango and Kirara were turned into glass in a filler episode.
Taking You with Me: Ginkotsu tries this to save Renkotsu from Kouga, but fails to kill the wolf youkai. Miroku also decides to take Naraku with him when the Wind Tunnel is about to consume him. Unfortunately, the Naraku he's trying to kill is only an illusion.
Talking Is a Free Action: In the manga. "You think you can defeat me with that lightning-fast attack you're doing right now? Fool! I am going to dodge it as soon as I finish explaining what's going on in this battle!"
Tear Off Your Face: In one arc, Naraku expels his heart, which takes the form of a naked faceless man, who proceeds to slay a whole bunch of bandits and rip off their faces, looking for a suitable one for him. Without them he's shown to be The Blank.
Timey-Wimey Ball: Not a big problem, since the "fighting bad guys" matter more than the time traveling, but for example, Kagome finds a jewel shard in the present. So that means it's also back in the Sengoku period, meaning the Shikon no Tama eventually comes up to complete plus one extra shard stuck in a tree somewhere. Souls also seem to transcend time in that Kikyo can't be reborn with her soul because it's already been reincarnated in someone else — someone else from the far future who hasn't been born yet, even if she happens to have will have travelled back in time.
Took a Level in Badass: Kagome does manage to catch up and become a true Action Girl. She also develops from barely being able to fire a bow to making shots that are borderline impossible for trained archers in the real world.
Took a Level in Kindness: Inuyasha, Sesshoumaru, Kouga, and Kagura all experience this at varying speeds and to varying degrees.
Toplessness from the Back: All main female characters. Subverted by Sango and Kagura since it's done to show the large scars they have on their backs.
Traumatic Superpower Awakening: After first being sent to the past, Kagome first becomes aware of the Shikon jewel inside her when attacked by a demon. Though the jewel is expelled, this incident results in her learning of her other latent powers.
Triang Relations: The Inuyasha/Kagome/Kikyo Triangle is closest to a Type 7 situation, where "Alice" is Inuyasha, and "Bob" and "Charlie" are Kagome and Kikyou who are rivals rather than having no interaction. Inuyasha was effectively engaged to Kikyou when she died and his relationship with Kagome was already well under way when Kikyou came back from the dead (shortly after Kouga's entry into the storyline, Kagome and Inuyasha are a confirmed couple), making him honour-bound to both women and completely unable to choose between them. At one point he even admits to Miroku that he was hoping he could solve the problem by having them both (which would have been relatively common for a man in Japan's past, but modern-girl Kagome was definitely not thrilled by that suggestion).
It doesn't help that Kagome is Kikyo reincarnated.
Trickster Twins: Miroku and Sango's twins seem to be growing up to be this. With that father it really isn't a surprise.
Treacherous Spirit Chase: Inuyasha nearly gets killed by a youkai disguised as his mother who has been dead since he was very young. If Kagome hadn't seen through the illusion and managed to convince Inuyasha that things weren't what they seemed to be, he would have died.
Treasure Chest Cavity: Inuyasha's father's grave is inside his pupil, and Kagome kept the Shikin jewel inside her soul.
Tsundere: Kagome, though being a Tybe B aka more deredere she later mellows a bit. Inuyasha could count a bit as a male example, and Sango also has some flashes of Tsundere-ness despite being kind of a Yamato Nadeshiko.
Unwanted Revival: Kikyo. She had chosen to die to follow Inuyasha and to take the Shikon Jewel with her to the afterlife, but things didn't quite go her way. She was not only reincarnated (along with the Shikon Jewel) but she was revived into a clay body.
Victim of the Week: As with other fantasy stories, the main purpose of the villagers are to be either held hostage or brutally killed ten ways to Tuesday in order for the heroes to know just how bad the Monster of the Week is.
Viewers Are Goldfish: The recaps can get pretty ridiculous. The Japanese version also reminds you who every single character outside of the Five-Man Band is, every episode, by showing their name over the entire lower half of the screen.
Even the Five-Man Band wasn't immune to this, with their names being verbally announced along with onscreen captions during the opening credits.
Welcome Back, Traitor: The group forgives Sango quite easily for betraying them (and almost getting everyone killed, herself included), after Naraku forces her to choose between doing what he says (steal Inuyasha's sword and give it to him) or letting a loved one (Kohaku) die. Even when she warns them she will do it again, they still forgive her.
During the final battle, Naraku makes Sango face exactly the same choice again: do as he says (kill him by killing Rin) or let a loved one die (Miroku this time). She fulfills her earlier warning by making the exact same decision. Although Sango gives her life to Sesshoumaru in compensation for trying to kill Rin, he was initially angry with her and threw hiraikotsu at her (but missed and almost got Byakuya) but seems to forgive her because she saved Rin twice after that.
What a Piece of Junk: Tessaiga/Tetsusaiga when not transformed. Bonus points for Inuyasha saying this trope word for word in the sixth and seventh episodes.
What Happened to the Mouse?: Even as the OVA's are considered questionably canon to the original story, the second movie deserves a mention for showing Kagura and Kanna being sucked towards the bottom of a lake after being out-gambitted by the villain. We never learn what happened with them, if they drowned or escaped or what.
What Kind of Lame Power Is Heart, Anyway?: It's eventually explained that the reason that Midoriko, the Miko sealed in the Shikon Jewel, was so powerful was because her heart bore each of the "four souls": Aramitama, Nigimitama, Kushimitaka, and Sakamitama. That is, Courage, Friendship, Wisdom and Love. An anime Villain of the Week reveals to Inuyasha and friends that other Shikon Jewels can be made if you can find four souls that strongly embody each of these four characteristics and seal them into a single gem with a Miko as the center. In fact, he attempts to defeat the group because Kagome (the Miko), Inuyasha (Courage), Shippo (Friendship), Miroku (Wisdom) and Sango (Love) are pefect candidates for this process.
A more canon example, this is the lesson Sesshoumaru's entire journey through the manga leads him to learn.
With Great Power Comes Great Insanity: When Inuyasha transforms into a full demon he gets incredible strength and resistance, but it's too much power for his half-human body to handle and he'll start to lose his sanity with each transformation until he'll end up being a mindless killing machine that will keep fighting until he destroys everyone around him or gets himself killed.
The Worf Effect: Sesshoumaru is the favored "test target" for Naraku's new abilities/henchmen.
Would Hit a Girl: Inuyasha impaled Yura through her chest with his hand, Kouga hit Kagura in the face and Miroku punched Sango (and other girls) to free her from a youkai in her stomach possesing her.
Would Hurt a Child: Naraku has no compunctions about doing any horrible thing to anyone, children included. Various other youkai such as Goshinki share his willingness to harm kids; even Kouga has no issue with letting his wolves kill Rin during his first appearance (although his personality is considerably softened thereafter). Kagura may be a notable exception, given that she fails to do anything more serious than kidnapping Rin, and becomes quite protective of Kohaku. Thanks to a multiple personality disorder, Suikotsu flipped between being a gentle doctor who wouldn't hurt a fly to a homicidal maniac that was willing to include children in his body count.
Wrecked Weapon: Goshinki broke Tessaiga, breaking with it the seal on Inuyasha's youkai blood.
To save Miroku, Sango sacrificed Hiraikotsu spreading in it a very corrosive poison that succeeded in destroying the youkai they were fighting, dissolving the huge boomerang as well.
On the other hand, Sesshoumaru didn't give a damn when Tokijin broke.
Honouring a promise to Inuyasha, Sesshoumaru sacrifices his claim to both swords by deliberately shattering Tenseiga's blade against Tessaiga to pass on Meidou Zangetsuha. The broken Tenseiga responds to this by guiding the pair out of the danger they're in and promptly reforges itself. Sesshoumaru can't get rid of this blade even when he tries.
Yamato Nadeshiko: Sango looks and acts the part... and that doesn't stop her from being an effective Action Girl, since her family's tradition is demon slaying. Also, Kikyou was quite the Yamato Nadeshiko before her death.
Yandere: Naraku/Onigumo, the original evil spirit of the Shikon no Tama, and, of course, Jakotsu.
Kaede continues to use it to an extent all through the dub, which is particularly jarring in episodes where Kikyo also appears, since she speaks perfectly normal English.
You Are Not Alone: After failing miserably at defeating Naraku and saving her brother plus having just betrayed her new companions, Sango tries to leave the group but the others don't let her telling her that being alone is not a solution and it's best if they all stay together.
Sango: "I was really scared... I was scared that I'd be alone"
You Are Worth Hell: Sango prefers to stay and die with a poisoned Miroku than save herself while being chased and cornered by youkai. And in the final battle when the Wind Tunnel is about to consume him, she asks him to take her with him.
You Must Be Cold: Inuyasha gives his fire-rat haori to Kagome several times throughout the series, most times because it's resistant to fire, poison and sharp things, but a few times because she's actually cold or to protect her modesty.
Youkai: Running around everywhere including Inuyasha.
Zigzag Paper Tassel: The goshinboku tree has a shimenawa around it in the present, but not in the past. Also, one chapter features some monkeys who trick Inuyasha into touching a small stone with a shimenawa around it, which sticks to his hand and becomes a huge boulder.
