History NightmareFuel / Inuyasha

* The world is very scary for a ''romance manga'' of all things. To put it bluntly, it's a death world out there with every other villain being some sort of utterly depraved man-eating demon that would put most villains from ''Anime/DemonSlayerKimetsuNoYaiba'', ''Inuyasha's'' BloodierAndGorier and DarkerAndEdgier counterpart to shame. Random [[MonsterOfTheWeek fuck-off villains]] routinely wipe out entire villages and massacre and torture hundreds and commit every nasty crime imaginable -- for a few examples, there's a demon who usurps a benevolent water deity to eat children, another who uses his granddaughter as a meat shield and kills his son for falling in love with a human, yet another who leads entire groups of humans to RapePillageAndBurn village after village (with his human minions getting amazed by his identity as a yokai, and that's not even getting to the arch-villains like Naraku, the Infant and the Band of Seven, each of them responsible for the deaths of thousands after thousands. You know it's very bad when the first thing we see on a panel upon introducing a villain is usually piles upon piles of dead bodies and/or blood. Being the chief of a village and your son goes out to take a piss? Maybe when he returns he's possessed by a vicious, man-eating demon. Going to a temple or motel for a rest thinking you'll be safe? Who knows if that's actually a man-eating demon craving for human flesh who pulled a KillAndReplace on its original owner. It really gives a feeling that no matter where Inuyasha, Kagome and co. goes, nowhere is safe, and they have to be on the hit-and-run all the time, because mass-murdering yokai are literally ''everywhere''.

* Naraku's [[spoiler: true body during his weakened phase, which consists in a loathsome blob of Youkai body parts and flesh]]. He often has them fighting against each other so that he can absorb the winner and he is not above GrandTheftMe if he's ever [[HoistByHisOwnPetard absorbed by one]] [[spoiler: As the Infant can testify]]. For this reason, he is full of LovecraftianSuperPower, full of CombatTentacles and other BodyHorror; which gets even worse once he becomes a full demon.

** [[spoiler: Both his giant black spider form, [[BodyHorror making his face appear inside his body]] and red skinned demon form, all of which make his final battle very frightening.]]
** Even his incarnations are this, Goshinki is a red-eyed, purple, people-eating demon that is strong enough to [[spoiler: break the Tetsusaiga in one bite]] and ridiculously fast, but the worst part of him is his mind-reading capabilities, which he can use to drive you to despair by exploiting your inner weaknesses. Others including Kageromaru and Juromaru, a parasite and his mindless brute brother, as well as The Infant capable of MindRape capable of causing Kagome into a HeroicBSOD. Even Muso, TheBlank who can steal your face, capable of absorbing demons and his eventual [[YouWillBeAssimilated fate]] is considered one.
* The Cursed Noh Mask, made from a sacred tree imbedded with a Sacred Jewel shard, that feeds on people to gain a body, a blackish one made of absorbed corpses. What makes it worse than most demons after the shards is that it was awoken in the present day by being near its presence. And it goes on a killing spree targeting firemen and policemen as well as driving a FIRE TRUCK into Kagome's house to get the Jewel. Oh and there's not any [[NoOntologicalInertia reverse of the damage it's done]] yup the people the mask has eaten are gone for good.

* The Curse of the Ink episode, involved an artist who drew hellish demons in order to get what he wanted, but ends up suffering a FamilyUnfriendlyDeath when [[spoiler: he is aged to death]]
** In the manga, [[spoiler: The living Ink, attracted by the artist's blood, sever his arm and then proceed to devour and melt him like a blob monster.]] Inuyasha even tries to save him, but is just left clutching his arm.

* The Snake demon of the Orochi clan who was desperate enough to bite a piece out of [[spoiler: Moryomaru's arm]]: as a result, said piece of flesh ''bursted'' from his orifices and then swallowed him up from the inside in a truly horrific manner.
* Not all scary things in ''Manga/{{InuYasha}}'' can be just demons, when [[spoiler: Kohaku]] goes from shy to emotionless killer, a change so sudden that it takes both Kagome and the audience by surprise. Even more disturbing is the SadisticChoice of Naraku in that if [[spoiler: Kohaku remembers killing off his own family]] he'd likely GoMadFromTheRevelation and be DrivenToSuicide to escape the guilt. Naraku you bastard
* The Maker of the Shikon Jewel {{Filler}} involves a radical JekyllAndHyde involving a bull demon [[spoiler: who is actually a half demon priest who turns into a demon at night]], which is scary enough except the DissonantSerenity and subtle build-up to this is very shocking to say the least.

* St. Hakushin, an undead priest with BlackEyesOfCrazy; his backstory explains that he allowed himself to be BuriedAlive only to hit the DespairEventHorizon as he realized that he didn't ''want'' to die and that all of the villagers were praying for his death. [[spoiler: The MoodWhiplash of Mt. Hakurei transforming from a peaceful mountain to a hellish peak of spikes]] does not help matters.

** [[spoiler: Tekkei's FamilyUnfriendlyDeath when Naraku bursts out of her forehead with CombatTentacles]].

* Just when [[spoiler: Naraku is finally defeated]], [[spoiler: The Sacred Jewel decides to seal off Kagome in a pitch black space and the demons that make up Magatsuhi, complete with VoiceOfTheLegion show to stop Inuyasha.]] It makes for a rather creepy climax, complete with an eerie soundtrack playing in the background.
* The [[JackassGenie true nature]] of the Shikon Jewel itself. While it said it could grant any wish, in reality it doesn’t grant it at all at best, or it will twist for its own ends at worst. Even Miroku suggested that possessing it will bring sorrow and doom, and it’s stated InUniverse that every attempt to use it for good reasons, always backfired horribly. Not only that, but it’s revealed in the climax that [[spoiler: it has a will on its own, and that it staged all the events to make sure it would continue its existence, by attempting to seal both Naraku and Kagome]]. [[spoiler: Good thing Kagome wished its cessation of existence, which turned out to be the “true wish” that the jewel can’t pervert it.]]

Creator/RumikoTakahashi in this series has really demonstrated that she can create some very creepy and unsettling entities, ranging from BigCreepyCrawlies to [[RedEyesTakeWarning red-eyed]] [[HumanoidAbomination humanoid]] ones.

* Tokajin, [[CoolSword no, not Sesshomaru's sword]]; rather a man turned demon sage who feeds off of a man eating tree, nourished by men he has trained to become spiritually aware enough so he can kill them. That is scary enough, but the man himself, is a plump [[UncannyValley vaguely human]] creature, quite unlike the {{Bishonen}} and [[NightmareFuel down right terrifying]] in the series.

* Onigokuki, a demon slave trader who lures children with his flute to be sold to other demons. It's full of AdultFear of child kidnapping and the implications of slavery.

* Just when [[spoiler: Naraku is finally defeated]], [[spoiler: The Sacred Jewel decides to seal off Kagome in a pitch black space and the demons that make up Magatsuhi, complete with VoiceOfTheLegion show to stop Inuyasha.]] It makes for a rather creepy climax, complete with an eerie soundtrack playing in the background.

* Princess Aibi's Fire Birds. For one thing, they're white pterodactyl like creatures that ignite at will and an alarming screech, not to mention her mother, Tekkei, who first appears as a realistic looking red eye, later revealing to be a threatening phoenix like creature.

* Hitomiko, a priestess killed by Naraku and brought BackFromTheDead to be his [[FangsAreEvil fanged]] puppet, which is scary enough, but then it's revealed that 15 years ago, he once suddenly to her as a little girl with the full intent to kill her just on the chance of being a threat. When that failed he reduced her friends to corpses and killed her master It's a rather jarring action coming from a [[ManipulativeBastard normally manipulative]] [[TheChessMaster chess master]] who only kills to further his ends.

* The Priestess Eater, an EldritchAbomination of a demon that lures in priestesses with a little girl in order to swallow them with the cave that is its body. [[BodyHorror its main core is a brain mass with a single eye and several tentacles]].

** In the manga, [[spoiler: The living Ink, attracted by the artist's blood, sever his arm and then proceed to devour and melt him like a blob monster.]]

* Sesshomaru's [[OneWingedAngel true form]]--a [[RedEyesTakeWarning red-eyed]] dog that is as big as a truck. While his regular form is graceful and {{Bishonen}}, his true form is rapid, beastly and constantly drooling acid. The first transformation into it prior the pink smoke is his face turning into a canine face complete with SlasherSmile.

* Miroku watched his own father get devoured by the Wind Tunnel in his hand, right in front of him, when he was a little boy. And he's living with the knowledge that unless he defeats Naraku, the same thing is going to happen to him.

* Naraku's [[spoiler: true body during his weakened phase, which consist in a loathsome blob of Youkai body parts and flesh]]. He often has them fighting against each other so that he absorb the winner and he is not above GrandTheftMe if he's ever [[HoistByHisOwnPetard absorbed by one]] [[spoiler: As the Infant can testify]].

* Kao, the Flower Demon. Doesn't sound intimidating right? Turns out he puts people in a LotusEaterMachine that makes their eyes have TearsOfBlood.

* Bone Demon and her father, the former disguises a beautiful woman, but in reality is a red eyed demon [[BodyHorror that can absorb the bones out of your body through her hand]] and her father is a red eyed demonic skeleton.

* The Village of Demon Women, sure the Salamander demon is very {{Narm}}y in her "water lipstick face" form until she returns to being a rotting salamander; but what she has the women do is very unnerving. She implants eggs to parasite off of them and have them skin men alive.

* When Sesshomaru smells blood and the scent of wolves on the air, and goes looking for the little girl who helped him - and finds her body lying on the woodland floor, face down and empty-eyed. Sure, Rin got better, but that doesn't change the fact that she was ''mauled to death by wolves.''

** To make this even better/worse, Saint Hakushin is a [[http://en.wikipedia.org/wiki/Sokushinbutsu sokushinbutsu]] - what happened to him was at one point an entirely real, historical practice (now actively banned in Japan, for obvious reasons).

* St. Hakushin, an undead priest with BlackEyesOfCrazy; whose backstory is his realization that he was being BuriedAlive. [[spoiler: The MoodWhiplash of Mt. Hakurei transforming from a peaceful mountain to a hellish peak of spikes]] does not help matters.
