''Videogame/ShinMegamiTenseiIV'' brings us a world full of bloodthirsty demons, [[HumansAreBastards terrible]] [[HumansAreTheRealMonsters humans]], and the various [[BowelBreakingBricks brick]]-inducing horrors that come as a result of them, spread across two worlds. Even as a well-trained Samurai, you'll probably be longing for the cushy, sheltered lifestyle of Mikado's Luxurors or the relatively-safe underground districts of Tokyo after you're done reading this page.
----
!! I'm detecting Nightmare Fuel ahead. Be careful.
* The Nightmare Fuel is present in this game, even before you start it up. Imagine, if you will, putting the cartridge into the 3DS and expecting a little jingle or a character saying the game's name, only to be greeted by an abrupt [[ScareChord DUNNNNNNNNNNN!]]
* Demon's Domains. Labyrinthine {{Pocket Dimension}}s that take over a particular area and feature pulsating tentacles and deadly demons throughout, often designed to lure, capture, and kill humans. In the first one you enter, you see [[spoiler:Navarre and his companions]] bound to the walls in the background of Alraune's chamber, with Alraune prepared to feast on their blood--sure, [[spoiler:Navarre is a [[FantasticRacism classist]] [[JerkAss asshole]]]], but he's scared shitless, like most anyone would be if they were captured in that fashion--in fact he's so terrified that [[spoiler:he locks himself up in his room for days afterwards, crying and screaming like a madman.]]
* When Issachar [[spoiler:gets possessed by a demon and his [[RedEyesTakeWarning eyes turn red]], which doubles as NightmareFace]].
** [[spoiler:The way his battle sprite ''twitches'' during the fight. Becomes even worse if you tell him you still consider yourself a Casualry, in which case he'll try (and fail) to [[FightingFromTheInside fight from the inside]].]]
** [[spoiler:Before he dies, you'll see his character portrait bleeding heavily]].
** [[spoiler: Much later in the game, one of The White takes his form... but ''permenantly crying''. It's a lot creepier than it sounds. And then the White starts actually showing some emotion as it speaks as it dies, moaning in Issachar's voice, lamenting he could not be saved...]]
* In the bad ending, [[spoiler:you are required to destroy the Yamato Gate to activate black holes that will consume the whole universe and destroy everything. The "battle" with the Yamato Gate, [[NoHoldsBarredBeatdown if you can even call it that]], is accompanied by very eerie music. While the background is the same as most bosses you fight throughout the game, the music coupled with the [[NothingIsScarier empty background]] makes it very unsettling.]]
* The music for [[spoiler: Merkabah and Lucifer]]'s second forms are likewise very unsettling.
* East Mikado itself. Even at the beginning of the game, its clear that there's something very ''[[UncannyValley off]]'' about the whole place, from the brutally racist caste system, to the fact that demons live literally right underground the capital city, and the fact that, if Isabeau's comments about France[[spoiler:'s status as a fictitious country]] are anything to go by, ''they believe themselves to be the only civilization in existence''.
** And then after [[spoiler:you capture the Black Samurai]], you find out that [[spoiler:they consider ''public executions'' ''national holidays'']].
*** [[spoiler:This is actually TruthInTelevision. It's a comparatively recent development for Executions to be treated as something to be hidden from the public at large. This can also be seen in PiratesOfTheCaribbean, as well as any WildWest movie with a hanging occurring. It was considered a day out, a time to put on the fancy clothes and gossip with your friends.]]
*** [[spoiler:The execution ceremony was used as a chance to order the Samurai to travel around Mikado and "execute" those who have been found reading Literature or otherwise following the Black Samurai. One Samurai states that Hugo told him to [[DeadlyEuphemism call them "executions" rather than the cold-blooded murders that they are]].]]
** Towards the end of the game, [[spoiler:the Archangels initiate a bloody purge in Mikado in preparation for Merkabah's arrival. Anyone, whether Luxuror or Casualry, who has read '''any form of book''' is butchered (Isabeau is among this list because she reads ''manga''. Even Jonathan would have been added to the massacre had he not joined the Archangels because of his research beforehand). It's implied this caused the near-complete extermination of the entire Luxuror caste]].
** During the Lawful Ending, [[spoiler:you commit what is tantamount to genocide on the entire population of Tokyo. Merkabah also forces you to commit HeroicSuicide with him, because the two of you have learned about the "Filth" of Tokyo.]].
* The Ashura-Kai building and the secret of how they make Red. [[spoiler:The demand's up and the women (which they openly call ''[[FridgeHorror bree]][[RapeIsASpecialKindOfEvil ders]]'') just can't cope, ''[[MoralEventHorizon so they want to start using the children]]''. The slaves there are imprisoned in tiny, bloodstained rooms with buckets of filth in inhuman conditions, brainwashed to love Tayama (a girl comments she once told Tayama she loved him and hoped to be his wife, ''and the asshole told her "Age is no barrier to love"''), used as seedbeds, and having their neurotransmitters ''harvested''. There are people strapped to chairs and treated like livestock, nearly mindless, as they have the ingredients for Red extracted. ''Friggin' Lilith'' herself is disgusted by this. As is, well, ''everyone''. Law, Chaos, Neutral. They ''all'' find Tayama disgusting.]]
** The poor sap you find in the [[spoiler:Reverse Hills Building, clearly retarded to a childish intelligence by continuous harvesting, still moaning very familiar catchphrases. There are children proud of using buckets as toilets, children abandoned or sold by their parents, children brainwashed with Tayama's cheap slogans, being told to say they are being educated. The underground city dwellers are bought, bribed or captured to enter Reverse Hills, only to become more raw materials for Tayama's Red Pills. ''[[FridgeHorror And the place is over fifty floors underground]]''.]]
* As horrible as Reverse Hills is when you first visit, a post-alignment lock visit will reveal it's only become ''worse''.
** ''"Mister, listen! We learned about "hope" today! [[TroublingUnchildlikeBehavior Tokyo has no "hope"]].''
** ''"I thought Mom and Dad were in a different building. But the Ashura-kai guy told me they left on a long trip a while back. They went to this place called "Heaven"."''
* Post-alignment lock, the residents of the Dogenzaka area despaired and eventually found hope... in the Red Pills. The few humans in the area are gone, leaving only the demons.
* When you defeat an opponent in a tournament, the audience expresses ''[[WhatTheHellPlayer complete dismay]]'' [[VideoGameCrueltyPunishment if you don't]] [[InvertedTrope kill them]]. Very much reminiscent to the Colosseum fights of Ancient Rome as you are encouraged to kill your opponent.
* The [[spoiler:Monochrome Forest]], mainly due to [[http://www.youtube.com/watch?v=6zmOjkUQQ6Y this music]], and what it represents to the game's story.
** To say nothing of its ''rulers''. [[spoiler:The White are OmnicidalNeutral [[TheHeartless embodiments of humanity's despair]] at the sheer [[CrapsackWorld suck]] of the Megami Tensei universe, and wish nothing more than to destroy it, since it's the only way out. And the thing is, they're just so ''reasonable'' about it, it's hard to not find yourself nodding along to their reasons for thinking the solar system needs to go. It's very easy to find yourself thinking like them, and that's the most terrifying aspect of all.]]
* ThePurge the angels enact is justified in their eyes, as the literature the Black Samurai has been distributing turns humans into demons. The problem? [[spoiler:''It's normal, human world literature''. The people of East Mikado have their beliefs in social castes so ingrained that when an outside force like the books makes them realize there ''are'' alternatives to the CrapsackWorld, they go insane with horror, rage and grief, which ''is'' what triggers the demon transformation.]]
* Most of [[spoiler: Blasted Tokyo]] is pretty awful, what with it being a literal wasteland of poison and despair. On your way to combat the source of one of the problems affecting the place you're stopped by a trio with a request to put down a demon in Shibuya. Go there and you find [[spoiler:it's a dark, literal ghost town, the human population long since killed off, but earthbound due to the intervention of Ixtab, a Mayan suicide deity. Kill her and some of them fade away, and most of the rest get angry with you for consigning them to the same fate.]]
** Also in Shibuya, [[spoiler:the game suddenly stops as you approach the stairs to the second basement so that [[BossWarningSiren Burroughs can warn you of a "strong demon" ahead]], which can come off as an unintentional JumpScare.]] The same thing happens in Ikebukuro too.
* [[spoiler: The process of making Neurishers and Demonoids can be one. Like normal demon fusion the surgery to make a Demonoid can result in ''fusion error'', which some poor soul ends up suffering from in Camp Ichigaya (he turns into a [[BlobMonster Mou-Ryo]]). The Neurishers have to deal with the fact that they'll die if the parts the demon making them into one uses are faulty, and there's no real way of checking before he uses them in the surgery.]]
* [[spoiler:Lucifer and Walter's fusion. Let's just say it doesn't seem to be ''quite'' as painless as normal. That's not even getting into [[http://img1.wikia.nocookie.net/__cb20130906211305/megamitensei/images/b/b9/Lucifer_smt_4.png Lucifer himself.]] While the [[FashionVictimVillain getup]] may be a little goofy, his overall appearance is horrifying: something decidedly [[HumanoidAbomination inhuman]] trying to be human and failing horrifically. Or worse, going by the themes of the game, something that is [[HumansAreTheRealMonsters humanity]] distilled to its purest essence... With Merkabah on the other end, it's really hard not to ask oneself exactly who and what we are to create such abominations.]]
* [[spoiler:Hell, ''both'' Merkabah and Lucifer are completely insane. Merkabah wants to kill Isabeau because she's read ''manga''. Lucifer just outright insults her as she dies.]]
** [[spoiler:''[[FamousLastWords "I will not... let your hands... be stained... At least, m-my last choice... will be my own..."]]'' [[BetterToDieThanBeKilled Isabeau slits her throat.]]]]
* The archangels in this game, no longer the human looking beings with wings, they properly assume their form as inhuman abominations.
** Even before they are formally introduced, there's this feeling of utter wrongness in the kingdom. The king has been removed from power, and no one bothers to think where he went. The castes are being dissolved, and all of a sudden even the most pampered Luxurors are worrying about physical work. Dissidents and followers of the Black Samurai are disappearing. A man mentions his son was caught at a Sabbath and added to the execution list, and as "expiation", he was given ''another child to raise''. Most demons are gone, and most disturbingly, many people talk about being contacted by "the new rulers" via dreams - dreams that helped ease the transition too smoothly for comfort. And then Sister Gabby ushers you into the Cocoon...
** Their debut is absolutely this. These warped, utterly inhuman, incomprehensibly powerful...THINGS descend upon the heroes, looming over them in a way that makes the samurai look absolutely tiny. They calmly introduce themselves and tell you that [[TyrantTakesTheHelm THEY run the show now,]] revealing the truth about Tokyo in the process: the hellhole is made up of people who didn't fit into their utopia, who they shall again attempt to exterminate should they try to leave their cage, and they are in the middle of another cleansing. Gabriel commands you to kill the Black Samurai, saying her death is the only thing they need concern themselves with, and the samurai can do nothing but leave, utterly cowed and looking absolutely impotent. The icing on the cake? [[spoiler: [[NiceJobBreakingItHero You're solely responsible for this:]] the masked people you saved from Kagome Tower earlier were Michael, Uriel and Raphael. You are ''personally'' responsible for unleashing these fascistic, godlike {{Eldritch Abomination}}s upon your home.]]
** [[spoiler: What arguably makes their scenes even worse,is their DissonantSerenity.It's hard to not find their cold declaration of genocide very unnerving.]]
* Ikebukuro is downright brutal. [[spoiler:Poison spills all over the place, creepy music, and an underground district with abandoned shops and an abandoned Hunter's Association, and the same creepy music playing there until Xi Wangmu is defeated. There's also an NPC here who's on her dying breath--you can either tell her you're a human, giving her some solace before she passes away, or lie to her about being a demon, making her feel like she's lived a life of regret. Said NPC is ''gone'' when you visit the same room again.]] Ironically, Ikebukuro is ''less'' nightmarish in [[spoiler:Infernal Tokyo; there's no poison lining the area outside of the station, and the underground district is operating at full capacity, although there is a Domain housing the four HorsemenOfTheApocalypse there.]]
* The GameOver scene, should you refuse to accept Charon's offers to revive you. "Let me be clear: Your turn will come up '''long after the wind erodes the boulders down to sand.'''" What he means is: The queue to cross into the afterlife is so long that you're forced to wait it out for millenia.
* There's something very intimidating about the equipment shops in Tokyo, which are black market branches run by greedy, JerkAss yakuza-esque thugs. It's also a huge contrast to the exceptionally polite shopkeepers back in the Eastern Kingdom of Mikado.
--> '''Dealer:''' "Make sure you bring more Macca next time!"
* ''Mysterious Story of Tennozu''. You get asked to investigate a cult in Tennozu Shelter where investigators keep disappearing. People there are really well-fed without resorting to demon meat, and insist they have beef, a patent lie in the sealed Tokyo (even growing produce is tremendously hard due to the lack of an actual ''sun''). Later, you must confront the cult's leader as they finish some sort of SummoningRitual. While disarming the leader, the entity manifests. But it needs an offering to gain physical form... [[spoiler: It's Baal, who proceeds to ''chow down'' on his worshipers. Oh, and that meat the shelter survivors had? Baal's festivals had a cow presented amidst chants and prayers, then sacrificed and served as food. But another worshiper clarifies that since they could get no cows, they presented a normal man dressed in the sacrificial decorations - and then the festival continued on [[HumanSacrifice with only that slight variation]].]]
** Goes FromBadToWorse during the second part of the questline, ''Rebirth of the Great Overlord'', where [[spoiler: Baal's true form is revealed as TheDreaded demon, Beelzebub. Cue player voiding his or her bowels, [[ThatOneBoss followed swiftly by a spam of Megidolaons and the Game Over screen.]] It helps very little to remember Beelzebub is, in fact, the Demon Lord supporting the sin of Gluttony.]]
* For that matter, the Tennozu shelter music is pretty creepy. It also plays in Minami Sunamachi, a part of Tokyo that's deserted save for refugee demons, chock full of poison gas, and [[ParanoiaFuel has one of the 1/256-rate]] [[BonusBoss Fiends]].
* Several Fiends appear in places [[NothingIsScarier devoid of activity]]. Examples include the aforementioned Minami Sunamachi, [[spoiler:Kiccigiorgi Forest, the four-way intersection in the middle of a poison lake in the northwesternmost corner of Tokyo, and behind a door of an abandoned shelter in Kasumigaseki.]] Fortunately, they generally don't appear unless you're actively seeking them out, as they have a 1/256 chance of appearing every time you enter the area they reside in. Unfortunately, this only adds to the tension; after dozens of tries you'll probably stop expecting the Fiend you're seeking to show up, only to be [[JumpScare suddenly]] met by [[BossWarningSiren Burroughs warning you of a "very dangerous demon" nearby]]. In other words, it's the Uboa event from ''VideoGame/YumeNikki'', but with bloodthirsty {{Horsemen|OfTheApocalypse}} and other deadly entities ready to splatter your guts all over the street.
* Areas that have quiet or no music, no [=NPCs=], and demon encounters, due to NothingIsScarier of the "Wait for it" type. Examples include the underground areas of Kasumigaseki, the excavation area of Naraku, [[spoiler:any Ground Zero area in Blasted Tokyo, Blasted Shibuya, and Blasted Camp Ichigaya.]] Activating a quest to trigger one of the two quest tracks [[NightmareRetardant mitigates it]] [[SoundtrackDissonance somewhat]].
** The underground shelter [[http://www.youtube.com/watch?v=Hzoho3xd2-U music]], if you can even call it music. Nothing but windy ambient sounds. If you ever want to give yourself the chills, lock yourself in a dark, empty room while listening to this track on repeat.
** Camp Ichigaya [[spoiler:in Blasted Tokyo]] has [[http://www.youtube.com/watch?v=92HwM11d2FQ this]] faux-music, which has the sounds of howling sounds and machine ambience. It becomes a creepy example of a RewatchBonus because it and the Ichigaya theme [[spoiler:in Infernal Tokyo]] share a {{sampl|ing}}e.
** For that matter, areas that are all of the above, but have ''no'' demon encounters, due to the "nothing at all" type of Nothing Is Scarier. Examples include [[spoiler:the Blasted CDF base and Blasted Ikebukuro.]]
* The admission ritual into the Ring of Gaea at Tsukiji Hongwanji is all fine and dandy until [[spoiler:you get into the main hall, at which point the Gaea monk accompanying you reveals that he knows you're there on Tayama's orders and [[JumpScare suddenly opens a trap door below you]].]]
* During a quest to exterminate Wicker Hordes, [[spoiler:Nozomi constantly gets trapped inside one of them. The sound that plays when she gets put inside one is quite sickening.]] And recall that Wicker Man demons trap their targets inside them and set themselves on fire.
* While investigating the Counter-Demon Force base, you and your Samurai comrades enter a room, and are immediately greeted by the [[JumpScare sudden]] sight of what appears to the Black Samurai. [[InUniverse Walter himself is startled.]] [[NightmareRetardant Fortunately]], as you four find out, it was only the Demonica armor--one of many produced for the CDF--and not the Black Samurai herself.
