Nightmare Fuel: Vocaloid

Since Vocaloid is pretty much a blank slate for whatever the composer decides to make, many of them can turn out differently than the next. These composers and songs just... decided to try and scare you. Fortunately for them note , these songs did.

    open/close all folders 

  • Machine Muzik. Seriously. There's a reason it's the page image. Just see for yourself.
  • Then watch the sequel, Nehanshika. One attempted translation made a couple of lines potentially worse ("We can account for e-e-e-errors"; "Now that you're dead you sing Nehanshika-hanshika").
  • The creator, Deino (known as Deino3330 on Youtube), was also behind this little nightmare. The song itself isn't Vocaloid, although the video does involve Calcium. Character's named Calne Ca, with "Ca" pronounced as separate letters, and is shown in the picture above.
  • BitCrushe isn't as bad as the above videos, but it's still extremely eerie.
  • "Bacterial Contamination" (or Saikin Osen). The song is about an unpopular girl being mocked and bullied by others, in turn becoming a bully herself in an attempt to make herself feel better, and then committing suicide to try and get away from the "infection." In the end, she states that, even though she could die to get away from the suffering, she still couldn't even die with dignity because of the things she'd done. And the singer herself is the aforementioned Calne Ca.
    • The English dubbed version (yes, it has been done) is arguably even worse . Especially the ending, where you hear the singer laughing quietly. She then says " sayonara " then devolves into insane laughter. Watch it here.

  • Bad End Night. Even though the song is fairly up-beat and jazzy, it is actually quite sinister. A girl (Miku) is lost with a letter to go to some mansion. She finds it and is greeted by the other Vocaloids. Later, she tries to go to sleep, only to find that no time goes by. She runs away, only to find graves. She finds that they are pretty much planning to kill her. In her fear, she pretty much kills them all. And then the final lines...
  • The P.O.V. Sequel, Crazy Night paints the house's residents as much more sympathetic, but is still quite sinister; turns out, their clock stopped because Miku interrupted their play and tore out the page that led to the ending. It turns out that she had to kill them to get to the ending. After doing so, however, she finds that she doesn't like the ending. As the family goes on to the next cycle (as there appears to be a time loop going on) Miku runs after them, begging them to give her another chance. They tell her that there isn't enough time but she'll "have another chance tomorrow", implying that she is now trapped in the same loop as them forever or at least until the chain is broken.
  • The third installment, Twilight Night is more confusing and even darkly humorous than scary, but it still has its unsettling moments. For example, when the inhabitants find that the last page of their script is missing, Rin and Len say this:
    Rin and Len: Not good? Not good! Ah hahaHAHAHAHAHA!!!!
  • The "True End", "Everlasting Night" ends with Miku having to kill herself to end the loop.
  • Karakuri Burst is a loud and violent song with frightening imagery, Nightmare Faces, lots of blood and a high pitched scream (or a loud burst of static) at the very end.
  • Portrait of the Pirate F is, though tame by comparison, a decidedly crepy spin on Peter Pan. To wit, a bored kid (Len) one night wishes to stay a child forever. Enter Rin as Tinkerbell, who takes him to Neverland. There, he first has loads of fun, then defeats Hook (Kaito)... and starts to get bored. He goes to the pirate ship and finds Hook's journal, then decides to take over the ship and the role of Hook. In the end, we see flashbacks showing that Kaito's character was brought in by the fairy the same way Len's was, then we see the green shoes of a new "Peter Pan" and Miku as Wendy. Apart from the obvious question of just how long has this been going on for, the creepiness factor is upped by Len's tranformation into Hook and his first actions: he attacks the indians and others with great relish, he admits he has become a greedy and cunning person who can't go back and is still obsessed with a never-ending dream, and his reaction to the appearance of a new "Peter" is a Psycho Smirk.


...You know, let's just say most of the songs by Machigerita-P (except for a couple of surprisingly cute songs he created for Miku) are made to scare you. And horribly scare you they do.

  • Dark Woods Circus and Wide Knowledge of the Late, Madness. The fan artists are of no help. At the very end of "Dark Woods Circus" she's become part of the circus. And then she hands you a flyer...
  • Contrary to popular belief, Machigerita has gone on the record on his blog stating that "Wide Knowledge of the Late, Madness" (or, as another translator called it, "Late Night Madness") is not, in fact, related to "Dark Woods Circus," and is a standalone song. Arguably, this makes it even more disturbing— because if not the circus's precursor, just what in the world is it about?
  • Rotten Girl, Grotesque Romance. It's basically about a very jealous stalker girl, who spies on the object of her affections. When she realizes that person is seeing another girl, she goes insane and plans to kill the girl and send her dismembered in a box to the person. And possibly kidnapps and murders them. That, coupled with the audio, piano, and random screeches in the music, makes all the more horrifying. It gets scarier when you listen to the Rockleetist version, where you can actually understand it. Oh, and don't forget the picture of Miku in the video. And the sound of her cutting off a kitten's head to give to her boyfriend. And as if it couldn't get any creepier...someone has managed to sing an English dub of it...and it happens to be rather awesome yet terrifyingly disturbing at the same time: Click and behold. And here's a lovely PV.
    • If you think about it, they probably weren't ever together to begin with...
    • The PV has the stalked boy keep the corpse of the murdered girl in his apartment for days. He even brushes its hair.
  • Red Swamp Bottom is a sequel to "Dark Woods Circus", and is much, much scarier. It's about Miku in hell, for god's sake! Special mention has to go to the tortured screams in the beginning and this particular set of lyrics:
    It hurts, my skin is burning
    My intestines are being dragged
    Now look, rotten fruit in my melting eyes
    Leave no trace of themselves
  • Hateful Wonderland. The video's artist is the same from "Rotten Girl, Grotesque Romance," so the imagery is quite unnerving...
  • The Full Course For Candy Addicts. "I love you so much I could eat you." The song is about her describing what her lover tastes like. The giggle at the very end does not help.
  • Once again by Machigerita, Human Destruction Machine. The scary thing? The translated lyrics are most likely about prostitution and abortion. Now available with proper subtitles.
  • Machigerita-P's done it AGAIN, using either Miku Append Light or Miku Append Vivid, in "Shukujo Berry no Tsukurikata", also known as "How to Make A She-trawberry". And it's most likely some kind of unholy cross between horror and porn from the lyrics. It's either about well... rape, or about someone eating a strawberry cake. Probably the former, knowing Machige.
  • Sweet Poison Factory by Machigerita-P. Your Mileage May Vary, but if the lyrics don't scare you, the images are enough to overstimulate your senses... (Don't watch if you have epilepsy or if flashing lights give you migraines.)
  • Okaasan is the undeniable master of all HONF for Vocaloid, hands-down. Lyrics are in the comments.
  • Gyakuzai Koushinkyoku. The lyrics are very confusing, but fans have theorized out that Kaito and Miku were in a relationship, but then he dumps her(saying that 'if a toy gets old, just throw it away') for Meiko. That's not the Nightmare Fuel. The Nightmare Fuel is that Kaito then murders her for no real reason and manipulates Meiko into ignoring it. The ending implies that he's going to do the same to Meiko if he sees someone prettier. And that's not even getting into the really creepy Psychotic Smirk in the PV.
  • Strange Masquerade Halloween. Upon reading the translation, the story goes like this. A group of people were invited to someone’s house for a Halloween party. Their invitations (which the song says “has an address, but no sender”) tell them to cover themselves with a mask so their wishes will be granted. At the party, there is banquet of food, sweets, drinks, and, well, something censored, as we see blurred items among the food floating down the screen. Then, the song talks about the guests spending who knows how long dancing, eating, and obtaining sexual pleasure. And then… “The mask – I –can’t – take – it – off! Aa – aaa – aaa – aaaa!” Just then, everyone changed into monsters (“squirming in pain while laughing”), each one resembling the masks they wore, while the owner of the house watches while laughing.

  • Masa used to be a relatively unknown producer, but those who encountered some of his music will be rattled. While the videos may be creepy, having the lyrics translated make it all the more unnerving.
  • Masa's best known series of songs, dubbed "the Onibi series", seems to be telling the tale of a cursed family— a feudal lord tortured one of his servants (Miku) to death for entertainment value, and she cursed them and seemed to become a demon. Her curse drove his descendants (Gumi) to madness, and they engage in all kinds of debauchery— cannibalism, torture, necrophilia, and other various depraved acts of sex and violence. The Onibi songs follow that lineage and their... "activities."
    • The worst case offender is "The Spider and the Kitsune-like Lion", where Miku is tortured to death and Gumi is turned on by her pain. It's highly graphic and very not safe for work. This song was set to private on Masa's Youtube channel (ell182a) and removed from Nicovideo for good reason.
    • The Fox's Wedding (not to be confused with the one listed below by OSTER Project). The way the lyrics are sung feels like Madness Mantra. Turn on the captions.
    • And then there's this one which is about a vengeful spirit trying to kill her murderer ( as usual, they're respectively portrayed by Miku and Gumi ). The chorus and the occasional ghostly moans make it worse.
  • The Sisters series, meanwhile, consists of a trio of songs that tie together: "My Seventh Celebration", "Your Heart And Mine Becoming One", and the finale "I am the Celebration of Two People." They tell the story of a demon who was killed; the demon's soul was split and reincarnated into two young girls, a pair of sisters. Then, one day, the demon decides that it's time to fix that little problem. The final song reveals that the two sisters merge into one person. They don't take it too well. The worst part is that their eventual fusion was foreshadowed from the very first song.

mothy (master of the heavenly yard) had gotten a reputation from the Evillious Chronicles; it has its own "wiki", and most of his songs end with someone being murdered or worse... Has its own page here.

  • "Moonlit Bear" starts off with a woman finding these magical fruits in a forest, taking them with the goal of making her husband happy and encountering an evil bear who wants the fruit back. Sounds like a nice adventure story, right? Fridge Horror gets applied at the near end of the song when its revealed that the fruit are really babies and the bear is the distraught mother. Made even worse when its revealed that she MURDERED THE MOTHER TO STEAL HER CHILDREN. Fits into Adult Fear too.
  • While not as scary as some others, "Blood-Stained Switch is still pretty creepy. A girl talks about how her father was slaughtered by the machinery in the factory he works in, and later reveals that She had an alter ego that killed him out of revenge for being abused by him. The song ends with the girl exclaiming that she's not evil, and begging not to be given an injection.
  • Conchita, the Epicurean Daughter of Evil starts off innocently enough with the titular character (played by Meiko) portrayed as a Big Eater who specializes in unusual delicacies. Then she eats Kaito. And the other servants. Until ultimately, still not satisfied enough, she eats herself.
  • The Tailor Shop on Enbizaka sung by Luka Megurine. The song itself is about the titular tailor being sad as she sees her lover with various girls, mentioning crimes happening around the neighborhood. Finally, when a man is killed, she notes that the four people killed were a family. Poor Communication Kills doesn't even begin to cover it. Her "lover" has no idea who she is.
  • Wendy By Mothy well....we can already tell it won't be happy despite the cheery tune. With a girl trying to follow Peter Pan by jumping out of a window and dying, how could it be?
  • Flames of Yellow Phosphorous is a delightful retelling of The Little Match Girl where she burns down her father's house and is consequently burned at the stake for her crime.

  • Parasite. A hard, thrashing, dark metal song featuring distorted vocals and lyrics that are probably about mosquitoes that carry deadly disease... written from the point of view of the mosquitoes.
  • "Black Hole Artist," also by Utsu-P. Rin's face is horrifying.
  • "The Magic of Massacre". The song is about GUMI coming up with things of her own imagination, inspired by an egg in a microwave, including a hand with an eyeball in it that shoots lasers at everything and the fingers wiggle around and... eugh. The whole video would give one the creeps. At the end, the egg explodes INTO BLOOD and smoke fills the microwave. Fun, fun, fun!!
  • "Poster Girl's Prank". The imagery in this song's video is more tame than others and seems to be less explicit, and more dark-artsy. Miku. Rin, and GUMI are portrayed as idol girls with abstract artwork for faces. Burton-esque men in suits and ties with animal heads are also featured. The scary parts though, are some of the lyrics: while the first battery of questions from what appears to be an interview are innocent enough, they turn right around (An adoring male fan?/Bring him back home with me!", "What are your favourite foods?/The hands and feet!")
    • A girl is also implied to have been thrown away by the singers' employers, and "disappeared to the nooks of Edo". They tell about a girl selling herself out to prostitution because society is rough. The entire song is a protest against the J-pop machine, which is cool, but to someone who doesn't know about all that stuff it's just straight-up nightmare inducing.

  • Mother of Pearl Bones. With an unsettling PV, glitch parts in the vocals, and the unsettling lyrics, what's to come? Well, it's learned that she dies in a fire, a theory states, and her "lover" is dead, too.
  • Another great from Babuchan, Tears of an Artificial Eye (with subs) The song is apparently about A doll coming to life and killing its owner.

  • Calalini, written about and from the POV of "Jani". Possibly qualifies as a Tear Jerker as well.
  • This. It's a Megurine Luka song, in English, based on the following Rugrats theory: "The Rugrats really were a figment of Angelica's Imagination. Chucky died a long time ago along with this mother, that's why Chaz is a nervous wreck all the time. Tommy was a stillborn, that's why Stu is constantly in the basement making toys for the son who never had a chance to live. The DeVilles had an abortion, Angelica couldn't figure whether it would be a boy or a girl thus creating the twins."
  • This song about HIM from The Powerpuff Girls. The PV shows a silhouette that looks like Bubbles and her Octi doll is on the floor in front of her with HIM's sinister shadow radiating from it. HIM tells Bubbles "not to cry" and that he wants her to "smile". He then tells her to "give in to her fight" and "take the anger deep inside and bring it into light". at the end, his message gets more and more garbled and then he promises to Bubbles that he will give her anything she wants. He then tells her that she's "his to control"...and to "prepare to attack".

  • With a title like Hold, Release; The Rakshasa and the Corpse, what else can you expect? Hachi has officially stated that the song is about the supposed innocence of children, and how cruel they can really be... but that other interpretations could also be valid.
  • "In a Rainy Town, Balloons Dance With Devils," the demo form of the below "Ward Room 305," by Hachi, features an eerie, surreal sound and lyrics, and the PV has been animated to match.
    • "Ward Room 305", the completed form of the song, is likewise fairly nightmarish in lyrics, and the fan theories used to create the fan-animated P Vs are accordingly dark.

  • Engloids are not exempt from this. Big Al's Beat Beat Tick Tick. There's a line implying that Al fell from very high up, and then the realization that the picture wasn't him covered in blood from a murder - It was his OWN. He's laying on the ground DYING, and the beating and ticking is his heart slowly stopping as he does.
    Beat. Beat. Tick. Tick.
  • From the same writer, we have Halloween Requiem. A group of teenagers try to summon dead spirits but it goes horribly wrong and a bunch of evil spirits emerge from their Ouija board. The spirits are extremely offended at the fact that nobody is afraid of them because of Halloween and promptly start attacking people to "strike fear back into their hearts (and it's implied that their first victims were a bunch of trick-or-treaters). Leon is shown running from a demon and in a total panic. Miriam, a nun, believes that it's the apocalypse. Lola and her husband are suddenly attacked in their own home. Big Al, a doctor, tells a wounded Leon that he can't help him because "the hospital is overflowing" and that he should probably stay there because "it's safer there" and "free space is growing" (implying that more people are dying than he and Sweet Anne can treat). Sonika is lying in an ambulance and implied to be dead at the end of her verse. At the climax, something happens that causes the monsters to leave, but their fear remains in the world's heart as it's revealed at the end that due to the incident nobody celebrates Halloween anymore; instead, they celebrate the day that October passes. At the end, the Engloids give us some advice: "If you choose to laugh at evil make sure you think twice".
    • Koda-P recently made a triumphant return from hiatus with a remake of Halloween Requiem, with improved vocals and a much more well made (and nightmare-inducing) PV to boot! Watch it here: Halloween Requiem (2014 version + PV)


  • Even Yuki isn't exempt from horror songs. This artist has apparently done a series of Vocaloid noise songs. Including more by Yuki. absence seems to most resemble a traditional song, but it's still incredibly oppressive and hopeless-sounding. The translation of the lyrics doesn't help. "That child isn't anywhere... that child isn't anywhere... that child isn't anywhere... that child isn't anywhere..."
  • crushed Mary is... something else, that's for sure. There isn't much in the way of lyrics, so interpertations are sparse, but the "music", if you can call it that, is horrific and cacophonic. This is one you don't want to listen to with headphones in.

Steampianist & Morbid-Morsel
  • From Steampianist and Morbid-Morsel comes Twaddles of a Flue Faker. Sung by Oliver, it gives the POV of a young chimney-sweep from England. Combining a creepy black, white, and red PV with strange, spooky music, the flatness of Oliver's voice and lyrics that are a combination between Tear Jerker and Nightmare Fuel, the overall effect is highly unsettling.
  • These two have teamed up again for another round of nightmares in the form of Secrets of Wysteria, based off of the deeds of notorious serial killer and cannibal Albert Fish. Once again, the PV is what makes it truly terrifying, alternating between disturbing black and white imagery of gore and body parts and frantic scribbling over a red backdrop. The eerie slow tempo of the music combined with the creepy music box and Oliver's emotionless vocals really make this one of the more terrifying Engloid songs out there.
  • Yet another terrifying masterpiece from them and Momocashew has surfaced for the "Assorted Vocanuts" album: The Perfumer's Perfect Fumes. Oliver assumes the role of Jean-Baptiste Grenouille from Patrick Suskind's "Perfume", singing creepily emotional lyrics that are halfway between "crazy stalker" and "God complex", to a roaring metal track. The images in the PV are fairly benign for the subject matter, however... Until the end. Dear GOD. (WARNING: It's extremely gory. Don't look if you're sensitive to that kind of thing.)
  • Have you heard the story of La Llorona? Then this song is an excellent starting point. Oliver & Gumi as creepy children choir and Maika as the titular ghost/monster... Nice company to enjoy!
  • The lyrics to This is the happiness and peace of mind committee, by Hatsune Miku. It's about Miku wondering why everyone in the world isn't happy. So, she seemingly brainwashes everyone into being happy by... singing. Her face is in the video is quite an unsettling slasher smile too.
    • Here, here's Rin's cover of it. Good night, kids! Oh, and, how would you like to die?
    • The English cover is somehow even worse...
  • By the same person as above, we have Miku's The Path to Eternal Happiness, I found it. It starts out pretty cute with a Bride!Miku who tells a story of newly-wed couple on a beach and the bride asking if the groom knows about 'a paradise to the south, the city of hopes where wishes come true'. She then says that she found a way to go there and disappears to find immortality. Then we see another Miku who acts like a host and is most likely the ruler of the place. Bride!Miku then has to play 'The Original Sin Game', while she plays we see panels with words flashing by, but you have to pause them at the right time to actually be able to read them. Miku wins and we cut back to the beach and we learn see that the Groom always continued to wait for her at the beach, until his death. She apparently wrote him a letter, but it was never read. Then we go to the game show again and see that the host is surprised that Bride!Miku is there again. This time Bride!Miku has to play 'The Game of Guilt', which she wins again and as a reward she becomes a zombie.

  • Though it isn't truly Vocaloid-based, the artist watashinokoko creates noise songs using the program La La Voice, a technical predecessor to Vocaloid. Many of these songs are incredibly nightmarish. Examples include:
    • Like You. The song starts out very quiet, but then the noise kicks in. And the content of the song and video itself does nothing to take the edge off; the song starts off normally enough (for a noise song,) a flickering image of a girl in the background, and then words appear on the screen, requests (ranging from "fuck me" to "listen [to] me.") And then it changes to "Kill me." Repeated over and over and over again, as the image of the girl in the background flips upside-down and starts to change, her eyes darkening until they're entirely blacked out.
    • Complex. A dark, mysterious, and discordant song with surreal imagery presented in black, red, and white.

  • 'Wakako and Ruriko's Breaking of Toy Blocks'. It can be found here. The entire video is a rainy night scene with two people, one of which looks a bit taller. And then at the end you see the knife in the little girl's hand is 'DRIPPING' with blood.
    • For those of you who want the interactive link: God save you if you choose to press the button after 'Sayonara'- THIS is why it's Nightmare Fuel, for the skeptics, if you will...
    • The sequel, ItaiAtashiAshitaAitai is also pretty creepy. Like above, what makes it Nightmare Fuel is that special little bonus you get when you attempt to pause when the screen wipes out (0:23 and 2:52)
    • And on the subject of Chad's fun little videos, If you decide to watch Incoming/Outgoing , whatever you do, don't:
      • pause for more than 30 seconds
      • pause at 0:24
      • pause between 2:01 and 2:02

  • "Project Distortion", in which Maika, Mayu and Gumi perform a rather ambiguous surgical procedure on Yohioloid, ending with him lamenting the loss of humanity. This gets worse if you look up some of the operations they mention (which you don't want to do if you have a weak stomach).
  • "Oxidation and Dream Monsters", which was based on the Yume Nikki fangame, dotflow, so to those who've played or even heard of the game, you can already tell what to expect.

  • Jisatsu Shoujo, a Miku song by Daijoubu-P, whose title translates to "Suicide Girl". It's intentionally discordant, and you can practically hear how fragile Miku's mental state must be. The PV isn't much better, depicting a skinless Miku whose face appears to be frozen in a scream of agony.
    • There is now a translation of the above song, and it's everything you'd expect and more— although some fans in the comment sections have theorized that it might actually be a joke song, parodying other, more serious Vocaloid metal and noise songs with dark subject matter such as suicide and bullying. Either way, it's still terrifying.
  • "A 13-Year-Old Killer," by Kagamine Rin. The subject matter is upsetting enough, but the dark, creepy sound of the song and the male narrator that you can barely make out over the music barely helps. And the final spoken line of the song is chilling, once you put it all together...
  • This. It's a 30 second video of Miku repeatedly stabbing... someone. The amount of blood around and the sound that the stabbing makes both imply that she's been at this for a while, and she doesn't seem to be interested in stopping. Upon watching the making-of, it's revealed that the person that she's stabbing is Kaito. "Love is War" playing softly in the background does not help.
  • Tympole (Otamaru)'s face in the Pokémon Isshu Rap. For added fun, parts of the song were produced by Daijoubu-P and Utsu-P, mentioned above, and they stick to their usual styles.
  • Abre los Ojos ("Open Your Eyes"), in which Miku plays the role of a girl who, after being rejected by the man she loves, decides to make sure that his heart is hers ... literally.
  • Circle You, Circle You. If you don't feel like watching the PV, this image pretty much sums it up. Children dismembering each other for all of eternity.
    • Even moreso, the Creepypasta based on it is even more terrifying, with scientists performing horrible experiments on them (see the creepypasta Nightmare Fuel page for details)
    • Rockleetist's dub makes it even scarier, especially the last verse:
    Circle you, circle you
    Circle you, circle you
    Circle you, circle you
  • KAITO ga UNINSTALL: Kaito goes Yandere and kills the other Vocaloids so he can be his master's center of attention and affection.
  • Fear Garden, in which Rin sings about cutting the other Vocaloids' arms off and planting them like flowers in her garden.
  • The Purple Forest sung by Miku and Kaito. The creepiest thing about this song is that there is no ominous notes, it sounds sweet and pretty and lovely the whole way. The only way you know it is creepy is if you watch the video, and after that, the simple fact of such a pleasant sounding song with an ominous backstory is chilling. The story is about a forest that no one likes to enter. A traveler (Kaito) wanders in and meets a pretty young girl (Miku). She turns out to be a dryad who lures people to her, and absorbs them into her tree for sustenance. She does this to Kaito while he sleeps, while the whole time Kaito believes he's being taken to a paradise. And then at the very end of the vid, Miku looks right at you with the beginnings of a Slasher Smile.
  • We Were Friends Until Yesterday by Miku is a deceptively cute song about a girl that becomes friends with a weird sunfish...thing. Takes a turn for the worse when their food runs low and her "friend" starts to look more like food...
  • Prisoner and Paper Airplane ride on the anxiety caused by being permanently separated from a loved one. Except in this case, one part of the couple (Rin) is a terminally Ill Girl, and the other part of the couple (Len) is in a prison—no, a concentration camp. One with backdrops derived from Auschwitz. We first, in "Prisoner", witness Len being put to death in a gas chamber. Then in "Paper Airplane", we see Rin being put on gradually more life support, until she ultimately passes away.
  • Trick and Treat is about Miku being lured into a house in the woods by Rin and Len, and being drugged with candy to make her fall asleep. She wakes up sooner than they anticipated and suddenly remembers where she knows the pair from. They're her old dolls, which she abandoned after getting a new one. Once Rin and Len realize that she's awake, things get worse in a hurry. The twins want Miku's heart... and succeed in getting it.
  • The Riddle Solver Who Can't Solve Riddles is more than a little disconcerting, as it starts out with Len interrogating his sister, who apparently has murdered all the guests... but by the end of the video it's fairly obvious Len is the one who killed them all and he's about to do the same to her.
    • Followed by The Riddle Solver Who Won't Solve Riddles, in which Rin insists that Len didn't kill them. She piles on riddle after riddle, promising to trap whoever can solve the mystery in the world of their story.
  • Twilight Homicide Song. Meiko can be pretty scary too. And that mask.
  • SF-A2 Miki singing the Lavender Town theme, from Pokemon, a song frequently used or at least referenced in the horror stories of the Pokemon fandom.
    • Speaking of Lavender Town, the song Lavender Tone (sung by Yohioloid) goes more in-depth with the horror, referencing other Pokepastas like Ghost and Buried Alive. First-time viewers may miss the subtle Madness Makeover that he's going through as a result of playing the game, shown by his hair becoming more unkempt and bags forming under his eyes. The video ends with a picture of an open window, implying that he committed suicide.
  • "50/50," a Miku song about a girl who is jealous of her best friend Mari-chan's new boyfriend... so she cuts him in half so that they can share. "Mari-chan and I go halfsies on everything." Now available with English subtitles.
  • Despite its awesome tune, Kagerou (translation: Heat Haze) Days can be a bit scary to watch, especially the PV Version. The song is essentially about a "Groundhog Day" Loop wherein a boy is forced to watch his friend die in increasingly horrible ways, no matter how much he tries to prevent it. In order to break the loop once and for all, he goes back to the first death (the girl gets smashed by a speeding truck) and sacrifieces himself so the girl could live. And just when you think that all is said and done, the ending of the song shows the girl seemingly going through the same loop, only with the boy dying instead.
  • Here is You Are Mine, a Yandere Luka song.
    "I'll die...I'll die! just to get away from you!"
    Aw, why? Don't die!
    You know I will still own you!
  • Black and White Ward (also known as Monochrome Ward) is the story of science gone horribly wrong. It flies by so fast that you may not realize that Rin has swapped clothes/appearance with Len at the end. It ends with Rin dead, Rin's assertation that Len is still a nobody, and the words Congratulations "Rin".
  • Love Disease featuring Luka. Starts off as a peppy swing song about going on a date, until we learn that Luka was just daydreaming about the whole thing. Then she catches her love interest going out with another woman, which prompts her to Murder the Hypotenuse so she can have him all to herself, and at the same time that eyes-out-of-frame shot that's remained still the whole time zooms out to reveal a Slasher Smile with Ax-Crazy eyes. She stalks him and tries repeatedly to get in contact with him (and it's implied he's trying to get away from her). "If I Can't Have You" goes into full effect by the end of the song; it's implied she either kills him or rapes him.
  • Wonder Girl & Labyrinth Gate is the tale of Hansel and Gretel, and how they defeat the evil witch! Except that Hansel is a doll, the candy house is run-down shed, and the wicked witch isn't a witch at all. (Note: turn on CC to view english subs)
  • A Fox Wedding(not to be confused with the equally terrifying The Fox's Wedding) starts out as a typical Tear Jerker song…and then...
  • From JUSF Zhou Cun, a Luo Tianyi/Yan He song: Puppet Master: Finest Creation. It sounds jazzy and all, but... the PV begins with a disclaimer of sorts: Yandere, check. Representation of blood, check. Body parts cut to pieces, check. It's about a man trying to create the perfect doll from human parts and constantly being unsatisfied and hacking it up again. Said 'doll' is implied to still be alive.
  • This alternate music video for Kaito's cover of Donut Hole starts out as a simple Tear Jerker and then the second verse happens. And then things get even worse. Much worse.
  • "Rotten Rotten Zombie" has a PV that has Gumi and Cul as cute zombies and other cute monsters, that were, respectively, the wife and lover of a man who kills them both. Then they return from the grave and they "split" him between each other.
  • "Creativity" sung by Avanna and Kaito. It acts as a Villain Song for Sketchbook and Tony the Talking Clock from "Don't Hug Me I'm Scared". It summarizes them both perfectly and horrifyingly.
    • The same producer made another DHMIS-inspired song called "Ai" (Love). The description says that it's about an abusive relationship, from the abuser's point-of-view. Also, don't let the video fool you at first. While the little Shrignolds (butterflies) floating up and down the picture look cute, Chika's eventual Slasher Smile certainly isn't.
      • For those who are curious about what the song says, the producer has released an English version with Cyber Diva singing it. The lyrics... aren't pleasant, to say the least.
  • Cantarella is a difficult song to interpret, but some of the lyrics have very disturbing implications. It seems that many fans have caught on to Kaito's rapist vibes, as quite a few fanmade videos include him drugging and restraining Miku in an attempt to get her into bed.
    I now set up a trap to capture your captivated heart.
    There's no place to escape from this rusty chain.
    If I slip you into the deep bushes, you'll probably be violated by the scent of our mixing sweats.
  • Escape the Princess is about a princess (Miku) in a loveless marriage with an emperor and is secretly in love with the emperor's sister. When the sister marries and moves away, the princess falls into despair, starts seeing one of her ladies-in-waiting (Gumi) as the sister's lookalike, and then violates her, causing the lady-in-waiting to attempt to flee. The song itself is incredibly frantic and fast-paced with intense piano chords, making the listener feel the desperation of the lady-in-waiting as she attempts to escape. In the end, the princess catches her and it is implied that the lady-in-waiting becomes the princess' sex slave.
  • Coin Locker Baby. While the subject matter is quite dark, it's the ending that turns the song into pure Nightmare Fuel. People have theorised that the sounds are from the vengeful spirit of the baby trying to get out of the locker.
  • Slender Fortress has Shadow Miku, a totally black version of Miku with glowing white lines in her body. There are two Mikus, one real and one fake. The fake one is only black with white eyes and the real one is the former one with white lines. Once the real one detects you, you will have to sacrifice a teammate if you want to survive
    • The sounds they make are the most disturbing thing about them. The theme that plays when the real one chases you is especially creepy. If you look at the game's files,you will see that its an reversed version of "Triple Baka".
  • This English cover of "Story of a Poor Blue Rabbit". It manages to be creepier than the original song with the slow, soft singing, and the sound of a cutting knife in the middle.
  • "SHOTA=RELEASE", sung by Len. It tells the story of a boy who has fallen in love with an older man. The story is mostly told in the present, where Len is doing...something in a dark, quiet room. It quickly gets creepier when he makes mention of his lover's significant other, musing that she's in the way, and then cuts back to the present. It turns out that he's having sex with the older man and makes mention of wanting the man to rape him.
    • You don't see any of it, though. Just the room, and Len's changing expressions.
