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.

While Deino ( AKA Deino 3330 ) is more of an artist than a producer, he does have a Youtube channel. And his videos are made in the same Surreal Horror style than the works on his Deviantart gallery, as the examples below clearly show...

  • Machine Muzik. Seriously. There's a reason it was 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").
  • Deino 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. It certainly doesn't help that the video's filled to the brim with what appears to be human-mantis hybrids.
    • 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.
    • The premise alone for the video is horrifying even when its allegories aren't considered. If you aren't aware of what the song is about, you're essentially watching a girl who seems to be trapped in some kind of dystopian acid-trip hell trying to fight this body-rotting disease which distorts and mutilates her, eventually consuming her. It not only looks grotesque, but painful.

  • "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 卍 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 creepy 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.
    • There's also the fact that Len suddenly has a hook for a hand after he becomes the new captain. Did each new Captain Hook have to chop off his own hand to play the part!?
  • The fates of the Messiah's companions in Blessed Messiah and the Tower of AI: Kaito is drowned in the sea, Meiko is burned up by hellfire, IA drops to her knees in a deadly drought, Mayu is eternally trapped in darkness, Gakupo is swallowed up by the earth, Gumi is incinerated by lightning, Luka is ripped apart by gale force winds, Rin is frozen to her core, and Len is forced to crawl through fire.
    • Near the end of the song, we see the silhouettes of the companions experiencing the so-called "blessings." Due to being silhouettes, we don't see many of the gory details, but saying that they look like they are not having fun would be a huge understatement. The worst one would have to be poor Mayu, who's shown holding her head and screaming in agony. This coupled with the wording to her "blessing" ("losing my mind in an endless darkness") implies that said "blessing" didn't actually kill her...
  • Sister’s ∞ mercY has plenty of creepy, jerky animation and Nightmare Face going on in its PV, but the plot of the story is just as chilling. A nun comes to town one day, offering tea that can grant wishes to those who drink it. It doesn't take long for the townsfolk to be subsumed by greed and lust, making all sorts of selfish and disgusting wishes, their tea-fueled fervor highlighted by the song's frantic big-band style. (There's an implication that the nun is making money off this.) Eventually, though, the nun decides that there are other "flocks" to be "saved", and drowns the entire town in her magical tea! An unspecified time in the future, a man in dark clothing wanders into town, and wonders: "Did they die happy..?"
    • The answer song reveals that the aforementioned man is actually a vampire. Was this all a Mercy Kill to prevent the vampire from feasting on them?


...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 Madness; Because of Her Knowledge. The fan artists are of no help. At the very end of a fanmade PV "Dark Woods Circus" she's become part of the circus. And then she hands you a flyer...
    • The novel dives into a more disturbing truth. the Circus cast is mostly made up of undead people. The diva was murdered by her crush, the twins were abandoned and fused together. The guy who eats cold stuff? He's a werewolf and he just get's kidnapped out of nowhere.
  • Contrary to popular belief, Machigerita has gone on the record on his blog stating that "Madness; Because of Her Knowledge" (or, as another translator called it, "Wide Knowledge of the Late, 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?.
    • The singers are credited as "the patients in the mental asylum". If the correctly translated title is anything to go on, it's a case of Go Mad from the Revelation. What that revelation is however remains a mystery.
  • 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 (originally made as a sequel to "Dark Woods Circus") is about a young girl in hell. 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, Broken Human 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 both, knowing Machige. Listening to the song with that knowledge alone is unsettling in itself, but the PV isn't much better.
  • 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.
  • Greetings from the bottom of the Well seems to be about either children or evil/vengeful spirits trapped in the bottom of the well, and how much they hate you. How it's sometimes black and white, or the hand that grabs you at the end doesn't help.
  • This song is surprisingly on its own not that terrifying, and appears to describe a very, ahem, amorous Miku talking about her desires and what she wants from her lover. The video however...

  • 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 two girls, Mai and Akari. Mai gets kidnapped by Akari's clan and becomes a cannibal after eating human flesh, and that's just the beginning! The 8 songs in the series dictate the lives and disturbing events of these two girls, as well as another set of Miku/GUMI characters and an Amanojaku played by Rin. Multiple other characters outside of the songs and media forms intertwine to form a truly gruesome story of the lion and the kitsune.
    • The worst case offender in this series is "The Spider and the Kitsune-like Lion", where Miku is captured by GUMI's clan 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. It's currently Masa's most popular video, with FOUR different PV's for different versions of the song.
    • 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: "On My Seventh Anniversary", "Me And a Heart", and the finale "To Celebrate You Two, I'm Here." These songs tell a story of two sisters— one older and one younger. The younger sister, Amaterasu, stabs and kills her older sibling Tsukuyomi over a petty dispute. This forces Amaterasu to impersonate her deceased older sister to cover it up (On My Seventh Anniversary). 12 years later, Amaterasu starts to feel strange. She's been picking up her dead sister's mannerisms, and sometimes forgets who she really is. She wonders— am I the older sister after all? She doesn't understand this strange phenomenon. She then realizes that her sister's spirit is possessing her. She wonders if she even killed Tsukuyomi at all, and begins to believe that she is really the original older sister (Me and a Heart). When Amaterasu turns 20, she decides to shed her guise and become herself again. She can't. She inevitably finds herself looking in a mirror with scissors in her hand, half of her hair in her style and half of it in Tsukuyomi's. She hears a baby's cry and realizes that the spirit of her sister is in her belly. She doesn't take it too well. The worst part is that the entire thing was foreshadowed from the very first song.
  • Another trilogy Masa made is Maha's Story, and it is equally as horrifying as The Sisters Series. Instead of traditional Japanese nightmare fuel, Masa opts for a more modern style of horror. The three songs, Enkantada, Chinese Dogma, and Mentalism Maria, tell the story of a violent gang and the deplorable things they do. Mentalism Maria focuses specifically on Maria Kanazaki and how she became the gang's 'false prophet'.

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.
  • Brainwashing Technique of the Monkey Dance (epilepsy warning by the way), which is more or less a half musical clusterfuck describing how despite humans seeing trained monkeys performing for food as cute or silly, we are still no better than them and in fact may actually be worse.


Akt Productions


  • 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.
  • LOLOLOL. The music is extremely subtle, mocking in the beginning, and the video itself is full of eerie imagery. The chorus itself is loud and alarming (a warning to anyone with their volume on high), and the beat is rife with tension. And during the middle of the song, the vocals are gone but you can vaguely hear someone droning "Stop"... It's unsettling, and that's not even on the subject of the lyrics...

  • 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 PVs 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 (updated version) 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 being in a total panic while running from demons. Miriam, a nun, believes that it's the apocalypse. Lola is suddenly attacked in her own home. Big Al, a doctor, tells a wounded Leon/Sweet Ann 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 can treat). Sonika/Sweet Ann is lying in an ambulance/the hospital and implied to be dead at the end of her verse. Eventually 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".

  • 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. Incidentally, you know how the song seems to have a strange voice saying nonsense toward the end? It's a backwards message. Give it a listen, if you want. But only if you're able to stomach an excerpt from Albert Fish's letter to Grace Budd's family describing how he killed and ate (But didn't rape) their daughter.
  • The Experiment is but another creepy one; based around the 'Russian Sleep Experiment' story, complete with what sounds like rasping breath and rather unnerving lyrics.
  • 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 story has many versions, but the gist of all of them is a woman who lost her children and killed herself... after going mad and killing the kids herself for some reason or another. So now she weeps eternally, looking for her lost children and if she finds a child at night, she kidnaps them, then, weeping, realizes they are not hers and drowns them.
  • Halloween Candy (MAJOR DISTURBING CONTENT WARNING.) You were expecting an innocent yet creepy halloween song? Too bad. The cheerful tone does nothing to mask the fact that it's a song about a child molester looking for new victims. You know a song is gonna be disturbing when its opening lines are "The friendly child molester"!
  • The recent collab between them, "Leech Boy" is a dramatic, unnerving tune about a boy with leeches "dotting on his face" (likely a synonym for indoctrinating bad beliefs), which ends with him BURNING DOWN A CHURCH. And the horrifying reveal of the boy's face near the end doesn't help. Especially when it's shown close up.
  • "Rust" is his collaboration with Tsus for Project Sonata, and it details a girl (represented by the robot in the video) planning to hurt the person she loves, whether out of desperation or spite. It's still creepy both ways. However it is implied that at the end she lets go of her vengeance and moves on.
  • 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.
  • 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 LaLaVoice, 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)
      • Even with the above spoiler the video is at least unsettling when you pause prematurely. She looks right at you if you pause the song outside the aforementioned screen wipes.
      • Even the lyrics do nothing to take the edge off, telling a story of a girl that decides to kill her father for killing her mother, then deciding to kill herself after she realizes that she's become just like him.
    • 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
      • The song itself is also quite unnerving and frantic. And just like ItaiAtashiAshitaAitai, the lyrics are no better. It seems to be about the Japanese urban legend of Mary's phone call.

Ghostie/Marz Mitzi/GHOSTnote 
  • "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, .flow, so to those who've played or even heard of the game, you can already tell what to expect.
  • GHOST decided to remake one of their songs "Housewife Radio" into a series. ** The first song, Rotary Dial, focuses on a woman named Frances Elsner, who is forced to raise her son Henry alone after the boy's father leaves her. Already emotionally unstable due to her un-diagnosed colorblindness making it hard to live alone, the lonely mother abuses her son emotionally by controlling his life and by reminding him that they will both die one day, and that she can't wait for it to happen. Henry is able to escape his mother with his childhood sweetheart, Nancy, who has Synesthesia. Once they marry, he's able to cut his mother out of his life.
    • But it doesn't take long for Nancy to start becoming uncertain that Henry will stay with her, and she becomes increasingly paranoid that he'll leave her like he did his mother. This becomes a Self-Fulfilling Prophecy in Black & White, where Nancy's behavior brings back memories of his mother and he prepares to leave her one night. At 2:15, you see a pair of arms wrap around Henry... and one of them is holding a knife. Then, the video just... distorts so you can barely see anything. According to the old summary, Nancy wakes up as he's leaving, and reaches for a knife...
    • In Housewife Radio, Nancy keeps going about her routine until she comes to her senses and realizes what she's one. It ends with her being Driven to Suicide, and the summary notes that police were called to the house after neighbors hadn't seen the couple in "a month or two", and according to the police they'd been dead for about a month and a half. In summer. It's even noted that the bodies aren't identifiable by sight.
  • HYPERDONTIA and its prequel, NOVOCAINE, tell the story of a malevolent dentist and their traumatized patient. The drilling noises/footsteps before the songs actually start may already freak some viewers out, and the droning repetition of the lyrics don't help. And the wet sound of the dentist ripping the patient's jaw off in NOVOCAINE...

  • Coin Locker Baby. While the subject matter is quite dark, it's the ending that turns the song into pure Nightmare Fuel. People have theorized that the sounds are from the vengeful spirit of the baby trying to get out of the locker.
    • If you look really closely during that final scene you will notice there appears to be something invisible moving across the screen, and if you pause at about 4:23 right before the video ends, you will notice a pair of eyes are staring at you.
  • Eraser Girl. The song seemingly speaks of two girls who have fallen in love and are paying for it due to the standards of the world. So they pretend they aren't in love until their secret is found out and they are rejected by society. The ending to this song is rather abrupt, which isn't nightmare fuel on it's own, until you think about the last lyric of the song talking about the view of the upside down scenery...
  • Scrumize. The lyrics to this song are quite unsettling (common interpretation being that Scrumize is told from the abused person in an abusive relationship), however it's once again the ending of the song that really makes this nightmare fuel. The song ends with a piano playing a simple melody which becomes heavily distorted and jarring as it plays it again and again.
  • Then there's Suji, a response song to Scrumize, told from the abuser's point of view in an abusive relationship. The song's lyrics are extremely disturbing, the narrator of the song wanting to do... Unspeakable things to the corpse of the character from Scrumize (who seems to have been murdered by said narrator). It doesn't help that the song seems to imply that the nature of the relationship between the Suji and Scrumize characters is pedophilic.

  • "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.
    • Now there's a third and presumably final installment called "Father", based on the sixth and final installment of DHMIS. It illustrates Roy's abuse of Yellow Guy very well...
    Roy: Have you learned your lesson?
    Yellow Guy: Yes I have.
    Roy: Will you disobey me?
    Yellow Guy: No I won't.
    • One of the lyrics is "Mother knew best but father took her place..." which begs the question: What did Roy do to Yellow Guy's mother?
  • One of the producer's lesser known works, "Regular", is based on a short that would later spawn Regular Show. The video starts off in an innocent-looking landscape. As chibified, humanised versions of Mordecai and Rigby travel through the landscape, it slowly turns from mundane to utterly horrifying. What's more, the lyrics, while not quite as horrifying as in Creeper-P's other works, imply that the singer (most likely Mordecai) is utterly terrified of the life he lives in his acid trip.
  • And then there's "MOMMY", a song based on a My Little Pony: Friendship Is Magic Creepypasta called Lil Miss Rarity. Even if you know nothing about the pasta, the blinking eyes in the PV, as well as the vague lyrics, can still send chills down your spine.
  • They now have "Static Screens", a song about Candle Cove. Yes, THAT Candle Cove...
  • "Tightrope", sung by Cyber Songman, ends with a Jump Scare followed by eerie droning music...the Jump Scare in question? Songman's character falling to his death.
    "I know that if I fall, it's my fau-SPLAT!


  • "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 Ie no Ura de Manbou ga Shinderu-P is a deceptively cute song about a girl (Miku) who 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.
  • The most well-known fanmade PV of the song 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 sacrifices 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 assertion 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.
  • 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.
  • 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.
  • Teratoma is Gumi at her absolute most terrifying. Teratoma is a tumor made of embrionary tissue.
  • MOL-P's "Pilom-San" (or "Mr. Pilom") is pretty much "Nothing Is Scarier" in song form. There are no lyrics besides Miku yelling "Pilom-san!" and occasionally a droning/fluctuating "ahhhh..." and the only image is the titular character (who clearly came from deep within the Uncanny Valley) standing there and occasionally looking at Miku when she says his name. The clincher? Nothing in the PV or song ever even comes close to explaining who or what "Pilom-san" is. He doesn't even kill anything or lunge at the audience, he just...stands there, Slender Man style and stares off into space with the single most unnerving smile one could ever have.
    • Just when you think the video only loops between him looking away and to the screen, at a certain point Miku called him and, instead of the usual Aside Glance, he gazed directly into the screen. The change was so sudden, and while it isn't really a Jump Scare, that gaze (which lasts for 5 seconds, by the way) will give the feeling that The Fourth Wall Will NOT Protect You.
  • Chanagi-P's Onii Yuukai at first seems like a really weird story about how Kaito's three sisters (Luka, Miku and Rin) want him as their boyfriend. They all seem to give up and satisfy themselves with fantasizing about it instead since he obviously doesn't feel the same. But then they dare to finally enter his room and you only hear him scream. Everybody wonders where he has disappeared to by the end of the song while the sisters all disappear into his room...
  • SeeU's Hide and Seek is about a young boy hiding in terror from his sister while the sister has fun singing about how they're playing Hide and Seek and how she can hear his running footsteps and see his hair peeking out. He finally hides underneath the table of his room, but she finds him with a Slasher Smile, claiming that now he is 'It'. He kills her and when he turns around, he has the black eyes of his sister and stares right at you.
  • Kamiyanagi's Scissorloid is about Miku who's feeling extreme jealousy for the attention that Luka is getting from Master and how she plans to kill her. When getting the chance to cut Luka's cables, Miku hesitates as she starts crying from remembering their good times, followed by a cheerful Luka waking up, mentioning how she loves Miku and is grateful for being her small sister before she adds Just kidding and stabs Miku with a knife, declaring that she felt the same jealousy and now can have Master all to herself.
  • VocaLight's cover of "Dancer in the Dark" that features multiple singers...and also adds in samples of what sounds like street warfare and screams in between verses.
  • Limelight has a very disturbing presentation.
  • That happy child/Anoko na shiawase ga is a song told entirely through shadow puppets, with an eerie melody and lyrics, which is only fitting. After all, it's about Cronos eating his own children, and the last of them taking his scythe.
  • "Splatter Party" by Camelia is about Miku committing mass murder with a chainsaw.
