And someone has to be turned on by the male vocaloids. There's the near (He's 14 and actually mentions that he's not a shota in gekokujou) shota Len, Kaito, the oldest of the vocaloids if you don't count Teto, and Gackt. Yes, Gackt, there is a vocaloid whose voice samples came from Gackt. Gackt.
Teto isn't a Vocaloid, she's an UTAUloid; and the oldest Vocaloid, as far as we know, is Big Al, who's 25. Still hot.
This troper adores Kaito, he's the resident bitch, tends to get dominated by the girls and has a 50/50 top-bottom chance with the the guys. His scarf is a perfect bondage item (tie him up? lead him around like a leash?), not to mention his adorable, slavish devotion to "Master". Even his Yandere side is kinky, loyal, blood-covered, just a bit jealous.
then there's Dark Woods Circus, Straitjacket, the glazed eyes of madness as he gives a tiny, hungry grin. Then there's the cannibalism, if you're into that.
Just try to get through this video without having questionable thoughts about Len. Or any of the other Vocaloids, for that matter.
Many fetishes in Vocaloid and (specially) UTAU; there should be a list only for these, they cover absolutely all bases. Yeah, even the Furry Fandom. And I'm pretty sure at least someone is turned on by Acme Iku. Not me, because I'm more into Kiyoteru. The suit and glasses...
Hatsune Miku Project DIVA 2nd allows you to pick your own pairings for the duet songs. And the game won't stop you from having your character's partner be a copy of him/her.
Luka will certainly appeal to those who prefer women to be more adult and well-endowed. She's also Tall Dark And Bishoujo, sports pink hair, and can sing in Japanese and English. Plus she has one of the deeper female voices in the Vocaloid lineup. And last but not least, one of her character items is a whip; cue depictions of her as a dominatrix.
The Madness of Duke Venomania has Gakupo as a duke with a large harem of Vocaloid women that he has sex with nightly. The video shows you enough of these nightly sessions to know they can't be doing anything else. If Gakupo himself doesn't turn you on, the artwork of what happens at night certainly will. Of course, there's also Kaito as a crossdresser at the final verse of the song stabbing Gakupo and killing him, so if you're into that sort of thing...
Dear god yes. And what about the star of the video, Gakupo himself? Long, flowing purple hair, frequently portrayed as naked-happy, and even when he's not... Is it right to have a sleeve fetish? Also, his eyes.
Something about Rin's voice in The Cursed Glases is very appealing... maybe it's because she sounds so pissed off...
Good lord how can this list not mention this song! If the fact that Kagamine Ren is being portrayed as a hot little playboy doesn't turn you on, then the fact that he is in the nude (or shirtless, or with his shirt open) for most of the song will. The image of him smiling, with the word "SPICE!" written on his arm is enough to make this Troper melt into the floor...and that's without mentioning his voice! As one YouTuber put it "Shit...I think I just fell in love with a 14 year old artificial voice program". Better words could not have been spoken.
Gigantic Girl. The song itself is a veritable anthem for giantess fetishists, but the accompanying video is the icing on the cake.
Alice Human Sacrifice!Meiko. A blood-spattered psychopath who cuts down anything and everything that comes after her or stands in her way. YUM.
Speaking of Grimdark!Meiko, while this troper considers it to be a GIANT turn-off, Conchita in Evil Food Eater Conchita is probably every vore fetishist's dream girl.
This image. If you're wondering, it's a picture of Gakupo in a tight, formfitting outfit that can only be described as his underwear. And there is a back view. You're welcome.
I'm personally rather fond of fan-made vocaloid Dell Honne. He's so...pretty, but also so mean looking, but his character description implies that he's a nice guy deep down. And his implicit kindness towards Haku and his woobieness. Yes please.
