Who is Acme iku?
Acme iku is a voice synthesizer created by StudioS for the program Maidloid.
She is advertise as an "eroge" vocal synth: all of her noises consist of moans, screams, or yelps.

This, however, didn't stop people from trying to make her sing: one notorious example is Paraoka, who created an entire album using her samples
(and it's a banger).
This inspired multiple people to
make an utau voicebank with her voice (sometimes with decent results)

In January 23, 2022 an official VCV utau created by Kanna was officialy released in collaboration with StudioS.
She's now consider both a MAIDloid and an UTAUloid, even though the distribution of the VCV voicebank ended at the begin of 2023 after Kanna got involved in some drama and disappeared.

All of their work and social media are gone, but i managed to save two covers made with a beta version of Iku's official VCV.

Now that i infodumped enough...
I remember discovering her throught a song who used an another voice synth made by the same company and after that i fall into a rabbithole where i discovered like...
A tons of utau voicebanks that were created for the intent to imitate Iku and for some reason i can't escape it.

Talking about her voicebank, she has tons of problems: when she sings too high she sounds like she's dying, when she sings too low she sounds like a frog, most of the songs doesn't fit her at all and no one knows how to tune her, but i can't help but find her intriguing.

I think that despite all of her flaws, she's an interesting voicebank with a really cool design (her outfit is inspired by sushi) and i can't help it, but i love unpopular characters.

And i think you won't belive me how happy i was when i realized that her VCV utau voicebank was real (and in development).
