Sayaka Keina


Shin (Original\2007)



Acme Iku (阿久女イク) is a Japanese MAIDLOID (メイドロイド) developed and distributed by StudioS, and was released December 27, 2007. Her voice is provided by the Japanese voice actress, Sayaka Keina (計名さや香; Keina Sayaka).


It is a voice synthesizing engine much like VOCALOID, but is made to create erotic sounds instead of singing. It can voice the 50 Japanese consonants along with several hundred terms to sound like a recreation of an eroge. There are a few extras, such as the ability to insert customized special sound effects. Acme Iku's voice can be used in games and animation and those works can be sold. However, it is illegal to distribute her full voicebank. There are exceptions with the Lite version.


The name Acme in kanji is the choice of corresponding pronunciation and has no valid literal interpretation. In katakana 'Acme' in Japanese literally means "orgasm." And Iku is a common erotic moan in Japan, meaning "to come, to orgasm." As such, her name translates into a sexual innuendo. Her name simplified in hiragana is "あくめいく".


She is a housemaid android who is meant to be a lewd and cute character.


Fighting Game

Iku was featured as a playable character in the Japanese PC doujin game Super Strip Fighter IV (スーパーストリートファイターⅣ). Her voice bank is used, and some of her attacks consist of use of her hair, she is able to use her hair accessory and throw or swing it at her opponents.[1]

Package details
Some have attempted to make her sing, and even proved successful by importing the Japanese syllables into UTAU. She is not meant for music however; like with the Macne Series you need to own the original voicebank to legally be able to use her as an UTAU. However, making an UTAU voicebank out of the lite version, which is free, of her original voicebank and distributing it is 100% legal.
Software issues as noted:

Her common UTAU voicebank users often come across is made from the lite version of her software, she has barely any clarity and is difficult for even native Japanese speakers to understand.

The majority of western UTAU users who manage secure the UTAU voicebank for their own usage do not own the original voicebank and it is estimated that the number of users who own it illegally is quite high. Part of the problem was that because other UTAU voicebanks are shared freely, they presume the same for MAIDLOID even though this is not the case.

Additional informationEdit


  • Those in the fandom that are aware of her have called her the perverted "VOCALOID"/"UTAUloid"/"x-loid".
