AiKO was introduced as the mascot of Animen and made her debut in 2012.[1] Since then, she received many promotions and merchandise, including the choosing of her name through a 2012 survey. Liang Xiao Miao was her voice actress for many years and a single for AiKO was released even prior to her Synthesizer V debut.

For Synthesizer V, AiKO was first demonstrated by Umine Kyo in a cover of "好想你 (I Miss You)" by Joyce Chu on December 7, 2018. She was said to be sweet, natural, and not difficult to use. Another cover was uploaded to bilibili on December 16. This time, it was "梦境小偷 (Dream Thief)", which originally featured Hatsune Miku.

While she was not included in the "Synthesizer V Production Release" on December 24, it was announced that she would be released shortly. This was later revealed to be December 28.[2]

AiKO was released alongside the license for Synthesizer V on Animen's web shop, ANiCUTE, on the intended date. She was also available at a 30% discount at the time.[3] Physical copies were also made available on Quadimension's Taobao shop for users in Mainland China.

On January 8, 2019 a demo song called "Something New" was uploaded. It featured Eleanor Forte as the main vocal and AiKO as backing vocals. The whole song was in English.


AiKO's Synthesizer V voice database was retired upon release of Synthesizer V Studio and was replaced with one that was compatible with the engine in July 2020.
