## History

### 2017

On November 13, 2017, the head of Beijing Photek S&T Development Co., Ltd., Ddickky, noted that people seemed to think that Xingchen was easy to manage because she was the company's only VOCALOID. He mentioned that he wanted to try to "have five to take care of" to see how challenging it was to manage more characters and asked fans to "stay tuned". This seemingly hinted that there may be additional characters aside from Xingchen in the future. Later that month, it was mentioned that because Beijing Photek wanted to save money to produce content, some big news would be announced at Quadimension Live Tour rather than a separate conference. This included new merchandise, official art, and if there was time, games or voicebanks. It was not specified if these voicebanks were for Xingchen or for any new characters. Details about the announcement are currently unknown.

### 2018

On April 14, 2018, Ddickky mentioned that the names and designs of the fire, earth, and air characters were decided. While it was not stated what this referred to, it was possible that these characters may be part of Xingchen and Haiyi's series.

On November 9, Haiyi mentioned some "younger sisters", possibly referring to the other elemental characters within the series though not explicitly confirmed.

### 2019

On February 1, 2019, Chiyu's name appeared in a crossfade video for Haiyi's solo album "Atlantis".

On March 28, Ddickky posted on Weibo that Chiyu, Shian, Cangqiong, two Xingchen voice databases, and an unknown male voice were moving over to Synthesizer V. On April 9, Chiyu's silhouette was shown. Her voice was showcased the next day, although she only sang in "Na"s. Another demo was released and confirmed to be written by kide.

On April 16, it was announced that Chiyu's voice database would be available for preorder starting on April 19. According to her product page, it was confirmed that she would release on April 30 as a digital download. It was revealed on her first demo that she was designed by Hanasa, ATDan, and Kurumimi. Her voice provider was confirmed to be YouMao UNEKO. She was released on April 30 as expected.

### Retirement

Chiyu'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. Physical packages were still available as a collectable item, but did not contain activation codes, thus making the product unusable.
