While celebrating the 5th anniversary of Yuzuki Yukari it was mentioned that the notion of making the next vocal was brought up. Having released all the planned vocals for Yukari both in Vocaloid and Voiceroid, the issue became a more serious one. Bumpyうるし mentioned in an interview that he had been wanting to do the next vocal for some time, but focus was always on expanding the Yukari vocal before then.
Akari was a secret project and nothing was ever shown to the public. Each member of the team worked independently, bringing in voice actors and singers to interview, eventually resulting in 10 candidates. They noted, as the character and voice would grow, this would be a long term relationship between the team and the candidate. Ah Software provided advice, songs were recorded in the voice and tested to see how they sounded. The audition took 3 days to carry out, resulting in a 4 day session. Though they knew what they were after no on-the-spot decisions could be made.
Temporary voicebanks were made, these have been known to occur in the past with other Vocaloid developments and act as tests on how a voice fairs within the Vocaloid software. Both Vocaloid and Voiceroid were sampled at the same time to make a overall judgement of the voice. Since Ah Software had 7 years of experience of Vocaloid and Voiceroid by this point, the process was fairly efficient overall.
From the beginning it had to be made clear Akari was a different vocaloid to Yukari. When provisionary voicebanks was made, demo songs were also produced to help the evolution of the development of the Vocaloid along, though ideas had started to form such as titles. When everyone's opinions were gathered, a overall decision was made on things. As with Yukari before her, Akari's voice was made before they even considered the character itself.
The illustrator wasked if they could do the same as they had done with Yukari for Akari's artwork. Listening to the voice of the character, and seeing the characters side by side, the name was picked out about this time. Since Yukari was based on the moon, they kept the astrological thing discussing on if Akari should be based on the sun or stars. The name had to hold a story behind it. "紲" meaning "Bond" was problematic for them because it could be mistranslated to "tying people" and they also considered forcing the word "Star" into the name itself. Eventually they decided on on a name.
Development of the Voiceroid and Vocaloid took place during this, with the Voiceroid recording session taking 2 days and being done in a method that resembled the provisionary voicebank for Vocaloid. Vocaloid, though already one step ahead the Voiceroid, took a further 6 days to record, this is why the Voiceroid was released ahead of the Vocaloid voice. Another day was taken to record exVoice samples for both. It was originally intended for the two to be released on the same day, but the Vocaloid was taken far longer to produce, being 4 months behind her scheduled release of her Voiceroid. Speaking on the exVoice, the issue with Vocaloid is that consonants feel weak at times or cannot produce alternative consonants. The exVoice for her Vocaloid release is intended therefore to be able to be copied and pasted on the sound track in place of Vocaloid alternatives.
On November 30, 2017, Vocalomakets and AH-Software Co. Ltd. revealed a new character to be added to the VOICEROID2 line: Kizuna Akari. Her VOICEROID2 product was set to be released on December 22 that year. It was also mentioned that they were working diligently on her VOCALOID version at the time. Juu Ayakura was confirmed to be the illustrator for Akari, but her voice provider was not to be revealed until the VOCALOID package was released. Vocalomakets later tweeted that there is no information about Akari's relation to her predecessor, Yuzuki Yukari, and only confirmed parts of her biography.
On December 17, Vocalomakets hosted a livestream featuring new Yuzuki Yukari merchandise and three Akari VOCALOID demos. It was revealed that Akari also has exVOICE files and that she was expected to release in 2018.
On March 29, 2018, Akari's preorder period was launched. It was revealed that Akari would be available as an individual pack (physical and digital copies), a starter pack, and a dual pack with Yukari. Her release date was confirmed to be April 26, 2018.
On April 13, Akari's trial was made available.

| Akari is intended to sound kind and gentle with the intention to portray a cute, bright female voice and under the theme of "starlight".
Her package also comes with an "exVoice" set. There is a voice release for VOICEROID2.
|Vocal traits as noted:|
This vocal will register for XSY, however this is a single release voicebank and there are no additional vocals included for her to utilize this function. Therefore users will have to purchase addition voicebanks not belonging to Akari at all for use of XSY from her XSY group "AHS".
