Her voice is taken from recordings of an actual elementary school student. However, the name of the one who offered the voice for Yuki is still unknown.
In 2019, for Yuki's 10th anniversary, more details about the voice provider was revealed. At the time, she was only in fourth grade when she voiced Yuki in the summer of 2009. Before recording, she contracted a form of influenza which may have influenced the voicebank's "husky" sound.
AH-Software recently announced that they would be selling their VOCALOIDs in Germany, with Yuki being destined to be the first sold there.
At the end of 2015, it was announced that from March 31, 2016, VOCALOID2 was being retired and no new serial codes were be issued by Yamaha.
AH-Software is planning how to deal with this.

|Package details as noted:|
Yuki and Kiyoteru were designed to be VOCALOIDs that had human-esque traits about them. Yuki is designed to sing childrens songs and has an innocent, soft and cute voice. However, she was not voiced by a professional child singer and does not produce professional singer results. She is still a faithful CV vocal, and gives an accurate portrayal of a child voice.
