Huan Xiao Yi (幻晓伊) is a vocalist for the Sharpkey engine, and the first vocal released.
On July 21, 2016, a debut video for the Sharpkey engine and Huan Xiao Yi was released as well as the first public download of both. 
In an interview with Vocaloid News Network, on August 25th, it was confirmed that both Huan Xiao Yi and Sharpkey were solely developed by Boxstar. It was also confirmed that Boxstar had no plans to create an English translation of the software's GUI, though if he said if romanized pinyin was ever supported he would consider it.
In the same interview both the name interpretation and introduction as well as some development information were revealed. Her temporary name during development was 「晴音」 "Clear Sound".
Her voice provider has not been revealed, though it has been confirmed she is not involved in the VOCALOID or UTAU communities at all. 
She is described by Boxstar as "..the singer who leads you to the fantasy world of music."
幻=Fantasy, 晓=Dawn, 伊=Beauty
AppearanceEditHuan Xiao Yi is drawn by the same illustrator as VOCALOID3 YANHE, which might have influenced the finalized design. Concept art shows that Xiao Yi is based off of a piano mixed with a magical singer; She has long pink hair that fades into a darker, more saturated hair, and pink is prominent in her color scheme. Her black skirt has a piano pattern and is pink on the inside of the fabric. She wears matching black stockings with light pink boot heels and a bow on her top. Small accessories such as a wrist-let and golden hair tie are included as well.
