Previously to his announcement for DeepVocal, Aoki Kazuki was an UTAU.
On June 16th, 2019, a cover was posted of Kazuki singing "幻想ピアニスト" (Gensō Pianisuto | Fantasy Pianist) by ひとしずく×やま△ (Hitoshizuku × Yama△). On the same date, a Twitter tweet confirmed Kazuki would be released "soon."
Though a given name, with a literal English translation, the Japanese characters "青木一樹" mean,
青 (Ao) - Green
木 (Ki) - Wood
一 (Ichi, but when combined with 樹 (Ki), are read as "Kazuki") - One
樹 (Ki) - Tree
His DeepVocal design has only been shown as a silhouette, however a previous UTAU design shows him as having pale skin and tan/light orange hair. He wears thick glasses with thin rims, ash-grey eyes, a military-style green jacket with white, black, and orange accents, and short white gloves.
