Hoshikuzu Yuzuko (星屑ゆずこ(ほしくずゆずこ)) is a voicebank for the UTAU and UTAU-Synth program.


Yuzuko Hoshikuzu was a character conceived back in 2010, but was released as an UTAU voicebank on April 5, 2017 with a VCV compatible voicebank released the summer of 2017, under the name of Yuzuko Hoshine. Her 2 Appends titled "Calm" and "Excel" were released on her 1st anniversary, April 5, 2018. On January 1st, 2019, Mei-Saime made a post on the official Twitter of Azure Fragment about name changes to the group and Yuzuko's surname, which became Hoshikuzu instead of Hoshine. She is set to have a beta VCV voicebank to be an improvement of her previous incarnations along with beta Chinese and English voicebanks. Her new revised design was revealed on March 1st, 2019.


Yuzuko is a 17-year-old high school student and a mage who specializes in magic, and also psychokinetic abilities. Due to her "older-sister" type personality and the fact of her lineage heritage, she is given the codename: "Eternal Goddess". Her theme color is #FCAA95. Originally, her design had brown hair and blue eyes in an array of costumes in the lolita category from a maid styled uniform (2017) to a frilly type purple dress (2018). As she goes into her new design, Mei wanted to portray a gentle, sister-like character, but brimming with beauty and an easy approach for newcomers to familiarize.
