歌愛ユキ (Kaai Yuki)

Kaai Yuki is a Vocaloid developed by AH Software. She is the only Vocaloid to date whose voice provider was a child at the time of recording, and as such she’s remained anonymous.

Her voice is a young girl’s, with a strange quirk. Yuki’s voice provider was coming down with a cold when she was due to record, so her voice has a sniffly, heady quality. The producers apparently liked the sound, so it was kept.

Yuki’s appeal has been somewhat limited in the Vocaloid scene, but she’s caught the hearts of a few producers, and Sohta’s “Ikanaide”, featuring Yuki, garnered universal acclaim.

Pop-rock producer Inabakumori’s first album, ANTICYCLONE, features Kaai Yuki (almost) exclusively.

Due to Yuki’s voice provider growing older and her voice being unrecognizable as a result, when the time came to update her to Vocaloid V4, a different provider was hired.

Kaai Yuki is described as being “as tall as 10 large apples.”
