Kaai Yuki
Kaai Yuki is a Japanese VOCALOID made by AH-Software Co. Ltd. and released in December 2009 for VOCALOID2. What makes her stand out is that she's the first female VOCALOID whose voice comes from an actual child—an elementary school student. Her voice provider has never been publicly identified for legal and privacy reasons.
She's best known for her distinctive childlike vocals, which opened up a lot of creative possibilities for producers who wanted to work with a genuinely young-sounding voice. Over the years, fans have associated her with alternate personas tied to specific song series: Yukina Freesis from the Aku no Musume (Evil Daughter) series, and Yuki Kaina from the Venomania-kou no Kyouki storyline.
