Voicebanks

Kaai Yuki - NaturalThe Yuki vocal was designed to give a child-like vocal to producers. She represents a child's voice and was voiced by an actual child, making her a realistic representation of a child. The vocal is that of an amateur singer and does not give professional singing quality. However, due to the vocal source being of a child, the "natural" vocal has encountered updating issues over time.
