"Kimi no Uwasa" is an original Japanese VOCALOID song featuring KAITO. It was produced and published three years prior to the original VOCALOID release, and was used as a demo to showcase the prototype voicebank's progress. However, the original video has since been removed, with no credits or information given for or about the original creator of the song. Aside from the limited information, it is one of the very first demos created for the Japanese voicebank, prior to its release.
