Does anyone know how i can talk to Kanon, On/Off, and Vocaloid i need to talk to them about staring and singing in my anime?

yes i have her nomber it is 09846132759

Here is the thing; I doubt that they will sing of ster in your anime...

Why don't u just go to Kanon's website.But her website is in Japanese. And I've tried to talk to the Vocloids.

I know this is not what u want to hear but it's very least likely to talk to her and tell her to sing for a fanmade anime and it's also VERY least likely to talk to "vocaloids".
Vocaloids are vocal synthesizers...not people.
