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

yes i have her nomber it is 09846132759

Here is the thing; I doubt that they will sing or estrela in your anime...

Why don't you 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 you want to hear but it's very least likely to talk to her and tell her to sing for a fanmade animê and it's also VERY least likely to talk to "vocaloids".
vocaloids are vocal synthesizers...not people.
