Because if you do, you're gonna have some copyright issues if you use Hatsune Miku

Seriously, this is like the fourth time someone has stolen MikuMikuDance/MocuMocuDance, music and community made models and animations and tried to sell it. MocuMocuDance is FREE. Just download it from the developer's webpage, find some animations and models to go with it and you're good to go. http://www.vrai.jp/vr_mocu.html https://youtu.be/UYwFiYnALmc...
