I've also recently learned that despite the avatar being public, it doesn't show up in avatar search worlds. So for now, here's a direct link to clone the MMZ Zero avatar in VRC! (As the description says, and as you may have noticed, it will get updated a lot for a little bit)

And lastly, here's a link to the Ciel avatar,

(Disclaimer : I've been told by a lot of people that the camera transmission system causes motion sickness, so please be careful when using it as it takes your entire field of view and doesn't show depth the same way you normally would see it)

Here's also a link for the Copy X avatar (Doesn't receive nearly as frequent updates, as Zero is already being used to test a few systems that Copy X will use later)
