So okay, after a loooot of work... My Poor Krimzon Guard is not gonna work for now in VRChat.

I think I will take a break but I learned quite a bit about rigging and how to get models to work that were not PMX files. 

I think my next attempt will see results and hopefully I can share it with you guys.

Here were the things I struggled with the most:
-Basically I didn't join all the meshes together and make the model a single object off the bat, which lead to me making the entire rig before having a single object. This I think caused the model to have the "Failed to find a solution for one or more bones" Error which I battled for a while.

The above problem then lead to another. I automatically weighted the bones regardless of the lack of joining to see if I could just force it to work. it did! However this lead to a shitload of clipping errors that I barely fixed with Weight Painting.

Then in Unity it didn't read most of the bones because I did not name them correctly.

So I fell flat on my face pretty hard but not after making a pretty damn good show of it. 

I think now however I am going to take a look at some proper MMD animu girls and see if I can port them in without any issue.

Someone mentioned earlier they had a list of what to name the limbs? I'd love to have it. Also I wanted to add fingers but I didn't see that option when I went to the configure menu in Unity, how are the fingers done for the full body tracking?
