To tell the truth
This tracking is sssssuper awful, garbage. 4500 yen for such a garbage is a waste of money. I guess FT from this author is the worst versions among others. The only advantage which i can see is that ears reacts at emotions from FT, thats all.
There is a much better verson in VRC however i dot know what is this(its public and you can find it and tast for comparison i guess):
