This way too INSANE. Those smear are so sharpe, you mix it to hand to hand. It add a lot to the fight. For example at 0:19 - 0:22, the smear so good ...
An d the whole section at the end from 0:48 to end make me speechless. WOW

I really want to know the person that animated this ... Such a insane animator.

This scene is from "Fox Spirit Matchmaker", and made by an animation studio in Taiwan called R.Animation.

There is some cool stuff on the company's twitter :D
