Despite the pain, it amazed Muku how all the elements had unique ways of hurting him.
You'd think pain is pain no matter what, right? Well, it turned out to be untrue. Muku had experienced so much pain that he could tell that it was different even if it had the same intensity and seemed the same on surface view.
He didn't know how he felt about being so sensitive to pain. It made him feel dirty in some way. Like he was a seasoned masochist or something. Fortunately, he didn't enjoy the pain. So there was still hope for him.
Anyway, Beast Aura like the elements before it, hurt him in its own way. I wasn't intense like fire, methodical like ice or violent like lightning. If he had to describe it, he would say that it was vicious and wild.
It invaded his body and went wild, ripping up his insides left and right. And of course it hurt like hell. The way it behaved, was almost like it was venting all of the grievances Jade had toward Muku.
