Mist

Hun!

Suddenly, the expression of the Raxth changed as it stopped attacking me mid-way.

A faint mist has appeared on the battlefield all of a sudden, and it is getting denser and denser. 

I could see the mist and Grimm clearly, but I am sure it is having a problem doing the same.

"Empire of Mist!" It said as its expression became serious and dense, soul sense had spread from it, not only from it but from every Grimms as the mist began to denser by the second.

I couldn't help but get shocked seeing the mist or, rather, its immense power, far more than I had imagined.

Joana had told me about the progress of my mother, and she herself was proof; she is a Grandmaster, but with the power of her art, she was able to fight the Grand Lords and had even killed one.
