User blog comment:Thesupremejoyner98/Grimm that can cut through aura/@comment-6830001-20150115062222

It seems the Grimm can already cut aura somehow so it doesn't have to be a new species, just a super-evolved Grimm and very powerful. It could also make us see them frightened and wondering if they are determined enough to be a Huntress and realize what is their goal (following whar we saw in volume 2).
