What a chapter, so many things make sense now, and I think I even understand how blood techniques now after the explanation some chapter ago and how the count used his blood in this one.
I don't know how to word it right, but I think I can "see" how it works now, a little of its inner workings, it is like... the blood is just a medium, a catalyst where the power resides, for "human" users they can only use a single "element" in the blood and I think they mostly are limited to properties that are still connected to the "physical", with the exception of Klaus that is manipulating time (and Jyubei that is practically a monster), but BBs can twist the laws of nature with theirs.
There are still many things about that ability that need understanding, such as how the "elemental" inclusion is made, and who or what created some of the style in existence.
And with this chapter... if is official that the one-shot so many years ago is entirely canon, there are stages of transformation that need repeated bites, and Klaus is a half Blood Breed in the penultimate stage of transformation still.
As always Morzo Guazza team... there is few words that can describe how grateful I am for this fine confectionary.
