Okay, okay...
Just now I've been looking at
Arcueid Brunestud's profiles based on her abilities and powers, and she's (at least resistance-wise) interesting to say the least. I'll quote them below:
"
Resistance to
Magic (Can casually shrug off virtually any form of modern magecraft and easily pried through
Sion's Bounded Fields),
Conceptual Weapons (She has developed a resistance to most Conceptual Weapons and believes herself to be vulnerable only those that she has not experienced before,
was only knocked over by a point-blank attack from the Black Barrel Replica, one of the Church's most powerful Conceptual Weapons, and
got up unharmed),
Existence Erasure and
Reality Warping, among many others (The Moon Cell couldn't delete her in
Fate/Extra because her Authority eclipsed its own),
Immunity to
Death Manipulation (When under the full moon or when at full power, Arcueid does not possess a concept of death unless it is forcefully placed upon her by a being of great power, making her immune to abilities such as even the
Mystic Eyes of Death Perception)"
And abilities wise she's similar to Ragna.
Now according to this she is able to resist modern magecraft which is a class of magic that BlazBlue technically belongs in, although magic in BB works differently than in Masadaverse and also what does the profile mean by "modern magecraft"? 21st century magecraft? BB takes place in the 22nd century.
Although there is also her resistance to Conceptual Weapons which is basically what the Azure Grimoire is since it is a part of the Black Beast. Although it says that she is only vunerable to weapons she hasn't experienced previously, if that's true then she may be in trouble. I don't there there any weapons in the Nasuverse that are similar to the Azure Grimoire, which is simply hax the weapon, unless Gilgamesh has an Azure Grimoire himself.
Her other resistances don't really help here, death manipulation and existance erasure are not equal to soul hax.
I'm not saying that she could be able to fight the Blazblue-verse, I'm just giving the facts and evaluating them. Although if there is one thing that Arcueid can't resist, it would Rachel's slave Red.
