Yukimoyoi, Nagoriyuki's new special move looks a bit strange. His mask is darkened but it has a blue-red aura mist streak coming from it and his Blood Rage meter is not increasing in that state. You have any possible ideas on what Nagoriyuki is actually doing here? It looks like a move that he must've learned to manage his Blood Rage.
In the initial startup of the move, he plants his blade in to the ground, almost like setting up a temporary domain space.
As we have seen previously, Nagoriyuki’s Gashadokuro blade “bleeds red” when his Blood Rage is fully active.
Since we already know the blade can transform to varying lengths, it’s also possible that the “blood” unleashed by the sword is a kind of cursed blood, or perhaps a binding ritual that synchronizes with Nagoriyuki’s “vampiric blood”, making him one with the sword in a kind of symbiotic relationship.
A “wave” of blood gushes out from the sword across the ground, which is likely the means that Nagoriyuki establishes this domain space.
In other words, it is very possible that any living beings in contact with the sword’s blood can feed Nagoriyuki with a certain amount of life force, even if it’s temporary.
What happens next depends on Nagoriyuki’s actions, as the mechanics of the skill have established. But it is in this way that Nagoriyuki can either “draw enough life essence” to either enhance his blade for a time, or to curb the current amount of blood lust he and his sword crave.
And while this is still a working theory and speculation, it is not without evidence from other sources of Vampire Lore:
Most Vampires establish a domain within their castles, usually with a blood contract that binds the castle to its master. In exchange, the castle itself is given blood to feed on to continue and affirm the contract it has with the Vampires. (And this is also very similar to how a Master Ghost is an extension of a Master’s Soul in GG2 Overture terminology, since the Master Ghost and Servants are an extension of their summoner’s very soul.)
In addition, this blood effectively creates a space of influence throughout the Castle that a Vampire is given complete control over: whether it’s being able to sense intruders, change the castle’s form or shape like a maze or labyrinth, or even manifest creatures and minions from the castle to serve the Vampire Lord.
To a large degree, anything the Vampire’s blood makes contact with falls under their influence, or at the very least becomes “cursed”.
Vampire Curses don’t necessarily put a detriment on the Vampire themselves, but act more as a Boon or Buff to the Vampire when they are inside their own turf or space of influence.
You could also say that this blood also determines what is or is not “one” with the Vampire. As a Vampire’s blood is the source and reason why Ghouls, Revenants, and Thralls are created as slaves to a Vampire, if not becoming lesser Vampires themselves.
Of course, it is very possible the Katana’s blood is very different and functions differently too.
One of the major secrets behind Castle Dracula in Castlevania lore itself is that the entire architecture of the castle was established from the power of Chaos, and is comprised of both living and undead flesh as well as blood at its very core. In fact the boss known as “Legion” serves as a massive “sphere” of bodies and undead corpses and is in fact the Castle’s true “body”.
Back on topic, when a Vampire establishes a domain space, they can use that space to “feed” on anything within that space, sometimes without even touching whatever was the victim!
The Blue Aura, along with the massive shadow that covers Nagoriyuki’s appearance, implies that his power has been activated to a larger degree.
In Nagoriyuki’s Arcade story, this very “shadow” can even go berserk of its own will, and Nagoriyuki had to fight it by himself before! Zato=ONE even helps him defeat this Shadow, which is basically a larger fragment of his darkened soul made manifest, and also an embodiment of his lust for blood.
Slayer’s shadow is very Red, but also very Black as well!
Yukimoyoi translates to “Impending Snow” or “Threatening to Snow”, but in terms of the metaphor, Snowfall casts a paling over the landscape: White Skies, Grey Atmosphere, similar to a sudden change in climate when it is about to snow.
So in summary, Nagoriyuki strengthens his blade by expanding its blood influence, and this in turn lessens his blood cravings!
As a side note, this very same technique was used by Nightmare in Soul Calibur IV to turn Ostrheinsburg Castle in to a large vessel for Soul Edge to feed upon Souls with!
