User blog comment:AquilaeAltair/Ons Theories. First Theory (S3) - The black matter, something that adquired a physical form/@comment-36009152-20190607002141

''Answer for the first part of the theory, the shadowy substance seen in Chapter 79! Best read downwards, this one first with the below reply read second.''

Hard to say what was more menacing, past seraph Yu in the sky and everything involved with that, to seeing that even back then Sika Madu possessed wings and then performed that action.

The fascinating thing is for all the rampaging blood lust seraphs are renowned for, they are capable of honing their inner murder all humans instincts. Sika Madu confirmed it with issuing guidance to Yu, and yet makes me think that Sika Madu was not born a seraph (who would train him to control his impulses?) rather he acquired them, none other from Yu who may be the original seraph in all possibility.

Yet onto the greatest mystery from Chapter 79, none other than this spectral black substance. Here it is and lots of it floating around in what is presumably a fluid of some kind what with the bubbles and containers it is in. Yet as we can see this… thing whatever it even is XD is perfectly at home floating in the air and that is definitely meant to be an eye. It has tendrils and to amplify the creepy up even more that is in all likeliness not an unassuming mist to be used by Sika Madu, the black matter is a living entity, with it’s own will as well! Just looking at it right there is spooky to the maximum, and just infiltrating Yu who looks dazed and out of it is dreadful as well.

It is confusing on how it was interacting with Yu in the frame there. Yu’s neck is completely healed, having consciousness as well since his eyes were closed before. Yu is calm to the point of inactivity so that black matter was not doing either of those things, not healing his body or supressing emotions. That is unless it was healing internal injuries (unlikely since seraph Yu can heal of his own accord) or is supressing the inner seraphs emotional state so that it does not flip out again – which is likely the black matter entered Yu’s head as soon as Ashera came into the room so that is possible.

I wonder if the black matter is instead a fledging/beginning stage of a demon. Asuramaru and other demons can take a non-corporeal black fog form, with eyes as well. We may be witnessing the first demons that could be formed and kept in the containers in the room Sika Madu was in. They could be invisible to others but Ashera could perceive them on account of being a very powerful complete vampire now presumably having drank either Yu’s blood or Sika Madu’s himself. No matter what though the black matter there is creepier than any other demon, somehow XD

With Sika Madu’s incredibly horrible experiments, do you A) think it meant he has been experimenting with Yu for 600 years, or B) has performed different experiments to create something like Yu with Sika Madu using his own pre-existing powers (which would explain Yu’s young appearance, he hasn’t been a child for 600 years maybe) of which Sika Madu succeeded when Ashera was dubbed a success, to join Urd Geales and Rigr Stafford. For possible option A) that those three are vampires not seraphs makes me think Sika Madu and Yu have been around 600 years and are finally creating vampires successfully. B) That Sika Madu is willing to share his power around makes me think Yu, Urd, Rigr, Ashera are just creations he is making, he has made a seraph, now time to make vampires and see what he can get, so Sika Madu is the source of this rather than Yu.

Returning to the black matter, that is a possible explanation of Yu’s memory loss. Before could have just put past Yu’s lack of memories, his mannerisms and way of thinking to have been simply been down to that he was a seraph and that is how they acted and thought! Still it’s a good observation that the fog is behind it, and that this black matter is a guarantor of containing seraphs. Makes me think who else but Shikama Doji who would pass along the knowledge to the Hiragi family, they would refine it into weapons to not pacify a seraph but able to outright control it as they did with Mirai around the present day.

That is fascinating the point about this demon/black matter whatever we may think it is, that it could be an energy source and that Sika Madu could create it. It has to come from somewhere but whether it’s a magic of sorts older than seraphs, demons and vampires (if it can affect seraphs it is something else entirely) or a Sika Madu creation formed in a dark ages lab like setting is something that must be known! On one hand it could very well be something created by god, what is higher than a seraph that could subdue them? On the other, humans or whatever Sika Madu has turned himself into at this point may have broken the taboo as its forbidden for him to use it himself.
