This comment is for the similarly noted characteristics between past Yu and present day Shinoa!

Sika Madu’s calm ‘this is hell’ speaks volumes. That does not suggest to me a seraph focusing on divine punishment, rather a man who has acquired seraph powers making an astute observation of the environment. Yes it is a hell that Sika Madu is creating, but highlights a key point nonetheless on how he see’s himself. As to why he admits, or maybe just speaks matter of fact that it’s hell and he is the ruler having used children as guinea pigs to… (to what exactly, see if any can survive Yu and live to be a vampire? No, it was not a test to see who could drink Yu’s blood and survive to be a vampire, at least with Ashera it was a test to see if Yu could contain his seraph urges, the test failed but Sika Madu got a different test result, he gained another vampire and with Urd and Rigr he was looking to make some more).

Anyway, Sika Madu professing it is hell, whilst it is for the children involved, would he mean it is hell because of the black matter and how it can placate a seraph utterly. It may be an insight into Sika Madu’s mind, that he considers it hell that a seraph can be reduced to, well a child maybe because the same can happen to him… just a thought that can be read in various ways.

Would wager on you being right, Sika Madu wants to create vampires here but as of yet has never said why, as Ferid asked when he met him in Shinoa’s body. Sika Madu does not just want to have a pet seraph in Yu, neither satisfied with just controlling him, he has already mastered that with his black matter which could be a long term inhibiter of seraph powers thinking about it. With using Yu it all points to creating more vampires, though ones with only Yu’s or his blood (he doesn’t have Urd and Rigr go around biting things to our knowledge to spread vampirism that way) for as of yet unknown purposes. Overall Sika Madu does not seem to want superior beings in vampires, he largely forgets his creations when he begins hopping between humans of all beings until he can locate a time Shinoa was born. Maybe the desire to control them was yet another test, to see what he could make and how they could be used for long term goals.

Just on what exactly Sika Madu is, it makes a big difference if he is originally a seraph that has trained or been trained to contain it’s urges. Or perhaps he was a regular man who merely gained the awesome powers of a seraph. At least the latter could out rule him being the Michaela angel. This could also mean much of Sika Madu’s plans are to prepare for ousting a stronger being than him, likely the real Michaela. The interesting thing as well is he at least considered giving his blood to Ashera, before weighing the risks but he is willing to take them which is telling.

Would like to know the extent of Sika Madu’s deal with the Hiragi family. Whereas before he could have just been content to use them as hosts to jump to each family head, this theory and the black matter raise some further possibilities. Mentioned above that he could have relied on the Hiragi families technical prowess to refine the black matter into a seraph manipulator. Yet as well as that maybe he also made a deal for them to turn him from a seraph vampire if he is truly both of them, but make him into the third one, a demon as well.

Black demon like mist, have the Hiragi family fuse it with Sika Madu to give him the third aspect of these beings. With him being part demon that erases the risk of people getting suspicious of an immortal being within their very presence as Shikama Doji can now move between the generations as the demonic ghost he would be. That gives this black matter it’s form, as Sika Madu himself and also the foundation of the demons who would come to the point where they rival the vampires in the present day. Cursed gear would allow their powers to be contained so humans could use them against the vampires, courtesy of Mahiru Hiragi as well but it all began with Sika Madu.

That’s one idea, vessel Yu is another one, again it may be a foundation of sorts providing someone with seraph powers that could be tapped into. Guren was certainly banking on that for his own plans to undermine the Hiragi family as a result of his experiences.

With Sika Madu maybe having made use of the black mist to pass himself down through the ages, so could the same be done with Ashera who would, by chance? Come into contact with another created experimental prize in Mahiru. Did Sika Madu want to create Mahiru and Shinoa and then arm them with already strong beings of Asuramaru and himself? If so why? Only hunch is something stronger than himself made the black matter, Sika Madu broke a taboo to manipulate it but is also hoping the experiments will pay off when the fruits of his labour produce the humans and weapons he had in mind to presumably fight and defeat whatever created it.

It is hard to think whether Yu has dulled eyes because he’s a seraph. Oh yes by the way Yu isn’t dumb, he's very clever he figured out how Ashera knew his name because he heard Siga Madu say it! Yu is truly the cutest for real! Also hard to say whether he was just a young kid content to play all day and think nothing was amiss.

Still whatever the case yes past Yu is eerily similar to how Shinoa was when she was young. As for the black matter taking a human form that is compelling, can definitely believe Sika Madu could forge what must be a signature magic to control divine life and then create other forms of life itself. If that black matter is the basis for the advent of demons look no further than someone who could contain a demon like Shikama Doji, by default of being an actual flesh based demon, Shinoa! The control mechanisms would be set as well, witnessed first hand in keeping Yu passively quiet. Then extended as the strains of black matter grew more potent over time to the present day where they could be a human and one subject to complete control. No need for it to hover overhead and enter through the head, it’s already there within, rather darkly!

Was thinking that is a way Sika Madu could get even more powerful, if sky is the limit as a vampire, seraph and demon where to next? Easy: grow a vassal through the ages to fuse with further down the line. With the timing he would also be flanked by another Hiragi descendant, Mahiru alongside her cursed gear, Asuramaru, with a fusion of power all present in the right time period for whatever Shikama Doji is preparing for. Oh yes, Shikama Doji is at least wary of the Hyakuya Sect and Rigr behind it having moved to do something about their interference. With Rigr being aware of Michaela and a sun god both of those two are possible foes that Sika Madu would prepare this black energy for in order to have a shot at countering? Could be!

As for Shinoa, having black matter exist as a human would possibly allow many to exist at least in the mind if that is what he meant that without Shinoa demons could not exist.

You know that may be further evidence Shinoa is a black matter engineered being. Consider that Mahiru was correct that ripping demons from the heart is the only way to be rid of them. She could have done this and Shinoa could have survived the procedure being an emotionless demon based entity.

The final part of your theory gives it ever more weight! Whether it was the Shikama Doji part of Shinoa that quelled the seraph as explained in another [https://owarinoseraph.fandom.com/wiki/User_blog:AquilaeAltair/OnS_Theories._Eighth_Theory_-_Shikama_and_Shinoa._Two_sides_of_the_same_coin. theory], this one being commented on is a shade just as likely. A blast from the real ancient past (ha) where the same black matter that tamed the anger in seraph Yu could return, for Shinoa could be constructed of the same substance.

Yes, that is the only thing that can explain it at this point. Sika Madu would be very proud this mist creature, calling it that it looks alive, could have such far reaching effects as it does. Terrible news for Shinoa and everyone involved but as horrible as it is cannot be denied the black matter is one fascinating…. Thing!
