User blog:AquilaeAltair/OnS Theories (S5). Sixth Theory - The method used to extract a demon

'''Welcome to another post of theories. Being honest, writing down theories to the point of reaching the current chapters and finding clues for answers is quite wild and exciting. Honestly, thanks a lot.'''

To begin with this theory; I give credits for giving me the idea to someone whose name is Montell Riles; during a conversation in a post, there was a discussion about chapter 82 and somehow the idea popped out thanks to him for pointing out stuff in the chapter.

Let's begin with this theory, I hope I can cover aspects from past events in the story till the current timeline. Now, there's something that really made a huge impact in the fandom and that was seeing Noya again after fusing with Mahiru after she stabbed herself with Noya in the Light Novels.

So far, we knew that both merged as one; but still Mahiru was determined as something that couldn't be labeled as a demon even if the efects were such as possession, power abilities were present; which somehow it is relatable to Shikama Doji to certain extend. Of course, this doesn't mean they're the same type or same beings.

To explain this better, let's point out some characteristics these two demons share:

Mahiru-no-Yo

Firs of all, Mahiru-no-Yo is the fusion of Mahiru Hiragi and Noya; Guren's previous demon. The one that Mahiru delivered to Guren in order to fight against all the obstacles in the catastrophe timeline.

Traits and characteristics: Shikama Doji
 * Mahiru-no-Yo retains her memories of herself, not of Noya
 * She has the same demon abilities like all cursed gears do
 * Her memories were restored mainly to not lose herself and allow Noya consume her
 * She was working as a vessel to restrain Noya of consuming Guren totally
 * Her mind, goals and ideals are her own, not influenced by Noya
 * She cares about those around but knows the price about going to the dark path or sacrifice path
 * Her memories were rescued mainly thanks to Rigr Stafford

In Shikama's case, he's been well known as the First Progenitor, demon, Seraph or vampire. His traits and characteristics before and after becoming the demon known as Shikama Doji are: Now, after exposing this, there's a huge gap in power differences between Mahiru-no-yo and Shikama Doji; but now, focusing on the theory, how does this relate to separating a demon from its host?
 * Demon abilities like any cursed gear
 * Independence, which means, he can manifest or change his form without a command
 * Infiltrating in other's hearts
 * Authority over seraphs (Only living proof is Mirai so far)
 * His memories are fresh, he retains all of his memories mainly because he wasn't a result of a human becoming a vampire
 * He is a seraph that managed to become a cursed gear
 * Authority to manipulate humans at his will
 * Close powers to God or considered as one
 * Doesn't care about his actions and the results of them if it leads to what he wants
 * He required a vessel to manifest in the real world as the progenitor itself
 * After possessing Shinoa, he can't be labeled as a demon mainly because he hasn't been one; he's been a seraph with total control and authority of his own powers
 * All of the things that exist such as vampires and seraphs are mainly his research and creations

Well, as we saw, the way Mahiru managed to stop Noya from overcoming her or more likely to take over her and Guren was through a strong restrain or seal; that seal doesn't literally mean one will use a talisman and place a seal like type but instead; it was more like keeping Noya inside her heart. Taking into account that Mahiru was a non demon according to Byakkomaru, this implies that Mahiru was in fact what was left of her as a vampire, instead of becoming a demon after being stabbed; it could be said that Noya consumed her blood.

In some animes they say blood is like a coin, yes this is based a lot on Hellsign; therefore, we could say that Mahiru's soul and body along came into contact with Noya, merging them as one being; of course, there was a fight of dominance which is why Rigr interferred in the light novels. There's a picture on which Mahiru is seeing with a dagger on her neck; this could imply that Mahiru was having something like a hard time with Noya to see which one of them could be there.

Still, when Mahiru and Guren were preparing for Noya's entrance, Mahiru and Guren divided the power of Noya in two; which means that a part is residing in Mahiru while the other is residing in Guren; which for a certain amount of time will make Guren the most powerful demon but still; what does this have to do with the main topic?

Well, there's one sole issue that hasn't been explained in the story aside from many doubts that exist within the fandom and that is, how Mahiru managed to extract a demon from someone else's heart?

First of all, thanks to this chapter, there's a possible method on how to do so; let's begin with these points for the theory This method sounds quite weird but well, let's proceed. In the light novels when Mahiru fought Kureto; she had an interesting question directed at Kureto himself; said question was if he was able to remove the demon from his heart; if he was able to take his heart in order to remove the demon.
 * First Method - Heart removal

The question itself is weird, confusing and at the same time, it doesn't carry a huge importance but; with the latest events; was this truly not important? Well, there's one person in the whole OnS universe that had her demon removed; that person was Shinoa Hiragi. The methods are never explained as to how Mahiru did in order to remove it.

If we think about the cursed gears, and the black matter that appeared in chapter 79; it could be infered that demon cursed gears have that sort of material in order to infiltrate in a person's heart; what do I mean?

Well, the demon curse which was developed by Mahiru may have allowed demons to infiltrate users with the same sort of black matter; therefore, whenever something happened to the hosts, they could feel the same pain or at least feel what their hosts do. Which is something we can see when Asuramaru scolded Yu for consuming the drugs; same case when Shikama was stabbed by Kureto, Shinoa ended up feeling the pain in the same place Shikama was stabbed.

Therefore, it could be said that, in order to remove Shinoa's demon from her heart, she might have done a surgery or something similar in order to take it away and absorb it herself.

Therefore, that'd explain the memory loss from Shinoa until she touched Shikama again thanks to Guren's delivery. This method relates a lot to the light novels and the manga story; well, in order to make Mahiru keep her own self after she died or at least after she became part of the cursed gear, Rigr used this dagger in order to make Mahiru stay instead of Noya; which means that Mahiru was not a demon at all, the dagger was focused to retain Noya.
 * Second method - Dagger (Like the ones Rigr owned, same with Ferid)

Then, what does this dagger have to do with the extraction of Shikama Doji from his host?

Well, the daggers are well known to have two effects for now, one of them is to help a demon regain lost memories while the other is to help battle two demons sharing one body; now, what am I trying to say with this?

It is also possible that, in order to divide Shikama from Shinoa either catastrophe timeline and current timeline, they'd need to use mentioned dagger in order to detect Shinoa's mind and soul; of course this would mean that Shikama wouldn't be able to retain the control he has from his current host.

Instead, it'd make him be in a comatose state, allowing humanity to cease his attacks; which would mainly focus on Rigr's main objective; restraining him in order to remove his essence from his host, they have to use these daggers.

This also could relate to the events prior the catastrophe, in order to extract Shikama from Shinoa, she might have used something similar or perhaps she had a dagger in order to attack the human part of Shinoa and make the experiment a success.

The dagger itself would work more likely as a temporal seal; which also would explain as to how Guren is able to have those chains just like Rigr, just like Tenri and Mirai when she attacked and killed the JIDA soldiers as a sacrifice. https://owarinoseraph.fandom.com/wiki/User_blog:AquilaeAltair/OnS_Theories_(S3)._Fourth_Theory_-_Mahiru%E2%80%99s_deal_with_the_First_Progenitor
 * Third method - A deal (A theory that I explained a while ago, but here's the link:

Being honest, it was a huge surprise to see Noya in the latest chapter but, it was shocking to see as well Mahiru screaming in agony; honestly that panel felt like it was ripped from horror movies but still, it was pretty cool. All I can say is that Mahiru is taking part of the demon curse while Guren is holding the other and still, this could also imply how to retain two demons in one body and, at the same time, the key to extracting them.

What do you think?
