OnS Theories (24S). Fourth Theory - The end or a plot twist? (Special Theory & Long Theory)
Hello everyone, this theory is quite special since it’s been heard about how the story is getting more interesting and of course, this was actually pointed by @everlastingspiral about some interesting lines one of the interesting character better known as Rigr Stafford stated, therefore, let’s begin!
P.S: Theories are held within a neutral view and ships are excluded!
In the latest chapter, there was certain line that Rigr stated. For some it could mean as breaking the 4th wall:

BUT, is this really the end of the story?
There’s a big NO.
What do I mean?
Despite how odd the situation might be, and the several questions that exist within the fandom which are something an anon asked, my friend Coffee_ross from twitter asked as well, they have answers along the doubts that still exist as @everlastingspiral mentioned in one of their posts.

Therefore, in order to give full detail and proof to this, let’s answer the first question:
1. Will Shikama Doji die next chapter?
The answer to this is a big NO. But why? Aren’t Mika and Yuu strong enough now to defeat him?

There’s a big issue within the whole chapter, but which might the issue be?
Despite the new found strength between Yuu and Mika, they’re still within a demon’s space or the heart of a human where generally speaking, is the place where demon and wielder talk, but, is there proof to this?
In fact there is:

After Mika sent his consciousness with Yuu, all the space or the memory segment he was reviewing from Yuu’s past disappeared, but why?
This is due to the fact that since Yuu and Mika were discussing and sealing the new contract between demon and wielder, Shikama considered it was his victory, all the memories that Yuu held down of those who worked with Shikama disappeared and of course, the return or set point was Yuu’s heart again.
Is there a solid proof to this?
In fact, there’s a big one.
If many might recall, whenever a character begins the process to make a contract with a demon; they’re sent to a scene of their hearts; the demon chooses a place that had a strong impact on the person aiming to bring forward a contract which was very visible in chapter 103:

And of course, after this, the battle took place which would eventually lead to Mikaela reaching the very bottom of Yuu’s heart in order to see what was restraining Yuu, or more exactly, what kind of curse fell upon him:

After this memory segment was eventually invaded by the first which was explained in a previous theory:
OnS Theories (24S). Second Theory - Explanation of the Memory Segment and the World of Illusions.
Therefore, returning to the main point, what exactly will happen to Shikama?
It’s highly likely to see Yuu striking him which of course perhaps for many might be sweet since he has tortured pretty much every character for his own personal agenda, BUT, since he is still in such place, within Yuu’s heart, the damage will be something to what happened in previous chapters whenever a character got injured within someone’s heart:
Image taken from Seraph of the End: Vampire Reign - Chapter 74
Even so, there are two scenarios that could happen:
First Scenario - He returns to Shinoa’s body
Despite how the events turned for the First Progenitor, he is aware he doesn’t have enough power thanks to the very fact that Shinoa literally used poison on herself in order to reach Shikama Doji despite him “abandoning” her, which it’s clear now that even if he left her, the contract is still on hold between them.
Therefore, it’s likely to see him getting defeated and eventually sending his consciousness to Shinoa’s body to be sealed again since the real way to truthfully defeat him would be literally killing him in the real world or outside Shinoa’s heart which is the physical world.
Second Scenario - Absolute defeat
Within this scenario despite how its chances of happening may be sightly lower in contrast to the first scenario; due to the fact that the demon Mikaela is not a common black demon, perhaps his powers might be enough to do enough harm towards Shikama to the point of oliberating him.
(I honestly have my doubts but anything could happen)
But now, within this, there’s another question, which could it be?
2. What are Yoichi and Kimizuki’s condition?
This was something related to a question a dear anon sent me this morning, and of course, within the thoughts of a reader @salamanbrrr, Yoichi and Kimizuki also headed off to Yuu’s heart while getting control over their demons thanks to the drug Mahiru gave them (damn this girl started a business...jk):

Of course, after this, they managed to meet Shikama face to face and briefly fight against him which of course, the fight didn’t last that much due to the overwhelming difference of power giving the results of total defeat of these two:

But, despite how the situation looked for them, I can state firmly they’ll be fine since they pretty much entered within Yuu’s heart while getting control of their demons hearts. Such events have been visible even with their own demons before in chapter 102 and even with Yuu in chapter 104 after Mikaela cut his head:

Now, this might seem the end...BUT in fact, there’s a huge deal going around if Yuu and Mika manage to harm the First Progenitor, what do I mean?
CORRECT. RIGR STAFFORD
3. The end of a limited truce between Progenitors and Humans
We, as readers, have awareness that Rigr and the Progenitors are allied together with the humans in order to take down the First Progenitor, but, it’s precisely here on where there’s a huge difference of goals, what do I mean?
Guren’s side view
Guren, despite being the anti-hero, his main goal is to defeat the First Progenitor since he is very aware he has manipulated everything so the world could be turned upside down, he is aware thanks to Rigr that the First Progenitor has played the role of a fake God and has planned along with Mahiru on how to take him by making alliances with characters that have their respective agendas.
In Guren’s case, it’s pretty clear that defeating the First and resurrecting humanity are his main goals. But, how does Rigr differentiate from him?
Rigr’s side view
In contrast to Guren’s ambition or goal, there’s something that must be defined, what could it be?
Correct. Rigr never stated he wanted to kill the First Progenitor:
Image taken from Seraph of the End: Vampire Reign - Chapter 107
Rigr stated it was the day they’d surpass him thanks to the help he received from Urd, since he alone wouldn’t have been able to take the First Progenitor along having Guren playing part of the plan within the whole ordeal to take the First down, but, is there a single proof on Rigr’s agenda?
In fact, there’s a big proof to this:
Image taken from Seraph of the End: Vampire Reign - Chapter 79
Back when Shikama was possessing Shinoa, Rigr started to set his plans into motions, of course such plans included on capturing Yuu and sending him to Ikebukuro, BUT, within this, he also had planned to capture the First Progenitor, which was eventually visible due to the next picture:
Image taken from Seraph of the End: Vampire Reign - Chapter 81
Rigr’s objective wasn’t killing the First, very asides from the daddy issues at hand; his main goal was to restrain and capture him, leading to an unanswered question which is “Why”.
Rigr is still a mystery in terms of his objectives; he decided to create the Hyakuya sect in order to have power to face him; he aimed to weaken the Hiragi family which was Shikama’s strength for his personal use; he even made sure the JIDA wasn’t left with power so he could restrain Kureto and Shinya’s demon to eventually face the First with everything set into motion, but now that the First is on the very point of losing, another point to this list adds up:
4. Shinoa’s fate
It’s known that Shinoa was pretty much Shikama’s vessel for quite a long time ever since he decided she’d be the perfect vessel he needed to possess; but, what he never expected was that she would eventually fight for her own life, her own desires, and decisions along her fate; but, after some events, Shikama decided to leave her since she was getting on his way, which of course, it only worked briefly since she managed to weaken him again by using poison, to which surprise of many, managed to weaken Shikama:
Image taken from Seraph of the End: Vampire Reign - Chapter 107
But, within this, there is something that must be considered. What could it be?
Shinoa’s current state is literally one of a human without a cursed gear protecting her body, since Mahiru warned her that she was using poison in order to destroy the cells of the First, and of course, the evident reaction of this poison was displayed on her eye:
Image taken from Seraph of the End: Vampire Reign - Chapter 107
To add more to this, there are two scenarios happening here:
First Scenario - Shinoa’s close death
Within this scenario, there are two other scenarios to be considered, and that of course, is very related to the First Progenitor, what do I mean?
It’s very clear that chapter 108 will lead a battle between Yuu and the First, and the outcome of it might be favorable towards humanity, BUT, there are few problems:
1. How badly will be the damages suffered if Shikama returns to Shinoa’s heart after receiving the damage of a not common black cursed gear such as Mikaela?
It’s known that the demon Mikaela isn’t the average demon in contrast to Asuramaru, which is due to the fact that the demon Mikaela holds even more power stored within him due to how he became a demon in contrast to the Apostles chosen by Shikama.
Which only leads to wonder these questions related to the damage inflicted by Mikaela:
-Will the damage received towards the First will also directly affect the wielder?
-In case Shikama simply returns badly injured to Shinoa, will she be able to withstand the posion within her body since the First won’t be fitted to heal her body in contrast to how other cursed gears work?
2. WIll Shinoa still be safe after a possible victory for everyone that opposed the First?
This second scenario makes a possibility as well due to the fact that, once the fall of the First takes place, will the progenitors keep its truce with the humans or will new goals within them appear?
In case Rigr Stafford follows his original agenda of capturing the First for his own personal reason, it’d mean that he might target Shinoa since he is very aware where exactly the First Progenitor resides, or rather, he is very aware which is his current vessel.
But, in case this scenario happened, would that be possible?
There are several factors to be considered.
1. Yuu won’t be in shape to fight since he’s not sustaining one cursed gear but two; and this is very visible in past chapters.
Back when he fought Ky Luc after unleashing his seraph powers, he was left in a pretty bad shape leaving him unconscious due to the massive power he spent. And the very fact the demon Mikaela requires desires to fight with Yuu, it’s possible that Yuu’s strength might be deplenished specially considering that he wouldn’t face one progenitor but three.
2. Guren might be not be capable to fight.
Within this, it’s needed to remember that Noya is literally K.O after Mahiru stabbed him with a drug; along the fact that Mahiru is literally materialized in the real world drugging herself with poison in order to halt the First Progenitor; thus leaving him quite powerless.
3. Yoichi, Kimizuki and Mitsuba by themselves won’t be able to face down 4 vampire progenitors of high rank.
The very fact that even if two wield black demon series, doesn’t mean they’ll be able to fight against 2 second progenitors, one 3rd progenitor and one 5th progenitor.
Krul alone isn’t a match either to Urd or Rigr due to the massive difference of age and speed both hold.
5. Mitsuba’s character development
One thing missing as well is Mitsuba’s character as a whole; we have no information of her demon nor her role in the story to whcih, the current point, has been pretty much so small.
6. Shikama’s past
Despite seeing Shikama in despair, we still have no information of his past, how he appeared on Earth, how he managed to be the way he is, and how he was able to manipulate everything around him.
Therefore, this only highlights that ONS is far from over; there are several factors to cover within the story, and it’s very likely that the current arc we have read so far, will come to an end only to bring forward a new one specially since it was hinted by certain character that they would eventually need to fight millenia monsters.
What do you think dear readers?
Let me know!
