OnS Theories (17S). Ninth Theory - Mahiru’s plan
Hello everyone, I hope you had a great day, I hope you managed to spend time with your loved ones, remember to stay safe!
This theory will explain the rather crazy plan of Mahiru’s agenda. While I’m aware she’s the least loved character by the fandom, it cannot be denied her plan finally has striked down or halted Shikama Doji.
Let’s proceed to discuss such plan.

As many might be aware, Mahiru Hiragi has been designing a plan to counter the First Progenitor ever since she got tired of having her life controlled by the Hiragi Family and the First Progenitor; her wings were cut down since she was a genious, one of a kind within the Hiragi Family which only made Tenri hold Shinoa as a hostage, which is something Tenri reveals to Kureto in the LNs of the Catastrophe.

But what exactly has been Mahiru’s plan? What has she been fighting for?
It is finally known that, after she met Guren and was eventually separated from him, she had to endure experiments; but within this, Mahiru’s demanor or attitude turned rather cold until Shinoa was born:

Shinoa became her happiness but at the same time, the one that would pick Tenri in order to cut the wings of a genious. But then, what was her plan all along?
Her first plan or rather original plan was to betray the Hiragi Family by working together with Rigr Stafford, but of course, what she’d never take in consideration was that her fate would be sealed or set in stone ever since she was born. And thus, the plan began; at first it might seem she was the one behind the experiments but it was Rigr Stafford who began the experiments with young kids; such thing is stated in the World Resurrection LNs:
In the 2nd Volume of the Resurrection; Rigr has conversation with Guren on which he tells him he isn’t sure if his own men or group were working under the First or him; despite everything he proceeded with his own agenda.
Of course, within this, Mahiru eventually got herself involved with the Hyakuya Sect:

Back in those times, Mahiru was observing the progress of the experiments of the Hyakuya Sect, of course, that didn’t mean she enjoyed seeing kids being experimented upon which was the case with Yu; she saw how he was constantly experimented upon until she told him he should find a reason to live no matter what since he had a right to live.
But what was the purpose of her monitoring the experiments the Hyakuya Sect were performing? Was it only to feed her ego? Was it because she enjoyed them?
Mahiru was aiming to use Rigr’s strategies and plan in order to take them with her and make them work since she was aware that Rigr would eventually dance within the palm of the First Progenitor, and for that, it is most known that the only one being capable of not being an influence from the First was Guren Ichinose, which is something stated by Rigr in the 2nd Vol. World Resurrection at 19 LNs.
It could be said that the original plan of Rigr was to use the old experiments of the First while boosting them with the Seraph of the End project in order to defeat him with a more powerful being; but given how he ended up losing it in the battle against him:

It is promptly to say that Mahiru might have seen an outcome within Rigr/Saito.
Returning to the chronological order, in order to achieve victory, she needed allies, she was aware if she told Guren and Guren’s friend about everything, the common outcome would be a crazy idea, but furthermore, Shinoa’s life would have been endangered; what do I mean? Is that even possible when everyone in the story and the readers see her as a selfish monster?
First of all, Mahiru needed backup from the least expected zone, and that is with the Queen of Vampires, Krul Tepes:

But the question goes, why the Queen?
For this, it is clear that Rigr Stafford suggested her the idea mostly because he rejected on turning her into a vampire; therfore, his suggestion went as to ask the Queen Krul Tepes to turn her into one since the plan they had in mind, in order to work, was to execute the First’s in order to remove the sight of the First Progenitor on them; which is why Mahiru Hiragi relied on the transformation of the 3rd Progenitor Krul Tepes; along the knowledge she got from Rigr in order to make the Queen interested:

These events followed suit to a private deal between the Queen and Mahiru, on which they agreed that there would be a demon within their plan, the birth of a new one related towards test subjects of the Hyakuya Sect:

Such statement of their deal is visible when Krul says: “Just like my deal with Mahiru said, the demon transformation has already begun!”
Among this, Mahiru would eventually reveal the whereabouts of Ashera Tepes in her own time

In said panel, Krul states that Mahiru upheld her part of their bargain, meaning that when the deal between them was sealed, one of the parts of said bargain would be the whereabouts of her brother
Within the deal, such events would lead to her eventual transformation as a vampire:

Now, returning to the question about why Mahiru had no choices, this is due to one reason:
The reason comes after the battle she had with Kureto Hiragi in the Catastrophe LNs. After Kureto lost against her, he dialed Tenri Hiragi to inform him about the events going with Mahiru to which Tenri retorts that Kureto would never catch up with Mahiru since he had knowledge of the events due to a deal. Said deal was that if she fulfilled her part, Tenri wouldn’t experiment on Shinoa any further.
Which of course lead to the events of the end of the Catastrophe LN. While those events being the most disturbing ones and one of the reasons the fandom gets triggered, it is to say that tributes were required for the Apocalypse to fall down on Earth.
Now, after the events of the Catastrophe, did Mahiru aim to torment Guren as a floating ghost?
No, they needed to have patience, and one of their missions was to get or rather pick two boys who were enlisted by Rigr Stafford, said boys were of course Yuichiro Hyakuya and Mikaela Hyakuya. But within this, someone came to the plan without the knowledge of the Queen Krul Tepes and that character is Ferid Bathory no less, which would lead to the transformation of Mikaela Hyakuya as a vampire; since it is to be known that Ferid Bathory is quite aware of those who possess the Michaela trait which is still unknown on how he tracked Crowley Eusford in the LNs:

Eventually, the plans into motion would take place after they prepared Yuichiro Hyakuya in order to tame his Seraph powers along with the bond of his demon and the reunion between him and Mikaela Hyakuya.

Of course, at that time, they were aware Shikama Doji would start making his moves towards Shinoa which would eventually take place in Shibuya and within this, the late transformation of Guren into the most powerful demon would take place in order to face down the First Progenitor and eventually lead to the awakening of the Demon Mikaela which are the events of the latest chapters from the manga story.
But now, why does Mahiru is so eager to make everything work? Is it due to her selfishness?
No. One of the reasons of her biggest plan is to protect Shinoa and remove the curse that she has carried in all her life, but within this, she also supports Guren’s plan which is to bring back all humanity along the end of the First Progenitor since he alone is the one who can take him down which is stated by Rigr Stafford; due to the fact that Rigr altered the Ichinose Family using his DNA in order to make his scion that would reject the power of the First, that wouldn’t be able to listen to the commands of the First hence why with the latest chapter, they aim to trap the demon Mikaela in order to awaken the key to face down the First and expell it from the World they live.
Said key relies within Yu, Mikaela and Asuramaru:

The first Key being Yuichiro labeled as the Sun God Aten which name means or is reference to the Archangel Michael.

The second key being Asuramaru labeled as the Sword of Michael but for that, they need to find a way to break the control of the First and lastly:

And of course, the last member to this is Mikaela, the one and only one harboring the Seraph trait and the Michaela trait within him which would give the 3 of them the chance to face down the First Progenitor and banish him forever but then, the controvercy.
Why does Mikaela have to be a demon and why does that even count as saving?
Image taken from Seraph of the End: Vampire Reign - Chapter 99
The First Progenitor’s goal is not to save Mikaela but rather use him by his own goals, and by that, he needs to devour his soul in order to awaken completely with all his real powers and might he once had before he took the current form he has.
Along this, the final goal or plan within Mahiru and Guren’s agenda is to resurrect humanity which was doomed by the First.
While I understand this is one of the most umpleasant thing within the fandom; the story takes in a destroyed world, it takes in an era on which a being with powers close to almighty, close to God, was able to change history and humanity to his own goals and ends.
And for that, for the one that needed to taint his hands with experiments was Rigr Stafford, Mahiru Hiragi that partook in them with the creation of cursed gears along different drugs capable to help the wielders and drugs capable to restrain the First Progenitor to held him or bound him at a certain point which is finally being visible in the story and lastly, give the key to bring back all humanity that perished after the 25th.
In Guren’s case, he is the anti-hero, he is the one that was capable of withstanding the First, he was the scion he needed to face down the First Progenitor admist Guren’s will, he was at the end the guy that was required to trigger down many events but within this, despite all the pain he had to carry on, he needs to fight.
The war is far from over, and just as one of my favorite anti-heroes states.
“Humanity shall win”
What do you think?
