Hello everyone, good morning, I hope you get to have a great day, remember to stay safe!

One of the things the fandom has been wondering it’s related to why or how Shikama was able to pop in the middle of the conversation between Krul and Shinoa; therefore, let’s talk about said topic, shall we?
But, before we start wondering why he possessed her easily in chapter 98, let’s recall some events to explain why such event happened
As far as we know, Shikama Doji was able to possess Shinoa by taking Yu and Ashera as hostages back in chapter 74:

Of course Yu and Ashera weren’t rivals to the First due to the inmense amount of power he has; thus it lead to Shinoa go in opening her heart and rescue them; this only allowed the First Progenitor to fulfill one of his many tasks to do to fulfill or achieve his dream of revenge or whatever he seeks within the story. As far as we know, his past and all his actions are shrouded in mystery.
But now, returning to the main topic, we might recall that Shikama took total possession of Shinoa in chapter 76 after Ferid aimed to make the First appear in a “weakened state”, and you might wonder how I can state that.
For that, let’s recall that the First was taking Shinoa’s possession at his own rythmn, but of course Ferid didn’t allow such thing:

Within this, the First Progenitor slowly started to “play” around with the vampires that sided with the humans; until Rigr Stafford came in and started to have a serious fight against the First; eventually, the events on which Guren used 3 sinful keys to restrain the First Progenitor came in; but within this, the First Progenitor stated something rather curious:

He stated he could resist the effects of the Sinful Keys but that’d be harmful to Shinoa since she was still a human that didn’t go through a vampire transformation state.
Therefore, does this mean the sinful keys failed?
No. But why or how can I state such thing?
The Sinful Keys alone were used for one sole reason asides from buying time, what could it be?
Correct. The sinful keys used against the First were used mainly to seal him or trap him within one sole body but, how can I be so sure about this?
Back in chapter 57, Kureto got possessed by the First, though, his demon Raimeki managed to withstand such event, allowing the First to roam freely; but then again, how can I be so sure about this?
That’s easy:

Shikama’s shadow heading towards Shinoa’s location, that can be displayed in chapter 66 and 67
The shadow that is circled in the picture above, it’s actually Shikama Doji’s shadow; same issue happens in chapter 73

Shikama heads to visit Asuramaru
Therefore, it can be said that Shikama had freedom to invade other hearts easily in order to achieve his goals or seeking ways to invade and finally possess Shinoa’s heart; therefore, this shows that the Sinful Keys held down certain effect, and that was to restrain his freedom:

We can state that if Guren had the 7 Sinful Keys, the effects would have been much bigger compared to 3 sinful keys; but that alone was something Guren and Mahiru aimed; and that is to save Shinoa’s life from the First Progenitor without the need to kill her or sacrifice her.
But now, why did Shikama reappear after they used those 3 Sinful Keys?
That’s easy, if many might recall, Shinoa and the First Progenitor might not be close in terms of fondness compared to Yu and Asuramaru’s bond as wielder and demon; but, their link goes in a different form; what do I mean?
It means that whenever Shinoa would be endangered, Shikama would protect her even if it’s focused for own personal selfish objectives and of course, that’s awfully displayed in the next panel:

But of course, about how this change happened will be explained in another theory.
Returning once again to the main theory, it can be concluded that the Sinful Keys were only there to stop the First Progenitor from roaming freely to his own will; hence why when Mahiru used a special drug, they delayed even more the moves of the First Progenitor to track down the demon Mikaela.
As for Shinoa and the reason she was possessed easily, it’s because the door to her heart was left open when she went to save Yu; despite supressing her emotions, she already stated the side effects of it:

Correct, her body no longer belongs to her alone after the possession and her rescue; therefore, for the First Progenitor is easier to take over her when there’s something that catches his interest forehand; such as tracking down the demon Mikaela.
But now; many might wonder why Shinoa is so easily to possess and perhaps the conclusion is because her desires alone were released but, in fact, that’s not the issue; what do I mean?
Shinoa Hiragi doesn’t views herself as someone worthy to save.
Perhaps readers might dismiss the idea of such thought but Shinoa has been carrying a sense of guilt for a long time; and that is something visible in the last volume of the Catastrophe at 16 LNs; after Shikama returned to her; Shinoa learnt that her sister sacrificed herself so she could live up a more peaceful life; to add more to this, in chapter 72, after realizing that her sister was protecting her from a monster, she deemed herself as the only one that held down the path of happiness to her sister and Guren Ichinose; furthermore, the fact that she allowed Shikama Doji possess her alone, it was something that despite she aimed to save her family, it also caused damage to the outside world.
Those emotions alone, make her doubt if she should keep going or not.
But well, the story must keep going, and we can only wait to see how this girl will eventually evolve in future chapters.
