Seeing as most of the demons, barring a few that hid in the shadows, had no issues being in the sun, so they knew I was speaking the truth, and if that is true then the Demon Slayers have a major problem on their hands.
"I know that you Slayers see Demons as nothing but monsters that feast on humans, but that's only true for the previous demons as the ones under me no longer have that hunger." I say as I turn away from them as I watch the rising sun in the distance.
"Muzan's curse gave demons their immortality but cursed them with an unquenchable hunger for human flesh and blood, but now Demons no longer need to consume human flesh to survive! They can once again enjoy the benefits of being human once more! Eating real food without getting sick to the point they needed to throw it up as their bodies could no longer digest it but now they can." I then turn back to look at them.
"I know that my demons had done some heinous and evil things under Muzan's rule, but don't hold it against them as demons have no choice as if they do not consume humans then just like humans who don't eat they would die of starvation, it was all Muzan to blame for everything that they had done, but since I have taken over none of my demons have devoured a single human under my rule." 'Well, not yet at least, but they don't need to know that.'
"…. And the point in you saying all of this is?" Tengen decided to cut in on my speech.
"The point is that Demons are now the next step for humanity! Immortality with none of Muzan's downsides, and I want the Demon Slayers to join us as I see it this war is over as it's time we all take this next step, to bring not just Japan, but the entire world to this next step!" I said as my very being was brimming with overwhelming charisma that even the strong willed Hashira could feel from my presence alone.
"Your not looking at just Japan…. Your planning to rule the world…." One Demon Slayer murmured as their body began to shake from fear.
"Rule the world? No even I know that controlling an entire world on my own would be tedious and time consuming." I said as I waved off that comment.
"Their are plenty of people across the world that fit the role of leaders of their own countries, and so long as I get what I need I don't care what is done, but Japan will be mine entirely." I decide to say as a counterpoint.
"How the hell is that any different than ruling the world?!" Tengen was clearly getting pissed but knew they were at a disadvantage in this situation as a whole.
"Difference is that if I truly ruled the world everyone in the world would listen only to me, but ruling the world through the shadows let's society to stay as it is oblivious to the change happening to humanity as a whole." They do sound the same but their is still major differences between the two as with me ruling the world from the shadows I would have more free reign to do as I please without anything holding me back if I was ruling over it all.
"But now I leave the Demon Slayers with a choice as it is inevitable that Japan will be mine and any attempts to stop me would ultimately be futile, I offer you this, either join me and become the next part in humanity's evolution, or well…." I say as Doma unfurls his metal fans while several other demons show off their claws or pull out their own personal blades as they looked upon the group of Demon Slayers.
"…. Will just be forced to do something really drastic…" I say my piece and wait for their answer.
The tension in the air was palpable, like a barrel of gunpowder left in a dry clearing, all it would take is one spark for things to end in bloodshed.
But under all this tension one Demon Slayer stepped forward and put her hand on Tengen's shoulder and stepped forward, "Is their no other choice than those two options you have presented us?" She asks me.
"…. There is a third way, but I find it unlikely that one would do this if your not interested in the first option, but there is one other and that is if a Hashira is willing to become a first generation Demon and go back with the rest of the Demon Slayers here to find the opinion of the other Hashira and the leader of the Demon Slayers on the prospects of turning into a demon after seeing the change in the new Demon Hashira and whether their for or against it." I go on to explain.
Sure hypnotism and flesh buds can just do it for me and the situation would be said and done but I don't need mindless soldiers, I need followers that can think and act of their own volition and work under their own autonomy not needing me to puppet every aspect of their lives to suit my whims as when you have everything you soon get bored as nothing will spark your interests.
(A/N I mean excluding Kakyoin, Polnareff Okoyasu's Dad and Hag Enya, for some reason(?), he never used flesh buds on anyone else as he either paid them, followed him because of his charisma, sex appeal, respected him, or were genuinely his friend and I think this seen in that part after all.)
"…. I'll do it."
"What?!" "Nee-chan! You can't just go and do that on your own!!!!" Both Tengen and Shinobu shout out at her for even suggesting that.
She turns to look back at both of them, "You and the rest of the Pillars and even Ubuyashiki-sama know that I always wanted their to be peace between humans and Demons, but now if what he says is true and that this really could be the next step of humanity as a whole then I'm willing to take the shot and see if it's true…. If it's not and this was all just an elaborate lie then I'll do what I can to hold them back while the rest of you escape, but if its true then I will come back with everyone and we will discuss with them what we shall do and we will move on from their." Kanae goes onto explain to Tengen and her younger sister why she has decided to do this which leaves them and the rest stunned silent.
Under their quiet but intense gaze the Flower Hashira walked up and stood before me, "I'll let myself be the only one to be turned into a demon, and you will let them leave afterwards right?" She asks me with her characteristically pupiless eyes.
"I keep my promises, now stand still, this will hurt a bit." I say as I reach out my hand before rapidly piercing it straight into her neck.
"Nee-chan!" Shouts out as this is different from how Muzan changed demons with them consuming his blood after all.
"Nghh…." She grunts out as she feels a searing pain go all out across her body filling all of her veins throughout her body, but she has enough willpower to hold up her hand to stop her sister from doing something stupid during the process.
And after a few minutes I removed my fingers from her neck as she feel to her knees before a blood red cocoon rapidly wrapped around her body leaving her inside it.
I then kneel down infront of it, but with rapid speed two pairs of swords are pointed directly at my head by both Tengen and Shinobu, "I wouldn't do that if I were you, I don't know what would happen to someone if their cocoon was broken open to early, but worse case would be they would just turn into a demon similar to Muzan's were, and under the morning sun would spell her death." I say not bothering to look at them as they were still about to attack me.
"If I leave her as it it would take several days to complete the process, however I can speed up the process as I am the new progenitor of our race, and I would rather do that, but as you are her sister I'll leave that up to you, let her stay like this for several days or speed up the process and free her now?" I say as I look at the next Insect Hashira.
She kept pointing her sword at me but I could see it trembling before she slowly put it down, "Free her from…. That…."
I just nod as it's in my best interests she is freed of this sooner rather than later, so I placed my hand on it as I dug my nails into it before it began to pulse with lighter shade of red showing the outline of Kanae's body from in.
The pulse began to get faster and faster like a rapidly beating heart but before long cracks began to appear along the cocoon with it soon opening and cocoon fading away to reveal her sleeping form which Shinobu went down and held her in her arms before I got up.
"We're done here, remember what I said as I will know if you try and keep her away." I say as I get up before turning and walking away as a large doorway appears behind us and opens up to the infinity castle as i and the remaining demons walked through before shutting and vanishing like it was never there.
Seeing as we were gone, Tengen went over to the unconscious Kanae and took her from Shinobu, "Come on, we have to report this to Ubuyashiki-sama." He says before turning to the others.
"Send a messenger Crow to the Lord! Tell him we need to gather all the Hashira and have a meeting that will decide the fate of the Demon Slayers!" He says which the the slayers rapidly nod before preparing a messenger crow and sending one flying back to Headquarters with important intel.
"Haaa, this is gonna be a pain in the ass, I just want to go spend some time with my wives and now I'm gonna have to deal with this shit…." Tengen sighs before he, Shinobu, and a few higher ranked Demon Slayers head back to Headquarters with the unconscious Kanae in tow.
*****
Just realized that these events are all set 5 years before the main story so unfortunately some of the main girls of this series are too young at this point, so obviously no Nezuko or Shinobu(for now) or any of the demon slayer girls from Tanjiro's time as they would be 10 or 11.
So realistically only Mitsuri and Kanae would be eligible to be his at this point in time as they are both 15 and 16 respectively.
