Alternate Dimension...The Infinity Castle..
Upper Moon 3, Akaza, stood in the hallway of the castle...The Hallways of the Infinity Castle were endless, the surroundings were bright but quiet..
The fact that I was summoned here means...An Upper Rank was killed by the Demon Slayers-..?!
"Wrong.."
Akaza perks up, his eyes glancing around as he heard the echoing voice of Muzan Kibutsuji himself and before Akaza knew it, the sound of a biwa string flicking was heard and Akaza found himself behind a sliding door, being teleported inside a room..
The Sliding doors opened up, allowing Akaza to step out
His eyes glanced around again and there he saw The Twelve Demon Moons..
All of Them..
From the Upper Ranks to the Lower Ranks, with the Upper Ranks Standing on the Higher Floors and the Lower Ranks standing on the Lower Floors below the Upper Ranks
Akaza's eyes looked at each Demon present in the meeting..
Upper Moon One, Kokushibo
Upper Moon Four, Hantengu
Upper Moon Five, Gyokko
Upper Moon Six, The Siblings Gyutaro and Daki
The most Notable Lower Moons were also currently Present..
Lower Moon One, Ubume
Lower Moon Two, Hairo
Lower Moon Five, Rui
And Lower Moon Six, Kyogai
But Akaza's eyes shifted back to the Platform in the Middle and his eyes slightly widened..
Doma, Upper Moon Two, was in a crouched position in front of Nakima and Muzan Kibutsuji himself but that wasn't the surprising thing in the meeting yet
Looking closely, All the Demon Moons noticed on how badly Injured Doma looked, his injuries weren't healing and it seems he was clutching his decapitated arm and trying his absolute best into hiding the pain
Meanwhile, Muzan was writhing in rage as his fists were clenched tightly and his head was down as visible veins appeared on his neck and fist
Suddenly, Flashes appeared into the heads of the Demon Moons, it showed a certain Demon Slayer with Hanafuda Earrings, Black to Red Hair, and a familiar mark on the Slayer's forehead, a Mark which was all to familiar with Kokushibo and Muzan
Soon enough, the Higher Floors where the Upper Moons stood on and Lower Floors would be brought down and up, like an elevator, being brought to the same level of the Platform where Doma was crouched on
The two meetings were now mixed and probably for the first time in a few years, the Upper Moons and Lower Moons would be having a meeting together
Muzan, who had finally calmed down, let out a frustrated sigh as he looked up now but his fists remained clenched
Letting out another sigh, Muzan turns back to his table that was filled with books and lab equipment such as test tubes, beakers, and etc.
"..Lower your heads and Crouch Down.." Muzan finally spoke and suddenly, the Demon Moons all but Kokushibo and Doma (since they were already crouched and kneeling) felt a great pressure upon them as they were forced to kneel
Moments of silence passed, the sounds of book pages flipping were the only sounds heard as the Lower Moons were clearly nervous
"..Why is it that you demons in the lower ranks are so weak and easily killed? Each time you see a Hashira, the only thing in your minds is run.."
"And as for you in the Upper Ranks...Your objectives haven't been completed. Non of you all have annihilated the Ubuyashiki Family.." Muzan wrote on his notebook before putting it down
"..What about the Blue Spider Lily?"
Non of the Upper Moons nor Lower Moons said anything and Akaza only clenched his fists as his nails dug deep into the floor
...
...
Muzan slams his hands on his table as some of Beakers and Test Tubes exploded into pieces by the sheer pressure Muzan put, this pressure was felt by Demon Moons as Muzan gritted his teeth and obvious veins appearing
"Why can't you find it after so many hundreds of years?"
More of glass equipment in Muzan's mini lab broke and exploded in millions of pieces "..I'm starting to question...on why you all even exist.." Muzan says through gritted teeth, writhing in rage
Hantenegu crawled forward as he kept bowing "Oh! Please Forgive us! I beg you..!"
Akaza only gulped before Kokushibo spoke "I don't know what to tell you. Ubuyashiki...Is a Master at concealing himself.."
Daki, Gyutaro's Sister, spoke also after gulping "I-..I don't know what to say either, Search and Detection isn't our strong suite either, we're at our wits end.."
"Tch.." Gyutaro looks at his sister who was crouched beside him "What do you mean 'we'? I could-.."
Gyutaro now is cut off by Muzan, who now spoke again "..The one thing I dislike is change.."
"Changes in circumstances."
"Physical Changes.." Muzan briefly glanced at Doma, who still had multiple scars and decapitated arm, but were all slowly healing
"Emotional Changes.."
"In most cases, change of any kind means degradation. It's decay, I prefer the unchanging. A Perfect unchanging state that lasts forever.."
Muzan now looks down upon at the Demon Moons, his glare sharp and eyes narrowed..
"For about 100 Years, a Upper Moon was nearly killed.." Muzan clenches his fist before he lets out a sigh
"..From this point, I'm giving you all one Simple Objective, a Common Task.."
"Kill The Demon Slayer with Hanafuda Earrings, the Same Demon Slayer that I have shown in your heads, Kill him."
"That is my order to you all, all of you will combine your strengths to find and kill this slayer.."
Doma, who had been quiet for the entire meeting, would now finally stand up slowly. His body was shaking but his smile was back but he still was clutching his decapitated arm
"One second, Muzan-sama. Although I confess that the idea of forging new bonds with my comrades... it is absolutely out of the question that I leave someone to kill him.." Said Doma
Muzan stared at Doma for a few seconds before he puts up a deceptively sweet smile
"Really? Do you really think I can send you to face the human who almost killed you? It would be a shame if he didn't miss you this time. Maybe I should send Akaza."
Doma stared at Muzan, shocked and for the first time, Doma actually spoke back in actual anger as his frontal veins burst "AND I TELL YOU NO ONE WILL KILL HIM BUT ME! IT WAS LUCKY! YOU UNDERSTOOD?! WHEN I HAVE IT IN FRONT OF ME, I WILL FREEZE HIM! YOU UNDERSTAND? PIECE OF-.."
Doma's sudden outburst is cut off as Doma disappeared with Nakima teleporting him elsewhere to avoid angering Muzan
Akaza stared slightly shocked "I don't know who this human is, but I would like to meet him...To think that he made Doma angry, must be quite the freak.." Akaza thought
"..That's right Akaza, I agree." Muzan now says, since he was able to hear his thoughts
"Hm?" Akaza looked up
"I changed my mind. Here is your order: The Lower Ranks will be on a mission at worst to kill on sight the Demon Slayer who wears the hanafuda earings and a red mark on his left forehead, or at best to amputate his arm and leg to bring him back to me.."
"To the Upper Ranks, you will have to transform him at all costs, but if he resists too much, kill him on the spot.."
"Am I clear?"
"Yes, Muzan-sama.." The Demon Moons all replied in Unison
-----
Once after the meeting ended, Muzan and Kokushibo remained. The two strongest demons side by side as they started talking to each other
"You said he was dead...Kokushibo.."
"Even after about 300 years, the memory of his blood on my blade is still ingrained in my mind. he (Yoriichi) is dead. Nevertheless.." Kokushibo looked down briefly
"In this world where we demons exist...Would reincarnation be possible?" Muzan glances at him
"..If it was, then we're grave danger.." Kokushibo says before he stayed silent to think "Unless, the Slayer is his Descendant?" He turns to Muzan
"..Did he ever have a wife and child?" The Demon King looks at Kokushibo for confirmation
"..He had but they were killed, according to him.."
Muzan looks up for a moment before glancing back "I'd assume the Slayer is his descendant then. If it was truly him then Doma would be dead...The Demon Slayer must still be inexperienced, not yet on his level but he will be.."
The Demon King clenches his fist tightly, the memory of that night Hundreds of years ago replaying in his mind..
"No matter...make sure you kill him with your own hands before he cuts the blow with a final gasp.." Muzan glances back "Am I clear?"
"Yes, Muzan-sama.." Kokushibo nodded
With only a nod, Kokushibo stepped back and disappeared
