PART 1

______

~upper rank meeting~

everyone knelt down before kokushibou and worshiped him, even if the worshiping was filled with fear and yet respect.
The last few nights they had dozens of meetings for various reasons, one of the reasons being upper rank 1 was killed and that meant Douma , upper 2 , became upper 1 and Akaza was now the new upper 2.
In the beginning, kokushibou wasn't worried about that one boy who wore the earrings with the sun symbol , I mean just because he now wears them like yoriichi did doesn't mean he was as strong as him or yoriichi was, right?

Apparently he was wrong, Tanjiro slowly came too close, in turn, kokushibou didn't have a chance to meet the boy himself without him noticing it directly,
And recently HE, kokushibou THE demon king, had problems finding a simple boy and even the upper rank demons had problems with it.

And since this is, they meet almost every day to exchange information about the boy.
In fact, the upper rank demons felt insecure, and they were among the strongest demons, but after the loss of upper rank 1 nothing was like it used to be.
They were scared of dying.

Gyutaro, the douple upper rank demon that was now upper 5 , raises his hand.
"You may speak up Gyutaro" Kokushibou said in his useally dark tone.
"Dear lord , I heard about a man who seems to be staying near a lake in Tokyo right now, he knows a lot of things." Gyutaro said as he looked up a bit but got pushed into the side by daki, his younger sister that was also now upper rank 5 ,"don't look at the lord like that idiot" she whispered to him.
"In Tokyo? Does anyone have any other information" The demon king asked but no one raised they're hand for a permission to speak, they all stared at the ground.
Even Douma and Akaza stayed silent and just had a stare battle at eachother.

Kokushibou let out a sigh ,"say nakime, are you able to teleport me to Tokyo by any chance" Kokushibou said and turned to the side to look at the woman that was sitting on the floor with her wooden biwa in her lap.
The hair was covering almost her entire face like always.
"Yes" a simple and soft answer from nakime.

"Does anybody have any information about the man" Kokushibou asked , incase that the man may be dangerous even tho he knows that no one could defeat him.
Daki raised her hand," I believe his name is Muzan and that he heals slower then other demons" Daki said without giving a look to the lord.
this only drew Kokushibou's mind to the man, he healed slower than other demons? how is that even possible?
He's definitely weak and dies fastly , he may just rips of his head when he got the information that he needs so badly.

"You all may now disappear , Akaza , keep an eye on the hashira's with Douma"
Kokushibou said so in case the hashira's would hear about that Kokushibou left the infinity castle , they wouldn't be able to slay his head.
Akaza cursed himself for getting send on a mission with Douma TOGETHER.

-biwa sound-

The upper rank demons disappeared to the place where they were before the meeting.
"Nakime ,bring me to Tokyo" Kokushibou commanded and in the next few seconds another biwa sound was heard.
