Right now we can see Sukuna walking around a village he had just arrived at the world of Demon Slayer well in the sengoku era that is but the strangest thing happened was he was walking through the people how you ask? Well he's a curse which are technically spirits to make it more simpler if one can't use or has no curse energy they can't see him nor touch him unless he let's them.
"Wow this place really looks amazing" Sukuna said as whistled through the crowd with the tune of the konosuba outro song it was calming.
Just as Sukuna was about to head to the next village he overheard something that made him giddy
"Hey did you hear?" A bald man whispered to another man
"What?"
"I heard that one of the Tsugikuni's ran away"
"Wait seriously!?"
"Yeah it was one of the twins that was supposed to become a monk he was able to beat a samurai! He was made heir but why did he ran though?"
"I don't know maybe he doesn't want to be the heir"
Sukuna who heard this was sure where he could find Yoriichi he just had to ask.
A few hours later.
Sukuna's POV
ALRIGHT THIS IS BULLSHIT!
Why was I angry? Well turns out when I asked the location for the Tsugikuni estate as I allowed myself to be seen they got suspicious since apparently everyone knows where it was and when Yoriichi left exactly the same day arrived it was even more suspicious!, So I had to run away from the village and find the rice Field Yoriichi Meets Uta at! And apparently I can't even interact with Yoriichi or Michikatsu! Since it would change their fate! So here I am stuck in a cave thanks to the system trapping me inside and all I have is this screen in front of me!
[Sealed!]
The system has sealed the user for 10 Years until Yoriichi becomes a demon slayer due to the body of the host being sealed in a confined space curses will protect this area.
Current status: Sealed in a Boulder.
Remaning time: 5256000 Minute's till released
'Damn system I can't even leave this world! And now I'm stuck here for 10 years!?!'
And that's how 10 years of boredom began
1st Year.
You know I regret accepting this quest why didn't I just wait till midoriya fights stain or something but no I had to hurry up well now I'm stuck in a Boulder like that nine tails folklore back in Japan except that a monk won't come here and im pretty sure people won't die from touching this boulder.
"Hey system why can't I just leave this world??"
[Due to the stupidity of the Host he will be trapped here for years but that's not the only problem he might stay here as long as muzan isn't dead, The user can fight muzan if he had the power of 10 PURE fingers not just the rank but if the user waits till muzna gets poisoned he could fight him by himself.]
"Oh so my best bet is A. Let everything happen but make myself know as a spirit for the slayers and kill muzan at his poisoned state or B. I could grind missions and try to get to Pure finger power.."
[Yes.]
"Welp time to think of a better title then king of curses!"
2nd Year
Well some things happened...
People found the cave and when they did thanks to the help of the curses I made implanted with my eyes on them I was able to see around the area all of those who went near the cave got sick and some of them even died!, Now the people have been calling this place the cave of spirit's or the cave of death but some Demon Slayer's came here to see if it was a demon of course they didn't have breathing styles yet since Yoriichi is still 11 years old he won't become a Demon Slayer till he's 19 which is basically the day he would go all Obito and kill all demons.
They left after a few visits thinking it just a sickness or virus that can be obtained here that killed the people since none of them who died had there's bodies have gone missing but the locals still stay far away from here... Well until now.
"Please don't eat me!"
Now in front of me was a short man with a tengu Mask....did I forget to mention that I'm actually trapped in a cave near the Swordsmith village? Funny right
"Relax I won't eat you..." I said to him as he apparently doesn't see the chains on me.
"Wait!?! You won't I thought you were a demon! Wait a minute! There's a hole above you! And sunlight is leaking through you aren't a demon!"
Wow he said that in one breath?
"Look shut up but let's introduce ourselves you start!"
"I am the Mighty! Kotetsu Tetsu!"
(WOOO SCENE BREAK!)
Kotetsu is the child Tanjiro meets in the Swordsmen village he doesn't have a last name so I made kotetsu the last name! This is accurate since kotetsus ancestor is the one who made the Yoriichi doll! But anyways THE PLOT THICKENS!
(SCENE!)
"I'll become the best Swordsmith in the village!"
"HEY DONT LOOK AT ME LIKE THAT I BET YOU HAVE A STUPID NAME!"
"Ryomen Sukuna The King Of Spirit's"
I said to him with a smirk he looked at me then-
"KING OF SPIRIT'S!?! YOU!?! WAIT SPIRITS ARE REAL!?! well demon's exist but SPIRITS!"
'Had to say something instead of curses this was my best bet'
"Yeah so can you go away now?" I looked at him as I yawned
"Wait! Since you're a spirit! Are you the one causing people to die from a unknown disease! Wait will I die too!?!"
"Pretty sure you won't I mean you don't stink of curse energy so your fine"
Yup that's right curse energy is the reason people are dying since cursed energy doesn't exist here and even if they did the only place I could feel curse energy was in a smelting area where I'm pretty sure where all the broken blades go...
"Wait curse!?! They were cursed!"
"Yeah I mean curses are attracted to my energy so yeah.."
It was both a lie and truth since I made the curses but they are also attracted too it.
"Well can you please stop!"
He pointed at me.
"Look Kotetsu i could do that but I can't because as you can see" I said as I lifted up both my hands that were bound to the Boulder.
"Wait chains!?! What happen?!? Aren't you supposed to be the king of spirits why are you chained up?!"
Man this guy likes shouting... Time to use the old excuse
"Some white haired basterd that wanted to have a fight tricked me"
"Wait so you can't stop the curses!?! People will continue to die!?!"
BRO PLEASE STOP SHOUTING I HEAR EVERYTHING 10X BETTER SO MY EARS HURT LIKE HELL
"Meh just give me like 8 years and it will stop"
Wait do I have too wait.... Hey system can I buy something to help me with This??
[Ding!]
Blessed Talisman! X20
These talisman are used to seal cursed spirits
System note: The Dumbass User could give them to kotetsu and make him surround the village with it.
Cost: 1 Extra Year.
Hey! One extra year!! Tsk fine this would be a good chance to get some good reputation with the slayers.
I purchased it and felt myself become more weaker but ignore it for now the talisman appeared in my hands while kotetsu looked dumbfounded since I just pulled these out of thin air...
I throwed it at him and he looked confused
"Put Them around the village and you'll be fine.."
He looked at it and me then bowed 90 degrees
"THANK YOU RYOMEN-SAMA!!"
Wait.... Sama.....I won't become a religion won't I?
