(this is for fun, no one come at me.)

at the swordsmith village

Muzan has grown more relentless recenty, due to the demon slayer corp actually managing to kill uppermoon 6, he isn't AS dumb in this au, so he was having some demons target the sword smith villages, no matter how far and how much they move, demons always attacked and found them, so much so till fear and uncertainty arose on both the villagers, and the demon slayers, though they eventully went to a more hidden area, in the darker moutainscape.....though another issue came....

---

more demons.. though no loyalty to Muzan, if so they were more like small nuisances rather then actual threats, as they mostly kept their tom foolery outside, though the issue was that they were smart, often stealing food or maybe even mats, hough the lead, actually having a idea....actually made a alince with 1 of the groups of imps, and their was a deal of the sort, they give imps spare materials, they eradicate other demons in the area while there gone

---

its a fair trade...however, people grew uneasy on how smart the imps were....somehow making their own weapons or hides....even make alliances with other imp groups. or learned other skills such as taming, building,

smithing-

but what shocked them the most was the fact they found a blue spider lily....and gained immunity to the sun...like how tf did small imps find a flower before demons who lived hundreds of years....-

but it made it their interest, even if their still demons....so they kept them around,...

---

though 1 day, a group of demon slayers visited guided by their katsugi , to manly get their swords fixed, as they gotten damaged on a mission, and apon arrival they were greated like usual.....though some did notice the demons....including the stone hashira, gyomei...which were originally going to fight until a villager spoke...

"don't worry, they don't bring harm..just leave them alone..."

the slayers were shocked......demons...being a ally...immposible-
