(First up is the bad ending! After their bad ending is finished fit will rewind a bit and that's where the good ending will start!)

"MISSION!" A crow squawked while flying towards the snow pillar, Y/n L/n.

"Oh, hello C/n (crow name)!" Y/n turned to face the crown while reaching out their arm for it to land on.

"Head to (random mountain)! You'll be accompanied by other pillars. Hurry Hurry!" C/n soon flew away while Y/n watched.

"I should head there. It's quite the ways away.." Y/n sighed as they began running towards their destination.

Y/n jumped down from a tree as they greeted the kamaboko squad and other hashiras.

"Good Morning everyone! I apologize for how long it took me to get here!" Y/n apologized as they looked around.

"It's alright but we believe the demon king may be on this mountain.." Shinobu said.

"I'm sure with all of us here we'll be able to end this once and for all!"

'I wish I didn't say that.' Y/n thought as they dropped their blade.

They felt Muzan let go of there neck, letting them drop to their knees as Muzans blood trickled through their veins..

"Y/n-San!" The 3 younger boys (Tanjiro, Zenitsu, Inosuke) yelled as they ran to y/n's side. They weren't sure what to do from their. Y/n's body was twitching and shaking as blood ran down their mouth.

Eventually they stopped as their head began to slowly raise and turn towards Zenitsu.

A hard hit was landed on Zenitsu as y/n stood up. The smile that was plastered on their face was agonizing. Their eyes and soul were filled to the brim with hunger.

Everyone quickly stopped as they looked at the once lovable snow pillar. Y/n was now stalking towards Inosuke.

Everyone was so lost that they couldn't wrap their heads around it, but..

.

.

.

They had to kill Y/n. Weather they wanted to or not. Y/n was a demon and they were hungry, starving even.

The mist pillar, Muichiro decided to deal with y/n by quickly ending it.

He had slashed her neck and it had fell to the ground. Y/n was dead.

...
(Good ending)

Y/n held the back of their neck as pain sprouted throughout their body.

Muzan had injected his blood into the pillar while he was trying to escape to sunlight.

Y/n's breathing became heavy but short as their eyes slightly filled with tears.

They were sat on their knees with one hand of the ground while the other was still on their neck. They slowly looked at everyone else, who were shocked.

"I don't want to be a demon.." Those were their last words before the reality they once knew was gone, they were a demon.

The water pillar quickly pulled y/n into some shade before they attacked anyone.

Y/n watched as everyone watched their every move. Y/n was raging with hunger but a small part of them knew that they had to be patient. Y/n knew they couldn't hurt them even if they tried.

"I have to... protect humans!" They quickly yelled as they looked at everyone.

Maybe, just maybe, the master would spare them and allow them another chance.
