Demon Slayer Halloween Headcanons, Finale.

Happy Halloween everyone! This is the final part of my Demon Slayer Halloween Headcanons. This one is covering any characters I forgot to do, or couldn't fit into the other three parts. I would like to clarify that I have not read the manga and only have information up to the current season of the anime.

Have a nice read and night!

Sumi, Kiyo, and Naho: These three went out as a Bumblebee, Ladybug, and a Butterfly respectively. Once they got back to the mansion they held a candy trade with the older kids. It was Sumi's idea to dress Gyomei up as a mummy.

"Trick-or-Treat!" "Give us something good to eat!" "PLEASE!"

Makomo and Sabito: Sadly these two are unable to dress up. So, they spent the whole night scaring any and all demons that got too close to Mt. Sagiri. Makomo left some candy on Urokodaki's bed so he can feel included.

"Now WE get to scare the demons!" "OH! HERE COMES ONE NOW!"

Sakonji Urokodaki: Urokodaki spent the night alone for the most part. Nezuko, Tanjiro, and Giyu came for a visit a few days before so they could have a small party together. He nearly had a heart attack when he found the candy Makomo left.

*Confused Screaming*

The Ubuyashiki Family: No one from the Ubuyshiki family was able to go out, for their protection. The children were all still allowed to dress up and have candy, which was delivered to the house.

"Have a safe and nice night everyone!"

Aoi Kanazki: Aoi was wearing a butterfly costume, only because the girls asked her to. She helped get everything ready and was allowed to take the night off. She did not even try to stop Inosuke from attacking Zenistu.

"As of 5:27pm, I am off the clock. He's all your's."

Tamayo: Tamayo stayed home to get some work done. She gave out candy to anyone who came by. She was happy to see Nezuko and Tanjiro when they stopped by.

"How has tonight been for the two of you?"

Yushiro: Yushiro was shooting daggers at anyone who Lady Tamayo 'paid too much attention to.' He ended up hitting Tanjiro and was forced to apologize.

"I did not throw him-" "I .DON'T. CARE."

Chachamaru: Chachamaru spent the night peacefully sleeping and occasionally getting pets from Yushiro and Tamayo.

"Meow?"

(Why can't I find a happy gif of this kid?)

Senjuro Rengoku: Senjuro also dressed up as a lion and spent the night Trick-or-Treating with his big brother. It took him awhile to gather up the courage to talk with everyone else, but he ended up making a lot of friends at the party.

"H-Hello! Happy Halloween!"

Hinasturu, Makio, and Suma: Couples costumes are adorable, aren't they? These three went as flashy dragon queens to match Tengens flashy dragon king costume. (It was Suma's turn to pick the costume theme.) Hinasturu and Makio apologized for Tengens sudden fireworks display at the Butterfly Mansion.

"We are so sorry..." "I...thought it was pretty though..."

Hotaru Haganezuka and Kozo Kanamori: Swordsmiths don't have much time to rest, even tonight. These two had to deliver swords all night long. If you think Haganezuka gave Tanjiro a break than you are crazier than Enmu.

"YOU GET BACK HERE YOU BRAT!" "Chimes! Quickly, GET THE CHIMES!"

Biwa Demon, Nakime: Who do you think summoned the Upper Moons? She will never admit to it, but it was a fun night.

"....:)...."

The Shinazugawa household X slave fem reader!

She is an exotic demon slave because she is from another country, been thrown all over the place, fought another demons that are bigger than her, killed one of her past owners, and they choose her because they heard rumours of her never harming children and instead protecting them like a big sister. She could manipulate bones, has a big spear made of a huge demon spine she killed, and can easily rip bones out of anyone, she wears the bones of everyone she had killed to keep as trophies and turns it into accessories. She is literally a Savage Skeleton girl. She a bit insane in a deadpool way but flirty like knockout

Summary: The eldest Shinazugawa brothers head out to find a guard Demon for their younger siblings, but are low on money... But then they found you, a little weirdo Demon, but you should be able to keep the kids safe, right?

Warnings: Slavery

A/N: Slave!AU, Demon Slaves, Sanemi Shinazugawa, Genya Shinazugawa, Female Reader, Demon Reader, Teiko Shinazugawa, Hiroshi Shinazugawa, Sumi Shinazugawa, Shuya Shinazugawa, Koto Shinazugawa

When the two oldest Shinazugawa siblings went to the Slave House to see Demon slaves, they didn't expect to see you there… But let's back up a little bit.

Sanemi and Genya had gone to the house to find a guard dog aka guard Demon to take care of their siblings. Their late father had been abusive, but mostly towards their late mother.

Both young men wanted to keep their siblings safe from any harm and while a dog would have done the deed, Demon would be able to play with them, clean, and cook while Sanemi and Genya weren't there.

But damn, Demons were expensive!

"What the Hell…" Genya grunted as he rubbed his eyes, "How can a Demon cost this much?"

"Yeah, I'm starting to lean towards a dog more and more," Sanemi growled in frustration. They had some money saved, but feeding 7 people cost a lot��

"Maybe this isn't a good idea…?" Genya frowned and his older brother nodded, but before they could turn and leave, a man appeared behind them.

"Are you looking for something specific?" The man asked and the brothers shared glances with each other.

"Yeah, but we doubt what we are looking for is in here," Sanemi grunted, and the man smiled, "Depends. What do you want?"

"We need a guardian for our younger siblings-!" Genya was saying but his brother shot him a glare, "Shut up Genya!"

"A guardian, huh?" The man nodded, "Well, we have some great guardian Demons here that would no doubt satisfy y-!"

"Thanks but no thanks." Sanemi frowned, "We don't have the money for one so we'll just leave."

"No money, huh, and kids to protect…" The salesman nodded and any other time that would end the conversation, but this man wouldn't give up, "What about if I told you there is something that would fit your taste and prize rank?"

"I'd say that you are full of shit," The oldest brother said and the man laughed, "Come, follow me!"

The brothers shared glances and the man laughed, "Don't worry, looking doesn't cost you anything!"

He was right about that. So the brothers followed the salesman to a locked door and watched as he dug out a key and unlocked the heavy padlock, uncovering stairs to a basement.

"Come come!" The man smiled and the brothers followed him into the darkness… And their eyes widened as they smelled the blood and mold in the air. An awful combination that made their noses burn.

"Pardon the smell," The salesman chuckled, "We don't actually take other customers down here."

"W- what is this place?" Genya asked and the man chuckled as he turned on the lights, and showed the cages full of what appeared to be feral Demons.

"This is the place where Demons are brought to die." Sanemi frowned as he shot a glare at the salesman, "Right?"

"Something like that, yes." The man nodded as he led the brothers to a cage with a female Demon hunched at the back of the cage, sleeping. That was you.

The man chuckled as he looked at the brothers, "This here is a rare one. It was imported from abroad where it was actually a fighting arena Demon. They called it Bone Demon because of its abilities to fight and take trophies from its kills."

"An arena Demon!?" Sanemi snapped, "Are you crazy!? Those things were made to kill! That's all they know!"

"Well, yeah, but-!"

"But what!?"

"Well," The guy shrugged, "The truth is that it killed its previous owner…"

"So it isn't safe!?"

"Well, you didn't hear this from me…" The man looked around to see if anyone else was listening and then continued, "That fucker had it coming."

"What?" Sanemi and Genya blinked and the salesman nodded, "Rumor has it that he was beating his own kids and the Demon took him out for it."

"Then, why is she being put down if she was only protecting the kids?" Genya asked, but Sanemi frowned, "Are you stupid? When Demon kills its owner, it's deemed dangerous, no matter what the circumstances were."

"Yeah, I'm a dreamer myself and always want to believe in second chances." The salesman chuckled, but he didn't sound to reassuring.

"Look, these Demons are going to be put down anyway, so why can't I give them a new home and earn a little while doing so?"

"And how much do you think you earn with this plan of yours?"

"Well, how does 600 sound?"

That offer was beyond good, it was almost too good to be true. The brothers shared glances and frowned as they turned their attention to your peacefully sleeping form. You looked so graceful and like you were in peace… Maybe you weren't that bad?

"Still, it needs a ton to eat…"

"Well, there is a… You know?" The salesman said and the brothers frowned, "Know what?"

"There is a rumor, but it's only a rumor…!"

"Just tell us!"

"Okay! Demons, if you give them fresh blood they can go on for days without anything else to eat!" The man smiled, but the brothers didn't share his excitement, "Duh, everyone knows that Demons need mean and blood-!"

"I meant human blood!" The guy snapped, "Give it some blood and you don't need to feed it!"

"That's illegal!" Genya cried out, but the man shook his head, "Look, everything that happens or is talked in here stays between us!"

"Still, that Demon is way too dangerous!" Both brothers frowned and the salesman sighed, "Okay, here is my final offer, 100 and it's yours!"

"Cheap!" Genya gasped and Sanemi frowned, "Why so cheap suddenly?"

"Look, it costs me almost 500 to put it down and it has a good bloodline! If I had any spare time or funds I would breed it, but I don't! So?" The man sighed, "Do you take it?"

Genya swallowed nervously as Sanemi frowned, "We will take it but only if it has a kill switch installed."

Ah, the kill switch. A collar that could capitate and therefore kill any Demon that could be deemed as dangerous to innocent humans. The salesman sighed as he nodded, "Alright, I'll lock one around its neck and you can take it home right away."

"Good." Sanemi nodded as he dug out the money the salesman wanted and handed it to him, "Make it hasty, I can't stand the smell in here."

"Yes yes," The man nodded as he went to pick up a collar for you. Genya though, glanced at his older brother in worry, "Big brother, is this really a good idea?"

"It's cheap, it can protect our siblings and it has a collar to end its life if it acts out." Sanemi nodded, "It has to do."

Genya wasn't as sure as his brother was, but he trusted his older brother, no matter what… And if you ended up becoming a risk, you would have to be taken out.

The brothers watched the salesman pick up a collar and open your cage enough to slip the kill switch around your neck while you were still in deep slumber. While he was at it, he picked you up so he could hand you over and that's when you started to wake up from your sleep.

"Morning sleepyhead," The salesman chuckled as he placed you on your feet in front of the Shinazugawa brothers, who blinked as they got a good look at you.

For a Demon, you were a petite little thing. It was almost impossible to believe that you had taken out Demons bigger than yourself in the fighting arena. You yawned and rubbed the sleep off your eyes as you inspected the brothers before you.

"Howdy…" You greeted them quietly and the salesman laughed, "It's a little groggy after a long sleep, but should wake up in any minute now!"

"Great, we will take it to the car and get out of your hair." Sanemi nodded as he grasped your upper arm and yanked, "Come on, we're leaving."

You yawned but nodded as you followed the oldest brother out of the dark stinky basement, Genya and the salesman following quickly behind you two.

"Remember!" The man shouted, "No refunds!"

"Fuck off…!" Sanemi growled under his breath as he, Genya and you left the Slave House and took you to their car. It was a dark rainy day so there wasn't sunlight to worry about as they got you into the car.

As Sanemi got into the driver's seat and Genya next to him, you were already feeling better. By the time the car took off, you had woken up and done a perfect flip with your personality.

"Hey hey, are you my new owners?" You asked happily and the brothers shared confused glances before Genya looked at you, "Yeah…?"

"Fantastic! Terrific even!" You giggled as you grinned from ear to ear like a Cheshire Cat, "Haven't had an owner for a while now!"

"Because you killed that fucker?" Sanemi asked and you hummed like you were thinking something hard.

"Yeah, he was a bad man," You nodded, "But his kids? They were sweethearts!"

"You protected them, right? From the guy you killed?" Genya asked and you stilled as you stared at him… And then you looked down on your feet, "Kids are precious. So innocent, so sweet. Strong must protect the weak."

The brothers glanced at each other. So far, you didn't appear like a bloodthirsty arena Demon… Genya smiled a little as he looked at you, "Well… In your new home at our place, you will have kids to protect again?"

"Kids?" You repeated and the younger brother nodded, "Yeah, our younger siblings. There are 5 of them."

"If you hurt them or even pick a hair out of their heads, I'm killing you on the spot!" Sanemi snapped and you hummed happily as you swayed your head from side to side, "No worries! I love kids!"

"We trust on that…"

The drive to their apartment complex was quiet… If they ignored how you seemed to think what was going in your mind out loud.

"Kids kids, cute and sweet!"

"Must protect!"

"I'm starting to think that guy at the Slave House screwed us over…" Sanemi grumbled as he and Genya listened to you hum by yourself like a… Like a crazy person.

"So?" Your eyes focused as you looked at the brothers, "Which battle earned you those scars?"

"Battle?" Genya wondered out loud and you nodded, "We Demons fight all the time, but if you don't kill you heal and won't scar."

That made sense. Sanemi growled as he glanced at you from the mirror, "We had our own fights. That's it."

He wasn't really in the mood to share how he and Genya were scarred, but you seemed to understand that he wanted to stay quiet about it. So you hummed, "Makes sense! But…"

"But what?"

"Humans are so resilient!" You grinned, "Your scars look cool! Wish I had some to show off my strength, but the bones of my opponents were all that I had!"

"We don't need to hear about that!" Sanemi snapped and you giggled a little as you looked out of the car's window, humming by yourself again.

When you made it to the Shinazugawa household, the eldest brothers called their siblings over and all 5 of them came when called.

"Kids, this is your new Demon!" Sanemi said and the kids were awed as they looked at you.

"My, and who are you, little angels?" You giggled as you looked at the kids who eyed you shyly and carefully. Genya smiled as he pointed at his younger siblings, "From eldest to youngest, Sanemi, me Genya, Teiko, Hiroshi, Sumi, Shuya, and Koto."

"Hello everyone," You smiled as you pointed at yourself, "I'll be your new nanny, your servant, your friend, your bodyguard, your-!"

"Are you our new family member?" Shuya asked and you blinked, a little stunned, before nodding happily, "Yeah! I can be anything you want me to be!"

"Remember kids, she is a Demon so you have to be careful also!" Sanemi said, but his younger siblings were all so impressed by you and curious about you.

"You're very pretty." Sumi smiled a little shyly as she looked at you and you grinned, showing off your sharp teeth.

"Aww, thank you, little angel!" You laughed as you bent down to the kids' eye level and held your pinky to them, "I pinky promise you guys that I will always keep you safe and sound! No one will harm you as long as I'm here!"

"You promise?" The kids asked and you waved your pinky finger at them, "I promise!"

"Jay!" The kids cheered as they rushed to see you better, giggling and laughing as they surrounded you. Meanwhile, Genya and Sanemi shared glances and nodded.

"She appears like a good purchase." Genya hummed thoughtfully, but his older brother frowned as he crossed his arms, "Time will tell."

"And if she isn't?"

"Then," Sanemi's face twisted with an angry scowl, "I'll take her out myself."

And that was his promise to Genya, their siblings, and you.
