~Sanemi

•first meets you in the village

•He was grabbing Ohagi when he saw a person in a hoodie, which was weird

•He saw you grabbing Ketchup, and gulping it down like it was nothing

•Honestly was disgusted when he saw you do it, it was strange

•He began wondering why you were wearing a hoodie, and why you covered pretty much everthing of your body

•After a minute he figured you were a demon, so he was about to take out his sword, when you disappeared

•He looked around, after that he figured you had teleportation blood art

•he came back the next day, and there you were

•you kept drinking Ketchup, but were secretly aware of who he was, and what he was apart of

•You can see peoples past, it’s just one of your abilities to judge people

•You found yourself and Sanemi quite Similar

•You both killed your friends/ for him, family, to protect someone

•You both have little brothers who happen to be taller than you, even if yours is a ghost now

•and you both want to defeat the number one threat, which is why you were quite interested in him

•Once you left the building, he followed you

•You didn’t really mind at first, it reminded you of a Dog coming to it’s owner

•However, you realized he was starting to follow you to your home

•You didn’t want him there at all. The bodies are still there

•You ran because you didn’t want him to find out

•Though you were really lazy, so you just decided to go to 1/100 of your speed

•He chased after you once you did, though he could tell this wasn’t even close to your fastest run, even though he could barely keep up

•He followed you to a Village, a Village he never even knew existed

•You turned around, he had already hid

•You sighed and just walked inside your house, it was a busy day doing your ‘work’

•Sanemi let you go in first, after a minute he came in after you

•Sanemi looked around at blood stains on the walls, there was also Dust

•Sanemi began walking around, confused as ever

•Sanemi then confirmed his thought of you being a demon, but a whole village?

•Was there a chance you would be an Lower/Uppermoon then?

•”No…”

•He thought

•”She can’t be an Uppermoon/Lowermoon, she would have a mark then”

•He thought again

•He began looking over the house for you, the first place he checked was the living room

•There he found you, sound asleep on a couch

•It was weird

•It was almost night, but you were asleep at night instead of day

•He ripped your hoodie off your head, and thats when he saw your real face

•He didn’t expect you to look human, since he figured you were a demon

•You were pretty much human, but the things you did were inhuman

•He rolled his eyes, but then something caught him

•It was a sharp, silver thing

•He moved closer, and saw a knife

•A knife covered with Blood and dust

•Sanemi attempted to grab it, but before he could

•*yank*

•Sanemi looked up to see you awake

•You chuckled darkly before getting up

•”Wow~ you really thought I went to sleep?”

•You just darkly chuckled before smirking

•”I was aware you were here, just because it looks like I’m asleep….. D o e s n ‘ t m e a n I a m”

•He took out his sword and tried to stab you, but you dodged

•You stood up and smiled creepily

•”Thats not very nice of you Shinazugawa…yet when were you nice? When you were a child?”

•Sanemi got confused on how you knew his name, in which you laughed

•”Wow….*bursts out laughing* T-Thats a good one, Bro!”

•You laughed

•He tilted his head, there was no one there

•He growled

•”Who the hell are you talking to?!?!”

•He asked

•You shrugged but kept your smirk

•”Isn’t it obvious? I’m talking to my brother”

•He growled

•”Theres no one there!”

•”He is there!”

•You decided you were too lazy to deal with him, so you just left the room

•He chased after you

•You smiled lazily as he attempted to stab you with his sword

•Ofc you dodged

•”Jeez, you actually expect me to take it? Your stupider than I thought”

•Sanemi growled and tried to stab you again

•You dodged

•You yawned just to make him a little frustrated

•”Seriously, I don’t have time for your shit, I-“

•”Let me guess, kill innocent people!”

•You groaned

•”No, I did that this morning, stupid, whats on my schedule now is to sleep, now go”

•You didn’t really care that now he knew you were a mass murderer, you just wanted to go to sleep

•He attempted to attack you, but you dodged his attack

•”Jeez, get better aim”

•You walked upstairs, you never really slept in your bed, but you figured you would sleep on the couch once he gave up and left

•You honestly didn’t want to kill him, but honestly when did you want to kill someone?

•If you had to be completely honest, you never knew when or where you wanted to murder, you just wanted to gain more power to defeat him….

•You wanted to leave Sanemi be, though it was very tempting to kill him and get his wind breathing, you had never killed a wind breather before

•Sanemi got mad and started attacking furiously

•You dodged with ease, though getting tired since you did get tired often

•You just ran to your room and slammed the door

•Sanemi kicked down the door, to see you nowhere

•He grunted and left

•However once he got downstairs he saw you on the couch, sound asleep

•Sanemi thought about what to do for once, before deciding to leave and kill you tomorrow

•He didn’t see you tomorrow, because you had gone to another village to kill down, ofc you succeeded in getting everyone

•However, the next day he found you getting your ‘daily ketchup’ as you would call it

•he chased after you once you left

•He grabbed your shoulder

•You didn’t turn around, but instead pried it off and ran off

•He ran after you

•He lost you after 5 minutes of chasing you

•Sanemi groaned but just heads back to his estate

•You just go to find another village to kill

•You guys see each other every once in a while

•You only run away when he tries to kill you

•Sanemi had never actually seen you kill, he was just assuming since he saw blood in your house

•After seeing him so many times, you developed a crush on him

•You rejected this fact so many times only because you knew it was wrong

•How was it wrong? You only had 3 reasons

•One, he’s a hashira and your a mass murderer

•Second, You might hurt your dead brothers feelings, since he follows you around as a ghost

•You think it might hurt his feelings because you loved him and you killed him, but you won’t kill Sanemi even though he’s not a relative

•The last reason was because you knew he would die

•You knew one day, you would kill him

•Then your emotions wouldn’t even matter anymore

•After all, thats everything you were, a killer who’s only been a killer

•Besides, he’s tried to kill you before so how in the heck would he be attracted to you?

•However, you were wrong

•Despite him thinking you were a murderer, he couldn’t help it

•He found you attractive, strong, and intelligent

•He kept telling himself he shouldn’t feel this way for a serial killer, but he couldn’t help it

•One day, while he was hit to a tree in a fight with a demon, you showed up and stole it

•However, you didn’t notice him

•He was about to yell at you, when you said something he didn’t expect

•”…Brother….It’s almost ready, I’m almost done collecting them, then, I’ll put an end to him”

•”I cannot wait until he is exposed, but sometimes…I feel as if I crossed the line…”

•Sanemi then saw a flying piece of cloth then it fell upon your shoulders

•He saw you smiling a few seconds after

•”….thanks bro, needed that, but I can’t just give up my spree now! Until he is dead, I can never give up!”

•”I will kill the demon king who has wronged us a thousand times!”

•Then you left in what must have been a millisecond

•When you said you wanted to kill the demon king, that changed his whole perspective of you

•When you started taking over his kills, you started to notice that he didn’t care and just walked away instead of trying to kill you

•One day, when you were getting your daily ketchup, he grabbed your arm, in which you turned around

•”What?” you just asked him

•”Why?”

•You shrugged

•”Why what?”

•”Why didn’t you tell me you just wanted to kill him?!”

•”……”

•Your face was bland, though on the inside this was the first time your blood froze like this

•You didn’t respond

•After seeing him getting impatient, you sighed

•You decided to act natural

•”…Because who would understand?”

•Was all you said

•”I would.”

•You rolled your eyes

•”Yeah right, I admit, you’ve been through some harsh pain, but it’s not as big as mine, so move along.”

•Sanemi growled, though he still didn’t know how you knew his past

•Your smirk started to fade, so you looked down

•Sanemi sighed

•”Sometimes I wonder how I fell for you…”

•”Excuse me?”

•Sanemi barely realized what he had said

•”I-uh-well…I uh….”

•You honestly knew what he meant

•Just because you wanted to be the ‘dominant’ one, you decided to confess before he got a chance

•”Hey, it’s fine, love you to”

•Sanemi turned red

•You just smirked and laughed

•”Hey, that doesn’t mean your gonna pay less attention to me, right?”

•You heard your Ghost brother say

•You turned to him

•”Of course Bro, I love you more than anything, your my brother after all”

•Sanemi sighed

•”I think I need to get you a therapist though”

•”No, no you don’t”

-What dating him was like

•Once dating him, despite you missing it, you decided to mostly kill demons instead of mostly killing humans

•Though every once in a while, you kill a whole half of a village, like, once a month

•Sanemi’s glad that you kinda stopped killing humans, but whenever you do he yells at you and ignores you for 20 hours

•It’s 20 hours because you threaten to kill someone else if he doesn’t pay attention to you

•He sometimes gets mad at you just because you fulfill the dominant role more than he does

•It’s a switch-top/bottom thing for you guys, but you do top more often

•He acts like a Tsudere, which you find adorable

•When you first saw his Dog, you almost had a meltdown because it was white like a Dog named ‘Temmie’

•You actually killed your Dog as well

•Sanemi sighed

•”Really? You have to kill animals as well?”

•”Yes.”

•Sanemi soon learned why you killed demons along with humans

•It was because if you killed someone, you could gain there abilities as well

•He found that amazing and strong, but at the same time dangerous

•He was wondering if that could make you the number one target for Muzan

•You honestly couldn’t care less about Muzan killing you

•You were more furious with the idea of Muzan killing Sanemi

•You believed that if Sanemi should die, it should be by your hands, just like your family

•Sanemi still finds it weird why you don’t eat food, but instead drinks ketchup

•One time, he gave you Ohagi to eat but you poured a whole entire bottle of Ketchup on it only because you said it would ‘spice’ things up

•Sanemi also learned that despite your villainy murders and your creepy plots and personality, that you have a ‘funny’ side

•You enjoyed telling bad puns, knock knock jokes, and loved pulling pranks

•You especially loved pulling ‘sike!’ Pranks on Sanemi, you love seeing his reactions

•You also like looking to the side of him and gasping and looking shocked

•Then you would say “Demon king!” With a strong anger sense

•When he would look over, you would burst out laughing

•”Made ya look~~!”

•Sanemi gets extremely mad at you, but only for 2 minutes before you calm him down

•Sanemi also got a good relationship with your brother

•He first confirmed that he was real when you told your brother to smack him

•It hurt really bad

•Sanemi can somewhat have conversations with him, only when your around

•He just takes out a piece of paper and they just write stuff to each other

-Meeting his brother

•You first met his Brother inside his estate

•You could tell immediately that he was his brother

•You talked to him for a bit

•He was enjoyable to talk with, even if it was for a little bit

•You approached Sanemi about it

•He was very angry that you had a conversation with his brother

•He denied over and over again about how he ‘didn’t’ have a brother

•”Your really bad at lying”

•”I am not lying!”

•Soon Genya found out you were dating his brother, in which he was a little confused at first

•You joke around/Tell puns/play pranks on/with Genya

•You would sometimes ask Genya to help you prank Sanemi, in which he would refuse

•You understood, after all, Genya believed Sanemi hates him

•When Genya would refuse, you would hear your brother say

•”At least he doesn’t like pranks/jokes”

•You then would roll your eyes and say

•”Oh I know Bro, you love those puns, don’t ya? They just get you so ghostly”

•You laughed at your own pun

•Your Brother would then tell you to stop saying those annoying puns

•Genya would be left confused

•’….Aniki sure has a weird Gf/Bf’

•You would try to get them to get along, after all, you know what it’s like to loose someone without even apologizing

-extra

•You never did meet the Hashira, because lets be honest, them, meeting a serial killer? Yeah that wouldn’t end well

•Especially since you date the wind Hashira

•If anyone EVER said anything behind Sanemi’s back, you would kill them, you didn’t care if anyone saw or not

~Thats it
