At the Infinity Castle Daki was wondering why they were summoned

Daki: (Why did Lord Muzan summon us like this it can't be that someone out there actually managed to kill an Upper Rank)

She reached the center where everyone else was

Douma: My Daki what a pleasure seeing you here

Daki: Nice to see you, Douma

Douma: Oh I must say though I am quite worried I haven't seen my buddy Akaza it's not like him to be so late

Daki scoffed 

Daki: He really should learn to be punctual such inaccuracies are exactly why he must've been defeated by that brat I'd never let something like that happen to me

Douma said nothing he simply started shivering at the thought of that day he was nearly killed Daki noticed his silence 

Daki: Oh right come to think of it you were also nearly defeated by the girl of her same family weren't you

Douma said nothing he simply walked off seemingly ignoring Daki this action annoyed her but she let it go 

Time passed and soon Muzan and the other moons arrived he announce that Akaza was killed this news shocked everyone Douma was in tears but said nothing Muzan then raised the ranks of every Moon below 3 his fears only amplified so he gave the moons even more blood but just enough so that combined they were still nothing to him

Muzan: From now on I don't want anyone slacking off and whoever kills the Tsugikunis will be granted one request from me within reason, their deaths are priority number one

Douma: Even over the Blue Spider Lily and the Ubuyashiki family's whereabouts 

Muzan: Yes, they must be disposed of as soon as possible no matter what it takes, and don't be reckless take them seriously

Upper Moons: Understood

With that, the meeting ended and everyone was sent back to their original destinations

Muzan: (These damn Tsugikuni they're too strong as enemies I'd turn them into demons but after what happened to that girl that may only work to my disadvantage if they all became powerful demons they may surpass me and the moons they should be disposed of as soon as possible hopefully then I can stop feeling this fear)

Later in another place, it's morning Rimuro awoke in an unfamiliar bed

Rimuro: (Where am I)

He sat up straight on the bed and looked around when he looked to his left he saw Tanjiro and Nezuko both wearing blankets they were looking at him with tears in their eyes

Rimuro: Are you guys o-

Before he could finish they both embraced him and sobbed

Rimuro: Jeez calm down guys you'd think I was dead or something

Tanjiro looked up at his brother while he was hugging him

Tanjiro: You've been in asleep for 3 weeks

Rimuro: . . . Oh so that's why I feel like I could drink a sea and eat a whale

Nezuko: After the battle with Akaza you passed out the Kakushi came soon for the clean up but Rengoku insisted on carrying you the rest of the way himself 

Rimuro: I see where are we right now

Tanjiro: The Flower Mansion Ms. Shinobu offered to treat you personally she diagnosed that you pushed yourself past a limit and were exhausted it's a miracle that you were able to fight for as long as you did

Rimuro: I see I'll have to thank her later then

Rimuro looked at his nightstand and found various goods and notes

Rimuro: What's all this

Nezuko: The other Hashira and Demon Slayers came by to send get-well gifts and congratulations on being one of the first Hashira to defeat an Upper Rank

Rimuro: I see I'll have to give those a read

Rimuro's stomach rumbled

Tanjiro: I'll go get you some food brother

Nezuko: And I will get tea

Rimuro: You guys don't have to

They both raised their hands

Tanjiro and Nezuko: NO YOU ARE STILL RECOVERING YOU NEED TO REST BROTHER WE'LL TAKE CARE OF YOU SO STAY HERE

Before Rimuro could argue they both bolted out of the room

Rimuro: Well nice to know that they're alright in any case you can come out now 

Ciel: As expected of you to notice me, Master

Ciel then entered through the window

Rimuro: Hope you weren't too worried

Ciel: I knew you'd pull through it's you after all

Ciel sat on the bed on Rimuro's right

Ciel: Still that's a pretty dangerous move you've created you exhausted everything to use that many Breathing Styles

Rimuro: It's a necessary evil still this body does have a lot of sentimental value to me so I guess I should take care of it

Ciel: Still I was more worried about Master's mental state

Rimuro: . . .

Ciel: It must've been hard to let go but even harder to hear such words from them

Rimuro: It's not like anything said wasn't true I could've saved them I could've found another way for them to become Demon Slayers and Demons but I didn't instead I-

Ciel embraced Rimuro

Ciel: The fault isn't yours it's Muzan's he murdered them after all

Rimuro: . . .

Ciel: Don't blame yourself you knew what you needed to do to save countless lives if you regret it you can fix it not too much is above you

Rimuro blushed and avoided eye contact

Rimuro: W-w-well I guess your right 

Ciel: Good and don't let it bother you I'm positive not a single one of them would blame you

Rimuro: Ok

Ciel: And don't push yourself the whole point is for everyone to make it out in a better state that includes you

Rimuro: All right already no need to nag me I get it

Ciel: DO you

Rimuro: YES now will you let go 

Ciel: . . . No

Rimuro: What why

Ciel then pushed Rimuro down and got on top of him

Ciel: I think I deserve a reward for helping you out of your slumber is all

Rimuro: W-w-what why

Ciel: Me interfering like that in your mindscape is cheating I broke the rules for you which lead to you saving the individual known as Kyojuro Rengoku on time

Rimuro: . . . You just have an excuse for everything don't you

Ciel didn't answer as she got closer to his face

Rimuro put his finger on her lip

Rimuro: Look we can't at least not while demons are still active maybe after but not now

Ciel pouted

Ciel: And yet you were so eager to do it on mass in a dream

Rimuro avoided eye contact

Rimuro: Look ask me for something else just not this there's too much going on right now

Ciel paused for a bit but then she got off of her master

Ciel: I suppose that's fine there's only one other thing I could currently want then

Rimuro: And what's that

Ciel: I won't tell but you'll figure it out soon

Ciel disappeared from where she was standing Rimuro sighed as he looked over the notes and get well cards

Rimuro: (Nice of them to get me these deep down they're all good people all the more reason for me to save them all)

Rimuro was ordered to take some time off so that he could recover in that time he and his siblings decided to visit Kyojuro's home they walked to the front yard and saw a boy with a broom sweeping the outside

Rimuro: Hello you must be Kyojuro's younger brother that he spoke about Senjuro right

Senjuro: Yes I'm sorry but who are you

Rimuro: I'm Rimuro Tsugikuni and these are my younger siblings Tanjiro and Nezuko

Tanjiro: Hello

Nezuko: It's a pleasure to meet you

Senjuro: Oh forgive my lack of formalities Lord Rimuro

he said this and did a short bow

Rimuro: You don't need to be formal with me just call me Rimuro

Senjuro: Oh ok

Rimuro: Sorry to bother you guys but is Kyojuro here

Senjuro: Yes he's inside he just got back from a mission

Rimuro: Can we see him

Senjuro: Of course please come in

They followed him to what looked like a living room where they sat

Senjuro: I'll go get brother, wait here, please

Senjuro left and close the door

Tanjiro: What did you want to talk to Rengoku about

Rimuro: Nothing, in particular, I just wanted to visit him and thank him for carrying me back

???: WHO'S IN HERE MAKING ALL THAT RACKET

The trio turned to an open door and saw a man with a pot of sake tied to his wrist he had a similar color to Rengoku

Shinjuro: Just who the hell are you 3 ANSWER ME OR GET OFF MY PROPERTY

Rimuro: I'm Rimuro Tsugikuni and these are my siblings Tanjiro and Nezuko we're Demon Slayers we simply came to see Kyojuro is all

He looked at all of them but once paying attention to Tanjiro he dropped his sake

Shinjuro: You're what . . . I get it now that means YOU'RE SUN BREATHING USERS AREN'T YOU am I right

Rimuro: Yes we do use Sun Breathing what of it

Shinjuro dashed toward the 3 seemingly hostile they all dodged behind him

Tanjiro: Why are you acting so hostile like this

Shinjuro: Despicable you intend to mock us after everything we've been through

Rimuro: Dude calm down we didn't come here looking for trouble we just wanted to see our friend

Shinjuro: A Sun Breathing user would NEVER help people like us I know all about those earrings of yours it was in that book and that mark on your face

Nezuko: Wait you know about Great Grandfather Yoriichi

Rimuro: It makes sense the Flame Hashira of our Yoriichi's time was his good friend he must've written about him in his journal

Shinjuro then went on about Sun Breathing being the first and most powerful technique and that everything else was a cheap imitation 

Shinjuro: Don't get cocky just because your Sun Breathing users 

Rimuro: You're wrong

Shinjuro: Eh 

Rimuro: Not a single one of the Breathing Styles are worthless each one of them are used to save lives Sun Breathing may be more advanced and powerful than the others but if our grandfather thought they weren't necessarily that they were just as worthless as you say he wouldn't have bothered to create them so that his allies could fight alongside him anyone who can master a breathing style has their own talent it's not just Sun Breathing 

Shinjuro growled at Rimuro's statement

Shinjuro: Why you little BRAT

Kyojuro: FATHER, PLEASE CEASE THIS

Everyone looked to see Kyojuro standing at an open door with Senjuro

Rimuro: Sorry Kyojuro didn't mean to cause trouble

Shinjuro growled as he left the room without a word

Nezuko: Where's he going

Senjuro: Probably to get more sake

Kyojuro: You'll have to forgive him ever since our mother's death he's been like this

Rimuro: As someone who knows loss I understand it's fine really I just came to talk with you and give you my thanks for carrying me the whole way

Kyojuro: Think nothing of it you were the main reason we were able to defeat him it was the least I could do

Kyojuro and Senjuro sat down they spoke with each other about various things from favorite foods to hilarious memories this carried on until evening and they decided it was time to go Kyojuro saw them out

Kyojuro: Rimuro one more thing

Rimuro turned back to face a bowing Kyojuro

Kyojuro: Forgive me for not being able to do more I should've helped you more in that battle

Rimuro: We all did our best in that fight but no one died so it's all good we should all just be grateful to be alive so don't let it bother you too much

Kyojuro: WISE WORDS RIMURO FEAR NOT I WILL TRAIN MYSELF TO BECOME EVEN STRONGER SO I MAY BE ABLE TO FIGHT ON EQUAL GROUND AS YOU

Rimuro: I'm looking forward to it

Kyojuro: Oh and as for your sister she did a splendid job protecting all the passengers and helping us leave our dreams I do not doubt that she can fight along Demon Slayers

All 3 of the Tsugikuni gave him a wide smile

Rimuro: Thank you Kyojuro that means a lot

Tanjiro: We'll do what we can to convince the other Hashira too

Rimuro left the Flame Mansion time passed Rimuro continued to train Zenitsu and Inosuke and they were making even more progress despite the bumps in the road they even each went on solo missions 

Zenitsu: I'll go and never complain if you just let me bring a lock of Nezuko's hair with me

Rimuro: You're lucky I still let you breathe the same air as her NOW GO AND IF I HEAR YOU MAKING EVEN MORE OF A FOOL OF YOURSELF OUT THERE I'M GIVING YOU TOUGHER TRAINING

Zenitsu: SO HEARTLESS

Inosuke: Watch I'll kill that demon by myself and get even stronger from it

Tanjiro: That's great Inosuke I'm sure you can do it 

Inosuke: OF COURSE I WILL 

Even more, time passed once Rimuro recovered he started going on missions until he was on his way back to the Flower Mansion

Rimuro: (Good thing the Kakushi told me that my Mansion should be finished soon that means I can sleep peacefully without having to worry about Ciel sneaking in my room AGAIN I get she missed me but that doesn't mean she needs to watch me sleep or when she tries to get in bed with me it's becoming harder and harder to resist her DAMN HUMAN HORMONES)

Aoi: LET ME GO AT ONCE

Rimuro: (Oh is that today forgot to keep track)

Rimuro overheard all the arguing and knew what it was immediately

Tengen: HEY CUT IT OUT GET OFF ME YOU BRATS

Rimuro: UZUI

Tengen: (Oh great) Hey Rimuro

Rimuro: . . . Uzui what are you doing and please tell me it's not what it looks like

Kiyo: HE'S KIDNAPPING THOSE GIRLS PLEASE HURRY AND RESCUE THEM MISTER RIMURO

Tengen: Why you, SHUT YOUR MOUTH

In a flash the girls were all back at the doorstep of the Mansion Rimuro was holding Naho on his head and Aoi in his arms she blushed at being carried 

Tengen: (He's so fast I had little time to react)

Rimuro: Tengen I'm sorry but no matter how I look at it this looks bad so for your sake please explain before I have to tell Shinobu

Tengen: Now now calm down let's not do anything too crazy

Rimuro: This coming from the guy that's kidnapping little girls

Tengen: LISTEN I WAS TAKING THOSE 2 BECAUSE I NEED FEMALE CORPS MEMBERS FOR A MISSION AND I DON'T NEED PERMISSION TO TAKE ANYONE WHO'S NOT A TSUGUKO

Rimuro: And I thought Gyomei was the blind one look at the girl you were about to take that's on my head can't you see she's not even a member of the corps I doubt she's even in her double digits

Tengen took a good look at her

Tengen: . . . Oh yeah never mind then

Rimuro: . . . Look how about I and my Tsuguko go with you instead

Tengen: Your Tsuguko?

Tanjiro, Nezuko, Zenitsu, and Inosuke jumped from the bushes as well

Rimuro: These are my comrades and don't look down on them for a second I've put them through such hellish training it makes Hell look like a campfire they will accompany us

Tengen thought it over for a bit

Tengen: Well I suppose it could be worse but if you're coming with me on this mission then know that I'm in charge

Rimuro: Fine just don't get a big head about it

???: Oh if it's women you need then I'll happily volunteer

Everyone looked to the entrance and saw Ciel standing there nonchalantly

Tengen: Sure if you want but my rule still stands

Rimuro: I'm sorry will you all give us a minute

Rimuro said this while dragging Ciel by her wrist out of earshot

Rimuro: What are you doing

Ciel: I already told you darling I'm coming with you both

Rimuro: Ok but why though

Ciel: Because we haven't been able to spend much time together since becoming Hashira and I want to change that

Rimuro: Isn't 3 Hashira a crowd 

Ciel: Oh are you saying you'd prefer it be just the 2 of us I'm fine with that

Rimuro: You know that's not what I meant, things will be too easy if there are 3 Hashira

Ciel: Tough because this is what I want as my reward

Rimuro: So you're cashing it in

Ciel nodded

Rimuro sighed 

Rimuro: Fine just try to focus on the task at hand

Ciel: Of course I know don't forget I am the Nature Hashira after all

Rimuro: Yeah I know 

Ciel: Good then let's go

Ciel skipped away

Rimuro: This is gonna be a long arc















Shout out to my fellow writer AndrsFernando1 their birthday has arrived they make great stories lots of them are even better than mine so just send him some support on this good day he's my inspiration after all




























I'll be doing the Taisho Era secret first this time here's what all of Rimuro's get-well cards said

Kanae and Shinobu: Get some rest and don't push yourself too hard

Tengen: I hope your recovery is as flashy as your victory

Mitsuri: Congratulations on your victory continue to do your best ok

Gyomei: I pray you may have a swift recovery 

Rengoku: IT WAS A PLEASURE FIGHTING ALONGSIDE YOU PLEASE GET REST AND GET WELL SOON

Obanai: Don't get cocky because of your victory you better keep working harder

Sanemi: Don't get comfortable I'll catch up to you soon brat

Giyuu: Good job

Muichiro turned in a blank piece of paper












































































For the last time Ciel NO

Ciel: But hear my argument

No matter how many times you ask I'm not going to put this story on hold to write One-Shot Lemons of you and Rimuru

Ciel: I see no reason why not it'll most likely do amazing

Look I've got memes to post now quit it before I nerf you to Great Sage

Ciel: This isn't over

Yes it is

Ciel: Of course, it isn't bringing it up now means that the idea is in the public's heads and then I won't be the only one asking

Wow Rimuru was right you are annoyingly clever

Ciel: It's my job

But surely you're also clever enough to know that Rimuru's computer password is Shizuebestgirl with some numbers

Ciel's eyes became empty the words cut through her like a knife she then fell to her knees and hands

Now that that's out of the way please enjoy the memes




Rimuru: You're a Puppeteer Clayman everything special about you came from someone else

Rimuru: Don't worry it scares me too

Rimuruism is for the people

I don't know why they feel the need to complicate it it's literally that simple

Unless it comes to some random debate about power scaling that is

Found these while searching for memes and I love them so I challenge you guys to make good interaction lines like this one for Isekai/Fantasy characters they can be anything from pre-battle banter, mid-battle banter, after-battle banter, victory banter, loss banter, or even just normal conversations and meetings the one I like best before the next chapter is posted gets a special prize of adding something within reason to the story you can post as many as you like in the comments good luck and thanks for reading
