Recap.

Shinazugawa stabbed Nezuko through the box again which made Y/n fight his killing intent.

Tanjiro: Stop it!

Shinazugawa: Come on out, demon! It's the human blood you love so much!

Nezuko came out of the box with slit pupils and drooling.

Y/n: (Thinking: Come on, Nezuko. Don't take his blood.)

Nezuko was looking intensely at Shinazugawa's blood.

Shinazugawa: What's the matter? Go on! You know you want it.

Iguro planted his elbow deeper into Tanjiro's back while Y/n was still at the end of Uzui's swords.

Shinobu: Iguro, you're being too rough. Ease up a bit, will you?

Iguro: I'm only doing this because he's trying to escape.

Shinobu: Tanjiro, if you use any breathing techniques while your lungs are squeezed, it'll force your veins to burst.

Uzui: His vains will burst!? I like it! Sounds dramatic! Come on, show me!

Y/n: Don't forget about me, Master Uzui.

Uzui: From where I stand, you look to be at my mercy.

Y/n: I'd look a little closer if I were you.

Uzui looked at his chest and saw Y/n was holding a sword to his heart.

Uzui: (Thinking: What?! He was able to get a blade this close to me without me realizing?!)

Y/n: (Whispering: I know you can hear me at this volume. If you make any sudden moves, it'll end badly for both us.)

Uzui silently growled in anger.

Y/n: (Thinking: Come on, Nezuko. You can do it.)

Tanjiro began to scream loudly.

Shinobu: Tanjiro!

Tanjiro broke free from his ropes as Iguro got his arm grabbed by Y/n who pulled Iguro's arm off Tanjiro.

Uzui: What the- (sees Y/n's not at his blades anymore) Y/n!

Iguro: L/n, how did you even get free?!

Y/n: I am just that goddamn good.

Tanjiro ran to the porch.

Tanjiro: Nezuko!

Nezuko began to think about memories of her family and heard Urokodaki's voice.

Urokodaki: I convinced her that all humans are her family. I told her to protect them.

She then imagined Tanjiro and Y/n in front of her.

Nezuko: Humans are to be protected and saved. Never hurt them. I will never hurt them.

Back in reality.

Nezuko turned her head away in disgust to Shinazugawa's shock.

Master: Tell me what happened.

Twin 1: The Demon girl turned her head away in disgust. Despite Shinazugawa stabbing her three times, and then flaunting his bloody arm in front of her face, she restrained herself from biting him.

Master: There it is, undeniable proof that Nezuko won't attack humans.

Y/n: If I may speak, does that mean this test is all over.

Master: It does.

Y/n: Good.

Y/n let go of Iguro's arm.

Y/n: Take a good look at that and think about it before you sleep tonight, Master Iguro.

Y/n patted his head.

Iguro: Don't touch me, brat.

Master: Tanjiro. I'm sure that even after this there are some who cannot accept Nezuko. Work towards changing their minds. Prove to them that you and Nezuko can be helpful to our cause, by fighting as Demon Slayers.

Iguro: Hang on, we still don't have anything that'll confirm L/n here will kill anyone or not.

Tanjiro: Please, I promise I'll keep him out of trouble!

Shinazugawa: And you really think you'll be able to?

Iguro: We couldn't even do it. I won't believe someone like you will be able to.

Y/n: Care to run that by Tanjiro again, damn snake.

Y/n drew Eleatara.

Tanjiro: Y/n, stop it.

Y/n: What? But Tanjiro...

Tanjiro: I said stop!

(A/n: Ignore Hashirama and Tobirama's lines)

Y/n sheathed his blade and got on his hands and knees.

Y/n: All of you, I apologize for my disrespect and I accept any punishment you see fit.

Everyone looked at Y/n in shock.

Iguro: (Thinking: That boy really can control L/n.)

Master: Well, there we have it. Like Y/n did, go out and defeat a Twelve Kizuki. Do that and you will be accepted by all. Your words will carry more weight as a result.

Tanjiro: All right... Y/n, my sister and I will defeat Kibutsuji! Rest assured, we will strike him down and stop this endless cycle of misery!

Master: That is a bit ambitious for you three. Let's start by defeating a Twelve Kizuki first.

Tanjiro's face turned red.

Tanjiro: Yes, sir.

Y/n slightly shook his head with a small smile.

Y/n: Oh, Tanjiro.

Mitsuri held in her laughter.

Mitsuri: (Thinking: You mustn't laugh, Mitsuri! Keep it together!)

Master: It goes without saying that the Hashira of the Demon Slayer Corps have phenomenal skill. They have trained themselves to the brink of death and have defeated it, as well as those of the Twelve Kizuki. That is why the Hashira receive respect and favorable treatment. So it would be best for you to mind your manners when addressing them, Tanjiro.

Tanjiro: Yes, sir!

Master: That means you too, Y/n. Please, do better to mind your manners in the presence of your superiors.

Y/n: As you wish, Master.

Master: Also. Sanemi... Obanai... Don't torment the younger ones too much.

Iguro: As you wish.

Shinazugawa bowed as Nezuko gave him an angry look.

Shinazugawa: As you wish.

Master: We have concluded our business with you and Y/n, Tanjiro. You both may step back.

Shinobu put up her hand.

Shinobu: If that's the case, Master. Allow me to take them into my abode.

She clapped her hands.

Shinobu: All right, then! Take them away please!

Y/n: I'll take Tanjiro. You, male Kakushi, please grab the rest of my mask.

Male Kakushi: Yes, Master Y/n.

The Kakushi bowed in respect to the Master and Hashira before he grabbed Y/n's broken mask.

Y/n: All right, Tanjiro, let's go.

Tanjiro: Wait, what about the-

Y/n: Don't worry. I'll get him later.

Y/n put Tanjiro on his back as the female Kakushi grabbed Nezuko's box and put it on her back.

Master: Tanjiro, give Tamayo my regards.

Tanjiro's eyes widened.

Master: And Y/n, please come back here later tonight to give a report.

Y/n: Yes, sir.

Y/n with Tanjiro on his back left with the Kakushi.

Tanjiro: Hold on a second! Did I just hear him mention Miss Tamayo?!

Y/n: Yeah.

Male Kakushi: Who is that?

Y/n: Let's just say, she's a trusted friend of the Corps. Now, who are you two exactly?

Male Kakushi: My name is Goto, Master Y/n.

Female Kakushi: And I'm Himari.

Y/n: Nice to meet you both.

Tanjiro: So, not to be rude or disrespectful, but the Master-

Y/n: Looked sick? Yeah, it's an illness his family goes through. I don't remember all the details, but it has no cure and unfortunately gets worse the older he gets.

Tanjiro: How old is he now?

Y/n: I... don't remember.

Goto: He is 23 this year.

Y/n: Thank you, Goto. He's not the first Master though, his name is Kagaya Ubuyashiki. The Demon Slayer Corps has always been lead the Ubuyashiki family.

Himari: With all do respect, Master Y/n, are you sure you should be telling him all this?

Y/n: He's a member of the Corps, he has every right to know.

Tanjiro: So, the HQ seems to be pretty well hidden.

Y/n: That's because of the incident that happened roughly 500 years ago.

Tanjiro: What happened?

Y/n: I'm not clear on all the details, but what I do know is that a Demon Slayer that betrayed us and became a demon killed the then leader of the Demon Slayer Corps.

Tanjiro: That's horrible.

Y/n: Ever since then, the location of headquarters has to be kept a secret.

Tanjiro: Okay. What about the Hashira? What are they like.

Y/n: There are some that I know better than others. Like I know Shinazugawa and Shinobu pretty well, but I don't know much about Iguro or Tomioka. Though, I'm sure there was one more Hashira. Goto, what happened to the Flower Hashira, Kanae Kocho?

Goto: We unfortunately lost her a few months after you left, Master Y/n.

Y/n: I see.

Y/n looked down in sadness.

Tanjiro: Hey, let's change the subject. So, where exactly are we going?

Y/n: It's a place called...

Later.

They were in front a bigger Mansion.

Y/n: The Butterfly Mansion.

They stepped inside the front door.

Himari: Hello! Anyone home?

No one responded.

Himari: Is there anyone here?

Y/n: If no one answered the first time, what makes you think they're gonna answer the second time?

Himari: Let's go check out the yard.

They all stepped out and walked to the backyard.

Goto: Master Y/n, are you sure you can handle carrying your friend?

Tanjiro: Sorry about this, Y/n, but my whole body is aching up a storm.

Y/n: It's fine. I can handle it.

Tanjiro looked up at the Mansion.

Tanjiro: I thought the headquarters were big, but this mansion's in a league of its own, huh?

They saw butterflies as they got closer.

Y/n: This place didn't get its name for nothing.

They got to the garden and saw Kanao surrounded by butterflies.

Goto: Well, would you look at that. There is someone here.

Himari: That would be, um...

Y/n: Tsuguko Kanao Tsuyuri.

Tanjiro: A Tsuguko?

Goto: From what I was told, she stopped you real good last night. And later, Master Y/n pinned her to a tree with two swords.

Tanjiro: Okay, and that's something me and him are going to talk about later.

Y/n: Can you not talk about me as if I'm not standing right here?

Tanjiro: Right, sorry.

Goto: A Tsuguko is a swordsman trained by a Hashira. Only those with impressive skill are chosen.

Y/n: Yeah. Not to brag, but I was also a Tsuguko.

Tanjiro: To the Wind Hashira, right?

Y/n: That is correct.

Goto: One of the reasons why Master Y/n has a great amount of respect around here is because he was brave enough to be Master Shinazugawa's first and only Tsuguko.

Himari approached Kanao.

Himari: Please forgive us, Lady Tsuyuri. We were ordered to come here by Lady Kocho. Permission to enter the Mansion, ma'am.

Y/n: Don't bother, Himari. Ask her all you want, you're not getting a response.

Kanao looked at Y/n and dropped her small smile, but still didn't respond. Then Y/n felt a presence behind him.

Y/n: (Thinking: Who is this? It feels familiar.)

A voice shouted from behind.

???: Who are all of you?

Everyone except Y/n and Kanao jumped and turned to face a girl.

Goto: We are here on behalf of...

Himari: Lady Kocho!

Girl: That boy on the other one is injured, correct? You two are the Kakushi. And wait...

She looked closer at Y/n's face.

Y/n: If you're checking for scratches or bruises, you won't find any.

The girl pointed at him.

Girl: You!!!

She started shaking Y/n violently.

Girl: How dare you show your face around here after what you did?!

Y/n: Take it easy, my friend is on my back.

The girl go.

Y/n: Okay, now who are you?

Girl: What?! You seriously don't remember me?!

Y/n: Should I remember you?

Girl: We've known each other since we were kids and lived here together for two years! How could you not?!

Y/n: Hmm. Give me a name.

Girl: Does the name Aoi Kanzaki ring a bell?!

Y/n: Well, there was a girl with that name that I liked and... That's you, isn't it?

Aoi: It is. (sigh) Follow me.

They followed Aoi in, but Tanjiro took one last look at Kanao.

Y/n: Like what you see in her.

Tanjiro: What?

Y/n: Oh, nothing.

Inside.

Zenitsu was in a hospital uniform and laying in a bed screaming with a little girl wearing two red butterfly hair pin next to his bed.

Zenitsu: Five times?! I've got to take this five times a day?! And I have to keep taking it for three months?! It's such a horribly, bitter taste, too! I'm not gonna wanna eat a single thing after taking that! You're telling me that my arms and legs will be restored just by taking this medicine?!

Little girl: Would you please stop shouting?

Zenitsu: I don't understand at all!

Aoi, Goto, Y/n and Tanjiro were right outside the door.

Aoi: Still making a fuss, even now.

Y/n: Stop your whining. I've dealt with this for almost a week and you don't see me complaining.

Tanjiro: Zenitsu!

Y/n: We'll be going in. Goto, you're excused.

Goto: Before I go, here's your mask.

Goto gave Y/n the two pieces of his mask.

Y/n: Thank you.

Y/n and Aoi walked in Tanjiro still on Y/n's back and Zenitsu still screaming.

Aoi: Please lower your voice! How many times have we explained it to you now? If you don't stop this we'll have to restrain you!

That's when Y/n noticed the medicine bag.

Y/n: "For Zenitsu Agatsuma. Take 5 times daily." What happened to him?

Little girl: He got his limbs shrunk. That medicine will help them grow back to normal, but he won't stop complaining about it.

Zenitsu was a nervous wreck.

Tanjiro: Zenitsu!

Zenitsu screamed and hit in his pillow.

Tanjiro: What happened? Are you all right?

Y/n: Tanjiro, did you not hear what this little girl just said?

Little girl: I have a name.

Y/n: I'll ask for it later.

Tanjiro: So, you came up the mountain after all!

Y/n: Never thought you'd grow a pair.

Zenitsu looked up at Tanjiro.

Zenitsu: Tanjiro. Ahh! It was terrible, Tanjiro! Just awful! I got bit by the icky spider, and it really hurt! That blue girl's been yelling at me ever since I arrived at this place also! I hate my life!

Y/n looked at the bed next to Zenitsu and saw Inosuke was there looking sad.

Y/n: Hey, Inosuke. You're here, too.

Tanjiro: Oh, Inosuke! I'm glad you're safe! I'm sorry, I couldn't rescue you!

Inosuke: (Quietly: It's okay. Don't worry about it.)

Tanjiro: You're voice. Is that really you?

Zenitsu: I heard he mangled his throat or something. I don't know all the details, but I heard he got hit in the neck, and when he yelled at the top of his lungs sometime after, that's what pushed him over the edge. And it really messed up as you can hear. The whole thing is taking the wind out of his sails and made him really passive, you know it's kind of funny.

Zenitsu began to giggle.

Y/n: Yes, I'm sure it's almost as funny as getting your limbs shrunk by a little spider.

Zenitsu stopped laughing and looked at Y/n.

Zenitsu: Hey, Tanjiro. Who's the new guy?

Y/n: Seriously? Do I really look at that different without my mask?

Zenitsu: Y/n, is that you?!

Y/n: Yep. I can understand you being surprised, since you've never seen me without my mask.

Y/n laid Tanjiro on an empty bed and walked over to Inosuke.

Y/n: Sorry, Inosuke. I know I promised you a spar after our mission, but it looks like you're going to be here for a little while.

Inosuke: (Quietly: That's okay. I doubt I would have been much of fight anyway. I couldn't even handle a henchman demon.)

Y/n: You were just caught off guard, it could have happened to anyone, even me. The important part is that you're still alive. I know you can bounce back from this.

Zenitsu: Ah! Wait, did I take my morning medicine!?

Y/n chopping Zenitsu in the back of the neck, knocking him out.

Y/n: Be quiet. I don't usually like doing things this way, but I'll make an exception for you.

Inosuke was quietly snoring, indicating he was asleep.

Tanjiro: They're alive.

Himari was at the door.

Himari: Sorry for getting sidetracked. Here's the box.

She gently laid down Nezuko's box near the door.

Y/n Thank you, Himari. You are excused now.

She nodded and left.

Later.

The sun was setting as Y/n and Tanjiro took Nezuko's box to a small room with one bed and a single window that Tanjiro closed the curtains.

Y/n: All right, Nezuko. It should be good for you to come out.

Tanjiro: They said it was fine for you to use this room.

Tanjiro sat on the bed in pain.

Tanjiro: Ouch, ouch, ouch!

Nezuko got out of her box and stood next to Y/n.

Tanjiro: That whole encounter up on the mountain was really brutal. I got to be honest, everything hurts right now. Nezuko, what you did, protecting me on the mountain, thank you. And thank you Y/n for coming in to save us. There are the others, too. Tomioka, Urokodaki, they've all gone out and risked their lives on our behalf. It's really something, huh?

Y/n sat next to Tanjiro.

Y/n: Honestly, I'd say that you're all making a mistake risking your lives for me.

Tanjiro: What?

Y/n: Tanjiro, when I became this thing, the first thing I did was expose myself to sunlight hoping it would kill me, but it didn't. When a became half demon, I wanted to die. I didn't deserve the Butterfly Mansion, I didn't deserve the Hashira, I don't even deserve you two. If I wasn't such a coward, I would've cut my head off the second I realized sunlight couldn't kill me, but I didn't. I'll gladly do it for you two, but I don't want either of you to kill yourselves for trash like me.

Y/n felt something pinch his legs, he looked down to see it was Nezuko.

Y/n: The hell are you doing?

Nezuko: (angry) Mmm! Mhm!

Y/n: I don't understand what you're saying, but I can tell you're not too happy with me.

Tanjiro: Neither am I! Y/n, you are not trash! You are one of, if not, our most important friend! You've stood up for us, help us on several occasions! Sure, I don't approve of your outbursts, I know there's mostly good in you no matter what you say!

Y/n was still looking down.

Tanjiro: Tell me. When we were on the mountain, you said I was like your brother, right?

Y/n: Yeah.

Tanjiro: Well, if you really feel that way you, should know that brothers look out for each other!

Tanjiro placed a hand on Y/n's shoulder.

Tanjiro: If you're willing to cut your head off for us, then I'm willing to slice my stomach a thousand times over for you.

Y/n: But I can't ask...

Nezuko grew to her full size and hugged Y/n's side.

Tanjiro: I think that means she's not afraid to cut off her head for you, too. Despite what you think of yourself or what you want others to think about you, we'll always think kindly of you.

Tanjiro hugged Y/n, making him hug the two back.

Y/n: Thank you both.

Nezuko fell asleep while still clinging onto Y/n.

Y/n: Can't say I'm surprised.

Tanjiro: Even though I'm in a lot of pain right now, I have to keep pushing forward. That's because I'll be a grown man one day. And then, I'll become old and pass on. After that, if Nezuko is still a demon, she'll be lonely.

They got off the bed as Y/n laid Nezuko comfortably on a pillow and covered her up.

Tanjiro: Y/n, your immortal like Nezuko too, right,

Y/n: I am.

Tanjiro: Well then, I want to ask you something. If I die before we find the cure for Nezuko and you, I want you to take good care of Nezuko.

Y/n: I will. On that, you have my wo- Wait, for Nezuko and me?

Tanjiro: Yeah. After we cure Nezuko, I'm hoping that we'll have enough to turn you back, too.

Y/n: Tanjiro, thank you. You go on to your room, I'll catch up.

Tanjiro: Okay.

Tanjiro left Y/n who looked at the sleeping Nezuko.

Y/n: I will cure you and make sure you can life a normal life as a human. Even if I have to die in the process.

Y/n gave her a quick peck on the cheek.

Y/n: (blushing) Why did I do that?

Y/n walked out of the room and saw Tanjiro  struggling to walk.

Y/n: Sorry, Tanjiro. I forgot it would be difficult for you.

Y/n helped Tanjiro walk.

Inside the room.

Nezuko had her eyes opened wide as her entire face was red.

Nezuko: (Thinking: Ah! If you wanted a kiss you could've just asked!)

Later at night.

Tanjiro was asleep while Y/n watched him.

Y/n: You wait here patiently, while I go receive some ire.

At the Mansion.

The Hashiras were sitting with the Master.

Uzui: Where is that kid?

Shinazugawa: Honestly, if he's gone rogue again I'll hunt him down myself and gut him like a catfish.

They felt a slight breeze outside, turned and saw Y/n leaning against the wall.

Y/n: My, that doesn't sound too nice at all.

Shinazugawa: Y/n, you bastard!

Ubuyashiki: Sanemi, please be calm.

Shinazugawa: As you wish.

Y/n: Now, for my report.

Uzui: At least we'll get something.

Y/n: Master is the only to hear my report.

Iguro: ...Care to run that by me again, brat?

Ubuyashiki: Everyone except Y/n is excused for now.

Iguro: What? But, Master...

Gyomei: The Master has spoken... Let us go.

All the Hashira left, but some gave Y/n the stink eye before they left.

Y/n: I am sorry to make them leave, but I feel this information would be better given in privacy.

Ubuyashiki: I understand.

Y/n: Now, my info on Kibutsuji is limited, but here's what I do know. He looks like a man in his early twenties, his irises were blood red, he looked to be the same height and weight as Shinazugawa. And if I were to be so bold to say this, he had a similar facial structure as you, Master.

Ubuyashiki: I receive no offense. Thank you very much, Y/n. I will call you again when you are needed. Until then, you are dismissed.

Y/n nodded and left the room.

Ubuyashiki: Muzan Kibutsuji, I swear that I shall defeat you. We will bring you down without fail.

Outside.

Y/n was walking and passed by the Hashira.

Y/n: I can tell that some of you are not happy with me.

Shinazugawa: That's a big understatement.

Y/n: Come now, what could I have possibly done that would have earned me this ire. And I mean besides stabbing you and being half demon.

Uzui: Gee, let's see. You broke the rips and arms of two policeman in Akusa.

Y/n: I'll admit to that, but tell me, did you honestly care.

There was a moment of silence.

Uzui: No. But it wasn't as dramatic as the next thing you did.

Y/n: Which is...

Shinazugawa: You sat a Mansion on fire!

Y/n: I did? Ha, I'm hilarious.

Tokito: It took us 3, um...

Gyomei: Hours.

Tokito: Hours to contain that fire.

Y/n: Do you honestly care?

Tokito: No. I'm sure the birds, rabbits and snakes that got caught up in it did.

Y/n: Well good. I hate snakes.

Iguro's snake hissed at him.

Shinobu: Moving on. You also kicked me.

Iguro: And last, but certainly not least, you broke my jaw.

Y/n: You have bandages. Also, Tanjiro's jaw broken, but you don't see him complaining. Now, I'd love to stay here and fight with you some more, but I've got friends to get back to.

Y/n walked off.

Rengoku: If he was turn into a half demon against his will, I would understand it! But I do not understand why Y/n is defending this demon girl!

Uzui: It just doesn't make sense. Like Shinazugawa, Y/n had an intense hatred for demons until it came to...

Uzui's eyes widened.

Uzui: The girl.

Shinazugawa: What? No, no, no, no! He is not putting us at risk for demonic sex!

Tomioka: What?

Shinazugawa: Listen, I did not spend 2 years of my life teaching that little shit so he could get laid.

Rengoku: Shinazugawa, we cannot have such thoughts.

Tomioka: Regardless of his intentions, we'll have to wait and see what happens next.

Preview.

Uzui: I still can't believe that some demons don't attack humans and that you're half of one, Y/n.

Y/n: What are you, related to Iguro now?

Uzui: Your sarcasm is as amusing as ever.

Rengoku: Do you by chance have a clue to point us to Kibutsuji's where abouts?

Y/n: Well here's something that proves he's the ass we all make him out to be. He turned a guy into a demon and while me and Tanjiro were trying to control the situation, he got away.

Rengoku: I see. Now, it is time for a Taisho-era! I hear that the Master is the 97th leader of the Corps! We Hashira must do our part and be the fabric that holds the Demon Slayer Corps together! Are you prepared for that, Sound Hashira?

Uzui: Of course, Flame Hashira! Hope you're ready for it, Y/n!

Y/n: I will be. Me and Tanjiro shall slay the Kizuki and Kibutsuji.

Uzui: Next, Chapter 24, "Reh-

Y/n: Wait, there's gonna be a Light Novel first!

Uzui: A Light Novel?! How come I was not informed of this?!

Y/n: It'll fully explain why I am where I am now.

Rengoku: A great purpose!

Uzui: I like it. It better have a flashy name.

Y/n: Next, "Y/n Gaiden: Book of Morning Dove."

Uzui: Not a bad name I guess, could be more flashy, though.

To Be Continued.
