Recap.

When Tanjiro and Y/n with the two kids walked outside of the mansion they saw Zenitsu closely holding Nezuko's box while being beaten by the boar guy.

Boar guy: Take this! Come on! Move it! Now, you spineless coward! Draw your sword and face me!

Boar guy: You leave no choice but to take you out along with that box!

The boar guy was about to bring one of his swords down, but Y/n blocked the strike.

Y/n: Listen, this guy behind me might be a coward, but he doesn't deserve this. And if you don't stop, I'm gonna have to make you.

While Y/n was holding one of the boar guy's swords, Tanjiro came from the side.

Tanjiro: Get away!

He punched the boar guy in the center of his chest, cracking a few of his ribs.

Zenitsu: I heard him! He broke his ribs!

Tanjiro: Aren't you part of the Demon Slayer Corps? You must understand why Zenitsu refuses to draw his sword. Because it's taboo for us to fight each other without provocation! But here you are giving him a complete one-sided beating. Is that fun for you? You are the lowest of the low.

Y/n: Says you.

Tanjiro: Huh?

Y/n hit Tanjiro in the head.

Tanjiro: Ow, what was that for?!

Y/n: I have no objections to you invoking the rules of the Corps, but you stepped in when he was distracted with me. That's dishonor, something I will not tolerate.

Tanjiro: (sigh) I know.

As the boar guy laid on the ground, he started cackling.

Boar guy: So that's how you feel? I didn't realize. In that case, let's fight barehanded.

Tanjiro: No! Did you even hear a word I just said? Listen...

The boar guy got up and ran at Tanjiro.

Tanjiro: We're not supposed to fight each other in anyway!

The boar guy threw kicks and punches at Tanjiro who was able to avoid them.

Tanjiro: Using your hands doesn't change things! Are you listening to me?

The boar guy got on Tanjiro's neck and spun around, threw Tanjiro and a kick at him, cutting some of his hair as everyone else watched.

Y/n: Listen, Zenitsu. I'm going to treat that noise bleed and black eye, but only because you protected the box and so I won't owe you any favors later.

Zenitsu: I'll take it.

Y/n took out some cloth and put pressure on Zenitsu's noise.

Y/n: Keep pressure on your noise until the bleeding stops.

Zenitsu did what he was told.

Y/n: I don't have anything for your eye though.

Zenitsu: Forget that. How is that boar guy able to move like that? And with some broken ribs no less.

Y/n: Those are some flexible joints he has. He might even be more flexible than one of my former ladies.

They continued to watch the fight.

Zenitsu: If we're being fair here, Tanjiro's guilty of going against the rules as well. He broke his bones.

Y/n: To be fair, I would have just knocked this guy out and it would've saved us this shit.

They continued to spectate.

Y/n: Woah. He nearly got Tanjiro's nuts. With as low as his attacks are, it's as if Tanjiro was fighting a real boar.

Tanjiro tried to sweep kick the boar guy, but he ducked and struck Tanjiro's head with a kick in a wheel position.

Boar guy: What did you think of that move? Pretty damn amazing, don't you think?!

Zenitsu: He's singing his own praise. Give me a break.

Y/n: I've seen better!

The boar guy looked at Y/n.

Boar guy: What did you say?!

Y/n: I think I said, "I've seen better."

Boar guy: Why you-

Y/n: Take that how you will, but if you choose to engage in combat than for the sake of defending myself, I will have no choice but to fight back.

Boar guy: (cackle) Challenge accepted! But first, let me demonstrate what else I'm capable of.

Y/n: Now that's definitely not something you see everyday.

Tanjiro: Stop it! What are you doing? Performing a stunt like that in your condition won't be good for you!

Boar guy: Who cares?!

He threw a punch at Y/n who ducked and tried to kick the boar guy, seemingly missing, but the boar guy got a small cut on his chest, shocking Tanjiro and Zenitsu.

Zenitsu: How'd did you do that?!

Tanjiro: I thought your sword only did that!

Y/n: That was a little trick I learned from my master.

Boar guy: Not bad, but try to dodge these!

The boar guy threw multiple punches which Y/n swiftly dodged them, then kicked the boar guy in the chin.

Zenitsu: Ahhh! Did his lower jaw just get fractured?

The boar guy tumbled back and his mask fell off, revealing his face.

Zenitsu: Huh?! Are you kidding me?! That's what you look like?!

Boar guy: What the hell are you saying?

He had a girly like facial structure, short hair with blue tips and big green eyes.

Boar guy: You gotta problem with my face or something?

Zenitsu: I don't know what to make of you right now. You've got this ripped body, but such a delicate base to go with it.

Boar guy: What? Why are you so obsessed with my face all of a sudden?

Zenitsu: I'm not! It was just an observation!

Y/n: It's just it wasn't the face we were expecting.

Tanjiro: Yeah, there's nothing wrong with your face. In fact, the girlish shape, size, and complexure are quite attractive!

Y/n: You didn't need to say that, Tanjiro.

Boar guy: You're a dead man! You wanna go!?

Tanjiro: I don't! I don't want to fight you anymore!

Y/n: Why don't you sit down, breathe, and relax.

Inosuke: I've got a better idea. How about I tell you my name? It's Inosuke Hashibira! Don't you forget it!

Tanjiro: How is that spelled exactly?

Inosuke: I don't know how to read or write, okay? All I know, is that name was written on my-

Y/n swiftly appeared behind him and knocked Inosuke with a swift chop the neck.

Tanjiro: Y/n!

Y/n: I'm sorry, it's just that he would have kept going on. It's actually pretty amazing that he was able to stand with broken ribs and still talked with his lower jaw being fractured.

Zenitsu: What's more amazing is how there's not a scratch on you. I thought Tanjiro said you used all your power in your last mission.

Y/n: I did, but I recovered.

Zenitsu: That fast!

Y/n: Okay, kids, you run along now. But first, Hatake!

Hatake flew down gave Y/n a small light purple pouch.

Y/n: Here.

Y/n gave the pouch to Kiyoshi.

Y/n: This is a Wisteria scent bag. If you hold on to it, demons will stay away from you.

Kiyoshi: Thank you. But don't you need help burying all those bodies?

Y/n: We won't need to worry about those.

Tanjiro: Y/n, even if you don't want to do it those people need a proper burial.

Y/n: No, Tanjiro. You misunderstood me. What I meant was, we won't have to worry about the bodies because once I'm done, there won't be any bodies to bury it all.

Later.

It was dusk and the three along with Inosuke with his boar mask back on were walking down the mountain.

Y/n: So much time went by?

Zenitsu: How did that even happen?

Y/n: What, you don't remember us burying the bodies near the mansion and Inosuke here waking up for a challenge which he took of burying the bodies, then when we tried to leave you begged that Shoichi kid to go with us and when we pulled you away from him Tanjiro's Crow came to us and told all of us to rest at the Wisteria Family house?

Zenitsu: No! I don't remember any of that! Because none of that happened!

Y/n: Really? None of it?

Tanjiro: What did happen then?

Zenitsu: Those kids called Y/n's bluff and in response he custered out and burned the mansion down!

Y/n: No I didn't, you fucking nut job. I didn't burn it down because it's still on fire.

The mansion was showen and it was on fire.

Inosuke: Damn, W/n, you're one crazy son of a bitch!

(A/n: W/n stands for wrong name.)

Y/n: It's Y/n, and I get that a lot. Now, we really are going somewhere we can rest up.

Tanjiro: And you called it, "The Wisteria Family House"?

Y/n: Correct. Now, let's get a move on.

After they continued walking, it was night and they stopped in front of a house with the kanji of "Wisteria" on the front gate.

Y/n: This is it. Any of you ever heard of this place?

Inosuke: Never, all I've done was kill demons.

Y/n: Understandable. Just let me do the talking.

Y/n knocked on the door and when it opened they were greeted by a short old lady with a red kimono and a blue obi belt.

Old lady: Yes?

Y/n: Hello, miss. I was wondering if me and my friends here could possibly stay the night. If that's okay.

Old lady: I'm assuming you're Demon Slayers.

Y/n: You would be correct. Here.

He showed here the back of his right hand and the kanji for Mizunoe appeared on his hand.

Old lady: Please come in.

Y/n: Thank you, ma'am. Come on, guys.

They followed the old lady inside.

Zenitsu: That little old lady sure is fast!

Old lady: This is where you'll be staying.

They walked in and the old lady presented them with four white kimonos with black Obi belts.

Old lady: A change of clothes to cleanse your body.

They changed and saw the old lady also prepared four plants of food.

Old lady: And a warm meal to cleanse your soul.

Zenitsu: She has to be a monster! Preparing all of this so quickly, there's no way she's human! She can't be-

Y/n covered his mouth.

Y/n: I'm sorry, ma'am, he doesn't have an off switch.

They sat down and Inosuke was going at the tempura eating with his bare hands.

Zenitsu: Use your chopsticks.

He eat some of Tanjiro's tempura and gave him a cheekey grin but Tanjiro just offered the rest to him.

Tanjiro: If you're really that hungry Inosuke, you can have this bowl, too.

Y/n: Look, you seem to like tempura, so you can just have mine. I never really liked tempura that much anyway.

Inosuke: I refuse!

Y/n: Well, if I were to offer some advice, don't eat so fast with your jaw being fractured.

After they got done eating, the old lady prepared four futons for them.

Old lady: You're bedding is ready, gentlemen.

Y/n: Thank you for everything.

Old lady: I require no thanks, Master Y/n.

Inosuke took the one on the far left.

Inosuke: I'll take this one! First come, first serve!

Y/n: Whatever. I guess I'll take a middle one.

He laid down, Tanjiro got the one right next to Y/n and Zenitsu took the last one. The old lady came to them with a doctor who checked on them. Zenitsu, Tanjiro, and Inosuke all had broken ribs, but couldn't find anything wrong with Y/n.

Zenitsu: Who would've guessed we all have broken ribs.

Inosuke: The bottom of my mouth hurts a lot more.

Y/n: I told you not to eat so fast.

Zenitsu: Y/n, how come you're not hurt at all?

Y/n: I have my ways. My turn to ask. What Breathing style do you both utilize?

Inosuke: Utilize?

Zenitsu: He means what Breathing styles we use.

Y/n: Yeah, Tanjiro uses Water Breathing while I use Wind Breathing.

Zenitsu: Well, I use Thunder Breathing.

Inosuke: You saw my Beast Breathing.

Tanjiro: You never told me anything about Beast Breathing before, Y/n. And what about that thing you used inside the mansion? I think you called it, "Bird Breathing."

Y/n: Yes, well, that's because they didn't exist back then. Allow me to explain.

Y/n took a piece of paper and wrote some sort of chart on it.

Y/n: The five in the middle are the fundamentals of Breathing styles. Flame, Water, Wind, Stone, and Thunder. Anything that aren't those five are branches off of them. For example, Flower Breathing and Serpent Breathing are branches off of Water Breathing. Sound Breathing is branched off of Thunder Breathing. And Mist Breathing is branched off of Wind Breathing.

Tanjiro: What about your Bird Breathing and Inosuke's Beast Breathing?

Y/n: I took advantage of my strong leg muscles and what I've learned under my under the Wind Hashira and made my own style. So, Bird Breathing is branched off of Wind Breathing, too. Beast Breathing even though I've only seen it once, I can tell that it's distantly branched off of Wind Breathing.

Zenitsu: Wait, did you say Wind Hashira?!

Tanjiro: What's a Hashira?

Y/n: They're the strongest swordsmen in the Demon Slayer Corps ranks. There's one for each Breathing Style. Giyu Tomioka held the Water Hashira title.

Zenitsu: And my teacher was the former Thunder Hashira.

Inosuke: So I'll be considered one of the strongest Demon Slayers if I become one of these Hashira?

Y/n: You definitely will, but you need to meet the right conditions, but that's another story for another time.

Zenitsu: Well, that Wind Hashira must be proud to know you're a strong Demon Slayer.

Y/n: Oh no. See, these days that man and I don't exactly see eye to eye. I burned all the bridges I had with him and the rest of the Hashira.

Zenitsu: Why?

Y/n: Because I became a half demon.

Inosuke: What?!

Zenitsu: That explains that weird sound you give off.

Tanjiro: Y/n, the question I'm about to ask you is something that's been bothering me for awhile.

Y/n: What is it, Tanjiro?

Tanjiro: This Demon you wanna kill, do you know what its name is?

Y/n: I do. And the shameful truth is it was my own blood. My elder brother, B/n L/n.

Tanjiro: What?! Your brother did this to you.

Y/n: Not all brothers can be a shining hero you are, Tanjiro. Mine is a total dip shit who I devoted my life to killing.

Tanjiro: Then what will you do after?

Y/n: Once I kill my brother, I'll re-pledge my loyalty to the Demon Slayer Corps and beg for everyone's forgiveness.

Tanjiro: So, you did regret stabbing them.

Y/n: I did.

Zenitsu: Well, completely unrelated subject. What's the deal with this place?

Y/n: This house belongs to a family who was rescued by Demon Slayers, so now they let us Demon Slayers rest here free of charge. They're especially caring towards me because my family played a big part in that rescue.

Tanjiro: Now that I think about it, what made you want to join the Corps, Inosuke?

Inosuke: A member of the Demon Slayer Corps barged in on me on my mountain, so we competed to see who was stronger, I took his blade as a reward. Then, I heard in this thing called "Final Selection," and the fact that demons really do exist.

Tanjiro: So, that's what drew you to the Demon Slayer Corps? And hey, you grew up in the mountains, same goes for me.

Inosuke: Don't lump me in with you! I don't have anyone I can call family! Only one thing gives me comfort in this world (puts mask on) and that's testing my strength against others!

Tanjiro: Is that so? How sad.

Y/n: One of my former masters would encourage you to get stronger while the other would cry for you.

Zenitsu: Tanjiro, there's something I've been meaning to ask you. You're traveling with Y/n who is a half demon and a normal demon, what's that about?

Tanjiro: Zenitsu. You knew, and you still protected the box. You really are a good person, you know that? Thank you.

Y/n: He might be a good person, but a weak one.

Zenitsu: You're both right about that.

Nezuko's box started shaking.

Zenitsu: Ah! Is it coming after us?!

Y/n: Relax. Nezuko, you can come out.

Zenitsu: Nezuko? Isn't that a-

Nezuko got out of the box with her muzzle back on and grew to her high.

Tanjiro: Hey, Nezuko! I'll introduce you. Nezuko is my-

Zenitsu: Tanjiro... Y/n...

He turned to Zenitsu who was looking down.

Zenitsu: You didn't... tell me you didn't.

Zenitsu raised his head with his eyes wide.

Zenitsu: Just who do you two think you are?! You've been traveling with a girl this adorable?! Hanging out with someone this cute day in and day out, and been having a great time in the process, haven't you?

Y/n: Well, he's not wrong about some of that.

Zenitsu: Well then why did I bare all that pain and suffering!? Tanjiro, Y/n you jerks. You both going all ohh and wee with a cutie is not what I was totaling away for! I did not put myself in harms way to be pummeled and kicked by a crazy boar guy!

Tanjiro: Zenitsu, calm down. What's gotten into you?

Zenitsu: Did you think I joined the Demon Slayer Corps because I thought it was gonna be all sunshine and rainbows!? Guys like you should be erase from this world! Immediately! I will see to it you both pay.

He drew his sword.

Zenitsu: You two shall face justice! Don't ever disrespect the Corps!

Y/n blocked Zenitsu's strike.

Y/n: You're gonna have to get through me if you want Tanjiro.

Zenitsu: Challenge accepted ,you psycho!

Chaos went on for the full night.

Meanwhile.

At the burning mansion.

Sanemi was there with a gaint blind guy with short black hair, a scar across his forehead, red beads, and a green haori over his Demon Slayer Corps uniform, but it looked really small.

Sanemi: Yeah, he was definitely here. He's the only son of a bitch I know that's crazy enough to pull a stunt like this.

Gaint: (crying and praying) It truly is sad. I pray we find him soon.

???: What did this guy even do that made us go after him again?

They turned and say a boy with long black hair that reached to the end of his back, teal tips and eyes, that his Demon Slayer uniform looks like it's three times bigger than him.

Sanemi: Right, you're new to our ranks, Tokito. Just remember that as soon as we find that ungrateful bastard, I'll cut his belly and cut him to pieces.

Gaint: (crying) Shinazugawa, I'm hurt by Y/n as well, but please remember Master wants him back alive.

Tokito: Whatever. I don't even know this guy, so it doesn't really matter to me.

Zenitsu: But this is my natural color.

Tomioka punched him in the face.

Tomioka: No talking back!

Zenitsu: Come on!

Tomioka: No holding bread in your mouth!

Y/n: With all do respect, Mr. Tomioka, she has a condition so she needs that bread.

Tomioka: Good way of talking. What's your name?

Y/n was wearing an all black male school uniform with long sleeves.

Y/n: Y/n L/n. Aiming to be the next student body president.

Tomioka: No eye contacts.
