You managed to land on a platform as you saw Tanjiro falling!

(Y/N): BLACKWHIP!

With one catch, you threw Tanjiro to your position.

Giyu was also nearby, coincidentally!

(Y/N): Giyu!

Giyu: Are you both okay?

(Y/N): Yeah, for the most p- LOOK OUT!

You knocked him out of the way, and-

(Y/N): HINOKAMI KAGURA: SUN HALO DRAGON DANCE!!

You took out a swarm of demons in the way!

And then more came out!

(Y/N): HINOKAMI KAGURA: FIRE DANCE!

Tanjiro: WATER BREATHING: SIXTH FORM-

Giyu: WATER BREATHING: THIRD FORM-

Tanjiro and Giyu: TWISTING WHIRLPOOL!/DANCE OF THE FAST-MOVING CURRENT!

All the demons were torn apart.

(Y/N): How amazing. Yet again, I have Tanjiro and one of the Hashira here with me.

Giyu: We need to go.

(Y/N): Yeah, I know, Captain Obvious.

You fixed your haori.

(Y/N): Kyojuro, we're going to end this.

Mitsuri and Obanai were stuck together...

Mitsuri: I hope (Y/N) is alright. And the others ... I hope they didn't-

Obanai: Kanroji!

Obanai charged at a swarm of demons!

Obanai: SNAKE BREATHING: FIFTH FORM: SERPENTINE COIL!

He went into a serpent motion and cut off a bunch of their heads!

Obanai: Shitheads! I won't let you hurt Kanroji. She's going to be married!

Mitsuri: Well done there Mr. Iguro!

Obanai: Are you alright?

Mitsuri: I'm great! Say, I wonder, do you think (Y/N) would be good at your technique?

Obanai: ... I don't know how to even answer that. But I guess so.

Mitsuri then pictured you doing that.

Mitsuri: EEEEEEEEEE! THAT WOULD BE SO COOL!

Blake and Yang ended up with-

Muichiro: Are you two alright?

Yang: Yeah, just peachy. Except my butt hurts from that fall.

Blake: It's not damaged?

Yang: Heh, it's purrfectly fine for you Kitty.

Blake: (blushing) Heh. Okay, I'll give you that one.

Gyomei: We must focus. Let us not let Master's death go to waste.

Blake: Poor Kagaya. He didn't ... deserve a death like that.

Muichiro: Why? Why did he have to-

Yang: The guy was a walking corpse at this point. But, he remembered all of us. He kept on making us go on like- That fucking asshole!

Muichiro: (with tears) Muzan ... he took my brother from me, and our second father! I swear, he's dead!

Gyomei: I feel ... the same.

With Sanemi...

Sanemi was in a state of trauma.

Sanemi: Master. I'm sorry. I failed you. I-

A demon lunged for him, and-

Sanemi: YOU FUCKING DEMONIC PIECES OF SHIT!

He hacked one into pieces!

Then more started to come in.

Sanemi: BRING IT ON YOU FUCKING ASSWIPES!

With Weiss...

Weiss: (Y/N)?! RUBY?! BLAKE?! YANG?! TANJIRO?! I'll even settle for Zenitsu or Ino-

???: AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAARGH!

Inosuke appeared killing a bunch of demons.

Weiss: Oh what do you know, he showed up.

Inosuke: HAHAHAHAHAHAHAHAHAHAHAHA! LICE! PERFECT TIMING! I don't know how you got in here, but this is the perfect chance to test out the results of our training! Let's go! Lord Inosuke commands it!

Weiss: I'M NOT YOUR SUBORDINATE!

Weiss followed after Inosuke.

Genya was also in here...

Genya: Is this place where the Demons made their spot? Bro, (Y/N), Tanjiro, please be safe.

And Ruby...

Ruby fell right onto-

???: AGH!

Ruby: AGH! ZENITSU!

Zenitsu: Why me?

Ruby: I'm sorry!

She got him up.

Zenitsu: Do you hear that?

Ruby: What?

Zenitsu: (angered) He's here. THAT FUCKER!

Ruby: Who?

Zenitsu: Kaigaku.

Ruby: WHO?!

As for Shinou...

Shinobu wandered into a place where she saw naked women all bloodied and with severe wounds.

Shinobu: What is ... this place?

She felt uneasiness as she continued forward.

???: Oh, someone's here?

Doma appeared, dropping a girl he just had his way with.

Doma: My goodness, you look so beautiful, and delicious too. Nakime really knows how to pick them.

As Shinobu saw him-

Shinobu: Y-YOU!

Flashback...

Kanae: Shinobu, please leave the Demon Slayers. I know you work really hard. But you're better off ... I just want you to find happiness like any normal girl. And live until you're old. That's enough for me.

Shinobu: (crying) NO! SISTER! I WON'T QUI! I WIL AVENGE YOU! TELL ME! WHO WAS THAT DEMON?! THE ONE WHO DID THAT TO YOU! I CAN'T LIVE A NORMAL LIFE AFER SOMEONE DID THIS! PLEASE!

Kanae: It ... was a demon ... who had blood stains on top of his head. He spoke in a clam, gentle manner. And he had a carefree smile.

Present...

Doma: I am Doma, Upper Moon 2, it's a very nice night out tonight, isn't it?

One of the girls was still alive.

Girl: (traumatized) Help me! HELP M-

Doma: Now that's rude. There is no talking to be-

Shinobu grabbed her out of the way.

Shinobu: Are you alright?

Doma: My, what speed! Are you a Hashira?

The girl tried to speak, but she coughed up lots of blood.

Doma: Well, I say you should just leave her. I'll make sure to devour her. She wasn't that much fun to play with anyway.

He then brought out two golden fans.

Doma: You see, I'm the founder of the Eternal Paradise Cult. My duty is to make all f my worshippers happy. So I'll eat her up without leaving a single speck.

Shinobu: Did you say make everyone happy? You're insane! She was screaming for help!

Doma: Yes, and I saved her. She doesn't feel anymore pain or suffering. Everyone is afraid of dying. And so, I give them some pleasure, and then kill and eat them. Now they get to live inside of me forever. Blood, flesh, all of it. I made sure to accept, rescue, and guide them to enlightenment.

Shinobu: You make me absolutely sick you monster!

Doma: Huh? How come you're being this harsh even though we just met? h wait, I see. If there's something bothering you, you could tell m-

Shinobu: OH YOU DON'T KNOW WHAT'S BOTHERING ME?!

Her demeanor changed.k

Shinobu: LOOK AT MY HAORI! THIS IS THE HAORI OF MY SISTER, WHO YOU RAPED AND MURDERED!

Doma: Oh, you mean Kanae, the Flower Hashira from before? Oh my. Yes. She was such a beautiful and cute girl. It's a shame I couldn't eat her. After I had my way with her, the sun was coming up. Pity, she would have tasted wonderful. I-

Shinobu: INSECT BREATHING: DANCE OF THE BEE STING!!!

Shinobu stabbed Doma in the left eye!

Doma: Oh, nice stab there. I couldn't stop it. BLOOD DEMON ART: LOTUS ICE!

His swiped his fangs creating ice flowers!

Shinobu got back, but they were spreading to her!

Shinobu: AGH! These are so cold. It could shred someone's lungs apart!

Doma: Fast one aren't you? But it's a shame. You can't kill demons ith stabbing. It's the neck you need to go for.

Doma licked the blood from his eye.

Shinobu: But then how about poison?

Doma: What?

He felt weaker as poison spread through his body!

Shinobu: I hope this works on an Upper Moon.

Doma: AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAGH!

Doma coughed up fountains of blood!

Doma: Okay, I'll give you this. That actually is good. BLEGH!

Shinobu: It can adapt to any demon.

Doma then got up.

Doma: Your blood, it makes a very unique sound when you put it in your sheath. Is that where your poison mix is? Well, this is going to be fun! Getting attacked with poison is interesting! What else do you have?

Shinobu: I'll show you what I got!

Doma began to remember his past.

Before he became a demon, his parents made him the leader of their cult. He was worshiped and adored as God.

Though it began to bore him.

To Doma, gods don't exist, and neither does the Buddha. He lived for decades without realizing it.

Whenever someone died, he kept their skulls to himself.

After a while...

Doma: That's the fifth one. Do you have anything else? This isn't working. And it's getting less and less effective.

Shinobu: So this is the strength of an Upper Moon. Poison isn't working! And he's getting resistant!

Doma: Your lungs are undergoing necrosis now, huh? After all, you took a blow from my Blood Demon Art.

Shinobu: I'll just have to keep hitting him over and over. INSECT BREATHING: DANCE OF THE DRAGONFLY: COMPOUND EYES: HEXAGON!

Shinobu struck him over and over again with several blows!

Doma was bleeding and impressed.

Doma: You are really fast. Probably the fastest Hashira I've ever met.

She was hit too though!

Shinobu: AAAAAAAAAGH!

She fell down and got up on one knee.

Doma: You could have just cut my head off. But I guess it couldn't work. You're jut a cute little girl after all. Not much upper body strength is there?

Shinobu looked down as the blood dripped on her hands.

Shinobu: Why do I have to have small hands? Why am I so short? If I was a bit bigger and strong, would I have been able to cut off his head? Hands ... legs ... the bigger they are, the more muscle mass they have. But Sis was so dainty and thin despite being taller than me. Mr. Himejima has it nice. Everyone is reassured when he goes to save people. And I know what she was trying to tell me. That I would lose.

But then she saw her sister.

Kanae: Shinobu, get it together.

Shinobu: S-Sis.

Kanae: Stnad up.

Shinobu: I can't. I can't go on anymore. I feel like my lungs are-

Kanae: Stand up, Insect Hashira, Shinobu Kocho. If you resolved to beat him. If you resolved to win, then win. Win no matter what. You promised me and Kanao.

Doma: Oh sorry about that. I guess I gave you a half-hearted slash there.

Kanae: I believe in you, Little Sister.

Shinobu then turned to him.

Doma: Oh, you're still standing? Are you even human? Your lungs and ribs should be smashed at this point. And the blood's going into your lungs, making grumbling sound. You must be in a lot of pain. You're dead. You might as well-

Shinobu: INSECT BREATHING: DANCE OF THE CENTIPEDE: HUNDRED LEG BELLOWS!!

She charged at Doma, as he tried to swing his fans, only for her to stab him in the chest!

Shinobu: AS LONG AS I CAN KILL YOU, HUNDREDS OF PEOPLE WILL BE SAVED! I LOST MY PARENTS! MY SISTER! MY SUCCESSORS! EXCEPT FOR KANAO! AND THE SAME IS FOR MY GIRLS! IF ALL OF THEIR RELATIVES HAVEN'T BEEN KILLED BY DEMONS, THEY WOULD HAVE MUCH BETTER LIVES! PEOPLE LIKE YOU PISS ME OFF!

But then-

Doma: OH MY!

He grabbed her!

Shinobu: AGH!

Doma: OH THAT WAS AMAZING! I'M SO MOVED! I NEVER EXPECTED A WEAKLING LIKE YOU TO GO THIS FAR!

Shinobu: Go to hell!

Doma: Oh, but first-

He began to forcibly strip her.

And then-

Kanao: MASTER!

Shinobu: K-KANAO!

Kanao: AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAARGH!

She screamed in rage as she charged for Doma!

Meanwhile...

Ruby and Zenitsu found a room.

Zenitsu: I know you're here. Come out.

???: Hey, come on Zenitsu, that's no way to treat your elder disciple.

Kaigaku (Former Disciple of Jigoro the Thunder Hashira! Elder student to Zenitsu! He's the bastard who is responsible for Gyomei being arrested and joined up with Muzan in order to get stronger! Master of Thunder Breathing!)

Kaigaku: Long time no see.

Zenitsu: Kaigaku. You are no longer my senior.

Ruby: WAIT, WHAT?!
