Nezuko had kicked Daki destroying some of her head as she was beyond furious.

Ruby: Nezuko, you can't fight this one!! Just leave her to me!!

She didn't listen and rushed forward to Daki. The Upper Moon used her sash to cut off Nezuko's leg.

Daki: You lowly Demon!!

She cut off her arm and separated her torso sending her flying to another building.

Ruby: 'Nezuko has never eaten a human before. There's no way she can keep up with Daki. Especially since she's powered up!'

Ruby quickly got up feeling the strain leaving her body. She looked and saw Nezuko was getting up with everything but her arm healed.

Ruby: Wait, that's weird. Nezuko was definitely cut up before, but now seems almost fully healed.

Right then before their eyes her arm had regenerated at frightening speeds. Nezuko opened her mouth as the bamboo fell from it revealing her razor sharp fangs. Markings appeared over her body as she grew with a horn appearing on her head.

Ruby: What could it mean?

Nezuko tried kicking Daki again but her leg was cut off. Though somehow she was still hit by the kick as she crashed into the ground.

Ruby: HUH?!!

Ruby was unsure what to think as she contemplated what she saw.

Ruby: Th-That wasn't just pure regeneration.

The moment played back in Ruby's mind as Nezuko's leg still hit Daki.

Ruby: 'Nezuko's blood held her leg together!'

Daki cut Nezuko up but saw for herself that Nezuko's blood had solidified and caused her to stop her sashes. The next second Daki was lit on fire by Nezuko's blood making her scream in agony. Nezuko reattached herself and kicked Daki's head in with a sadistic grin before kicking her through multiple walls.

Ruby: I might wanna stop this now.

Ruby had flashed down onto the ground and saw Nezuko looking at people who were terrified smelling their blood.

Tanjiro: NEZUKO!!!

Before anything else could happen both Tanjiro and Ruby held her back.

Ruby: COME ON CHILL OUT!! IF YOU HURT THEM WE'LL HAVE TO EXECUTE YOU AND YOUR BROTHER!!

Nezuko growled viciously as Daki shook the flames off angrily coming back to attack.

Tanjiro: I'M SORRY!!! I'M SORRY FOR MAKING YOU FIGHT!!!

Daki: YOU'RE ALL MINE!!!

They saw Daki coming to attack as she was fully healed and free from the flames.

Ruby: 'AH CRAP!!'

They waited for unimaginable pain but even after 10 seconds of closing their eyes it never came.

???: Man, looks like there's been a real hot mess while I was gone.

They all heard a familiar voice and opened their eyes seeing Ryu holding all of Daki's sashes with his bare hands.

Tengen: Nice!!! Quite a Flamboyant entrance Ryu!!

Daki looked at Ryu confused.

Daki: You're new.

Ryu: What? The hell are you talking about, didn't I... Oh right that was my girl form.

Daki looked into his eyes recognizing the glow.

Daki: YOU!!

Ryu: Me.

He swung Daki around by the sashes and slammed her on the ground multiple times.

Daki: HOW DARE YOU!!

Ryu: Waist of my fucking day. You've got the strength nearing an Upper Moon, but let the real one come on out to play. Maybe it can give me a better work out.

Daki: What are you-

Daki felt her head fall off her shoulders and into her hands.

Daki: Huh?

Ruby looked in shock and a bit of irritation.

Ruby: FOR ALL THE TROUBLE SHE GAVE!!

Ryu: If you were using that power the right way you could've done this Rubes. Hell you could've done it without it probably. As for you.

Ryu looked at Nezuko seeing she was growling viciously.

Tanjiro: DON'T HURT HER!! SHE HASN'T EATEN ANYONE YET!!

Ryu: Calm down Tanjiro, I'm not gonna hurt her.

Ryu took out a cloth and began to wipe Nezuko's face of confusing everyone including her.

Ryu: Come on, you should keep yourself clean Nezuko, you're a young lady.

Tengen: ... What?

Shojo: Just what do you think that's gonna do?

Ryu: Enough.

Ryu patted Nezuko on the head smiling.

Ryu: Take a rest alright?

Tears fell from her face as the image of a man replaced Ryu. She stopped struggling before reaching out to Ryu. She hugged him and cried before shrinking down to the size of a child.

Ryu: Well the last part I didn't expect.

Tengen Ruby and Tanjiro all grabbed his collar.

Tengen: THAT'S IT JACKASS!!!

Tanjiro: EXPLANATION!! I NEED AN EXPLANATION!!!

Ruby: HOW THE HELL DID YOU CALM HER DOWN BY CLEANING HER UP?!!!!

Ryu: O_O How the hell did you not try being gentle with her?

He picked her up cracking his neck.

Ryu: Anyway let's just leave.

Daki: HANG ON!!! WHERE ARE YOU GOING?!!!

They looked to see Daki was talking with her head severed.

Ryu: ... The hell?

Daki: How dare you cut my head off!! You'll pay for this!!!

Tengen: Ugh, do you ever shut up? Just die plainly.

Ryu: Preach brother.

Daki: STOP JOKING AROUND! I mean, you said I wasn't an Upper Moon to my face a minute ago!!

Ryu: Like I said, you definitely have the strength and the eyes, but you aren't one. Speaking of, where the fuck is it?

Daki: I AM UPPER MOON SIX!!

Ryu: I mean even if you are I killed Upper Moon 2 and 3 at the same time. To me it doesn't matter.

Daki: I STILL HAVEN'T LOST!! I'M AN UPPER MOON!!

Tanjiro: ... Ruby, what's going on?

Ruby: Why do you think I'd know?

Daki: I'M ACTUALLY STRONG!! And I'm just number 6 now, so I'll just get stronger from here and...

Tengen: You're not convincing anyone about that here.

Daki began to cry shocking everyone.

Daki: I'M REALLY UPPER MOON 6!! I'M SERIOUS!! I'VE EVEN GOT THE NUMBER TO PROVE IT!! I'M SUPER AWESOME!!!

Ryu: ...

Shojo: ...

Tengen: ...

Ruby: ...

Tanjiro: ...

Ryu: 'How long is she gonna say like that though? I already cut her head off.'

Daki: DIE! DIE!! YOU'RE ALL GONNA DIE!!!

She began to hit the ground crying louder.

Ryu: Ok can you stop? You're just making me feel like an absolute asshole.

Daki: MY HEAD GOT CUT OFF!! IT GOT CUT OOFFF!! BIG BROTHER!!!!

From Daki a man with black and green hair emerged shocking everyone. Tengen slashed at them both but they disappeared. That's when they all heard a raspy and ghoulish voice.

???: Crying's not gonna help. At least attach your own yourself. You really are lacking in the brain department huh?

Ruby: Oh you HAVE to be kidding.

???: Man, your face got burnt? Take care of that thing.

Daki seemed to heal as the man wiped her tears.

???: You we're born with such a cute face after all.

Ryu had put down Nezuko and rushed two the Demons swinging his katana. The man turned looking at Ryu with the latter bringing his blade up with sparks flying and the man appearing behind him.

Ryu: Shit, that was close.

???: Heh, not bad. You completely blocked my attack there.

He held two sickles in his hands and looked as if he was starved as Ryu saw his Ribcage.

Ryu: Tanjiro, take Nezuko and get out of here.

Tanjiro: But-

Ryu: Go fast.

Tanjiro: ... Right!!

Tanjiro ran out of the room with Ryu ready for any attack.

???: And I struck with the intent to kill too. Nice man. NIIIICE.

Ryu stood in a higher stance calm and looking forward.

???: Niiice man. Niiice face. Niiice skin. No spots, no birthmarks, no wounds. Niiice flesh. A perfect amount of muscle even through your body. I can't get any fatter myself. And you're real tall. You're clearly over 6 feet there.

Ryu: 'What the hell is up with this dude?'

???: I'm sure you're really popular with the girls, man. The envy, OHHHH the envy. Could you just drop dead? And you'll get a really painful death now. I'll skin you alive and claw your innards out right after.

Ryu: That's if you can even touch me.

Daki: Big brother, he's not the only one!! Go kill the girl who burned me! Do it!!

She started crying again as Ryu simply was perplexed.

Ryu: 'So the casual being the bully but then the victim when the big bro's around huh? Thank God Amber was independent.'

Shojo: Some things are creepier than mindless fury.

Daki: I was working so hard! I was working super hard on my own...! And yet they all got in the way and bullied me!! They all kept bullying me!!

Ruby: -_- That's a bunch of lies and you fucking know it.

Ryu: 'And Ruby cursed. That's when you know it's bad.'

???: Yeaah, yeaah, unforgivable. My cute dumb sister was working hard. I'll kill anyone who tried to bully her.

Ryu: -_- You'll die trying.

???: Time to collect the debts. I'll collect one for every bruise they put on you.

Ryu: Pfft, damn. I put a lot so you'll be rich after.

???: I'll make you spin round and round when you die. BECAUSE MY NAME IS GYUTARO!!!

GYUTARO!!

He spun around with slashed going around as a small explosion occurred with Ryu easily dodging the sickles of the Demon that went out of the house before coming back to try and hit him. While that happened Tengen saved a man that was near him barely avoiding being hurt.

Ryu: Get out of here.

Gyutaro: The envy, MAAAAN, you really are a nice guy, huh? Protecting the humans, looking cool, niiice.

Tengen: Well, yeah. I'm a flamboyant, elegant ladies man, so of course. I even have three wives.

Ryu: Ok I'm done talking, just fight.

Ryu in a burst of speed kicked Gyutaro through the walls. He corrected himself mid air as he readied an attack.

Gyutaro: 'Blood Demon Art: Splatter Sickle!

Gyutaro sent blood slashes at Ryu who gripped his blade.

Ryu: Flame Breathing, 3rd Form Improved: Blazing Universe, Destructive!!

Ryu swung his massive sword down as a wave of flames shot towards Gyutaro. Although they overwhelmed the blood slices they couldn't reach them Demon as sashes whipped the flames away.

Gyutaro: You might be able to overwhelm me in power by myself, but don't forget.

Daki had appeared on Gyutaro's shoulders.

Gyutaro: My sister and I are one man.

Ryu: Great, Demons that are as big of a pain in the ass to kill as Akaza and Doma together. Hell now that you're out she's at least double charged.

Ruby: You'll need backup.

???: AND WE'RE HERE TO BRING IT!!

From the ceiling crashes Inosuke and Zenitsu, the latter of the two asleep. From the opening Tanjiro crashed in as well. Ryu grinned seeing this.

Ryu: Looks like a little more overkill's here.

Tengen: I think I found out how we're gonna do it.

Ryu: Same here. Cut off their heads at the same time. This won't even be a problem. You'll be dead-

Ryu held three fingers up.

Ryu: With 30 minutes.

Daki: That chance! The long night will always be the ally of the Demons!!

Daki appeared behind them as Ruby was the one to react blocking her sashes with her scythe.

Tengen: Kamado, Rose, help Ryu against the Upper Moon!! We'll handle the girl!!

They nodded as Ruby kicked Daki off of her. That's when they focused on Gyutaro as Ryu remembered something from his past.

Ryu: Guys, watch out for his blood slashes. If I'm right, they'll put poison right into your blood stream.

Both Tanjiro and Ruby looked at Ryu in disbelief.

Gyutaro: Niiice man, you somehow figured out my Blood Demon Art just by the look. Those eyes of yours are definitely special.

Ryu's eyes went slitted as Gyutaro said that.

Ryu: Get ready.

Gyutaro sped forward nearly impaling Tanjiro's jaw.

Tanjiro: 'NO!! MOVE, MOVE!!'

Before Tanjiro could realize it Gyutaro's arm was cut off. This was caused by Ryu as he grabbed his head throwing him back.

Ryu: Focus up Tanjiro.

Ryu disappeared as Gyutaro quickly regenerated clashing blades with Ryu.

Ryu: 'Magma Breathing, 3rd Form: Flowing Eruption!!'

Ryu increased his speed as he seemed to overwhelm Gyutaro cutting his limbs off causing him scorching pain.

Gyutaro: ARGH!!!

Ruby rushed forward breathing in.

Ruby: 'Inferno Breathing, 6th Form.'

Her Nichirin Scythe seemed to burn a hot red as she slashed him across the chest nearly cutting through him diagonally.

Ruby: Searing Flame Slash!!

He fell onto the ground before regenerating.

Ryu: Faster regeneration huh? Looks like my normal tricks won't cut it here.

He took a deep breath and gripped his sword even tighter.

Ryu: TANJIRO, RUBY, DUCK!!!

They both did as he said while he brought the massive blade behind him.

Ryu: 'Total Concentration: Magma Breathing, 8th Form!! Piercing Devastation!!!'

His blade glowed a clear blue as he swung it forward with a giant slash of blue lava going towards Gyutaro. Seeing this he immediately started spinning is arms causing blood to surround him.

Gyutaro: 'Blood Demon Art: Rampant Arceus of Evil!'

Blood surrounded him as the lava clashed with the slices with sparks flying creating an explosion. Gyutaro swiped the dust away looking at them.

Gyutaro: Niiice try there man, but it'll take more than that to defeat me. And it looks like you can't kick up the intensity of your attacks without any backlash.

He gestured to the burn on Ryu's hand.

Tanjiro: Are you okay?!!

Ryu: Ah this? Don't worry I've gotten burnt way worse. As for you big guy, you sure you don't feel like you're missing something?

Gyutaro seemed slightly confused before he realized his side was in searing pain and 35 percent of his body was gone. Taking the chance from the distracted Upper Moon, Ryu rushed forward and slashed his head off.

Ruby: Ryu what are you-

Ryu: We don't need to do it at the exact same time, we just have to make sure that they're both separated before the other can be reattached!!

He saw Tengen Inosuke and Zenitsu still fighting Daki on the back foot. He was about to move forward but stopped strained as he dropped to a knee.

Ryu: Damn! The backlash is no joke! Ruby, end it now!!

Ruby saw Ryu unable to attack and realized she was too far.

Ruby: 'Only one move then...'

An image of Rengoku went off in her mind as Rose Petals began to fly off of her.

Ruby: 'Just like Kyojuro. Set My Heart Ablaze.'

She got into a position as she burst into petals that were black and flaming.

Ruby: 'Flame Breathing: Esoteric Art!'

In an instant she closed the long gap between she and the others as she became tangible as Daki couldn't believe her eyes.

Ruby: 11th Form: Burned World!!

Faster than she could protect herself, Ruby slashed off Daki's head Grim Reaper style. Though this usually wouldn't cut due to the softness of Daki's neck, the speed in which she attacked happened much sooner than it could bend. Her he'd flew off and landed right in front of Gyutaro's.

Ryu: *Sigh* It's over.

He stood up cracking his neck.

Ryu: Though I'm not a big fan of having to injure myself every time I fight two of these guys.

Ryu clenched his burnt fist and saw the bodies begin to disintegrate. He also looked up hearing voices and saw that it was Tengen's wives crying from joy.

Ryu: I'll let them have this one.

He took in a breath before he began to walk to the others.

Ryu: Our work here's done.

They all seemed happy before shock filled them. Before any of the Slayers could say anything Ryu turned and blasted flames at the blood slices that tried to attack from Gyutaro's body while also destroying it in the process.

Ryu: HA!!! YOU WON'T BE ABLE TO GET UP EARLY ENOUGH TO GET THE DROP ON RYU MOTHER FUCKING KAIZEN!!!

Shojo: Uhhh, Ryu?

Ryu: 'Must you ruin everything? What is it?'

Shojo: Look on your shoulder.

Ryu looked and saw a slice there.

Ryu: -_- So much for not getting hit.

Tanjiro: RYU!!!

Tanjiro ran over to him terrified.

Tanjiro: W-We can fix this!! We can send a crow to Shinobu about the poison!!

Ryu: Tanjiro?

Tanjiro: N-No, too slow!!

Ryu: -_- Kid.

Tanjiro: Just hang in there, we can-

He was met with a punch on the top of the head falling down.

Ryu: I'm immune to poison Tanjiro, I'll be completely fine.

Tanjiro: O_O Huh?

Ryu: Poison. It doesn't work on me. Hell I can drink a barrel of it like water and only be sore the next day.

Tanjiro: That... Seems impossible to medically prove.

Ryu: That's what the doctors said.

He felt a tug on his pants leg looking down. He saw Nezuko was there healed and had gone back to normal but was still in child form with her bamboo back in her mouth.

Ryu: Oh, hey Nezuko.

She tried to reach Ryu's cut shoulder but failed seeing as at the moment he was two and a half feet taller than her.

Ryu: It's fine Nezuko. Look.

He pointed to the scratch as it seemed to be gone.

Ryu: Fine see?

Nezuko grew to a larger size and put her hand on the shoulder as pink flames surrounded Ryu.

Tanjiro: AHHHHH!!!!

Ryu: Uh, weird enough this doesn't-

Ryu felt an immediate change shocked before the flames disappeared.

Ryu: ... The poison's gone.

Tanjiro: What?!

Ryu: Huh, what a weird Blood Demon Art.

Tanjiro: That's what this is?!!

Ryu: Obviously. Thanks Nezuko.

He patted her on the head satisfying the small Demon girl.

Ryu: By the way, don't you need demon blood or something?

Tanjiro: OH THAT'S RIGHT!!

Tanjiro looked around for his knife but couldn't find it.

Ryu: Here.

Ryu handed it to Tanjiro seeing it was already filled with blood.

Tanjiro: When did you-

Ryu: Before the fight started.

Tanjiro: ... Is this what true speed is?

Ryu: Eh, it's just being sneaky.

They heard a meow as it was from the same cat. Tanjiro gave it the cat before it disappeared and left. That's when they heard arguing.

Ryu: Can they just die already?

They walked over seeing the heads arguing as they decomposed.

Ryu: *Sigh* Let's just leave.

Ryu was about to turn and leave before he heard something that just didn't sit right with him.

Daki: Ha, there's no way an unsightly thing like you could ever be my sibling!

That made him stop in his tracks and turn back marching to the heads.

Daki: WHAT DO YOU WANT?!!

She looked at the unimpressed look Ryu had as he crossed his arms.

Ryu: ... Do you genuinely believe that?

Gyutaro: THE HELL DO YOU KNOW?!!

Ryu: A lot actually.

Memories of his lives flashed before his eyes as the last image that appeared was of Amber.

Ryu: ... More than you'd know. You two are lucky to have lived together for centuries. Be grateful for that and die in peace.

Daki: DON'T LECTURE US!! GO AWAY YOU SHITTY BRAT!! GO SOMEWHERE ELSE!!

She began to cry once again.

Daki: THIS SUCKS THIS SUCKS!!! DO SOMETHING, BIG BROTHER!!!

After that her head had disappeared as well.

Gyutaro: UME!!!

Ryu hearing that was surprised before he got up.

Ryu: And that's my job done.

He got up as Gyutaro's head vanished as well.

Tanjiro: Do you think they made up?

Ryu: They're siblings, of course they did.

He sensed another presence knowing exactly who it was.

Ryu: Snake eyed mother fucker.

Walked over seeing Iguro over with Tengen and the others.

Ruby: What do you mean you won't allow Tengen to retire?!!

Iguro: Like I said, he can't. There are too many youngsters dying without showing any growth.

He felt his head being grabbed recognizing the grip.

Ryu: Problem?

Iguro: ... No.

Ryu: That's what I thought.

CHAPTER END!!
