{third POV}

"This way... I can smell most of the blood" Tanjiro told the group of pillars in a hushed tone, his own blood demon art ready on his arms and legs.

They cautiously followed behind, being careful not to get spiked by the spines on Tanjiro's limbs. They crept around a corner and instantly saw the piles of massacred bodies littering the floor.

Tanjiro gasped silently and pinched his nose shut, his eyes laying sight of Haruki laying limply decide a wall. The demon jumped out of his hiding spot and out into the open, gently picking up the male's body and cradling it in his own.

"H-Haruki... hey wake up you're fine come on" he whispered in disbelief, eyes beginning to well with tears as he shook Haruki's body but to no avail.

"Tanjiro..." a sinister voice hissed, making him freeze in place.

That's when Tanjiro remembered the flower. He gave it to Haruki to look after...

"Shit shit" Tanjiro began to curse himself as he placed Haruki gently on the floor and slowly turned to the demon king. He didn't blame Haruki for doing what he did, he blamed himself.

Muzan looked at Tanjiro with a smirk "look how powerful you are, come back to me Tanjiro."

"Shut up bastard! He's not a fucking toy" Obanai yelled, readying his sword as his snake coiled around the hilt. Tanjiro smiled at the male, standing next to the group of Hashira "you will die here Kibutsuji, I'll be sure of that...

You may be immune the sun, but I will kill you here. Mark my words" Tanjiro hissed, taking out his sword as the spines on his arms and legs got longer.

Everyone gasped "t-Tanjiro, what do you mean immune to the sun" Shinobu whispered from behind them, her tone holding hesitation.

"I'll explain later, I promise for now I just need you guys to weaken him to give me the chance to absorb him. Your blades won't kill him, this is our only hope"

Everyone looked at him sceptically but agreed anyways "I'll provide protection as well as offence. No one here will die except for him" Tanjiro stated, narrowing his glowing eyes.

Rengoku placed his hand on the demon's shoulder in a comforting manner "I love you Tanjiro, stay safe for our sake and we'll do the same"

His eyes widened at Rengoku's statement. He loved them all dearly, Tanjiro never had the confidence to confess his feelings... not to mention he was afraid if they would think he was an awful person to love more than one person.

But he couldn't help it.

Kibutsuji's eyes narrowed threateningly as he saw Tanjiro's cheeks tint lightly with blush at the pillar's statement.

"I'd like to see you try" Muzan hissed and roared, the skin on his back and legs ripping open for long bony like appendages to make way. He then transformed his arms into razor sharp blades and sent them hurdling into the group.

Each of the scattered at the long range attack and instantly got into place. They attacked him in a coordinated fashion, dodging his body appendages proving to be quite difficult in getting near him.

Tanjiro growled and thrusted his spikes into Muzan's tentacles which had been placed strategically around the area for a stent attack.

The flesh burned and turned a gross black sludge as Tanjiro's poison slowly seeped into the tentacle, making it completely useless.

A smirk crossed his lips "this is good news" he mumbled to himself and looked at the battle before him "oh... Gyomei, we could certainly use you right now" Tanjiro hummed, feeling the pillar's presence right behind him.

"Attack from the front by 35 degrees, that's his most unprotected spot" Tanjiro told the male before leaping into the action, swinging his sword in a circular motion as bright red fire surrounded his body.

Each one of Muzan's attacks were deflected as Tanjiro walked head on towards the demon king, the rest of the pillars still trying to get past his tentacles from behind.

"Come back Tanjiro!" Muzan screamed, relentlessly attacking him only for all his attacks to become futile.

Once close enough, Tanjiro harshly kicked Muzan's chest; only for a disgusting gaping mouth to open right in his stomach and crush his leg entirely. Tanjiro screamed and rose his hand in the air and cut his own foot off, swinging his sword erratically to cut both the demon king's arms off.

Muzan narrowed his eyes as a large metal ball connected painfully with his face, Gyomei standing and swinging the chain to stop him from getting closer to Tanjiro.

Muzan ripped out the ball and threw it into the wall, his mutilated face leaking pools of blood as he regrew his arms and looked down on Tanjiro.

"Stay with me Tan-"

"Shut it bitch!" Genya came crashing down on the demon, shooting him repeatedly in the chest while standing protectively above the boy.

"Just die already!" He screamed again, slicing off a nearby tentacle with his sword while continuing to shoot him. Tanjiro groaned and tackled Genya to the floor, putting his body on top of the male just as Muzan slashed his arm with the intent to kill.

Tanjiro gasped as his whole back was cut open, making eye contact with Genya underneath him as his own blood dripped onto the taller male. Genya I
watched horrified as Tanjiro's whole body was cut in half with another slash, the two half's of his body falling to the floor.

Genya cradled the boy's upper body and prepared for another attack but it never came "leave him Alone you brute!" None other than Mitsuri yelled, tears streaming down her face as she took all of the attacks while protecting the two.

"G-Genya" Tanjiro forced out as his lower body started to regrow "tanjiro! Yes I'm here" the male panicked, holding his body through teary eyes.

"Don't cry love, I'll protect you" he mumbled with a shaky smile, how legs now regrown up to to his knees "y-you've got to look after yourself!" Genya cried, his own tears dripping onto the demon's cheeks.

"I'll be fine, here. This'll help your demonic transformation" Tanjiro ripped out a piece of his burgundy hair and gave it to Genya, to which the slayer unwillingly swallowed the DNA; his fangs immediately grew as the his eyes seeped into a deep black.

Suddenly Tanjiro snapped back into action again, leaping off Genya's lap once he fully Regenerated and catching Mitsuri just before she hit the ground. Her chest had a deep gash in it, horrific amounts of crimson pooling her clothes.

Tanjiro's eyes widened as he gritted his teeth and grew his blood red wings using one of the now deceased upper moon's art and sweeping both Genya and Mitsuri in his arms.

Tanjiro flew to a safe place and quickly ripped his Haori off as everyone else occupied Muzan for the time being.

"Quickly stop her bleeding" Tanjiro ordered Genya and flew off leaving the two in the safe space before quickly assessing the battle again. He landed on the floor with a crash, large wings flared menacingly behind him.

Tanjiro growled and cut through Muzan's bony appendages using his sword, just saving Rengoku from getting his arm cut off.

"Thanks kamado" he panted, slumping his shoulders from fatigue. Tanjiro patted Rengoku on the back, wrapping his wing around the male in a comforting manner "I'll leave an opening for you, press the attacks to weaken him ok? I'll give you a signal when"

Rengoku nodded his head and started to spread the word to Gyomei, Shinobu and Obanai.

"CAW CAW 10 MINUTES TILL SUNRISE"

Tanjiro smirked, flexing his claws in a threatening manner as he flew into the sky; curling his wings behind him and descending to the floor at a terrifying speed. Tanjiro pointed his sword directly downwards, catching Muzan off guard and impaling him straight through the skull.

Tanjiro crashed to the floor as the top of his sword imbedded into the broken ground, Muzan being forced to the ground as his sword pinned Muzan's head to the ground.

"Now!" Tanjiro screamed, pushing down on the hilt with all his might as he used his wings to put more pressure on it. Suddenly the hashira started to bombard him with every attack possible.

Suddenly more Hashira turned up at the scene, just in time as well.

Tengen, Giyuu and Muichiro looked at it with wide eyes before going to help, the water and mist going to help the others as Uzui jumped to help Tanjiro keep the sword imbedded through his skull.

Tanjiro's eyes widened gratefully at the backup, his face brightening before his hope was extinguished in a second.

Muzan firmly punched his fists into the concrete, using it as stability to thrust his torso up and rip Tanjiro's sword out of his head. The demon roared and regenerated all his cut off limbs and threw every hashira off him.

Kibutsuji lunged quickly for Tengen, however Tanjiro threw the pillar out of the way just in time; Muzan's hand now wrapping around Tanjiro's neck in a steel grip.

Everyone gasped and stilled their movements, taking the advantage to catch their breaths.

Tanjiro flailed in his grip, wings flapping frantically behind him as Muzan dug his nails into the boy's neck.

"No one fucking move"
