The new demon king (Completed)

The devastation.

AN: Hello my fellow readers! I am just here to make a small message of saying  thank you for all the support you provided. I am truly glad you enjoy these fanfictions I am writing! I will try to make the chapters longer that 1000-2000 words because that's very underwhelming  for me.

As I said I will make an official vote on what you want for the next fanfiction. I will be making ships in my fanfictions after this! But keep in mind: NO HAREMS! (if I find one suggestion of a bloody harem its getting shot down right away)

--------------------------------------------------------------------------------------------------------------------------------

And so, here we are. The final battle, the battle that will determine the fate of humanity. Will the humans live? Or will they fall? 

Their fate lies on the hands of Kamado Nezuko, her friends, and her hashiras. Should they be victorious, then it is  fated that humans will survive, but will she be able to kill her own brother? Only one way to find out. 

As of now, Tanjiro was like a one man army. Him alone wiped out almost half of the military, all by himself, and he wasn't even remotely tired, he stands strong. The boy who once carried a pure heart and soul now was gone, all corrupted by the first king of the demons. 

But put all these thoughts aside, for we have a war ongoing  as of now. 

The massive skeletons that Tanjiro created with his blood demon art makes a loud roaring noise and bends down and slams their hand onto a hashira but it picked the wrong pillar. It was Gyomei, with his bare hands he stopped the hand from even crashing down by holding it up, he roars as he uses his strength and pushes the bony hand off.  (Strongest hashira, literally) 

His stunt made everyone's jaws drop to the floor, even Tanjiro who saw his strength scared him. But that wasn't the only surprise, he turns to see Mitsuri going to the left with her whip like sword and she wraps it around the Giant skeletons hand and cuts it into little pieces. 

He sends one of his bony tentacles towards her only for her to grab it with her bare hands and with her wrath and her own two hands, she pulls the entire tentacle off of him ripping it from him. This also shocked everyone except for Gyomei and Obanai, who cheered for her yelling in his mind: 'THATS MY GIRL! AIN'T NOBODY TAKING HER AWAY FROM ME!!'

Tanjiro on the other hand 'Holy hell what the hell has she been eating?! Obanai got himself a good girlfriend.' was his only thought. His thoughts were stopped when he sees a flail flying towards him, he draws his katana out and deflects it back. 

Gyomei began spinning his flail and axe at a rapid pace "Breath of stone, Second Form: Upper Smash" he throws both his axe and spiked flail for a pincer move before smashing down on the chain to cause the flail to then rebound and smash his target from afar. 

Tanjiro's eyes widen as he deflects back the axe but avoids the flail, it was merely a distraction as he sees the flail move from the ground and Gyomei was now a lot closer to him, for a man his size, he moves faster than most. 

"Breath of stone Fifth Form: Arcs of Justice" The user utilizes a powerful barrage with his flail and axe, doing a great amount of damage. The axe is destined to hit first with the trajectory of the flail following from the opposite side and slamming into the opponent. 

However a Massive skeletal hand crashes in front of him, protecting  Tanjiro. But the Hashira came prepared as he changes his target, using the momentum of the form he used, he moved faster and used the barrage of attacks on the hand of the Skeleton destroying the hand completely. The gashadokuro roars in pain as Gyomei runs up on its arm. Moving fast so he  doesn't fall off.
