Humanity vs Demons? Who shall prevail?[2]

Why hello everyone, this would be my final entry for this prompt. However, instead of continuing from my previous entries like before. I had a much better idea, why not go out with a big bang.

#TeamHashira

Meanwhile in the middle of Marley Liberio Hospital.

Eren would've been in Marley for awhile. He gotten letters from his brother of an War. Over the years, the two would talk about plan of Euthanasia. So for now, Eren was going undercover in the first place.

"Quite a marvelous day it is."

"It sure is."

Eren was interrupted by a tall man sitting next to him onto the bench. Having a fan covering his face while only chuckling uncontrollably.

"My my, I never seen you here before. Though you look quite threatening. So what is your name?"

The man said closing the face to expose his face along with his beauty eyes that had the mark of "Upper 2"

"Eren Kruger, you?"

"Douma. What's little old you doing here in this hospital? Surely you look like you don't belong here at all."

Eren would've ignored Douma's question. He didn't want to be bothered as though he had other things on his mind. From Douma's appearance outfit wise, it was much different.

"Reasons"

"I SEEE! Not the talkative time you're, aren't you? Either way. I might as well spill on what I'm doing!"

Douma then cleared his throat.

"I Douma am here to expand my cult. However, not much luck here in general."

"Pathetic..."

Douma heard Eren's response, as he got extremely close to Eren. Destroying any personal space that he had.

"Nothing, forget about it."

"That's what I thought. Anyway, I must go because this place is quite boring. Might as well grab a snack along the way.''

Douma then got up from the bench and stretched his back a bit.

"See ya."

Eren said paying no mind to Douma leaving.

"You should smile more or wave, don't try to destroy the world."

Douma then waves his hand goodbye as though just like that. He was gone.

"What a strange guy..."

Eren said as he had enough for one day and just waited for Zeke to arrive.

Back on Paradis, Tanjiro was in a deadly fight with UpperMoon 6 Rank Daki. He was sentenced to the island with high reports of Demon.However, he wasn't alone in this fight. He had his sister Nezuko in the box. Earlier, he was paired with Tengen but got lost. Hencing he got ambushed by Daki.

Tanjiro was backed against the tree as Daki row of sharp like ribbons were heading towards him. To much for him to even dodge or counter. Yet he still had.

"HINOKAMI KAGURA."

Into a matter of seconds, a flame would've emerged from his sword. Daki was rather surprised from seeing an attack especially such close in the first place. However, as most of the ribbons were burned from the flames. A ribbon on the side would've hit against Tanjiro's left shoulder. Blood was drawn as he was cut on that shoulder.

"MHM!"

Tanjiro grunted in pain as though someone else was awaken from the box. Nezuko was awakened. Out of the box, she came. Her form was much larger psychically appearance wised.

Into a matter of seconds, Daki was kicked back into the tree. There stood Nezuko full of anger as the bambo in her mouth snapped.

"YOU LITTLE SH-"

Daki was cutoff from Nezuko, who quickly had her foot aggressively kicking Daki's head against the tree.

"OUCH!"

"THEY CAN NEVER COME BACK! Why do you rob those? Why would you trample over their lives?"

Tanjiro was referring to the words of the lives Daki took. However, Daki took their in total shock. Words that were familiar but from where? When it hit her. Infront of her was a twll man wearing a red haori on his shoulders. The cold wind blowing against his hair.

"What do you find so entertaining? What's so amusing about this? What do you take life for, exactly? How can you forget?"

The most powerful man in all of history was heading towards her with his sword out.

"I'M AFRAID!"

It wasn't Daki's voice but rather in fact of Muzan. To this day, Muzan was still afraid to that very man. Yoriichi...

Daki heart would've begin to race as he saw Tanjiro was getting closer with the same flames from before.

"BIG BROTHER, COME HELP ME!"

Out of nowhere, a large figure came out of Daki's back. Nezuko's right was grabbed as though he then throwed her against the tree.

"NEZUKO!"

Tanjiro looked over at her thrown at the tree. However, his attack was blocked by two scythes in his hands. This was Daki's older brother, Gyutaro who was also an UpperMoon 5 but much stronger.

However, Gyutaro wasn't alone at all. Out of the bush behind Tanjiro, a muscular man with a presence that was much stronger than Gyutaro and Daki combined. The demon that came out of nowhere wasn't the first time he met with him.

This was Akaza. UpperMoon Rank 3. The last two met was back at Mugen Train. The death of the Flame Hashira, Rengoku. Tanjiro never forgot that moment.

"I told you, the next time I saw your face kid. I'm going to kill you."

With Nezuko trying to recover, Tanjiro was outnumbered by both Daki and Gyutaro along with Akaza. As Akaza was about to charge.

"DIE KID!"

Out of nowhere two soliders with striking blades would've clashed. The two strongest soldiers, Levi Ackerman and Mikasa Ackerman ed the fight.

Daki quickly jumped back trying to gain some distance. She was confused as both two Ackermans entering the fight. Both were infront protecting Tanjiro.

"W-Who are you?"

Tanjiro said looking up at the two but he was grateful for being saved.

"Levi Ackerman and this is Mikasa Ackerman."

Mikasa was holding her blade as though she would've quickly charged at Daki as then Gyutaro then clashed back at Mikasa's sword.

"BRING IT ON! YOUR ALL WEAK!"

As Akaza and Levi then quickly clashed back and forth. With fists and swords clashing against each other. At the same time, Nezuko awakened and then quickly ed the fight.

However, as Levi's blade and Akaza's fist was clashed. A single sword slash quickly sliced one of Akaza's hand and broke Levi's sword.

"Hmmm?"

"Akaza. What have I told about learning respect. I been here the entire time."

A threatening aura. Stronger than anyone here or even the island. Stood a tall man with that has a sword onto his side. A demon he was. UpperMoon Rank 1. Kokushibo was here as his 6 eyes were focused into the battle.

A force to be reckoned with. Not even the strength of the Ackermans could match up against him. One one side had the powerful UpperMoon Demons while the other had Tanjiro along with Nezuko and both Ackermans. A fight that will determined who is victorious.

THE ALMIGHTY KOKUSHIBO S THE FIGHT!!

WHO WOULD WIN? HUMANITY OR DEMONS?

To be continued....
