End or arc 2

"Did we win" an unknown shinobi raised his voice in confusion.

What happened before everyone's eyes like a dream. A sweat dream that they longed for.

Muzan, the first demon and also their long enemy, was dead like this. And also, a stranger interfered in middle of battle out of nowhere finishing him like a god.

They were all stunned by the result of the battle.

Cast it aside, that doesn't prevent them from celebration.

"We won."

"We did. We won."

"No more demon in the world."

"Hey, where did that guy go?"

The person who contributed most wasn't presented now.

"I thought he lost conscious. How come he walk away in that state."

The main protagonist of the show was disappeared.

"Oh. He disappeared."

Meanwhile

In the world of conscious.

"You will inherit my will, Jean." Muzan held Jean's conscious as if she was his last hope.

"Become a demon that won't afraid by sun light."

Muzan touched Jean's soul with intention that he will overwrite his will over Jean's will. By doing this, he can be reborn as new identity.

His hand reached out for Jean's soul. Suddenly, there was another hand grabbing his hand.

"Don't do that in front of my eyes." a unfamiliar voice rang out.

He turned his head and saw a guy with numerous number 0 and 1 on its body.

"Who are you."

"I'm her system."

"What are you saying?"

"My race is system. As for my name, it's a secret"

"I don't ask you that. I ask you why you are being here."

"That's so mean. I try to be polite."

Muzan glared with a pair of beast like eyes.

"You're going to kill me with those eyes. Good luck with that."

Feeling annoyed by its words, Muzan charged without thinking.

The surrounding him turned into dark theme boosting his menace. Being beaten by those ants already pissed him off. Now, there is something that out of his understanding also pissed him off.

He grabbed its head ripping off its arms, legs rendering its immobile.

"Now, do you dare to talk with me in that attitude."

Although he can't see its mouth, he still felt that it was laughing at him. As if he was an ant in its eyes.

"Sweat dream. Demon lord" Behind him rang out a voice.

He turned around and saw a big screen floating.

"Time to wake up"

"With your experience pity like that, you think you can kill me. I don't know you are stupid or brave or both."

Muzan, for a first time, felt a true fear in him.

"Let me teach you. The proper way to eliminate."

"No. I don't want to" without listening his last words, system turned him into ash in a second.

"Seriously, this is the first time I see a remnant of will dare to threaten me."

"Whatever. After this, my host will have a peaceful journey from now. So which world I will go next" opening a star map, system searched for a planet having the most valuable and shortest path.

….

The battle ended triumphantly. Muzan death marked the new age.

The remnant of demon was hunted down by demon corp. The demon corp purged and killed leaving no demon on the world.

Also, this broke the curse of Ubuyashiki Family. However, this didn't cure the disease that Kagaya lord who held the rage towards Muzan many tears.

In the end, he passed away in smile after hearing the feat of his demon corp.

Some demon hunters celebrated for their victory. Some can't reach this end but their sacrifice wasn't waste and forgotten at first place.

The battle of demon and human came to end.

200 years later.

"A battle that no one know. Even the generation of demon corp also forgot what their ancestor do."

I looked at Kagaya lord who supported me most in the past. I laid gently blue flowers on his tomb.

After years of finding, I finally found the flower that Muzan longed for.

Blue spider Lily.

"I feel pathetic for Muzan."

When I visited Tanjiro's home. Home where his brothers, sisters and mother died by Muzan's hand.

At that place, this flower bloomed under the sun light on their tombs.

Who knew behind Tanjiro's house is a forest of Blue spider Lily.

And this thing only bloom at day. No wonder why Muzan never found it.

"System. Time to go." I stood up and dusted the clothes.

"Yeah. Give me a second."

I looked far way. I could see the young generation of demon corp happily walking together on same street.

"As if this is a fate."

They are strong, happy and cheerful. Their ancestor did something incredibly and they don't know it. Even though there was some records in their house.

"Maybe this is a good way"

Demon is a existence that shouldn't be known to human.

"3 … 2 …1. And here we go."
