The Last Night

It was a quiet night on Mount Natagumo – the home of the Spider Demons. Not long ago, a battle took place, between the Demon Slayers and the Spider Demons. All of the Spider Demons have been defeated, with just one remaining…

"Huh…?" Spider Sister mumbled as she woke up

Looking around, she saw her familiar environment, the Natagumo Mountain. Confused as to what happened, she tried to move, but couldn't. Looking down, she realized that she was tied down to a tree.

"What the…?!" she said angrily as she tried to break the rope and set herself free

She was a demon, so breaking a simple rope wouldn't be something hard, but for some reason, she couldn't do it.

"GRRR!" she grinded her teeth as she struggled

As she was trying to break the rope, a voice interrupted her.

"You can stop, you won't break it."

She turned her head and saw a Demon Slayer, sitting on the ground, watching her. He was wearing the standard uniform, as he was sitting and watching her.

"That's a special anti-demon rope. No demon can break it." he explained, with a plain expression

Spider Sister looked at him confused and ignored his words, trying to break the rope again.

"GRRR!" she grinded her teeth again as she tried to break it again, but it was futile

After a few seconds of trying, she gave up and looked at the slayer.

"You done now? Good." the slayer said as he noticed that she stopped

"Why did you tie me down?! What do you want?!" she asked angrily

"To watch you." he replied

"What?! Watch me?!" she snapped at him

"It was you, wasn't it? You were to one who attacked and killed my friends... Always from the back… always when they were alone… like a coward…" he said in a calm voice and a blank expression

"…" Spider Sister didn't say anything, just looked at him nervously

"Why did he tie me down… what does he want? Is he… going to torture me!?" she thought to herself

"So… now we are here." he continued as he watched her

"L-let me go! My family will be here any second and they will kill you for this! B-but… if you untie me… I might let you go." she said, as she tried to talk her way out

"Sure they will." he replied and watched her, but didn't do anything

"You don't believe me?! You will die if you don't untie me now!" she screamed

"…" he just leaned back and continued watching her reaction

After not getting a response, Spider Sister began screaming even louder.

"YOU STUPID BASTARD! LET ME GO NOW!"

"…" still silence from him, as he was watching her with a blank expression

"GRRRRRR!" she grinded her teeth again and began struggling, trying to break free with all of her force

After a while of trying to break the rope, she gave up again. The whole time, the slayer just watched her and didn't say anything.

Trying to catch her breath, Spider Sister looked at him.

"So what now!? Huh?! This is your plan?! Just watching me?!" she asked, trying to buy herself time for someone from her family to come

"Yes. And listening to what you have to say." he explained

"And how long will you do this, huh?!" she asked angrily

He looked at sky and replied.

"Well… the sun comes out in around 1 hour..."

As she heard that, the anger in her face left her in an instant and she became pale.

"The… sun… ?" she mumbled, with fear in her voice

The slayer nodded and watched her start to panic.

"Y-you can't be serious…" she said with a soft voice

He just watched her.

"W-wait! I'm sorry for your friends! B-but I was ordered to do that! I didn't have a choice! I would have been killed if I didn't follow my orders!" she panicked

"…" he didn't say anything, just watched her with a blank expression

"IT'S TRUE! I'M TELLING YOU THE TRUTH! PLEASE DON'T DO THIS! PLEASE!" she screamed now, as panicked

"…" still silence from the slayer

"R-RUI! MOTHER! FATHER! SOMEBODY HELP ME!" she screamed for help

"Nobody will come to save you." he explained

"RUI! RUI! HELP!" she screamed and frantically looked around

"Nobody will come, because you're the last demon here." he explained again

"YOU'RE LYING! No way in hell did you lowlifes defeat Rui!" she countered

"…" he didn't say anything

As Spider Sister panicked, she noticed something odd. Her body felt weird. Normally, she could fell Rui´s threads all over her body, controlling her and making sure she obeyed his orders. But now, they were all gone.

"N-no…" mumbled Spider Sister as she realized, that the threads were gone, meaning Rui was indeed, dead

"Ah… ah… NOOO! PLEASE!" she screamed and started to cry, as she realized that nobody would come to save her

"… "

"WAAAHHHH! NO! PLEASE! NO!" she cried, screamed and begged

After a few minutes and crying and sobbing, the slayer spoke.

"You're pathetic, you know that?" he said with no emotion

Spider Sister raised her head and tried to look at him through her tears.

"You murder my friends without mercy… and now cry like a small child…" he said

"SOB* SOB* P-please… spare me… I'm sorry… SOB*" she mumbled

"…" he was silent again and looked at the sky, realizing that the sun comes out in a couple of minutes

He looked back at her again and continued watching.

"I don't… SOB* want to die… SOB* P-please…" she mumbled, as tears were pouring out of her eyes

After a few minutes, the sun was coming up, with the light coming closer.

"No… no…" Spider Sister cried as she knew, that her death is coming closer each second

"I can't show you mercy. Not after what you did to my friends… but…" he said as he got up

"I hope, that you get a second chance… in the next life." he said as he walked up to her and looked her in the eyes

"SOB* SOB*" she cried

After a few seconds, the sunlight finally reached them and the demon began to burn.

"NO! NO! NOOOOOOAAAAAAAAAHHHHHHHHHHhhhhhhhhhh…!" she screamed, as she died a slow and painful death

"Goodbye…" the slayer said and watched her burn, getting revenge for his friends

After a few seconds, she became quiet, and her body burned up and disappeared… leaving only her burned clothes and pears from her hair behind.

The slayer walked over to her remains.

"Next life… I hope things work out differently, and we can become friends." he mumbled as he turned around and left

And with this, all the demons on Natagumo Mountain were gone…
