Sayuri was throwing caution to the wind.
She needed to let off steam.
Like post-traumatic stress. The difficult process of slowly killing the Demon was also a huge psychological shock for Sayuri.
That's why she wanted to take a thorough bath.
Even though she was as clean as she could possibly be, the urge to bathe just wouldn't subside.
And...
Because she needed to vent, she invited Kaito to help.
Yes!
She wasn't backing down!
She was choosing to face this head-on.
Bring it on!
It was something she'd have to face eventually anyway!
"Oh? Are you sure?"
"Hmph, unless you're willing to let me die."
Sayuri, half shy and half angry, looked at Kaito's mischievous smile and couldn't help but give him a little punch.
"Haha, of course not. Alright, let's head back. We still have one more place to go."
"Mm... mm!"
Returning to the rock platform, the others hadn't really seen Sayuri's Demon-killing process clearly.
After all, it was...
Too torturous to watch.
Sayuri was an ordinary person, and that Demon's body had been enhanced, which was why the Nichirin Blade couldn't penetrate.
She had to keep swinging.
So...
Many had watched only half the process before retreating, observing the rest from a slightly farther distance.
Naturally, after watching, they also felt uncomfortable.
Everyone did, even Misuzu and Mikoto.
For the fourth Demon, it was Tanjiro's turn.
He also used an ordinary Nichirin Blade provided by Kaito. Gritting his teeth, showing the completely insane female Demon a look of pity and anger, he killed it cleanly with a single stroke.
"Rest in peace... I will avenge you..."
After crouching down and speaking to the female Demon, Tanjiro slowly sheathed his blade. Only after the female Demon's figure had completely vanished did he stand up, taking deep breaths to calm his inner turmoil.
"Sigh... Kaito-nii, I did it. I killed her in one strike..."
"Mm, you did well."
Patting Tanjiro's shoulder, Kaito expressed his satisfaction with Tanjiro's performance without any surprise.
This was Tanjiro. Even if the enemy was a Demon, he would still feel pity and sympathy, but that wouldn't stop him.
Granting them a swift release was what he truly needed to do.
Trying to find a way to turn them back into humans on the spot, or convincing them to endure until he killed the Demon King, was completely unrealistic.
"Huh? Someone is chasing the fifth Demon?"
As he prepared to control the platform to the next destination, Kaito paused.
Because that red dot was moving very fast, fleeing towards a mountainous area, as if hiding from someone.
After sensing more carefully, he soon perceived a girl of not very tall stature chasing the Demon.
So, a girl of not very tall stature, part of the Demon Slayer Corps… who could this be?
Kaito focused his observation, quickly simulating her physical data and gradually generating a human image in his mind.
'Huh...'
'What a coincidence!'
It was truly a coincidence!!
Kaito had no idea why she was here either. But since she appeared, there was no reason not to meet her.
"Tanjiro, maybe you'll get to see how the Demon Slayer Corps kills Demons, and also witness what the Breathing Techniques I mentioned are capable of."
"Huh? Really?"
"Hehe, the fifth Demon is currently being chased by a member of the Demon Slayer Corps."
With a slight smile, everyone around grew curious.
After maneuvering the rock platform towards the destination, they soon arrived at a mountainside.
Looking from above, they couldn't see anything, as it was pitch black at night.
Besides, it was obscured by the dense trees.
But no problem!
Kaito used magic to create a magical mirror, quickly capturing the scene below.
Actually, he could have used this magic back at their original location, but he wanted to meet her.
Soon enough!
In the mirror, a girl with a strange-looking Nichirin Blade appeared, chasing a panicked Demon.
This blade piqued everyone's curiosity, 'Was such a thing still a sword?'
It looked like a katana, but from the hilt to near the tip, there was no blade… only a spine, like a thin rapier.
Only the tip of the rapier had an edge, like a barb.
As for its sheath, it was white, while the blade, guard, and hilt were mint green. The guard was four-lobed, which wasn't too strange.
After all, good blades didn't have to be uniformly shiny silver like steel knives.
"I never expected a young girl from your world, Mrs. Kamado, to possess such combat strength."
Sayuri couldn't help but exclaim.
This girl was shorter than her. Although she wore the Demon Slayer Corps' uniform with a haori patterned with butterfly wings, as a woman, Sayuri could tell at a glance that the girl's figure was rather slender.
It was just...
Damn!!!
Sayuri inwardly seethed.
'Why was this delicate-looking girl bigger than mine!!'
Of course, she was also impressed by the girl's rapid movement ability.
She moved like a ninja, darting between the trees, landing steadily on a branch before leaping again. Repeating this, she eventually cornered the Demon.
Then, after the girl seemed to do something, flower petals appeared around her. Transforming into butterflies, they covered the Demon. With a light stab of her blade, the girl stood before the Demon.
"Oh dear, you made me chase you quite a bit. Why did you run?"
The girl said this to the Demon. The butterflies on the Demon slowly faded, revealing a face even more ferocious, with bloodshot eyes that seemed about to pop out.
Finally, the Demon died from the potent poison and began to self-immolate, disappearing.
Swish...
The battle over, the girl sheathed her blade after watching the Demon die. Looking around, she wore a troubled expression.
She seemed... lost?
Well, no big deal. A quick jump onto a tree would show her the best path down the mountain.
"Tanjiro, did you see that? This is what combat between the Demon Slayer Corps and Demons looks like."
"Uh... Kaito-nii, it seems different from what I imagined?"
"Haha! That's just because each member of the Demon Slayer Corps has their own fighting style."
Patting Tanjiro's shoulder, Kaito actively lowered the platform and dispelled the cloaking magic.
Just in time, the girl jumped onto a tree branch and looked up, seeing the flying rock platform.
"Good evening, Kocho Shinobu!"
