At the headquarters of the Demon Slayer Corps—
When Sanemi Shinazugawa regained consciousness, he found himself back in the familiar courtyard.
After exchanging glances with the other Hashira, and briefly looking at Tanjiro Kamado and Nezuko Kamado, he finally turned to Kagaya Ubuyashiki.
"Master, I've returned!"
"Welcome back. Did you discover anything?"
"Yes, Master. Inside that place… it's a replica of Mount Natagumo created by some unknown existence."
"You fight alongside warriors from other worlds."
"And the enemies are the Spider Family—the Twelve Kizuki from that mountain."
"After defeating them, you receive rewards."
"Each person's reward is different. It seems to be random."
"My teammates received Scarlet Crimson Iron Sand and Breathing Techniques."
"Oh—and there was one extremely powerful teammate who obtained a legendary item…"
Sanemi paused slightly.
"Blue Spider Lily."
"Master… have you ever heard of such a thing?"
Kagaya shook his head gently.
"No. But I will have someone investigate it."
"Since the rewards given are all related to the Demon Slayer Corps… that Blue Spider Lily likely has a deep connection to us as well."
However—
What Kagaya could not see…
Was that Sanemi's expression had turned extremely ugly the moment he said "the rewards are all items of the Demon Slayer Corps."
The others, however, saw it clearly.
His close friend Obanai Iguro frowned slightly.
"Sanemi, why do you look so troubled? Did something bad happen in there?"
"N-No… nothing…"
Sanemi stammered, shaking his head.
At that moment—
Mitsuri Kanroji suddenly asked curiously:
"By the way, Shinazugawa-san, you haven't told us what reward you got yet!"
Sanemi's body stiffened instantly.
Subconsciously, he clutched the front of his chest tighter.
But that only made things worse.
Everyone's gaze immediately focused on his chest.
Tengen Uzui pointed at him.
"Sanemi, is that your flashy reward from the instance? What is it? Show us!"
"It's nothing! I'm going to destroy it anyway! There's nothing to see!"
Sanemi stepped back, gripping his clothes tightly.
But someone moved faster.
Giyu Tomioka stepped forward.
In a flash—
His hand slipped into Sanemi's clothes.
When it came out—
A bronze box was already in his grasp.
"You—!!!"
Sanemi's expression twisted violently.
His hand immediately went to the hilt of his Nichirin Blade.
Only the intervention of Gyomei Himejima—the strongest Hashira—prevented bloodshed.
Curious, Mitsuri took the box from Giyu and opened it.
"KYAAAHHHHHH!!!"
Her scream echoed across the entire courtyard.
Snap!
Before anyone else could see—
She slammed the box shut, her face completely red, and threw it back at Giyu.
"How could you show something like that to a girl?!"
Obanai instantly appeared beside her, pulling her into his arms protectively.
"Giyu! What did you show Mitsuri?!"
He slashed at the box with his uniquely shaped blade.
Giyu blinked blankly.
"…It's not mine."
Meanwhile—
The true owner, Sanemi, let out a desperate scream:
"NOOOOOOO!!!"
Clatter!
Click!
The box fell to the ground.
The mechanism popped open.
Inside—
A pristine white piece of women's clothing, decorated with spiderweb patterns.

Silence.
Absolute, suffocating silence.
After a long pause—
Kagaya's voice broke it.
"…What was in Sanemi's box? Why has everyone gone quiet?"
Beside him, Gyomei also perked up slightly, listening carefully.
Being unable to see—
Made moments like this especially frustrating.
"A… it was a—"
Before the white-haired girl could finish—
"DON'T LET THAT FILTH POLLUTE THE MASTER'S EARS!!!"
Sanemi roared, cutting her off.
Kagaya paused briefly.
Then understood.
This must be something Sanemi couldn't speak of.
So he gently changed the topic.
"Since Sanemi has already investigated this strange space and found no major danger…"
"The remaining exploration will be entrusted to you, the Hashira."
"Once safety is confirmed…"
"You may bring your Tsuguko and corps members in as well."
"It will help them gain experience fighting the Twelve Kizuki."
"That is all. You are dismissed."
With that—
Kagaya was supported back inside by his daughters.
The Hashira knelt until he disappeared from sight.
Then rose and left one by one.
Tanjiro and Nezuko were carried away by Kakushi members—
Following Shinobu to the Butterfly Estate for treatment.
A week passed.
During that week—
Countless people across countless worlds entered the instance.
Some won and obtained rewards.
Some failed repeatedly—never winning even once.
Some got carried by overpowered teammates.
Others relied on skill and teamwork to clear it.
Meanwhile—
The demons sent by Muzan Kibutsuji, while grinding the instance—
Saw the announcement that someone had obtained the Blue Spider Lily.
After reporting it—
All demons—
From newly turned ones…
To even the Twelve Kizuki—
Spent the entire week farming Mount Natagumo.
But—
No one ever obtained the Blue Spider Lily again.
As for Guanyin Dashi—
After returning to his world—
He simply thought the flower looked rare…
And casually gifted it to his friend, Jizo.
If Muzan wanted to take it back…
He was welcome to try.
Over the week—
Many people from different worlds became acquainted through the instance.
After fighting together—
If they got along well, they would add each other as friends.
And when free—
They would communicate through the small glowing screens.
Finally—
After a full week of waiting—
The sky lit up once more.
New words appeared on the massive screen.
Countless viewers—
Who had been waiting eagerly—
Held their breath.
