Meiji 41 (1908) — Demon Slayer Headquarters
The Hashira Meeting Hall was unusually full.
Not loud—never loud—but charged.
Stone pillars framed the room like witnesses. Wisteria incense burned softly, a reminder that even safety here was borrowed.
Ubuyashiki Kagaya sat at the head, pale hands folded, smile gentle and unchanging.
Around him:
Gyomei Himejima — Stone
Giyu Tomioka — Water
Tengen Uzui — Sound
Sanemi Shinazugawa — Wind
Kanae Kocho — Flower
Mitsuri Kanroji — Love
Kai — Sun
Titles had settled.
Now came consequences.

Kanae Steps Forward
Kanae bowed first, graceful and calm.
"I would like to propose the establishment of a dedicated facility," she said.
"A place not for combat—but for recovery."
Shinobu stood beside her, arms folded, eyes sharp.
"A permanent estate," Kanae continued, "for wounded slayers. A space for healing, rest, and medical study."
Shinobu picked up seamlessly.
"Currently, injured slayers are either sent home—where they often die quietly—or rushed back into battle half-healed," she said flatly.
"This is inefficient. Cruel. And wasteful."
Sanemi clicked his tongue. "You saying we're throwing people away?"
"I'm saying," Shinobu replied sweetly, "that the Corps survives despite its habits—not because of them."
Tengen laughed. "Ooooh, that stung. I like her already."
Kanae smiled faintly.
"The estate would be maintained with wisteria," she added.
"Safe. Hidden. Staffed by trained attendants. Shinobu would oversee research into poisons, antidotes, and faster recovery methods."
Gyomei pressed his palms together. Tears slipped freely.
"Lives saved… after battle," he murmured. "A sanctuary. This is… righteous."
Giyu nodded once. "Necessary."
Sanemi exhaled sharply. "…Tch. Fine. If it keeps idiots alive longer."
Mitsuri's eyes sparkled. "A healing home! That's wonderful!"
All eyes turned to Kagaya.
He was smiling more brightly now.
"A Butterfly Estate," he said softly. "A place where wings may rest before flying again."
Kanae bowed deeply.
Shinobu looked away, cheeks faintly pink.
"It will be done," Kagaya said. "With my full support."

Then—Kai
Kai had been silent the entire time.
When he stepped forward, the room stilled.
"My proposal concerns lower-ranked slayers," he said calmly.
Sanemi's brow furrowed immediately. "Here we go…"
Kai did not react.
"Most deaths occur before slayers ever reach Breathing mastery," he continued.
"Not due to lack of courage—but lack of tools."
He placed a small wrapped bundle on the floor and unfolded it.
A compact firearm—simple, rugged.
Shinobu's eyes sharpened instantly.
"Guns," Sanemi scoffed. "You're kidding."
"Customized ammunition," Kai corrected.
"Low-caliber. Short range. Fired with wisteria-based poison rounds."
A ripple went through the room.
Gyomei inhaled slowly.
Giyu's eyes narrowed—not in disapproval, but calculation.
"They are not meant to kill outright," Kai said.
"They are meant to create openings. Slow demons. Buy time. Reduce panic."
Tengen leaned forward, intrigued. "Flashy adaptation."
Sanemi scowled. "Breathing styles are tradition."
"And traditions are burying children," Kai replied quietly.
The words landed heavy.
Shinobu stepped closer to examine the weapon.
"…With the right toxin concentration," she muttered, "this could paralyze a demon for several seconds."
"Seconds are lives," Kai said.
Kanae looked at Kagaya. "This would not replace swords."
"No," Kai agreed. "Only supplement them—until a slayer survives long enough to wield one properly."
Silence.
Then—
Kagaya laughed.
Soft. Warm. Certain.
"You are all proposing the same thing," he said.
"Not power—but mercy."
He turned his face toward Kai.
"Fear has shaped us for centuries. Perhaps it is time hope begins doing the same."
Sanemi looked away, jaw tight. "…Tch."
Gyomei bowed deeply.
Giyu nodded.
Tengen grinned. "The Corps just got way more interesting."
"It will be tested carefully," Kagaya concluded.
"But yes. We will adapt."
Kai bowed.
Not as a Hashira.
But as a protector.

Elsewhere — Infinity Castle
Muzan Kibutsuji was seated when he heard it.
Not shouted.
Not challenged.
Simply spoken by a trembling Lower Moon reporting rumors.
"…T-the humans are calling him the—Sun Hashira."
The room warped.
For a fraction of a heartbeat—
Muzan's fingers twitched.
A sharp, involuntary tremor ran through his body.
The memory struck like lightning:
A man walking through fire.
A blade that burned without flame.
A gaze that knew no fear.
"No," Muzan said calmly.
The demon before him collapsed, choking.
"That breathing style was erased," Muzan continued, voice smooth again.
"Every text. Every trace. Every successor."
He stood.
The castle obeyed his movement, walls bending.
"A title does not resurrect the sun," he said.
"Nor does a child wearing its name."
His lips curved—not quite a smile.
"…Still."
The shadows thickened.
"Inform the Lower Moons," Muzan said softly.
"Disgrace will not be tolerated."
The demon vanished.
Alone now—
Muzan clenched his fist.
Just once.
And then relaxed it.
"…Sun Hashira," he repeated.
Denial wrapped tightly around fear.
