What Ryuya said was the truth.
Kyougai's writing was painfully unreadable. Anyone forced to sit through it would lose their sanity within minutes.
Kyougai's heart plummeted into despair. He fell silent at once.
The remaining Lower Moons grew even quieter.
Thank goodness they hadn't shown off any "talents." Kyougai had just demonstrated what happened when you tried to be clever.
"My name is Rui, Young Master Ryuya. Please guide me. I will obey your commands."
Rui stepped forward calmly.
Ryuya felt Muzan's gaze sharpen slightly.
Clearly, Muzan still cared deeply about this so-called adopted son.
"Very good. I'll remember you."
A neutral response.
Then—
The final one.
Enmu.
"Young Master Ryuya…"
Enmu's eyes were filled with feverish admiration.
"Seeing you makes my blood tremble with excitement. With you guiding us, the Lower Moons will surely flourish. Your charm is irresistible—"
"What do you mean by that?"
Ryuya cut him off smoothly.
"Are you implying my father's management was lacking?"
Silence.
Even Muzan's expression shifted.
He hated being criticized.
The Lower Moons felt a chill.
Death trap question.
But Enmu?
He only smiled wider.
"You misunderstand, Young Master. You are Lord Muzan's blood. Your excellence is proof of his greatness. That he entrusts us to you only demonstrates his unparalleled foresight."
Smooth.
Very smooth.
Muzan's lips curved faintly.
Satisfied.
Ryuya, however, was indifferent.
Enmu was the number one sycophant among demons.
Too enthusiastic.
Almost nauseating.
Still—
His adaptability was impressive.
Conclusion: a yandere-tier flatterer.
Ryuya nodded lightly.
"Accepted."
"From now on, Ryuya will manage the Lower Moons."
Muzan Kibutsuji announced.
"Yes, Father."
"Meeting adjourned."
Ryuya turned.
"Nakime. Send them out."
Nakime plucked a string.
The Lower Moons vanished.
Muzan watched.
Ryuya reprimanding demons.
Commanding authority.
Ordering Nakime.
A strange unease flickered within him.
But he had chosen this arrangement himself.
He said nothing.
"Father," Ryuya continued calmly, "I have something to discuss."
"Oh?"
"I wish to become an Upper Rank."
Muzan's eyes lit up instantly.
Excellent.
Ambition.
Desire for rank.
Hierarchy.
This proved loyalty.
This proved submission.
There was no rebellion here.
Wonderful.
"Nakime," Muzan ordered immediately, "summon the Upper Ranks."
Yes.
A Blood Battle for replacement.
Somewhere behind them—
Gyokko froze.
Was Ryuya eyeing his seat?
This wasn't a joke.
A Blood Battle meant death.
One Upper Rank would fall.
And become Ryuya's stepping stone.
Forest — Somewhere Else
Sunlight filtered through dense trees.
Shinobu Kocho moved lightly through the forest, her haori fluttering like butterfly wings.
Where exactly had Ryuya gone?
Finding someone was far harder than she expected.
"Pig Assault! Pig Assault!!"
Suddenly—
Loud, wild boar-like grunts echoed through the forest.
Shinobu paused.
What… was that?
She turned.
A human figure burst through the trees.
Bare chest.
Deerskin waist wrap.
Wild boar head mask.
Two Nichirin blades—
One heavily chipped.
It was undeniably a human.
But looked like something raised by wolves.
"Wahaha! I, Lord Inosuke, am so lucky! Two Nichirin blades! Die, Upper Rank One!!"
Inosuke Hashibira charged like an actual boar.
Shinobu's smile stiffened.
She began moving away immediately.
"Don't run! Hand over your Nichirin blade! I can tell you're from the Demon Slayer Corps!"
He pointed dramatically.
"That blade belongs to Lord Inosuke!"
He knows?
Wait—
That chipped sword in his hand…
That was indeed a Nichirin blade.
Though it looked like it had survived a war against a mountain.
Shinobu winced inwardly.
Her own blade was delicate.
Precise.
She would never allow this… wild boar… to touch it.
"Stop running, butterfly!"
Inosuke lowered his head and accelerated.
Is this child's brain functioning properly?
"Beast Breathing, Second Fang: Slice!"
He swung.
A silver arc tore through the air.
Shinobu leapt lightly onto a tree branch.
The massive trunk behind her split cleanly in two.
She blinked.
That power—
She vaulted to another tree.
"Annoying butterfly!"
"Beast Breathing, Fifth Fang: Crazy Cutting!"
Inosuke unleashed a frenzy of slashes.
Trees shattered around them.
Branches snapped violently.
Shinobu's eyes widened.
Breathing Technique.
No mistake.
He was using one.
And not poorly.
For a reckless pig—
He advanced by leaps and bounds.
