This Wild Boar Boy actually knew how to use a Breathing Technique from the Demon Slayer Corps?
And Beast Breathing at that—something she had never even heard of.
Shinobu Kocho kept thinking as she dodged his relentless, boar-like charges.
He had a Nichirin Blade.
He used a Breathing Technique.
But he was definitely not part of the Demon Slayer Corps.
If someone this… outrageous existed within the Corps, she would have known.
Which meant—
This Wild Boar Boy was a natural prodigy.
"Moshi moshi~ could you please stop chasing me?" Shinobu called lightly.
"Nichirin blade! Hand it over!"
His obsession was deep.
Shinobu's smile stiffened slightly.
"Um… did you teach yourself your Breathing Technique?"
"Breathing Technique?"
He paused.
"Yes. The Beast Breathing you just used."
Inosuke puffed up proudly.
"It's amazing, right? Hahaha! I knew Lord Inosuke is the strongest! I'm the King of the Mountain! Pig Assault!!"
…Communication was impossible.
Shinobu gave up.
His thought process clearly operated on a different frequency.
Still—
Seeing him strengthened her resolve.
If he could develop Beast Breathing on his own…
Then she could absolutely develop her own unique style.
As for asking him for guidance?
Absolutely not.
That annoying Ryuya, at least, could speak normally.
Decision made, she accelerated.
"Running away again?! How troublesome! Beast Breathing, Seventh Fang: Spatial Awareness!"
Inosuke stilled.
The world around him shifted into grayscale.
The wind.
The insects.
The tremor of footsteps.
Everything became sharply defined.
"Don't even think about escaping! Pig Assault!!"
His pursuit became terrifyingly precise.
No matter how Shinobu shifted direction or used cover, he tracked her perfectly.
She clicked her tongue inwardly.
Escape was impossible.
She drew her blade.
"Water Breathing, First Form: Water Surface Slash!"
A flowing arc of water cut toward him.
Clang!
The moment their blades collided, she felt the difference.
Her wrist trembled.
He was physically stronger.
A direct clash was disadvantageous.
So she retreated while fighting.
Inosuke advanced recklessly, eyes locked onto her Nichirin Blade.
"This won't do…"
Shinobu's hand brushed the pouch at her waist.
Sleeping pollen.
It required time to take effect—
But it was her best option.
She scattered a faint purple powder into the air.
Then—
Deliberately—
She threw her Nichirin Blade to the ground.
Just as expected—
Inosuke stopped chasing her.
He grabbed the blade and burst into wild laughter, waving it around triumphantly.
Shinobu smiled faintly.
Keep breathing. Soon your limbs will feel heavy…
He examined the blade—
Then began smashing it enthusiastically against the ground.
Chipping it.
Dent by dent.
Shinobu's eyebrow twitched.
A dangerous thought of dismemberment briefly crossed her mind.
This child absolutely had issues.
"…Why am I sleepy…"
Moments later, Inosuke's legs buckled.
He collapsed.
"Finally."
Shinobu approached cautiously and poked him.
No response.
She retrieved her blade, heart aching at its abused condition.
The nicks felt like wounds on her own body.
"Let big sister see what you look like."
She gently removed the boar mask.
Underneath—
Short dark-blue hair.
Delicate features.
Almost beautiful.
She blinked.
The contrast was absurd.
Voice and face did not match at all.
What kind of childhood trauma made someone believe they were a pig?
She replaced the mask and left him there.
The pollen wouldn't last long.
He'd wake up unharmed.
After exiting the forest, Shinobu entered a small town.
She was tired.
Hungry.
And still had no clue where Ryuya was.
As she searched for food, a commotion caught her attention.
A bespectacled young man was berating a woman in the street.
The woman wore a cherry-blossom-colored kimono.
Long pink hair with green tips.
Braided.
Soft eyes.
Two small beauty marks beneath them.
She looked almost dreamlike.
Her face was flushed as she stared at her toes, clearly mortified.
"A girl with the strength of a bull! No delicacy at all! Only livestock would marry you!"
The man scoffed.
"And that ridiculous hair color! If our children inherited it, how frightening would that be?"
"I-I'm sorry…"
Mitsuri Kanroji lowered her head.
Her voice was soft.
Barely audible.
"And your appetite! You eat like a monster! It's embarrassing!"
Passersby stared.
Whispered.
Mitsuri's fingers twisted nervously in her sleeves.
Was her hair truly strange?
It had changed color because she ate too many sakura mochi as a child.
Was that her fault?
Was eating a little more such a crime?
She paid for her food.
Why was she being treated like this?
Her first blind date—
She had imagined kindness.
Acceptance.
A warm future.
Instead—
Public humiliation.
Her throat tightened.
She just wanted to disappear.
"Honestly, I was excited about today," the man sneered. "What a waste of my time."
He continued venting.
Mitsuri's foot shifted backward.
She was about to flee—
"Wait."
A soft yet clear voice cut through the air.
Shinobu stepped forward, smile sweet—
Eyes cold.
