Sanemi Shinazugawa's blood was rare blood—intoxicating and disruptive to demons.
Hearing the exchange, Gyomei Himejima immediately understood what Sanemi was doing.
"Tengen, assist Shinazugawa and rescue Genya! Only Ryuya stands in our way. Break through him, and we can save Shinazugawa Genya!"
"I'll support Rengoku-sensei!"
Kanae, clutching the broken remains of her Nichirin Blade, hurried toward Shinjuro Rengoku, who was still desperately battling the towering ice Bodhisattva.
Nearby, Jigoro Kuwajima had completely lost the ability to fight.
"Wind Breathing, Seventh Form: Gale—Tengu Wind!"
Sanemi Shinazugawa slashed wildly. Spiraling green wind blades howled toward Ryuya.
"Stone Breathing, Fifth Form: Wheel of Gyomei!"
Gyomei shattered the bluestone beneath his feet and launched himself skyward. His chain whipped violently, flail and axe striking in relentless succession.
The heavy weapons accelerated within the gale.
"Sound Breathing, Fifth Form: String Performance!"
Tengen Uzui spun his twin blades. Explosions detonated one after another around Ryuya.
Wind.
Stone.
Explosions.
Yet to Ryuya—
It all moved in slow motion.
Transparent World.
It wasn't that the three Hashira were slow.
It was that Ryuya's perception had stepped into an entirely higher realm.
Every heartbeat stretched.
Every movement was clear.
Tengen's eyes widened in horror.
Ryuya wasn't dodging randomly.
Every step he took perfectly avoided the next explosion—before it even happened.
Why?!
Sweat streamed down Tengen's face.
"Moon Breathing, Sixteenth Form: Moonbow—Solitary Moon!"
Ryuya drove his demon blade into the ground.
A massive dark-purple crescent descended from the sky like a falling meteor.
The gale was torn apart.
Gyomei's flail and axe were blasted aside.
The crescent struck all three Hashira at once.
Blood burst outward.
Cold.
A bone-deep cold invaded their bloodstreams, merging with Doma's ice poison.
Their bodies trembled violently.
"Wind Breathing, Sixth Form: Black Wind Mountain Mist!"
Sanemi forced his frozen limbs to move. A black wind blade slashed toward Ryuya's chest.
"Moon Breathing, Sixth Form: Eternal Night—Lonely Moon!"
Multiple crescent blades formed instantly before Ryuya.
Sanemi's attack shattered in front of him.
He staggered.
His vision blurred.
What was all his effort for?
Why was the gap still so vast?
His rare blood—
It had no effect.
If anything, Ryuya seemed to grow stronger with every exchange.
Has he already overcome it?
Sanemi's blood felt frozen solid.
His arms wouldn't lift.
Brother…
Bound to the pillar, Genya Shinazugawa struggled desperately.
He couldn't break free.
"Demon Slayer Corps… this is the end."
Ryuya's crescent blade swung toward Sanemi's throat.
At that instant—
Gyomei stepped forward.
His mountain-like body shielded Sanemi.
Veins bulged across his arms.
Gray-black rock patterns spread over his skin.
Before all demons are slain, the Demon Slayer Corps shall endure!
His voice thundered like a mountain collapsing.
The Demon Slayer Mark had awakened.
Ryuya's eyes narrowed slightly.
The Demon Slayer Mark.
A forbidden blessing.
Power gained at the cost of life.
Those who awakened it would not live past twenty-five.
Gyomei felt the ice poison weaken.
His movements became smoother.
Stronger.
"Stone Breathing, Second Form: Upper Smash!"
He kicked the chain, sending the flail hurtling toward Ryuya's skull with terrifying force.
Ryuya shifted slightly.
He avoided it effortlessly.
Even with the Mark awakened—
Gyomei was not yet a true threat.
Without Transparent World, the gap remained.
"Stone Breathing, First Form: Serpentine!"
Gyomei hurled both weapons again, buying time.
"Shinazugawa! Tengen! Rescue Genya! I'll hold him!"
Even with the Mark, he knew—
He could only stall.
Ryuya fought calmly.
Unhurried.
Unpressured.
Sanemi forced himself upright.
His entire body was soaked in blood.
He staggered toward Genya.
"Brother!"
Genya's voice cracked.
Sanemi was at his limit.
One more step could cost his life.
He didn't stop.
Tengen moved as well, forcing his heavy legs forward.
To save Genya—
Move!
"Yes!!"
Tengen roared, biting down on bloodied teeth as he charged toward Genya.
