The air trembled with the sound of battle's climax.
Sahiru turned to Tanjiro, his eyes blazing scarlet and violet.
"Tanjiro—now!"
With a fierce nod, Tanjiro gritted his teeth.
"Right behind you!"
The two blurs of fire and fury charged forward, their feet pounding through the cracked earth of the ruined battlefield.
Muzan, sensing the inevitable, panicked.
His body began to ripple and twist.
He shouted, "I'll divide—I'll vanish into them!"
But—nothing happened.
His body trembled.
His cells locked in place.
His eyes widened.
Then—a voice echoed like a whisper of vengeance.
Tamayo.
"Oh? Trying to run? Silly Muzan… Did you forget the drug I gave you? Splitting won't help you. Your end is certain."
Muzan roared in fury, tendrils bursting from his back like writhing serpents—twelve massive, thrashing whips, black and red like blood-stained steel.
But eleven lights met them head-on.
Genya stood tall, firing a final barrage—
"Soul-Forged Shot: Final Barrage - Hollow Demon's End."
Shinobu, graceful as a dancer, darted through—
"Insect Breathing, Final Form: Wisteria Death Waltz."
Obanai, with eyes burning—
"Serpent Breathing, Final Form: Coiling Serpent Execution Fang."
Mitsuri, her whip blade lashing like a storm of affection—
"Love Breathing, Final Form: Blooming Heart Spiral."
Sanemi, the wind screaming in fury—
"Wind Breathing, Final Form: Tempest Purge Slash."
Muichiro, mist solid as steel—
"Mist Breathing, Final Form: Phantom Twin Heavens."
Giyu, the calm before the flood—
"Water Breathing, Final Form: Tidal Eternity Strike."
Inosuke, laughing wildly—
"Beast Breathing, Final Fang Form: Frenzied Fangs of the Wild God."
Zenitsu, lightning incarnate—
"Thunder Breathing, Final Form: Heaven's Thunderstorm Flash."
Gyomei, his flail and axe shattering stone—
"Stone Breathing, Final Form: Earthquake of Divine Judgment."
Kanao, flower petals dancing around her—
"Flower Breathing, Final Form: Petal Bloom Requiem."
They shattered Muzan's tendrils, ripping through the darkness with the power of their loved ones, their pain, their hope.
Sahiru stood tall, cloak billowing, hair catching the wind.
He looked up at Muzan's crumbling form and said,
"Now you'll understand…the weight of a human life."
And then—
The sky began to change.
Dawn.
The sun broke the horizon, golden rays piercing the world.
Muzan screamed, his flesh sizzling, black smoke rising from his skin.
Tanjiro and Sahiru ran toward him, blades drawn, the power of their ancestors, friends, and bonds behind them.
"HINOKAMI KAGURA: FINAL FORM — SAN HALO DRAGON DANCE!"
"FACADE BREATHING: FINAL FORM — DRAGON OF SCARLET AND VIOLET ILLUSIONS!"
Two dragons—one golden flame, the other a swirling, majestic force of violet and crimson—spiraled around them, illuminating the sky.
With a final roar—
They slashed down—
Their blades crossing at Muzan's neck.
SLASH.
Muzan Kibutsuji's head flew.
His body burst into ash.
His roar turned into silence.
And the sun rose in full.
They had won.
All thirteen demon slayers collapsed, breathless, bloodied, and broken—but alive.
They looked at each other. Tears welled. Laughter choked through sobs.
Sahiru, blood staining his cloak, looked to the sky, breathing deep.
He whispered with a soft, tired smile—
"Suzune… we won."
And in the golden rays of dawn—peace finally returned to the world.
