Demon Slayer: Starting with the Great Swordmaster System, My Master Is Tsugikuni

The Dog-headed Demon exerted a little force and bit the other man's head to pieces.

Warm blood splattered everywhere, making the corners of his split mouth look even more terrifying.

As if he had donned a layer of red armor, the fur on the Dog-headed Demon's body stood on end, gleaming with a steel-like sheen beneath the moonlight.

His thick, massive tongue stretched out and licked the blood from his face.

It seemed as though he was savoring the previous taste, or perhaps considering his next target.

Feeling the Dog-headed Demon's gaze sweep over them, the swordsmen could not help but tremble.

Before the threat of death, few people could keep their eyes open and face it directly.

Only a female swordsman with braided pigtails and a cherry blossom hairpin in her hair refused to give up, launching an attack on the Dog-headed Demon.

Drawing her blade, she instantly thrust it toward the Dog-headed Demon.

The Dog-headed Demon remained unmoved in the face of the female swordsman's attack.

The sharp blade pierced through the defense of the Dog-headed Demon's fur, then pierced his shoulder.

But it had only pierced his shoulder.

Glancing at his shoulder, the Dog-headed Demon grinned hideously as though he felt no pain at all.

His right hand swung out, its sharp claws carrying a foul stench as they smashed toward the braided female swordsman.

As the claws in her vision drew closer and closer, the swordswoman knew her life was nearly over and instinctively closed her eyes.

Just then, the air suddenly grew hot.

Immediately afterward, a Flame Slash cut across the Dog-headed Demon's right arm.

With a squelch, a furry arm flew through the air.

Reeling from the pain, the Dog-headed Demon turned around with madness in his eyes.

There, a young man holding a crimson Nichirin Blade was slowly walking toward them.

The Final Third, the Surrounded Demon Slayer Corps

Under the intense pain, even the crazed Dog-headed Demon regained a trace of clarity.

Though he knew he had never seen this person before, for some reason, his heart was telling him to run!

Before becoming a demon, he had been a savage who drank blood and ate raw flesh.

After becoming a demon, his actions had become even more brutal and vicious.

Other than that lord and the six-eyed Demon Swordsman, he had never regarded any life as worthy of notice.

But tonight, right now, every cell in his body was warning him: run, or die!

Letting out a howl that sounded half wolf and half dog, the Dog-headed Demon turned and ran into the distance without the slightest hesitation.

No one could have guessed that he had been such a vicious demon just moments ago.

But before he could take more than two steps, the Dog-headed Demon felt a heat around his neck.

It was as if a scorching blade had sliced through his neck, burning his blood and consciousness to ashes.

Then, darkness fell over his eyes, and he never reacted again.

Scribe showed no reaction as he watched the Dog-headed Demon in the distance gradually turn to dust.

That instinct-like ability of his was indeed impressive, but before the absolute gap in strength between them, he had no chance to resist.

Seeing the Dog-headed Demon killed in a single strike, the other demons all turned around, their eyes filled with fear and apprehension.

Even the strongest demon had been so easily eliminated by this young man. They stood even less of a chance.

Bararing their teeth and roaring, the demons used every gesture they could to intimidate him.

But the young man merely took a small step forward, and those bluffing creatures instantly lost their nerve.

Turning around, all the demons fled in different directions.

Demons were cold-blooded and cruel by nature, with no intention of covering for one another or sacrificing themselves.

Moreover, Muzan had not ordered them to defend this place to the death. Faced with the threat of death, these demons naturally chose to flee.

Splitting up and running—rather clever.

A cold voice rang out as Scribe used Sun Breathing.

Eleventh Form: Halo Dragon Dance

For a moment, all the flames in the town seemed to be drawn here, surging toward this place.

The Demon Slayer Corps Swordsmen only felt the heat around them intensify, as though they were inside the furnace of hell, unbearably uncomfortable.

Though they could not see clearly, a Fire Dragon formed from blazing flames, with scorching fire coiling around its body, appeared in their eyes.

Wherever the Fire Dragon went, every demon was swallowed whole.

After a brief struggle, they all turned to ashes.

By the time the swordsmen came to their senses, every demon had already vanished between heaven and earth.

From hell to heaven in an instant—the immense contrast made the swordsmen's arms tremble as they gripped their blades.

One after another, they collapsed to their knees as though all strength had left them.

Without saying anything more, Mister Scribe turned to leave.

Though he had saved them, that did not mean he intended to approach them of his own accord.

Before he had taken more than a few steps, a woman's voice suddenly called out.

"Sun Breathing—that had to be the legendary Sun Breathing just now."

"Within the Demon Slayer Corps, the only ones who could use Sun Breathing were Mister Yoriichi from sixty years ago and his disciple, Mister Scribe."

"Could it be... are you Mister Scribe?!"

Hearing someone speak his name, Mister Scribe turned his head slightly and saw the female swordsman with braided hair.

He had never met her before, yet he sensed a somewhat familiar aura from her.

It resembled Water Breathing, yet it had evolved beyond Water Breathing.

More than sixty years ago, he had sensed this aura from a female swordsman.

"Are you a user of Flower Breathing? Do you know Inoue Mie?"

The braided female swordsman nodded emphatically, her face brimming with delight.

Since he knew Inoue Mie, the first-generation Flower Breathing swordsman, he naturally had to be the legendary Mister Scribe.

After all, according to the Demon Slayer Corps' records, Tsugikuni Yoriichi had always been known for being aloof and taciturn, speaking only with the Five Hashira and the Corps Master.

"This junior is Mami, a user of Flower Breathing. Inoue Mie is the ancestor of our lineage."

Mister Scribe nodded, but no particular delight appeared on his face.

He had only interacted with Inoue Mie a few times, after all. They were likely not as familiar as these people imagined.

"Set those matters aside for now. Tell me what the current situation is."

"Yes, Senior Mister Scribe."

Without even wondering why Mister Scribe still looked so young after sixty years, Mami told him everything she knew.

This was a small town on the outermost edge of the Demon Slayer Corps' territory, and its strength was relatively weak.

The farther inward one went, the more swordsmen were stationed there, and the stronger they were.

Several Hashira stood guard within the central Demon Slayer Corps' territory.

This morning, they had received news that another town had been brutally massacred.

Before they could send the news out, they had been suddenly attacked by demons.

Most of the townspeople had been killed and devoured, while a small number had been turned into demons and subsequently vanished without a trace.

They had intended to report to Headquarters after exterminating the demons, but the gap in strength had been far too great.

If Mister Scribe had not arrived, their fate would likely have been no better than that of the townspeople who had been eaten.

After listening to Mami, Mister Scribe could not help but ponder the matter.

According to her, the previously massacred town lay to the north, while this place was in the south.

If Muzan truly intended to lead an army to destroy the Demon Slayer Corps, there would have been no need to split his forces.

The confusion in Mister Scribe's eyes gradually faded as he understood their purpose.

Muzan and Kokushibo had split into two groups, intending to encircle the Demon Slayer Corps and wipe them out in one stroke!

The moment Mister Scribe figured it out, the system's voice sounded in his mind.

Mission: Head to the Demon Slayer Corps Headquarters and help them escape the crisis of total annihilation.

Reward: Clear World (1/3).

He had not expected to receive a mission prompt at such a moment.

And this time, not only had the reward been stated in advance, it was even the Clear World he had been waiting so long for.

Thinking of how Yoriichi had once asked him to help the Demon Slayer Corps, Mister Scribe could not help but wonder whether Yoriichi had already foreseen this day.

A faint smile appeared on Mister Scribe's face as he shook his head slightly.

It seemed that he and the Demon Slayer Corps would remain entangled for the rest of their lives.

While Mister Scribe was saving Mami and the others, the two armies of demons had already quietly joined forces.

At the foot of a great mountain, Kokushibo and Muzan met once more.

Muzan gave a cold smile and asked, "Rat-Earth, is the Demon Slayer Corps' main base up there?"

"Yes, my lord. I have already dealt with all the swordsmen responsible for guarding the surrounding area."

As he spoke, Rat-Earth licked the blood from his claws.

After hearing Rat-Earth's words, Muzan's cruel grin widened even further.

He walked before the demons, exuding the aura unique to the Progenitor of Demons.

Under the suppression of that aura, all beings, regardless of what they were, fell to their knees.

"You have only one task tonight."

Extending a pallid finger, Muzan pointed toward a nearby mountaintop.

"Kill!"

After hearing Muzan's command, a crimson gleam flashed through every demon's eyes.

They rose to their feet and let out all manner of howls.

Kokushibo drew the Demon Blade at his waist and aimed its tip at the mountaintop.

"Attack!"

With that, he took the lead and charged toward the mountain where the Demon Slayer Corps was stationed.

Caught off guard by the demons' sudden assault for the first time, and with the sentries already dealt with by Rat-Earth and the other demons, the Demon Slayer Corps' defenses were instantly shattered.

The swordsmen guarding the entrance barely managed to sound the alarm before they were dismembered and devoured by the vicious demons.

The sleeping swordsmen flew awake the instant they heard the warning, gripping their Nichirin Blades in hand.

Even so, the sudden attack still caught them completely unprepared.
