Demon Slayer: Muzan, will you dance too?

"Is it Blood Demon Art: Black Blood Thorn?"

In the transparent state, it can be clearly seen that a large amount of demon blood in Muzan's body is converging towards his arms.

Veins suddenly bulged beneath his pale skin, and his once slender arms suddenly swelled up.

Seeing this, Kiyokawa Izumi already knew exactly what kind of Blood Demon Art this person was going to use.

Having revealed all his trump cards, he had no secrets left in front of Muzan.

Conversely, he also knew Muzan's background perfectly well.

A strong, suffocating stench of blood filled the air, and countless dark red thorns appeared out of nowhere, spreading from the arm.

Each thorn was as thin as a hair, yet incredibly tough.

Careful observation reveals that tiny barbs cover every thorn, dancing in the air like living venomous snakes, weaving an impenetrable web of death.

The tip gleamed with a chilling light, falling suddenly like a torrential downpour.

"There was a certain oppressive aura of a demon king about him... I was quite surprised that I was able to land a hit at first."

Such thinking is merely finding joy in suffering.

Muzan's fighting skills are not necessarily better than those of the Upper Moons.

This creature has survived for so long, seemingly having killed and fought countless battles, but has it truly experienced any evenly matched combat?

Most of them are probably just stomping noobs.

The only time was when I was so frightened by that person that I fled in a sorry state.

It's undeniable that it's strong.

Kiyokawa Izumi clearly didn't believe it when asked how much combat experience it had.

Of course, this character's Blood Demon Art may not be as flashy as Doma's, but its numerical strength is obvious.

"Type 5 - Dust-Free!"

The trajectory of the thorns' attack was clearly visible before our eyes.

With a sudden burst of force from his right hand gripping the hilt of the knife, he delivered dozens, even nearly a hundred, overlapping slashes, shattering all the thorns almost simultaneously.

Tiny droplets of blood, invisible to the naked eye, permeated the surroundings, and a nauseating stench of blood filled the air.

That's all; it's not something that can be easily taken down.

The boss, Muzan, who remains unchanged, seems not to understand the principle that even a lion uses its full strength to hunt a rabbit.

"Third Form: Silent Nine-Strike Combo!"

Without pausing or taking a breath, Kiyokawa Izumi sprang up like an arrow, his fighting style appearing extremely fierce and aggressive.

For this person, expending resources is useless.

If one insists on playing conservatively and focusing solely on defense, then there is truly no chance of victory.

Fortunately, I had already mastered the Crimson Blade; otherwise, the injuries would have healed instantly.

Is it feasible to suddenly close in on a wound that has never disappeared and unleash hundreds or thousands of cuts in an instant?

Just then, a long, indistinct whip lashed out swiftly and powerfully, its speed surprising even him.

"A mutated arm? So flexible, this is certainly troublesome."

Kiyokawa Izumi, who was in mid-air, almost instinctively made a defensive move.

The sudden force of gravity slammed into the blade, causing his arms to tremble slightly and interrupting his high-speed advance.

Slightly disheveled, Kiyokawa Izumi landed on the ground and took two or three steps back before barely managing to steady himself.

He glanced at the Nichirin Blade out of the corner of his eye—this was really bad. His body still had the strength to withstand the intense battle, but the Nichirin Blade was showing signs of severe wear and tear.

Damn Muzan, damn Doma, how come their bodies are so hard?

Large and small nicks are scattered all over the blade, especially from the hasty defense just now, where tiny cracks have already appeared.

In such places, the importance of weapons is self-evident.

As a swordsman, if you don't even have a usable sword, what difference is there between you and someone who has already been defeated and killed?

Fortunately, he has always been cautious.

He always carries multiple Nichirin swords with him when he goes out.

The only thing to be careful about now is to avoid breaking all the Nichirin swords.

"call--"

"If I remember correctly, this guy's blood contains a deadly poison."

It mixes its own blood into its attacks, and even a slight graze can damage the original cellular structure.

I quickly reviewed the relevant information in my mind.

Looking up, Muzan's figure was no longer visible on the pavilion.

"kindness?"

The sudden heavy blow to his arm startled him slightly, as if he was surprised that this person was so fast.

Unlike the spikes that extend from the arm, this weapon only uses the arm to strike the opponent. Although its power is exceptionally rapid, its threat level is actually far less than the former.

Kiyokawa Izumi, who easily saw through this move, had no intention of taking it head-on. While swinging her Nichirin Blade to block, she did not forget to deflect the force.

Although the body could not be stopped from moving backward, it was not injured as a result.

The only somewhat unexpected thing was this person's speed.

Judging from the current situation, it seems that the two sides are evenly matched, but in reality, the slightly serious boss Muzan has not used his full strength.

Kiyokawa Izumi was well aware of how many trump cards it still held—this creature wasn't just capable of transforming its arms, and it didn't only have one form.

There's not much to say; the sheer numerical strength is enough to crush him.

Faced with a ceiling-level existence, neither exquisite swordsmanship nor reckless burning passion can bridge the enormous gap that truly exists.
