Breathing Technique 2.0

Even the Martial Demon group could no longer stomach Doma's shameless remarks.

They prepared to strike.

Yet at that very moment, Doma unfolded his folding fan without warning and flicked it lightly toward the four demons before him.

"Whoosh..."

A biting, frigid wind swept through in an instant. The expressions and movements of the four Martial Demons froze solid, as if they had been transformed into lifelike ice sculptures.

"Lord Akaza, I've come to find you."

As the words faded, Doma's figure vanished from the street.

Three months later, the Demon Slayer Corps' Sun Hashira, Tanjuro, having recovered his health, officially went online!

Following the Kasugai Crow in the sky, Tanjuro began the first demon-slaying mission of his life.

Watching Tanjuro's slowly receding figure, with that axe-shaped Nichirin Sword hanging at his waist, Kujo Tachibana could not let it go.

Why on earth did he have to be so stubborn and insist on having an axe-shaped Nichirin Sword?

In Kujo Tachibana's eyes, Tanjuro was the second "heretic" currently existing within the Demon Slayer Corps!

Although Tanjuro was incredibly skilled with an axe, could one really perform the thirteen forms of Sun Breathing with an axe?

Kujo Tachibana expressed his doubts...

Come to think of it, that kid Tanjiro wouldn't learn from his old man in the future, would he?

To keep his information hidden, Kujo Tachibana had not stepped out of the Demon Slayer Corps headquarters since his return.

"Ubuyashiki Kagaya, has there been any progress in Lady Tamayo's research?"

Ubuyashiki Kagaya's lips curled slightly as he looked at Kujo Tachibana and teased:

"It should be slightly faster than the progress of you, the 'Sleep Hashira'!"

Hearing this bizarre title, Kujo Tachibana's face darkened, and he shouted angrily:

"Is that any way for a Master to act! I don't know who's in charge, but don't let me catch that rotten-hearted little brat!"

He didn't even know which bastard had started calling him that first!

Now, the members of the Demon Slayer Corps were calling him Lord Sleep Hashira behind his back!

Ever since their group returned to the Demon Slayer Corps headquarters three months ago.

In order to develop his own breathing style, Kujo Tachibana would faint from oxygen intoxication every few days.

It wasn't until this past month, as the rhythm and frequency of Kujo Tachibana's Body Breathing shifted significantly, that this "oxygen intoxication" began to improve.

However, this also indirectly helped Kujo Tachibana verify that his direction was not wrong.

As his Body Breathing method grew closer to his "exclusive breathing style," the massive amount of oxygen entering his body was naturally consumed more efficiently, which was why the frequency of Kujo Tachibana's fainting spells had gradually decreased.

Yet, those little brats in the Demon Slayer Corps headquarters had long since given him a nickname—Sleep Hashira!

Suppressing the anger in his heart, Kujo Tachibana snorted coldly and looked at Ubuyashiki Kagaya with a haughty air:

"I don't have the time to deal with them right now. Once I finish creating my new breathing style, just watch me beat their butts!"

Ubuyashiki Kagaya laughed heartily. He knew Kujo Tachibana didn't mean it; saying such things was just his way of joking around.

Still, Ubuyashiki Kagaya asked with some curiosity:

"Is that new breathing style you mentioned really as powerful as you brag?"

"All that talk about kicking Muzan and punching Kokuhibo—you aren't just blowing smoke, are you?"

Kujo Tachibana rolled his eyes at these words, his tone filled with disdain:

"What do you mean, which breathing style is powerful? It's me who is powerful!"

"You aren't a martial artist, so you wouldn't understand even if I told you. Ubuyashiki Kagaya, just wait and see!"

"Once my breathing style is perfected, those two will be nothing but small fry in my eyes. Are they even worthy of being my opponents?"

"When the time comes, just act according to the plan and lure them both out. I'm only worried that only one will show up and the other will hide in fear; if that happens, I'll truly be at a loss."

Especially that coward Muzan; after all, Muzan had a precedent for using escape techniques, and he didn't want to end up like Yoriichi, eventually being worn down to death by Muzan.

Besides, he, Kujo Tachibana, was a short-lived person... time was even more pressing.

Unfortunately, these words from Kujo Tachibana did not comfort Ubuyashiki Kagaya; instead, they made him feel even more that Kujo Tachibana was truly bragging...

Ubuyashiki Kagaya opened his mouth to speak but stopped, saying nothing, only thinking to himself:

Forget it, I won't dampen his enthusiasm. I'll wait until he actually creates that so-called invincible breathing style.

Little did Ubuyashiki Kagaya know that this day would come so soon!

Five days later, at night.

At this moment, Kujo Tachibana sat cross-legged beneath a large tree in the courtyard, his eyes closed.

His long white hair drifted without wind, moving in rhythm with the expansion and contraction of the pores all over his body.

As his body gradually adapted to the Body Breathing, and as Kujo Tachibana continued to alter the frequency and rhythm of his Body Breathing...

The duration for which he could maintain full-power external respiration without falling into a state of oxygen intoxication was growing longer and longer.

Kujo Tachibana knew that the perfect breathing technique truly belonging to him was on the verge of completion!

Perhaps, it would happen this very night...

Pfft... Kujo Tachibana, completely immersed in his internal focus, seemed to hear a soft pop, and the sense of euphoria radiating from every part of his body gradually began to overwhelm him.

In an instant!

As his pores opened and closed in unison, the air within a five-meter radius of Kujo Tachibana was suddenly sucked dry, as if swallowed by a whale!

For a brief moment, he had fallen into a state of vacuum.

The roar of thunder emanated continuously from within Kujo Tachibana's body, and electric currents, resembling slender snakes, scrambled to surge out through his pores.

Even the thunderclouds in the sky seemed to be drawn by the massive amount of active electrons on the ground, gradually gathering together. The next second...

"BOOM!!!"

"BOOM!!!"

"BOOM!!!"

A series of violent thunderclaps jolted Ubuyashiki Kagaya awake from his slumber.

Ubuyashiki Kagaya held his wife, Amane, who had also been startled by the thunder, and said softly:

"That thunder is truly deafening... is it going to rain?"

"Indeed. I have never heard thunder this loud before; it felt as if it were ringing right beside my ears," Ubuyashiki Amane replied, full of confusion.

After such a "fright," the two had no desire to sleep, and just then, a gentle knock on the door sounded quietly.

Ubuyashiki Kagaya frowned; he knew that unless it was something of great importance, no one would disturb him at such a late hour.

"What is it? Has something happened?" Ubuyashiki Kagaya asked toward the door.

"Master, the lightning just struck the tree in the courtyard of the Rumble Hashira's residence."

"When we rushed over to put out the fire, the Rumble Hashira asked us to deliver a message to you."

"What message did the Rumble Hashira ask you to deliver?" Ubuyashiki Kagaya asked curiously.

"The Rumble Hashira said that he is ready."

Upon hearing these words, Ubuyashiki Kagaya was slightly stunned, and his pupils dilated rapidly in an instant...

My dear young talents, give this breathing technique a wild, cool, and flashy name!
