# Chapter 329: What are the Six Powers? What is Haki?

"Hey, Sister Mitsuri, where did Nezuko and Tanjiro go? I haven't seen them for the past two days."

Mumei raised her head, shifting her amber gaze from the duel of Gale and Flame to Love Hashira Mitsuri Kanroji beside her.

Ever since she heard Sakonji Urokodaki recount the story of the siblings that day, she had felt a sense of empathy.

Nezuko had turned into a Demon, but she had Tanjiro by her side, and he was doing his utmost to find a way to turn her back into a Human. Just like how Ikoma had once told her he would definitely find a way to turn her back into a Human.

Such similar experiences made it hard for Mumei not to care about Nezuko.

Especially since they were close in age; she was thirteen this year, and Nezuko was fourteen.

Hearing the question, the latter widened her large, leaf-green eyes, leaned down, and showed a very warm and cheerful Smile.

"They were sent to Sister Shinobu's Butterfly Mansion for treatment!"

She also had a good impression of this super cute little girl and then asked with anticipation, "Mumei, you don't know a Breathing Style yet, right? Do you want to be my Tsuguko? I can teach you Love Breathing!"

A Tsuguko is a Demon Slayer Corps member personally trained by a Hashira. They usually choose Children with considerable Talent, who are highly likely to become Hashira themselves in the Future.

"But I can't use that kind of soft Blade like a Whip. If I had to choose a Breathing Style, I think I'd prefer to learn Sister Shinobu's Insect Breathing."

Mumei refused her somewhat sheepishly.

"How could this be..."

Love Hashira Mitsuri Kanroji looked quite disappointed, muttering, "Sister Shinobu's Sword Techniques rely heavily on various poisons."

"But I feel that Insect Breathing's inherent Agility and High-Speed Movement thrusts are enough even without poison. It's very suitable for someone like me who also lacks Strength..."

Mumei voiced her observations, while thinking to herself, "Besides, my Future opponents won't necessarily all be Monsters like Demons with super strong healing Abilities."

Love Hashira Mitsuri Kanroji chuckled, "But Sister Shinobu already has a Tsuguko~"

"Does that mean I can't learn Insect Breathing if I'm not a Tsuguko?"

Mumei asked with a troubled Expression on her pretty face.

"Of course you can!"

Just then, Shinobu Kocho approached from who knows where, a Smile on her face giving off a very calm and gentle Feeling.

"Kanao is learning Flower Breathing. It just so happens that my Insect Breathing doesn't have a successor yet. How about coming to my place tonight to take a look?"

"Yes!"

Mumei's eyes lit up with surprise and gratitude. "I love your 'Dance of the Butterfly: Caprice' the most! Your Posture is truly as light as a butterfly. Thank you, Sister Shinobu!"

"It seems Mumei really likes butterflies. That's wonderful."

"I have many butterflies there, you know. And since you are Mr. Mitsui's daughter, with your Talent, perhaps you might even create a unique 'Butterfly Breathing' in the Future~"

Shinobu Kocho took Mumei's fair and tender little hand and chuckled, which made Mitsuri Kanroji pout her pink lips and say unhappily, "Actually, soft Blades aren't that hard to learn either..."

"Alright, you come too tonight. It feels like it's been a long time since we soaked in the Hot Spring together."

Shinobu Kocho was like a perfect older sister, soothing her slight grievance and disappointment with gentle words.

[Thud!]

Just as the three women were chatting to the side, a sudden Clanging Sound and the sound of bursting Flame erupted from the other side.

Lucci's Katana, wrapped in flowing Flame, turned into a red flash and stopped just before Flame Hashira Kyojuro Rengoku's throat.

"First Form: Shiranui."

The former uttered the words Un hurried, bringing a burning end to this Sparring match, then quickly withdrew his Blade and sheathed it.

"Thank you for the guidance!"

Kyojuro Rengoku didn't seem discouraged by losing at all. Instead, he laughed heartily with full Aura, "As expected of Mr. Mitsui, amazing!"

"You can strengthen your Training in terms of Strength. Since Flame Breathing follows a Blade path that overwhelms with Aura, you must ensure you have enough suppressive Power."

Lucci gave his Suggestion in a calm tone.

"Thank you very much!"

Kyojuro Rengoku bowed again, then withdrew his Nichirin Blade and returned to Stone Hashira Gyomei Himejima, saying with a Smile, "It's your turn."

"Namu Amida Butsu..."

The latter clasped his hands together and chanted a Buddhist phrase, then swung the Prayer Beads in his hand and stepped forward. He stopped after reaching Lucci's opposite side.

"Finally, it's him."

Lucci looked at the monk-like giant before him, who was even taller than himself, with interest.

He had neat, short black hair, a distinct long scar on his forehead, wore the Demon Slayer Corps Black Uniform underneath, and a brown Haori with the words 'Namu Amida Butsu' written on it over it. He wore a string of large and Trumpet-sized crimson Prayer Beads around his Neck and on his hands.

"Where is your Weapon?"

"Here."

Stone Hashira Gyomei Himejima reached behind him under his Haori and pulled out a Meteor Hammer and a broadaxe connected by a thick, long Iron Chain.

"Is that your Nichirin Blade?"

Lucci raised an eyebrow in surprise. The previous Hashira all had Katanas, but this guy was so unique.

"Yes, it contains a very high concentration of Scarlet Crimson Sand Iron, thus making it more lethal to Demons. The only problem is that it's quite heavy, Namu Amida Butsu..."

Gyomei Himejima explained simply, but his words left the Hashira watching from afar speechless.

"It's not 'quite heavy', it's ridiculously heavy! Although I can lift it, I can't use it for Combat at all. What a flamboyant Weapon..."

Sound Hashira Tengen Uzui couldn't help but complain.

"Is that so? If that's the case, there's no need to imitate your 'Stone Breathing'."

Lucci considered for a few breaths, then, under everyone's shocked Gazes, he threw the Katana at his Waist to Mumei and stood empty-handed. "I've been fighting using your methods until now. Next, it's time to show my Combat style."

""????""

A bunch of Big Question Marks appeared above the heads of those Hashira.

"Could he be planning to fight Brother Himejima bare-handed?" Mitsuri Kanroji could hardly believe the words she was saying.

"It seems so..."

Obanai Iguro said with a frown, "Has defeating eight of us made Mr. Mitsui so arrogant?"

"No, Father's bare-handed Strength is even stronger than when he uses a Blade~" After speaking, Mumei blinked playfully.

However, no one believed her words, only taking it as a Child's blind adoration for her Father.

As for Gyomei Himejima, the person involved, he first exchanged glances with Lucci. After confirming that the other party wasn't joking, he didn't say anything more.

"Then allow me to witness your superb Moves, Namu Amida Butsu..."

As soon as his voice fell, he immediately made the first move. Since Hayato Mitsui had given up the first attack in the previous few Combat, there was no need to be overly polite.

The Stone Hashira's arm instantly solidified as he exerted force, his Muscles bulging in knotted cords.

The next moment, the Iron Chain in his palm shook and vibrated, and the Meteor Hammer and broadaxe were swung out with a Roar, tearing through the Air along the way and emitting two explosive sounds.

"First Form: Serpentinite Bipolar!"

However, his 'Stone Breathing' didn't seem to have the flamboyant elemental Special Effects like other Breathing Styles, only a faint layer of gray Energy/Force attached to the Weapon.

But its momentum was no weaker than the latter. The Whistling Sound that caused the Air to Tremor fully displayed the powerful Sense of Power of this Move.

Yet, facing such a fierce attack, Lucci merely raised his Right Hand, and as he clenched his fist, a layer of black with a Metallic sheen appeared out of thin Air on his skin.

[Dong!!]

The next moment, the pitch-black fist first smashed open the Meteor Hammer, creating a sound like a striking bell, then the fist turned into a palm and slapped away the broadaxe on the other side.

This scene stunned everyone except Mumei.

But Lucci paid no mind to the Feelings of these Hashira. He stomped on the Ground beneath him, leaving trails of Afterimages as he charged forward rapidly.

"Fourth Form: Rhyolite Rapid Conquest!"

Although Gyomei Himejima was blind, he could clearly Understand Lucci's movements through the Tremor within a certain range.

Although he felt equally incredible in his Heart, his response was not slow. He forcefully rotated the Iron Chains with both hands, controlling the flying Meteor Hammer and broadaxe to spin, attacking Lucci's back at an extremely high Speed.

"Finger Pistol!"

Lucci had already closed in on the Opponent. Ignoring the Whistling Sound behind him, his bent Right Hand index finger shot out like a Bullet.

[Clang!]

However, this super High-Speed Movement Finger Pistol at such close range was precisely blocked by the straightened Iron Chain between the Stone Hashira's hands, and the Iron Chain was very tough, showing no signs of breaking.

But Lucci's Finger Pistol did not end there. It spread out like buckshot in front of him, covering the Opponent from top to bottom.

In an instant, fingers and Iron Chains engaged in dense and fierce offense and Defense, and rapid clanging sounds erupted In the Court.

"Such keen Perception."

Seeing that the Opponent could protect his entire Body impenetrably with just a slightly thicker Iron Chain, Lucci realized that the Stone Hashira's Spirit Perception had completely reached the level of Observation Haki.

"Shave!"

Suddenly, Lucci turned into an Afterimage and disappeared from his original spot, dodging the Meteor Hammer and axe blade that were about to hit his back, and instantly reappeared behind Gyomei Himejima.

"What?"

The latter had not expected Lucci's Speed to become so fast. He felt that this had exceeded the Limit that a Human Body could achieve, comparable to the Blood Demon Art of those Demons, which is a Superpower.

[Bang!]

With a muffled sound, Gyomei Himejima's back was hit by a heavy kick, and he flew forward with a groan of pain. But during this process, he heard the 'Hayato Mitsui' say another strange term.

"Tempest Kick!"

The next moment, the Stone Hashira's Expression changed drastically. Ignoring the pain in his back, he twisted his Body with all his might, quickly pulled the Iron Chains in his hands, and continuously swung the Meteor Hammer and axe blade around himself as the center, barely forming the Move a second before the sharp tearing sound approached.

"Third Form: Stone Body Skin!"

More than a dozen gray scratches formed a Net, blocking a bright blue Crescent Moon-shaped Energy/Force Blade. Although it was blocked, the powerful Energy/Force contained within the latter knocked the Stone Hashira flying again.

"Oh my god, what... what is that?"

Mitsuri Kanroji subconsciously covered her mouth with her hands, already too shocked to Control herself.

It wasn't just her. Flame Hashira Kyojuro Rengoku, Sound Hashira Tengen Uzui, and everyone else, without exception, had Expressions of utter astonishment.

He could block Brother Himejima's Meteor Hammer and axe blade bare-handed, instantly flash behind someone, and now even kick out Hotei that tear through the Air with just his legs?

Is this really something a Human can do?

"That's the 'Six Powers', a Martial Arts that surpasses the Human Limit of Physical Ability!"

Mumei stepped forward at this moment, with her hands behind her back, standing on her tiptoes, and with a beautiful Smile, she began to introduce them to these Hashira.

The moment Lucci used the Six Powers, she knew he was going to reveal his hand to the Demon Slayer Corps, and she also had a hidden Earphone in her right ear.

"The Move Father used earlier, the continuous jabs with his finger, is 'Finger Pistol' from the 'Six Powers'. It gives the finger the Speed and Power of a Bullet, easily piercing Steel!"

"The Move that instantly appeared behind the Stone Hashira is 'Shave'. It involves stepping on the Ground dozens of times at High-Speed Movement in an instant, using the resulting explosive reaction force for super High-Speed Movement!"

"Then the Hotei he kicked out is 'Tempest Kick', a Martial Arts that creates a vacuum slash through super High-Speed Movement and powerful kicks!"

The little girl gave an Explanation of each Technique one by one, counting on her fair and tender fingers, under everyone's Gaze, in a rather romantic manner.

"Besides these, there's also 'Iron Body', which makes the Body as hard as Steel; 'Paper Arts', which allows the Body to become as light and thin as Paper; and 'Moonwalk', which lets you walk freely in the Air by stepping on it!"

Perhaps it was a coincidence, but as Mumei spoke, Lucci demonstrated the actual Effects of 'Iron Body', 'Paper Arts', and 'Moonwalk' In the Court in the Combat.

He first took the swinging Meteor Hammer and axe blade head-on with his Body completely unharmed.

Then, he released all the Strength from his Body, using the changes in the Air Current generated by the axe blade and Meteor Hammer to easily dodge wave after wave of attacks at the last moment.

Finally, he leaped directly into the Air, truly stepping on the invisible Air, shifting his position amidst bursts of Air explosions, and finally knocked down Gyomei Himejima, the Demon Slayer Corps' strongest Stone Hashira, with a single punch!

Silence, dead silence. Apart from the occasional sound of Wind blowing across the Ground, the Ubuyashiki Estate seemed to fall into a moment of Space-Time stagnation.

"Then, can you do that too?"

Shinobu Kocho asked Mumei, suppressing the Gale and Giant Waves in her Heart.

"Hmm, I can't, because the prerequisite for cultivating the 'Six Powers' is to have Physical Ability that surpasses the Human Limit." Mumei scratched the back of her head awkwardly and gave a Bitter Smile.

"So, when Mr. Mitsui took the Meteor Hammer head-on bare-handed earlier, it was because he used 'Iron Body' from the 'Six Powers'?"

The person asking was Love Hashira Mitsuri Kanroji, because she felt that the Effect of 'Iron Body' was the same as when she tensed her Muscles.

"No, Father's hand turned black at that time, didn't it? That was Armament Haki~"

Mumei gave a sweet Smile and said, "It's an Ability that turns Will into Armor to enhance the Body's Defense and attack Power. Generally, we can't see Haki, but he used a Technique called 'Hardening'. This Technique condenses Haki to produce that pitch-black color."

"So, can you do that too?"

"Uh, no, because Armament Haki also requires a certain physique to support it. But I can use Observation Haki!" Mumei quickly said.

Just as she was about to give an Explanation of what Observation Haki was, Lucci walked over and looked at the 'Lord' Kagaya Ubuyashiki and all the Hashira present.

"Next, we need to talk inside, about Muzan Kibutsuji and the Twelve Kizuki being completely wiped out by us, and also about the Matters concerning the World Government..."
