Without a doubt, this is a person of great charisma.
When the successor of Sun Breathing appears in this era, Nezuko undergoes an unprecedented transformation, and when Demons and the Demon Slayer Corps work together...
Both Ubuyashiki and Tamayo were now utterly convinced.
Kibutsuji Muzan, your doomsday has arrived.
After a solemn speech, Ubuyashiki Kagaya directed the conversation toward what he currently cared about most: "Miss Mizuki."
"The intelligence you previously shared with us mentioned a crucial sentence."
"An Upper Rank requires the combined strength of at least three Hashira to fight against. I wholeheartedly agree with your assessment."
"The last record of the Demon Slayer Corps killing an Upper Rank occurred more than a hundred years ago."
"And in this era, Kochou Kanae, the Flower Hashira who fought Upper Rank Two four years ago, explicitly stated:"
"That demon was merely playing around."
Hearing about her older sister, Kochou Shinobu subconsciously held her breath.
Every time she thought about the situation back then, she felt a chill run through her body.
She almost lost her sister.
"Hmm, Upper Rank Two, Douma. I've dealt with him before. That demon..." Mizuki recalled for a moment, "Because he lacks human emotion, his behavior appears somewhat strange."
Honestly, from an objective point of view, it was difficult for her to hate Douma, because he was simply a psychopath.
When other arrogant demons were slain, it brought a satisfying feeling of vengeance.
But Douma... this person has no emotions. Perhaps he himself couldn't understand why others hated him, when all he wanted was for them to share eternal life with him.
The emotions he displayed were all clumsy imitations.
"However, I want to correct one thing."
"If we are talking about the current Demon Slayer Corps, they still cannot achieve what my intelligence mentioned."
"Upper Rank One and Upper Rank Two—these two demons absolutely cannot be defeated merely by numerical advantage."
Although she hated her former older brother, Mizuki had to admit that he truly possessed great strength.
Aside from Muzan and Yoriichi, the title of strongest is indisputable; even she, as she is now, wouldn't dare claim a guaranteed victory.
As for Douma, that Blood Demon Art... it is overly restrictive for Breathing Technique swordsmen.
Regarding Upper Rank Three, Akaza, she hasn't seen him personally, so she cannot judge, but his strength must also be considerable, otherwise the Flame Hashira would not have died by his hand.
"The current Demon Slayer Corps..." Ubuyashiki muttered, then asked with a smile, "Miss Mizuki, do you have any suggestions?"
Mizuki untied the white cloth covering her face: "I have brought the Demon Slayer Corps three ultimate techniques to defeat Muzan."
'Three ultimate techniques?' Kochou Shinobu turned her head in confusion, only to see the alluring Demon Slayer Mark on Mizuki's face.
Amane Ubuyashiki hesitated and said, "Are you perhaps referring to... the Demon Slayer Mark?"
Slightly surprised that the Demon Slayer Mark had been recorded, Mizuki nodded slightly.
"That's right: the Demon Slayer Mark, the scarlet blade, and the Transparent World."
"These three ultimate techniques are humanity's hope for defeating the demons."
Mizuki's words were completely incomprehensible to everyone. While the Demon Slayer Mark had some records passed down in the Demon Slayer Corps, what were the scarlet blade and Transparent World?
Mizuki didn't keep them guessing, stroking the mark on her cheek: "The so-called Demon Slayer Mark is a method of improving physical fitness. When activated, unusual marks appear on the body's surface, hence the name."
Kochou Shinobu couldn't help but take a second look. She had thought it was a tattoo or some kind of Blood Demon Art.
From Mizuki's profile, the strange red markings curved and extended to her neck, delving deep below her collarbone.
"The scarlet blade is a technique that stimulates the power of the Nichirin Blade. By using immense gripping strength to raise the temperature of the Nichirin Blade, the edge turns red, which can suppress a demon's regeneration."
"And the Transparent World is an ability that grants near-x-ray vision, allowing one to clearly see a demon's body structure and blood flow."
"All three of these abilities are greatly helpful in combat."
"..."
Everyone felt as if they were listening to gibberish.
Records of the Demon Slayer Mark were already scarce, and now there was talk of the scarlet blade and Transparent World—a blade turning red and x-ray vision. If the speaker hadn't been Mizuki, they would have doubted the veracity of the claims.
Are these truly abilities that humans can master?
Amane Ubuyashiki pondered for a moment: "The Demon Slayer Mark—I recall the records stating that those who activate it do not live past the age of twenty-five."
"Yes, because the activation of the Demon Slayer Mark, strictly speaking, is achieved by overdrawing one's life force in exchange for improved combat ability."
Kochou Shinobu's eyes lit up slightly. She hadn't absorbed the first half of the sentence, but she heard the second half clearly.
Ubuyashiki Kagaya asked, "What is the difficulty level for mastering these three ultimate techniques?"
"Not difficult."
"Oh?" Ubuyashiki looked surprised.
He had already mentally prepared himself, knowing that if they were simple, they wouldn't have been lost to history.
"As for the Demon Slayer Mark, I possess it."
"This is an ability that resonates with those around the user. As long as one person masters it, others can gradually learn it."
"The scarlet blade requires immense gripping strength. Those who awaken the Demon Slayer Mark should have the power to master this technique."
"As for the Transparent World... that one is indeed a bit more troublesome."
Mastering the Transparent World is different from the other two; it requires an extremely high understanding of martial arts.
Not to mention fully mastering all three ultimate techniques, at the very least... achieving the Demon Slayer Mark and the scarlet blade is necessary to have a chance of defeating Muzan.
Ubuyashiki smiled: "I see. Miss Mizuki's arrival truly illuminates the path for the future of the Demon Slayer Corps."
"However, the Hashira are currently performing missions outside, so it might take some time to gather them."
Mizuki shook her head: "It's fine. The awakening of the Demon Slayer Mark can be slow if necessary, but I am confident I can have them master it in a short period."
Since awakening the Demon Slayer Mark means not living past twenty-five, if possible, she wants to wait until Tanjirou has fully mastered Sun Breathing before proceeding.
As for how to awaken it...
They simply need to roll around the edge of life and death, and it will naturally awaken.
Resonance doesn't mean they can master it without doing anything; their bodies still need to reach a certain limit.
And she has ten thousand ways to push everyone to their limits.
Ubuyashiki Kagaya estimated that the time was right: "I understand. The three of you must be exhausted from your journey, so I'll trouble Shinobu to arrange your accommodations."
Exhausted from their journey?
They walked here.
After bidding farewell to Ubuyashiki, Kochou Shinobu looked at the three of them and was about to speak when Tamayo interrupted her.
"Miss Kochou, Mizuki told me that you are housing a demon with a clear consciousness. Could you take me to see them?"
Kochou Shinobu was momentarily stunned, then nodded lightly: "Of course."
She was actually quite curious how Tamayo would treat the patient.
Kochou Shinobu looked at Mizuki: "Mizuki, do you want to return to the Butterfly Mansion to rest? It's the same room as before; I've already cleaned it out."
Mizuki shook her head and pulled up the white cloth: "I'll go with you."
Strictly speaking, she was the one who caused this situation, so it wouldn't make sense for her not to follow along.
