When Ratatoskr and his group appeared, the atmosphere at the scene suddenly became quiet.
Although he was the host who invited the other party to negotiate, many Pillar-level members still placed their hands close to the Sun Blade without leaving any trace.
Because Ratatoskr doesn't seem to have much sincerity.
Not only did all of them hide their faces, but their bodies were also covered by black robes, making them look extremely alert.
"Is it because you are too ugly that you dress like this in order not to scare people?" Sanemi Shinazugawa couldn't help but sneer, "Now that you are here, you still have to do this unnecessary thing. Are you guilty or did you not intend to take it seriously from the beginning?"
"Of course we can take off this outfit, but do you have the guts to take off your Nichirin sword?" Yushiro, who was wearing a one-eyed demon mask, snorted coldly, "Our relationship is not pally to begin with. Since both sides are wary, let's not waste our time talking."
As soon as they met, the hot-tempered guys from the two organizations started fighting.
Just when they were about to say something, Kotori Itsuka and Ubuyashiki Kyouya raised their hands almost at the same time, stopping their actions which were making the air even more tense.
"Improving the relationship between the two organizations is the purpose of this meeting." Kagaya Ubuyashiki said softly, "We don't know each other, so it's natural for both sides to be wary. Saniya, don't be too tough."
"yes..."
After hearing what the lord he served said, Sanemi Shinazugawa, who originally wanted to show a warning to Ratatoskr, had to shut his mouth.
But, in fact, he was not wrong.
Ratatoskr was indeed guilty.
To be more precise, it was Kotori Itsuka who felt guilty.
Looking at Kyōjurō Rengoku who was very conspicuous standing among the crowd, Kotori Itsuka coughed lightly twice and adjusted her voice.
Originally, she just wore a mask to hide her face.
But in today's meeting, she knew that Kyōjurō Rengoku would definitely attend, so she temporarily put on a cloak to cover her body.
Otherwise, even if he couldn't see her face, based on Kyōjurō Rengoku understanding of his sister, he would definitely realize that the leader of Ratatoskr was his sister the moment Kotori Itsuka appeared.
Precisely because he didn't want Kyōjurō Rengoku to guess this, even Yushiro followed suit and put on a cloak and a mask.
After all, Yushiro and Kyōjurō Rengoku had met once.
And because he mistook the other party for Kotori Itsuka suitor, Kyōjurō Rengoku was deeply impressed by him.
However, there are only two people in the organization who hide their identities, while the others reveal their identities openly. Anyone with a little bit of intelligence would realize that the reason why Kotori Itsuka and Yushiro hide their identities is that they don't want the Demon Slayer Corps to recognize them.
Following this line of reasoning, the members of the Demon Slayer Corps might have guessed that one of the Pillars present might have met them before.
The Demon Slayer Corps' intelligence capabilities are not weak. If they were allowed to guess this and continue investigating, perhaps Kotori Itsukatrue identity would really be exposed.
Therefore, in order to cover for Kotori Itsuka and Yushiro, the remaining four also put on cloaks and masks. The purpose was to make the Demon Slayer Corps think that this attire was a requirement of the organization.
Just like the Demon Slayer Corps have a uniform.
However, even after achieving this, Kyōjurō Rengoku in the crowd still sensed something was wrong.
"I feel like I've heard these two people's voices somewhere before."
His hands were on his waist, as if he would draw his knife immediately if there was any unusual movement, but his mind was thinking about other things.
Even though both Kotori Itsuka and Yushiro changed their voices, the changes were not that big, and the falsetto they used was very obvious, and anyone who listened could tell that they were deliberately speaking in a low voice.
Staring at Ratatoskr and his group standing on the wall, especially the girl in the middle wearing a demon mask, he inexplicably felt a little familiar.
But I can't remember where I have seen it.
He really had no idea, so Kyōjurō Rengoku had to put aside the doubts in his heart.
Seeing that he did not recognize her identity at the first sight, Kotori Itsuka breathed a sigh of relief.
They came here today to discuss cooperation with the Demon Slayer Corps.
If her identity was exposed here, trouble would surely ensue.
After all, most of the Pillars hate demons.
In the original work, when the Pillars were judging, Water Pillar Tomioka Giyu was suspected of being a traitor by others simply because his junior fellow apprentice was hiding a Demons.
If these guys knew that the sister of Flame Pillar Kyōjurō Rengoku was a Demons, they would definitely make a huge fuss.
Taking a deep breath, Kotori Itsuka moved and came to the front yard of the mansion.
Keeping a certain distance so that both of them felt safe, she and Kagaya Ubuyashiki looked at each other.
"Then let's get straight to the point."
As the leader of the organization, Kotori Itsuka asked without hesitation: "You invited us here to cooperate, right?"
"That's right." Kagaya Ubuyashiki nodded slightly. "Since Ratatoskr goal is to end the war between humans and demons, the fastest way is obviously to kill Muzan Kibutsuji. This coincides with the mission of the Demon Slayer Corps."
"I actually agree with cooperation." Kotori Itsuka glanced at the pillar-level members behind Kagaya Ubuyashiki, "But there is one thing I need to explain first."
"Please go ahead."
"The demons who joined Ratatoskr are all demons who have escaped from the control of Muzan Kibutai, so even if he dies, we will not die." Kotori Itsuka said lightly, "So, if you are thinking that after you defeat Muzan Kibutai, we will die like other demons, I advise you to reconsider."
Upon hearing this, the expressions of many Pillar-level members changed.
To be fair, none of them wanted to cooperate with the Demons.
Everyone who joins the Demon Slayer Corps has more or less had a grudge against demons. Perhaps a relative was killed, or perhaps a pal was killed. The hatred for demons and Muzan Kibutsuji drives them to devote their entire lives to slaying demons, with the ultimate goal of making all demons disappear.
One of the reasons why they are willing to cooperate with Ratatoskr is indeed because when Muzan is defeated, all demons will die, including those in Ratatoskr.
But now, the leader of Ratatoskr said that they were not affected by Muzan.
Even if Kibutsu died tragically, they would still be alive.
This is something the Demon Slayer Corps needs to reconsider.
Looking at the silent Kagaya Ubuyashiki and a group of Pillar-level members with different expressions, Kotori Itsuka chuckled twice.
Then, he looked at Tamayo who was wearing a Yasha mask and gave her a hint to act.
So, Tamayo stepped forward and took out two bottles of medicine from his sleeves.
"Don't worry about it." Tamayo said, holding up two bottles of medicine, "We are not man-eating Demons. Under the conditioning of medicine, we only need a small amount of human blood to maintain our sanity. We don't need to eat human flesh."
"Ha, there's no need for a man-eating Demons." Sanemi Shinazugawa couldn't help but speak again, "Do you think we are children? Do you think we can believe such a clumsy lie?"
"I'm just stating the facts," Tamayo said calmly, "Besides, whether or not we gain your trust doesn't make much difference to us."
"What about the other potion?"
Kagaya Ubuyashiki did not dwell on this question, but looked at the other potion in Tamayo hand.
Although it does sound incredible that a Demons does not eat people, Giyu Tomioka has always claimed that Tanjiro Kamado sister needs to eat people to remain sane after becoming a demon. If he is not lying, then this statement is not difficult to accept.
Besides, if the two organizations really plan to join forces next, they will inevitably stay together for a long time.
By then, the Demon Slayer Corps will naturally know about Rata and will start to talk about the tomb-piercing hook.
There is no point in telling lies that can be easily exposed.
What Kagaya Ubuyashiki is more curious about now is the other potion.
"If the effect of one of the potions is to change the Demons diet, then what is the effect of the other potion?"
"I'm glad you asked," Tamayo replied calmly, "The second one is a potion that can turn a Demons back into a human."
"What?!"
"Can Demons really turn back into humans?"
"You must be kidding..."
Upon hearing this breaking news, not only the Pillar-level members, but even the usually calm Kagaya Ubuyashiki showed a hint of surprise on his face.
Demons are all transformed from humans.
But in these thousand years, no one has ever heard of a Demons being able to turn back into a human.
Several doctors in the Demon Slayer Corps have tried to make an antidote to turn demons back into humans, but they all failed for various reasons.
Now that Tamayo has really put the finished product in front of everyone, it has naturally caused a huge response.
In the original work, Tamayo also successfully developed an antidote that can turn Demons back into humans.
But, it was already close to the finale.
But in this world, due to the activeness of Kotori Itsuka, Tamayo collected more demon blood faster, and the research speed naturally accelerated.
"If this is true, then Tanjiro, your sister is..."
Among the crowd, a gleam of light flashed in the eyes of the silent Tomioka Giyuu, and a hint of melancholy appeared in his calm voice.
As the first person to meet Tanjiro Kamado and also the senior who introduced him to the Demon Slayer Corps, Giyu Tomioka naturally knew Tanjiro Kamado two biggest wishes.
First, to avenge the dead family members.
The second is to find a way to turn Nezuko back into a human.
"Yes, Brother, Nezuko can turn back into a human at any time."
Tanjiro Kamado, wearing a will-o'-the-wisp mask, answered, his tone mixed with excitement and complexity that could not be concealed: "But Ratatoskr needs manpower now, and if Nezuko turns back into a human now, she will not be able to participate in the battle with Muzan in the future, so I have not let Nezuko take this potion for the time being."
The discussion continued for some time.
Afterwards, Tamayo lightly threw the two potions to the Demon Slayer Corps.
"If you don't believe me, you can try the effects of these two potions yourself."
"Then we will respectfully obey your orders."
Shinobu Kocho took the two potions.
She is the person with the most say in pharmacology in the Demon Slayer Corps, so the verification work is naturally done by her.
However, although it is called verification, in fact, everyone in the Demon Slayer Corps has already believed it in their hearts.
After all, the finished potion was given directly to them, and they only needed to catch a Demons to test it to find out the effect.
At this point, even the Pillar-level members who were most hostile to Ratatoskr no longer held hostility towards them.
"Well, I think now we can actually discuss how to defeat Muzan?"
The Demon Slayer Corps finally let down their guard, and Kotori Itsuka asked.
"Of course."
Kagaya Ubuyashiki nodded.
The two parties formally confirmed their cooperative relationship.
After gaining the Demon Slayer Corps, an ally who kept their promise and would not betray them, Kotori Itsuka told them the plan that she had previously discussed with Tanjiro Kamado to lure Muzan Kibutsuji to appear.
After being dumped with countless important information, the more the Demon Slayer Corps listened, the more they felt that Ratatoskr was a hidden talent.
"If that lady is really Muzan former assistant, and there are demons among you who are immune to sunlight, and even have potions that can remove curses on demons and turn them into humans, I think if I were Muzan, I would also attack you."
Digesting the large amount of information he just heard, Kagaya Ubuyashiki said thoughtfully: "To be honest, I originally planned to use myself as bait to lure Muzan out, but you are obviously more attractive... This is a very dangerous plan, are you sure you want to do this?"
"It's not that dangerous. As long as I can find that rat who is hiding his head but showing his tail, I can defeat him by myself."
Although no one knew where the leader of Ratatoskr got his confidence from, they were all still dazed by the information they had just received, and no one came to refute it for a while.
"What I'm most worried about is that we lure him out, but he runs away." There was a hint of seriousness in Kotori Itsuka tone, "You know, he is a cautious and paranoid person. If the lure plan fails once, it will never succeed again."
"The nine pillars of the Demon Slayer Corps, plus you, still can't stop him?"
"It's difficult." Kotori Itsuka shook her head. "He has a demon named Nakime under his command. She can control a different dimension called Infinite Castle. As long as Wuzan wants, she can escape through this different dimension at any time."
"There is such a thing..." Ubuyashiki Kazuya frowned slightly.
The plan to lure Muzan Kibutsuji to appear can be said to be perfect.
As long as the information is leaked, Muzan will definitely hunt down Ratatoskr madly.
But even if he is lured out, whether he can be defeated is another matter.
But even if we can defeat him and prevent him from escaping, that's another matter.
If the problem can only be solved, neither Kotori Itsuka nor Kagaya Ubuyashiki have a good solution.
"Commander, you just said that the Demons named Nakime can control the different dimension called Infinite Castle, right?"
At this moment, Dazai Osamu, who had been silent all this time, suddenly asked, "Is that different space created by the blood demon technique?"
"yes."
"Well, I think I have a way to solve it." Dazai Osamu patted his chest, "During the time you were away, in order to enhance my strength, I drank a lot of the demon blood that you and Tanjiro had collected before, and awakened my own blood demon art."
"You? Blood Demon Art?" Kotori Itsuka expression became a little strange, "What is the ability of your blood demon Art?"
"Within the range of my Blood Demon Art, all other Demons' Blood Art will lose its effect."
As Dazai Osamu mind moved, a faint blood mist appeared beside him and spread throughout the mansion.
"I call it No Longer Human."
