Time passed, and in the blink of an eye, the next day arrived.
When Cain woke up from his sleep, changed his clothes, and walked to the entrance of the secret chamber,
all the Hashira, including Uzui Tengen, had already gathered there.
"Cain, you woke up way too late."
"It's you guys who woke up too early."
Cain replied with completely justified confidence.
Waking up at six in the morning was already quite impressive. He had never been this diligent back when he was attending school.
"Are the restraint tools ready?"
"They're ready."
Uzui Tengen stepped aside slightly, revealing a pile of restraint tools placed behind him.
"Then let's begin."
Cain and the others carried the tools and entered the secret chamber.
As the channels through which Kibutsuji Muzan could receive information, Daki and Gyutaro needed to be brought back to the Demon Slayer Corps together.
After blindfolding them, plugging their ears, and sealing their mouths to ensure their location could not be exposed during the journey, Cain and the others departed from the Rengoku Residence and began their return trip.
The Rengoku Residence was located on the outskirts of Tokyo, not very far from the headquarters of the Demon Slayer Corps.
After traveling for the entire morning, the group soon arrived at their destination.
"Cain, you should go see the Master first. We'll take care of these two."
Since Cain needed to negotiate with Ubuyashiki Kagaya, Uzui Tengen and the others stopped naturally.
The group split into two.
Uzui Tengen and the others escorted Daki and Gyutaro to the small confinement chamber, while Cain headed alone toward the Ubuyashiki Residence.
It was June, and the late-blooming cherry blossoms were in full bloom.
Soft pink petals drifted through the wind, falling onto the bluestone path in the courtyard.
At the end of the stone path stood Ubuyashiki Kagaya, quietly supported by Ubuyashiki Amane.
"Cain, you have returned."
A gentle smile appeared on Ubuyashiki Kagaya's face.
"I have already heard about the situation in Tokyo."
"Thanks to your plan, we achieved such remarkable results."
"It is only a temporary victory. If we cannot eliminate Kibutsuji Muzan, none of this will matter."
"That's correct. Kibutsuji Muzan must be killed."
Ubuyashiki Kagaya nodded slightly, agreeing with Cain's words.
Kibutsuji Muzan was the origin of all demons.
If he could not be eliminated, the empty positions among the Upper Rank Demons would inevitably be filled again within a few years.
"Cain, I heard that you issued a challenge to Kibutsuji Muzan. How confident are you about this battle?"
"For now, ten percent. If Tamayo can assist us, the chances may improve slightly."
"I see."
Ubuyashiki Kagaya fell into brief contemplation.
A moment later, as if having made a decision, he took out a letter from within his robe.
"Cain, there is something I must apologize for. The truth is that I lied to you about Tamayo."
"I know."
"I have known for a long time... Huh?"
Ubuyashiki Kagaya, who had been preparing to confess everything, suddenly froze.
Looking at the black-haired youth before him, an extremely rare expression of confusion appeared on his face.
"You know?"
"That's right. I know that you are acquainted with Tamayo and that you have been pretending to have no contact with her."
Cain replied calmly.
In the original story, when Tanjiro first met Ubuyashiki Kagaya during the Hashira meeting, Kagaya had asked Tanjiro to send his regards to Tamayo.
Later, during the preparations for the final battle, it was also Ubuyashiki Kagaya who invited Tamayo to cooperate with Kochō Shinobu to set a trap for Kibutsuji Muzan despite considerable opposition.
Knowing these two facts, it would have been strange for Cain to believe that Ubuyashiki Kagaya and Tamayo were strangers.
"Actually, I completely understand your concerns. My appearance was far too sudden."
Seeing that Ubuyashiki Kagaya had mentally prepared himself to confess everything, Cain also decided to speak honestly.
"If I were in your position and suddenly encountered someone who knew the secrets of the Upper Rank Demons and Kibutsuji Muzan, I would also suspect that person might be a spy sent by Kibutsuji Muzan."
"If I had not personally led the team to capture an Upper Rank alive and eliminate two Upper Rank Demons this time, you probably would have kept Tamayo's information hidden forever, correct?"
"...I apologize."
"There is no need to apologize. Instead, aren't you curious about where I obtained this information?"
"If you are willing to tell me, I am indeed very curious."
Ubuyashiki Kagaya looked directly at Cain.
"To be honest, I had someone investigate your background."
"Before you were rescued by the former Thunder Hashira, Jigoro Kuwajima, you were wandering through the slums."
"In such circumstances, how did you learn the secrets of Kibutsuji Muzan and the Upper Rank Demons? And how did you know that I was in contact with Miss Tamayo?"
"The answer is very simple."
Under Ubuyashiki Kagaya's gaze, a powerful and intimidating aura gradually emerged from the black-haired youth.
"I am a god."
"...A god?"
"That's right! I am god!"
Cain raised his palm as the State of Selflessness and Current Propulsion were activated simultaneously. Brilliant golden lightning burst forth and crackled through the air.
"Although I have only recently awakened, I have already recovered a portion of my divine authority."
"Through this authority, I have learned many hidden secrets, including those concerning Kibutsuji Muzan and the Demon Slayer Corps."
"..."
Ubuyashiki Kagaya fell silent.
As an ordinary human being, Cain's words certainly did not sound like something a normal person would say.
If this had been any other situation, he would probably have summoned Kanae immediately to examine Cain's mental condition and determine whether he had accidentally eaten the wrong mushrooms.
But now...
As he stared at the dazzling golden lightning dancing in Cain's palm, Ubuyashiki Kagaya felt his thoughts becoming increasingly disordered.
Ubuyashiki Kagaya: 0.o?
Do gods actually exist in this world?
"Gods do exist."
As if reading Ubuyashiki Kagaya's thoughts, Cain spoke again.
"You know about Tsugikuni Yoriichi, correct?"
"Of course."
Ubuyashiki Kagaya nodded.
"The creator of Sun Breathing. I have heard that he once pushed Kibutsuji Muzan to the brink of death."
"Tsugikuni Yoriichi was a god as well. A reincarnated god who lost his memories, just like me."
"However, his luck was unfortunate. He never awakened his divine memories before his death and instead entered the next cycle of reincarnation."
"This... is that truly the case?"
Ubuyashiki Kagaya frowned slightly.
To be honest, Cain's explanation sounded somewhat unbelievable, yet when compared with reality it also felt strangely reasonable.
What kind of existence was Tsugikuni Yoriichi?
According to the records, he was a peerless prodigy who defeated an experienced samurai the very first time he held a sword.
Even his natural breathing resembled the Sun Breathing Technique.
During his lifetime, Kibutsuji Muzan disappeared entirely for hundreds of years and only reemerged after Tsugikuni Yoriichi passed away.
For such a being that completely defied common sense, describing him as a god who failed to awaken his memories almost seemed logical.
Recalling the intelligence regarding Tsugikuni Yoriichi recorded by the Demon Slayer Corps and staring at the lightning dancing in Cain's hand, Ubuyashiki Kagaya gradually began to accept Cain's explanation.
"Cain... no, Divine One."
"Thank you for being willing to join the Demon Slayer Corps and assist us in eliminating Kibutsuji Muzan."
"On behalf of the Demon Slayer Corps and the Ubuyashiki Clan, I express my sincere gratitude for this kindness."
"There is no need for thanks. I have my own reasons for helping you deal with Muzan."
"Please speak, Divine One."
"I require the formula for the Evolution Potion."
"Evolution Potion?"
"Simply put, it is the medicine that transformed Kibutsuji Muzan into a demon. Naturally, I require the complete formula."
"This..."
Ubuyashiki Kagaya frowned slightly.
It was as if a bucket of cold water had been poured over him. The conviction he had just formed moments ago quickly cooled, and his mind regained clarity.
"Divine One, you are the reincarnation of a god. Why would you require such an evil thing?"
"Evil? That is merely your own prejudice."
Cain did not react to the sudden shift in Ubuyashiki Kagaya's attitude. His tone remained calm and steady.
"A kind person who gains power will use that power to protect and help the weak."
"An evil person who gains power will use that power to dominate and enslave the weak."
"Power itself is neither evil nor righteous. What determines whether something becomes evil or just has always been the person who wields it."
"Ubuyashiki Kagaya, as someone who stands at the top of this society, you should understand this better than most."
"The human heart is far more terrifying than any demon."
T/N- Muzan became demon due to the medicine derived from blue spider lily, since author is refering it as evolution potion, we'll go with that.
Cain hasn't been to Naruto world yet, but he surely excels at bullshit no-jutsu.
