3rd POV. Butterfly Estate.

After Sora argued with Kanae about him staying at the Ubuyashiki Estate, the Uchiha conceded as he doesn't want to be lectured by Kanae, to the point that it will become worse if Shinobu tags along and endlessly nag at him.

Sora immediately went to the room where Tanjiro is staying.

Tanjiro: Nii-san!? What's wrong? Did something happened?

Sora: Kinda.

Tanjiro: Uh......

Sora: Kanae saw me attempting to jump over the fence.....

Tanjiro: Nii-san.......

Tanjiro: You don't have to hide anymore from the Hashira......

Tanjiro: Although, you said you beat up Shinazugawa-san.....

Sora: He deserved it for hurting Nezuko, I won't forgive him.

Tanjiro: Right.

Tanjiro: But nii-san, everything is alright now. You don't have to be scared anymore.

Tanjiro: You don't have to sleep full of nightmares now.

Sora: I know.

Sora: I should thank you, as well.

Sora: If I haven't met you and Nezuko on that day.......

Sora: Maybe I wouldn't be able to embark on this journey of redemption.

Tanjiro: Mm.

Tanjiro: And I also have a better understanding of what you went through.

Tanjiro: If I was only strong enough to help you in any way I can—

Sora: Tanjiro, you're already strong.

Sora: For Nezuko, for moving forward as well. Even retaining your kindness......

Tanjiro: Nii-san, don't be too hard on yourself.

Tanjiro: You kept smiling, even though you're hurting inside.

Tanjiro: But that won't sit right with Nezuko and I.

Tanjiro: That is the reason why I wanted we always wanted to help you as much as we can.

Tanjiro: And the scent of kindness.....

Tanjiro: As clear as the blue sky......

Tanjiro: It never faded.

Sora: Thank you, Tanjiro.

Sora lay on the bed beside Tanjiro's bed......

Sora: I definitely need to rest up.

Sora: You too, Tanjiro.

Tanjiro: I do hope your prepared for the recovery training.

Sora: Haha......yeah......

Sora: Goodnight.

The next day, Sora woke up when he found out that Tanjiro is talking with a Kakushi.

Sora: Morning.

Tanjiro: Ah, nii-san. Good morning.

Kakushi: Uh, I was wondering who is the hell is the guy sleeping on the other bed.

Sora: Ah.

Sora: I'm Uchiha Sora, Tanjiro's adoptive brother.

Gotou: Nice to meet you, Sora. I'm Gotou, a member of the Kakushi.

Sora: Nice to meet you too.

Suddenly, a swordsmith entered the room, whom Tanjiro recognized as Haganezuka.

Tanjiro: Haganezuka-san!

Haganezuka walked towards Tanjiro as Gotou offered his seat.

Haganezuka gave a sword to Tanjiro, with the flame shaped hilt just like Kyojuro's.

What surprised the others is Haganezuka gave another sword and points at Sora.

Sora: Me?

Haganezuka: *nods*

Tanjiro hands over the sword to Sora.

Sora: Wait, I still have the same sword that I got from the village.......what is this?

Haganezuka: That sword......

Haganezuka: The chief's gift of gratitude for saving us......

Haganezuka: A gift.....on behalf of the swordsmith village.

Sora: I see.

Sora meditated despite the noise of Haganezuka lashing out at Tanjiro.

Sora: No wonder why Tanjiro is kinda afraid of Haganezuka.

Sora sheathed the new blade.

And just like Tanjiro, the blade turned into black.

However, there is an inscribed character written on it, and it says, "Amaterasu no Tsurugi."

Sora: Amaterasu no Tsurugi? Named after Amaterasu-sama?

Gotou: Oh, that's nice. Considering that Nichirin Swords are made from special ores that can absorb sunlight.

Tanjiro: Nii-san, you said that Amaterasu-sama is the ancestor of the Uchiha Clan, right?

Sora: Yes. The very reason why my clan is blessed with the Sharingan, because originally, we are the guardians of the land.

Sora: To protect this country from evil.

Sora: That is the purpose of the Uchiha. The flame that burns in our hearts.

Sora: I guess it is an honor to name this sword, after my ancestor.

Afterwards, Haganezuka left.

Suddenly, Inosuke destroyed the window.

Gotou: WAAAAAGGGGHHH!

Sora: What the!? Inosuke!?

Tanjiro: Why'd you break the window!?

Gotou: YOU DUMBASS! SHINOBU-SAMA WILL KILL YOU!

Inosuke: WRRRRRRRYYYYYYY!

Inosuke: Stronger! Stronger! Stronger!

Inosuke: WE'RE GONNA HAVE A SUPER HARD TRAINING SESSION NOW!

Inosuke: Lots of strong people are coming together to train.....and some hubble dubble I can't remember what they're talking about!

Tanjiro: What are you talking about?

Inosuke: NO CLUE AT ALL!

Sora: *face palm*

Sora: As expected.....Inosuke will be Inosuke.

Sora: Anyways, I want to have a walk and eat.

Sora: Genya, wanna join me have some breakfast?

Sora noticed Genya also lying on the other bed.

Genya: How did he even knew I was here!? This guy has some crazy senses.

Genya: I'll pass, Sora-san. I want to rest for a bit.

Sora: Okay.

Sora went out of his room and walked around the Butterfly Estate.

It was only a short walk and the fact that one even noticed him because Sora is not creating any noise with his footsteps, he remembered the time where Sasuke taught him about that technique when he was being taught to the Hinokami Kagura.

Sora immediately went back to the room after he got some onigiris and ate it.

Since he hasn't recovered completely yet, Sora did nothing but sleep.

A few moments later, Kanae entered the room to check on Sora.

Kanae: So, he's asleep.

Kanae: I can't blame him. He's been so tired.

Kanae: Physically, mentally, spiritually, and emotionally.

Tanjiro: Nii-san really went through a lot.

Tanjiro: I still can't believe he went through all of that.....just to protect the people precious to him.

Kanae: Tanjiro-kun, I want to thank you for support Sora throughout those years.

Tanjiro: I guess, he also supported me in return as well. Being a wise brother and all.

Tanjiro: It's also been years since I last saw him sleep like that.

Kanae: He looks so peaceful, he sleeps like a baby.

Tanjiro: Haha. I know. That is what happens when nii-san is very exhausted from work.

Tanjiro: Whenever that happens, he would always go straight to sleep.

Kanae: Even though Sora is a second born, I always wondered how did he became such a wonderful brother to those younger than him.

Kanae: And the answer is none other than his biological brother, Sasuke-niisan.

Tanjiro: He would always tell stories about his brother sometimes.

Kanae: I know my hatred for him during all those years were misguided.....

Kanae: In the end, he's still the Sora that I know and love.

Tanjiro: Huh?

Kanae: Huh?

Tanjiro: Kanae-san, did you just?

Kanae: ..........!

Kanae: Please, forget about that last part.

Tanjiro: O-Okay.......

Kanae: Anyways.....

Kanae: Tanjiro-kun, can I ask you something?

Tanjiro: Yes, what is it?

Kanae: I just noticed that Sora's eyes are much darker in blue. So I was wondering what could've happened.

Tanjiro: Hmmmmm, how will I explain this......

Tanjiro: It is because he almost got blind.

Kanae: Got blind? From the overusage of his Mangekyo Sharingan?

Tanjiro: Yes. But don't worry.

Tanjiro: He got an eye transplant.

Kanae: Eye transplant? From who?

Tanjiro: Nii-san told me that the eyes he's using now......

Tanjiro: Is none other than Sasuke-san's eyes.

Kanae: What?

Tanjiro: That is what he said.

Tanjiro: But thanks to that, he can now see clearly again.

Kanae: So that's what happened.

Kanae: I guess we should let him sleep.

Kanae: He earned himself a good sleep.

Tanjiro: Yeah.

Sora really took the chance to finally get some rest. To the point that he slept like a log for the past few days.

When Zenitsu came to drop by and informed Tanjiro about the ongoing Hashira Training......

Tanjiro told Zenitsu about the events that transpired after the events of the Red Light District, until Sora finally regaining the final fragment of his memory and revealing the dark truth about his nightmare.

Zenitsu: I see......

Zenitsu: So that's the hidden sound that I can hear from Sora-san. It was almost too quiet but whenever I try to focus listening to it.....

Zenitsu: My ears will began to get hurt as if telling me not to go any further.

Zenitsu: To think that Sora-san went through all of that......

Zenitsu: I do hope that after all of this is over......

Zenitsu: He may find happiness.

Tanjiro: That's why, once Nezuko reverted back to become a human......

Tanjiro: We'll help nii-san in whatever way we can.

Tanjiro: We can't let him work all by himself after all.

Zenitsu: That's really nice to hear.

Zenitsu: Tell Sora-san I said hi when he wakes up but.....

Zenitsu: I guess he's really taking his sweet time to sleep.

Tanjiro: That would be one of the most peaceful sleeps that he had after all these years.

Zenitsu: Right.

Zenitsu and Tanjiro talked for a while before the yellow haired swordsman left.

Coincidentally, Sora just woke up from sleep.

Sora: *yawn*

Sora: Good morning.......

Tanjiro: Good morning, nii-san. Zenitsu just came by and he already left.

Sora: I see.

Tanjiro: He said hi.

Sora: How is he doing?

Tanjiro: I don't know but apparently, the Demon Slayers are conducting the Hashira Training.

Sora: Well, ever since demons had stopped appearing when the news of Nezuko being the first demon to conquer the Sun.......

Sora: We all knew what is going to happen. The battle is now going to be centered around Nezuko.

Sora: That is the reason why they hid Nezuko in a very secluded place.

Sora: All the more reason to be much stronger than before.

The door of the room opened to reveal Shinobu.

Shinobu: Oh, Tanjiro-kun, Sora-niisan.

Tanjiro: Ah, Shinobu-san, nii-san just woke up.

Sora: Right.

Sora properly sat up on the bed as Shinobu examines Sora.

Shinobu: I'm surprised that you didn't had any wounds.

Sora: But my body is exhausted as hell because I haven't really got any proper rest ever since the demon invasion at the Swordsmith Village.

Shinobu: Just what the heck happened to you? We learned from Tanjiro-kun that you fought Upper Six all by YOURSELF!

Shinobu: Are you insane!?

Sora: For someone who wished me to burn in hell......

Shinobu: Shut up! You owe me mochi!

Sora: Why can't you buy them yourself?

Shinobu: You promised me 12 years ago! A story about the origin of the Hinokami Kagura while eating mochi.

Sora: I can't believe you remembered that.

Shinobu: Of course I will. That was, after all, the very last time that I saw you before you disappeared.

Sora: Right. I'm sorry.

Shinobu: To think that Misaki-obasan and Sasuke-niisan died on that night.

Shinobu: Also, Sora, did you know? About Misaki-obasan?

Sora: *nods quietly*

Sora: I learned it in full detail when I read my brother's journal when I visited Oyakata-sama back then.

Sora: He kept the my brother's journal.

Sora: I guess if something happens to my brother, Oyakata-sama had something to at least impart to me when I have to learn more about my brother.

Sora: I already noticed that my mother is struggling to keep up with some physical activities.

Sora: The very same reason why I always wanted to help her and will always tell her to take a break because I can see that she got tired quite often.

Shinobu: ........

Sora: If I knew about my mother's illness before, if I knew that she would certainly die for it.....if I wasn't so naïve.

Sora: Then maybe I could've prepare to say my last goodbyes to her.

Sora: But it never happened because the very first thing that we saw when we came back to our home village.....

Sora: Outside.....just near the village's border......

Sora: Our mother's corpse on her pool of blood.

Sora: She's already dead when nii-san and I found her.

Sora: That was the very first time that I felt extreme sadness and pain from losing a love one.

Sora: And that even lead me to awakening my Sharingan.

Tanjiro: Then, when you tried to find any survivors......

Tanjiro: All of them are dead?

Sora: Yes. All buildings almost destroyed, some of the houses already caught in fire, some of the houses just crumbled down completely.

Sora: To think that the village where I was born and raised, was reduced to rubble by one just one man.

Sora: Not to mention, even with the Uchiha fighting Muzan, they weren't even a match for him.

Sora: And I can see the reason.

Sora: I'm guessing that during the end of the Meiji Era, the decline of Sharingan users in the clan became evident.

Sora: According to nii-san's record......

Sora: He said there that the Sharingan users of the Uchiha Clan began to dwindle.

Sora: I need to remind you that the Uchiha Clan and the Ubuyashiki Family had a long history of fighting Muzan together.

Sora: But since the history of my clan's past is filled with so many undesirable events......

Sora: The Uchiha decided to vanish and hide, lived in a unknown village.

Sora: Nii-san also said that the priest who sensed about the original demon being born in a certain family.....

Sora: The priest told them to dedicate their souls in defeating the demon.

Sora: And the priest even feared that the demon could somehow spell the destruction of the country or even worse, of all humanity, he suggested to seek out......

Sora: "The Sacred Protectors of the Land."

Shinobu: The Sacred Protectors of the Land?

Tanjiro: Nii-san, are you talking about?

Sora: The Uchiha Clan, the clan who descended from Amaterasu-sama through her descendant, Indra.

Sora: Also, I know you two may find this funny but, I had a dream while I'm asleep.

Tanjiro: A dream?

Sora: Yes.

Sora: And in that dream......

Sora: It seems like I dreamt about a man who protected humans from demons.

Sora: A man who hunted down Muzan, and I believe that based from their clothes and the situation of the social issues during that time.....

Sora: I believe it was around the Sengoku Period.

Tanjiro: The Sengoku Period?

Sora: Yes.

Sora: I first saw that man as a boy. He grew up kind and always sad because his friend died from an illness.

Sora: That is where I saw that he is an Uchiha because he awakened his Sharingan on a very young age, around 6 years old, I think.

Tanjiro: That young!?

Sora: Yes.

Sora: When the young boy was crying due to the death of his friend, his Sharingan still active......

Sora: A gentle light descended upon him and when the little boy looked up, there is a beautiful and gentle woman as if descending from the sky.

Sora: A lady clad in white kimono, pristine white hair, and eyes as red like a ruby.

Sora: The boy was just stunned by the aura that the mysterious lady emits

Sora: The boy's amazement was turned to fear because of thinking what the mysterious figure would do to him.

Sora: However, the lady smiled gently upon the boy, and she gently said to wipe his tears.

Sora: For the world will not stop no matter how much he cries. All he had to do is to slowly get over the death of his friend.

Sora: And use his talent, his divine eyes to help people.

Sora: That boy finally deduced the figure and it was none other than Amaterasu-sama.

Shinobu: What!? You mean, in your dream, you saw Amaterasu-sama!?

Tanjiro: The goddess of the sun!?

Sora: And before she parted with the boy, she said these words:

Sora: "Your eyes are born out of love. The Uchiha, my descendants through my descendant, Indra, who deeply loved this land and the people, that is the reason why I blessed them with special eyes."

Sora: "The eyes that reflects one heart. The eyes that watched over and defeat any evil that threatens this lands."

Sora: "The Sharingan, is not a proof of one's weakness but of strength. A testanent to an Uchiha's strength, love."

Tanjiro: Love?

Sora: Thinking about it now.

Sora: I think I awakened my Sharingan, not only out of grief, but out of love for my mother.

Sora: As for the Mangekyo Sharingan, the sin that I carried.......

Sora: Was also born out love to someone very close to me.

Sora: That is the reason why......

Shinobu: I see.

Tanjiro: So, out of love......

Tanjiro: Is that the reason why you somehow endured?

Sora: Yes.

Sora: Anyways, I want to have breakfast.

Shinobu: Aoi just finished cooking.

Sora: All right.

Shinobu: Are you sure you're okay to stand up now?

Sora: Don't worry, I did nothing but lie in bed for the past few days. I want to have a breather.

Shinobu: I guess that is also good.

After checking up on their conditions, Shinobu left to attend to her other patients.

Meanwhile, Kagami, Sora's current crow, arrived and delivered a letter from Kagaya himself.

Sora picks the letter.

Sora: Tanjiro, if I remember correctly, Tomioka-san is the first demon slayer that you met, right?

Tanjiro: Yes. He's the one who introduced me to Urokodaki-san and began my journey as a demon slayer, to find a cure for Nezuko.

Tanjiro: Why? Is there something wrong?

Sora: Oyakata-sama said here that we have to convince him to train alongside the others.

Sora: Let me read the letter.

Sora: "First of all, Sora, I'm overjoyed when I heard the news from Amane. You finally broke free from your suffering."

Sora: "I'm sure, that you're finally at peace. You deserve it, for all the hard work that you've done."

Sora: "Tanjiro, Sora, I also wanted to ask how are your injuries."

Tanjiro and Sora smiled.

Sora: Haha, he really thought
