3rd POV. Four Months after the Infinity Train Incident.

Four months have passed following the Infinity Train Incident......

Tanjiro, Zenitsu, and Inosuke are training under Kyojuro at the Butterfly Estate.

Meanwhile for Sora, now that his identity was exposed.....

He is currently in hiding within the Rengoku Residence. He is helping with everything that they need and ever since Sora arrived, he helped the Rengoku Brothers to get their father back on the right path.

The trio became busy while they took their missions in between of their training sessions.

As much as Sora wanted to join Tanjiro, he can't as he fears that they may encounter more demon slayers.

Sora rather preferred to train on his own. Like going to the forest, practicing his forms.

Like the Hinokami Kagura or rather, he preferred calling it now as Breath of the Sun when he learned of its true name.

Sora: Hi no Kokyu......(Breath of the Sun)

Sora: Enbu (Dance)

Sora: Hekira no Ten (Clear Blue Sky!)

Sora: Retsujitsu Kokyo (Raging Sun!)

Sora: Shakkotsu En'yo (Burning Bones, Summer Sun)

Sora: Shayo Tenshin (Setting Sun Transformation)

Sora: Hirin Kagero (Solar Heat Haze)

Sora: Kiki Onko (Beneficient Radiance)

Sora: Yokatotsu (Sunflower Thrust)

Sora: Nichiun no Ryu Kaburimai (Dragon Sun Halo Head Dance)

Sora: Fire Wheel (Kasha)

Sora: Gen'nichi Ko (Fake Rainbow)

Sora: Enbu (Flame Dance)

After performing all Twelve Forms in succession.......Sora controlled his breathing.

He finally connected the dots that the Hinokami Kagura dance that he knew is actually the Breath of the Sun.

Sora: To think that a kagura dance was used.......

Sora: Not to mention, performing it over and over again......

Sora: It seems like I can do the kagura ritual dance from sunset to sunrise.

Sora: But I guess I should rest for now.

Sora: And return to the Rengoku Household.

He did just that in order to rest.

Senjuro: Ah, welcome back, Sora-san.

Sora: I've returned. It seems like Kyojuro already left for his mission.

Senjuro: Yes. He just left. Also, here. He told me to give this to you.

Senjuro hands what seems to be a letter and he was shocked to find out it was from Kagaya himself.

Sora: All right. I'll go take a break and read this letter.

He went to the veranda where he saw Shinjuro meditating.

S

hinjuro: Ah, Sora. Welcome back.

Shinjuro: Is your training done?

Sora: Yes.

Sora: Maybe I can do the ritual dance from sunset to sunrise.

Shinjuro: The Hinokami Kagura, to think that it was the Breath of the Sun.

Shinjuro: To think that there are two more users of the said the legendary breathing style.

Sora: You said before that it is where the other breathing styles branched from: Flame, Water, Wind, Stone, and Thunder.

Shinjuro: Yes.

Shinjuro: The previous flame hashiras kept records.....

Shinjuro: I accidentally tore those records.....

Sora: Oh......

Shinjuro: But as far as I know, there is also another clan who can perform the Breath of the Sun, and it is none other than the clan you descended from, Sora.

Sora: I know. I mean, the Uchiha Clan forgot the Hinokami Kagura.

Sora: Our family line is the only one who practiced the said kagura.

Shinjuro: So even within the Uchiha Clan, it even went extinct.

Shinjuro: Maybe Kamado-kun's and your survival......

Shinjuro: Is a miracle of some sorts.

Shinjuro: Maybe it is because you two are the chosen ones.......

Sora: No......

Sora: I don't really think I am one of the chosen ones.

Sora: Yeah, sure, I have these special eyes that were gifted by Amaterasu-sama.....

Sora: But the fact that Muzan still managed to destroy the village that was under my clan's protection.....

Shinjuro: The Uchiha Clan Downfall......

Shinjuro: That incident struck the Demon Slayer Corps as you already know the reason why.

Sora: Yeah.

Sora: That is my basis for that.....

Sora: It is because even with our abilities, we were never able to prevent the destruction of our village.

Sora: To the point that it my elder brother had to sacrifice his life just to protect me.

Shinjuro: ......

Sora: That is why, I will never forgive Muzan for what he did to my home, and to the people close to me.

Sora: That was probably the sole reason why I never forgot him even when I lost my memories.

Shinjuro: It must be rough.....

Shinjuro: Losing your home, your families, loved ones......

Shinjuro: Pair it up with nightmares.....

Shinjuro: I don't even know how are you still sane even after going all through that pain.

Sora: ........

Sora: But in truth, Shinjuro-dono......

Sora: I just wished that this pain will be over.

Sora: But I can't rest just yet......

Sora: Not until Tanjiro and I succeed in our goal, until we reach the end of our journey.

Sora: Turning Nezuko back into being a human........

Sora: Then, maybe......

Sora: I can join mother and nii-san.......

Sora lied with a smile on his face.

Sora: I'll just think about it when everything is over.

Sora: Anyways, I'll rest up for a bit. Then I'll head off once again.

Shinjuro: To where?

Sora: Oyakata-sama. He sent me a letter.

Shinjuro: Oyakata-sama? It seems like despite your reputation.......

Sora: !?

Sora: Wait, my reputation?

Shinjuro: Before Kyojuro even became the Flame Hashira, I was aware of the news of a certain criminal among the Demon Slayer Corps.

Shinjuro: The said criminal killed two civilians. As there are also two witnesses.

Sora: Could that be......?

Shinjuro: But, did this young man did it? This young man whose face is so gentle and kind?

Shinjuro: Even if I press him for answers, the fact that he lost his memories.....and the fact that he is on a journey to regain those memories.....

Shinjuro: Oyakata-sama didn't call a Hashira meeting and a trial for Sora, knowing that interrogating him......with him having amnesia.....

Shinjuro: Forcing him to remember is not really a pleasant method as it could damage him psychologically.

Shinjuro: On top of that, when he first visited here, he was sweating all over when he woke up, having a terrified expression on his face......

Shinjuro: And he told us that everytime he uses his Mangekyo Sharingan, he is plagued by nightmares whenever he loses consciousness or sleeps after he uses his ability.

Shinjuro: To think that I thought I was suffering way worse than other people when I lost Ruka......

Shinjuro: Seeing Sora's horrified expression, mumbling how he saw his family died over and over.......

Shinjuro: It is only a miracle he is still he still has his sanity........

Shinjuro: However, Kyojuro fears that Sora might not be able to hold it for so long, now that he is being hunted down for the crime that he did for the past seven years.

Shinjuro: However, Oyakata-sama seems to have a different angle to all of this.

Shinjuro: Knowing Oyakata-sama, he must've sensed something is wrong.

Shinjuro: If Oyakata-sama knows the truth, why isn't he saying anything? Maybe because he doesn't have enough proof?

Shinjuro: And the only one who can verify it is none other than Sora, whose memories are still a mess.......

Shinjuro: Takehiro.......

Shinjuro: If only I could help your youngest son......

Shinjuro: Physically, mentally, emotionally, and spiritually......

Shinjuro: This kid has been suffering too much.

Shinjuro: Lost memories, nightmares, branded as a criminal, even risking his life to fight off demons......

Shinjuro: Sora......

Shinjuro: I'd better write a letter to Kamado-kun and give him an advice to help him support his adoptive brother.

Sora left the Rengoku Residence and went to the Ubuyashiki Estate per Kagaya's request.

Amane was waiting for the Uchiha and they went inside the room. To Sora's surprise, he saw Kagaya lying on a futon.....and when he spots that his disease or rather curse has been spreading throughout his body as evident from his hands being rotten inside......

Sora could only pity and be worried for Kagaya.

Kagaya: Sora, you don't have to worry about me.

Sora: !?

Kagaya: Even though I can't see......I know the expression you're currently making.

Sora: Oyakata-sama........

Kagaya: Sora, your crow, reported back to me.....

Kagaya: I can only feel that it could lead you to uncover the truth when you awakened your Mangekyo Sharingan.

Kagaya: Although I fear that when you finally uncover the truth......

Kagaya: I fear that your mind wouldn't be able to handle it.....

Sora: I have prepared for this Oyakata-sama.

Sora: When I began unveiling my core memories......

Sora: I resolved myself that I'll face them, no matter what it takes....

Sora: Whatever sins that I've made in the past, then I'll happily accept the consequences of my sins.......

Sora: Even death if that would make things right.

Kagaya: Sora......you don't have to go that far......

Kagaya: Sacrificing yourself........

Kagaya: Think about the people who cares about you.......

Sora: Now that I'm being accused as a criminal.......

Sora: I really feel like I did something in the past and it hurts my heart when I think about it......

Sora: I-I......don't want the same thing to happen to Tanjiro and Nezuko.......

Sora: I.......

Sora: At this point I don't even know what to do anymore.......

Sora's eyes began to tear up......

Sora: Oyakata-sama, I don't even know if I can still continue on with this journey of mine......

Sora: I don't even know if I can still guarantee the safety of my two precious siblings if I learn the truth......

Sora: So......

Sora: Tell me......Oyakata-sama......please.....tell me......

Sora: What should I even go.....

Sora: To the left where nothing is right.......

Sora: Or to the right.....where nothing is left?

Silence fell on the room due to the weight of Sora's question. Even Amane, who is listening and at her husband's side......

Even she couldn't answer......

Kagaya and Amane knew the incident that involved the Kocho Sisters.

However, they only learned the side of the Kocho Sisters.

What about Sora's side of the story? Did he really killed the people whom he also cherished as his own parents out of cold blood?

Did he went insane?

Or was it something else?

So many questions yet few answers.......

Kagaya could think of many ways on how is he going to comfort the troubled heart and soul of the last Uchiha.

Kagaya: Sora........

Kagaya: You can't choose neither left or right.

Sora: What?

Kagaya: If you choose left......then everything you fought for......

Kagaya: The truth that is hidden within your memories......

Kagaya: They will never come into light and your soul would never be in peace.

Kagaya: However, if you continue to chose right, you're going to choose to sacrifice yourself, until nothing left......

Kagaya: I can't allow you to do either.......

Sora: Then........

Kagaya: Sora, move forward.

Sora: Forward.......?

Kagaya: Yes. Forward.

Kagaya: You are a good child......

Kagaya: And you don't deserve that painful suffering.

Kagaya: No one does, especially to someone like you.

Kagaya: I'm not asking you to run away from your past, I'm not also asking you to blame yourself either.....

Kagaya: Here is an advice.....

Kagaya: That maybe I can only offer to you.

Kagaya: Before that, let me remind you of something.

Kagaya: The Sharingan, are the eyes that reflects the heart. They are awakened when you experience extreme emotions such as sadness and hatred.

Kagaya: But they can also be righteousness and love.

Sora: Righteousness and love....?

Kagaya: Do you know how Sasuke even awakened his Sharingan?

Sora: No......even though I read his journal.

Kagaya: He awakened the Sharingan, out of the desire to protect you, his precious little brother.

Sora: ........!!!

Sora: To protect me.......?

Kagaya: Yes. The desire to protect you, born out of love.

Kagaya: And you, Sora, awakened yours after witnessing the death of your brother, right?

Sora: No, I thought that I awakened my Sharingan when I saw my brother died but.....

Sora: When I got to focus, when I carefully recalled the events that happened.....

Sora: My Sharingan was awakened, when my brother and I.....found our mother's lifeless body......

Sora: She was killed by a demon.....

Sora: And the fact that I knew about our mother's condition when I thoroughly read my brother's journal.......

Sora: My Sharingan was awakened out......of sadness......

Kagaya: Out of love for your mother.

Sora: I just lost not only my mother on that day, but my brother as well.

Sora: I think nii-san wants to tell me about my mother's condition but I guess.......

Kagaya: Sora........

Sora: But as for the awakening of my Mangekyo Sharingan.....

Sora: .........

Kagaya: I think I know how you awakened it. But it is only just an hypothesis of mine......

Sora: What could it be.....?

Kagaya: It must be.....the "sin" that you chose to carry upon yourself.

Sora: I see.......

Kagaya: But, Sora, whatever you find.....in your next mission......

Kagaya: Please, come back safe, so that if you finally remembered what caused you to awaken your Mangekyo Sharingan.......

Kagaya: Then I may be able to find a way to clear your name.

Sora: Thank you, Oyakata-sama.

Kagaya: Now then, on your next mission.

Kagaya: The Sound Hashira, Uzui Tengen, along with Tanjiro, Zenitsu, and Inosuke, they went and infiltrated the Yoshiwara District.

Kagaya: I want you to help them.

Sora: Another, Hashira? Oyakata-sama, with all due respect but.....

Sora: I'd rather work secretly, this time.

Sora: I'd only notify Tanjiro.

Sora: With what happened to the Butterfly Estate....

Sora: I fear that Zenitsu and Inosuke are having doubts about me.

Kagaya: Sora, do not worry. Tanjiro and his friends.....

Kagaya: They believe in you.

Sora: In me......?

Kagaya: You proved it through your actions.

Kagaya: So, there is no need to doubt yourself.

Kagaya: Especially Tanjiro, whom you genuinely thought of you as a real brother.

Sora: .......

Sora: *sob*

Sora's heart somehow found relief....not only due to Kagaya's soothing voice but his reassurance that there are still people who believes in him, like Tanjiro, Zenitsu, Inosuke, Kyojuro, Amane, and Kagaya.

Sora: I will do my best.

Sora: I promise......once this mission is over......

Sora: If I ever gained a fragment of my past......

Sora: Then.......

Sora: Please, Oyakata-sama, would you allow me, to come back here, with Tanjiro and Nezuko?

Kagaya: Of course.

Sora: Thank you, very much.

Sora then finally left for his mission.

Kagaya and Amane were alone in the room as Amane asked

Amane: Kagaya, do you have an idea on how Sora managed to awaken his Mangkyo Sharingan?

Kagaya: Looking back on that incident seven years ago......

Kagaya: Knowing Sora's personality....

Kagaya: The Kocho Sister's side of the story.....

Kagaya: It is only Sora's side that we don't know.

Kagaya: But my speculation is.....

Kagaya: Since Sora......is being hunted down by Muzan......

Kagaya: Muzan planned.....

Kagaya: To torture Sora.....

Kagaya: And that involved the parents of the Kocho Sisters.....

Amane: !?

Amane: Kagaya, are you saying—

Kagaya: It is the only conclusion that I can draw from.

Kagaya: Sora's previous crow, Kazuki, he kept quiet about the incident as he said it is part of his master's wishes before he deserted the Corps.

Kagaya: ..........

Kagaya: Sora.......

Kagaya: I don't know what horrors you've faced but.......

Kagaya: If only you've been open from the start......

Kagaya: Then I could've even helped you even better.

Kagaya: Anyways, Amane, about the report that Shinobu and Kanae sent to us......

Amane: Yes. They confirmed Uchiha Madara's existence and location.

Amane: Not to mention is hiding place.

Amane: As for the crows, it was also Madara's doing.

Kagaya: .........

Kagaya: What does he plan to do?

Amane: I don't know but.....

Amane: Kanae and Shinobu said that once the swordsman finally comes back to him......

Amane: Once he gets hold of the Kotoamatsukami.......

Amane: He will finally exact his revenge upon the Demon Slayer Corps and upon Muzan......

Kagaya: Kotoamatsukami........

Kagaya: Could that be........

Kagaya: Sora's Amatsumikaboshi.......

Kagaya: Amatsumikaboshi, named after the god of the stars that is said to exist before......

Kagaya: The Kotoamatsukami.......

Amane: *gasp*

Kagaya: Could that be......

Kagaya: Amane......

Kagaya: It seems like everything is about to fall into place....

Kagaya: Uchiha Madara.......you may have been able to make a great contribution to our cause.....

Kagaya: But I won't allow you get to Sora.......

Kagaya: Muzan......

Kagaya: I won't also allow you to kill Sora.......

Kagaya: Amane.....

Kagaya: It's safe, isn't it?

Amane: Safe?

Kagaya: Sasuke's eyes.

Amane: !?

Kagaya: We have a lot of work to do.

Kagaya: Freeing Sora of his misery.....

Kagaya: Clearing his name.....

Kagaya: Learning about this Kotoamatsukami......

Kagaya: Preventing it from falling it into the wrong hands.......

Kagaya: Uncover the truth behind the awakening of Sora's Mangekyo Sharingan....

Kagaya: To reconcile a bond that was shattered by hatred and sadness......

Kagaya: Sasuke, just as I promised. I will do EVERYTHING to help your brother. I swear, I won't let myself die before I even fulfill that promise.

Meanwhile as for Sora, he made his way to the Yoshiwara District and when he arrived......

It was still around noon.

Sora: I'd better find Tanjiro real quick and ask him about their mission.

Will he be able to see through the blinding lights of a district dazzling in hatred and love?

Or will his eyes give out before he is able to perceive the truth that an Upper Rank Demon continues to devour the people within this district.
