Uchū's POV:
Ginga, Yuni and me were just in our bedroom when all of a sudden a portal showed up and sucked us all in. Me and yuni were now in a forest I couldn't see ginga anywhere so we must have been splited by the portal "where are we?" Yuni asked, she just woke up "I don't know.. a portal showed up and sucked us in" I replied "where's ginga?" She says, while looking around "the portal must have splited us, so ginga must be here somewhere" I said while looking around. About a minute later a piece of paper was now in my hands, I looked at it and I recognized the hand writing. It was a letter from ginga "hey, yuni! Ginga wrote us a letter!" I said shouting in front of me, yuni turned around and speed-walked to me. When she was now close to me I read the letter out loud
'Uchū, Yuni I know where we have been sucked into. We are in demon slayer right now, I'm guessing you must be in a forest by now? Well right now I'm in the infinity fortress. Yuni you must transform into your cat form and don't let anyone know about you being a neko, since they might think your a demon and try to kill you. I know were immortals but still just keep your neko identity a secret'
No one's POV:
as uchū finishes reading the letter out loud, yuni immidetely turns herself into a cat, while uchū is creating herself a nichirin sword and a demon slayer uniform, she also created herself a white haori with long sleeves, she made herself different colored socks and different colored sandals just by using her power "what do you think my breathing style should be?" She says as she puts her sword in her hip, "maybe something you like doing on your daily life I guess?" Yuni says her voice really low but loud enough for uchū to hear "ah! I know how about song breathing?" Uchū exclaims "that's ok I guess, you do you" Yuni replied sounding tired "c'mon yuni get on my shoulder!" Uchū says, yuni does as what she is told and gets up on uchū's shoulder, 'I should think of how many song breathing forms I should make... Maybe 37 forms is ok? Yeah I think that's ok' uchū says in her head while she runs to a mountain she is familiar with. Once she's in the mountain yuni got of her shoulder and went somewhere else, while uchū goes straight getting her sword out and ready to what seems like defend,
-CLANG!-
uchū has hit another persons sword, the person landed in front of uchū. The person turned around and said "ara~ ara~ a kid? What are you doing here in mount natagumo?" She said, uchū didn't say anything "w-who are you?" Someone said behind uchū, she turned around and saw Giyuu the water hashira, tanjiro and nezuko kamado "I'm Uchū nice to meet you three" Uchū says blankly, she then turned around to shinobu "you know kid, you do know you are defending a demon right?" Shinobu said "I know, so what about it?" Uchū said "your not supposed to defend a demon! Your supposed to kill a demon That's what demon slayers are for!" Shinobu exclaims "oh, shut up you mosquito" Uchū says sounding annoyed, shinobu had clear irk marks on her face meaning she was now angry "you know that it is not nice to call a hashira like that" shinobu says trying to hide her anger with a smile on her face, clearly failing "so what if your a hashira? Does it look like I care?" Uchū says, sounding irritated "ara~ ara~ you are a really-" shinobu was about to say something but she was cut off by a crow saying "CAW CAW CAW CAW! BRING TANJIRO CAWMADO AND HIS DEMON SISTER BACK TO HQ! CAW CAW CAW CAW BRING THE KID TOO!!" the crow said loudly enough for all of us to hear "ara~ ara~ your lucky I can't fight you kid" shinobu said "whatever" I said sounding a bit more annoyed, then yuni appeared and hopped on uchū's shoulder "you have a cat?" Tanjiro says behind uchū, uchū turns around and says "yeah I do" with a smile "we better get going, master wants you and your sister in hq you too kid" giyuu said while looking at me and tanjiro "hai, tomioka-san!" Tanjiro exclaims
In The Demon Slayer HQ
Uchū's POV:
All the hashiras were here and they were all looking at tanjiro and the box and then me, suddenly sanemi grabs tanjiro's box while obanai pins tanjiro on the ground, his face hitting the ground. Sanemi pulls out his sword and begins to stab the box this made me fill with rage, yuni got off my shoulder knowing what I would do, I then begin to run to sanemi. Sanemi must have thought I was going to punch him but he thought wrong, I slid down and attacked his legs, he tripped and lost his grip on the box I immidetealy grabbed the box, and pulled out sanemi's sword throwing it far away from him, I then began to walk to obanai's tree and placed the box there, sanemi got up and shouted "WHO THE HELL DO YOU THINK YOU ARE KID?! ATTACKING A HASHIRA LIKE THAT?!" he yelled at me, I turned around and gave him a middle finger and said "well if you didn't stab nezuko out of no where I wouldn't have been mad" "WHY YOU LITTLE-" sanemi was about to say something but he was cut off by the ubuyashiki twins saying "the master has arrived" sanemi quickly turned around and bowed down, everyone did the same except for me 'I know were all supposed to bow down to the master but, it's kind of embarrassing for me...' I thought to myself, kagaya ubuyashiki was now in front of a the hashiras "hello my children, I'm guessing you know why your all here?" "Yes master" says sanemi
I'm lazy so i'll just say sanemi did whatever he did in the anime
Still Uchū's POV:
"Well now we know that nezuko kamado will not harm anyone" sanemi just made a 'tch' noise and got back to where he was, while nezuko was in her box in the shade "I almost forgot that there was also a child here.. child may you tell us your name?" Everyone looked at me except for master since he's blind "my name is Uchū" I said "I can also hear a cat, do you have a pet Uchū?" "Yes, yes I do" I said "what is their name?" He asked "yuni" I answered "well, now that we know who you are you don't mind being in the butterfly mansion do you?" Master said, I went silent I clearly did not want to live in shinobu's estate, everyone could tell that I had irk marks on my face even tho I looked calm "no I don't mind" I said trying not sound irritated, but failed "well.. if you don't want to stay in shinobu's estate then how about someone else's?" Master said, he seemed to know that I didn't like shinobu one bit "you can choose which hashira you want to stay with" master said 'I don't know which one to choose... I'll let yuni choose' I thought to myself, yuni got on my shoulder and I began to whisper something in her ear while the hashira's just looked at me confused, yuni then got off of my shoulder and began to walk to the hashiras and sniff them, the hashira's were all confused, yuni then got on my shoulder and whispered something to me "gyomei, is the best choice he knows how to take care of children, sanemi is aggressive so no, mitsuri has bees and I don't want to get stung by them nor do I want you to be stung, obanai would also be a no since he hates giyuu, giyuu's estate is far away, uzui's has bright gems or stone in his estate so also a no, rengoku's dad is drunk so it's also a no, and we already don't like shinobu" yuni whispered in my ear "have you made your decision yet my child?" Master said "yes, I have" I replied "well, then who is you wish to stay?" Master asked "the stone hashira gyomei himejima" I replied "may I ask why gyomei?" Master asked again "sanemi is aggressive so no, mitsuri has bees in her estate which me and yuni are afraid that one of them might sting us, obanai is also a no, tomioka's estate is far away, uzui has gems on his house, rengoku... Rengoku is a no because of his father" everyone looked at me surprised "how do you know all that?" Mitsuri asked with a surprised expression "yuni told me" I replied "yuni? Your cat can talk?" Obanai asked "no, but I'm the only one who can understand her" I lied "well, then know that you have chosen who to stay with, kamado tanjiro and his sister kamado nezuko will be staying in shinobu's estate" just then the kakushi came and picked up tanjiro and nezuko, and started to carry them to shinobu's estate "uchū I have almost forgotten to ask you your age, how old are you?" Master asked "I'm 12" I replied, everyone went silent and looked at me. Sanemi then broke the silence by shouting "YOUR 12?! I THOUGHT YOU WERE THE SAME AGE AS MUICHIRO SINCE YOUR ALMOST THE SAME HEIGHT AS HIM!!" Sanemi yelled in disbelief everyone was also surprised to hear that I was actually 12 "I always thought that muichiro would be the youngest demon slayer! But I was wrong!" Rengoku exclaimed "if your 12 how come you and muichiro are like the exact same height?" Obanai questioned "I just sleep a lot" I answered "well then, my children you are all dismissed" master said and they all went to wherever they're going, gyomei walked to me and said "follow me uchū" "hai" I responded he then began to lead the way to his estate
In Gyomei's Estate
Yuni and me were now in himejima-san's estate, he showed me where the guest room was and also showed me around his house, it's a surprise that he knows his way around the house when he's blind. I was just in my room reading a book I found on a desk, when himejima-san knocked on the door "what is it himejima-san?" "do you want to train?" He asked "sure" I replied, I opened the door to see him in front of me, he then lead me to where he trains "first thing for you to do is to stay underneath the waterfall and chant, then you need to carry three logs on your shoulder and then you need to move a boulder through a town. But since you are a child I got you a smaller boulder and smaller logs" he said "hai, himejima-san" I replied and went to the waterfall and began chanting, after about an hour of staying underneath the waterfall still chanting, himejima-san let me take a 10 minute break for a while and then he let me move to the second training which is carrying three logs on my shoulder. After two hours of carrying logs to wherever he wanted me to place them I was then given a longer break which is 20 minutes. After the break I then went to the boulder that was the same height as me and began pushing it through town, three hours later I was now back with the boulder, I was sweating only a little bit himejima-san was impressed and he smiled and patted my head, I smiled back at him. We then went back to his estate to eat dinner
