My sword be belong to my uncle _____???

(The next day)

Sabito pov:

I put Yn's box on my back saying goodbye to Hisa. I walk in the woods heading back to the home. "I still can't get out that dream I had last night". I stop walking looking up at sky. "Why did I dream of something like that we are dating but doing stuff like that to her I don't th-". I was cut off by someone calling out to me. I turn my head and Tanjiro and his friends running up to me. "Sabito so glad we find your friends was really worried about you and Yn when don't return to the headquarters. I told them that I got injured and we stayed in the safe house for the next. "Hold on your the guy who is the strongest out all of them". Inosuke said pointing his sword at me. "YOUR THE STRONGER OUT OF ALL THE HARHIRA HOW". Zenitsu yelled at me. Something I wish he stop doing that. "That because in the final selection sabito almost killed EVERY demon but one he the reason why most kids became demon slayer. We all look at the box on my back hearing Yn talking about me killing almost all of the demon. "What you say sabito killing almost all the demon but one why"? I put the box down under a tree so yn can come out and tell them what happened. "Sabito grab me our friends and hide behind a tree telling me he back but thing is since Sabito was killing those demon he got to excited and forgot to concentrate on his breathing and when he try to cut the demon neck his sword broke". I look at yn seeing her ears fall back. "So what happened next". Tanjiro ask yn. "I saw the hand of the demon racing to sabito's head I run and jump up to grab sabito and cut the hand I don't know what happened next but last thing I saw was purple lightning coming down at the demon and that's why my sword looks like this". Yn put out her sword to show the three kids.

(Just in case you forgot what your sword looks like)

"What I seen that sword before in my dream". Tanjiro said getting closer to it. Everyone look at him waiting for him to say something else. "Yeah I have and someone was holding saying that this sword is nothing a normal sword but the first sword that every been made". We all look at Tanjilro shock at what he said. "You know what you guys are the first one to see my sword". Yn said smiling down at her sword. "Come out sabito let head back so we know more about me sword". I smile at her and nodding watching her get in her box. I put the box my back and bye to the kids.

(Back at the headquarters)

I open the door and see everyone. I turn my head and see Makomo and Giyuu speed walking to me. "Sabito Yn am so glad you guys ok what"? Makomo ask me hugging me. I told them what happened and that Tanjiro told me and yn about her sword. "What about her we know that it different than everyone else sword". I told them that Tanjiro said he saw someone hold the same sword as Yn and need to find out what so special about it. "Well good cuz Kagaya will be here soon". Giyuu said turning to everyone. We walk up to them and I put the box down on the porch when Kagaya will be standing soon.

(Almost end of the missing)

Yn pov:

I look up at Kagaya who getting ready to leave. "Kagaya please wait I have something important to talk about to everyone it about my second". I pull out my sword and everyone eyes widened. "It's that" "it can't be right". I turn to everyone seeing them shaking. "HOW CAN SHE HAVE YORIICHI SWORD THAT IMPOSSIBLE" Uzui yelled. "Yn have a sword like Yoriichi that is important". Kagaya said walking with his kids helps. "What who Yoriichi another hashira we don't know". Makomo ask everyone. "Oh Yoriichi is my uncle he's the most powerful swordsman every and born with demon slayer mark like me". I lift up my hashira out shirt and show them my mark going down my stomach.

(Like this)

"YORIICHI IS YOUR UCLA"!!!!

Still Yn pov:

I jump by everyone yelling at me. "Yeah sorry I tell you guys about that". I rub the back of my head. "Not only your the daughter of Muzan but also the niece of Yoriichi but how". Shinobi ask me. "Well Yoriichi and my mom our siblings and my dad Muzan didn't know who my uncle was at time and when he finds out about my dad try to keep me and my mom away from him but I don't know why". I look down at my sword and smile. "But all I know it that my uncle want me to stop Muzan".
