-----------------------------------------

When everyone woke up Drake started to look around deciding who to choose.

Drake: Ok let's go with- *eyes widen* OH SHIT OH FUCK OH SHIT OH FUCK.

Y/N: Drake what's wrong?

Drake: ONE OF THE WORLDS IS ABOUT TO BE FUCKED UP.

Y/N: Which one?

Drake: DEMON SLAYER. FUCK IT. IM SENDING YOU THERE, GO AND HELP GIYUU OR THE WORLD IS DONE FOR. *creates a portal* YOU'LL GET ALL THE INFORMATION INTO YOUR HEAD AS YOU GO THROUGH. I'LL GIVE YOU SOMETHING THAT WILL HELP YOU. NOW GO GO GO

Y/N quickly stood up from his seat and ran through the portal as it closed.

Drake: *calms down* *sigh* I hope he will be able to do it.

Ayaka: Excuse me. Why were you panicking so hard?

Drake: *sigh* You see in that world, or at least in the AU of that world Giyuu snaps at Shinobu and kills her because of her insults. And in the fit of rage he kills 3 hashiras along with Shinobu. After he flees and meets Muzan and
becomes a demon and then the world is doomed.

Summer: That's horrible. Can we watch him?

Drake: Sorry but no. Because the orb didn't send him we can't. If it was happening in the theater we could but it's different universe we're talking about and without a strong signal support from the orb we can't. While he's saving the world how about you play some games and I go and make sure he's alright. 'Plus I need to inform an old friend about Y/N'

-With Y/N    3D POV(after he walked through the portal and got the information)-

Y/N: *falling from the sky* WHY DIDN'T HE TELL ME THAT THE PORTAL WAS IN THE AIR!? WAIT, I'M A DUMBASS.  KAISEL

As he said that a dragon appeared beneath him catching him before he hits the ground.

Drake: Thank you Kaisel. Now where is the Hashira meeting place? How is it called again? Ah fuck it. Kaisel if you see a Butterfly estate from here fly there.

Kaisel looked around for a moment before he started to fly to the south. After a minute Y/N could see a Butterfly estate as well as the Hashira meeting place. As he was above it he dismissed Kaisel and started to fall.

-Meanwhile on the ground-

Kagaya: Thank you for coming everyone. Today I have important news. Also I was told that you have a message for me.

Giyuu: Yes. May I speak Ubuyashiki-sama?

Kagaya: You may Giyuu.

Giyuu: I want to inform you that I met a boy that travels with his sister who got turned into a demon. But I also wanted to tell you that when I tried to kill the girl and knocked the boy out she instead of eating him, protected him and fought me.

Kagaya: Interesting, thank you Giyuu.

As the meeting continued Shinobu started once again annoying and insulting Giyuu. While this was happening Giyuu just ignored her and listened to Kagaya.

Giyuu: 'What is this warm feeling? It's like someone is comforting me with a hug'

He dismissed this thought and continued to listen but little did he know that the warm he felt was indeed a hug, a hug from a spirit of Kanae hugging him.

Kanae: I know you can't hear me but please stay strong Giyuu.

As Kagaya was speaking one of his daughter interrupted him.

Kanata: Father there is a large shadow above us. *the shadow dissappears* It disappeared.

Kagaya: Ah, seems like he's here.

Mitsuri: Who Ubuyashiki-sama?

Kagaya: A man who will help us. An old friend of mine sent him.

As he said that something or rather someone landed behind the hashiras, making a huge dust cloud, while they stood up and readied their swords to fight. As the dust cloud disappeared they saw a man standing there.

Y/N: Ok I'm here. *notices the tension* Oh hello everyone.

Sanemi: Who are you?

Kagaya: Are you Y/N?

Y/N: Yes. How do you know me?

Kagaya: Drake informed me that you'll be coming to help. Children please calm down he's not a threat plus I doubt you could even harm him.

Obanai: But Ubuyashiki-sama-

Kagaya: Calm down.

After everyone calmed down, they were now sitting down in front of Kagaya while Y/N sat next to him.

Kagaya: So Y/N, what is the other problem that may hurt us greatly beside Kibutsuji?

Y/N: It'll be a big surprise to all of you but it's Tomioka Giyuu. And that's because- *notices what Shinobu is doing* One second. Ahem. *she still doesn't pay attention* AHEM *she's still at it* *notices that Giyuu is about to snap* Sorry for this Kagaya.

Kagaya: It's ok.

Y/N: SHINOBU WOULD YOU PLEASE STOP BULLYING POOR GIYUU AND FUCKING LISTEN.

Everyone flinched when he screamed and because of his tone, except Kagaya because he already knows what Y/N can do and Muichiro who was looking at the clouds as always.

Shinobu: Y-yes?

Y/N: Stop. Just fucking stop. Does it give you joy in bullying Giyuu?

Shinobu stays quiet.

Y/N: That's what I thought.

You looked at Giyuu with the "I'm sorry" look and he gave you a small smile that said "it's ok, you can" so Y/N continued to speak.

Y/N: Do you think his life was easy? No, he had a harder life that any of you. He lost his sister to a demon. Then after he thought that he finally found a new family they got killed by a demon as well. That was the last straw and he almost lost his emotions. He still has them but he doesn't show them.

As he finished talking everyone had sad faces with wide eyes and some were crying. But he wasn't finished.

Y/N: And finally he lost the only person who he loved.

Y/N walks over to Giyuu, kneels in front of him and looks to the right.

Y/N: Isn't that right..........Kanae.

Everyone was once again shocked at his statement while Kanae on the other hand looked at him and hoped that he could hear her as well.

Kanae: *with tears* Can you hear me?

Y/N: I can Kanae.

Kanae: Could you please tell my words to them.

Y/N: Why don't you do it yourself?

Kanae: But I'm dead.

Y/N: *stands up and turns to Kagaya* Kagaya can I have your permission to visit her grave.

Kagaya: Of course.

Y/N: Thank you. I ask everyone as well as you Kagaya to come with me. *everyone nodded and he turned to Kanae* Please lead the way.

She nodded and started leading him to her grave while the others followed. After a few minutes of walking they arrived at her grave. Y/N walked up to it and stood in front of it.

Y/N: Before I do it, Kanata please give this potion to your father. *gives her a potion*

She walks back to her father and gives him it. As he drank it all his curse started to dissappear and he could see again. To say that everyone were in shock would be an understatement.

Kagaya: *tears up* I-i can see. I can see!

Y/N: You're welcome. Now *looks at the grave and says one simple word* Arise.

As he said that the shadow started to come out from the ground and started to take form. After it stopped everyone once again had shocked faces, right there in front of them stood Kanae. (The same thing as Sung Jin-Woo did in the manga)

Kanae: It's good to see you all again.

Y/N: I'll leave you, tell me when you're finished.

With that he walked away and stopped in front of the lake. A minute later Kagaya stood next to him.

Kagaya: I wanted to thank you not only for healing my curse but for letting us to talk to a comrade, friend and a lover.

Y/N: Really? *chuckle* Lover? Well I suppose you could say that. It's so obvious that she and Giyuu have hots for each other.

Kagaya: Indeed, when will you be leaving?

Y/N: Drake will open a portal for me after I dismiss Kanae back into afterlife.

Kagaya: Yes, we wouldn't want dead people to just walk around.

Y/N: *chuckle* True. I'll give you a tip. When you meet a kid named Tanjiro train him in everything you can. He's the key to defeating Kibutsuji as he's the successor of the Breathing of the Sun.

Kagaya: Thank you for this information. It'll help us greatly. Let's go back now. I think everyone is done.

Y/N simply nodded and they started to walk back. When they arrived Y/N was met with a hug from Giyuu as he was saying thank you over and over again with tears. Y/N hugged back and whispered to him.

Y/N: *whisper* You are not alone. Everyone including them are watching over you.

He nodded and broke the hug. Y/N walked in front of Kanae and she nodded.

Kanae: Bye everyone.

Y/N: Cancel summon.

With that she disappeared and Y/N turned to the others.

Y/N: I'm glad that I could help but my time here is up. *a portal opens next to him* Seems like it's a good bye. Oh and Sanemi stop being a bitch and spend some time with your brother or the next time I'll come here will be with a purpose to beat you up.

With that he walked through the portal as it closed.

A/N: Hope you enjoyed. I got this idea while I was listening to Demon Slayer OST. Have a good day/night. AUTHOR OUT
