Can I make it alive? (Kny x reader)

The start before the Mugen Train arc

(y/n) p.o.v

After a few weeks of Tanjiro's training, we are now in a room with Tanjiro and Inosuke's sword maker. We now watch Inosuke outside picking up a stone from the ground. When he found a stone he liked he hit it with his newly made sword which caused Kanamori to lose his temper while Tanjiro apologized again and again and I was on the sideline holding back my laughter. After that incident we are outside the Butterfly estate saying goodbye to Haganezuka who is leaving and Kanamori who is now still mad at Inosuke.

As we are now walking back to the Butterfly estate. I was wondering why  Haganezuka was acting strange earlier. He is very quiet unlike the show I watched him. He should be poking Tanjiro's cheek or pulling his hair or even hitting him. But he didn't, he sit there infront of me not doing anything. I brush it off of my mind and focused my attention on walking.

TIMESKIP~~

We are now happy for Tanjiro when he finally able to defeat Kanao. I laugh softly when the three girls and Tanjiro jump happily. I congratulate Tanjiro to his achievement making him look at me and smile proudly. While the two looked at Tanjiro and started to training too. I cheered the two making them to motivate and train as hard as they can like Tanjiro did.

TIMESKIP~~

I'm here now at Oyakata's estate. I asked to talk to him before our next mission where Kyojuro would die. "Before we even start. I want to thank you again, because of you my sight returned and I can see their appearance and nature. What exactly is the reason why you want to talk to me Kamado (y/n)?" What he told me. "I'm here today to say that I had a vision about Kyojuro." I said and looked at him. 'I couldn't tell him that I came from another universe.' "What is it? Tell me." There was concern in his voice

"Kyojuro will die at the hands of the upper 3 demons. But don't worry because I will do everything to make sure he doesn't die. That's all I want to tell you, Oyakata-sama." I said. "Thank you so much for telling me this. I have faith in you and your siblings, and also you three is one of my hopes to defeat Kibutsuji Muzan." I smiled at him with mixed hope and determination in my eyes that Tanjiro will be able to defeat Muzan.

After our conversation, I returned to the Butterfly estate and rested for our next mission. I am laying down with Nezuko in my side and started to close my eyes.

Next day. I'm with Tanjiro now to see and to talk to Aoi and Kanao. We met Genya on the way where Aoi and Kanao. Tanjiro's shoulder collided with his body which was bigger than him. 'Grabe mas malaki pa pala ang katawan niya sa personal.' (His body is much bigger in person.) After we talked to Aoi and Kanao and after the three of them destroyed the large gourd. We are now outside the Butterfly estate telling them good
bye to go to our mission.

TIMESKIP~~

We are now standing in front of the train while Inosuke is shouting in front of us because of the size of this train. "Hey! This... What kind of creature is this?!" He shouted and pointed to the train in front of him. "This is right? The ruler of the land." Inosuke said, and ran to the other side of the train. "This length and this feeling of oppression. I'm definitely right." He said still looking at the train infront of him. "It's a train Inosuke-kun." I said holding my laugh because of his antics.

He put his index finger to my lips. "Keep quite! I attack first. Stay behind I will protect you Minion!" I laugh softly to what he said and Tanjiro spoke too stopping Inosuke to attack the he so called The ruler of the Land. "Hang on, Inosuke! Think about it. Maybe it's a guardian of this land. It's not appropriate to suddenly attack it." Tanjiro said making me laugh even more while Zenitsu looking at them like they're a crazy. "(y/n) already said it, it's a train. Do you understand? A transportation vehicle. It's for carrying people. You bumpkin" Zenitsu said. While Inosuke walking away to the train and stopped for a little bit, we watch him and suddenly he run towards the train and headbutting it. Zenitsu scream at him.

The Police officer run over us. "What are you guys doing? They are carrying swords." Because of that we run away and hide. Zenitsu explain to the two why the police didn't like them carrying a sword and suggest to hide their swords. Inosuke laugh and stood up while his sword is in his back making me laugh again. When the train is now leaving Inosuke jump and chased the train. Tanjiro carried me and run too. When we make it there Tanjiro and Inosuke help Zenitsu to climb in the train.

"It's so fast." Inosuke said while feeling the wind. I agreed to him feeling the wind as well. When we me and Inosuke are busy to whatever we are doing.

3rd p.o.v

Zenitsu and Tanjiro are talking behind the two. "Tanjiro. Is it okay to bring (y/n) and Nezuko along? Keeping them at the headquarters of Demon slayer corps should be that safest option." Tanjiro smile at his concern. "It's fine. No matter where we are Nezuko, (y/n) and I will always be together. I'll never part ways with them again." (y/n) look behind her and smile over Tanjiro and point the things she see and laugh because of Inosuke's antics making Tanjiro smile at her softly and look the box behind him. 'We will be together. I will protect them in all my might, because they're my precious younger sisters. I will never make a mistake again for leaving them. I promise, I will protect you two!' Tanjiro's mind while looking in the dark sky with a determination in his eyes.
