*knock knock*
Y/n: can one not mourn in peace for fuck sake. What?!
The door opens revealing Tanjiro.
Tanjiro: Hello Y/n-San, uh um. I'm sorry for your loss.
Y/n: spit it out kid. I don't have time to chit chat.
Tanjiro: well uh. Rengoku-San wanted me to give you a message when he passed.
Y/n:...
Tanjiro: uh... He asked that you take care of yourseld and wanted you to remember his mother's words before you left to your hometown.
Y/n:... Get...out.
Tanjiri: yes, sir!
...
I'm gonna switch up the time line a little. Haganezuka will confront Tanjiro before his trip to the Rengoku residence.
Tanjiro was taking a walk to clear his mind. He was told to stay in bed but he had to clear his mind from the events.
Tanjiro (thoughts): do I have a fever? I can't breathe.
He heard a sound and looked up to see his sword maker, Haganezuka. He was holding two knives and two knifes held up by his headband like horns. He had a terrifying aura surrounding him.
Tanjiro: huh? Haganezuka-San!
Hagenezuka screams and scolds tanjiro.
Hagenezuka: you lost your sword? Are you out of your mind, you fool? You deserve to die ten thousand times over!
He began to chase Tanjiro with surprisingly lightning-quick speed. Tanjiro running away and apologizing hoping the maniac behind him would stop and reason.
Tanjiro: I'm sorry! I'm sorry! Please! I'm truly sorry!
They chased each other for hours before Tanjiro decided to climb a tree. Hagenezuka climbed the tree as well using his knives as tools to climb the tree. Tanjiro screamed and switched to the next tree to slide down it, meanwhile the crazy Hagenezuka decided to jump down the tree. Quickly following Tanjiro.
???: Hey you! Stop it!
Hagenezuka: huh? Who are you?!
The Mysterious man head was being covered by the conical hat he was wearing.
Y/n: I'm a Hashira. Stop chasing my tsugoku. So what if he lost his sword? Stop being a loser and get working on a new one or I'll stuff those knives up your ass so you lose them.
Haganezuka quickly ran back to the swordsmith village. Tanjiro was trying to catch his breath. It was daybreak by the time Y/n came and saved him.
Tanjiro: thank you, Y/n-San!
Y/n: I didn't save you because you were in trouble. Now, I got nezuko here, let's go. I did it because of necessity.
Tanjiro: where are we going? I can carry Nezuko, Y/n-San. I don't want to trou-
Y/n: Nonsense, you're injured. Don't be stupid. We're going to the Rengoku residence. I was told you needed to go there to deliver another message. I also wanted to go there.
The air felt thick as Tanjiro felt awkward about their last interaction.
Y/n: I also wanted to thank you for giving me that message. I know I was rude after you gave it to me. But I wanted to be left alone after that.
Tanjiro: It's alright, Y/n-San. I understand.
...
Y/n: come on kid. Just a little bit further. You know what I'll just carry you.
