The Unknown Hashira (Demon Slayer x Reader)

[11: First breathing]

Tanjiro just finished training and now he's resting with his other friends, when he realized something. He turned to one of the kakushis and asked. "Uhm, I just wanna ask if Y/n-san is here?" The kakushi nodded and told him to go up to their room. The boy thanked the kakushi and then went up to Y/n. 

Earlier on, he remembered his last memories with Rengoku, the man said that maybe his family could help him find out what Hinokami Kagura is. Also, since Y/n told him that he should use Hinokami Kagura as his breathing means that there is more to it, so he needs to ask the hashira. 

When he got there he smelled the intoxicating scent of the hashira, meaning that the hashira is not covering their body, that's what the kakushis said to him. He decided to knock on the door and make his presence known so the hashira could get ready. He heard a jumble of words in the room and a bunch of ruffling. After a few seconds, the door opened and revealed the hashira drinking some tea. 

"Well, good afternoon, young boy. What brings you here?" Y/n asked and Tanjiro sat down when the hashira offered a seat. "Are you done with your training session?" The hashira asked. 

"Yes, we're done with the training. But I want to ask you something." The hashira hummed, telling him that they are listening. "Before Rengoku-san died, he told me that I should go to the Rengoku residence and ask for the notes of the preceding Flame Hashiras, he told me that there might be records of Hinokami Kagura there," Tanjiro explained, Y/n nodded. 

"So I came here to ask if you know where the Rengoku residence is," Tanjiro asked, looking down not wanting to remember the rest of the memories. "If you don't know the residence, it's fine-" 

"Well, you're in luck, young boy! I knew their house since I've been there!" Y/n said eccentrically, making Tanjiro shocked. "I'll give you the address, but can I come with you?" The hashira asked. 

"Huh? Uh, you don't need to Y/n-san, you can just stay here and I'll go tomorrow morning!" Tanjiro said as he violently wave his hands in the air. "Plus, I'll just ask if they can let me borrow the notes, I'm sure nothing bad will happen," Tanjiro said, Y/n hummed. 

"Fine, if you insist, young boy. But I must tell you that not all of them will be like Kyojuro, okay?" Tanjiro was confused about that. "Well, young boy. You can go now and rest, you have a long day tomorrow."

Lunch just finished and Tanjiro got ready to go and travel towards the Rengoku residence. Y/n saw this and saw him saying his goodbyes to his friends, Y/n thought of something about how to follow the boy without him noticing. 

"How can I follow him? He seems to smell a lot of things so I can't just shapeshift mindlessly. Maybe an animal could do." Y/n murmured, looking around to see what animal they could transform into, then they noticed the crow. "Oh, yes. This is the animal that I need." 

Y/n thought of the crow and started transforming, getting smaller and smaller until they reached the same size. "I just gotta fly way higher than them so they wouldn't notice me," Y/n murmured and flew away, following their disciple. 

The two of them went down the mountains, seeing a bunch of people having fun on the plaza, then a couple of hours later, Tanjiro arrived at the Rengoku residence. Y/n landed on the roof and looked down, seeing Senjuro. They smiled, remembering the days when Senjuro was still a baby and how proud his father was. 

Their smile also disappeared when they remembered their last visit here when Ruka died. Y/n sighed, remembering why Shinjuro retired and what happened to him when he was a hashira. All of those thoughts are gone when they heard Shinjuro.
