"I promise, Rengoku-San. I'll train harder and I will keep on fighting to be the best Demon Slayer. I will always keep your words in mind and kill all the demons in this world..." I said. He smiles brightly at what I said and ruffles my hair. I swear on my life... I'll continue to carry on your will, Rengoku-San.

Y/N P.O.V

Rengoku-San invited Tanjiro to come with him to his house. He wants to give a book that will help Tanjiro master his Sun Breathing technique. Tanjiro asked me to come with him and I agreed, since I'm still worried for his well-being. Especially since he got stabbed during our last Mugen Train battle.

Tanjiro and I hold hands as we follow Rengoku-San, who is leading the way to his house. I'm a little nervous to meet Rengoku-San's family. What if he blame me for what happened to Rengoku-San.

"Y/N... are you worried?" Tanjiro asked, in a soft voice. I turn to look at him to see him staring at me with concern. "You've been silent the whole time..." he said. I just nod my head at what he said.

"I'm just worried that... what if Rengoku-San's father blamed me for what happened to him?" I said, in a soft voice. Tanjiro gives my hand a gentle squeeze to gain my attention. I turn my head to look at him again to see him smiling softly at me.

"I'm here with you, Y/N. I won't let Rengoku-San's father talk down on you..." he said. I just smile softly. Hearing him said that brought reassurance in my heart. He gently pulls me closer by my hand and gives a soft kiss on my forehead. 

"Thank you, Tanjiro..." I said. He smiles and gives my hand a gentle squeeze as a sign of reassuring me. I return the gesture and turn to look forward. There's a house in front of us that's slowly come to view. I'm guessing that is Rengoku-San's house.

"Here we are, you two..." Rengoku-San said, turning to look at the two of us. I straighten myself, feeling nervous once again. Rengoku-San makes his way inside the yard. I notice a young boy, turning to look at us. His eyes visibly lit up at the sight of Rengoku-San.

"Aniki!" The young boy said, while rushing towards Rengoku-San. So that's his little brother. I just smile as the young boy hugged Rengoku-San. It must be nice to have a sibling. You'd always have someone there for you. But I'm born as an only child, and I've been along for so long after mama passed away.

I've only started to know what it feels like to have someone by our side ever since I became a Hashira. But I truly felt that I have someone by my side after I met Tanjiro. I turn my head to look at Tanjiro who's just watching the siblings sharing a loving brotherly bond.

"Senjuro... this is Kamado Tanjiro and L/N Y/N. L/N here was the one who saved my life" Rengoku said, turning to look at us as he speaks. I flinch when he said my name. I turn my head to look at his brother as he grins at me.

"L/N-San... thank you so much for saving my brother's life!" He said, grabbing a hold of my hand with both of his and shakes it. I blink my eyes at how happy he looked. Eventually I start to smile and move my hand from Tanjiro's to pat his head gently.

"You're welcome, Senjuro-Kun. But I'm terribly sorry. Your brother lost his breathing technique because of me" I said. I feel a pat on my head. I turn my head to see Rengoku-San.

"I told you. Stop blaming yourself..." he said. I just smile sadly at what he said. Even though he kept telling me that, I can't stop myself from not blaming myself. After all, it's the truth. If I hadn't try to convince Rengoku-San to drink my blood, maybe he'd still have his techniques.

"I know what you're thinking, judging by the look on your face. It's true that after drinking your blood, I lost my techniques. But without it... I would have died, L/N. So don't blame yourself for it. I'll just have to find a new way to live" he said, smiling brightly at me.

"How can you still smile and act so happy..." I said in a hushed voice, but loud enough for him to hear me. "You are too positive about this. Even Shinazugawa-San starts blaming me..." I said.

"You!!" Someone yelled out. I turn my head to see a man. From his features, I can already tell that he's Rengoku-San's and Senjuro-Kun's father. He points his finger at me. "He's already useless even with his techniques. Now because of you! He lost them!! Now he's just a good for nothing child! He would have been better of dead!" He yelled. My eyes widened at what he said.

"Now that's just going to far! You have no idea how much she's been blaming herself for what happened to your son, sir. You don't have to be so rude!" Tanjiro said, stepping to stand in front of me. I just look down as I try to fight back my tears. Rengoku-San's father is clearly unhappy with the way Tanjiro speaks to him.

"Who the hell are you?" He said, glaring at Tanjiro. He notices the earrings Tanjiro is wearing. "You... you're a wielder of the Sun Breathing techniques, right?? Am I right??" He said, almost yelling at Tanjiro.

"Sun breathing?" Tanjiro said, staring at him with wide-eyes. Rengoku-San's father rushes towards him. He grab his arm, pushing him down to the ground.

I gasp at his action. 'He's really fast... those were no amateur moves' I thought to myself. Tanjiro looks in pain as he's being held down. I have to do something. Tanjiro is still hurt. I can't let him get hurt any further. But what can I do against this man? He's obviously not an ordinary person. What should I do?!
