"There are a few hundred members of the Demon Slayer Corps."
"The organization isn't officially recognized by the government. But it has existed since days of old and still hunts demons today."
"However the identity of the leader of the Demon Slayer Corps... is shrouded in mystery."
"Demons: Staple food: Humans. They kill humans and eat them. It's unclear when or where they first appeared."
"They have impressive physical abilities and their wounds heal quickly. They can reconnect served flesh and grow new flesh and grow new limbs. Some demons can change form. Others possess strange powers."
"The only ways to kill them are by exposing them to sunlight or by cutting off their heads with a special sword."
"The Demon Slayer Corps fight demons face-to-face. They are humans, so their wounds heal slower and their lost limbs don't return. Nonetheless, they fight demons in order to protect ordinary people."
You and Tanjiro listened to Sakonji. Though you have listened to this lecture about demons before, when you first meant Sakonji and Sabito. But you still listened, you listened with as much focus as you could.
"I am a trainer, just like it sounds I train swordsmen. There are many trainers. In different places, they have various training methods." Sakonji spoke, his words were serious. His tone made you pay attention whether you liked it or not. "In order to join the Demon Slayer Corps, you must survive the final selection at mount fujikasane. I decide whether you may attempt the final selection."
You side-eyed Tanjiro, his look was serious. He knew what he was going to try and do was serious or even deadly. You knew this too. You knew your brother put his life at risk every time he went on a mission.
"As you may know, Giyu is a demon slayer. In fact he is a hasira. A hashira is someone who is one of the top demon slayers. To become a hasira you must defeat one of the twelve moon demons or fifty normal demons as a Kinoe." Sakonji spoke, Tanjiro looked at you. He was confused. If you were married to him, why weren't you already a demon slayer- or a hasira?
"Um excuse me." Tanjiro spoke, raising his hand up lightly. You and Sakonji turned to him. "Yes, Tanjiro?" Sakonji asked. "Sorry if this is rude but If Giyu is a Hashira and Y/n is his wife how isn't she a hasira or even a demon slayer?" You looked at Tanjiro with wide eyes. Your jaw practically on the floor. Sakonji couldn't help but laugh at him causing his cheeks to heat up.
"Wh-what? Did I say something?" Tanjiro stammered. Looking back and forth at you and Sakonji. "Young Tanjiro, Y/n and Giyu are not married. They are siblings." Sakonji laughed. Tanjiro's eyes widened in horror. "I'm so sorry! I had no idea I-" "Just be quiet Tanjiro." You said putting your face into your hands as Tanjiro's face lit up several shades of pink.

"Hey Tanjiro." You spoke. "Yeah?" Tanjiro spoke, his voice was groggily from how you woke him up from his state where he was almost asleep. "Um thank you." You spoke, Tanjiro cocked a brow though you couldn't see his expression from how dark the room you two stayed in were. "For what?" He asked, "For being a good training partner with me and friend."
Tanjiro's eyes widened a bit at your words, he was sure you two were training partners but he didn't know if you two thought of you two as friends. You two didn't know much about each other other than the fact that you were siblings with Giyu the water hasira and that you loved rice balls and mochi. Tanjiro was always a bit intimidated to ask you about your life, though he never knew why.
"No problem Y/n." He spoke, "I know we don't know each other well even though we have known each other for a little bit but I just wanted you to know I do appreciate you and I hope we can get closer." You said. "I would like that." Tanjiro spoke, "I would like that to Tanjiro."

Entry One
Starting today, I have decided to write in this journal for Nezuko. Again today, I descended the mountain. I train as hard as I can so I won't die during the final selection. I go down the mountain repeatedly with Y/n day after day. I've become quite good at avoiding the traps. But not as good as Y/n. She can go through the course easily, and not even be touched by a single trap. The only ones she seems to struggle with are the swinging logs. But again, she doesn't get hit only does she move in the nick of time. She has a lot of stamina, she's quick on her feet as well. But while she gets stronger so am I, my nose is even sharper at picking up scents now.
Entry Two
Today we advanced the traps and got much deadlier, it's like he wants to kill us. But every time they advance I see Y/n only get better at dodging and running. It shocks me how quickly she can adapt to things. I should ask her sometime how she is so quick on her feet. But today we went down the mountain with katanas. It really gets in the way, so carrying it got me in a lot of traps. But Y/n ran down the mountain just like she did without the katana which was shocking. But when she would see me stuck in a trap or hear me yelling she would stop and come help me get out, she always had a smile on her face like she never cared if she wanted to help me out.
Entry Three
Today I practiced swinging the sword. I say "Today" a lot but lately this is what I do everyday. After descending the mountain, I swing the sword so much I feel like my arms might fall off. But even after we do all that Y/n still wants to keep going, she's a really hard worker. It's almost crazy. Sometimes when we go down the mountain I don't even see her break a sweat. Not to mention she looks really good doing it, not like that though! I'm not being I creep I swear! She's just good and running down the mountain and swinging her sword really!
But anyway, the first thing he taught me was that a katana breaks easily. It's strong against force lengthwise but weak against force from the side. With a katana, you must attack straight ahead. When you swing a katana, the direction of the blade and the direction of the force you apply must be exactly the same. Furthermore... if you damage the sword, he will... in other words, if I or Y/n break it... He'll break our bones. His threats are cold... like the mountain...
But today I also learned Y/n is the youngest out of her siblings but I was the oldest out of ours even though we both are thirteen. She says she thinks that I was probably the best older brother because of how caring I am, I couldn't help but blush at the comment, it was really kind of her.
Entry Four
Today Y/n and I did nothing but fall down... We are training to break our fall and get up quickly. Urokodaki had Y/n and I fight to practice. But when I would come at her armed, she would take me down quickly. When I tried taking her down I would end up getting taken down. Which became a pain, but I soon saw her get taken down when she and Sakonji fought. But she gets up just as fast as he takes her down.
When Urokodaki finished out training Y/n offered to help me with takedowns. I still fell a ton of times until she pointed out my stance, she helped me fix it and I even took her down once!
Entry Five
Today we learned breathing and some standard forms. Y/n knew a lot of them already and even how to control her breathing. But I ended up getting hit in the stomach because Urokodaki said I didn't have enough strength in my core. But when he walked away upset, Y/n helped me up and taught me some small tricks to help me out on figuring out how to breathe. It helped a lot really, and for some reason I got really nervous and tense when she touched my chest. Maybe I was scared that I was going to get hit again.
Entry Six
I have been writing for six months, Nezuko, and you still haven't woken up. Urokodaki immediately called a doctor to look at you... but he found nothing wrong. I was scared. I thought I'd wake up in the morning to find you dead. And... that's still how I feel every night. And every day Y/n and I go higher on the mountain for our training everytime we go higher I think we might die, I'm finally seeing Y/n tired during training. Her breathing is heavy and she looks just as tired as me at some points. But even when we are training she tells me to control my breathing and relax and to not lose focus. She also reassures me often that you will be ok, and that you are just getting a long amount of rest. Or she says you are doing all the resting I can't do for me. I really appreciate her, she keeps me going during training. She also brushes your hair for you. She's a really sweet girl.
"I have nothing more to teach you two." Sakonji spoke, you and Tanjiro breathing heavily from your training you just finished. "What?" Tanjiro and I said at the same time. "The rest is up to you two... you two can take what I have taught you and bring it to the next level?" Sakonji spoke. We both stared at him as if he was mad, Tanjiro and I both thought we had so much more training left to do.
Sakonji raised his hand and motioned us to follow him, which is exactly what we did. Tanjiro and I almost had to drag our legs behind us to keep up with him. But the walk was quick/ Sakonji led us into the woods where we quickly stopped. Tanjiro and I both looked around in the woods seeing nothing but a little bit of open land and many trees.
"If you two can split this bloudler, I will approve you two for the final selection." You and Tanjiro whipped your head to Sakonji. You both were looking at him like he was a mad man. But you both turned your head to the boulder. Thoughts clouded your mind, you knew you couldn't break this boulder. Hell that wasn't even possible. In now way was that possible.
"Urokodaki! Wait! This... Urokodaki!" Tanjiro yelled. You turned your head and watched as Sakonji walked away from you both, and from that day on. He didn't teach either of you anything.
•·.·''·.·•·.·''·.·•·.·''·.·•·.·''·.·•
Tanjiro and I were clanging our swords against the boulder. We do this all day every day, with no breaks. I breathed heavily as I raised my sword and hit the boulder, it didn't budge. All I got in return from hitting it was a tingle running up my back from the vibration of the sword making contact with it. Tanjiro tried to hit the boulder as well, but he also failed.
Never in my days of all my training and fighting have I ever felt the way I do now. Nor have I ever felt this feeling. It made my chest feel sticky and my face felt hot. I dropped to my knees and my sword fell next to me. Tanjiro looked over at me hearing the clang of my sword hitting the ground.
"Y/n? What are you doing?" he questioned. "Tanjiro, I can't do it." You said, that was the first time you had ever said those words. Even during your training you never said those words even when you failed. You always knew you would get it at some point but as of now, you felt like you really couldn't.
"Y/n..." Tanjiro spoke. Tanjiro was losing hope too, but after seeing you lose hope he felt as if you both really didn't have a chance anymore. You were always there to encourage you two that you both could do it. But now, seeing you on the ground saying you couldn't made him really think you both were never going to do it.
"I'm never going to be a demon slayer, I'm just going to be known as Giyu the water hasira's sister." You spoke, Tanjiro watched as you looked down at the ground. Your hands gripping the fabric of your pants as tears stained the dry dirt ground. Tanjiro gripped the grip of his sword and began swinging angrily at the boulder.
"Just break already!" Tanjiro yelled, his sword hitting the boulder many times. You looked up at Tanjiro, the look on his face was anger. You were so angry you couldn't break the boulder. You grabbed your sword and rose to your feet swinging your sword at the boulder. You and Tanjiro began yelling together.
"Break!" You yelled.
"Just break already!" Tanjiro yelled back
"You stupid boulder!" You shouted.
"Come on! We have to try harder!" Tanjiro screamed.
"Silence!"
You and Tanjiro froze, the voice that had just yelled wasn't either of you. You and Tanjiro looked up to see a boy in a fox mask sitting on the boulder.
"A man and a woman shouldn't whine... it's unseemly." Your eyes were wide at the boy, you weren't even able to feel his presence. Who was this kid? "Whatever the suffering, bear it in silence... If you both are grown. Or are you two still children?" The boy spoke, you and Tanjiro looked at the boy in the fox mask in shock as he hopped down from the boulder.
Once the boy's feet hit the ground, he drew his sword quickly and hit Tanjiro. But Tanjiro was quick enough to block. But while Tanjiro blocked he kicked him in the stomach causing him to fly back.
"Tanjiro!" You yelled, dropping your blade and rushing over to him. Tanjiro gripped his stomach in pain. "I'm fine Y/n." Tanjiro smiled weakly. But the boy in the mask threw his sword at you. The grip of his sword hitting your back and causing you to grab your back in pain, the boy in the mask quickly kicked you in the back causing you to fall onto Tanjiro and let out a loud groan.
"The boy, you're slow. And weak. The girl, you care too much about others. Making you weak. You both are weak and immature. You both will never be demon slayers."
