Nezuko was able to make it to the village. She thought to herself, "The charcoal is almost gone. I never thought it was never get it done. " 

"Nezuko! Can you help me out with this? " A villager asks politely, to the girl, as she is a frequent visitor to the village. 

"Of course, I would be right there." She replied to the villager as she helps the villager of what needs to be done. 

Although it has been a habit of helping people as much as possible, she always liked of the people she helped being nice to one other. 

Although she often thought of her family she left behind. She thought , "I hope that Tanjro and the rest of the family is ok. I mean, I know they can handle themselves , as much they can. Although... Tanjro can be a troublesome boy at some times." 

As she was walking back to her house on the mountain, a villager named Mr. Saburo looks at the young girl with total concern. 

"Hey, Nezuko! You walking back to your house this late?" He asks her as Nezuko nods at the man with total ease, "Yeah, I just finished selling the charcoal I've gotten all day. It wasn't an easy attempt of selling them , but I managed to get it all done thankfully." 

"Damn. I never thought of a girl like you would have to do that all by herself. How about you stay over for the night?" Saburo offered her as the girl seems to be scared of his offer. 

"Mr. Saburo, I'm going to be fine, you don't have to do that." She said, as she tries to persuade the villager that she is trying to decline his invation of coming into his home, as she felt totally unease of just being in somebody's home without consideration.

"I insist. It's way too dark for you to travel at night. Besides, I'll be grateful if you do come in." 

The girl sighs as if Saburo wouldn't let go of her decline as she knows him too well ever since he lived near her home. 

"All right, I'll come in." She sighs as she drops the basket down as she took off her shoes and eaten her dinner that Saburo had made for her. 

As the girl looks at Saburo, her mind seems to have concern and curious thoughts as he said, "It's a good thing you decided to stay for the night. That is when demons would appear and attack people at night." 

" 'Demons?" Nezuko thought in her mind, as the man continues on, "Demons are nothing but flesh-eating monsters. It's a good thing we have someone watching over us. They're called , "Demon Slayers." 

The thought of the demons coming , races through Nezuko's mind, due to being worried about her family that was waiting for her back home. 

"Mr. Saburo, you don't think that there is a possibility of a demon would actually attack a home filled with humans, don't you?" 

Saburo reassures the young girl , "I'm not entirely sure if I can answer that question, Nezuko. You never encounter a demon before, have you? " 

The girl was silent at the man's question, as if she was unsure of the question herself. 

"You better get some sleep. You should be able to leave in the morning." Saburo said, as he went away to let the girl sleep on the bed that was made for her.

"Well, I guess that it would be nice to sleep for once." Nezuko thought to herself, as she felt her eyes were falling asleep as she slept in total peace, as the night went on. 

Nezuko was awake early the next morning, as she waves to the man as he said, "Are you going to be able to find your way back?"

She nods at the man, "Yes, I will! Don't worry and thanks for last night!" 

She walks back to her house through the trees, but then... all the feelings she had , turns to concern and bitter as she sniffs the air. 

"Is that a smell of blood?" She asks , as she quickly races through the forest towards her house. 

In front of her, was something that frighten her. It was Tanjiro , holding her brother, Shigeru, being dead! 

"Tanjiro, Shigeru! What happened, please wake up!" 

Neither of them respond as she walks towards the opened bloody door, as to her quick and terrifying discovery, her mother, Hanako, Takeo , and Rokuta dead as well. 

"No... Mom, Hanako, Takeo, Rokuta! They've been killed by a demon!" She said, as she was sadded by knowing the horrible truth that held in front of her. 

She checks again, but to her amazement, it seems that Tanjiro wasn't dead, but seems to be unconious with injuries from the attack. 

"Tanjiro. I guess we're the only siblings left in the family now." She said, as she gather enough courage she had within her , as she carries her older brother into the woods alone. 

"I can't believe this actually happened! If I haven't stayed at Surbuo's house, Tanjiro and the rest of our family would've survived . It's my fault." She thought. 

Unknown to her, Tanjiro felt a urge to get up. He was relentless , as he struggles against his younger sister's back. 

"Tanjiro? Wait, be still!" She said, but they fall backwards from a steep hill, as she was hit by a tree nearby. 

As she was about to get up, Tanjiro was going to attack her. With her quick thinking, she grabs a wooden bamboo stick as to stop the attack. 

As she looks at her brother, she was shocked of what has become of her older brother. 

"Tanjiro... He's become a demon!" She thought in shock . 

"Tanjiro! I'm so sorry! I should've protected you! I feel so helpless without you! Please don't let the demon control you, I know you wouldn't hurt me! " Nezuko yelled at her demon brother.

As to her surprise, she notices that he understood her, as he was crying , to not to hurt the sibling that he has left. 

"Tanijro, you heard me, haven't you? I'm so relieved." Nezuko said, sigh of relief that her older brother had heard her voice. 

As the siblings were having a decent family bonding, Tanjiro heard something unfamiliar, as someone was coming up behind them.

Nezuko notices it as well as she hugs her brother, moving from the sudden attacker, as they rolled against each other as they hit a tree with the sword cut off the bun of her handkerchief that held her hair. 

She got up from the tree as without hesitance, the attacker held her brother with one arm as he was growling. 

"Tanjiro!" Nezuko yells , afraid of loosing her brother again, as the attacker looked at her with a curious and angry expression on his face. 

"You're a girl with a demon. Why you so fascinated with it?" He asks Nezuko. 

Nezuko seems to be in shock of the question, as she was mad at the attacker, "You think by calling that demon an it?

Yes, I'm with that demon, I'm protecting him, you don't understand!" She said. 

"Oh, enlighten me?" He asks, seems to be curious of her explanation of why she was trying to protect the demon.

"That demon is my older brother, Tanjiro! He has been transformed into a demon while my family was slaughtered by a demon! 

I wasn't there when the attack happened, so you have to let my brother go! " 

The attacker said, "I see. Then you wouldn't mind if I kill your brother right here and now?"

"No! I will find a way, a way of restoring Tanjiro's demonized form, to turn him back into a human, and while I'll be doing that, I'm also going to find the demon who murdered my family! 

There will always a way if you believe in it! Tanjiro isn't a flesh -eating demon! I know him better than anyone! 

He wouldn't harm a human!" She yells at the attacker.

The attacker was irate as he yells, "There is no such thing as a demon would control his own feelings!" 

He stabs Tanjiro as he groans in pain.

"Let him go!" Nezuko yells as she thew a rock at the attacker to get his attention. 

She was rushing through to get Tanjiro back from the attacker, as she was trying to attack him.

She threw the axe that her younger brother, Takeo used, and threw it up in the air, without the attacker noticing. 

Nezuko continues to charge towards the attacker, as the attacker knocked her out with his sword. 

The attacker looked around, but then when the axe came from earlier, he was shocked and amazed of her strategy against him.

"She knew she was defenseless , and yet, she charged straightforward towards me without me noticing. That girl was something else."  He thought.

Tanjiro notices his younger sister being unconious as the demon boy couldn't bear it any longer. He growls in anger as he pushed the attacker from him as the attacker was unprepared of his opponent's dismay.

"Oh , crap! He's going to harm her! " He thought, but then to his amazement , Tanjiro makes a defensive shield on his sister. 

The attacker remembers what Nezuko had said. "Tanjiro isn't a flesh-eating demon! I know him better than anyone! He wouldn't harm a human!" 

Tanjiro continues to go forth as the attacker thought in his mind, "I never thought this would happen. 

I saw what demons were capable of, their thirst for human blood is unbearable. So unbearable that the demon would eventually drank the blood on the first sight they see , even if it is by their own family blood. 

But this boy, he was injured when the demon attack happened, he continues to pry on, with all the remaining strength he had left within him. 

The attacker stops midway, as he and Tanjiro collide for attacking each other, as he uses a gentle, sharp karate chop on the boy's neck to collapse the demon boy to the ground. 

The attacker seems to be fond of the siblings, and so, he makes a bamboo gag on Tanjiro, so he wouldn't attack anyone else. 

He also places a blanket to cover the siblings and waited for Nezuko to be waken. 

Nezuko was still unconious , but a gentle voice came towards her, as she knew who it was. It was her deceased mother. 

She looks at her daughter, "Nezuko. I'm so sorry that I left you with Tanjiro all alone. Please take care of him for me." 

Nezuko woken up so suddenly, as she notices Tanjiro sleeping next to her. 

"I see you're awake . Are you feeling any better?" The attacker asks. 

"Yeah, I think so. Wait, why you being so nice to me all of a sudden?" She asks. 

"Let's say that it's a conscience . Listen to me carefully. You have to seek out a man named Mr. Sakonji Urokodaki.

Tell him that Giyu Tomioka had sent you. That's my name by the way. I never intend of revealing my name to anyone else before. " 

Nezuko was amazed by Giyu's kindness. "Thanks for everything and believing in me, Giyu. I really appreciate it. I haven't introduce myself properly. My name is Nezuko Kamado." 

Giyu was silent for a moment, as he looks at Nezuko for a long time as he said, "I'll be leaving now, Nezuko." 

The Demon Slayer vanishes as Nezuko looks at her older demon brother. 

Nezuko and Tanjro went back to their wooden house. 

Nezuko took a heavy heart as she glances one finally look at their family. 

"Takeo. Hanako. Shigeru. Rokuta. Mom. I'm so sorry that I have failed to protect all of you. We'll be fine." She thought as she buries the dead bodies near the home. 

She prayed in total silence, to pay the respect of their loved ones. 

Now all she has to do is to become a Demon Slayer, to protect Tanjiro from other demons and fulfill the promise to restore his human form.

The demon boy looks at his younger sister with a curious expression on his face. 

She smiles as she takes Tanjiro's hand, "Let's go, Tanjiro." 

Now it is time for Nezuko and Tanjiro's journey to begin.
