It was right after Nezuko had sliced the morphed demon. The demon was fading as Nezuko smells the demon. 

She said in a sad smile, "You really had a tough time, haven't you? What a sad scent I have gotten from you." 

She held the demon's hand as the demon as she prays, "Please, let the demon be reborn, please don't make him into a demon and let him have happiness in his life once again." 

She notices the hand totally disappeared as she knew that the demon must've found his way back to where he once belonged. 

Nezuko smiles a bit, thinking about her friends that she had treasured so much, and it really made her happy that her friends would be in total peace now since the demon that killed them had finally been slayed for their sake. 

"Sabito, Makomo, and every disciple that Sensei had taught over the years, I did it. I slayed the demon, the very demon that killed all of you. I know that it must've been hard , but you guys can be at ease now. 

I know that we known each other for short period of time, but thank you for everything you taught me . I know you're going back home at Mt. Sagiri and be with our Sensei once again."  She thought , "If I died too, my soul would've gone there too." 

Nezuko knew that there isn't time to be staying in once place, she has two keep on going, no matter what it takes. 

Nezuko asks one of the demons she had encountered, "I have to ask you something very important!

How can I possibly turn a demon back to a human being?" 

The demon ingroes her question as she has to slay it, as it attacks her without hesitant. 

Nezuko notices more demons as she knew she had to slay each one of them, she thought about her brother, as she launches the attacks head-on, "Please. How can I turn Tanjiro back, back to his human form?" 

Nezuko kept on running through the forest, as she possibly can , to be away from the demons. 

As she stops from running to rest, she notices that she was somewhere with the Wisteria flower blossoms.

She said in total amazement, "Wisteria flowers? Wow, what you know? I actually made it! Man, talk about lucky." 

She turns around to be in total shock of where the other trainees are , as she realizes that there were only four people who was able to pass the Final Selection. 

"No way, don't tell me. It's just the four of us? But I remember that they were at least twenty people when it first began. 

They must've been eaten by the demons. How horrible." She thought. 

She turns to see a boy with yellow hair said, "I'm going to die, I'm a goner. Even if I survived now, I'm going to die anyway." 

"Geez, this guy is very optimistic about this. I'm amazed that he actually made into being a Demon Slayer." She thought of seeing the boy next to her. 

The girls said, "Welcome back. We're glad you all make it back safe and sound." 

Nezuko thought, "Well, they make it sound like it was an easy task. It wasn't an easy task to get back here, the demons were really hard to slay. " 

One of the finalist asks, "So what I should do now? Where's my sword?"

The girl replied, "First we should shall issue you with uniforms. We will take measurements after which your rank will be engraved. " 

"There are ten ranks in all. Kinoe.,Kinoto, Hinoe, Hinoto, Tsuchione , Tsuchinoto. Kanoe, Kanote ,  Mizunoe and Mizunoto." 

Nezuko thought, "Oh, so those are the Demon Slayer ranks' names. That seems interesting." 

The girls explain, "You are in the lowest rank, Mizunoto. 

The finalist asks, "And what about our swords?"

"Today, we will allow you to choose the one for your swords. " 

Nezuko tilted her head in confusion, "What does that mean?"

"However the swords will take ten to fifteen days for it to be competed. " 

The finalist rolls his eyes, "You have to be kidding me! " 

"But we have something to show you first before you chose your sword. " The girl said, as the girls clapped. 

Nezuko looks up to see crows flying down on their shoulders. 

"You now own a Kasugai Crow. " 

Nezuko looks at the crow, "Um, what is a Kasugai Crow?"

"These Kasugai Crow is used to primary to provide communication." The girl explains as Nezuko was amazed. 

The yellow boy ask, "Um, why do I have a sparrow instead of a crow?" 

The Finalist boy yell, "I don't need any of this! " 

He walks up as Nezuko watches. 

"Who needs some stupid crow anyway?!? " He said, as he grabs one of the girls' head by fierce force, as Nezuko gasps in shock of what he has been doing to her. 

"I want my sword now. You hear me right?" He said, "Give me the Demon Slayer's sword right now!" 

Nezuko couldn't handle the boy's attitude any longer, as she despised of it, as she gets there and grabs the boy's hanoi . 

"I have enough of your attitude! Take your fifthly hand off of her right now!" She said , defending the girl, "Or else I will personally break your arm." 

The boy said, "Just who you think you are, some sort of heroine? 

Let's see how you really are!" 

Nezuko didn't reply back to him, as she uses her reflex on the arm as the boy groan in pain of it. 

The boy stares at Nezuko who seems to be irate at him, by staring into the boy's eyes. 

The girl asks, "Are you done chatting now? " 

The girl showed them the steel as she said, "Please, select one." 

Nezuko was amazed by the steel, as there was so many. 

Nezuko thought, "How am I know which one is the right one for me? They tell me to choose one, right?

It's my first time seeing an Ore before, so I guess I have to do something." 

Nezuko looks at it after a while, but then she uses her nose to sniff the right one for herself.

Meanwhile somewhere, a man seems to felt the aura, "Ah, it seems like my children has been increased once again. 

I begin to wonder, what type of swordsmen would they be?"

Nezuko begins her long journey back to Tanjiro and her Sensei. 

"I was so naive, I haven't gotten a chance to talk to the demon about Tanjiro. They appeared out of nowhere, attacking me one by one. " She said, "Talk about a waste of opportunity. 

I'm so sorry, Tanjiro." 

She collapse, "Man, this uniform I have gotten is so heavy. I have to return home as soon as possible. I have to see Tanjiro again."

She finally arrives at the house, as she breathes in relief she has made it all the way . 

Then suddenly, after six months, the door was flung open, kicked headfirst, as Nezuko couldn't believe her eyes. 

In front of her, was her brother who has finally awoken from his slumber. 

"What the- Tanjiro!" Nezuko yells at her brother who saw her, "You finally decided to wake up?!?" 

Tanjiro runs up to her as Nezuko said, "Tanjiro, uh!" 

She collapse but Tanjiro hugged her as he was crying silently that his sister had come back safely. 

"Tanjiro, why you.. Why you fell asleep this entire time, huh? You never awoke up! I was completely worried. Don't do that to me! " 

Sakonji was nearby, caring wood, as he saw that his student had come back alive! 

He drops them as he embraces the siblings as he tells Nezuko, "Nezuko, you came back to us alive." 

Nezuko told her sensei about what happened at the Final Selection as Sakonji seems to be amazed of her encounter with the morphed demon.

"I see. It was you who finally faced and killed the morphed demon. I have to say , that's quite an understatement." He said. 

Nezuko has a bandage on her forehead as she nods at her sensei's comment, "Yes, I did kill the demon, but I never would've suspected that you were once a Demon Slayer like me." 

"I'm sorry that I kept that a secret from you, Nezuko." He apologizes to her. 

"There is several different demons out there, you know. There are demons who have a special spell called, "Demon Blood Art," which has supernatural abilities ." 

Nezuko gasps of the revelation, as she asks, "Is there a possibility that Tanjiro may have that ability?"

"I'm not entirely sure about that, but there would be a chance you might encounter those types of demons, Nezuko." He replied back as Nezuko sighs. 

"I'm sure you'll be fine, Nezuko. I believe in you." Sakonji said. 

Nezuko smiles a bit at the reassurance of her sensei's word, "You're right, Sensei." 

Nezuko ask, "So, I guess Tanjiro's Demon Blood Art must be unique. But do you know why he sleeps?" 

"It's a guess, but I think he's just sleeping to recover his strength, instead of consuming human blood." Sakonji explains. 

Nezuko smiles as she thought, "It's going to be fine, Tanjiro. I'm here for you." 

It has been fifteen days later, Nezuko's sword has finally being forged. 

There was a man approaching , as Nezuko was confused by the man who had forged her sword. 

"Ok, that's a sight to behold." She said. 

She said, "I take it you're the person who forged my sword, correct?"

The man nods, "Yes, my name is Haganezuka. " 

He went towards her as revealing a clown red face, "Whoa! A clown face, well, that's a new one. Please... come inside." 

Mr. Haganezuka said, "Com'on, draw your new sword out! I want to see the color of the blade! 

Nichirin Swords also mean, "Changing Swords." They change color depending on the bearer themselves." 

"Really, that's amazing!" Nezuko said. 

She drew the sword as the blade changes the color to bright black sword. 

She turns to her sensei and Mr. Hagnezuka, as she asks, "Is this normal? Of having a black sword?"

"Well, it is a rare occasion, Nezuko. It's very rare of a bearer to have a black sword. " 

Suddenly, her crow appears to the group, "Nezuko Kamado! Here are your orders!" 

"I'm having my first mission already? Talk about traveling news fast!" Nezuko said in blinking in surprise that she'll have her first mission as a Demon Slayer. 

"Make your way to a town to the northwest! There are young girls who had been vanished there!

Night after night, they kept disappearing! Hunt the demon there and kill it!

Nezuko Kamado, prepare yourself for this task! This is your first task as a Demon Hunter!" 

Nezuko seems to be totally in awe of having her first assignment as a Demon Slayer. 

"Ok, I have to be all out for this mission. " She thought, "I've made it this far, there is no point of stopping now."
