3rd Person's POV

5 days passed since Y/N and Tanjiro returned and became official members of the Demon Slaying Corps. Y/N sat down near Nezuko who hides under the futon, which made Y/N smile and pat her head to calm her down. Urokodaki is away to get firewood... Until-

"Y/N-san! He's here!" Tanjiro barges in with a look of excitement on his face.

"Who?" he asks confused

"The swords!" he answers

"Oh..."

Y/N had no choice but to stand up and went out, he saw a figure walking and carrying a long box under his arm.

"Hello, Blacksmith-" 

"Are you Y/N L/N?" he asks

"Straight to business are we. Yes, I am Y/N L/N"

"I am Mako Teriyaki, I am assigned to make the finest and strongest sword for you to use and slay demons" he introduces himself

"Did I hear that right? Teriyaki?" Y/N asks, making sure while trying his hardest to not let out a laugh or snicker.

"YES! Now shut it and let me finish!" he shouted to which the straw hat that covers his face now reveals a goofy-looking mask. Surprising the two.

"Sorry... Let's continue this inside with cups of tea" Y/N offers as they lead him inside.

"Ummm... Teriyaki-san-" Tanjiro was about to ask when Mako cuts him off

"Mako-san!" he corrects Tanjiro

"Mako-san! I wish to know if you're also the one to make a sword for me?" he asks only to receive a *tsk* from the blacksmith

"No" he answered, letting Tanjiro know how annoyed he is from interrupting him. Tanjiro felt embarrassed after this.

Mako placed the box in front of him and slowly removes the cover to reveal a beautiful sword that is sheathed in a white scabbard.

"Wow, it is beautiful" Y/N commented, but Mako shook his head

"It's not done yet. You must hold the sword to see what color it will become" he explained to which Y/N then grabs the sword and unsheathes it and noticed how light it is, he raise it up as the blade started to turn pure black.

"What the fuck!" Mako exclaims

"What?! What's wrong?! Is black a bad sign?!" Y/N said scared out by the Blacksmith's reaction

"Does black mean a bad omen?" Tanjiro says, worried

"What? No! I've never seen a blade this dark of a shade of black!" he explains which calms both Y/N and Tanjiro a little. "But-" he grabs Y/N by the collar of his kimono, "I will promise you, Y/N-san! That I will lend you my services every time you need a new sword!" he says getting too close to Y/N's face

"Ah... Can't I just sharpen it-"

"Nonsense! After seeing your blade this rare of a color! I need to make sure why! This greatly interests me!" he said with passion and joy for some reason.

"Oh, ok" Y/N answers

"Then, it's time for me to leave! I need to report this to the village as soon as possible!" he says as he stands up and left the house in a hurry.

"Goodbye, Teriyaki-san!" Tanjiro bids farewell with a wave

"Mako-san! You brat!" he shouted back while speed walking away to the horizon until his figure is too small to be seen by the human eye.

"This seems like I'll be the first to be sent out to do missions, Tanjiro" Y/N said while sheathing his new sword to its scabbard.

Hearing this, Nezuko jumps up and hugs Y/N's leg, due to her fear of daylight she went to a small size. For Y/N, she saw how adorable Nezuko looks as she stares up at him with pleading eyes. For Tanjiro, he is fuming in anger, seeing her little sister be this close to a guy. In the end, Tanjiro lets it be and sighs. Not wanting to make his sister sad.

"Don't worry guys, it will probably take a while for me to receive a mission from HQ" Y/N says, but soon interrupted by the *Caws* of his Kasugai Crow.

He lifts his left arm as the Crow landed on it, "*Caw* Mission from HQ. *Caw* For Y/N L/N. *Caw* To the north, you are tasked to eradicate demons that gather there *Caw*" it says while cawing, which Y/N pets it head, appreciating the Kasugai Crow's work to deliver his first task.

"Seems like you're leaving early" Urokodaki enters, already heard all of it.

"Yes, Urokodaki-sensei. I will set out early so that I could return quickly" he says as he pulls out the Demon Slayer uniform that he received yesterday.

===

Noon came, Y/N now in his Demon Slayer uniform with his White Haori over it. He embraces Urokodaki then Nezuko in a farewell embrace, he had a hard time making Nezuko let go of him but she manages to believe in him. Tanjiro waits for Y/N in the doorway with his sword in his hand.

"Be careful out there, Y/N-san" he says as Y/N grabs his sword and pulled Tanjiro in a hug before he says his farewell and went out to his first mission.

Y/N's POV

"You know? I'm lucky to have you as my Kasugai Crow. I saw how Tanjiro's Kasugai Crow treated him, poor Tanjiro." I'm talking to my Kasugai Crow who now rests on my shoulder while listening to every word I say. He will only respond by nodding and shaking to our conversation.

Walking through a dirt road with a scenic green landscape calms my nerve while traveling on foot.

"Hey, am I your first assigned owner?" I ask, he shook his head no, "Oh, what happened to your last owner?" and this time it looks down to which I understand what he is trying to convey. "Sorry... I didn't mean to..." I said as we then travel in silence.

While walking, I remembered something from what the twins at the Final Selection say about Kasugai Crows. I raised my hand and the crow knew what this means, jumped, and landed on my finger, now looking at me.

"Is it true that you can transfer messages or letters to other people?" I ask him, he answers with a nod. "Thank you, I really need to know that." I said as I place him on my head to which he began to rests on it.

'Maybe I should send anonymous letters to Shinobu and Kanao when I have the chance. But that will lead to them knowing I'm part of the Demon Slayers now. Also, I didn't know what happened if Kanao even told her that she saw me. Agh! All this thinking only hurts my brain!' I thought as I slap both sides of my face, waking up the crow but soon went back to sleep again.

===

Night came, I finally arrive at the Wisteria House to try and gather more information about my task, not too far from here.

"Hello? Anybody here?" I called out after knocking on the front gate.

"A demon slayer?! Please come in, come in!" A mid-age woman greeted me and opens the gate.

"Sorry for intruding, I wish to know more about my task here"

"Ah! Do you mean the demon eradication mission near the lake north from here?" she asks to which I nodded. "Well, I don't have much intel for you. But what I do know is 5 separate Kanoe rank slayers are sent there but didn't return." she explains which made me confused at first

"Wait, Kanoe rank? But, I'm just a Mizunoto?!" I said to which she smiles, this time, I felt a different vibe coming off her.

"The rank means nothing if you are strong. The Corps made the rank system to keep a check on the recruits and lower ranks" she says, my gut tells me that she's probably lying to make me feel confident for this mission.

"Fine. I have no choice anyway. This is what I signed up for." I said as she gives me a map that shows the exact location to where the missing slayers went to.

===

After several miles of walking with my arm resting on the hilt, while my other free hand is clutching on the map she gave me. I released a sigh of irritation, tucking the map away.

"5 higher rank demon slayers didn't report back. Now they sent me, a Mizunoto?" I said to no one but myself.

*Caw* *Caw*

I look up and reached out my arm to see my Kasugai Crow descending and landed on my arm.

"Demons gathering in an open area. *Caw* Villagers are surrounded ahead! Hurry! *Caw*" he says as I quickly move in faster, the crow flew off to the sky.

'Shit, I need to be faster. Faster. Faster. FASTER.' I repeated and with Total Concentration, I dashed through the woods, leaving a trail of fire on my steps.

Reaching the opening, just like what my Kasugai Crow told me, demons of various sizes gather with villagers grouped and surrounded. I wish I had more time to analyze the situation, but the villagers' lives matter most. I unsheathed my sword and dashed into the nearby demons.

"Water Breathing - Third Form: Flowing Dance" as I moved in and decapitated the weak-looking demons in a flow-like dance. Taking out the multiple weak ones first is a better choice, this will only leave the stronger few to fight.

"Another demon slayer? Is sending 5 slayers in a row isn't enough? You weaklings truly don't understand, I am going to become part of the 12 moons!" the demon, seems average like the rest but my guts tell me that I shouldn't judge by the looks. "Get him!" he commands to his two demons beside him.

The two demons lunge at me to attack but I dodge each of their attacks, the first demon uses its sharp claws to slash at me with agile as the other uses its brute strength. Each target to eliminate me. I breathed and dashed forward between them, exposing their flanks.

"Flame Breathing - Fourth Form: Blooming Flame Undulation" I sliced each of their arms and then their heads as they scream while their body turns to nothing.

3rd Person's POV

Y/N readies his blade, focusing on the last demon that commands the weaker ones. Seeing his own minions dead, the demon roars angrily at the air. This scares the terrified villagers more as Y/N stood his ground.

"You fool! Now you dare to face me!" the demon roars, Y/N senses the demon's killing intent.

"Run!" Y/N shouted to the villagers and the scared villagers began running away from the demon in a safer direction.

"Blood Demon Art: Acidic-" the demon was about to use its Blood Demon Art but stops midway as Y/N appear in front of him from a blur, his sword ready for the killing blow. "Blood Demon Art: Concentrated Acid" the demon released a direct spray of liquid to Y/N to which he soon rolls to the side, but the liquid touched his right shoulder.

He released a hiss of pain and look to see the liquid eat away the part of his clothing and burn his skin. Clutches his arm in pain, as he looks up at the demon who has a smirk on its face.

"Hurts doesn't it? Lucky for you, I let you live. Hihi~ I enjoy watching my prey in pain before I devour them." it says, as it mocks Y/N

Now knowing what happened to the previous demon slayers, nerves pops on his forehead, he hissed, releasing a weird sound from his mouth.

"Flame Breathing - First Form: Unknowing Fire" he disappears, then appeared beside the demon and sliced its arm off.

However, the demon's lost arm will soon be replaced with a new one thanks to its demonic regeneration. Threw a punch at Y/N to which he uses his blade to block. Y/N held the demon's attack but noticed that once his blade scratches the demon's hand, its blood hisses like it's some kind of acid too.

"You can't kill me that easy! You'll die before you could even slice my head!" it mocks him again, this time with a burst of annoying laughter.

"Shut up!" Y/N roars fueled with anger, use Total Concentration Breathing, and sliced the demon's arm off again. This time, both of its arms.

The demon laughs as it uses its acidic blood to splash on the demon slayer, but what it didn't expect is when Y/N charges through the acid as it touches his upper body and blocks his head with his arms.

"Total Concentration, Water Breathing - First Form: Water Surface Slash" he says, and decapitated the demon that proclaims itself to be a candidate to join the 12 moons.

"E-Eh?" it yelps in confusion until it noticed that his body disintegrating. "W-What?! It can't be! I was supposed to be a powerful demon! I had loyal followers of demons that supported me!" it ranted while its head starting from the neck is crumbling to nothing. Y/N walks up to it and raised his foot over its head.

"Die you piece of shit" Y/N says as he stomps on the demon's head multiple times before it would turn to nothing releasing all his anger out.

Y/N breathes deeply exhausted, as his adrenaline calms down, now flooded by how his injuries hissed in pain. Gritting his teeth, he fell to his knees as his hands clutches the dirt, trying to control his breathing to ease the pain. It took him a while for his body to feel better, still feeling the stinging pain but enough for him to ignore it.

"Fucking shit! That is the worst idea I ever had in my life!" he shouted to no one but to himself. Taking a mental note to control his emotions in battle.

He lifts himself up, grabs his sword, and sheathed it, then started limping his way back to the wisteria house to get help and heal his wounds.
