5 days passed since the selection exam, In Mount Sagiri where It's morning and with Tanjiro reading the books saying "So, once you become a demon slayer, the nichirin blade will have it's color?"
"Correct." replied Sakonji
"Which means." Tanjiro unsheathed his sword as the colour of the sword ends up having a pitch black color in it's front dept while the back dept having light gray and The Kanji saying Destruction.
Note: The same blade design from the yorrichi type 0.
"Black.." Sakonji who he seemed curious with Nezuko being concerned and asked "Is it a bad omen?"
"Nope, it's a thing no such. It's unusual to have a black sword." says Sakonji
"As unusual for you since Black Swords is meant for sun breathing users." replied Tanjiro
"is it so?" Asked Sakonji and Tanjiro answered "it is, Yorrichi-san also had a black sword as well. It's said that Black swords absorbs sunlight the most, and since my family has been using it, it has been absorbing sunlight for 500 years. So there is a chance the sword will turn Red eventually."
"This is what legends say, the steel from the senkogu era is good quality, the more it absorbs sunlight...the hotter the blade gets." says Sakonji "but i never knew black swords are meant for sun breathing users." Until suddenly the blade turned Crimson red with the back dept turning dark red and the front crimson red and at the same time, it's catching on fire. "I guess the blade is already hot then." Says Sakonji and Tanjiro was surprised to see a red blade let alone burning right now.
A crow then flies and Enters inside the shack and yells "Caww! Caww! Kamado Tanjiro, here are your mission assignments."
"Eehh? a talking crow?" asked Nezuko in surprised as Tanjiro proceeds to listen "Make your way to north east, there are demons in mysterious abandoned house, Make your way there. This is your first mission. Cawww!" says the crow as Tanjiro gets up.
Hours later, Tanjiro starts wearing his uniform, with his green checkered haori, with his sword on his waist. "well, i should be going now."
"oni-chan, please don't get yourself in trouble." says Nezuko in worry while "I'll do my best."
"save journey's Tanjiro." says Sakonji "and i must warn you, Even though you have a red blade, still those with black swords don't last long, but since you've assured me that it's for sun breath users makes more sense now."
"i know, demons fears it for a reason, well then i should be going now." says Tanjiro as he waves them good bye.
As time passes on with Tanjiro arriving to his location, A large abandoned temple and he's already picking it's scent. He enters inside as he unsheathed his burning sword, as he hears sounds of running and crawling, The Demon appears from behind and charges tanjiro, as an attempt to slash tanjiro with its claws but all of a sudden, he went through tanjiro and he suddenly disappeared.
Hinokami Kagura: Fake Rainbow
The Demon got confused as tanjiro comes from behind and immediately beheads the demon off. Tanjiro kept his guard up since he can smell more demons around here. He saw how 6 more were charging towards him.
Hinokami Kagura: clear blue sky
but tanjiro was able to deflect their attacks from their claws and easily slicing them off and Managed to behead 3 of them off. As he kept his guard up, him deflecting and slashing them constantly till eventually he decapitated them all. He could smell that there aren't any demon sightings anymore. As he wondered around and found that they are nothing but dead bodies so he spends his whole day alone burying them and praying.
His Crow flies and landed to his shoulder "Next stop, City of Asakusa, Rumors about demons lurking there."
"next mission already?" asked Tanjiro
"Next mission already.." replied the Crow as he raises his wing up.
"so let's see it then." says Tanjiro as he started leaving. As hours have passed and Tanjiro has entered in, a whole crowded City. Leaving him to be utterly confused and zoned out.
'This place is too big, i never been to a city in my life and it's already giving me a headache.' Thought Tanjiro as he wonders around only to find a small stop of Ramen, He wents off to buy and eat it. "one Ramen please." he asked it as the chef gives it to him. Sooner or Later Tanjiro finished it and managed to pay for it and he's feeling better now. 'This will be complicated then I-' Thought Tanjiro but all of a sudden, he begins to pick up something. He Runs off all the way to an empty street surrounded by houses, though Tanjiro couldn't see it since the streets are empty and dark, he could see only someone who's all alone walking ahead. 'That scent, which was left at my House! And now im picking it again!'
Flashback plays with Tanjiro reading books as he says "So there's only one and only demon who can turn a human into a demon, the one who's the progenitor of all Demons. Who lived for 1000 of years."
"Correct, More importantly, He's your target. The one who attacked your family." replied Sakonji "and You know that demon's name?"
"Yes." says Tanjiro
"And I remember his description really well..." says Nezuko who she remembers him when she was attacked.
Flashback ended by with Tanjiro finally closing to the man and he finally lays eyes on him. The man then turned around to Tanjiro in confusion after hearing foot steps of running, Tanjiro stops running and stares at him in a cold look, With Nezuko's voice running in Tanjiro's head as memories, of him remembering 'a young man with curly black hair and bright orange eyes, in his late twenties. He has pale skin on his face, he can shift his small nails into distinct long blue nails. He wears a white fedora with a bow, and an elaborate matching suit and his irises are cat-like appearance.' says Nezuko in Tanjiro's flashing memory voices as with him seeing the same exact description, Tanjiro yelling "Kibutsuji Muzan!" With Tanjiro being far away from him The man name Muzan's eyes opened wide as Tanjiro pulls his Burning sword out and immediately dashes at him.
Hinokami Kagura, Dance
Tanjiro dashed and Slash at him, burning Muzan having him to backoff and trips back wards as he says "No, it's impossible."
Clear blue sky
Tanjiro immediately performing a 360 spin in attempt to slice him in half until he suddenly Exploded into 1500 pieces everywhere Leaving Tanjiro in shock that he dodged it, "I Smell fear in you!" says Tanjiro in a cold Tone
Burning bones summer Sun
Tanjiro spiraling and slashing everywhere and managed to target and burn 27 pieces into ashes, He saw how the pieces are flying away as Tanjiro in his cold look, Decided to chase them. By jumping around top of each houses while the pieces are flying together like a group of bees. "Kibutsuji Muzan! I promise you won't escape me!" Yelled Tanjiro as He dashed and Jumped to the flying pieces.
Hinokami Kagura: Solar Heat Haze
he jumps to the pieces and slashes and destroyed 14 more pieces. As they all fly down to a random empty street, and them flying across it as Tanjiro Follows, The chase goes on as until the pieces rushed and breaking through a small sewer trap door, and enters in, escaping Tanjiro fully. 'Dang it, it's too small for me to enter in.' Tanjiro stands infront of it and yelling "Dont think you'll hide for this long! I promise you, you won't escape me! I will follow you to the ends of hell, and my Burning red Blade will be last pain you'll ever get. I Will never Forgive you for what you've done! Kibutsuji!" yelled Tanjiro as he was furious that he escaped.
Flashback plays of him reading books while Talking to Sakonji, "he is all of our target, but it's never an easy task. Even if you drove him into Corner, we will eventually escape by dividing himself into 1500 pieces."
"Sounds unfortunately hard, but never impossible." says Sakonji
Flashback ended and as Tanjiro breathing in anger until he felt something as he aimed his burning sword towards where its coming from and saw 2 people, and women and someone in hid late twenties, As the Woman says "even if you nearly drove him down, he would just escape anyway."
"The scent, you 2 are." says Tanjiro
"indeed we are demons, but I'm very much a doctor other than a predator... I'm also chasing down the one named Kibutsuji Muzan." says the Women and Tanjiro opening his eyes wide as he thought 'i smell no lie, nor any bad intentions. only truth, Unless.'
Flashback continues as Tanjiro says "Not impossible, since there is a way to prevent that."
"is there?" asked Nezuko
"there's a Demon who escaped Kibutsuji's control, who wanted him dead, Yoriichi-san noticed her wishes after seeing her eyes and he spared her life for it. It is said that she's a doctor, who would do anything to help us defeat Kibutsuji...That demon's name is Tamayo." says Tanjiro as Flashback ended With Tanjiro turning off the fire from his blade and asked "You...You must be her, The one who Tsugiikuni Yoriichi Spared...Tamayo, is the name is it?"
The Women got surprised as the man asked "Ehhhh? How do you Know her Name!?" in Anger as the Women says "Yushiro, stand down for a second." "Yes!"
"You are correct, Tamayo is indeed my name...You seem to be familiar with Yorrichi, are you?" asked Tamayo
"It's a long story.." replied Tanjiro
"Then you may come with us, this is no place for us discuss." says Tamayo.
Later on, the pieces around the sewers as the pieces flew all the way to a clear space, and put itself back in physical shape, except he could not regenerate properly. Muzan seems to be very Pale then usual as he's panting as saw how he's burned, since Tanjiro destroyed alot of his pieces, as he managed to regenerate but his scars becoming visible. He Snaps his Fingers, Summoning 2 demons behind him, kneeling before him. One with short long hair and the other with shortest hair. "Bring me the head of the Demon slayer who wears Hanafuda Earings...Understood?" said muzan in a very pale tone
"as you wish." The demons vanished While Muzan trembling and Thought 'Those earrings, That Sword.' him beginning to have flashbacks of Tanjiro attacking him only for Tanjiro's image, to warp into Yoriichi's appearance back and forth, glitching over and over. As he climbed up to a sewer entrance and exits there and found himself in an street, next to a tall building, He faced up as he busted through the door and enters in.
Meanwhile with Tanjiro and the others. He saw how they are heading to a wall "hurry, before anyone else see us." says yushiro as they goes through a wall, tanjiro got surprised as he looks around and gets inside fast. As they are in a living room, sitting on the floor with Tanjiro and his sword lying on the floor saying "So before i explain my reasoning in knowing you, i must know something about your current life after you were spared. As a demon you are, I'm curious."
"you may perhaps wonder how im still alive without harming humans? As you know, if a demon loses it's energy and never got to have blood. they would go berserk that not even there minds can be in check and ends up looking for prey. And for us, it's simple me and Yuishiro drink blood in a way, as a doctor i ask my patients for blood as a tip." Says Tamayo
"I see, i smell truth, that's good to know.' says Tanjiro
"And here and now, i have Yuishiro, my assistant since he's my Creation as a demon." Says Tamayo who she says it while being proud as "Is it so? i thought only Kibutsuji can create numbers of them." says Tanjiro in confusion and tamayo replied "That is correct, since Kibutsuji's abilities is Bio-Kinenis, he can create them. While me as a doctor i have done some research which took me 200 years to have the ability to create a demon."
"200 years? you're 500 years old and it took this long. You must have experience in creating medicines and many things." says Tanjiro
"It's True, Lady Tamayo is the smartest one as a doctor... although i must ask, you knew her age since you knew her name too..how do you know her, does the corps know about her?" asked Yushiro as Tanjiro says "I don't know if the corps knows or not since i just joined in and here and now it's my second mission." says Tanjiro while he pointed to his ear "and for me it's as simple as tamayo will be able to understand, Recognise these earrings?" as he pointed to them as Tamayo Nodded and said "Of course, i very much do, and i recognise that sword as well, The same sword which burned Kibutsuji a long time ago. But this time, i sense something in this blade which seems more Hotter then last time i saw it to watch it being on fire, how is it you got it? your not even his descendant."
"Well, this spent a whole 500 years of getting absorbed by sunlight which is why it's hot enough to be on fire, And Yoriichi passed them to my family after getting exiled from the corps, The earings, the sword, the breathing technique, knowledge of the sengoku era and his life. That's how i know you as a rebel." replied Tanjiro
"makes more sense now...So it's settled that you and i are trust worthy for each other, So on to our real discussion, since we have the same goal i would like have you to assist me while your out there on missions, for us to make sure Kibutsuji doesn't escape i must create a drug, Capable of weakening him, but for that to happen I'm going to need you collect blood from specific demons, ones who has a thick amount of kibutsuji's blood. And Since you are new into the corps, this here you must know, the blood you'll have to collect is from the ones called The 12 demonic Moons."
"Demonic moons?" asked Tanjiro
