After the battle of the Asakusa incident, Tanjiro returned back to Lady Tamayo's house as he yelled "Tamayo-san! Yushiro-san!" "We are here, down the basement." Yelled Tamayo as Tanjiro follows to where she is, in the Basement. He saw as both are safe. "Sorry to keep you waiting." Says Tanjiro as Tamayo says "it's fine Tanjiro, and since Our location has been blown we will relocate eventually..so about my our discussion, the demon moon blood, the mark's Cure and your sister's blood." She showed the bottle of nezuko's blood and Tanjiro smiles and replied "i will help you as long as your helping me. We are on the same page after all..and Thank you, it seems that Yorrichi did the right thing since he saw something in you when he first met you" Tamayo smiled and Yushiro says "Tanjiro, you better not be close to her." "She's 500 years old and im 15, So don't get paranoid for that." Replied Tanjiro and Yushiro could not say anything since he's right. "Fair point, now i shall give you some equipment for what you need to collect blood." Said Yushiro and Tanjiro replied "Of course!"

6 days have passed, now at Noon as Tanjiro left the city, Walking on the street as Tanjiro's crow flies to his shoulder and says "Next mission Make your way to the north east." Tanjiro replied "Okay then...in the meantime why not we bond for a while, shall we?" Asked Tanjiro as the crow says "Caw! Don't see why not." While Tanjiro Bonded with his crow who's name is Matsuemon, he's quite intelligent yet he seems to have a large ego. And as they bonded, Matsuemon was surprised to learn Tanjiro is wielding Sun breathing and wielding the Sword of the first breath user. He seems excited and can't wait to brag this to others, and Tanjiro seems to like how much ego he has.

Until the sun started to set as they both Ended up Hearing yelling, they saw how a man is yelling at a child, the one with turquoise blue eyes, with long hair with turquoise blue tips, his uniform seemed to be a haori at the same time, as the man yelled "Are you making Fun of me? First you ask me about demons which they don't exist and then you all of a sudden forget what to ask and changed the subject of asking your own name?! Are you seriously wasting my time in asking such nonsense!?" "Well i was, wait who are you again?" Asked the boy, as Tanjiro remembers him from the final selection 'its him from the final Selection, he probably needs help.' Tanjiro rushed to the man, pulled him away from the boy "What do you think your doing harassing a child here?" "Oi, you stay out of this" says the man who turned out to be drunk and Tanjiro had no choice but to neckchop him since he knows there is no way he wants to deal with this. He knocked him unconscious and puts him Infront of his house.

Meanwhile 2 crows cawing each other while Tanjiro faces to the boy and says "you okay? Did he hurt you?" Asked Tanjiro and the boy who's eyes are nothing but empty and says "yes and no, but i didn't need your help, i was going to neckchop him as well...wait who are you?" "My name is Kamado Tanjiro" says Tanjiro as the boy says "Oh well, My name is Tokito Muichiro, but I'll forget it anyway." Tanjiro got confused of what he's saying "you sound like your on amnesia, are you?" "In a sense yeah, so who knows.." says Muichiro with Tanjiro while smiling saying "well, i hope your memories return, in the meantime we can get to know each other." "Like i said before, I'll forget it anyway...but sure." Says Muichiro until "Caw! CAW! Tanjiro! Muichiro! head to the mountains in the front, the demon is awakening! Caw!" Says Matsuemon as Muichiro quickly runs off and Tanjiro got surprised as he followed him and managed to keep with him, running at matching speed, "so, what's the plan there?" Asked Tanjiro and Muichiro replied "not sure, but we'll get there." As he runs even further as Tanjiro as well.

Both arrived to where they're heading as they saw a large demon with 10 long arms and multiple tree branches around its body. "Oi, demon hunters, here to be my food, or hear to get in my way?!" Yelled the demon as it starts attacking, having Both Tanjiro and Muichiro jumping and splitting apart, "demon hunters splitting apart is the best thing" Tanjiro pulls his Burning sword out as he manages to dash and slash one of its large hand. The demon is screaming in pain "owww, Hot Hot, it burns!!" As Muichiro makes his move

Mist Breathing: Fifth form, Sea of clouds and Haze.

Muichiro dashes in a zigzag motion, slicing of its 4 arms from the shoulder and the legs off, leaving the demon to trip to the ground to his front but it immediately regenerated and started to get up "You Brat!" 'I have to make sure it stays in one place, and i know just how to do it!' thought Tanjiro as he makes his move.

Hinokami Kagura: Sunflower Thrust.

Tanjiro Dashes to the demon's right side chest and stabs it as the demon starts Burning it in pain and screaming, not being able to move because of the burn "ahhhhh! It burns, why is it burning me!?" "Muichiro! Nows your cue, Slice it's Head off!" Yelled Tanjiro as Muichiro dashes to the demon and he ended up Decapitating the demon. The demon faded to Ash as they both watched it die. "Seeing a demon this Large and its weak." Says Muichiro "at least we killed the demon." Says Tanjiro and Muichiro lay eyes on Tanjiro's sword being on fire and asked "why is your sword on fire?" Tanjiro then turns it off and sheathing the sword inside "oh, it's how my sword is, It's a long story." "Well, even if you tell me, I'll forget it anyway." Says Muichiro and Tanjiro's crow comes in and says "Tanjiro, Muichiro, make your way to north west. Caw!" As both arrived to a crest with the gate written and called "Westeria Family crest." "Caw! Rest, rest, You had a rough week! Caw!"

An old woman shows up "i assume you must be demon slayers, Come in" Both entered in, they entered a room to see 2 night clothing with the lady on the floor "your clothing for comfortable rest." They changed until they went to another room with 2 tables on the floor with food and the old Lady on the floor "your dinner is ready." They both started Eating, As till they finished their food, they found themselves in another room with 2 futons and the old lady on the floor saying "your futons is ready."

Later on both Tanjiro and Muichiro laying on their beds while a lamp turned on, "who would have thought that most of our first few missions we had, and we received no injury." Says Muichiro and Tanjiro say "My first mission was okay, my 2nd was chaos for complicated reasons and the 3rd one was like a piece of cake for us." "Your 2nd mission, how was it Chaos?" Asked Muichiro and Tanjiro in a hesitant look and saying "even if I tell you, you'll forget it anyway." "Fair enough, aside from that i didn't really need your help on that mission. Yet you helped me out anyway." Tanjiro replied "Well, Helping others eventually becomes good for me." Muichiro in deep thoughts until his eyes started shining as he gets up, sitting on his futon and faces Tanjiro and asks "what did you say? What was that you said?" Tanjiro faces him while laying down "Helping others eventually becomes good for me." Muichiro lays back on his futon and watches the ceiling and Tanjiro seemed curious he could pick up a scent of confusion "hmmmm... I don't care if I'll forget anything about what you'll say, but i wanna know. Why is your sword on fire, and what breathing technique are you using to address it as Hinokami Kagura?" "Well, I'm wielding Sun Breathing and my blade is Crimson red while it absorbed Too much sunlight." Replied Tanjiro and Muichiro seemed confused as he says "Sun Breathing? How did you get that?" Asked Muichiro and Tanjiro answered "well..."

As moments passed both are sitting on their futons and Muichiro seemed curious now "is it so? You have the sword and the breathing technique, passed down by the first breath user and it's been with your family for years.. quite odd, i was told that I'm the descendant of the First breath user." "is it so? But Yoriichi-san had no descendant since he already lost his wife and unborn child." Says Tanjiro and Muichiro was confused to hear it, "if I'm not his descendant then who am i, just some simple ordinary child?" Says Muichiro as he faces him and Tanjiro says "Well, I didn't bother checking up on Yoriichi-san history with his family. I better Check it now," as he takes out Yorrichi's Journal as he started looking around the pages "You better, i would want to know as much as you want to, i honestly don't call myself special as much as my crow is going to end up bragging to others about me as a Prodigy." says Muichiro as he lays down on his futon and faces to the ceiling until a few minutes later "No, it can't be..." Says Tanjiro as he looked through it as Muichiro asked "what is it?" "You are infact a distant relative of the first breath user." Says Tanjiro as he looked traumatised "so why is it shocking for you?" Asked Muichiro as Tanjiro in hesitant and says "You are a descendant of Yoriichi's Twin Brother, Tsugiikuni Michikatsu. The 2nd Breath user, also known as...Upper moon 1." Muichiro gets up from his futon in pure shock, staring at tanjiro as he tried to Deny it "me? A descendant of...an Upper moon?! Let alone the number 1?! Are you saying a Pillar from the sengoku era turned Traitor against us? You have to be lying!" Muichiro yelled as he saw Tanjiro's eyes and noticed he's not lying "How is that possible?!" Asked Muichiro as he never felt fear like this.

Tanjiro breaths and begin to explain "Your ancestor is a powerful Swordsmen, but not a good person since human life, he was someone who was always jealous of his brother, and yoriichi doesn't get to notice it. He abandoned your family, joining the corps to become the strongest samurai in the world, He attempted to weild Sun breathing, but he couldn't and he created Moon breathing. No Matter How many forms, he still couldn't surpass his brother. As a result his jealousy has lead to joining in kibutsuji's side. As such, not only did yoriichi failed to defeat kibutsuji, but his brother betraying the corps, he kill, one of the leaders in that era, killed 4 pillars and all sun breathing users out there, it has resulted in his excile. Yorrichi ended up informing your family of what he did, as a result the Tsugiikuni name died out to the name 'Tokito' and after that. He stayed with my ancestor and passed down everything to us." Said Tanjiro and Muichiro could not believe in his eyes, "and now that i see your Sword's color, it make sense." "Of what?" Asked Muichiro and Tanjiro says "well, to put this simple, normally a mist breath user would have Pale White as their sword's color, but your sword has a different colour which means mist breathing isn't certainly for you." "Are you saying, i could wield a breathing technique which is being used by a demon?" Asked Muichiro and Tanjiro goes through his pages and saw that Yoriichi noted down the knowledge of moon breathing technique and said "Well in a sense, your sword Shines like a moon as much as you do, so yeah." Muichiro seemed to be having mixed thoughts as right now. Tanjiro showed him the information of moon breathing "just to let you know im not forcing you to wield it, it's your choice but I'm warning you, if you wield a breathing technique which isn't suitable for you, your sword could break at random times." Muichiro takes the journal and says "I'll take a look at it, to see it myself." "Sure thing." Said Tanjiro as Muichiro starts reading it all, in his need to learn something about his bloodline.

Later on, 3 weeks have passed as Matsuemon flies to Tanjiro from the door "Make your way in the butterfly mansion, You'll be staying there while your not on any missions. In the meantime, you may wish to train while your at it. Caw!" "Very well then, lets go Muichiro... Muichiro?" Asked Tanjiro as he saw him sitting outside on the floor of the house as he says "Tanjiro, you think I'll be able pull this off? Me as a moon breathing user?" "Why do you ask?" Asked Tanjiro and Muichiro gives the journal back, "i tried wielding it and it feels much better then mist breathing, I'll see how well it gets during training." "I see, shall we get going?" Asked Tanjiro and Muichiro stands up and smiling at him warmly and says "...yeah, let's go...and train harder as we can." And Tanjiro smiling and he nodded.
