I don't own Dragon Ball, Kimetsu No Yaiba and Doctor who. Dragon ball is owned by Akira Toriyama and Kimetsu No Yaiba is owned by Koyoharu Gotouge.
Last time the Doctors have cured Tanjiro turning him back into a human. The doctors had to Explain what happened to three of the pillars and Tanjiro, Nezuko and Goku have started their training towards becoming Demon slayers.
Chapter 3: Muzan Kibutsuji plan:
Muzan Kibutsuji has called an meeting with all 12 demon moons. He says how did some one get blood samples from all twelve of you with ease. But sir all we heard was a shss noise and that was it is was so quick. Muzan went it couldn't have been that guy I thought against when I killed the Kamado. Muzan also says I heard at a demon was turned back into a human and the thing that annoys me is that the boy with hanafuda earrings was the one turned back into a human. Upper moon demon one says hanafuda earrings? That's why you want him dead or a dead because he's a breath of the sun user? Muzan says correct. But I have a mission for some of the lower demon moons and that mission is to capture the both the man and woman who calls themselves the Doctor. Why? asked a lower moon 3. Muzan says they are the ones who turned the boy back into a human so I want them to try and find away for me to Conquer the sun.
Back with Tanjiro, Nezuko, Goku, Urokodaki and the Doctors:
Goku gets hit by all of the traps but he did break the log traps and few the logs away. Goku got back way quicker than Tanjiro and Nezuko did. Urokodaki says Goku I also accept you as my Student.
Tanjiro and Nezuko both trained a lot they even got punished alot when they did the stances for the water breathing forms wrong. Goku got then correct straight away after watching Tanjiro and Nezuko finally get them right. Tanjiro and Nezuko both noticed that the air is thinner. Goku doesn't notice. Urokodaki says concentrated breathing strengthens the body. Tanjiro and Nezuko got punished for doing it wrong. Urokodaki is however impressed with Goku who gets it right. Goku says I already know how to do concentrated breathing since I am a martial artist. Urokodaki goes okay them so I can start teaching you the 10 water breathing forms. Goku learns then all in a few days and successfully cut the boulder in one go. Goku goes to the final selection.
Goku says thanks to your training I can now see auras of every living thing. That the final selection Goku doesn't meet the Hand demon. Goku does however cause everyone to survive the final selection. Goku got this uniform and has to wait 15 days for this sword. Goku instant transmissions back to Urokodaki. Urokodaki is happy that Goku made it back. Goku says the final selection was to easy and I managed to keep everyone else there alive too. How is Tanjiro's and Nezuko's training coming along. There are getting on just fine I think they are currently on the bounder.
Goku goes hey Tanjiro and Nezuko I am going to teach you both the Kaio-ken technique. Six months pass and Tanjiro and Nezuko have successfully learnt the Kaio-ken but haven't learnt how to the water breathing forms correctly. I boy wearing a task goes to Tanjiro saying your not a man. What have you been doing for this last 1.5 years same with your sister she's not a woman yet. After beating them both down. I leave the rest to you. A young girl appears.
Goku is out on missions and the Doctors are arguing. Look I don't want to wait like another one to 1.5 years for the Tardis to work again and we still need to separate our Tardises.
Goku enters a village and at night starts fighting a swamp demon that has spilt into four. The demon hides in his swamp Goku uses instant transmission to enter the swamp which confuses the demon. They demon goes how did he enter my swamp without an opening anyway he is a fool. Goku noticed that the demons are circling him in the swamp but Goku goes Total concentration Water Breathing sixth form Whirlpool and kills all four demons with the one attack Goku uses instant transmission to get out of the swamp before the swamp disappeared for good.
One night upper moon demon three Akaza finds where the Doctors are hiding and tries to kidnap them. The 13th Doctor managed to get away but the 10th Doctor is caught and taken to Muzan. The 13th Doctor says this is bad really bad. I must try and save my pass self or get Goku to do it for me.
Tanjiro and Nezuko find out that the girl helping them train is called Makako and that the boy who beaten them is called Sabito. Goku appears to checking on them. Nezuko says I dreamt that I read a journal about the training and I didn't think that it was actually this hard and bad. Goku asks how is the training coming along? Just fine! Said Tanjiro. Goku them says you both have been training for two years now. And who are these two? Nezuko says these two are called Sabito and Makako and they are helping us train. Goku went nice to meet you both. Okay Sabito and Makako I want to talk to you both in private.
Goku chats if Sabito and Makako in private. Goku says I know your both spirits. Sabito says how do you know that? Goku replies saying I had been trained my some spirits before in an other Dimension that the Doctor helped me escape from. But he had a different face compared to these two versions of him/her.
The 13th Doctor appears and says Goku I need your help a demon kidnapped my past self. Goku goes okay I be right back. Goku uses instant transmission straight to the 10th Doctor. Muzan sees this and gets angry. Goku reappears back at the 13th Doctor with the 10th Doctor. 10th Doctor says thanks for the save Goku. Goku says no problem Doc.
Tanjiro and Nezuko have finally cut their boulders. Tanjiro thought at he cut Sabito's mask when he smelled the thread. Nezuko thought she cut Makako masks when she was the thread with her fog of colour. But they both actually cut their bounders. Urokodaki comes up to them and says I didn't plan on sending you both to the Final selection because I didn't want to see any more children die. I know that Goku made it back but he is a full grown man and a very quick learner.
The crows says to Goku next up, Asakusa Tokyo! Rumours of a demon lurking there! Goku goes straight to Asakusa Tokyo with instant transmission. Goku recognises Muzan's ki right off the back. Goku finds him and is shocked to see him pretending to me human. Muzan lies saying to the woman and girl that he never seen Goku before. Muzan thinks (I somehow need to get rid of this guy but he is now a demon slayer dammit). Muzan extends his nails and hits a random person's neck turning that person into a Demon. The newly turned person bites this wife shoulder Goku stops the new demon by pinning it. Muzan says don't look to the little girl and they start walking away. Muzan though that he lost Goku but he didn't know at Goku can be in two places at once by using Tien's multiform technique even know it halved Goku's power it doesn't matter.
Goku shouts you think you can get away and escape me? Please I will find you and kill you out of the publics site. Muzan is angered. Muzan tells the woman and kid that he is going to report what he saw to the police. After they left Muzan went down an ally which is empty. He clicks his finger and two demons show up.
Goku goes I can't let this guy go officer I am the only one who can pin him. A flowery pattern appears Goku thinks it's an attack an woman appears. Goku says I know you and that young looking lad are demons I can tell by your aura and ki. Goku them says well thanks for the hell I guess she went you can come with us. Goku says alright then has long I can have something to eat because I am so hungry!
All of them have walked through a fence Goku isn't surprised at all. The woman introduces herself and the boy to Goku. She says I am Tamayo and this is Yushiro. Goku says I am Son Goku and I am currently the third highest rank in the Demon Slayer Corps and I am not that far from getting promoted. Goku says your both lucky at I can tell that you are both good demons. But I do sense some regret from you Tamayo. She says what do you mean? Goku says I am guessing you killed people after you first turned!
Tamayo says your right Goku. Goku says okay so about the spell hiding you and the place. It's just that you can't hide your life energy. Hold on I be right back I sense two high negative power levels coming this way and I think that they are demons that Kibutsuji have sent after me. I be right back after I kill them. Goku disappeared using instant transmission. He appeared in front of the demons that are looking for him.
The demon says thanks for making easy towards finding and killing you. Goku says give up you both don't stand a chance against me. Goku pulls out his sword which is just yellow coloured like Super Saiyan. One demon says how do you think your going to take on two of the twelve demon moons. Goku says I can destroy the solar system like 2.5 times you know. I was the one who accidentally shook earth twice.
Makako goes Sabito? Do you think... Tanjiro and Nezuko can really do it? Sabito says I don't know. But no amount of effort is too much. And you know that right? Plus thanks to Goku Tanjiro and Nezuko can both use the kaio-ken technique but only for a short time at times 1.5. But I also don't know how Goku didn't come across that demon when he did the final selection.
At the final selection Tanjiro and Nezuko both end up against the hand demon that Goku somehow missed when he was there. The demon goes tell me foxes right now what Meiji Emperor sits upon the Throne? Nezuko answers the Imperial family is Taisho! The demon goes I have been here so long that Dynasties have risen and fallen again and again all while I've been trapped here!
Damn Urokodaki, damn Urokodaki damn him! Damn Urokodaki. Tanjiro you know Urokodaki? Oh I know him! Urokodaki was the one who captured me! I will never forget it! It's been 47 torturous years! Back then he was still a demon slayer in the Edo period the Keio era!
Tanjiro and Nezuko both though (demon hunter Edo period?!). The boy Tanjiro and Nezuko saved says no way you're lying no demon has lived that long, lies. They only put demons up here that have eaten two or three people and get killed during the selection also demons eat each other too! The demon says I have eaten like 50 of you brats.
Flashback to Urokodaki sharing information with Tanjiro and Nezuko remember a demon's strength comes from the number of people it has consumed. So if it eats many more people it gets stronger? That's right they grow stronger and some physically change, gaining unnatural powers. Even know Goku has some unnatural powers and he's not a demon and remember the Doctors aren't demons too. Plus Tanjiro if your nose gets stronger you'll be able to tell how many people a demon has eaten. While I think Goku who can sense life energy and now aura might already be able to tell but he's already on missions. Nezuko might also be able to tell when her ability to see colours in a fog improves enough.
The hand demon goes 12, 13 and both of you've are numbers 14 and 15. Tanjiro asks what are you talking about? That's how many of Urokodaki's students I have eaten! I've decided to kill all of his students. Nezuko remembers from Tanjiro's Journal she read in her pass life that Tanjiro defeated a Hand demon at the final selection. Nezuko thinks (so this is the hand demon hmm).
The demon says yes indeed! Thirteen of Urokodaki's students, but above all... Two of them I'll never forget. He had a colourful jacket, and was strongest by far. He had peach-coloured hair and a scar my his mouth. The other was a girl brat whose kimono was covered in flowers. She was small and not so strong but she was very agile. Tanjiro thinks (how could this demon have killed them? They trained me and Nezuko!). Nezuko thinks (how did I forget that I read that part of my brothers journal.).
The demon says I recognise you by those fox masks. I know the grain of those masks that Urokodaki carves. They're carved the same way as the Tengu mask he wore. Did he call it a "warding mask"? I ate them all because of the masks they wore. They're all inside my stomach. It's like Urokodaki fed them to me! Heh, Heh, heh, heh, heh, heh. The girl brat wept and grew angry when I told her that. Heh, Heh, Heh, Heh. Soon her movements got shaky. Heh, Heh, Heh! Then I ripped off her arms and legs!
Nezuko says Tanjiro please keep calm and think. Tanjiro says thanks Nezuko. Nezuko says by the demon you missed one of Urokodaki's students the Final Selection before this one last year. The demon goes really dammit. Tanjiro says your lucky to still be alive because if he came across you last year you wouldn't be here. The demon says why do you say that? Nezuko says because that guy shook the planet twice over two years ago. The demon tries to attack Tanjiro and Nezuko and they both dodged. Tanjiro and Nezuko both looked at each other and nodded. They both charge the demon at the same time and they both go Kaio-ken times two. The demon goes what is this red stuff coming from both of them they are both moving twice has fast. Tanjiro and Nezuko both go Total Concentration. Water Breathing!
The demon goes dammit they're both in striking range! But my neck is hard and impervious! Even the peach hair couldn't cut it. When they both fail to cut my neck, I'll grab their heads and crush them just like I did to the other one! Tanjiro and Nezuko both see the thread. Makako says is it possible that Tanjiro and Nezuko will lose too? That thing's neck is so hard. Sabito says they may lose or win or one lives and the other dies. But one thing is for certain... The boulders that Tanjiro and Nezuko cut was bigger and harder than anyone had ever cut before!
Both Tanjiro and Nezuko go first form water surface slash! Flash the mutant demon! This sound they made at that moment was the same sound that came from that other guy back then, like sound echoing against the rolling wind. The demon goes Urokodaki! This is because both Tanjiro and Nezuko are in the same striking post like Urokodaki back then. Tanjiro and Nezuko both have successfully cut the hnad demon's head off. The demon says damn, damn, damn, damn! I'm going to die! My body is gradually falling apart, I'm already too late to stop it. In the end they'll gaze upon me with eyes that are as if they'll both looking at filth. The type of eyes that are full of disdain. Dammit I'm so afraid to close my eyes. But this body won't allow me to turn my head. I can't believe the last scene I look upon before my death are the faces of these two demon hunters. Why do you both have that expression on your face? The demon hears big brother, I'm alone in the dark I'm so scared. Big brother hold my hand like you always do. Why did I devour my brother? Eh? Who is this brother I'm thinking about?
Tanjiro goes a scent of sorrow. Tanjiro and Nezuko both hold the dieing demon's hand. The demon head is crying. Tanjiro and Nezuko both pray God, please allow this person to never become a Demon again when he reincarnates. The demon has versions. Big brother. Big brother, big brother grab my hand. Alright, alright, you're always such a scadey-cat.
Tanjiro and Nezuko both go Sabito, Makako, we won. You guys can be at ease now. The other children that were killed will also return just as was promised. Even though they are only sprits now. Return back to by their beloved Urokodaki sensei's side. Back to their home narrow mist mountain. If we die our spirits will return to where Urokodaki sensei are.
Goku is battling two demons lower moon demons two and three. Goku easily with no effort at all kills both demons. Muzan gets word that lower moons demons two and three have been easily killed with no effort at all. Muzan doesn't have a clue towards how do get rid of Goku. Goku accidentally forgets about returning to Tamayo and Yushiro.
7 days later morning:
Tanjiro and Nezuko have both survived and made it back. They hear welcome back, congratulations being safe and sound is better than anything else. Tanjiro thinks (there are only five people left? There were 20 or so people before. That guy we saved isn't here too. Another demon must have got him.). Nezuko thinks (I don't want to tell big brother this but I know there's six people left if I remember correctly.).
Tanjiro and Nezuko look at a boy that says will die five times over even if we survived we'll still die in the end.
Another boy goes eh? What do I do? What about the Blade?
The boy and girl says you must first pay the cost of the uniform, then you must get your body measured and have your rank engraved. One of the boys asked what about the blade? Today, you will each choose a chunk of Tamahagane alloy. Your blade will be completed within 10 to 15 days. Tanjiro says 10 to 15 days hmm we could possibly get a little bit more training from Goku. Nezuko agrees with Tanjiro on getting abit more training from Goku. There are ten ranks in total 1st, 2nd, 3rd, 4th, 5th, 6th, 7th, 8th, 9th and the 10th, you are now lowest 10th level. Also from now on kasusagarasu will be following you all.
Kasusagarasu is a crow that primarily used for communication. One of the boys went I don't care about some dumb crow! What I want is the blade right now! The blade of the demon hunters! The "blade of colour change"! Nezuko sees her brother Tanjiro grab hold of the boys arm going let go of her this instant! If you don't I'll break your arm. Huh? Who are you? You can try if you dare! Tanjiro breaths and almost breaks his arm. Are you done? If so please go over there and choose the alloy that will create your blade.
The alloy for the blade that will be used to destroy demons and protect yourself will be chosen personally by each of you. The blonde boys says I'll probably die really quickly. Back at a building a man with a crow says is that so there are six people remaining they seem to be excellent, my swordsmen have increased... I wonder what kind of swordsmen they all are.
Meanwhile with the Doctors:
10th Doctor says well other me at least we have managed to reduce the Tardis's remaining recharge time from a whole year to half a year. 13th Doctor says well the good part is that also allows us to be able to take Goku home half a year earlier. Goku appears and says hey doctors how are you both doing. 10th Doctor says ah Goku we have managed to shorten the Tardis's recharge time by half a year. Goku says that's great news. I also have double good news. 13th Doctor says what's the news. Goku says I have been promoted to pillar level but I can't become a pillar until the current water pillar dies or retires but I still have to go to the meetings. And the other good news is that Tanjiro and Nezuko have both passed the final selection and are now official demon hunters. Both Doctors say that's great use thanks for informing us. Goku says I now have to go to a pillar meeting I see you soon.
TBC
Author notes:
Well Goku has already killed the swamp demon and has also killed lower moons two and three. He has also met Tamayo and Yushiro but forgot to return to them. He will return to them later on.
Both of the Doctors have shorten the time for the Tardis to recharge by half a year.
Oh and working on two stories when planning a third one, the five way crossover.
Oh yeah Goku's sword is only yellow in his one like Super Saiyan because he only has Super Saiyan and Super Saiyan Two.
