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 Tanjiro and Nezuko have both passed the final Selection. And both Doctors have knocked half of year off getting the Tardis fully functional. Goku has to now attend pillar meetings. But Goku somehow has forgotten about Tamayo and Yushiro for like two years.
Chapter 4: the argument between Doctors. Goku is half caught.
Goku is a the pillar meeting and spying on Muzan at the same time by using the multi form technique. Kibutsuji noticed Goku spying on him. All of a sudden this half of Goku finds himself in the infinity fortress and is teleported my a demon blood art at the sound of a instrument. Muzan confronts Goku and says don't bother trying to escape since no one can escape the infinity fortress alive. Goku says really now well I be the first them. Has he puts two fingers on his head and disappears and reappears at his other half at the pillar meeting. Everyone is wondering why they see two Goku's until both Goku's join back into one. Goku says what I can spilt into four but the more I split my power is halved between each copy.
Shinobu asks so where has your other half been? Goku says spying on Muzan Kibutsuji. Everyone one is shocked hearing this. The wind pillar Sanemi Shinazugawa says how did you escape him? Because no one escapes his infinity fortress alive ever. Goku says I easliy escaped by using instant transmission. I have already explained everything about me like two years ago.
Meanwhile with the Doctors, Tanjiro and Nezuko.
Tanjiro says I can smell a lot of sadness from the female Doctor. The 10th Doctor goes anything you want to tell me? 13th Doctor says spoils. 10th Doctor says spoils? Well I can't believe I am going to do this but I want to know what happened in my future to make you/me like this? 13th Doctor says you have to find out the long way round! 10th says come on it's not like I am going to remember after the timelines are fixed. 13th Doctor says I just can't tell you anything. 10th Doctor says let me guess it's probably something to do with Gallifrey. Since I know it was saved your living proof since you are on a new life cycle! So what is it? Has Gallifrey fallen again? That look on you tells me it has. Tanjiro says I smell that she is really upset and angry at the same time! 13th Doctor says right you got me other me! 10th says what happened to it? 13th Doctor replies by saying the Master. 10th says the Master?! Why? Oh forget it I just have to wait the long way around which is like over two thousand years.
Nezuko says well so Doctors your both older than the demon we are meant to be fighting against. Both Doctors says well yes I guess I am! Goku appears. Goku says how has it been going? I do feel like I kind of forgot something. 10th Doctor says well I wonder what damage has been done to the space time continuum since two of me have been together for over two years. Goku goes doctor hmm. Oh now I remember. Hey Tanjiro, Nezuko and Doctors do you both want to come with me? Tanjiro and Nezuko both say sure. 10th Doctor says alright them. Okay them said 13th Doctor.
Goku uses instant transmission and they appear outside of a house. Nezuko says wait I remember this place from my dreams. 13th Doctor says those aren't dreams those are pass memories I guess that you have been reincarnated has yourself with pass memories from at world. Yushiro appears and says oh you finally came back just after two weeks and who are these other people? Goku says sorry about! Tanjiro says my name is Tanjiro Kamado. Nezuko says my name is Nezuko Kamado. Both Doctors says I am the Doctor. Yushiro goes wait are you the Doctors that turned a demon back into a human? Both Doctors say yes. Tamayo says Yushiro who's that? Yushiro says it's Son Goku and he's brought other people with him. Tamayo says let them in! Tamayo says so Doctors I heard that you both have successfully turned a demon back into a human and I have been trying to do that for years with no success at all. 13th Doctor pulls out a blood vile and says well it was his blood here that helped made the cure success but it's like four years old now. Tamayo asks where is blood come from. Goku says I got it from an alternative version of my self two years ago through a time tear.
Goku says see this girl Nezuko? Tamayo says yes I do see her. Why? Goku says because that blood is a demon version of her blood from a other timeline. Nezuko says I have dreams that I was a demon! Tamayo dreams that you were a demon that's strange. Let's see do you want to help Doctors? Both say sure! Okay lie down and try to dream Nezuko. Nezuko goes to sleep and starts dreaming. Tamayo uses a spell to check her dreams has the Doctors place their hands on Nezuko's head and look telepathically. Tamayo and the Doctors are shocked too see that she was a demon in her pass life along with finding out what happened to everyone in that timeline.
10th Doctor says that confirms my other self is right she in reborn and reincarnated into herself with pass memories. Goku also telepathically looks at Nezuko's dream. Goku goes dam well at least that won't happen in this timeline. Tamayo says I am surprised that Nezuko in her pass life was actually a demon and her blood was also involved making a cure to turn demons back into a human sadly that isn't possible here.
10th Doctor says hey myself are you hiding more info from me. 13th Doctor says yes but your not allowed to know about it just in case you try and investigate yourself. 10th Doctor says well just say it. 13th Doctor says alright I tell you but you better not investigate yourself. 10th Doctor says okay I promise that I won't investigate. 13th Doctor says well I came across a pass version of us that I don't remember another female doctor! The 10th Doctor says what I don't ever remember being a woman I just know that I will become a woman once I become you. After all I know my pass selves. Both go wait I remember something really bad. 13th Doctor says it must be really bad if we both remember it.
In another part of space:
Well other me we have to stop the Daleks. I can't agree more. The Daleks go the Doctors have destroyed our army. We are the last group of Daleks left. 4th Doctor says well do you give up? 11th Doctor says well Daleks never surrender. A Dalek goes the portal to another dimension is ready. Another Dalek goes we will invade this dimension and make more Daleks low intelligence will be converted into this human looking Dalek units that we can use to infiltrate places. High intelligence will be fully converted into full Daleks! 11th Doctor says well that doesn't sound good at all. Wait why do I remember encountering the Daleks in that dimension? 4th Doctor says I don't know anyway would you like a jelly baby? 11th Doctor says thanks I do think it's time for you to depart. 4th Doctor says well I better be going it's good to know that my future is in safe hands. 11th Doctor goes well I might has well try and beat the Daleks to where there going.
Back in the Kimetsu No Yaiba universe with Goku, 10th Doctor, 13th Doctor, Tamayo, Yushiro, Tanjiro and Nezuko.
Tamayo goes what's wrong Doctors? 13th Doctor says something really bad. Tamayo says is it demons that Kibutsuji sent after Goku. Goku says no it's something different. Tanjiro and Nezuko ask what's going on? Has everyone hears a Tardis appear with the 11th Doctor stepping out. The 11th Doctor says oh no not you with your sandshoes. 10th Doctor says their not sandshoes! 13th Doctor sorry but they are! Not you too! Said the 10th Doctor. 13th Doctor goes so what brings you here? 11th Doctor says wait I become a woman in the future? 13th Doctor says yes! 11th Doctor says I am here because the Daleks are going to invade. Both 10th and 13th Doctors says the Daleks! That's really bad!
Tanjiro, Nezuko, Tamayo and Yushiro all ask who's this other man? 13th Doctor says it's just another version of me. Well them lets get to work on stopping the Daleks. Goku comes in and goes oh another Doctor. 11th Doctor says Son Goku your here too! Goku says yes I am and since there is now a third Doctor here must mean that things are getting really bad. And did I hear Daleks? Tanjiro, Nezuko, Tamayo, Yushiro and Goku all ask what a Dalek is. The 13th Doctor says that the Daleks are evil beings with no emotions expected hate and fear. 10th Doctor says I am their most hated enemy. 11th Doctor says because I have always stopped them. Tanjiro ask why did he finish what was being said! 13th Doctor says well sometimes my other self's like to finish each others sentences.
11th Doctor goes so who is this Muzan Kibutsuji? Tamayo says he is the first ever demon and he's over thousand years old. 11th Doctor says so younger than me I can't even remember my own age so I feel like I lie about my age. A crow arrives and says Tanjiro, Nezuko and Goku all three of you have to come to an emergency meeting which involves every demon slayer since a village has been massively destroyed. Goku goes come on Tanjiro and Nezuko we have to go. All three Doctors say we are coming with you. Everyone puts a hand on Goku and Goku uses instant transmission to the Demon Slayer Corps HQ.
The pillars are glad to see Goku arrive with the two new rookies. But they ask who are these three? The 13th Doctor says all three of us are the Doctor. The master of the Corps appears and says in a kind way and voice you three shouldn't be here. The 11th Doctor says I might know what happened to that Village and I don't want anyone here going there except for all three of me and Goku! The pillars ask why? 13th Doctor says because you could all die! The master of the Demon Slayer Corps says but slayers do die in battle against demons Doctors. The 10th Doctor says but there not demons that attacked the Village. What attacked the Village are called Daleks! Everyone asks what's a Dalek? The 13th Doctor says that the Daleks are evil beings with no emotions expected hate and fear and they kill anything none Dalek! 11th Doctor says the Daleks plans are to convert people into Daleks. Low intelligence will be turned into units that look human to infiltrate places. And people with high intelligence will be fully converted!
They asks what do they look like? 10th Doctor says they look like bins with orbs on them and they have an eye stalk, a plunger and a gun. They are armed direct energy weapons that can kill anyone with one shot unless you have strong shielding. But I am afraid that you can't engage them with a sword since the sword would break hitting their armour and you will be killed before even getting into striking distance.
Goku says well I can possibly shield myself from their attacks and destroy them with ki blasts. 11th Doctor says we don't know how many Daleks there are. Goku says I only sense like twenty Daleks shouldn't be a problem. 11th Doctor says but those Daleks escaped me and my 4th self. 10th Doctor asks 4th self where is he? 11th Doctor says he's gone back to his own timeline. Tanjiro and Nezuko both say that they haven't got their swords hey.
At the Infinity fortress:
All six upper demon moons and the three remaining lower demon moons are all called to a meeting. Upper moon Demon three goes why are we all here? All six upper demon moons haven't been called here all at once in over hundred years! And why are these three lower demon losers here? Muzan goes enough now let's start this meeting. Muzan says right this Demon Slayer called Son Goku is a really problem and he needs to be taken out. Is that it said upper moon demon one. Muzan says I also got reports from another demon that these weird things have came out of nowhere and destroyed a village. What said the demon moons. Muzan says I want upper moon one to investigate the village and kill any demon hunters you come across and you other eight too continue looking for the Blue Spider Lily flower. Understood!? Yes sir!
Goku arrives at the village. A Dalek goes life form detected. The Dalek finds Goku and goes bio scanning! Life form Saiyan? Threat level high. Exterminate, exterminate, exterminate! The Dalek shots Goku but Goku takes notice and blocks the blast with an energy barrier. Goku then shots a ki blast at the Dalek. The Dalek instantly dies. All of the other Daleks are alerted. But the sun has just set and upper moon demon one appears. A Dalek managed to go bio scanning. Demon! High threat level, exterminate, exterminate, exterminate. The Dalek shoots upper moon demon one and goes fire power non-affective. Before the Dalek could scan for a weakness. The Dalek got cut in half. Some Daleks have surrounded Goku and Goku goes dammit they have be surrounded and that is a weird looking Dalek? A Dalek goes special weapons Dalek is in position! Exterminate! Exterminate! Exterminate!
TBC
