I don't own Dragon Ball and Kimetsu No Yaiba.

Last time: Pillar Training began. Goku, Emily and Future Nezuko all undergo training with Bardock. Goku tries a little bit of the Pillar Training. Kagaya Ubuyashiki's health has gotten way worst that he's coughing up blood and can't move. Tamayo has been called in to help against Muzan.

Chapter 23: The start of battles:

Gyomei goes the most important thing is the body's core... the limbs. Stabilising your body with strong limbs will lead to accurate attacks and indefatigable defence. First, train by having the waterfall beat you... Then carry three logs on your shoulders... The logs are huge. Gyomei still going. Finally push this rock through a town...

Tanjiro is staring at the logs. Zenitsu is staring at the rock. Gyomei goes my training is simple. It's just these three things. The training involving flames coming from below you was too dangerous. So I removed them. Goku thinks (I need way more than three logs.). Tanjiro goes I'm sorry. Zenitsu has passed out. Gyomei goes dump him in the river.

Tanjiro puts Zenitsu into the river. Zenitsu ends up going gyaaaaaaaaaaah! Shoooooocowwwlld! The river is even worse in mid-winter, but I'm dyiiiiing! Oh my god, what's wrong with the water in this mountain river! I'm dying! Gonna hurl. Tanjiro goes Zenitsu! Zenitsu goes land... L-Land... Waaahhh I feel like my innards are rotting! They're screaming! Hya... Hyaaaaaaaahh! Oh, oh shit, even when I'm out... it's to late! I'm freezing! Murata gives Zenitsu a certain look. And goes hug... The rock... It's warm...

Goku goes I better go to the special training future Nezuko want to do with me. I see you all later. Oh, and I'm going to check on Ubuyashiki just to see how he's doing. Goku disappears. Zenitsu goes straight onto the rock. He goes s... so warm! Rocks are so warm! It's like I'm inside my mommy's arms. Waaaaaaaaaaw Mommmmyy. While on the rock.

With Goku:

Goku goes hey! Ubuyashiki! Amane! Kiriya! Hinaki! It's me Goku! I'm just checking up on you lot! Amane comes out and goes Goku! Goku goes I sadly sense Ubuyashiki slowly getting closer and closer to death. Also, what are you planning to do against Muzan? Amane goes Kagaya! It's Goku! Kagaya goes come in! Goku goes oh man! Too bad I can't do anything to help save you, Kagaya. What's your plan? Kagaya goes to blow myself up. But Amane is going to do it. Goku goes buts that's going to kill her along with Kiriya and Hinaki! I'm not going to allow it! Let me set off the explosives! Since I can easily survive without a scratch. But I'll then have to fight Turles and possibly Cell! I don't see the point of your wife and two of your kids losing their life's! Ubuyashiki's goes alright, Goku. You can set off the explosives. Goku goes right I got to get going for my special training. See you lot later! Amane goes alright! See you later!

Back with the others:

Tanjiro in the water thinks (ghhh, it's cold. This is hard. Waterfall training is hard. I wonder how hard Goku's is? Inosuke is working hard though... I should too. Hm? I can't hear his chants.). Tanjiro goes uh, Inosuke!? Ino... Ahg, oh God! Oh God!

Tanjiro "After I revived Inosuke, I trained under the falls too. The chants were for focusing. They also helped me let everyone know I was conscious." He currently goes man, the waterfall training alone was really hard. Water falling from high places is really heavy. If I let my body my neck might snap. I wonder how Goku is getting on?

Goku and Future Nezuko:

Future Nezuko goes you were ready meant to go Ultra Instinct. In the Tournament Of Power so I'm go on the train you. How to access it and maintain it for a while in your current body. Goku goes okay then. Also so you can use it against Cell! Goku goes okay let's get on with it. Nezuko goes clear you're mind and control your emotions. Even though it's kind of the same way with the see through world. Nezuko closes her eyes and opens then with her pink eyes now sliver with heat coming off her body. Goku goes okay, so I have to try and do that?

Not knowing that current time Nezuko is secret watching while suppressed. She thinks (I already knew about you future me from when Rengoku died. I can't believe that future me forgot that I can sense Ki).

Goku closes his eyes and opens then with sliver eyes along with heat coming off his body like Future Nezuko. Past Nezuko thinks (wow! The amount or pressure coming from them.). Goku and Nezuko can't touch each other. They stop and go out of the technique. They both hear someone go well done you two. Can I join in. Nezuko goes Gohan Black! How did you break free? And why do you want to help us? He goes the other Nezuko you sensed earlier was the you from the time I came from. It's just that the time I came from is in danger with other dimensions. I came here. Because I knew that you would come after me. I faked being evil. I just wanted you stronger for those events. But the main issue is that I took Gohan's body after his death.

Goku goes what!? Black goes spoils. Anyway did you sense something off, when you left Sonic's dimension? Goku goes now that I think of it I did... No! That bastard demon didn't!? Black goes sadly he did. Goku goes I must stop Cell here. I do fear that he might have Frieza's golden form with the Kaio-ken. I think he's waiting to attack when the battle against Muzan starts. I wonder how Tanjiro and the others are getting on.

With Tanjiro and crew:

Tanjiro is on the rock. Murata goes m-man... You and that boar are amazing. It took me until evening to finish the waterfall on the first day. I just couldn't get used to the water. Anyway, ever since I started getting used to the waterfall, I've been stuck on the log training... Tanjiro goes a-awesome Murata-San... Murata goes t-ten days of this...

'Goku, Future Nezuko and Gohan Black have been training ten days straight.'

Goku goes man I'm going to check on Tanjiro and the others. Goku Instant Transmissions to Gyomei. Goku goes right I'm back after having my special training. Now I'm ready to see how this one goes. Even though I need more than three logs for each shoulder. Gyomei goes take off your top and get into the river at the Waterfall. Goku goes okay?

Goku goes into the water and goes wow this is so cold. Not as cold as the Earth's second to last Ozone Layer when I thought Beerus as a Super Saiyan God. So, I'm kind of use to this, usually. He heads to the Waterfall. Goku goes man! This aren't doing me that good. The force of the Waterfall isn't enough.

The others are eating. Inosuke goes he's awesome. The ball ball old guy. Tanjiro goes you mean Rock Pillar Himejima-San. Don't give him weird nicknames. Inosuke goes he gave me the chills ever since I first met him. No doubt about it. Tanjiro goes you eat bones, Inosuke? Inosuke goes this guy is the strongest human demon hunter. Since Goku and Goku Black are aliens and Nezuko's a demon.

One of the boys thinks (really?). Tanjiro goes ahhh. Yeah, I figured. Himejima-San's the only one with a different smell. Did his mark show up already? Inosuke eating his 10th fish. Tanjiro goes wouldn't be surprised if it did. Murata thinks (yeah, uhh... We're normal people who didn't rise through the ranks like monsters, so we have no idea what you're talking about. Also the fish Tanjiro cooked is good.).

Zenitsu goes I don't believe it. I'm sure that old man can't move that rock across town. He's just having fun picking on younger people.

Goku thinks (man! This logs are so heavy! Especially with 50 on each shoulder. Which makes 100. With 25 rocks tied up on both sides. Also, the part I'm wearing my weighted clothing too. Along with the demon slayer uniform. And I'm not using Ki. But where is a little bit extra weight coming from?). Nezuko shouts how are you getting on down there? Goku goes Nezuko? So you're the little bit of extra weight. Why are you sat on top of the stuff I'm training with? Nezuko goes to make it a little harder for you! Goku goes I know you can regenerate! But what you're doing is dangerous especially if you fall off. Also the cure to turn you back into a human might be done in a few days. But I don't know how many! Nezuko goes okay I'll get down. Can you get me a little bit closer to the tree. Thanks. As she jumps down the tree branches.

'Goku's weighted clothing in total is 1.2 tons.'

Back with Tanjiro, Zenitsu and Inosuke:

Tanjiro goes no, no. Himejima-San can push, bigger rocks than that. Zenitsu goes you think I'll believe what you say right away? You're trying to trick me. Tanjiro goes no, no... You have good ears, Zenitsu. You can tell whether I'm lying or not, right?

Himejima is going Namuamidabutsu. Namuamidabutsu. While slowly pushing a huge rock. Tanjiro goes ah, there he goes. Himejima-San's amazing. Maybe I can be like that!? Zenitsu ends up going the hell you can! You moron! What's with the happy-happy face! While heavily poking Tanjiro who going ow ow ow!

Zenitsu goes that man is insane! And he's as big as a bear! Tanjiro goes but... Zenitsu goes shut it! People are born giant and little! You know that! Inosuke goes I'm full so I'm gonna push rocks and carry logs. Zenitsu goes waahhh you dumb positive guy! I have no place here! Tanjiro goes oh dear.

Goku shows up and goes Zenitsu they both at least want to get stronger through the easier training methods. Zenitsu goes that's easy for you to say! Oh my god! Tanjiro goes wow! How many logs are you doing there, Goku? Goku goes 100 logs and 50 huge rocks. Also my weighted clothing in total weights 1.2 tons. Zenitsu goes and I thought Himejima-San's insane! Goku goes I'm using my normal strength without Ki. Also Nezuko was on top of it earlier. Zenitsu passes out. Tanjiro goes Nezuko was on top of that!? Goku goes yes. The one waiting for the cure. As he puts the logs and rocks down and picks up on huge rock and spins it on his finger like a spinning top. She's gone straight back to hiding.

In a few days Tanjiro finishes the waterfall training. And the log carrying training also in a few days. And ends up stuck on the boulder. Tanjiro thinks (my legs are going backward! Guaahh I can't push it away! Goku also said "Train without using the Kiao-Ken. So you don't break you're body."). (Himejima-San's training was hard. But is wasn't compulsory. If you wanted to quit, you could always go down the mountain and give up.). As some people have given up and are leaving.

A bit later on:

Murata goes I kinda realised from the training why there are so few pillars now. Tanjiro goes why is that? Another slayer there called Yoshioka goes I kinda know why too. Another one called Nagakuira goes it's so hard that everyone runs away. Another one called Shimamoto goes yeah... Another one called Noguchi goes yeah, and just like the blond dude, getting beaten down by the difference between us and Pillars breaks our hearts. Murata goes and they just keep doing it as if it's natural. Pillars are amazing.

Tanjiro goes yeah... Murata goes actually, you're really good at cooking rice, huh? And you're good at cooking fish. Nagakuira goes yeah. Tanjiro goes I'm the son of a coal burner. Cooking is like heat checking! Murata goes oh, I see! Tanjiro goes you're all luckily that Goku aren't here. Because we will not be able to eat anything.

Goku and Future Nezuko are training.

Goku goes Nezuko shouldn't you hiding too? Nezuko goes you're kidding me right? I can easily wipe out Muzan in a blink of an eye. Goku goes I can also do that. But our main focus is Cell! And keeping our base power even. Nezuko goes we're doing a really great job at that. Actually where is Goku Black and Bardock? Goku goes I don't know.

Bardock goes come on keep up! Black goes but I'm not sure how long it's going to be for my cure. Bardock goes I know that's going to weaken you. But your needed against Cell! The most frustrating part is that he could have Frieza's and Cooler's golden forms! Black goes but I don't have Mystic like Goku! Bardock goes true! But I'm the best chance against Cell and Evil Karakot! Especially with Super Saiyan Blue Evolution and Kiao-Ken times ten. Black goes would it be better for me to train with Goku and Future Nezuko. I might be able to tap into what they call Ultra Instinct.

Bardock goes I wonder if I can merge Super Saiyan God and Super Saiyan Four? Along with the Kiao-Ken? Black goes how broken in power do you want to be? Bardock goes even better! Super Saiyan God Super Saiyan Four Evolution with Kiao-Ken? Oh, yes! That's very power broken! No even better! Super Saiyan God Super Saiyan Five Evolution with Kiao-Ken times hundred? Black goes are you insane!? He thinks (I hope that there's no Super Saiyan Six!). Bardock goes it will allow me to get missions done easier. Without having to worry about opponents over powering me. Black goes but aren't you above Beerus, just in Blue? Bardock goes I'm not sure. Probably in Blue Evolution? Anyway let's get back to training.

Back with Tanjiro:

Tanjiro tries pushing the rock six days straight and it still won't move. Tanjiro now on the ground thinks (nothing happened today... What now? We don't know how long the demons will stay quiet. I gotta hurry... Maybe I just lack simple muscle strength. Or maybe there's a way with my breaths? I think I can do it with the Kiao-Ken. But despite all my training, the mark just doesn't show up...). Genya appears and goes hey, did the mark on your forehead get bigger? Tanjiro in shock goes ah, Genya!

Genya goes you okay there? I was worried since you stopped contacting me after that. I held myself back and got scolded by Himejima-San. And that was all after I was told never to get near my brother again. Sorry for getting you involved. Thanks for protecting me. Tanjiro goes oh no, it was nothing... But more importantly, your mark. Oh, the birth-mark got thicker? Genya goes yeah. Tanjiro goes nobody told me about that. Genya goes well, they see your face everyday, so nobody could tell. Don't you have a mirror? Tanjiro goes nope. Genya goes I'll lend you mine. In the background both crows are telling each other to die.

Tanjiro thinks (did it really get darker? Yay, I'm happy.). Genya goes so you're on the rock training. Me too. Tanjiro goes well it's not budging at all. Can you move it, Genya? Genya goes I can. Tanjiro goes ehh? Genya goes don't guys know about 'repeating actions'? Tanjiro ends up with a smile. Genya goes so you don't... Himejima-San sucks at teaching. So you gotta watch closely or you'll fail. He's actually doing a set of pre-determined movements in order to maximise concentration. In my case, I chant prayers. Tanjiro goes so Himejima-San does it too! Genya goes yep. That Namu-Numa thing he says. Not knowing that Himejima is listening behind a bunch of trees. And thinks (Namu.)

At night time. Some mobile demon eye balls with the number four in the eyes are looking around.

At the Dimensional Infinity Fortress:

A demon with a Biwa goes I have found one more person. Now I know sixty percent of the Demon Hunters' Whereabouts. We know where one version of the Sun-conquering girl is. But that one's to powerful. But I can't find the weak, one. Muzan goes Nakime, you've grown a lot more than I expected. It's wonderful. I am very honoured. And now I suppose... Try here. Pointing at a map. Nakime goes understood. If the eyes don't get destroyed. Muzan goes weak current goes Nezuko I'll find you very soon. Same with Ubuyashiki. Wait eyes getting destroyed? Nakime goes by that Goku. Turles goes Nezuko's really good at hiding her energy. That I can only sense the future version.

With Goku:

He goes ewe, these eyes are so gross. I must keep on destroying them. I can't sense them but I can see their aura.

Gohan Black goes I should try and get use to Super Saiyan Rose and Mystic combined. Especially since I'm going to help against Cell! I also need to help Goku try to get use to Super Saiyan Three Mystic.

Back with Genya and Tanjiro:

Tanjiro goes "According to what Genya taught me, 'Repetitive actions' is a technique that opens all five senses. Genya may not be able to use breaths, but he can achieve full focus another way-repetitive actions. When Himejima-San and Genya use it, they remember their anger and painful memories. That makes their heart rate and temperature go up. As we talked about various things, the signs were pointing to the possibility that this might be the same thing as my mark coming out. But Himejima-San and Genya had no marks, so we cocked our heads in confusion. By doing these 'Repetitive Actions', you can raise your focus at any given moment. It would be nice if I could learn to maintain my darkened mark forever. My repetitive actions were remembering the faces of all my loved ones. Then recalling Rengoku-San's words. "Set your heart ablaze!" And with that, I raised my focus to its maximum limit."

Tanjiro is going guaaaaaaaaaaaaaaaaahh! "I couldn't do it the beginning. But I was able to use all of my strength I had doing these repetitive actions. And after a number of times, as I did them again and again, my body began to remember the way to bring out that power through these actions."

Tanjiro is sweating like crazy. Goku is watching from above. Tanjiro finally starts to slow push the boulder. Zenitsu goes he did iiiiiiiiiiiiit! Tanjiro blucking did iiiiiiiit! That monsteeeerrrr! Inosuke goes shit, I lost! Goku shakes his head at Zenitsu's and Inosuke's reactions.

Tanjiro thinks (n...not enough! If I ease up for a moment, I'll lose strength and stop pushing it. Don't just use the arms! Legs! Use your legs! The lower body has more muscles than the upper body.). Inosuke goes Tempura! Tempura! Pig assault! And starts pushing his own boulder. Goku thinks (I remember trying to push a way bigger boulder than back when I was a little kid. Training under Grandpa Roshi.).

Zenitsu thinks (Inosuke moved the boulder too! This sucks! I'm gonna be the only one left now! This sucks!). Chuntaro arrives carrying some paper. And chirps. Zenitsu goes huh? A letter?

Tanjiro goes haaaaaaah. Haaaaaaaaaah. He thinks (I moved it across a town! Now Himejima-San's training is over. Huh? What... Oh... I... I'm dehydrated! Because of I sweated out an entire waterfall without drinking anything... Z... Zenitsu, Inosuke! Murat a-San! Goku! I might die here! S... Some one!). Goku thinks (oh man, Tanjiro pushed himself to hard without having a drink. Hmm?).

Himejima ends up pouring water out of a bottle at Tanjiro. Tanjiro ends up thinking (ah... Himejima-San... Saved me...). Himejima is going Namu-Amidabutsu, Namu-Amidabutsu. Goku thinks (I'm now wondering what Namu-Amidabutsu means. Oh wait my phone. Now let's see here? So it means he reads to himself. "Namu" means "I take refuge", and "Amida Butsu" means "in Amida Buddha." That is one great meaning of the Nembutsu. Hmm. Well Gods do exist. I'm still wondering when I will have my rematch against Beerus. I wonder how their doing?).

Dragon Ball Universe on the Room of Spirit and time:

Vegeta thinks (to 2,500 times Earth's gravity in a few years. But days out there. I'm not going to let that clown Kakarot surpass me again. Also, I got a new form. And that Kakarot's an idiot! I know he had this potential by the Old Kai. Also he might have gotten a lot of training in with some Zenkai boosts! When he's turned back into his proper body age. All of his boosts while massively increase! I might as well take a break. Especially since I trained up to 2,500 times Earth's gravity in Three Years. I could do with a huge amount of food!).

Out of the time chamber:

Bulma goes man! I can't believe that I found so many faults with the machine that needed fixing. And the part that the fuel is taking longer than I thought. Also, when is Vegeta coming back? Vegeta goes Bulma? Are you almost finished with the Machine!? Bulma goes I might need an extra day or two. Vegeta goes shouldn't you take a break? After all you're pregnant remember? Bulma goes I guess you're right. I should have my father try and finish it. Bulma goes father!? Can you please finish this machine please? I have the instructions and blueprints on the table! Her father goes sure thing dear! Bulma goes thanks! Also, Vegeta get a bath or shower, since you stink. Vegeta goes alright, alright! Wait can't you try and get, Gohan to help your Father? Bulma goes let me call him.

Ring, ring. Gohan goes hey Bulma? What's up? Bulma goes can you help my father finish the machine to get Goku back? Gohan goes I'll try? They hang up. Videl goes was that Bulma? Gohan goes yeah. She wants me to help her father on the machine to get dad back. Videl goes well I'm not going to stop. You since we really need him back. Gohan goes yeah. Well I better get going.

Later Gohan arrives at Bulma's:

Gohan goes hey, Mr Briefs, I'm here to help you with the Machine to get dad back. Mr Briefs and thanks. I can't do it all by myself. Especially with my daughter pregnant. Gohan goes thanks for reminding me of that. Now let's get started.

Back at the Kimetsu No Yaiba Universe:

Tanjiro thinks (uh, did I die? Oh, I'm alive.). Tanjiro goes th... Thank you very much. Abababa. (He's still giving me water.). Himejima goes the Rock Pillar Training is complete. On top of that, you did the right thing in the village. I accept you... Goku lands. Himejima goes I also accept you, Goku. Tanjiro goes village? Gaph... Gagh... Water-water okay now. Goku goes oh yeah, the Sword Village. Himejima goes you prioritised the humans in the Swordsmith Village over your sister when crisis struck... Tanjiro goes oh... Look... Himejima goes there's no shame in that. You truly are a swordsman. You acted the right way. You should be proud... Goku... Your also truly a swordsman. Goku goes thanks.

Tanjiro goes no, you're wrong. Nezuko made that choice, not me. I couldn't come to a decision and left the villagers in danger. Goku goes I better say this now. Future Nezuko told me that she conquered the sun there. I could have used Instant Transmission to take Nezuko to safety and kill the demon. But I was to business fighting the most powerful part of the demon with Mitsuri. Tanjiro goes you known the whole time? Goku goes yes. If I didn't Future Nezuko said that a lot more life's would have been lost.

Himejima goes since that saved life's that means you did the right thing. Also, Tanjiro I cannot accept your acceptance. Has he thinks (children are pure and naive. Weak. Quick to lie. Completely fine with cruelty. Selfish things. But this boy is truly different.). Tanjiro goes I really want to go down the right path all the time. But I don't know what will happen next. Someone always comes to help me so I end up making the right choice and everyone comes out okay. But that time in particular was an extremely close to call. So please don't accept as simply as that. Thank you for the water. And thank you for the training today. I learned a lot. Himejima goes my doubts are gone. No matter what the others say I will accept you Tanjiro Kamado. Goku I accept you to no matter what the others say too.

Goku goes the thing is that I'm not far from turning fifty years old. Even though I was only in Sonic's Universe for 1.5 months. I got back home and I aged 1.5 years older. All of the others including here in total is damn six years. Which means I am over fifty years old. Man I'm only meant to be forty-four years old. And yet here I am in a eighteen year old body. Himejima goes hmm. That doesn't matter. I still accept you Goku. Tanjiro ends up going uhh... Why? I... I don't get it...

Himejima goes long ago, I raised some kids who had no family in a temple. Our affinity in having no blood connection helped us bond together very well. I raised them like my family. And I wanted to keep life that way forever. But then one night, a kid disobeyed the temple rules and didn't come back after the sun set ran into a demon. In order to save himself, he told the demon to eat me and the eight kids at the temple. Tanjiro and Goku look on. Himejima goes in the area I lived in the threat of demons was very well-known. And I always burned Wisteria incense at night. That kid put out all of the incense and invited the demon into the temple. Four kids were killed immediately. I tried my best to protect the other four but three of them didn't listen to my words. Back then, I didn't eat lot, so I was skinny and weak. And my voice was soft so I couldn't shout loudly. On top of that, a blind person like myself wouldn't be of use to anyone. That was what those kids were probably thinking. Tanjiro thinks (so Himejima-San can't see!?).

Himejima continues the only one who listened to me was the youngest child, Sayo. She was the only one who hid behind me. The other three kids didn't stay by my side and ran... They all had their throats ripped out in the darkness and they died. I fought because I thought I had to protect Sayo at all costs. Punching a living being felt like hell to me. It felt so disgusting that I will never forget it for the rest of my life. For the first time in my life, I used my fists with full force, and I had a frightening amount of power. If I never got attacked by that demon, I would have lived my entire life not knowing I was strong. I punched the demon's head in again and again until the sun came up. I lost a mountain of things that night. I was wounded, but I managed to protect Sayo. Then when people came to help, Sayo told them "that man's a monster. He killed them. He killed everyone.

Tanjiro goes no way... Goku starts thinking. Himejima goes it was terrifying situation, so she was probably confused. She was only four after all. Nothing to be done... That's how kids are. But in my case. I at least wanted to Sayo to be thankful because I protected her. I wanted her to say thank you for fighting on her behalf. If she had said that one thing, I would have been saved. But kids have their hands full of thinking of themselves. The demon's corpse turned into dust and vanished, so only the children's bodies remained. I was imprisoned and charged with murder. If Oyakata-Sama had not intervened, I would have been executed. But ever since then, I have to harbour deep doubts and suspicions. And of course, I doubted you both. No matter how virtuous a person you both are, once you both get pushed into a corner, your true nature will come out.

But Tanjiro you never ran. You never turned away. You stayed honest and never lied. It's something so simple, but only a few people are able to do that in every situation they face. You are a special child. I say this after having seen many humans with my heart's eye. So this is absolute. Every person has an uncertain future. But I will help you from now on so you won't take a wrong turn in life... Tanjiro goes I will do my best... Thank you so much... Himejima pats Tanjiro's head and goes my training is complete... You have done very well...

Goku goes Tanjiro your physically like a human version of me. And I'm being fully honest here. Also, Himejima-San. I believe that the kids might have been trying to get stuff to fight the demon to protect you since you're blind. Also that Sayo might have been talking about the demon. But it disappeared. Which is why you got into trouble. But we will sadly never know. Well we'll see you later. Himejima goes okay.

Later on: Goku, Tanjiro, Genya and Inosuke are all sat down eating:

Genya goes Himejima-San is a pretty good person in his own right. Despite the fact that he said he won't make his successor because of having no talents, he figured out that I was eating demons, so he made me his disciple. He introduced me to Kocho-San and had her check on my condition. Tanjiro goes oh, really now! Inosuke continues eating and Goku doesn't say anything. Genya goes but every time I see her, she puts on this disgusted face and scolds me. You and Goku seem relatively stubborn too, so she must have also told you both off, I think. But you both never grumbled about it.

Tanjiro goes well, if I wasn't able to use breaths, she might've treated me the same way. Are you okay though? Goku goes with me it doesn't matter if I could do breaths or not. Since I'm already multi-talented. With my martial arts and some of my other fighting techniques without the use of Ki. And possibly the part I'm a very quick learner. Tanjiro goes your not properly wrong there. And Genya I'm sure Shinobu-San is worried about your body too, Genya.

Genya goes maybe? Tanjiro goes of course! I'm gonna go see Giyu-San once I'm done eating this. Wanna come too, Genya? Genya goes no, no. I haven't moved the boulder across town yet. I'm really close to it! Well, I can't use breaths. Inosuke goes hahaha, you can't use breaths!? Shrimp!

Inosuke and Genya start going after each other. Tanjiro goes hey, hey, hey! Goku just shakes his head. Tanjiro goes I just wanted to have a chat about something if we went together. While keeping Inosuke pinned by sitting on him. Genya goes about what? Inosuke goes move it! Tanjiro goes about the Wind Pillar... Your brother. About him. Genya has gone silent.

Tanjiro goes outside. Goku teleports to Bardock. Goku goes hey, father. I'm here for a bit of training. Bardock goes only for a few minutes, Kakarot. Since I really need to get some food. Goku goes a few minutes is better than nothing. Even though I do need a small break. Well I think I better rest instead. Bardock goes okay son. Goku teleports to Future Nezuko. She goes oh, Goku? Goku goes you're the closest one to the room to rest in. Nezuko goes well I did have a small nap and just got up. Goku goes into the room and goes I see you in a bit.

Tanjiro goes oh, Zenitsu! You're here! Did you move the boulder? Zenitsu goes no. Not yet. Tanjiro goes oh, okay... I'm going to the next training... You gonna be okay? You haven't talked for, a while, Zenitsu... And I'm worried... Zenitsu goes oh. Okay. Good luck. I... Have to just come to terms with what I should do. No, what I have to do. Tanjiro goes but... but... I'm worried. Zenitsu goes you're a really nice guy. Thanks but... This is something I really have to do.

A little later with Tanjiro walking to Giyu's place:

He thinks (is Zenitsu okay? And Nezuko. She been under someone else's care this whole time. Maybe she's lonely. But since she has all of her humanity besides being a demon I think she's possibly fine. Huh? Uhhh, this is it. Giyu-San should be around here, right? Ah! There's a building. Wait why didn't Goku teleport me here?).

Sanemi and Giyu are both training with each other:

Sanemi goes Breath of Wind First Form Deer Skinning Cyclone. Which is a huge tornado charging at the target. When Sanemi charged in. Their both using wooden swords. But Giyu's gets a bit damaged. Tanjiro thinks (s... So fast! But I can see them! I can follow their movements!).

Sanemi goes Oraoraa! What's wrong!? You're no different from the rest of us! Tanjiro thinks (oh... well, that's not what he...). Giyu goes Breath of Water Fourth Form Striking Tide! Sanemi dodges and goes too sloooooow! Breath of Wind Fifth Form! Giyu goes Breath of Water Seventh Form Piercing Rain Drop! Sanemi Winter Gale! Both their wooden swords break. Sanemi goes okay, time to pummel each other to death with fists.

Tanjiro goes wait, wait, wait! Please wait a minute! You can't go killing each other! Has he got in front of Giyu. Sanemi goes shut up, dammit. You ain't even supposed to get near me. And you dared to peek in on us, you little twerp.

Tanjiro goes can't we all just share some Ohagi or something? I'll make enough of them to fill your tummies, so... Sanemi goes making fun of me now, huh... Tanjiro goes wha? No, no, I'm serious! You like Ohagi, don't you, Shinazugawa-San? When I was training at your place, I smelled the slight fragrance of Mochi flour the whole time. Sanemi thinks (shit-heads!). Tanjiro thinks (nice smell.). Tanjiro goes every time I came back, I smelled Matcha and Ohagi, so I figured. Giyu goes Shinazugawa... You like Ohagi?

Tanjiro thinks (I think he's going to punch me. So I'm activing the Kaio-ken. Goku did warn me.). Sanemi goes Ohagi's delicious! Do you like crushed or coarse beans? I loved my Grandma's Ohagi, and... He goes to punch Tanjiro who moves out of the way with red aura. Sanemi thinks (not that technique again?). As he moves in a manages to punch Tanjiro. Who's gone of guard from a bit of pain from using the Kaio-ken since he hasn't used it for ages. Sanemi angrily leaves.

A bit later on Tanjiro wakes up. And goes huh? Wha? Giyu-San! Giyu goes Shinazugawa stormed off in rage somewhere. Tanjiro goes oh, okay... Why were you fighting? Giyu goes it's not a fight. It's part of Pillar Training. Every Pillar takes part in each other's training. Tanjiro goes oh I see... Oh, so that's why. They were wooden swords... Oh, okay, okay. Sorry for getting in your way. Giyu goes that's not true. I couldn't have a good talk with him, and he was mad the whole time. But I'm glad I figured out what he likes. Next time, I'll sneak some Ohagi into a bag and give it to Shinazugawa-San when I see him. Tanjiro goes ohh! That's a great idea. Giyu goes I think we can get along for sure if I do that. While smiling. Tanjiro goes I'll do that too!

'Someone please stop them. They'll just in a fight.'

Not that far away from the place Nezuko's hiding at. Evil Goku appears and is waiting on a tree. Hiding all of his power. But he senses something. He thinks (wait! I sense Evil Nezuko! But I have to stay here on my mission.).

Goku wakes up and goes oh shit! I sense Evil Nezuko! He quickly uses Instant Transmission and appears in front of her. Evil Nezuko goes before I try to kill you. Evil You has also returned. Goku goes fuck! Well I might as get you out of the way!

With Sanemi:

He thinks (dammit. The hell is up with that guy. Seriously the brat's messed up in the head.). He hears a rustling noise. He swings his arm and grabs what the thing is. It's an eye with four in it. Sanemi goes the fuck is this?

With Goku:

Goku comes listen you! I don't have time to deal with you! I have more important matters to deal with! Evil Nezuko goes let me guess? Cell? Goku goes correct! Also Turles. Goku teleports to Ubuyashiki's place.

Evil Goku rushes in and swipes the cure for Nezuko and destroys it. He turns and sees Evil Nezuko. He goes I'm not going to let you absorb! This Nezuko! She's required for Fu's plans!

Goku goes Amane, Kiriya, Hinaki! It's time for me to take you lot to safety. They all go right. Goku teleports himself and them to where Nezuko's hiding. Goku goes huh? Shit Evil Nezuko and Me! At least their against each other. As he returns to Ubuyashiki. By sensing Muzan's energy.

Ubuyashiki goes hey, so you're here. Nice to meet you. Muzan Kibutsuji. Muzan goes well, you sure look horrible, Ubuyashiki.

A distance not that far away. Cell thinks (it's almost the time for me to attack. Right after the explosion happens.).

Ubuyashiki goes you finally came to my home... Right in front of me. Muzan Kibutsuji. The demon... My family... The demon hunters have been chasing for a thousand years... Have been chasing for a thousand years... Goku thinks (a thousand years? That's a long time. I know Hit has been around that long.). Ubuyashiki goes Goku! What form? What shape does this man have?

Goku goes he looks like a man in his late twenties. But his eyes are plum red. And his pupils are vertical like a cat's. And he as pale skin. Ubuyashiki goes oh... Okay... I... Though you'd come... For sure... I'm sure you're extremely mad at the Ubuyashiki family... But that's also why... I... was the only one... who thought you'd come to kill me yourself.

Muzan goes I'm truly disappointed, Ubuyashiki. And you, Goku why are you holding back from attacking me? Goku goes it's because enemies from my dimension are mostly the big issue. Like Turles, Cell, Evil version of me and an Evil Version of Future Nezuko. Since they all have the power to destroy the Universe. Muzan goes fair point. I need Earth to live on. Also, Ubuyashiki I've lived a thousand years without showing signs of aging. And the old family who's gotten in my way all now reduced to this. Repulsive. Utterly repulsive. You already smell like a corpse, Ubuyashiki's.

Back at Evil Goku vs Evil Nezuko:

E Goku goes how are you able to keep up with me? E Nezuko goes I trained a lot and eaten a lot of people. And I may have been able to absorb like three other Nezuko's. E Goku goes so that's it, huh? Well it's not enough! Especially since I got back the form I lost! E Nezuko goes well I can't wait to use my technique against you. Wait? Oh are we so far away from the place? E Goku goes to not kill those people! I don't want Fu to punish the hell out of me!

Back with Ubuyashiki, Muzan and Goku:

Ubuyashiki manages to turn and goes I figured... as much... I... was told by the doctors... half a year ago... that I was going to die in a few days... Yet here I am... still... alive... and the doctors... were at a loss for words... and I solely... dedicated my soul to defeating you... Muzan...

Goku thinks (the fight between Evil me and Evil Nezuko is really heating up. I don't know how she's keeping up?). Muzan goes and your fleeting dream will go to waste tonight. I will kill you right now. Ubuyashiki goes you... might not know this, but... You and I... are the same blood... you were born... a thousand years ago... So maybe your blood is different from mine...

Muzan goes I feel no emotion here. What are you trying to say? Ubuyashiki goes a monster like you... Came out of this family and that led my family to be cursed... Every child born in our family was weak, and they died right away... But when our family was about to get wiped from existence, the priest gave us some advice... A demon came from your bloodline... So you must dedicate your soul to defeating him and if you do that, your family will not die out. We have received wives from the priests for generations. And our children are more resilient to death now... But nobody in our family has lived beyond thirty... And there not here since Goku took them to a safe place.

Muzan goes and now you're reduced to ramblings. It's utterly disgusting. Did that sickness get into your brain? That is no consequence to me. After all, the heavens are not punishing me. Despite the hundreds, thousands of humans I've been let off the hook. And I never seen a god or Buddha over these thousand years. Also, Goku. Goku goes I know that you have Turles ready to attack me!

Ubuyashiki goes so that's what you think... But I have my own ideas about that... Muzan... What is your dream? This puzzles Muzan a bit. Ubuyashiki goes it's been thousands of years... What kind... of dreams do you have exactly? Goku thinks (the battle between Evil me and Evil Nezuko is now getting a bit out of hand!).

Muzan thinks (I feel strange. The head of the Demon Hunters, an absolute eyesore to me, is right in front of me, yet I feel no hatred. In fact, number one, one night passes oh so busy, busy put decorations up on the pine, on the pine number two, the leafed pine colours, colours the three fold pine is mount Kazusa, Mount Kazusa this strange nostalgia... The sense of relief... Is repulsive. There was four humans here in the mansion. Goku took three to safety. So it's only Ubuyashiki and Goku here. But no guards... I have Turles ready to attack Goku.).

Ubuyashiki goes how about I make a guess... Muzan. I understand your heart and soul. You dream of eternity... You dream of being indestructible. Muzan goes exactly. And it will come true very soon. Once I get my hands on Nezuko. Ubuyashiki goes your dream won't come true, Muzan.

Muzan goes you seem pretty confident in Nezuko's hiding place. But unlike you, I have a lot of time on my hands. Ubuyashiki goes you... are misunderstanding something. Muzan goes about what? Ubuyashiki goes I know something... about eternity. It is nothing but human thoughts. Thoughts last for eternity. They are indestructible.

Muzan goes this is foolish... You're talking utter nonsense. Ubuyashiki goes the Demon Hunters have never died out for a thousand years. True, a lot of unfortunate children have died, but they haven't disappeared at all. You just said... The truth is dumb. Let me prove to you that human thoughts are indestructible. The thought of 'never forgiving those who have taken thet lives of people's loved ones away' senselessly' is eternal. And you have never been forgiven. Not even once over the last thousand years. And you, Muzan, have stepped on the tiger's tail countless times. So you are incurring the wrath of the dragon. In essence, you have basically awoken a sleeping creature that's been slumbering for a long time. And they absolutely despise you. They will never let you get away. If you kill me, the demon hunters won't feel pain or even an itch. They honestly don't really need me that much. This connection to human thought is something you probably can't understand, Muzan. Because you... and your kind will cease to exist once you die, right? A change in the air... Am I right? Goku thinks (that's not true. Because of Future Nezuko. Wait! Could it be that demons without Muzan's curse and the connection link to him fully destroyed don't die when Muzan does?).

Muzan goes zip it. Ubuyashiki goes yeah, I'm done. I've said what I wanted to say to you. But can I say one last thing? I said honestly didn't need me that much... But that doesn't mean my death won't be inconsequential. I am fortunately, yet undeservedly, loved by my Demon Hunters... My Pillars in particular. So if I die, the morale of the Demon Hunters will be higher than ever...

Muzan goes you done talking? Ubuyashiki goes yes... Though I didn't expect you to actually listen to me... Thank you, Muzan.

Crows are going EMERGENCY SUMMON! EMERGENCY SUMMON! ATTACK ON THE UBUYASHIKI ESTATE... ATTACK ON THE UBUYASHIKI ESTATE!

Everyone is running towards the Estate. Sanemi running thinks (Oyakata-Sama!). Iguro thinks (quickly! Hurry up!). Mitsuri thinks (Oyakata-Sama!). Muichiro is also running fast. Same with Shinobu. Giyu and Tanjiro. Tanjiro thinks (come on make it!).

The Battle between Evil Goku and Evil Nezuko:

E Goku has gone Super Saiyan Two. Evil Nezuko has gone into her full morphed form. Clashing blow to blow. E Goku goes that's it! Has he goes Super Saiyan Five! E Nezuko closes her eyes. He charges in and she side steps him and kicks in the back. She turns around and opens her eyes and has a heated aura surrounding her. E Goku goes no! Not Ultra Instinct! E Nezuko goes give up! E Goku laughs and goes Kiao-Ken times Ten! And I'm no longer holding back! He charges in and they both end up going back and forth.

Earlier before the attack:

Sanemi goes we should have at least two Pillars Guarding Oyakata-Sama at minimum. Can't you do something about this Himejima-San? Himejima goes impossible... I became a Pillar when I was nineteen, and I have been asking him for eight straight years, but he refuses to budge... He insists that someone as strong as a Pillar shouldn't be wasted on the likes of him... It's a problem.

Shinobu goes I heard that the heads of the Ubuyashiki family have never even had a bodyguard throughout history...

Back at the time of the attack:

Sanemi is running and thinking (Oyakata-Sama, Oyakata-Sama! I see it! The mansion! It's okay. I'll make it. I'll make...).

All of a sudden the mansion blows up. Everyone looks on in shock. Tanjiro with his hand over his mouth thinks (an explosion! And this smell! A lot of burning blood and flesh!).

Muzan is healing and thinks (Ubuyashikiiii! That man's face! He had the smile of a Buddha. But then he and Goku blew themselves up! I made a mistake. I judged Ubuyashiki to be a normal human, but he was actually a complete nut job. Same with Goku. Wait! Goku survived?).

Goku charges right at Turles. But a beam ends up missing the both of them. Goku turns around and goes Cell!

Muzan's thinking (I figured he was planning something, but not of this scale. He made the explosion even more deadly by adding spike traps into it. Just to delay my regeneration. Which means there's still something coming. Ubuyashiki still has something up his sleeve after this. There are human presences coming closer. Most likely Pillars. But that's not all. There's something different. That shit head used himself as a decoy. His hatred and anger toward me were like a viper. It was coiling in that dead, black stomach of his. I'm in awe at how stunningly he hid his murderous intent. His wife and kids were aware of his plans. Which is why Goku took them to safety. Whatever. It's not worth thinking about it now. Don't panic. Your body will regenerate very soon. And Turles is taking care of Goku. But who else has, shown up?).

Goku goes Cell! I knew that you were going to attack me after that explosion. You may have hidden your Ki. But not your colour. Cell goes well, well. It seems like I have two Saiyans to kill how fun.

Meanwhile:

Evil Goku and Evil Nezuko are still clashing. But E Goku falls to the ground badly injured in base. He thinks (dammit Super Saiyan Five Kiao-Ken times ten. As well done me in! But I think I'm lucky.). E Nezuko falls to the ground out of Ultra Instant and her morphed form. She thinks (dammit! I been in Ultra Instant to long. I'm not going to be able to go back into it for a very long time.). They both try to get up. They both end up leaving to heal and restore their energy. By using a device.

Back at the main battles:

Turles goes what do you mean? By killing two Saiyans? Were both under orders from Fu! Cell goes like I care about him. Getting rid of you, Turles is like an extra bonus. Turles goes but Kakarot is mine! I was here first! Long before you! Cell while laughing goes and so far you have failed twice! Goku goes really? It's now more of an argument than fighting.

On the ground:

Muzan sees some round things. He thinks (Flesh Seed, Blood Demon Technique!). Muzan ends up getting impaled by a lot of long spikes that have extra spikes all around. Making harder to escape.

Muzan thinks (I've been immobilised. Someone's using a Blood Demon Technique. The spikes are branching into my flesh so I can't pull them out. No. No problem. This isn't too bad. Just absorb them, and you'll be fine.). Muzan ends up shocked. He sees Tamayo with her hand in his stomach.

Muzan goes Tamayo! Why are you here... He thinks (These Blood Demon Spikes belonged to the man who turned into a demon in Asakusa. She got close to me using a smokescreen Demon Technique. What's her goal? What did she do? Why this woman-). Tamayo goes you absorbed my fist, Muzan. Do you have any idea what's inside it? A drug to turn demons back into humans. So? Is it working?

Muzan goes you shouldn't be able to... Tamayo goes oh, but I've done it! The situation's completely changed. Though it would have been impossible for me alone. Muzan goes you are one stubborn woman, Tamayo. And your hatred towards me is unjust. Who killed your husband and kids? Was it me? Not at all. Nobody but you. You ate them all up.

Goku heard what was said and thinks (man! I didn't know that about, Tamayo.). As he avoids a punch.

Tamayo goes if I knew that would happen, I wouldn't have become a demon! All I wanted was to not die from my disease! I just wanted to see my kids grow up! Muzan goes then you killed a whole bunch of humans after that all an illusion too? I noticed you had a lot of fun eating those humans. Tamayo goes that's right. I killed many people after falling into the depths of despair. So to pay for my sins, you and I are dying right here! As Muzan puts one of his fingers in Tamayo's right eye.

Tamayo goes Himejima-San! Do it, please! Himejima comes in swinging his spiky Nirchin Mace. He goes Namuami Dabutsu. With tears in his eyes. With one blow! Muzan's head is smashed.

Goku ends up landing a blow on Cell. Cell goes is that all you got? Pathetic! I expected more from you Goku. Heck! Even Turles is above you. Goku goes Cell! I'll show you my Power! As he goes straight into Mystic. Turles goes I'm going to enjoy killing you both! As he goes into Super Saiyan Four with his Full morphed demon form. Cell goes okay then.

Turles tries to land an attack on Goku. Who dodges but hits kicked hard by Cell. Who also punched Turles away. Goku goes alright then! Full Power! Goku charges in and Cell avoids the attack but then ends up with a punch to his stomach. Cell goes wow, Goku! You actually managed to hurt me. But seriously if that's you're full power. Then you're so dea— As Turles lands a blow right in Cell's face. But missed Goku with a kick. Goku flies back and fires multiple Ki blasts.

Gohan Black, Goku Black, Emily Son, Nezuko Son, and Bardock all sense the battle and rush off towards it.

TBC

(A/N): Well I did say at the start of the battles. But I don't know how many chapters this story is going to end in. Also I am working on some sequels.

Also I just want to get this out there. Any other crossover with Goku in Kimetsu No Yaiba. Goku teenager and above has to be nerfed so they don't be overpowered. I hate it when people complain about me nerfing Goku. On Wattpad I read a fanfiction with Teen Gohan in Demon Slayer. I saw that in the comments people wanting Gohan nerfed.

Like seriously not nerfing Goku is lazy writing. Since he can just go straight up to Muzan and instantly kill him without trying when not nerfed. Goku is too busy fighting his own enemies in this story. If Goku gets to beaten up and exhausted by his own enemies. He then can have trouble fighting the demons.

I'm not evil. At least I didn't kill off Amane, Kiriya and Hinaki! Sadly I can't save everyone. Some are still going to be killed off sadly.

Now unfortunately bad news. My health aren't good. I so far had 19 seizures/fits. And I'm waiting for my MRI results. So there's going to be a hiatus. I hate health issues. Like doesn't everyone hate health issues.

Oh and stay safe. Wash hands, wear a mask or a face shield and keep your distance. Let's try and beat the virus!

Sadly other stories production are also going to stop. So anyone here who reads Demon Slayer Z. Sorry but that's also going to be on hiatus. Until I'm well enough to continue. I will upload a health update. So Dragon No Yaiba Z is also going to be delayed. The first two chapters are ready. But chapter 3 is nowhere near ready at all it's like 1/3rd through.

Next time the battles continue. Gohan Black, Goku Black, Emily Son, Nezuko Son and Bardock all engage Cell to help Goku. All the Slayers vs Muzan and the remaining Upper Moons.
