Last time Tanjiro, Inosuke, Zenitsu and Goku have gotten aboard the Infinite Train. Shinobu and Goku Black have both arrived at their mission. And Goku awoken Nezuko's memories which makes her human side more in control of her demon side which makes her more mature and smarter.

Chapter 9: Start of Missions:

Goku, Tanjiro, Inosuke and Zenitsu all have gone inside the train from entering the back and start looking for Rengoku. But Inosuke goes uwo ooo ohh! We're in the belly! We're in it's belly! Whoaaa! It's the beginning of the fight! Zenitsu goes shut uuup!

Zenitsu goes this Rengoku-san"s a pillar? Do you know what he looks like? Tanjiro goes yeah, he's a guy with flashy hair. And I remember his smell. He's very close... Goku comes well I can sense him remember. They all get shocked when they hear tasty! Tasty! Tasty! Tasty! Being shouted. Goku, Tanjiro and Zenitsu all find Rengoku eating and going Tasty! Tasty! Tasty! And continues. Zenitsu goes that guy's the Flame Pillar? Tanjiro goes yup. Zenitsu goes isn't he just a glutton? Yup.

Tanjiro goes uhh... Excuse me... Rengoku-San... Rengoku is still going tasty! He looks at Tanjiro and goes tasty! Tanjiro goes ah I understand very well already. Goku says remember how much I eat.

Tanjiro explains the Hinokami Kagura Dance to Rengoku. To maids are taking away all of the trays Rengoku has gone through and are part struggling. Goku helps them out by carrying the bag with all of the trays. Rengoku goes hm! So that's it! But I dunno! This is the first time I heard of the 'Dance of the Fire God'! I'm actually delighted to see that you were able to apply the dance your father performed in a fight, but enough of this story! Goku comes back in and listens to their conversation. Tanjiro goes huh? Could I have a little more... Rengoku says you should become my Tsuguko! I'll look after you!

Tanjiro goes please wait! And where are you looking? Rengoku goes the Breath of Flames has a long history! Inosuke is looking out of the window and Zenitsu thinks (What a weird guy.). Rengoku goes Swordsmen who can use flames and water have become Pillars in every age, no exceptions. The basic breaths are Flames, Water, Wind, Rock and Lightning. And the other breaths are branched out from those. Mist is derived from the Wind! Young Mizoguchi, what colour is your blade! Tanjiro goes I'm Kamado and it's black. Rengoku goes black! That's tough! Is it tough? While laughing. He continues by saying I've never seen a swordsman with a black blade become a pillar! What's more, I understand that you don't even know what kinda swordsmanship to master!

Inosuke has this head out of the window and goes uwoooohh! Wow! Wow! It's so faaast! I'm gonna get out and run! I'm gonna have a race to see which one of us is faster! Zenitsu goes that's dangerous. Moron! There are limits to idiocy!

Rengoku goes it's dangerous! I don't know when the demon's gonna appear! Zenitsu goes you're kidding. A demon's gonna appear on this train? Rengoku goes it will! Zenitsu goes it will? Noooooooo! So we're not going to a place with demons, but one's gonna show up here? Noooooooo! I'm getting off! Goku says Zenitsu please clam down and stop with the screaming your not the only one with super hearing! Zenitsu goes sorry I try not to scream. Rengoku goes in a short period of time, more than 40 people have disappeared on this train! We sent a number of swordsmen here, but none of them ever reported back! So that's why I'm here as a Pillar! Zenitsu goes haaaaah, I see! I'm getting off! Goku goes wait how is everyone else asleep? Especially with how loud Zenitsu is being! Tanjiro goes hey Goku's right. Rengoku goes wow everyone is asleep how did that happen?

A guy comes up and says I will look at your tickets. Tanjiro goes what's that? Rengoku says the conductor is coming around to confirm your tickets and punch holes in them. The guy punches the tickets. Zenitsu is going get me offfff! Tanjiro goes (hm? What's this? I smell something bad!). Goku also goes (why do I smell something bad?). The conductor goes I have seen them... Rengoku gets up and goes conductor! It's dangerous so stand down! It's an emergency. So I would prefer it if you don't ask me why I have a sword on me! Goku says well conductor you really look like your in need of sleep.

A demon appears and Goku goes oh so those people are awake never mind. Rengoku goes big guy! Were you hiding your blood demon techniques? It was hard to find your presence however! If you're baring your fangs at sinless people the Red Flame Sword of Rengoku will burn you down to the bone! Rengoku rushes the demon and goes Breath of Flames First Style Sea of Fire! He has successfully cut the demons head off and the demon dies. Tanjiro goes that was awesome Aniki! That was amazing swordsmanship! Make me your disciple! Goku goes I thought I am your current teacher! Tanjiro says well you are. Goku goes well i actually think that's it's a good idea for you to train with someone you can catch up with. Since you can never catch up to me!

Rengoku goes sure thing! I'll make you into a fine swordsman! Zenitsu and Inosuke both go me too! Goku goes I might has well I do need to improve my sword skills. Rengoku goes I'll look after every single one of you! Tanjiro, Inosuke and Zenitsu all go Rengoku Anikii! Anikii! All of a sudden everyone is asleep.

With Shinobu and Goku Black:

Shinobu goes so some people from the Village have been frozen to death I think I might know the demon! Kakarot! Black says I also think that I know the demon because it's probably one of the one's who ambushed me. Upper Moon Demon two wasn't it? Shinobu goes the demon that took my sister away from me! Black goes sorry to hear that. But I do want revenge since he is part of the reason I was turned into a demon. And I never wanted to become one. Had he removes his protective clothing and mask. They walk past some dead part eaten frozen bodies and they come across a temple. Black goes I sense bad energy in there. Hmm let's go in.

They enter the temple and they see lots of dead eaten bodies. Black tries to contain his demon instincts and not go after the bodies. Black manages to control himself besides the mass amount of hunger and pain. Black thinks (Well being in a Saiyan body and being a demon is hard since both normally are super hungry). Shinobu goes up there it's him Upper Demon Moon Two! Upper two goes more prey. Wait is that the Demon traitor? Black goes before we fight what's your name? Upper two says my name is Douma. Now Muzan wants you captured so he can deal with you, personally Kakarot Black!

Douma goes wait I recognise those clothes your wearing girl. Shinobu goes don't talk to me! Douma goes wow why are you angry at me? Shinobu goes because you're the Bastard who killed my sister! Black goes enough chat! Let's get him! Black charges Douma and Douma goes you fool has he unleashes ice and traps black in ice or that's what he thinks. Black goes sorry but trying to freeze me isn't going to work. Black thinks (I got to kill him before he can release another attack.). Black goes Kaio-ken times three and instantly swings his sword and chops Douma's head off. Douma goes how? You haven't eaten any humans. Black says I was already leagues above you before I became a demon and not by choice. Douma has finally disappeared. Shinobu goes my sister has finally been avenged.

Back on the Train:

Lower Moon Demon one is standing on top of the train. He says being able to die while dreaming is a blessing.

The conductor goes I did as I was told, I punched their tickets and put them to sleep. Please put me to sleep quickly. Please let me meet my dead wife and daughter. Please, please. A hand with a mouth goes sure thing. You did a great job. Now sleep. And have a good dream where you can meet your family. The conductor ends up asleep on the floor. A young girl goes umm... What about us... The hand says just wait here and you'll get sleepier very soon. The sharp witted Demon Hunters might wake up because they'll sense the demons and their thirst for blood. Be careful as to not touch their bodies when you get close and fasten the cord. I cannot move from the locomotive for a while. Just do your best until everything's prepared. So you can have a wonderful dream. All the people say okay!

Lower One goes it doesn't matter how strong the Demon Hunters are. The driving force of human beings is the heart. The soul. I should just destroy the 'core of the spirit'. If I do that, they'll be living corpses. And it'll be easy to kill them. All human hearts are the same. They're brittle and weak. As if they're made of glass.

Everyone Tanjiro, Inosuke, Zenitsu, Rengoku and Goku are asleep. Zenitsu is dreaming about being with Nezuko. Zenitsu in his dream goes here! Here! The peaches here are delicious! And there's a lotta white clovers blossoming here to. I'm gonna make a flower wreath of white clovers and give it to you, Nezuko-Chan! I can make them really well! Nezuko goes sure, make lot of them! Zenitsu goes there's a river along the way, but it's shallow, so is it alright? Nezuko goes a river? Zenitsu-San, what can I do? I can't swim. Zenitsu goes I'll carry you and we can jump! It's a river! Nezuko-Chan, I won't let the tips of your toes get wet! Leave it to me!

Inosuke's dream:

He goes explorers! Explorers! We're the cave exploring brigade! He hears boss, boss! He goes what's up. Minions one and two! Ponjirou (after a raccoon) goes I smell the Master of this cave from over there Ponpoko! Chuuitsu (after a squirrel) goes I can also hear his snores Chuu! Inosuke goes okay here we go! It's Showtime! Now come. Minion three! Come on! Over here dammit! I'll give you some shiny acorns! Let's go! Everyone else goes yeah!

Rengoku's dream:

He's sat down next to his father. Rengoku thinks (hm? What did I come here for? Oh yeah, I'm reporting to my father that I have became a Pillar.). His father says so what if you become a Pillar. This is pointless none of this matters. We won't ever become great people anyways. Both you and me. Rengoku walks away. He hears ah. Big brother. Was father happy about it? When I become a Pillar, maybe dad will acknowledge me too.

Rengoku thinks (he wasn't like this long ago. My dad became a pillar of the Demon Hunters. He was a man full of passion. But one day, he suddenly gave up on the sword suddenly. He was a man who raised us so passionately. But why even when I mull over it, I just think it was inevitable. And Senjurou is in an even sadder situation. He pretty much doesn't have any memories of our mom, who passed away from sickness before he gained his senses, and our dad is now in this situation.). He goes down and says I'll be honest. Our father isn't happy. He said it was pointless. But! My passion won't die because of that! The flames in my heart will never disappear! I'll never be disheartened! And you're different from me Senjurou! You have an older brother and he believes in his younger brother. No matter what path you take, you'll be a wonderful person! With a burning passion in your heart. Senjurou is crying. Do your best! Do your best to live! Even if you get lonely! They are hugging.

Goku's dream:

Hey Chichi. She goes what is it now? Goku says I am just going to take Goten fishing is that alright. While wearing and carrying fishing gear. Same with Goten. Chichi goes yes you both can go fishing and bond. She thinks (I can't believe that they are bonding while fishing.). Goku thinks (wait a minute I am not at home I am on a train in another Dimension! I now sense the demon.). Goten goes come on dad the fish aren't going to catch themselves. Goku says coming. They arrive at a river and Goku puts bait on the fishing rod and throws it in and waits. Goku decides to go into the water and catch fish by hand. Goten takes control of the fishing rod. Goku sees this reflection and sees himself wearing a black uniform with a sword. The reflection comes up too Goku and grabs hold of him and says wake up it's a trap. Goku goes but I don't know how to make up because I can't. Wait might have to kill myself here to make up. But I don't have my sword. Wait I can just use a Ki blade. I hope this works. Wait before I do that I will why and telepathically go into Tanjiro's dream and try to help him first.

At the same time Tanjiro's dream:

Tanjiro is dreaming about being home with his family. He arrives back to be welcomed by his younger brother Shigeru and sister Hanako. Shigeru goes Nii-chan welcome back! Did you sell charcoal? Goku wakes up and find himself in Tanjiro's dream at the point he actually arrived. Goku goes (okay I am here I wait for Tanjiro to notice this isn't real first before I engage.). Goku sees Tanjiro hugging Shigeru and Hanako and that Tanjiro's crying. Tanjiro goes waaaahh aah aaah! He also goes sorry! Sorry! I'm sorry! Shigeru and Hanako and both confused. Tanjiro is crying in his sleep. But no knows that Goku has managed to enter Tanjiro's dream.

The other people on the train. One of them goes so we fasten the arms with rope? Another one goes yeah. Don't forget about the warning he gave. They all have tied rope to Tanjiro's, Zenitsu's, Inosuke's, Rengoku's and Goku's arms. One of the people goes just breathe deeply and count some numbers. If you do you'll fall asleep. They all go (one, two, three, four, five, six, sev.). They have all gone asleep.

Back to Tanjiro's/Goku's joint dream:

Hanako goes so, we were surprised since Nii-chan suddenly started crying. Takeo goes he's weird, aha ha. Tanjiro's mother Kie goes well... You might just be tired Tanjiro. Just rest today, and don't push yourself too hard. Tanjiro goes you're just exaggerating I'm fine! She goes are you sure? He goes yeah. It felt like I was having some sorta bad dream. Shigeru puts a sheet over Tanjiro going baaa-fuuun! Tanjiro goes uwah! What're you doing! Aaaghhh! Hanako goes stop it! I just washed that! They hear a knock on the door. Kie opens the door and Goku goes excuse me I seem to be a bit lost so can I stay here a bit? Kie goes sure come in. Goku walks in. Tanjiro sees him and goes you seem to be familiar. Hanako goes how we just met him.

In the train Lower Moon One goes have a nice sleep. Forget how to breathe. Do the demons will reap. Your bellies from underneath. It's fun. Isn't it? They began having happy dreams. They're sleeping deeply and can't wake up anymore. Wait how is the guy with spiky hair gotten out of this dream into the one with the hanafuda-like earrings dream? Oh well it doesn't matter.

The ropes created by the Sleep Demon Enmu, have a special power which enables people to penetrate the dreams of those connected to them. But how does this work with Goku telepathically being in Tanjiro's dream.

In Rengoku's dream:

The girl enters Rengoku's dream. She goes (whoa, the 'real body' is there.). She sees Rengoku with his younger brother. She thinks (I have to make sure he doesn't notice me.). She starts running. (Quickly to the 'edge of the dream'...).

Information about the dream:

The dream the Sleep Demon Enmu shows you doesn't stretch to infinity. The dreamer ends up in the center of a circle. There is an area of unconsciousness outside of the dream. The 'spiritual core' lies in the unconsciousness area. If this is destroyed, it's owner will become mentally crippled.

Back to the girl in Rengoku's dream:

She goes (there it is. It's the 'wall'. The scenery keeps going but it doesn't go any further than this. I'm just gonna quickly destroy this 'spiritual core' so I can have a sweet dream as well.) She breaks through the fence. She goes (this one weird 'unconsciousness area'. It's hot. I'm burning up. Found it the 'spiritual core'! It's the first time I saw a red one. But his 'spiritual core' is brittle, so I can easily destroy it. Like it's made of glass.). She goes !? Kagh!

In the real world Rengoku has grab the girl by the throat. But Rengoku moved when he was trapped in a technique which shouldn't allow him to move. The girl who entered his dream didn't give off a thirst for blood. But Rengoku's body sensed her presence through his Instinct. If his 'spiritual core' was destroyed, he would become incapable of battle. Which means he would be unable to fight. The girl can't move because she is suffering in the real world. And Rengoku cannot move any further because he has no reason to kill humans. The two of them are now caught in a deadlock.

Tanjiro's and Goku's dream:

Tanjiro goes huh? Where's Nezuko? Takeo says onee-chan went out to get some plants. Tanjiro goes huh? In the afternoon!? Everyone is puzzled. Hanako goes is that bad? Tanjiro goes ah, no... huh? Kie goes Tanjiro could you prepare the bath? This might take some time. Tanjiro goes ah, sure. I got it, I'll do it now. Goku goes I might has well help. Kie says that's so kind of you. Hmm. Goku goes oh my name is Goku. Kie goes well Goku I like the part you're helping us out.

Tanjiro and Goku both go outside. Tanjiro thinks (I keep saying weird things. Maybe I'm tired.). Tanjiro and Goku both look and see a box in the distance. Tanjiro goes whoa. Has he accidentally knocks over the bucket. Tanjiro goes (huh, it disappeared. What the heck was that? Was there a toolbox. A moment ago? Did my eyes deceive me?). Goku goes so you have seem the box too? Tanjiro goes oh so it wasn't just me. Goku thinks (he has trouble recognising Nezuko's box in this dream but he remembers me.). They arrive at the Tanjiro bends out to get water in the bucket. There. Tanjiro is about to get some water and he sees his reflection but the reflection looks different. Tanjiro puts the bucket in the water and gets pulled under. A Tanjiro in the water goes get up! They're attacking! A dream! This is a dream! Wake up! Get up and fight! Tanjiro dragged under goes oh yeah, I see, I'm on a train!

Tanjiro closes his eyes and tries to wake up and Goku tries the same thing. They both end up back in the house. Tanjiro is between Shigeru and Hanako. Shigeru goes Nii-chan gimme the pickled radish. Hanako goes you can't! Stop it! Why're you taking Onii-chan's food like that! He goes what!

Tanjiro thinks oh no, I'm in a dream I can't wake up from. What can I do to get out!? And I finally realised this is a dream. What can I do!). Goku thinks (well the only way I guess is to kill ourselves in the dream in wake up in the real world. Not sure how Tanjiro would like that.).

On the Train Nezuko gets out of her box, and falls onto the floor. She looks up and sees a Rengoku holding a girl by the neck. Nezuko thinks (okay what did I miss and why is that guy holding that girl by the neck.). She goes up to Tanjiro who's saying I have to wake up... It's a dream... I have to get up...

Nezuko goes up to him and thinks (what to do, what can I do? Wait I could try and help him with my demon blood art!). Nezuko puts her hands on Tanjiro and starts using her demon blood art.

In the Dream Tanjiro is surrounded by flames. Goku thinks (well that's definitely Nezuko's demon blood art there!).

Hanako goes Onii-chan! Takeo goes what do we do about the fire! They both shout Nii-chan! Tanjiro goes (it smells like Nezuko. It's Nezuko's blood. He sees a image of Nezuko with her hand out. Nezuko!

Tanjiro's appearance has changed. He goes (my uniform! My Nichirin Blade! I'm waking up! Little... By little! Hanako goes Onii-chan are you okay? Takeo goes Onii-chan. Tanjiro says sorry I have to go. Goku appears and says yes we do! Hanako and Takeo are puzzled. Tanjiro and Goku both say we both have to go back now. We're sorry. Everyone one shouts Onii-chan, Goku!

Tanjiro thinks (now... a demon is showing me this dream and he's nearby! I have to find a way to kill him now!). Nezuko appears and says where are you going. Onii-chan? And who is this? Tanjiro is stumped. Nezuko says I got a lot of vegetables today. Kie appears. Tanjiro goes ah, Mom, Rokuta. Kie goes Tanjiro what's wrong? Why do you look like that... Tanjiro thinks (I wanna stay here forever. I wanna turn back and head home. If this was real, I would just stay here like this forever. If this was real everyone would be happy now. Nezuko could also be under the blue sky, in the light of the Sun. If this was real, if this was real! I would've just come here to burn some coal today. I would've never touched a sword before. But I still might have met Goku. If it was real... If it was real! But I've lost them already! I can't go back!)

Tanjiro runs off and Goku follows him. Tanjiro goes (sorry Rokuta. We can't be together anymore

But your big brother always thinks about you. He thinks about all of you. I think about saying thank you a lot, I think about saying sorry a lot, I will never ever forget you all. You will always be next my heart. So please forgive me.

The guy in Tanjiro's dream goes (I have to destroy their spiritual cores quickly.). Another man goes (I must destroy their spiritual cores before it's to late.). Both guys are together and think (this is so beautiful. It's just infinitely vast. It's so warm...).

In Inosuke's unconsciousness area. A girl thinks (where's the spiritual core... What's with this weird unconsciousness... That disgusting naked boar...). All of a sudden Inosuke with an actual pig head appears and attacks her. Kyaaaaahh! She shouts why're you in your unconsciousness! Gyaaaaahh!

In Zenitsu's unconsciousness:

The guy thinks (it's so dark I can't see anything. Dammit. What's with that blond brat's unconsciousness? Do I seriously have to fumble around for his 'spiritual core'? God dammit come on... It's hard to breathe and my body feels heavy. It's like everything's been completely smeared with ink.). Shnip! Is heard. He goes (what the!? What's that sound!? Is it getting closer!?). Zenitsu appears behind him with gardening shears. Zenitsu says why did a guy come in here? You shitty vermin. The only one who can come in here is Nezuko-chan. I'll kill you.

Nobody should be in the unconsciousness area, but basically there are cases when people with a strong consciousness will manifest in their own unconsciousness area.

Back with Tanjiro and Goku:

Tanjiro is going hah, hah. Not here. (There are no demons here. But I smell them. Faintly... But what is this... It's like there's a curtain here. I smell demons from everywhere. I can't pinpoint a particular place. He says I have to hurry! Nezuko's blood is, flowing in me. If everyone else is sleeping we're in a really bad situation. Goku goes listen to me! We have to kill ourselves to wake up! Tanjiro goes right! Anyway how are you barely affected. Goku says well it's because in one dimension someone trapped me in a mind trap and I had to fight a version of myself. I was saved by Naturo! Yes him. I was also trained against mind tricks after that. Which is why the dream state barely affects me. Tanjiro goes but how would you know that it would wake us up. Goku says to be honest I read it in a magna that I saw my son Goten reading. Tanjiro goes Manga? Goku says well. I know I shouldn't be here really. But Fu has plans on killing me so I don't stand in his way, like I did before.

Enmu goes they're having trouble. I wonder what happened. Maybe they still haven't destroyed someone's 'spiritual core' yet. Well they're buying some time, so it's okay. Goku goes okay I sense demons and I can't see any. Tanjiro says Goku there are no demons in here. Tanjiro thinks (I can use my permanent full focus breaths right? So I'm just sleeping right now! A, figure appears behind Tanjiro and says Tanjiro you have your sword. There is something here for you to cut down already. Goku goes hmm. (I guess that was Tanjiro's father.).

Tanjiro's appearance was reflected on the water's surface, Nezuko's box, and his father's words when he appeared behind him, this was all a warning from Tanjiro's own Instinct. Tanjiro couldn't understand the 'small clues' which he should have noticed already, so Tanjiro's consciousness took his own form as well his father's appeared in front of him, and warned him. Also Goku keeps, hinting about him cutting his own neck. Tanjiro thinks (there is something for you to cut down'... 'some thing to cut down... So you can wake up'... I think I get it. But what if I'm wrong? If what I do in the dream affects reality, I can't recover...). He sees Goku moving his figure across his own neck. (don't hesitate do it! I'm doing it! A death in the dream' is, related to 'waking up in reality' so the thing I should cut is my own neck!). Tanjiro cuts his own neck. Goku thinks (finally he's got it.). Goku creates a Ki blade and cuts his own neck.

TBC

(A/N):

Okay so Goku had telepathically went into Tanjiro's dream. Remember Goku awoken Nezuko's memories last chapter making her behave more human and a smarter thinking. Plus Goku Black has killed Douma Upper Moon Two so I guess that the Canon is thrown out of the window there. Plus this is only Chapters 54, 55, 56 and 57 from the Manga with some changes and extras.

I have decided to make the chapters smaller now so I can make them easier and release them quickly. Along with being quicker to read.

I have also so far made multiple chapters of another story I am working on called Multiverse Danger and it involves some Dragon Ball and Kimetsu No Yaiba timelines, along with very, very small parts of Naruto, One Piece and Fairy Tale they barely have any involvement. Plus Doctor who and some other characters from some other franchises. Multiple enemies are involved too including two I made up. But sadly I can't upload that since it part contains some spoilers of future chapters from this story with a little bit of different outcomes that lead to similar things.

Oh Emily will return in a future chapter with some secrets to tell Tanjiro and Goku.

Also next chapter is going to have chapters 58, 59, 60 and 61 in it with changes and extras. Plus when I get to the battle against Upper Moon Demon Three will also have an Extra Battle which has a lot more a stake and it's not against Upper Three, it's one of Goku's old enemies. Haha.
