Last time Goku and Tanjiro passed the final selection and the z fighters need to get Goku back for the tournament of power which is like a month away.

Chapter 4

In the Dragon Ball Universe

Bulma has finished the dimensional time travelling machine. But before they can use it they need to know the name of the dimension and time zone that Goku is in. Whis comes back with good news and bad news from the time nest. Everyone asks for the good news first, Whis says that Goku is a live and well and that the dimension is called Kimetsu No Yaiba and that Goku is in the Tashio period like 1917.

Everyone and the bad news Towa and Mira have but up a negative energy field blocking us off away way to get Goku back so Towa and Mira have to be defeated which isn't easy.

The Kimetsu No Yaiba Universe:

Goku and Tanjiro are making it back to Urokodaki's place from from the final selection. Goku is part carrying a wounded Tanjiro on his back but their uniforms are part heavy but this does not bothered him at all. Has they got back the sun has set and they see Urokodaki's door kicked down with Nezuko walking out side Tanjiro is surprised and happy to see Nezuko wake Tanjiro gets off Goku's back and tries to run to Nezuko but falls over Nezuko runs and hugs her brother and Goku decides to join in the hug. Urokodaki sees them hugging and hugs them and says you both came back alive while crying under this mask.

Goku decides to teach Nezuko his martial arts and give her some battle experience so she has less chance of being injured in battle to part save some energy, Tanjiro and Urokodaki both agree to this. Urokodaki and Tanjiro agree with Goku about not to teaching Nezuko the kaio-ken encase she goes berserk and the fact that she will require more sleep since the kaio-ken part burns energy.

Goku has also part done some extra training with Tanjiro this allows Goku to use Kaio-ken times 4 for like 2.5 to 4 minutes and kaio-ken time 3 for like 7 to 10 minutes and kaio-ken times 2 for like 12.5 to 15 minutes. Tanjiro can now access kaio-ken times 2 for like 3 minutes now. Urokodaki started to make a box for Tanjiro to carry Nezuko in and Goku of course helps him make the box.

15 days later

Goku and Tanjiro hear windchimes coming closer to the Building the Man stops and says my name is Haganezuka and I have forged Tanjiro Kamado's and Son Goku's swords and I am here to deliver them. Tanjiro says I am Tanjiro Kamado and Goku says yo I am Son Goku, both say please come inside. Then Haganezuka says these are Nichirin swords and I forged them. Tanjiro goes please come in so we can serve you some tea. But the guy continues the materials for a Nichirin sword can be obtained from the mountain closest to the sun. Scarlet Crimson Ore. These produce steel that can absorb sunlight. Tanjiro says wow, is that right? Goku in his mind (man is guy is rude he isn't paying attention to us), Mt. Yoko is bathed in sunlight all day, you see, oh he paying some attention to us. Never a cloud in the sky nor any rain. Urokodaki goes there he goes again, never listening to what others say. You're going to get dirty, so could you get up for a second?

Haganezuka then looks at Tanjiro and he's like a clown mask? Hey you're a Child of brightness, aren't you? Now that's what I call lucky. Oh no, I'm the son of Tanjuro and Kie. That's not what I meant. See how your hair and eyes are a reddish colour? When a kid like you is born into a family that works with fire it's considered lucky and a cause for a celebration. Is that right? I had no idea. There's a good chance that this sword will turn red! Right Urokodaki? Yeah.

Then Haganezuka puts his attention on Goku and says hmm muscles, strange spiky hair and black eyes don't know what colour your sword might turn and Goku says well there's only one way to find out.

Come on, hurry up and draw it! Nichirin Swords are also known as "Colour Changing Swords." They change colour depending on the bearer. Tanjiro draws his sword first and looks at it while it turns jet black. Black? It's black, huh? Ok Goku draw your sword. Ok after drawing it the sword colour chances to blue, red and yellow patterned lines. Oh that's new we haven't seen three different colours on 1 sword before.

Goku says oh the three colours are of my Super Saiyan, Super Saiyan god and Super Saiyan blue transformations. Which puzzles Tanjiro, Urokodaki and Haganezuka. They ask him what he means and he explains how he was able to turn into those forms before ending up here.

All three of them said so your an alien? I guess you can say that yes but my race evolved differently to yours but both are still technically monkeys. They also ask how old are you actually Goku say well I am meant to be 48 years old with my body being 41 years old because I was dead for 8 years and spent 1 year in the hyperbolic time chamber but I know I was turned back into a 16 year old but I have grown back into a 18 year old at least.

All 3 of them are quite until Tanjiro says wait you have been dead for a total of 8 years how are you alive. Goku says well the first time I was bought back with the Dragon Balls and the second time I was revived by the old kai. One last question what are dragon balls? Well there are seven of them and once all collected a magic wishing dragon called Shenron who can grant any wish within this power. Sadly I think that he hasn't got enough power for me to be returned to my Universe. But hopefully my friend Bulma will find a way by building a Machine to travel here and get me.

Them everyone turned to Tanjiro's black sword. What is it bad or something if it turns black? Is it unlucky? No, not necessarily. But you don't see this pitch black too often. And I was so hoping I'd get to see a bright red sword! Dammit! Goku goes relax I have a bit of red in my sword while Haganezuka is hurting Tanjiro. Who says please calm down! How old do you think you are?! I'm thirty-seven!

Just then two crows fly through the window and land and both say Tanjiro Kamado and Son Goku here are your orders! Tanjiro it talks, Goku well I have already seen talking cats and birds in my universe. Both of you'ves make your way to a town to the northwest! Young girls have been vanishing there!

At night in the town a young boy and girl are walking together and then the girls disappears. Night after night young girls have been vanishing! Hunt down the demon lurking there and kill it! Tanjiro Kamado and Son Goku, prepare yourselves well for this task! This is both your first assignment as Demon hunters! Oh our first assignment, Goku says I hope it's a strong demon since I like fighting strong opponents, Urokodaki says it doesn't matter if its weak or not you have to kill it since it's now your job. Ok them come on Tanjiro let's get our uniforms on. Goku I think it's better to go early in the morning after we have eaten and rested. Oh hey food and Goku please leave some for everyone else.

In the morning after Breakfast Tanjiro and Goku are both getting dressed into their demon slayer uniforms has Tanjiro puts his kimono on over his uniform and Goku puts on a new kimono that looks like his old orange clothes other his uniform. Urokodaki says oh you both have gotten changed? Yes both replied. Nezuko under the sheets moves and looks out of the slightly open door and part gasps at both Tanjiro and Goku's appearances.

Urokodaki says Tanjiro and Goku now that you both are starting out with the Demon Slayer Corps I'd like to explain a few things to both of you. Ok. That Demon Slayer Corps outfit you're both wearing right now. It's made of a special kind of fibre. The fabric is quite breathable, yet it repels moisture and won't burn easily. A low-level demon's talons or fangs couldn't even manage to tear that uniform. Tanjiro says it's that strong? Also both your Nichirin Swords colours varies from owner to owner and each hue has unique properties. But Tanjiro not many people end up with black blades, little is known about them. So little in fact. So little is known that... What Mr. Urokodaki? Since so little is known about them black blades are said to be wielded by swordsmen who'll never go far.

I don't know how I'll do in the Demon Slayer Corps, but I'm going to turn Nezuko back into a human no matter what. Goku says Tanjiro not just you I am going to try and help you I promise. Yes, you're both right. I have faith that you'll both are going to make that happen. Oh and Goku a sword like yours has never been seen before. One more thing. Take this. It's a box for you to carry your sister in during the day. It's built out of an extremely light wood called "Cloud Mist Pine." I coated it with rock lacquer to reinforce its exterior and to make it more durable. Plus Goku here part helped me make it. Thank you very much you two! It's so light! It's really light, Mr. Urokodaki!

Nezuko, get inside this, will you? Can you do it? Nezuko makes herself smaller and fits perfectly in the box. Tanjiro says Nezuko, from now on, we're always gonna be together, okay? Goku says sheesh Tanjiro you almost sounded like a kidnapper. All right, we'll be going now. Hold on, do you mind? Has Urokodaki buttons up the top of both of their uniforms. Tanjiro and Goku both wave goodbye to Urokodaki and start making there way to the village.

On the way there Tanjiro asks Goku why he eats so much food and Goku says well the stronger a saiyan gets the more we have to eat which is the reason why I have so much a big appetite.

Tanjiro goes Nezuko, are you all right? Nezuko? Flashback "I'm just guessing here, but it could be that Nezuko's recovering her strength by sleeping instead of consuming human flesh (end of Flashback). Nezuko You get lots of rest.

Oh look we have arrived at a town. So could this be the town to the northwest? It must be and its massive with so many people like a small city. A beaten young man is slowly walking through the town. Some other locals go oh, look, there's Kazumi. Poor thing, he looks so haggard. Because he was with Satoko when she was taken. Tanjiro and Goku both stop and look at him and walk on a little bit. The people say night after night... It's so creepy. It's so dreadful! When night falls, yet another young girl will be abducted! Tanjiro and Goku after hearing that turn around and run towards Kazumi. Mr. Kazumi! He turns around hear hearing his name. Tanjiro then asks if you don't mind, we would like to hear your story. Is that all right?

Kazumi takes Goku and Tanjiro to a location and says this is where Satoko vanished. You both may not believe me. Goku and Tanjiro at the same time say we do believe you! We believe you, alright! We believe you. Before Tanjiro starts to try and smell out the demon he asks Goku if he a sense the enemy or see its aura. Sorry there isn't enough aura for me to track and I can't sense the demons ki until its active. Tanjiro starts to try and smell out the demon.

There's still a faint trace of the demon scent, but it's uneven, so to speak. Well Tanjiro I think it's just better to wait for it to be activate so I can sense it and we can engage it easier. I think I agree with you there Goku so let's rest a bit and move during the night. Who are these kids anyway? Kazumi touches his wound on this face and thinks about the beating he was given (how dare you! What do you mean, "vanished"? You bastard! Dear! That's enough! Please stop!). Okay Kazumi we are going to continue the search at night. He asks why, because they're are only active at night so me and Goku.

At the start of sunset Goku and Tanjiro go outside and Kazumi goes I want you both to believe me. She really did vanish. We believe you. After all, that's why we both are here. So you're both gonna to keep going? Yes. It's so late now. I'm flattered that you both are so concerned for me, but shouldn't you guys pick up tomorrow since it's not safe. Has we said those things are only active during the night and we can't afford to rest.

I have detected a new scent in this area. Goku well the it's now active follow me Tanjiro right let's go. Those things... Don't tell me you both are. You're both seriously... Goku nods yes in response.

While in a house in the town. How terrifying. I want you to stay indoors for the time being. Yes mother. Now then, good night. A young girl is going to bed and something appears on the floor and starts moving after the girl. The girl says I wonder what became of the girls who were taken. I just hope they're all right. All a sudden a solid like liquid spreads around the girls bed and hands comes out of the solid liquid and grabs onto the girl covering her mouth and pulls her down into the weird liquid.

Goku senses a ki die down and Tanjiro picks up a new scene and both run off. Kazumi ask what's gotten in you two all of a sudden? So fast. The scent got stronger and the Ki a bigger! Both the demon's at large! Tanjiro and Goku both jump onto a roof with Goku almost over jumping it. They jumped? They spoke of demons. The Demon Slayer Corps... They really... Goku and Tanjiro stop and look around and Goku shouts below us. Okay so they are right here right now.

They both draw out their swords. Two different scents, two different ki's. A demon and a female human! They're nowhere to be seen. Tanjiro I said below us, oh your right. But I have to hit the spot where the scent is the strongest... Is right here! He stabs the ground and a puddle appears and he part sees some clothing reaches in a successfully grabs and pulls the girl out.

A morphed demon!

Flashback to Urokodaki saying the demons who use a special spell called the "Blood Demon Art" posses supernatural abilities. You both have to fight those demons, as well, from now on.

Back to the Battlefield:

Where are those girls you kidnapped? But the demon grinds his teeth. I have two more questions for you! Kazumi says who was that? Mr. Kazumi, please hold this person and stand nearby. If you're inside both our range of attack we can protect you! From the ground or this wall... It could possibly emerge from anywhere else. There is also the chance that it might be able to show up out of thin air.

But this demon... Even when it's submerged, it can't erase its scent! Hmm it can't hide its ki when submerged. Here it comes Water Breathing, Fifth form! There's four of them! Oh man four of the same demon Goku thought. As Tanjiro manages to avoid all four of them. Settle down, I can do this. Eighth form Waterfall Basin!

Another Flashback:

Tanjiro, Goku listen to me closely. The type of demon with the blood that can turn humans into demons... There's only one in this world. Just one. The one who was the first to become a demon more than thousand years ago. In other words, that is your family's foe. Moreover, I believe he's the one who might know how to turn your sister back into a human. That demon's name is Muzan Kibutsuji!

Back to the battle:

Eighth form Waterfall Basin! Tanjiro has cut one arm off all four demons. Too shallow! I missed all the vulnerable spots because I switched forms midway through! Goku comes in and says I take care of the 4th version of the demon since its the strongest of the lot. I hope you can handle the other three. OK Goku I will try and handle the other three.

All 4 go back into their swamp so all four of them have the same scent and Goku says he will handle the strongest one. But we told that demons don't band together as a rule. So this one demon has dispersed into four. So I have to protect these two while slashing three of them has Goku handles the 4th. So I can't lose my nerve! Make sure that I get him to me about Muzan Kibutsuji and how to turn a demon back into a human! Total concentration Water Breathing second form Water Wheel! Too shallow again! Tanjiro tries to hit the demon and misses multiple times.

Dammit I can't chase him to far and I can't take a full swings while guarding others! The demon shouts you bastard. Back off for crying out loud! That girl's gonna go stale on me, dammit! That girl's already 16, okay? If I don't devour her soon she's gonna lose flavour by the second! The other part of the demon appears and says clam down my other self. Hey, so what? There are gonna be nights like this and where is my 4th self.

Meanwhile Goku is fighting the 4th version of the demon and its just a one sided battle in Goku's favour he says your too weak I will just end you now and get back to Tanjiro. Goku easily cuts the demon's head off killing it with no effort at all and starts making his way back to Tanjiro.

Anyway I've already fed on plenty of 16-year-old girls in this town. They were all quite meaty and delicious. Well I'm not satisfied my other self! I wanna consume more! Kazumi says you monster, return Satoko to me. The one you abducted the night before last. They look up and see the demon grinding his teeth on a roof. Satoko? Who are you talking about? If her hairpin is among these collectibles then I have devoured her. Tanjiro starts seeing bad stuff versions of his family dieing and screaming and seeing there dead bodies with an image of, Nezuko with blood fully covering it up. Which Trigger's him the demon tries to hit him and missed has Tanjiro dodged and slashed the demon's arm off. Ha I missed again. He can escape underground so fast. Oh no! I got too close to the wall! And dodges with a jump. The demon got Tanjiro off guard and was about to hit Tanjiro in the face but Nezuko came out of the box kicking the demon away saving her brother.

The other demon says why would two humans be accompanying a demon? What's the meaning of this? And who are these two and the other guy? Are they swordsmen and a demon working together? I don't get it at all. Nezuko steps out of the box and looks at the enemy demon she kicked away. Goku came back to see Tanjiro and Nezuko face the three demons and decides to watch to see how Tanjiro and Nezuko get on with the Extra training he given to both of them.

The demons returned to their swamp and Nezuko turns and looks at Kazumi and the girl and starts to see then has family while touching them. Then she turns the direction the two demons resurface. Short Flashback Urokodaki this may only be cold comfort but while Nezuko was asleep I used hypnotic suggestion on her. Suggestion? "All humans are your family." "Protect humans." "The demons are the enemy"! Back to the battle, Nezuko runs after the demons. Nezuko, shouts Tanjiro. "Never forgive any demon who brings harm on humans"! Has Nezuko goes in for a kick at the demon and misses has the demons go back into their swamp. Tanjiro shouts Nezuko and she stops, don't chase after him. Get back here. Come to me. Nezuko he shouts has the demon tries to get the jump on her. Nezuko jumps over the demon and Goku says to himself did she just do a superhero landing pose like I seem on TV.

Tanjiro in his head goes Mr. Urokodaki did tell me that Nezuko is a demon now plus that Goku did some training with her and that she's not necessarily so weak that I have to protect and I just remembered at I can dsuppressedo that kaio-ken technique that Goku taught me. But is it alright to let her handle this? Plus what is Goku doing? If I have her watch over those two, I can focus on my attacks.

The swamp opens under Tanjiro and tries to attack Nezuko who dodges the attack. Nezuko, Nezuko I'm going underground! Goku thinks I can't watch him while he's under at least I can watch Nezuko. Tanjiro to Nezuko I want you to protect those two. You can do that right? She nods yes. Tanjiro goes into the swamp has Nezuko and the other demon starts fighting. In the swamp Tanjiro sees leftover clothes of people eaten. So these are the clothes and belongings of the people who were kidnapped? Just look at all the innocent people they're murdered! It's unforgivable! Unforgiveable.

The demon laughs and says getting hard to breathe, brat? There's hardly any air inside this swamp. On top of that the darkness coiling around your body must feel pretty heavy? You can't move the way you would above ground! Serves you right! You should have looked before you leaped in, you damn fool! Both demons start attacking Tanjiro who takes notice mostly because of the demon grinding his teeth give it away. Tanjiro thinks don't underestimate me! Just where do you think I got my training anyway? The air was thinner on top of Mt. Sagiri! Not to mention there are moves that only unleash their full potential underwater! Plus I can double it with the kaio-ken thanks to Goku. So they can move at angles like that inside this swamp? But it doesn't matter.

All I have to do is slash when they get near enough to attack. The form that can be utilised even when there's no sure footing. Generating a powerful vortex with a violent twist of my upper and lower body. Here comes the scent the opening thread. Suppressed kaio-ken times 1.5 and Total concentration Water Breathing sixth form Whirlpool. Both demons are cut to shreds and killed. Tanjiro quickly sees and grabs the clothing with the girls hairpin in it and notices that he's running out of air and has to get out fast.

Back with Nezuko fighting the other demon are part going back and forth by part dodging and blocking each other's attacks. Until Nezuko lands a punch in the demon's stomach. The demon in his head goes this girl is powerful. While being kicked away. She doesn't seem to have mastered any morphing skills yet but look how strong she is anyway! She must have gotten a huge amount of blood from him! She moves so fast I can't dive back into the swamp. But I am getting use to these one-note attacks of hers. Nezuko notices the enemy demon adapting and she starts to use the martial arts that Goku taught her. Even if she kicks my head clean off or even if my internal organs explode demons can regenerate in a flash. The swamp demon attacks and thinks he got Nezuko off guard but ended up getting pinned to the floor instead. What who taught her martial arts.

Tanjiro appears from the swamp and sees Nezuko pinning the demon down. Nezuko release I have him at sword point and I want to ask him a question. Did I just get taken out? Both of my other selves got taken out by this guy and the other taken out by the other guy. You give off a scent like rotten oil. It's a horrible smell! How many people have you killed? He's killed to many shouted Goku. Listen, if women live any longer, they turn ugly and start tasting like crap. So we killed them for their own good. You should be thankful to us demons. Tanjiro cuts the demons mouth and says never mind and backs the demon into the wall. You're going to tell me what you know about Muzan Kibutsuji.

The swamp demon ends up in fear. Talk to me! Start talking. Tanjiro I think you might be going a bit too far says Goku his aura has turned into fear. I can't tell you, I can't tell you, I can't tell you, I can't tell you said the demon. Flashback of Muzan talking to the guy going to be turned into the swamp demon and said you mustn't tell. You mustn't tell anyone about me. If you do tell anyone, I'll know right away. I'm always watching you end of flashback. I can't tell you, I can't tell you, I can't tell you, I can't tell you! The smell of fear is strong. He is trembling all the way down to his bones! I can't tell you alright? And makes the mistake of trying to attack just to lose his head and die.

Once again I failed to get any information. Nezuko is just asleep regaining energy without any injuries. Goku says good thing I taught Nezuko most of my martial arts or that demon would have wounded her. Goku why did you mostly watch instead of further helping? While getting Nezuko back in the box on this back. Sorry, I am sorry Nezuko that you had to fight at least you didn't get hurt. Goku answers I just wanted to see how you both get on especially after the extra training I give to both of you and I am proud of the results. Tanjiro says to Nezuko I promise to turn you back into a human! Goku says I also promise that well at least until someone can take me home. Also just think that we were lucky that Towa and Mira haven't got involved or we would have been in so much trouble.

Tanjiro asks Goku who Tora and Mira are and he replies my saying they are demons from my universe who want to kill me so I don't stand in their way and they are the reason I can't transform, fly or use instant transmission and why I am trapped in your universe. I have to hide my ki so they can't find me because we will all die if they find us. I might be able to go Super Saiyan when I get angry enough.

In the Dragon Ball Universe:

Towa and Mira are angry dam Goku he is so good at hiding his ki that we can't find him. Plus the others are trying to find away through our barrier blocking them off from getting to Goku.

Vegeta dammit we must find a way pass that barrier. Gohan says well don't we just have to find Towa and Mira and weaken them enough to get passed the Barrier to get my dad back. Well then we better find those two quickly and try to make sure they actually die so they can't kill anymore versions of me and kakarot. While Gohan and Vegeta are looking for Towa and Mira. Whis is managing to watch Goku in the Kimetsu No Yaiba universe.

Kimetsu No Yaiba Universe:

Mr. Kazumi? Are you all right? I've lost my fiancée. How can I be alright? Mr. Kazumi no matter how many people you may lose you have no choice but to go on living. No matter how devastating the blows may be. What do you know about it? A kid like you? Tanjiro grabs Kazumi hand and shows a fake smile gets up and says I'll be on my way now same here said Goku. Take this I hope you'll find something of Miss Satoko's in there. Kazumi opens the fabric and starts crying when he sees Satoko's hairpin. Tanjiro bows and starts walking away with Goku. Kazumi thoughs so, you went through the same thing, too? Is that it? I... I'm sorry! That was an awful thing to say! Please forgive me! I'm so sorry! Goku though he said sorry enough times. Tanjiro turns around and waves good bye. His hand was heart-breaking to see. Hardened by relentless training and so thick. It wasn't a boy's hand. I am leaving that young woman in your hands! Alright, alright.

Tanjiro and Goku leaving the town and Tanjiro thinks to himself it's not just me. How many people have you killed and tortured and tormented? Muzan Kibutsuji I'll never forgive you as long as I live. Just then a crow land on Tanjiro's shoulder and one on Goku's shoulder. The crows say Next up, Asakusa Tokyo! Rumours of a demon lurking there! We are heading to our next mission already? Oh yes, you both are! Hold on a minute. No can do! Come on just give us a minute! Hold on! What? Just shut up and go already. Goku says well we better get going then I am ready apart from being so hungry. Tanjiro says when are you not hungry? Well I can't help it.

Tanjiro and Goku arrive that Asakusa Tokyo. A very shocked Tanjiro with Nezuko at this side says are the cities this advanced now? It's a nightmare, but it's so bright out! The buildings are so tall! Goku says you should see the cities in my universe they are more advanced and have even taller buildings. Tanjiro just didn't know how to respond to what Goku said. Goku also thought how has no one noticed or the bamboo muzzle on Nezuko's mouth or my spiky hair which doesn't fit in here? Tanjiro and Nezuko stop when a tram passes in front of then which just confused Tanjiro a bit more. But this doesn't affect Goku at all.

I feel dizzy. Uh, let's go that way Nezuko. I-I beg your pardon! When he sees two people kissing in a valley. Tanjiro, Nezuko and Goku all run to a part of town where they come across a Udon food stand. Excuse me I would like a bowl of Udon with grated yam on top please and Goku says two bowls please. Uh, sure thing!

I've never been to a place like this. While Goku kind of as. It's way too crowded. Nezuko asleep ends up a Tanjiro's shoulder and Goku says boi you two have a really strong bond I and can tell from both of your auras. Here's your udon with grated yam on top and here's your two bowls Goku eats his food so fast that the man is shocked and happy at Goku. But has Tanjiro started his he picked up a smell and ran towards it leaving Nezuko on the bench along with his food on the floor with the bowl smashed and Goku noticed this and ran after Tanjiro. He caught up with him has Tanjiro came in contact with Muzan Kibutsuji. Goku saw Muzans aura and is shocked he thinks that bastard has killed so people I want to kill him now but I can't do it in public.

Tanjiro and Goku are shocked to find out that Muzan is pretending to live has a human. Muzan says to the little girl he's holding it's alright they don't worry. Goku and Tanjiro are both thinking he's. He living here, pretending to be a human! Muzan asks is there something I can do for you two? You both seem quite flustered. A woman comes and says oh my. What's going on? The little girl says mother. Tanjiro puts his own hands on this mouth and stomach and goes in his head they're humans! The girl and the woman... Their scent is human. Goku the girl and the womans aura and ki are human but what are these other two strange auras and ki's I see and sense. Don't you know? Can't you tell? That guy is a demon? That he devours humans? The woman asks do you know them? No. Much to my consternation, I've never seen this child and young man before.

Unfortunately for Muzan, Goku notices his nails. They must have mistaken me for someone else. Oh, you think so? Goku caught Muzan slash a random person's neck mostly because Muzan doesn't know that Goku can see speeds up to the speed of light with his eyes. But Tanjiro also notices the back of the man's neck bleeding.

Dear, what's the matter? As the man is turned into a demon and attacks this wife. Tanjiro runs out saying stop! Goku secretly charges a small ki blast and fires it Muzan who is stunned by that and said what hit me? Has Goku tried to keep his face straight while Tanjiro is pinning the newly formed demon on the floor. After everyone who said what's this? What's going on? I-is that blood?

Muzan notices the hanafuda earrings that Tanjiro is wearing and finds that the that the other guy somehow hit him with no being near him. Dear the woman shouts. Ma'ma you need to worry about yourself! Please take a cloth and press down hard on the wound! It's alright somehow, it's going to turn out fine. The woman's wound isn't fatal! Do it harder! Do it harder, tie it up with a rope! Goku man if only I had sensu beans on me. It's going to be alright. This man hasn't killed anyone. Just a second ago, this man was just walking down this street.

The girl in Muzan's starts to get scared and Muzan asks are you alright? You mustn't look. It's dangerous here, Rie. Let's move over there. Where'd he go? Dammit, dammit I can't leave this man here wait Goku try to secretly follow him. Okay says Goku following Muzan while staying out of sight. Has Tanjiro shouts Muzan Kibutsuji I'm not letting you get away. No matter where you go, Goku can track your ki. What's the matter with that child? What do you think Tsukihiko? Muzan isn't happy. Tanjiro continues no matter where you go you're not getting away. No he isn't Goku said to himself. I'll follow you to the ends of hell and I will swear I'll slice off your head with my blade. I'll never forgive you no matter what. Dammit Goku said I did lose him dammit I might has well go back to Nezuko who we lefted on the bench.

Police what the hell are you doing? Is it a drunk? Kid step away from that man! I can't bring some restraints please! While Goku got back to the bench and sat down a tried to have a small nap with Nezuko awake and confused wondering where her brother is. Nezuko your brother is just fine he be back in a bit. Back with Tanjiro please. Shut up and step away! Please don't do that. No one can here can hold down this person but me. Move. Please don't do that. Just look at this guy's face! Has he lost his mind? Pull the kid off him! Please stop. I don't want this person to kill anyone! Just stay out of the way, will you? I'm begging you! Dammit! Look, you if you're going to keep resisting... All of a sudden, a flowery attack caused by a demon using enchanting blood. Aroma of Visual Fantasy. What's this scent? Ok now what's with this new ki energy. What are all these patterns? What's going on? I can't see anything! Is this some kind of attack? If it is, that means trouble! Is the scent growing stronger? A woman walks up to Tanjiro and says you still use the term "person" to refer to even a transformed demon and you're trying to save him. Allow me then to lend you a hand. But why? Tanjiro asked as Goku reappeared. You, your scent tells me that's right I am a demon, but I am also a doctor and I wish to annihilate that man, Kibutsuji. A doctor uh has Goku enters the spell with a ki barrier shocking them.

Meanwhile with Muzan.

The little girl asks aren't you coming Daddy? Daddy had work I have a business meeting to attend. I'm also concerned about that disturbance just now. Dear... Don't worry I'm only going to talk to the police. Now get in. Daddy come home soon okay? Alright. You be a good girl now. Take them back to the house. Go on. Muzan starts walking down an ally way three people are walking the other way and one is drunk. Big bro, let's hit one more bar! Yacchan are you okay? I'm fine, I'm fine. I'm not even drunk yet. But bumps into muzan. What the hell, you bastard? Forgive me Muzan said. Hey come back here.

I'm very sorry, but I happen to be in a hurry, so. What did you say? Hey, look at you, decked out on those posh-looking threads! You piss me off! You and your pale face you look like you're about to fall over dead. This Trigger's Muzan. Hey, say something, will you? Or did you just croak? Muzan kills the man in one punch. Yacchan! What did you do to my kid brother? Yacchan! He's dead! Yacchan's not breathing! You bastard the other man said. Muzan kills him in one kick.

He goes up to the woman and asks does my complexion look unhealthy to you? Is my face pale? Do I look sickly to you? Do I look like I'm not long for this world? Do I look like I'm about to die? Wrong, wrong, wrong, wrong. I'm a living being who's infinitely close to perfection. Muzan puts his finger into the woman's head and starts but so much blood into her and he says what do you think will happen if I keep flooding you with my blood? The human body is unable to withstand the speed of transformation and its cells are destroyed and the woman turns into a puddle of blood.

Goku goes Tanjiro yes Goku what is it? I just sense 3 ki's disappear and I think Muzan had something to do with it. Back Muzan on the alleyway. Muzan clicks his fingers and to demons show up. Bring me the head of the demon slayer who wears hanafuda-like earrings and another demon slayer with strange spiky hair, understood? As you wish. Your wish is our command.

Author notes:

Dam I made this chapter so long. I am going to take a break since this chapter is like three times bigger than I would normally do.

Also, Merry Christmas and a happy new year. Also next chapter would possibly be roundabout late January.

Plus what do you think of Goku's sword being Red, Blue and Yellow lines being in form with Super Saiyan, Super Saiyan god and Super Saiyan Blue?
