"I ain't takin' no chances this time," James said to Mukago as he loaded up his shotgun and the wounds he made on his arms to create ammunition from his blood fully healed up. "I'll be carryin' my sword and my shotgun tonight as my main arms, alongside my revolver as my sidearm, of course." He then finished loading the shotgun and then checked the revolver, spinning the cylinder around and checking each chamber to make sure all six were fully loaded with poisoned ammunition. "We're goin' in hostile territory tonight. The minute we both step back into Yoshiwara, we'll be targeted by those fuckers Jubal Early brought along, so we gotta move fast and we gotta strike hard when we reach the Kyogoku House. Who knows how many fuckin' soldiers they got around the entire Red Light District lookin' for us?"

"I didn't want to have to do this," Mukago said to him as she loaded her revolver and began loading up two speedloaders she also carried. "But Daki-senpai has left me no choice. If she won't see the light, we'll have to kill her and her brother. I'm hoping she realizes she's being used and abused by Muzan before it's too late."

They then both heard a commotion downstairs as Hirohiko shouted, "Hey, hey, hey, put the fucking guns down! What do you guys want?!"

They then heard a voice in heavily accented Japanese demand from him, "James Colby and traitor! Where are they?! Where they?! Tell us! Where?! Where?!"

"I don't know where they are?! Who the fuck are you guys talking about?! You're saying a bunch of damn nonsense and shit! Get the fuck out of here! Get out! Get the fuck out!"

"Tell! Tell us! No talk! Tell!"

"Put the fucking guns down and get out, damn it!"

An English voice with a deep southern accent then said, "This fucker ain't gonna talk to us, Billy. Why don't we just kill 'em and have 'em as a meal? I mean, for Christ's sake, we're wastin' our time with this shit."

"We gotta go," Mukago said to James as they both rushed downstairs. As they did, Mukago saw two men in Confederate uniforms facing Hirohiko with rifles. "Hey! Get away from him! It's me and Colby-san you want, assholes!"

"There they are," said one of the soldiers in English as he pointed at her and James. "Get 'em! Shoot the fuckers!"

James quickly pulled out his shotgun from behind his back and got two shots off before the Confederate soldiers could fire at him, striking both down immediately and splintering the wooden floor behind and beneath them. "Got 'em!"

"Agh, fuckin' Christ! Come on, get up!"

"Hang on now!" As they both went down screaming in pain from the poisoned ammunition, James ran up to the first one and told him in a sinister tone in English as he jammed the hot barrel of the shotgun into his mouth, "The only one that's being shot here is you, motherfucker." He then pulled the trigger again and blew the soldier's head off, with pieces of his skull and flesh flying everywhere as his body began to fade from the poison and the blood that coated the area around him began to evaporate.

"Fuck you!" The second soldier then stumbled to his feet and drew a knife, but he was deflected by Mukago, who then drew her sword and silently decapitated him, killing him as well.

Mukago said as she sheathed her sword, "Two down, who knows how many to go."

As the second soldier fell to the ground and began to disappear, Hirohiko told them both, "You guys better move fast! If we don't kill that Upper Moon and those other American Moons tonight, we'll all be dead by tomorrow!"

"We ain't gon' let that happen," James assured him as he reloaded his shotgun. He then slung his shotgun back over his shoulder and ran out the door. "We'll see you soon, Hori-san!"

Mukago also told him, "If we need help, we'll send for you! Otherwise, stay here if any of those bastards come back to get you!"

"On it," Hirohiko replied. "I'll show those fuckers a good fight if they come along!"

…

In the Kyogoku House, the male overseer was reading over paperwork by himself while also inspecting Omitsu's bloodied clothes, trying and ultimately failing to take his mind off of the recent events that had happened at the brothel when he suddenly felt a presence behind him. "Huh?"

"Tell me where Hinatsuru is," Tengen then demanded of him in a calm but very firm voice as he held a knife against his neck. "This isn't a request. Don't even think about asking any questions unless you tell me what happened to her."

"Hi-… Hinatsuru-san was sent to an infirmary nearby because she got sick," the overseer replied. "That's all I know. She's still alive, but I don't know about her condition… I'm sorry."

"Okay," Tengen replied as he removed the knife, knowing the overseer was lying based on his tone of voice. "Look, you can trust me. It's my job to take care of things like this. Tell me everything that you think could be relevant to all this. I'll find whoever did this to Omitsu-san and kill them. You have my word that I'll deliver justice."

"Omitsu…" The man began to tear up as he remembered the events that led up to her untimely demise at the hands of Daki and Jubal. "I know who it was. It was multiple people, all led by the oiran Warabihime and this foreigner man from America named Early. I think his full name was Jubal Early or something like that. They killed Omitsu. That bitch and that damn foreigner took her from us. I think they both went out to do something. They didn't tell me anything."

"Very well."

Just as quickly as Tengen appeared, he disappeared as the man wiped his eyes and began to collect himself emotionally. "Huh… Where did… Where the Hell did he go?"

…

Meanwhile, Jubal and George were both meeting with Muzan in a darkened alleyway to deliver a report to him about the status of Daki and Gyutaro. "So," Muzan asked the two of them in English. "What do you have for me?"

"We know for a fact that there are at least a few demon slayers runnin' around in Yoshiwara," Jubal replied. "One of 'em killed Tommy, and we know exactly who it was."

"Let me guess. It was that hunter from America, wasn't it? Mr. James Colby…"

"Indeed, sir," Jubal replied, confirming with a nod. "Mr. Colby definitely killed Tommy. There ain't no doubt about it. In other news, Daki and Gyutaro have been growin' more and more… How do you say… Well, contemptuous of our presence. They've really been gettin' on my nerves and dismissive of me."

"So they are… I've always seen Daki as an annoying child, and her reaction to my assignment of you two plus your lost friend has only confirmed my suspicions." He then sighed. "Truth be told, I've always had problems with them, though Gyutaro is by far the best of the two. I like him, actually. If that idiot slayer magnet of a sister of his wasn't around, I'd like him even more. She thinks she's so special to me, but the truth is, she's way too gullible and tries too hard to embrace the cruelty to humans needed to be an Upper Moon. All she does is copy whatever she sees those above her doing and saying, and it's really annoying. I can easily dispose of her if I really wanted to."

"What do you propose we do?"

"Simple," Muzan replied with a grin as he snapped his fingers, which caused a red light to briefly surround him before fading away. "With that finger snap, I've severed the life link between the two siblings so now Daki can be killed independently of Gyutaro once he leaves her body. They won't notice a thing until she's dead. If Gyutaro doesn't like that, I'll make him like it one way or another."

George then asked Muzan, "And what do you require from us and our soldiers?"

"All I require is that every slayer inside Yoshiwara be killed by the end of tonight," Muzan instructed the two of them. "Especially that Mr. Colby character and, if my senses are correct, that rogue demon Nezuko and her brother. I want those three dead above all else."

…

At the Ogimoto House, an impatient Inosuke was pacing around the room as he said to himself, "Where the fuck is everyone?! This is taking way too damn long! I can't wait for Sojiro, Monitsu, and Nezuko! I need to act now and Pig Assault my way to victory!" He then took a deep breath and jumped up into the ceiling, his head going right through the wood and into the attic. Once his head was up there, he looked around and said, "Mice! My swords! I need them!"

On cue, two oddly-formed mice began crawling towards Inosuke's head. Both were unusually muscular for their size and bore small headbands in a similar style to Tengen's own. Both had been trained to walk on their hind legs while carrying swords with their forelegs. Their muscular bodies helped them carry the swords, which were incredibly heavy for their own body size.

Inosuke remarked to himself, "Uzui, you smart bastard. These mice sure come in handy."

Within less than a minute of jumping up, Inosuke came back down and then caught his swords as they fell from the hole he had made with his head. He then ripped his kimono and undergarments off, grabbed his pants, hurriedly pulled them up, and then grabbed his trademark boar's head mask before putting it on his head and grabbing his swords. Just as he did, an older woman opened the door to his room, expecting to find Inoko, and was instead confronted with Inosuke in his normal outfit, which frightened her. "Aah! What?! No!"

"Look out," Inosuke then yelled as he barreled out of the room and down the hallway. "I'm coming through! Don't get in my way! I got demons to slay!"

…

As Tanjiro walked along the rooftops of Yoshiwara, he suddenly stopped in his tracks as a putrid scent overcame his nostrils. "Agh, damn it…" He looked around and thought to himself, "This has to be the scent of a demon! It's really strong too!" He then slid down off the roof and to the ground, landing on his feet. As he did, he looked down the alleyway and found Mukago running towards him. "Huh? Mukago?!"

"Tanjiro!" Mukago then caught up to him. "Me and Colby-san split up. He's in Yoshiwara too. Have you found anything?!"

"I scented a demon in this area, and it wasn't you. I recognize your scent, but this one… This is unfamiliar to me…"

The two then turned to the building they were standing on the first-floor lean-to roof of. "I wonder if it's coming from here," Mukago said as she drew her sword.

"Oh no…"

"What?"

Tanjiro then began to pick up on another scent. "I smell someone else…"

"Who?!"

"It's Koinatsu-san!" He then jumped up and forced open the window of the building, shouting, "Koinatsu-sa-!" Both he and Mukago then gasped when they found what was inside the room.

"Oh my, how nice of you to drop by, demon hunter…"

Inside the room was Daki, who was holding a trembling and fearful Koinatsu hostage inside of her obi, concealing all but the top of her head and her nose inside a series of tightly-wrapped pink sashes. Tanjiro shouted, "Koinatsu-san!"

"I know there are more of you," Daki told Tanjiro. "One of your kind killed one of my associates. Granted, he wasn't a well-liked one of mine, but still. How many of you are the-?"

"Daki-senpai!"

"Huh?" Daki then looked at Mukago behind Tanjiro and asked her, "What the Hell are you doing here?!"

"Daki-senpai, listen to me! Muzan doesn't give a fuck about you! He's only using you! Do you think he actually cares about your well-being?! Fuck no, of course he doesn't! You need to stop with this bullshit and run away! I'm begging you! Please, walk away from this!"

"Shut up! You betrayed us, Mukago!" She then formed a variety of obi sashes that proceeded to blow both Tanjiro and Mukago away and into another building across the street. As they both impacted the building with a loud crash, Daki said to herself, "Damn it, why did she have to get involved in this?"

As Mukago coughed from the attack, Tanjiro slowly got up and took off the now-empty transport box he always carried and set it down on the lean-to roof of the building they had impacted. "I can't let this get destroyed."

"But your sister isn't in the box anymore," Mukago pointed out.

"I don't care," he replied. "This box carries far too many memories with my sister to be tossed away."

"Here I come!" Daki then sent several obi sashes towards the two of them, which they were prepared for.

"Breath of Water, Fourth Form: Striking Tide, Turbulent!"

"Breath of Mist, First Form: Low Clouds, Distant Haze!"

Both Tanjiro and Mukago then deflected all of the obi sashes sent their way, cutting them all in half and allowing them to fall to the ground. When an obi sash almost approached Nezuko's old transport box, Tanjiro shouted, "The box!" He then managed to strike the sash before it wrapped around the box, cutting it away with ease. "Don't touch my sister's old box! It means a lot to me!"

"Sister, huh?" Daki then crawled out of the hole she had made. "So, you're the slayer with the demon sister who's among your ranks… I must say, your eyes are rather pretty. I might just have to rip them out and eat them up when I'm done with you."

"You're God damn right," Tanjiro yelled in response. "My sister Nezuko's a slayer just like us!"

"Nezuko… Wait… You said Nezuko?!" Daki was shocked to hear the name of the girl who she thought was actually Kie coming from Tanjiro. "You didn't fucking say that! You can't be serious, right?!"

"I am! Her name is Kamado Nezuko!"

"No…" Daki then retreated slowly back into her room. "No way… No fucking way… It can't be…" She then angrily punched a hole in the wall and screamed in anger, "No fucking way! It can't be her! Kie-san can't be the traitor! No! No, no, no! What the fuck?! What the actual fuck?! No!"

As Daki screamed again in a fit of rage, Mukago said to herself, "Daki-senpai… What happened?"

Tanjiro also wondered to himself out loud, "What happened between Nezuko and Daki?"

"God damn it," Daki then shouted before turning to Tanjiro and Mukago, pointing at them and telling them, "I'm gonna kill you two later! I gotta take care of that liar Nezuko and her little friend Zenko! Stay here if you want to die painlessly and not get eaten alive!"

"Oh no, you don't!" Just as Tanjiro and Mukago slid off the lean-to roof and onto the ground, however, Daki fled from them at a breakneck pace, with neither of them being able to catch up. "Damn it," Tanjiro yelled in frustration. "We lost her!"

"But you didn't lose me, you know…"

Both Tanjiro and Mukago turned around and found Gyutaro standing behind them, having separated from Daki without either of them knowing. Mukago shouted at him, "Gyutaro-senpai!"

Tanjiro asked her, "So that's Gyutaro?!"

"Indeed I am, man…" He then formed two sickles from his hands. "So, this is what you've been up to, Mukago? I thought you were going to be an Upper Moon one day for sure under our tutelage, or at least Lower Moon One, you know? Instead, you ended up with the organization trying to kill all of us… Ironic, isn't it, man?"

"Listen to me," Mukago then told him. "You need to stop fighting us! Leave Muzan behind! Get your sister and get out of here! You can leave the past behind and start a new life!"

"Spare me the bullshit," Gyutaro warned her. "I don't give a fuck what you have to say, Mukago, not after you left us."

They all then heard Tengen shout, "There they are!"

All of them then turned to behind Tanjiro and Mukago as Tengen and Inosuke came running towards them. Gyutaro remarked in annoyance, "For fuck's sake, how many of you guys are there, man?!"

"Enough to take you out," Inosuke shouted at him. "Who the Hell are you anyway?!"

"That's Gyutaro," Mukago warned Tengen and Inosuke. "He's the other half of the Upper Moon Six spot. Those sickles in his hands are poisoned, so watch out!"

"Right you are," Gyutaro replied as he then readied himself for his first attack of the battle. "And you'll see how poisonous they are soon!"

All four then saw a barrage of flying sickles come from his hands as he threw more and more at them. Mukago shouted, "Don't let them slice you! Even one slice can kill you if it's deep enough!"

"Got it," Tengen replied as he readied himself by pulling out his swords and tossing several of his homemade bombs into the air. "Breath of Sound, First Form: Roar!" He then slammed both swords on the ground just as the bombs went off, producing a large and loud explosion, that deflected many of the sickles away from them. "Now this is gonna be a flashy battle!"

As Tanjiro and Inosuke both began deflecting sickles with their swords, Mukago made a small cut on her arm and declared, "Blood Demon Art: Snowy Mist, Extension!" As the blood spilled from her cut dissipated, a cold and blinding mist engulfed the air around them, ultimately enveloping the whole block in a whiteout. She had used a larger and more powerful form of her Blood Demon Art, but it came at the cost of having to actually injure herself temporarily.

Gyutaro, now unable to see his targets, said to Mukago, "Well, well, looks like your hiding abilities are paying off… But you can't hide forever!" The battle of Yoshiwara had now begun, and as Tengen had predicted, it would go down in Demon Slayer Corps history, if not Japanese history in general.
