In the second dream level, Susamaru and James awoke in a crowded hotel lobby. They immediately nodded to each other and walked to the front desk, where they met a projection of a hotel clerk. "Good evening, sir," the clerk addressed James in English. "Are you and your wife interested in a room?"
"Indeed," James replied, pulling money out of his pocket. In the dream, he had converted the Japanese yen he carried to dollars. "We need it for just a single night. How much will that be?"
"A single night would be three dollars," the clerk replied.
"This should cover it," James replied as he handed over three dollars to him. "Here's an extra dollar as a tip."
"Why thank you," he replied. "I'll get your room key right away. Do you have a preference for a room?"
"Not particularly," James shook his head. He then turned to Susamaru and told her in Japanese, "Now we have to find Enmu."
"Where are we gonna find him?"
"He should be easy to reco-" He then looked to his right and saw the man of the hour checking in at the front desk alongside him. "There he is…"
"Well, that was easy."
James then walked up to Enmu, asking him, "Hey there. Is your name Enmu?"
"Huh?" He then looked at James with an expression of surprise on his face. "Oh, yeah, I am. Who are you?"
"You're in a lot of danger," James explained to him. "Follow me."
"Follow you?" James then began walking away to find a secluded area of the lobby, with Enmu quickly trailing behind him. "Hey, wait a minute! I need to know why I'm in danger! What's going on?!"
"I need to tell him in a place with no people," James thought to himself as he rounded a corner and entered a men's room. "If I tell him in a crowded place, the projections will look at me with suspicion."
Meanwhile, Susamaru carefully went into the women's room next door to carry out the next part of the plan, and the only part she agreed with: Pretend to be Muzan and induce Inception by suggesting Enmu to give up, so that a projection of Muzan in the next dream level would do the same. As she walked out, she had changed herself to look like Muzan's infamous female form, with her voice changing as well due to the ability to change anything about yourself in a dream. "Okay," Susamaru said to herself as Muzan. "Time to find him."
In the men's room, Enmu asked James, "Who the Hell are you?"
"I'm Mr. Charles," James explained to him. "I'm the head of security you set up."
"Head of security?"
"Not in real life," James told him. "But inside your subconscious. I'm in charge of the weaponized aspect of your subconscious, and I believe that someone is trying to infiltrate your mind. Tell me, how did you get to this hotel?"
"Well, I…" Enmu stopped as he realized he could not remember. "I don't know." Then, the room shook somewhat, startling him to a degree. "What the Hell was that?"
"You're inside a dream, Enmu," James replied. "None of this is real." He then picked up a small glass that someone had left behind in the men's room and poured water into it. As he set it down, the water inside tilted somewhat to one side before resting back in its normal position. "See that? That wouldn't be physically possible in real life. You should know, since your powers allow you to induce dreams in other people and infiltrate the dreams of others."
"Right," Enmu nodded. "I know all that."
"When you weaponized your subconscious," James once again lied to him. "You created me to lead the projections that would suppress any unwanted visitors."
Suddenly, a man armed with a pistol ran into the men's room. "Die, you piece of shit!" James replied by tackling him to the ground and disarming him of his gun as the two struggled before pulling out his own and shooting him in the chest, killing him.
"See that?" James lied to Enmu and told him that the projection that he created was actually an intruder. "That was one of the intruders. They're comin' after ya to commit Extraction." Extraction referred to the more commonly employed opposite of Inception: The infiltration of someone else's mind to steal secrets. As he handed Enmu the gun, he told him, "We can't let these fuckers win, Enmu."
Enmu took the gun and aimed it at his head, saying, "I know for a fact that if I shoot myself here, the dream will end."
"Hang on," James begged him. "Don't do that! Normally, y'all would be right, but I think these kidnappers injected ya with a serum that don't make that work. Instead, you would end up in a state of Limbo."
"An infinite space in the subconscious…" Enmu then put the gun down from his head. "Of course… My master wouldn't want me to do that."
"Exactly," James replied. "Your master wouldn't want that. In fact, I think he may be in this dream."
"Wait, really?!" Enmu was shocked. "He really came here just to see me?!" He smiled, laughing to himself in delight. "How marvelous! My master really does care about me!"
James then opened the door to let Susamaru disguised as Muzan in. "I believe y'all are Kibutsuji Muzan?"
"Indeed," she replied with a polite smile. "Thank you, Mr. Charles. Your men have protected me from harm very well here." She then turned to Enmu and took on a look of seriousness. "Bow down before me."
With a snap of her fingers, Enmu was forced down on his knees. "Yes, Muzan-sama?"
"You have served me well," Susamaru commended him. "As we speak, you have killed those pesky demon slayers in the real world, and I have Akaza taking care of the kidnappers who have put you in this dream. The boy with the hanafuda earrings is no more. Your colleague, Cleburne-san, is picking off any other resistance left with his own men."
Enmu smiled, thinking his work had paid off. "I am truly glad to hear that, Muzan-sama. It was a bit tough, but we managed to kill those fuckers eventually."
"Now that you have completed your task," Susamaru told him. "You have one final mission: Go into the subconscious of Nezuko, that one traitor demon. I believe she is running around here, as she is the last of those pests to die. Mr. Charles will see to it that she is captured alive and dragged to his room."
"My room is 529," James told him. "It's on the fifth floor."
"After this," Susamaru further explained. "You will go into her subconscious and destroy it. Upon doing so, you will return to the real world and cease all further combat activities, as there will be no more enemies for you to face on the train."
"As you wish, Muzan-sama," Enmu gleefully replied.
"Now," Susamaru concluded as she walked out. "Get to it. I'm able to leave this dream by suicide due to my resistance to the serum your kidnappers used. I'll be sure to take care of them in the real world."
Once she was gone, James helped Enmu back up on his feet and gave him some speedloaders with ammunition. "Do ya know how to use a revolver?"
"Yeah," Enmu replied. "Hairo taught me before the Flame Pillar killed him."
"Good," James nodded. "Y'all are gon' be proficient when we're done." As soon as he said that, another projection ran into the men's room, this time armed with a knife, but Enmu quickly shot him dead. "Good job!"
…
Back on the first layer of the dream, Tanjiro slashed through two projections armed with swords of their own before pulling out a revolver and shooting a third dead. He had now killed six armed projections within the dream, and as he reloaded his revolver, he said to the still and asleep bodies below him, "Come on guys, hurry it up in there."
"In here!" Two more armed projections then burst into the room, both armed with rifles. "Die, bastard!"
Tanjiro dodged a bullet in a literal sense before decapitating one of them with a sword blow to the neck and stabbing the other with a knife he pulled from his belt in the chest before stabbing him again in the stomach. Now covered in blood, he spat on the ground and said to himself, "They're not real, they're not real, they're not real…"
…
Back in the real world, Nezuko and Inosuke made it to the front of the train, where they found the conductor at the controls, armed with a knife. "Don't come any closer!"
"Sir," Nezuko asked him as she held her sword in one hand and pulled her revolver out with the other. "Please, put the knife down! I don't want to kill any humans if I don't have to!"
Suddenly, several arms of flesh sprung up from the floorboards. Inosuke yelled out, "Holy shit!" He quickly slashed at them, holding them off as Nezuko tackled the conductor, getting stabbed in the abdomen in the process and coughing up blood on him.
"Come on, fucker!" As the two struggled, Nezuko managed to punch him in the head, knocking him out but not killing him as her wound healed. "There!" Nezuko then quickly holstered her revolver and slashed at an arm of flesh as a second grabbed her leg. "Fuck!"
"Hang on," Inosuke then told her as he freed her.
"Breath of Water," Nezuko then declared as she readied herself. "Sixth Form: Whirlpool!" With several circular slashes, she managed to cut off most of the top of the engine car and deal significant damage to Enmu's body up front. As the pieces fell to the wayside she pointed to the ground and said, "His head is definitely here."
"This will be too easy!" Inosuke then jumped up into the air, declaring, "Breath of the Beast, Second Fang: Rip and Tear!" With a powerful slicing motion, he cut into the metal floor of the engine car.
"His neck bone," Nezuko thought to herself as she readied for another attack. "It's time to finish this!" She then declared, "Breath of Water, Eighth Form; Waterfall Basin!" With a downward slash, she attempted to strike Enmu's neck, but instead, she was deflected by several fleshy growths. "Fuck, he deflected me!" She then looked at the unconscious conductor and grabbed his body, telling Inosuke, "Haul his body to the back!"
"I'm the leader of this mission," Inosuke told her. "But that sounds like a good idea, so I'll take it!"
"I'm not sure who decided you were the leader," Nezuko replied in confusion. "But okay, I guess…"
"He'll be safe and sound, Kenko!"
"Nezuko!" As Inosuke left with the conductor, Enmu's flesh rebuilt the train car and arranged itself in a circular manner around his neck bone. "What the fuck… This is… His healing factor is insanely high!" Nezuko then attacked an arm of flesh that came at her. "But I have to keep going!"
