This is utterly bewildering.
Not only did we enter a movie that didn't appear in the original work, but that movie is Demon Slayer: Mugen Train?
Moreover, I clearly heard it before we entered—it was a special screening.
What on earth is going on?
'Let's think about that later. For now... clearing this movie is what's important.'
Coming to my senses, I looked at the party members who were panicking because they didn't know what movie this was and spoke.
"Everyone, have you ever heard of a manga called Demon Slayer?"
[Constellations within the channel are bewildered by the sudden filtering.]
'Huh? Filtering?'
I was momentarily taken aback by the Constellations' mention of filtering, but there was no time now, so I decided to think about it later. I looked at the party members' expressions, but they all seemed clueless.
"Sigh.... Since you all seem not to know, I'll explain briefly. It's a manga where the protagonist and his comrades defeat bad guys called demons... I'll skip the other details and just briefly explain this movie."
Then I pointed at Tanjiro's group and said.
"The black-haired one over there is the protagonist, and the three around him are his comrades. The story is that when people start disappearing on this train, they suspect it's the work of a demon and come to investigate, then encounter and fight the demon... that's the gist."
Jung Heewon, who was listening to my explanation, suddenly asked as if curious.
"Then where is that demon?"
"Probably... according to my memory, it should be on top of this train."
"Then instead of wasting more time, let's just go catch that demon right n—"
"If we do that, we'll be wiped out."
I replied coldly to Jung Heewon's words.
"The stronger demons have unique abilities called Blood Demon Arts. The one up there has one too."
"What ability does the demon up there have that makes you so worried?"
"The demon up there is named Enmu. His Blood Demon Art is called 'Forced Sleep,' an ability that forcibly puts a target into a sleep state and makes the sleeping person dream whatever Enmu desires. Once you're caught, it's not easy to break free."
After saying that to the party, I glanced at Tanjiro's group and spoke.
"First, let's secure their cooperation."
Since I had just explained that they were the protagonist and his party of this movie, the party members all seemed to agree.
Screech.
"Tickets... I will... check them."
Right on cue, the door on the opposite side opened and a conductor who looked somewhat off entered the compartment. Having heard the story from Kyojuro, Tanjiro handed over his ticket without any suspicion...
"Wait, stop right there..."
I urgently grabbed the conductor's arm, preventing him from checking the ticket.
"What... are you... doing..."
"You must be sad because you lost your precious family... So you want to see that family even if it's in a dream... But even so..."
CRACK!!!
"To help a demon for a brief moment of happy dream... That's not right, is it?"
"""What!?"""
"A demon!?"
Seeing Tanjiro's group flustered by my words, I immediately knocked out the conductor and said to Tanjiro.
"Demon blood is mixed into the train ticket. Smell it."
Tanjiro immediately smelled the train ticket he was holding and soon shouted in surprise.
"! It's faint, but it definitely smells like a demon!"
"The demon here has the ability to forcibly put people to sleep. If you had punched that ticket normally, all of you would have fallen prey to the demon's ability and gone to dreamland."
Hearing my words, Tanjiro's group was astonished and then thanked me for helping.
'How should I put it... Hearing a thank you from a manga character I liked feels a bit strange... Or maybe I'm already used to it?'
"Now! First, listen to me! According to what I've figured out, the demon is currently in the lead car of this train. I don't know what it's preparing there, but if we leave it be, something big will happen."
"Certainly..."
"So I'd like you to cooperate with us."
I waited for Tanjiro's group's answer.
After a brief silence, the first to answer was Rengoku Kyojuro.
"If that's the case, as a member of the Demon Slayer Corps, I will naturally cooperate!"
Next, Inosuke answered.
"I don't get what's going on, but fine!"
Following Inosuke's words, Tanjiro also spoke.
"To defeat the demon, I will cooperate too."
In response to Tanjiro, Inosuke, and Rengoku's answers, I looked at Zenitsu.
"Impossible! Impossible!!!! Absolutely impossible!!!"
Seeing Zenitsu shaking his head violently, I gave the party an OK sign, and the party members also nodded.
"First, just in case, let's split the party... You, come with me to catch the demon... And the rest, please protect the people from any potential demon attacks."
At my words, everyone nodded. Soon, I moved to climb onto the train roof together with Tanjiro.
Clack clack!!
As I opened the compartment door to climb onto the roof, Tanjiro smelled something, covered his nose in surprise for a moment, and then we went up.
Whoooooosh
Once on the train roof, a strong wind blew from the front, and within that wind, a demon stood nonchalantly.
"This... seems to have gone off plan?"
Seeing the creature speaking so calmly, the two of us prepared for battle.
"I was trying to show you a nice dream... What a pity..."
I found its words ridiculous and spoke.
"Don't make me laugh... you damn bastard. You who enjoys turning people's happy dreams into nightmares and watching them suffer..."
[Constellations of the Absolute Good alignment are horrified by the character Enmu's cruel actions.]
[Constellations of the Absolute Good alignment are disgusted by the character Enmu's actions.]
[Constellations of the Absolute Good alignment are enraged at the character Enmu.]
Then, Enmu, looking at Tanjiro, made an expression as if realizing something and spoke.
"Oh? You have earrings."
Soon, Enmu, smiling, raised his hand high and said.
"How lucky? You've already come to my side!! It's like a dream! With this, I can receive even more of Lord Muzan's bl—"
Bang!
"Huh..?"
Something that flew in an instant pierced through the creature's crown.
Not understanding what had just happened, Enmu made a bewildered expression and then looked at me.
"You're damn noisy... Come at me, you crazy son of a bitch..."
I gave the bastard the finger and loaded the E.G.O Magic Bullet, while Tanjiro beside me also drew his Nichirin Blade.
"E.G.O Magic Bullet, First Round — Magic Bullet!"
"Breath of Water, Tenth Form: Constant Flux!"
Seeing us, Enmu used his Blood Demon Art.
"Blood Demon Art: Forced Sleep — Whisper of Hypnosis"
[Character Enmu activates Blood Demon Art: Forced Sleep — Whisper of Hypnosis.]
"Sleep tiiiiight!"
Just like that, we were almost caught by Enmu's Blood Demon Art, but...
[Activating skill Dispel Lv. 1.]
"By the light of purification!"
Then, something rose behind me, and as something spread its wings, the creature's Blood Demon Art was nullified.
Bang!
As his Blood Demon Art was easily nullified, I fired a Magic Bullet at the flustered creature, blowing off one of its hands, and immediately said to Tanjiro.
"Let's keep attacking like this!"
"Yes!"
We continued to launch attacks at Enmu.
