Demon Slayer: The Demon King is actually a weak girl?!

Raindrops hit the leaves one by one, and the wind made them rustle. The rhythm became faster and faster, and the day of the sleeping people began like this.

The rain lasted for a week.

I don't know if it was a coincidence or not, but in this week, the demons in the entire Kanto area have been much more peaceful. But after the rain stopped, there were reports of multiple people missing near the busy station, and even the demon slayers stationed there had lost contact.

The Demon Slayer Corps judged, almost without a doubt, that it was most likely done by the Twelve Demon Moons.

The next day, Rengoku Kyojuro walked into the courtyard of Ubuyashiki Yoshiya with steady steps.

He made the customary farewell to Yaoya.

Before leaving this morning, he had already said goodbye to his father, Rengoku Makijuro, but his father looked very bad and seemed as if he didn't want to pay attention to him as usual.

"Are we going to go on the expedition?" asked Shinobu Kocho who happened to be there.

Kyojuro smiled and nodded: "Hmm, is it Butterfly? More than 20 people have disappeared in succession, we can't just ignore it!"

"With so many people, could it be the Twelve Ghost Moons?"

"I'm afraid so, and it's very likely an upper-rank one!"

"Really? That's really bad..." Shinobu Kocho frowned, thought for a moment, and then relaxed. "But if it's Mr. Purgatory, it doesn't seem so worrying."

Kyojuro still maintained his usual cheerful smile and was about to say something when he saw a golden-pink figure dancing towards him from a distance.

The colors are gorgeous and bright, which makes the eyes shine.

"Xiyue, you have also received a mission, are you leaving?" Shinobu Kocho asked first.

Xiyue smiled and nodded: "Yes, I am going there as a reinforcement this time. Although Mr. Rengoku may not be under much pressure alone, for the safety of the people, the lord decided to send one more pillar for the sake of caution."

As she spoke, she looked towards Kyojuro, hinting at something.

The corners of Kyojuro's lips curled up, his expression remained unchanged, and it was hard to tell what his mood was: "Hmm, then Kujo, you should also say hello to the lord, I'll go with you."

"Um……"

-----------------------------------

It was getting dark.

Several crows flew over the eaves, and one of them landed in front of the window of Tanjiro's room.

"Cack!" The crow opened its mouth and yelled, "Tanjiro Kamado, leave immediately for the Infinite Train to meet up with the Flame Pillar, Rengoku Kyojuro, and the Sakura Pillar, Kujo Shiozuki!"

“Eh——?!” Tanjiro was startled and sat up from the bed.

So sudden, late at night?!

After hurriedly putting on his clothes and taking his things, Tanjiro hurriedly ran to the corridor and found that Zenitsu Agatsuma and Inosuke Hashibira were also well armed.

After asking, I found out that all three of them were going.

Tanjiro sighed: "There are so many people..."

Inosuke glanced at Tanjiro and continued, "Wow, now that we have the training experience in the Butterfly House, I, the King of the Mountains, will show off my skills this time. Hehehe!"

"Not only are there three of us, but we've also sent two of the Pillars..." Different from the expressions of the other two, Zenitsu's face turned pale and blue, and he looked very bad. "It seems that some incredible guys will appear in this mission!"

He suddenly didn't want to go anymore!

----------------------------------------

"It seems that I was not informed of this mission."

The lazy voice sounded very listless. In the Infinite Castle, Muzan sat opposite Mingnu, observing what Mingnu saw in her field of vision.

On the face of Mingnu in front of her, there were only two black bloody holes where the eyes should be, which looked very scary.

"Lord Muzan." Naruto said while holding Biwa, "Those three boys have already set off. The eyes I planted at the station saw that they had gone there. It seems that Ubuyashiki really didn't intend to let you participate in this mission."

Wuzan raised an eyebrow: "As expected."

Although it is true that she stole many roles from Xiyue, Xiyue still carried out the work-related plots on her own.

She can't "grab" all the plots.

"That……"

"I still have to go." Muzan said, "Mingnu, send me to Nightmare now."

Mingnu bowed her head and nodded: "Yes, Master Muzan."

"clang--!"

After a dry pipa sound, Muzan arrived at the front of the train.

Nightmare, who had been waiting for a long time, knelt down in front of her and rested his forehead on her toes: "Lord Muzan, I have done everything you said."

"Nightmare," she pulled Nightmare up, "what do you think?"

Nightmare was stunned for a moment, then smiled: "Idea? I plan to merge with the entire train. In this way, the more than 200 passengers on the entire train will all be my hostages, and at the same time, they will also be my food."

"Is that so?" Wuzan held Nightmare's hand and stared at him, "Then hold on tight."

"Yes, Master Wuhan."

“……” Muzan gently let go of his hand and restrained his expression.

"madness."

She thought helplessly.

But she just closed her eyes gently and did not refute him.

……

The Demon King's shared vision is very useful. Muzan doesn't have to make any effort and can easily see what Nightmare sees.

She saw that Tanjiro and the others had already boarded the train, and easily found Kyojuro through his exclamations while eating, and sat down in one of the empty seats near him.

The person sitting next to Kyojuro was Kujo Shiozuki.

Several people looked a little unnatural.

Muzan suddenly remembered that he had not had much interaction with Rengoku Kyojuro in this round. If she hadn't done anything naughty, wouldn't Xiyue have "taken advantage of the situation" and had an affair with her eldest brother?

But the train carriage is a public place, and they can't do anything openly in public. Now even if they can see through the sky, they can't see anything.

Besides, the answer is no longer important to her.

After figuring it out, she asked Naruto to teleport a few ghosts that looked scary, according to the plot in the book, to give them some experience, so that Tanjiro and the others could see the majestic figure of their eldest brother slaying ghosts, so as to establish his image as a wise and brave man.

Kyojuro chopped the two huge demons into pieces according to the original plot.

The three boys smiled and shouted "Brother Purgatory", vying to be his stepson.

Kyojuro stood in the middle with a hearty smile, and the three boys circled around him happily.

This scene and situation creates a sense of joy before sadness, which serves as an emotional contrast to the subsequent plot in which someone is stabbed to death.

Everything is going according to Muzan's idea.

Not long after they touched the ticket mixed with Nightmare's blood, everyone fell into a deep sleep.

And Xiyue was resting her head on Kyojuro's shoulder.

"It's exactly the same as what's written in the novel, as long as I'm not around."

Wuzan held his chin with his hand, feeling his brain was tired.

According to the novel, everyone had their own dreams afterwards, and everyone except Zenitsu ended their dreams on their own.

This is where the fun begins.

So during this period of time...she can only wait?

Wuzan kind of regretted not bringing this book to read.

Suddenly, a mouth appeared on the piece of meat that Nightmare had fused with in Muzan's carriage.

The upper and lower lips of the mouth opened, and began to speak through gritted teeth: "Damn it, that guy... that man wearing Hanafuda earrings must die!"
