Start with Demon Slayer and create the strongest demon sword!.

The Ajuuramaru in the sword also confirmed through perception that the Infinite Train had already taken the shape of a demon, and it was, if nothing unexpected happened, the Lower Moon One, Nightmare.

It seems to be in the stage of merging with the train now, but Ajuramaru can't say to what extent it has merged.

But it doesn’t matter.

Tanjiro now has his own assistant.

When its full power is unleashed, it can be killed instantly with one strike. What we really need to worry about is Akaza who appears later.

outside world.

A group of five people have arrived at the train and sat down in the fourth carriage. Rengoku Kyojuro was the first to sit in the front seat and then spoke cheerfully.

"Take a seat here, Tanjiro."

Hearing this, Tanjiro sat down beside him by the window somewhat nervously.

And Inosuke excitedly slapped the window and said excitedly, "What's inside this steel monster's body is amazing!"

"You guy, don't break the glass." Zenitsu hurried over to pull it, fearing that the glass would shatter in the next second.

Seeing that he couldn't stop it, he had no choice but to open the window.

Opposite the two of them, Fushigi Miya was sitting there looking at the two guys with a frown on his face, looking unhappy.

These two guys...

Especially the one with yellow hair, I really want to beat him to death...

On the other side, Rengoku Kyojuro crossed his arms in front of his chest, looked straight ahead and said seriously, "Come and be my stepson, I will do my best to train you!

Come to me to train, and you can rest assured!"

Hearing this, Tanjiro really couldn't hold it anymore.

"That's not good. And where are you looking at?!"

……

The train is running on the rails.

At this moment, the dusk faded and it was completely night. Looking out the window, there was endless darkness.

Several people also became cautious.

Nightfall means ghosts are about to appear.

But at this moment, the door at the rear of the carriage opened, and a thin conductor walked out, holding a ticket clip.

"Dear passengers, please show us your tickets!"

Tanjiro was still a little confused and asked, "What is this for?"

"The conductor will cut the edges of the tickets after checking them to prevent the possibility of fare evasion." Rengoku Kyojuro answered patiently.

And the conductor had already come closer.

In response, Rengoku Kyojuro handed over his ticket, which was cut into a notch by the conductor with a shear.

But there was something that no one noticed.

At the moment it was cut, the font on the ticket changed quietly.

The remaining Tanjiro and his companions also had their tickets cut one by one, and they did not notice the changes in the tickets.

But the Ajuramaru in the sword was very clear.

This ticket is the medium for Nightmare to activate his ability. The reason why he didn't remind a few people was just to kill time.

After all, there is still a long distance to reach Akaza's location.

At this time, it would be nice to let them have a good dream. Besides, I can wake them up from their sleep at any time.

"Have a sweet dream, Tanjiro."

……

From the moment the tickets were cut, everyone fell into a deep sleep.

Ajuramaru just stayed in Tanjiro's spiritual world, silently watching Tanjiro who was enjoying the family reunion.

Just quietly looking at his happy smile.

However, I also studied the structure of this dream, and I can only say that it is completely incomparable to my own. I can control the entire spiritual world.

A nightmare is like a small room in the spiritual world that can be broken with just a poke.

Nightmare's blood vampire technique also forces people to fall asleep, probably for the same reason, but it's just bad luck that this guy ran into me.

As long as I'm here, Tanjiro won't fall for it at all. He is completely immune to Nightmare's blood demon art!

……

at the same time.

Inside the first carriage.

Nightmare's palm moved independently on the ground. There were eyes and a mouth on it, and in front of it were four humans.

I saw its mouth open and a lazy sound came out.

“Soon, your sleep will become deep, and then you can use the rope I gave you to tie each other up, but be careful not to touch each other’s bodies.

Powerful ghost hunters can be easily awakened by external factors, and my dream is not infinite, as long as you find the boundaries.

Use the spikes I gave you to create boundaries and destroy the core of the external subconscious. I can't leave the front of the car for now. If you want to have a good dream, you must cheer up~"

The four people included both men and women, but all of them looked haggard, and each held a sharp cone flashing with cold light in their hands.

And they have all made up their minds.

They went to the carriage where Tanjiro and the others were and each chose one. As for Fuzugawa Miyabi, they temporarily ignored him.

The main thing is that all these scars are really scary.

In a dream.

Tanjiro turned back into his former self, took off his team uniform and the Nichirin Sword, and knelt in the room.

And the brothers and sisters who had died long ago also reappeared before his eyes, along with his mother.

It looks like a lot of fun.

But Tanjiro always subconsciously touched his waist, always feeling that something was wrong, as if he was missing something very important.

And where he didn't notice.

In the corner of the dream, there stood a young man holding a sharp spike, looking a little weak as he came to the border of the dream.

"Is this here?"

Use the sharp cone in your hand to pierce the border and walk in.

The boy stepped into Tanjiro's subconscious mind, which was the boundary between the sky and the sea. The blue sky and white clouds were reflected on the endless blue sea below.

Calm and peaceful.

When the breeze blew across the boy's face, he was completely shocked by it and couldn't help but murmur.

“Is this what’s in his heart?”

The voice just fell.

Someone suddenly spoke from behind.

“Isn’t it beautiful here?”

Ajuramaru looked at the young man who appeared here with his red eyes, and he didn't seem to be in a very good mood.

The young man didn't expect that there would be someone here. It was a beautiful girl, who made him dazed for a moment.

He answered unconsciously.

"It's breathtakingly beautiful, and...very warm..."

Hearing this, Ajuramaru could not help but nod slightly, then stepped forward and said, "That's right, but since you've come here, then please go and die!"

As he raised his hand, the dark smoke emanating from his body turned into sharp spikes and attacked.

At this moment, the young man closed his eyes in fear, and his body could not help but tremble, but the expected death did not come.

Wait until he opens his eyes.

However, he only found a hand made of halo blocking him, and the tenderness it exuded made him cry...

"Subconsciously wanting to protect others? That's certainly your style, Tanjiro!"
