New World

Above the sky, a smiling sun shines all over the world, giving a warm feeling as if you are free from all your worries in this cold world. Diamond-shaped, crystal-clear snowflakes fell from the sky as they fell from the head of the boy and instantly melted from the warmth of his body.

"Grandpa, are we really leaving? But why all of a sudden?" Asked a child no older than 10 as he looked up at his grandpa, showing a confused expression. 

"Well, there is someone I want you to meet. He is the one who's going to take care of you from now on." The grandfather replied with a smile to his grandson, who could hardly hide his sadness.

"Ehhh?! What, why? " The kid was shocked.

"What why? You already know that I don't have much time left in this world. So I plan to give you to my friend, so he can take care of you. "

Unlike others who are afraid to tell their family that they are about to die, he is not, since his grandson is so mature that you may think he is an adult inside, so he doesn't have to worry about it.

"Yes, but what about them? Can they take care of me?" The kid asked and pointed his finger at two females, one girl the same age as him and the woman in front of him.

"*Sigh~* You know how rude it is, they have a family too, we can't just add another family to them, maybe in future." The grandfather said as he facepalmed and jokingly said the last sentence.

"Fufufu, we can take care of you, but you really have to go with your grandfather because he is the only remaining member of your family in this world, so cherish the remaining time you have," Kanae said with a gentle smile on her face, and turned her head, "Even Shinobu agrees, right?"

"Huh? Un. '" Shinobu was shocked by the sudden question. She wanted to say no, but seeing her sister's gentle smile, was too scary for her, so she just nodded.

"Ehhh?! I thought you didn't want me to leave because we planned to marry each other, but... you betrayed me! " Chisuke sadly said and started to fake cry. Of course, it's fake since he knows her real feelings. He just wants to tease her a bit and lighten the mood before leaving.

"W-What?" Shinobu was taken aback and began to furiously wave her hand, denying his words. "Of course, I don't want you to leave. I want us to marry together and have as many children as you want, but... That old pervert is dying... So I want you to enjoy your time with him even though I hate him and want to punch him in the face. He is still one of my family and I will be sad too."

"Shinobu...?" Chisuke wiped his nonexistent tears and he looked at her as if his daughter was finally getting a boyfriend.

"Pervert...? What do you mean by a pervert? Why did I not know this? Yama, what did you do?" Kanae's gentle smile started to fade, replacing it with a cold smile and a scary aura.

"Bwahaha!" Yama just laughed it off. By her mean pervert, he doesn't mean the extreme pervert where you start peeking while batting and smelling panties. Of course, he couldn't do that. He was an old man, after all. But when he heard them talking about marriage at their age, he became interested, so he began to teach them like a professional what married people do in their nighttime.

That's where the days of culture, or as he calls it, began.

And after a few words, crying, and beating, they finally leave for the destination where his friend lives.

...

...

"Grandpa, are we really there yet? I'm tired. I can't walk anymore." Chisuke asked, exhausted. They had been walking nonstop, and he began to suspect his grandfather because he had a serious expression on his face and was always on alert as if something serious was about to happen. He didn't know what it was. Maybe it was a demon, but that was impossible because the sun was still rising.

However, he ignored it because he could already see a train on which they would board.

Lastly, Chisuke sighed in relief.

"Here we are. Let's find a seat." His grandpa said

As they continued, they saw a seat near the exit, and because it was vacant, they sat on it.

"Sit here, wait for me. I will buy you some food." Yama pointed at the seat and then left.

"Something wrong? Grandpa feels different. He looks more strict and serious than he showed us before, who always smiling." He said to himself as he put his hand on his chin and did not leave his grandpa in his sight.

 ...

...

As he was finally out of his grandson's sight, Yama entered another part of the train and looked around, looking for something suspicious.

His eyes stop on a suspicious guy wearing a jacket covering his whole body, and the window beside the guy is covered with black cloth, covering the sun from him.

Like a professional actor, his demeanor changed to a sick old man and he went to the suspicious guy.

"C-Can I sit here? Because it's full..." He said to the guy, smiling and full of gentleness.

"You can." The guy just nodded, and silence fell again.

"Thank you." After a few seconds, he shows a painful expression, "Ah! My back hurts. "

But the guy ignores him as if nothing had happened. If he was a normal guy, then he may have sounded disrespectful, but he is not.

'Tsk, so annoying! I will slowly tear your limbs off and cruelly kill you because you destroyed my silence! You damn piece of meat! '

As you can guess, he is a man-eating demon. Unfortunately, the old man he is talking about is not normal.

Hey, hey! Please call... please call—"

"What?!" The guy replied with irritation.

"Ca... Call the doctor but not for me!" He immediately choked him and there was no time to react. Because of this, he fainted and then started throwing the man out the window, just to burn and turn to ashes.

After that, he leaves to find another demon to kill. 

At that time, security arrived as passengers reported that several people had suddenly disappeared and they began searching for who the suspect was.

The said the suspect was currently outside the train, throwing purple powder around the train.

Known as wisteria, these are used by corps for capturing demons and protection because they are poisonous to them, which they fear because it paralyzes regular demons and can also immobilize strong demons.

Why is he doing this? It's simple. It's to make their journey smooth and safe.

Because someone has been haunting them, and that's one of the reasons he chose to leave the Kochō household because he didn't want another family to lose.

...

...

"Master, my familiar has been killed, but I know where they are." A woman with waist-length hair of a dark brown color while holding biwa in her lap said to a man beside him.

The man snapped his fingers and then a demon appeared with droopy eyes, two horns and a lump between them.

The demon is kneeling, shaking from fear. He didn't dare speak in without great one permission.

"Bring me their heads." 

...

...

As the train finally started leaving, Chisuke put his chin in his palm as he gazed at the star.

"Just where in the world am I?" Chisuke thought

It's been 10 years since he suddenly found himself in this world. He searches for information but there's no useful news. He thinks that he's travelled back in time, but he shakes his head because it's impossible.

There are many details in this world that didn't exist in his past life. For example, people have different colored hairstyles and eyes. For example, he has red hair and red eyes, or Shinobu has black to purple hair and purple eyes.

He even thought once that he might be in an anime world, but as he didn't have any evidence, he just let it go.

"What are you thinking?"

A gentle yet strong voice rang in Chisuke's ears and felt warm in his head.

Chisuke turned his head and saw that it was a bald old man with red eyes. His grandfather is almost 100 years old, but looking at him, he looks like he could live for another year.

"Could you tell me about your friend? What kind of person was he?" Chisuke changes the subject as he doesn't have the plan to tell anyone that he is a transmigrator.

Seeing Chisuke ignore his question, he just smiled and started telling him, "His name is Tanjuro Kamado. He is a loving person but he is cunning. He also has a family. In his younger days, he was a stubborn young man that kept asking me to train him even though I'm not a demon slayer. I don't know what was in his head at that time, but eventually, I found a suitable teacher for him and as he grew old, we became friends... and..."

When his grandfather finished, he asked, "You said he had a family, but why did you reject me when I insisted I wanted to stay?"

"Well, because that's—" He had not finished his words when they heard someone shouting.

"Demon run!"

"It's a demon! Run for your life!"

"Mommy! Where are you? "

Yama immediately stood up and looked sharply at the demon standing in front of the exit.

"He seems to have finally found us. Tsk! I'm so careless!" The old man said, showing a solemn expression

Confused, Chisuke asked, "W-What do you mean, found us?"

"Yep, as you think someone haunting us."

"So the demon entered this train is not to eat people but to target us. Is that what you mean? But, but what are we?" 

"I'll tell you later because this guy is one of the upper moons, so I need to be serious a bit."

Chisuke's confused face turned pale. Of course, he is not afraid of the demon, but it's a different matter if someone is targeting you and this guy can command this demon to an upper moon, which means they are dead.

"Is this my peaceful life...?"
