A twenty-something man can be seen standing in front of a stone wall on a mountain covered in a thin layer of mist and the fresh scent of flowers and life.
On that strange stone, there are numerous names written in red and blue ink, creating the impression of a painting made up of the names of various warriors.
"Master!" A young girl who appeared to be of the cat-spirit race stood calling the young master, who appeared at ease like the wind.
"Irina-san, you are now in the same rank as that of senior master, so you do not need to call me master and all; you can just call me by my name."
Irina was the first from the earth realm to be invited to join this place and this world, which was full of things that are beyond the comprehension of human beings.
After a while, the boy and girl left the garden and entered the house. There, a number of family elders were seated, looking at the young man with a hint of embarrassment because nearly every single one of them had insisted on not including the young girl next to the boy in their ranks.
The boy sat silently, looked around with a knowing smile, and spoke lightly as he did so.
"We will be meeting now that we have discovered something interesting, and I hope you will leave your ego outside of this room." As the silence was brought down on the room, the boy's voice carried a strange atmosphere.
"Yes, it was the first time that someone on our side started to think outside the box, and we talked about multidimensionality."
The girl blushed as she nodded and turned to sit next to the boy after the boy gave her a friendly smile, and all the other older people nodded politely to apologize to her.
All of the old man smiled at this point as he watched the young master cough and try to hide his embarrassment and change in expression. The young master finally had a flushed expression on his little serious face at this point.
"Yes! As each of you has been informed, we have discovered a route to the world of dimensions, and we have discovered numerous realities that we have never seen or heard of. However, many of the species in those worlds have lethal abilities, powerful combat abilities, and fighting styles that are quite dissimilar from ours."
The boy's voice echoed throughout the space.
"Is that true? If not, they will undoubtedly one day enter our world as well, given how much the other side is growing and how much we need their strength and support."
The sense of urgency can be discerned in the voice of the old man, but he still held it back in front of his young master to make sure that he would not bring up this topic.
"Yes, that is true, and I will be going to those worlds; given that the medium spirit said that, she can only transport one living being to those worlds."
Many of the older people stood up when the young boy spoke, but they didn't do anything but watch as he grinned and relaxed because the young boy's expression told them everything.
"Master, how can we send you alone in that world?" One of the calmest purple-haired ladies finally spoke, as her words carried more weight than those of other old fogies.
Kai had to answer her this time: "I will go alone, but after a short period of time, I will have a way to restore my teleporting power, and with the bond essence, I will call one of us there."
Hearing that, she just smiled and nodded. "Alright, then we will pack things up, but carry that little lady too in that world; after all, she has the basic strength to support you in that world."
At this, Irina smiled, given that she was directly contracted with Kai. As long as he moved to that world, she was certain that she would also be called in a similar manner.
"Of course, you know that there is no way she won't be dragged with me into that world."
Kai looked at Irina with an apologetic gaze, given that it was due to that contract that there was no way that he could leave her here. After all, the intelligence indicates that even they could be in mortal danger in that world, which is full of dangerous things.
In a week, everything would be ready, and he would focus on the dojo while drawing his katana from its sheath and practicing the technique he had developed to make the most of the human body's capabilities and use it to defeat foes who were stronger than he was.
"Hmm. This quick draw is really good, Irina. Along with Ba Ji (Eight Extremities), this is a really well-suited fighting style for the mortal body."
Irina entered and set down the food that had been served a while earlier, but Kai was preoccupied with thoughts of them and none of the other members bothered to disturb him as they asked her to give it to him.
As a result, while she waited for him to finish his training, she continued to heat the food in the container using the heat prana.
Even though it had been a while since he had been training, Kai smiled as Irina brought him food, and he at last noticed that it was rather warm.
Given that it was a spirit food and that keeping it warm required special care and a significant expenditure of prana, he quickly stood up and grabbed hold of her waist as soon as he touched the food.
"You are going through Prana deficiency; are you an idiot? I can eat cold food too." He hurriedly held the girl back and regulated his prana. "Then the next time, I wish master would eat when it is heated, or else I might not be able to assist master in keeping his food warm."
"Hmm, I am sorry for being stubborn."
"This was the last time that I had been able to chat with her... After that, we traveled into this new world, and the moment I opened my eyes, I felt I had lost everything."
"Given that, she was standing right in front of me, but I was unable to touch her or wipe the tear off her face until she started to blur and vanished from my world."
"It was at this moment that I finally realized the true terror of the multiverse."
