When Yuta and the others took their seats, a woman who seemed to be their homeroom teacher came in at the same time as the schedule.
　Everyone naturally paid attention to their homeroom teacher for the first time in their high school lives.
　But this one can't help but attract attention.
　A slender figure. Slitty and perfectly dressed in a white suit. A high nose, with a prominent nose. Eyes that carry intelligence behind silver-rimmed glasses.
　The classroom is abuzz. The boys are all red in the face, and a sigh escapes from the girls. The woman stands in front of the podium, removes the seating chart from the blackboard, and quietly begins to write her name in chalk.
　There was no sense of futility in this series of movements.

''Congratulations on your enrollment, everyone. I'm Takano Mirei, the homeroom teacher for Class D. I've been with you all year. I'm looking forward to working with you all throughout the year to make the class more exciting. I look forward to working with you all this year.

　A bland, common greeting.
　But it was powerful enough to erase the buzzing and fluttering of the students in Class D. The new homeroom teacher's expression didn't twitch. The new homeroom teacher's expression didn't twitch. The students are also frozen.

''Everyone. Any reply?''

"...nice to meet you!

　A breathtaking response that was hard to believe was a new class that had just been created.
　In just a few seconds, the homeroom teacher, who introduced herself as Birei, made everyone understand firsthand the level of leadership she possessed.

''Good. Now let me explain the schedule for the future.''

　The new homeroom teacher, who is truly a cool beauty on the ground, begins to explain in a nonchalant and easy to understand manner. It seems that his appearance gave the students a sense of tension and deep loyalty, and all of them are silently taking notes with eyes that say they will follow you.
　

(This guy!　(Swallowing everyone's ki........and having your own ki covered in class?

　Yuto stares at his homeroom teacher's back as he faces the blackboard.
　That's what happens in kobudo. Maybe he's mastering some kind of martial art, Yuto thinks to himself.
　But then Masato felt his homeroom teacher's ki rise even higher. He can feel that ki of his homeroom teacher rising to a fierce level on his seamless back.
　Yuto looks at it as if he is absorbed by it.

(That's........Little Zhoutian!　It's just, wow. I don't even feel evil. He's doing it on purpose!　Why?　You're showing me this?　(No, you don't know about this one.)

　Miura turned back to me and met my eyes with Masato for a moment. He moved his mouth in some way and grinned for the first time.

''Eeeeeeeeee!

　When Yuto suddenly and vigorously stood up, the students around him stuttered and, in unison, focused their gaze on Yuto.
　Yuto froze, sweating at the bad atmosphere he had created, "Ah........
　Both Ichigo and Shizuka's eyes widened, "What the hell is going on?　The look on his face is.

'You ... what is it?　Uh, you must be Du Du.

　Birei says after checking the list of names. It's more like a jammed question than a question.

''No ... sorry. Nah, it's nothing.''

Then sit down.

Yes.

　Yuto sat down with a shrug. However, Yuto did indeed read the words that his homeroom teacher had said with his lip-reading technique.
　It was "Give my regards to Master Sumazo and Master Sun..."....
　The homeroom teacher, who confirmed the confused Yuto sat down with a blank expression, turned his face to the front.

''Well then, everyone. We will begin homeroom. As I said before, your seats will remain unchanged until the next midterm exam. You can ask questions at any time. Please ask as you go. Now, I will ask everyone to introduce themselves today, check their lockers and clogs, hand out any handouts or other materials that you need to fill out, and then we will dismiss the class. We'll take some time in our next homeroom, and we'll decide at that time what your roles are in class.

　Under the command of the new homeroom teacher, one by one, the students introduced themselves and the first day of school was over.

Yes, thank you for your hard work. That's it for today. Tomorrow is a holiday for everyone except the dormitory students, so I'll see you the day after tomorrow.

　As the students begin to prepare to leave the school, Birei turns to Yuto.

''Also, DoDu-kun who made a fuss earlier. I'm sorry, but could you please collect the printouts?　Also, I need a little help with something, so please come with me to the staff room.

Oh, yes..... I understand.

　Yuto was slightly puzzled and felt that the boys in his class were jealous of him, but he followed Miura. Nevertheless, he naturally thought that the students around him had been spotted by the blunder he had just made.
　Yuto nervously followed after Miura and entered the staff room, placing the printouts he had collected in class on Miura's desk.

'Thanks for your help,'

Oh, that teacher. I need help...

That was a lie. I have to tell you something. To you.

...What is it?

''There's no need to be so nervous. Yes, I wonder if you didn't think it was strange when you entered this property, Dou Dou Dou?

　Miura sat down in her desk chair and crossed her legs, catching Yuto in front of her and resting her elbows on the desk.

'For example, yada yada yada yada...'

　Miura re-crossed her legs and looked at Yuto's face as if she were observing him, and he looked away lightly.

''That's true. Because that's the kind of place I chose to build this school in.''

'What!　Um, I don't know what you're talking about...

'You're surprisingly cautious. Then can I tell you that I'm just like you ... just like I showed you the Sacred Ki earlier?

..........

'I've heard about you from Master Chama Zang and Master Sun. Don't worry. This is an ordinary school. However, I will tell you that you and I, and a few others, have those students and teachers. Otherwise, I don't want you to be surprised later.

'Huh...'

'That's what I mean, but other than that, it's a very normal school, so we're not aware of each other. Besides, in your case, it would be better to have someone who understands, wouldn't it?　That peculiar constitution and all that.

'You know about this!　My this!

'Yes. Well, even if they don't tell you, you'll probably think it's weird as soon as you meet a race like us. So I've told the current students and teachers of our kind ahead of time about the peculiar nature of that massive amount of spiritual power just leaking out in vain. It's better than complicating things then, right?　And don't worry, I didn't tell you anything else.

　After hearing that explanation, Yuto becomes serious.

''Can I ask you one thing?''

Come in.

How much the same is the same as me?　And how much do you know?　About the Dou Dou family and so on........ If you don't mind, I hope it's okay with you.

I'm asking two questions. Fair enough. Yes, I'm a Taoist, too. I'm a student of the same path as you. I've also received some liberations from Master Sun. And I wonder if I'm your senior in that regard?　Although, unlike you, I am one who has pursued the Sendo from the beginning. As a matter of fact ... you and I have met before, haven't we?

'Yes!　Really?　I'm sorry, I don't remember that at all...

''Don't worry about it. The Dou Dou family is really rare, and they are a family that is closely related to the Immortal World.... We don't even have any interaction with other people of ability, if at all.

　Mei-Li exhaled lightly and her expression softened, though slightly.

''Also, another question, I know a lot about the Dou Dou Dou family. As far as I know, they are the family of the most powerful spirit swordsman, and the property they manage, and that you passed through the Demon Lai Grotto and stayed in the Demon World beyond for about three years.

'Hey! That much......... I even know the time difference with the demon world........

　Yuto listens with a serious look on his face.

''Don't worry. Only a few people in the Sacred World know about this. That's because this is an insurance policy. It's a dangerous property that could shake up that many worlds, right?　It's good as long as the Dou Du family has the power, but if not, we have to do something about that thing. Even the Three Immortals who are watching the operation of the universe are concerned about that thing.

Really........I had no idea. Eh, no way!　Was it an insurance policy for Master Sun to come to me, who couldn't become a spiritual sword master because of this constitution?

I suppose that's the way it goes.

You never tell me anything like that, Grandpa.

'But as I've said many times before, other than that, this is a very normal school. Just be normal. You and I are both teachers and students. Even if it's only a couple of weeks here, I know it's hard for you because you're a blank who spent three years in the Demon World, but we don't give you any special treatment either, of course.

'Oh, yes. Please do so.

Okay, that's enough talk. Have a safe trip home.

Yes, I understand. Well, I look forward to working with you in the future.

　Yuto bows and leaves. Birei watches Yuto leave the staff room.
　However, unlike earlier, there is something in his eyes that does not resemble this teacher.
　It may be something that can be taken as passion or adoration.

''........Yes, it's nice to meet you. I will never forget you. I will never forget you, no matter what happens....

　It was a whisper, but it was a sure and powerful tone of voice.



　Yuto, alone, went to the elevation and put his tops in his newly assigned clogs and changed into his shoes. From Ichigo, he said, "Shall we wait? I felt bad and asked him to leave first.

'Huh. But I'm surprised.

　As Yuto walked, he didn't expect that someone like that would be his homeroom teacher at the high school he had finally entered.

(I had heard that the principal was an acquaintance of his grandfather's, but I wonder if the principal is also some kind of "gifted person"?

　It reminds me of the principal's wobbly figure and his speech at the entrance ceremony.

(What's that..... Are there any decent people my grandfather knew?)

　Sighing heavily, Yuto thought about the future. No matter which angle he thought about, he was worried about his own future, which was difficult to look forward to. But for now, he had to face the immediate issues.
　First and foremost, he needs to secure a source of income after the move.
　That's when Yuto realized something important.

''Ah, I'm going on a patrol of the enclosed area at the end of next month!　Well, I guess I'm stable now.......but I'm busy. Totally, I was born into an awkward family. And thanks to my constitution, I'm a dropout...



　There is another side to Du Du Yuto that he has not told anyone about.

　The Dou Dou Dou family has inherited the ability to fight monsters and demons, which has been passed down from generation to generation.
　Because of such a family environment, Yuto has been trained to inherit these abilities since before he can remember.

　However, unlike other families of gifted people, he does not actively receive requests to evacuate demons and spirits.
　For a long time, the Dou Dou family has kept such jobs to a minimum to earn a living.
　In fact, we don't have to do this kind of work anymore.
　In fact, the reason for this is because the Du family does not do anything that would make them stand out in the world.
　The only reason why the Du family does not stand out in the world is because the Du family does not have to do anything more than it has to. However, the truth is that the number of students is not so small and the number of students is so small that it's not really a small matter....

　This is because of the special circumstances that the Du Du family has that are different from other families of people with abilities.
　The Du Du family had to fulfill an important role that the Du Du family themselves had imposed on their family.
　It's a secret, but the Du Du family is in charge of a dangerous property that could spell disaster for the world. When and why the Du Du family was killed in this role, Yuyin is not told.

　However, there are several seals and wards under the management of the Du Du family that cannot be called dangerous.
　And as if to match it, the abilities handed down to the Dou Dou family had been passed down to them, powerful techniques that were good at building boundaries and sealing the vague ground of dimensional walls.
　From generation to generation, the Dou Dou family has played such a role, and from the past to the present, they have regularly patrolled for particularly important seals, making it their duty to repair, reseal and re-enforce the wards.

　And........among those properties.......there is a certain cave that the Doudou family pays special attention to.
　The history of its existence is not known, but Yuto was told that it was also the birthplace of the Dou Dou Dou family.
　That cave, deep in the Chichibu Mountains, is called the Demon's Grotto or Demon's Window Cave, and it is one of the most dangerous caves in the super dangerous properties managed by the Dou Dou Dou family.

　What makes it so dangerous?

　That was because ... the Demon Laird's Grotto was always open in this world, a great hole of dimensions.
　Always open........the great hole of this world. The Demon's Grotto is a secret art passed down in the Dou Dou Dou family, and a powerful boundary has been put in place to prevent people from coming and going to the other side.

　The other side is.....

　The other side is another world and the home of many outsiders.
　The other side is called the [Demon World], an otherworldly space that is next to this world.

　The cave that led to this [Demon World], a ridiculous property, was too dangerous to be left out in the open, no matter what era it was in.
　That's why the Du family has made it their most important job to patrol, repair, and re-strengthen this cave's boundaries, among the many seals and boundaries.

　They are not asked by anyone, nor are they admired by anyone. However, the Dou Dou family has fulfilled this role as a duty, and according to the story, they have been martyred in this role for nearly a thousand years.
　For that matter, not a few people are proud of their own house, not a few of them are also proud of their own house.

　In the first place, it is common knowledge among those with abilities that loose or distorted dimensional walls are actually not so rare cases.
　However, it is often due to sudden coincidences, certain special cycles, or special interference in certain spirit lands that cause the walls of this world to relax. It is generally said that this is so difficult to detect in advance that it is impossible to know for sure.

　There are exceptions to this rule, such as the so-called secret methods, which are the use of witchcraft and legal arts to interfere with the Dou Dou family's property.
　A secret method is a completely different theory, view, and power than modern science.
　The abilities themselves are alien to ordinary people, but nowadays, the common sense of modern science has crept into those abilities and they are unrecognizable.
　It is impossible for humans to materialize what they cannot recognize.

　However, what was unusual about this demon cave was that it was always open without any kind of secret technique or cycle.
　This kind of thing should not exist, it should not exist. A substitute that I don't even think there is such a thing.

　And ... what would happen if it were known that such a thing existed?

　If this great hole was exposed to one of them, there might be some people who would think of something bad or even an outsider.
　In order to protect this great hole from those unforeseen events, one could imagine that the people of the Dou Dou family needed a powerful force in addition to the sealing technique.

　The direct lineage of the Dou Du family was a family of spirit sword masters for generations.
　Although there are some families of Chinese gifted people who are also family members of spirit swordsmiths, the one of the Dou Du family is a bit different from that.
　A spirit sword master's sword is a sword as it is meant to be, and at the same time, it has characteristics similar to a legal tool. Therefore, it is more meaningful as a ritual vessel for the release of a legal system.
　However, with the Dou Dou Dou family's spirit sword master, it is more of a fuller sword technique and specialized for close combat. In other words, he is a spiritual swordsman of the Du Du style.

　The Dou Dou family has been able to deal with all kinds of situations in the past by combining powerful sealing techniques and powerful close combat abilities.
　On top of that, the Du Du family has used their wits and sometimes their power to prevent the world from knowing about these dangerous properties, and as a result, they have been protecting the family for over a thousand years.

　But then a problem arose.

　Unfortunately, the direct descendant of the Du Du family, Yuto, did not have any talent as a spiritual swordsman.
　This was the first time in the history of the Du Du family that such a thing had happened.
　However, Grandfather Couzou didn't seem to be bothered by this unusual and emergency situation. "Well, it's okay if you have other abilities, right? He said smoothly, and the person he brought with him was Sun Wei, a master of the Sacred Way. He looked like just a drunken old man, and he was a close friend of Sumazo.

　Why didn't Yuto have any talent as a spirit sword master in the first place?　
　The reason for this was due to the fact that Yuto had a very troubling constitution to become a Spiritual Sword Master.
　No, it was a troubling constitution even when considered as an able-bodied person.

　This is because the large amount of spiritual power that Yuto himself possesses is constantly being emitted, regardless of whether he is conscious or unconscious.
　Normally, psychic power is emitted when an ability is activated. In other words, it is the catalyst for the activation of their abilities.
　However, the psychic energy comes out of Yuto's body on its own.

　So why don't you use the psychic power that comes out on its own?　However, it is not so easy.
　The abilities that an ability holder can manifest vary enormously, depending on the size and density of their spiritual power and the attributes that are added. The psychic power is manipulated by the psychic by their own will to activate their own abilities.
　Furthermore, the size and density of the psychic power and its added attributes are, in a sense, like a recipe for cooking.
　In other words, it is similar to completing a dish by using seasonings such as attributes around the ingredients called spiritual power. The same thing can be said for those with magical abilities.

　This is why the fact that a large amount of spiritual power that Yuto can't even cook is coming out on its own was a fatal problem for an ability holder.
　Also, as an addendum, the activation ability of each gifted person will vary depending on their personality and the skills they are good at.
　The recipe for this ability holder is a matter that no ability holder wants to know too much about. Knowing it doesn't mean you can use it, but the fact that the origins of the ability and its roots are known can lead to the development of an anti-technique.
　In other words, it could be said that this was a matter of life and death for those with the ability.

　At any rate, Yujin's spiritual power itself was always coming out, and besides, he had tried many times to control it, but it didn't work. The only saving grace is that he has only mastered the sealing technique, which can be considered a lifeline for the Dou Dou Dou family.
　However, this was the main reason why he lacked the qualities of a Dou Dou Dou School Spiritual Sword Master who could control the spiritual power of the Yujin at will.
　In addition, there is a high probability of being attacked by miscellaneous spirits when they approach a spiritual place. As expected, Yuto felt that this was quite annoying.
　His parents were troubled by his peculiar constitution and invited Sun Wei through the connections of Kazo to help him learn the path of enlightenment, a power that does not involve spiritual power.

　In fact, there is a reason for the decision to have him learn the Immortal Way.
　The reason was that Xianqi in the Xian Dao was not limited to spiritual power and did not repel the power of other lineages.
　This was the reason why Yuuto was allowed to study Xiandu, that there was no problem with having spiritual power and Xianqi living together in one individual.

　This idea is premised on the common sense of the gifted world.
　First of all, most people with abilities have either spiritual or magical power in their bodies to exert their power, and that is almost 100% inborn.

　And above all, spiritual and magical power are violently opposed to each other because the roots of their powers are different. For this reason, there is no such thing as a sorcerer who has the ability to use spiritual power. In other words, it is a common theory that it is virtually impossible for an individual to have both spiritual and magical powers.

　The other was that the sacred path was not inborn. The Immortal Dao was something that was acquired by cultivating one's life force to the extreme.
　In other words, it was possible to learn it from scratch. Furthermore, the sacred ki acquired through the cultivation of the Immortal Way does not conflict with spiritual or magical power.

　For these two reasons, the Dou Dou Dou family tried to teach Yuejin the Sacred Way.
　When you hear it like this, it sounds easy because neither of these two things repel, but it is not an easy thing to learn the Xianqi.
　The proof of this is that most people involved in Xianqi, or those who are said to be hermits or daoists (though some are not human), have devoted their lives to mastering it. Countless others have lost their lives along the way.
　However, since the pursuit of the Immortal Way is closely related to the quest for immortality, a lifetime could be hundreds of years....

　Although Yuuto had been cultivating for more than ten years, considering his current abilities, it would not be an exaggeration to say that he had qualities that were beyond the norm.
　He himself was not aware of it, and the people around him did not tell him about it either...

　As for his teacher, Master Sun, recently, as soon as he gives a few instructions, he says, "The rest is up to you to train on your own," and he is always busy drinking sake with the storehouse.
　This is partly because of this background, but to Yujin, both of them look like just a bad old man. In addition to that, the same kind of people call friends, or perhaps there are many unusual people around the Kazura. That's also a source of concern for Masato.

　The faces of the most recent two people came into his mind and he quickly erased them as he felt uncomfortable.
