Thus, I began to train for 'Trading with the World' with Sis-san.
　By the way, Diprakra-san moved into the castle to make the clothes as an example, and the boy, Legacy, went out of the castle in a daze.

　Right now, there are three of us in the garden, me, Sis-san and Yotaki.
　I close my eyes as if I were meditating and start practicing the method Sis-san taught me, repeatedly.

　Without resting, over and over again, I convert the 'demonic poison' inside and outside my body into another power. However, no matter how many times he repeated it, all he could do was feel his vision expanding as he had just done, and there was no progress.

　According to the story, this 'demon poison' is the 'source' of all matter.
　If you want to, you can convert it into cold air like a waterfall. In other words, I'm still inexperienced and can only convert it into what I'm best at--

　''Yes.
　This should be able to replace the 'Demonic Poison' with the 'Yangtaki's Sickness Pill' as long as I have the sense to do so.
　I'm sure the apostles are hoping I'll be able to reach that realm as well.

　--Repeated trial and error.

'............!'

　I'm not out of breath.
　But I can't stop sweating.
　My body feels strange, and my temperature keeps rising. Not only is my concentration polished off, but I can see that my strength is being taken away from me in a very real way.

　It doesn't hurt, but it's painful.
　However, my sister, who is probably even more painful than me, is waiting for the treatment method to be perfected. As long as Yotaki is watching over me by my side, there will never be a giveaway from me.

　I meditate and repeat my 'deal with the world'.
　As per Sis's advice, I prioritize images over theory, feeling the flow of the world with my skin, being aware of my own 'circulatory function', concentrating on the power that flows in from the 'other side', and then--!

"--Okay!　Round and round (・・・・・) ......!!!

　After an hour of meditation, I finally swear at the end of the day.

　The first thing I stumbled upon was the phrase 'dealing with the world (・・・・・・)' - (...).
　It wasn't the difficulty of the task, but rather the frustration of the images conveyed by the phrase.

　The apostles probably thought they were teaching with honest and careful language.
　We are dealing with the world, so 'dealing with the world'.
　It's so simple, so right - but so hard to describe.

'This makes it hard to imagine: ......!　More, more ......!

　As Sis taught me, there is no doubt that image is the most important thing.
　In fact, after I heard the soft expression 'something magical' from her, my 'deal with the world' was a success.

　That means that the term "dealing with the world" is not appropriate for training, isn't it?

　It's as hard as a word in a textbook. And long.
　No, I don't hate long. I like shouting out long names. For example, I like the long names of special moves that look like all the moves in manga and video games that are often the final move in a game. However, in this kind of low-key, repetitive practice, long names can only be a detriment. What's important in the imagination is a direct link to the imagination--a connection.

　-- a vice that causes me to decide to tweak the word 'otherworldly'.

'More straightforwardly ....... 'Trading with the world' would be better called 'magic' now ...... no, still .......

　I can't call it 'magic' yet.
　Intuitively, I felt that way.

　From the advice Sis-san gave me about 'something magical', the word 'magic' is most likely to have a unique meaning in this world. Also, simply, those two words are the two most exciting words for me, and the easiest to imagine for "Gentiles". I wanted to keep it as a celebration of the completion stage, not the development stage.

　So I choose it as my runner-up.
　The most appropriate word at this point in time.

It's 'sorcery'.
　'Deal with the World' should be 'sorcery'.

　I've been thinking about it since the word 'quid pro quo' was first mentioned.
　For 'dealing with the world', which always requires losing something, the word 'witchcraft', which has a slightly darker impression, would be appropriate. It's a personal feeling, but the image of a sorcerer dealing with black power comes to me intuitively.

You don't even need the word 'circulatory function' anymore: ....... You don't have to be aware of this because it's a bodily function. The body is going by itself.
　-- So, this is a 'predisposition (...)' for now.
　Let's just call it the 'qualities' that break down the 'evil poison'.

　I'll continue to simplify the words.

　In other words, I have the 'predisposition' to circulate the 'Demon Poison'. That's what I got when I was summoned. However, the tendency of that circulation is specialized for each and every one of us. My strongest 'spellcraft' was 'dimensional power'.

　Ah.
　This is already completely--.

''--then the tendency that individuals have is an 'attribute (...)'
　I'm a dimensional attribute and Yotaki is an icy attribute. Ah, that's right. This is nothing but an 'attribute'. ......!

　It's getting to be for me in a good way.
　In other words, I've been called to the 'other world' to understand the 'qualities' of my own dimensional attributes and become a 'vessel that can adapt to the demonic poison' - and

''Let's also abbreviate this 'vessel that can adapt to the demonic poison'. This is, frankly, 'vessel'. No, 'fittest' would be cooler: ......?

　The tone increases.
　Gradually, the heat in my body, which was only painful, becomes comfortable.

　However, Yotaki and Sis-san, who are watching over me, are terribly confused. The content of their conversation reaches me in passing.

''Ni, brother ....... That's all a game term .......
Hmm?　Kanami started to mumble something. Weird Japanese.
'Perhaps your brother is complaining about the name he was taught by the Sith and others. Right now, he's trying to make 'Vessel that can adapt to the demonic poison' into 'The Fittest' ....... Huh.
'Complaining ......?　What, are you complaining about the name?　Does that mean it's a long hassle?
'No, it seems to be a long one. He just doesn't like it: ......
"...... Hmm. "The fittest", huh? I mean, you want me to call you 'The Fittest'? Like our 'Sith Apostle'.

　When Mr. Sis mentions my name, an electric current runs through my brain.

　...... and "Kanami the Fittest"!

　I realize that the 'vessel that can adapt to the demon's poison' part is involved in my name calling. I immediately throw away the original purpose of shortening and start thinking about the name I want Sith-san to call me.

　The unconventional 'fittest' is not a bad idea. But if I wanted to, I'd prefer it to be longer. I have a personal theory that the longer the term is, the better it feels when you say it. The longer the better, the more comfortable it is to say these coined words. I will ponder what is appropriate for this world and its circumstances.

　And then I came to one word.
　Very naturally, the word came out.

'--Okay. Let's make 'the vessel that can adapt to the demon's poison' 'the one that steals the reason (・・・・・・)'.
　In other words, I'm 'Kanami, the one who steals the reason of the dimension'. This way, when I use the 'power of dimension', it's easy to imagine a series of steps: ......!

　So I stopped meditating and glanced at Yotaki and Sis-san, who were chatting in the distance.
　My sister seems accustomed to my wishes and tells Sis-san with a sigh.

'...... haha. Err, Sis. It seems that my brother wants me to call him 'Kanami, the one who steals the reason of the dimension' instead of 'Kanami, the fittest'. ...... Sorry, I'm such an older brother. But he's not a bad brother.
"Steal, person ......?

　Hearing that, Sith-san showed a surprised expression.
　I may have gotten carried away and used a strange name too much. When I was about to reflect on that

'--you know what (・・・・・・・・). I think it's a good name. I'll call it that next time, too, instead of 'Vessel that can adapt to demonic poison'.
What?

　The praise comes back, which surprises Yotaki. I'm surprised too.

''......?!''

　It's been a long time since I've had someone understand my sense of style.
　I've been told that in my former world, I tend to dream, but in this 'other world', it might be a sense that is normally accepted.

　A strange feeling of happiness bubbles up in my chest, and I close my eyes again, embracing the heat.

　Strangely, I felt that all the fatigue from today was gone.
　I could feel the flow of this world's "demonic poison" flowing more clearly, and I felt like it was blessing me. Fortunately or unfortunately, my siblings and I were summoned to the "Other World". But this 'other world' is right for us. If it's not good, it fits (・・・・・・・) this Aikawa Uzumi (・・・・・) better than the "Original World (・・・・)" (...).

　I thought.
　I don't know if that was a coincidence or a necessity.
　But under that conviction, my "dealings with the world" - no, my "spellcasting" is sharpening.

　The power of the dimension overflows from my body.
　Obviously, the amount is greater than before.
　An expanding sensation reaches the edge of the garden.
　It's as if the third perspective is not overhead, but soaring into the sky.

　Sis seems to be feeling the evolution of that 'spellcraft', and she is following the filling magic power with her eyes. And he talks with Yotaki about the results.

''Nah......!　In a short time, so much for ......!　Great!　It sounds like the act of changing the name now is one 'price to pay': ......!
'Oh, so that's the 'price' now?　With that?
Yes, that's fine. The act of thinking of a new name, carving it and writing it down is a noble 'compensation'. As I said before, everything in this world has to be paid for. Anyway, as long as you have the 'price' of action, you can intervene in the transactions of the world.
............. Are you sure it's that easy?
''Well, there are probably only five people in the world who can do it this easily, including you two and the other ...... er, three of the 'reason-stealing ones'. For the rest of us, the ...... 'qualities' in the first place?　I don't have one of those.

　Sis-san uses the words I've decided to use with vigor in a disciplined manner, and then explains them to Yotaki in a simple way.

　Then, at the end, he blurts out. It was a small voice that didn't even reach Yotaki in front of me, but I could hear it as my senses expanded.

'The name is 'The Price'. ...... It's a little nostalgic. The Kazeiko also started out by using her name as a 'compensation' to generate stronger winds .......

　It seems to be a means with a precedent.
　At the same time, it turns out that names are an important thing in this world. This is also common in the magical world of RPGs. Again, it's easy to imagine and it really helps.

　I can't believe that every name and word has power and interferes with the world .......
　It's really for me: .......

　I say it when the world's favoritism for me turns into a certainty instead of a guess.
　I don't have time to think about it, but I cherish each one naturally and with a certain meaning--

-- "'Lost to Aeka', 'Past time, nostalgic home, sorrowful home', 'All for the blessing of new beginnings' --

　The resistance that existed in the original world was almost non-existent here.

　This is a 'different world'.
　The only person beside me was Sis-san, who said "I understand" and "it's fine", and my family, Yotaki.

　On top of that, I was more excited than ever.
　Today was all new to me, and every single one of them was like my favorite game. Yotaki started to head out with a bang and a lot of hope rained down and sprung up. More importantly, a slight runner's high due to the lack of oxygen from working out for so long. To put it simply, he was on a roll.

　-- and as a result, I slurred a poem.

　As soon as I did, the magic of my body stirred.
　It was as if he had heard the poem for the first time, like innocent children frolicking.
　Each particle of magical power bounces and dances.
　Moreover, it also swells its volume.

　I know exactly what it means.
　The poem I've just written and my life up to this other world (here) have become my "compensation" and the world has returned my "achievement" to me, as if it were a reward for me.

　The vision that had reached the entire garden finally allowed me to see beyond the physical walls and into the interior of the towers.
　The people who live in this Hoozeyer's Castle. I see the faces of each and every one of the Knights of Steel, who just a few hours ago had been symbols of fear. Inside their full body armor, they are grown men everywhere. Relieved by that, I smile in the midst of the expanding dimensional magic.

　Let's be honest.
　I'm having fun.
　It's fun for me right now.

　In this "other world", I'm using "something magical" to control it at will.
　If I didn't enjoy this, I don't know what I would have enjoyed about the game until today.

''Hmph, hahahahaha!　Hahahahahahahaha--!

　Naturally, my smile grew bigger and echoed throughout the garden.
　Sis-san comes running up to me. It seems that what I just did was the first time he had seen me go there, and he looks quite excited.

''--Kanami, how did you do it!　Now "Demon Poison" is a great thing!　I mean, what the hell was that?　What the hell?!

　However, my excitement doesn't last long when I'm asked for details again like this.
　When I come to myself, this is a bit...

'Let's see, this is ....... Well, it's a poem, as we call it in our world: ....... Well, it's a magical 'chant' ....... I call it 'chanting'. The current series of 'witchcraft'.
'Chanting'!　Now that's called 'chanting'!　Great!　So this is what 'witchcraft' can do!　That's an idea we never had without a human heart!

　But the embarrassment I felt was blown away by Sis-san.
　She takes it as it is and praises me squarely.
　On top of that, she imitates me like a child and even tries to 'chant'.

'Well, 'Lost to Aeka' and 'Past, Time ......--Continued, what was it?'
'Nay, my old home, my sorrow,' and 'All for the blessing of new beginnings.'
-- "'Lost to Aeka', 'Past time, nostalgic man, sorrow', 'All for the blessing of new beginnings' --!

　Without changing a single word, Sis repeated.
　It's not just a matter of time before you'll be able to get your hands on it.

　However, the amount of that magic power doesn't change much even after finishing the 'chanting'.

''That ......?　Not so different: ......?　Kanami, why do you want to go to ......?
Maybe, but ...... this isn't just a 'price' to pay for saying it. I wondered if it wouldn't be a beautiful 'spell' without the heart to offer what was in that poem ...... to make a deal with the world.
'Hmmm... ......?　So you're trading two at the same time: ......?　Kanami is already negotiating that complicated: ......!　I'll try again: ......!　Well, the words just flew out again. Well, what was it? It's cool, but it's kind of hard to remember.
'Wait a minute. I'll write it down on the ground now: ......

　I write the words on the ground in the garden with my foot.

　'Lost to Aeka', 'O past, time, nostalgic home, sorrow', 'All for the blessing of new beginnings', and after 'All for the blessing of new beginnings', I also add, as a reminder, 'Thinking of the past and those I once lost and loved, I hope and cry out strongly'.

　As he looks at it, Sis tries again, but in the middle of reading the note, he becomes calm.

'U....... I'm not going to be able to make this 'cost' work for me. Because I don't have a past. You can't negotiate with what you don't have. Hey, Kanami. Do you have a better 'chant'?
''Hmm. Even if you call it a good 'chant', I don't think you can make it into a 'chant' unless you know Sith-san well. This isn't just a list of token words ...... because, you know, it comes from the heart.
'Mind, or ....... Well then, it's no use. Too bad ....... But you'll have a private 'chant' for me soon. I promise!
...... Yes, I promise. Right now, Yotaki is my priority, but someday, I'm sure.

　I nodded vigorously and wrote this promise in my mind's notepad that I would never forget it.
　I thought to myself that I would be willing to prepare as much as I could for this Sis-san.

　And the two of us smiled at each other harmoniously - only to find the jit-eyed Yotaki glaring at me next to him.

''Brother ....... Do you know what you're doing right now?
'Eh, what: ....... I'm trying to make the 'spell' of this world more my own--
'He's trying to trick the innocent and naive Sith into turning them into his colors. There's nothing worse than being a bad guy.
'No, no, I didn't do that!　We're just giving each other regular advice!
Huh. How about ......?

　She's treating me like I'm a bad guy who's trying to seduce Sith-san.

　I didn't think that was true, and I was going to ask Sis-san herself to deny it, but she was repeating the 'chanting' that she should have given up on earlier, a little farther away. With a bang and a weird pause, 'All for the blessing of a new beginning! And then he exclaimed, "Hmmm, that's not going to work. Heart, heart, heart. I'm muttering to myself, "I'm going to celebrate poetry with people's hearts: ......".

　I'm already obsessed with my idea of 'chanting', too. ...... Honestly, at a glance, it looks like a university student's gringo sister is bothering her with her junior high sickness. I'm not sure I've ever seen such a thing.

''Hmm ....... Well, I think 'chanting' is a really useful technique, so I think it's somewhat ......
'Yes, you want me to have some of my own colour, don't you? I'm happy for you, brother. I've found someone who understands the hobby that I didn't have in my original world. And the person you're dealing with is a newborn super beauty. You were able to imprint all you wanted. Ah, truly brilliant.
'And a lot of thorns. ...... or is it just born, after all?

　I had a hint of this, but I didn't ask deeply about it.
　It was about the history of the three people who claimed to be apostles. Yotaki, who was summoned ahead of them, seemed to know that.

''Yes. It's a good thing that you're able to get a good idea of what you're looking for. But each of them is pulled by their own figure, so there seems to be a difference between them.
'All three of you are ......!　I thought only Mr. DiPlakula was different: ......
'Diprakra's sensibilities are quite strange, too. He behaves in an intelligent manner to match the old man's appearance, but don't be fooled. That too is unfinished. He's still learning about people.
'I see. ....... No, but I'm sure Mr. Diprakra is a calm and kind person ......

　If it wasn't for Mr. Di Prakula, we would have spent twice as much time talking today.
　It's only because of his concern that I am able to calmly focus on my training now.

'You're ....... My brother is right. He's certainly the calmest and most kind-hearted person I've ever met.
''Yeah. We've only talked for a little while, but I thought he had the right personality to trust Yotaki with it. Much more so than some of the adult doctors I've met in my former world. ......

　I don't blame the doctors who had to deal with so many patients, but there's no doubt that we siblings in the original world were smoking hot.
　At least Mr. Diprakula has treated Yotaki as a bloody individual rather than a number of patients. He's trying to heal me with a sense of mission, not a job.

　That's why I sincerely felt that I could entrust Youtaki to her.
　I could afford to take my time to do something as leisurely as training. But--

'But I can't rest on my laurels, leaving everything to Mr. Diprakra alone. As long as there is something I can do, more ......!

　Ending the chatter, I meditate again and concentrate on the "magic".

　I've become the one who steals the logic of the dimension, and now my "qualities" are sufficient. Through "Chanting", it was also confirmed that "Demon Poison" could be transformed into anything.

　With the definition of the word, the image has become stronger and more confident.
　Up to this point, I had been skeptical of the apostles' explanations, but now I can only believe that everything is real and inevitable.

　Now I am 'the one who steals the reason for the dimension'.
　I'm not going to be able to get the same kind of results as you.

　--I'm not the one who steals the reason of the dimension, not the one who steals the reason of ■.

　That's why I can do it.
　It's not just the apostles. I can meet Yotaki's expectations as well.

　I'm going to create a spell to cure that illness right here, right now.

　Thanks to Mr. Di Prakula's help, we now know that the cause of the illness is the Devil's Poison. I don't know how it works, how it works, and what kind of phenomena it causes, but I'm certain that the evil is caused by the demon's poison.

　Then, we need to replace all the "demon poison" in our bodies with something else.
　Of course, it's not something dangerous like cold air, but rather something positive.

　For example, if you want to convert the "evil poison" that is currently accumulating in my body...

'Ho, that makes really good sense. Your brother ....... Honestly, it's a lot different than I had planned. I wonder if he's more of a healthy average person ...... than a sickbed genius?

　While I use my body for trial and error, Sis-san and Yotaki have a conversation.
　Due to the nature of my 'dimensional power', all of that conversation reaches my ears.

''I said it properly, right?　He said his brother is also excellent. I also said that he's good at this kind of thing because of his assumed nature. ...... Above all, your brother is a person who can push the envelope when it comes to meeting someone's expectations. That's the only thing I am no less than I am. Yes, your brother is never less than me. He's the coolest brother in the world. Without a doubt.
'You're expecting so much. ...... But is that the only reason why Vortex Wave is so good?　Maybe 'witchcraft' is more about the weak than the weak. And I've heard that the world wants to save the weak more than the strong.
...... Yes, that's right. I think it's the result of all those different elements meshing well together.

　I overheard their conversation and accelerated the image.
　There are more things I want to try.

　--Strength is power, but let's convert it into 'human vitality'.

　The image of converting 'demonic poison' into human vitality.
　And not only convert it into fuel (energy) such as energy and stamina, but also into the body itself.

　First of all, the "demon poison" that permeates each of the cells is converted into its counterpart.
　Of course, they are not exactly the same thing. If you do that, the cells that have been doubly existed will interfere with each other and rupture in the body.

　It can't be a substitute for the ordinary (just).
　Blood and flesh built with a higher level of 'something magical'.
　A cell that can replace skin, flesh, bone, blood, or nerves - ideally a cell that is flesh and blood but 'has no mass as matter'.

　It is not bound by normal reason. This is an 'alternate world', and I'm a 'stealer of dimensional reason', and since I'm using 'witchcraft', I assume that I can do it.

'Okay, ......!　Now you can go to ......!

　Thus, I succeed in a slightly dangerous experiment with my own body: 'The amount of muscle in my body hasn't changed, but I'm going to increase my muscle strength'.
　If I had to describe it in words, of course--

"STR (strength) has gone up by 1. ......!　Next time--

　We will re-experiment to see if other complements are possible.
　If we can convert the "demonic poison" into endurance, it would be ideal for curing diseases.

　Other than that, it could also be immunity. Immunity, instantaneous force. Speed of nerve impulse. Enlargement of brain regions.
　There are so many human functions we could increase.

　Just stay focused.
　We can do this.
　If that's the world you want to live in, then let's do it--!

With an image that enhances a person's VIT (vitality), ......!

　I converted all of the 'demonic poison' in my body into a person's ability to live, in the sense of the initial point allocation that I do in game character makeup.

　There was no stagnation in that process.
　With the confidence that they could do it, they converted the "demon poison" without any problems at all.

　-- during the process, I suddenly lose focus.

　I felt strangely light and an exhilarating feeling ran through my head.

　I opened my meditated eyes and lightly slapped my palms together.
　Poof, there was a loud sound. Followed by a strong impact that reached my bones.

　Clearly, I was no longer normal.
　No, my body remained normal. Nothing has changed.
　But within that body was my new strength. That power is helping my muscles even though it's not muscle power. Cells that have no mass as material," constructed with "something like magic," overlapped with "cells that have mass as material" and assisted the movement of my body.
　It shows.

'Ha, ha, ha ....... It's like a game: ....... And then you can give this to Yotaki as well .......

　I want to try it on Yangtaki.
　But I'm not confident that I can successfully perform the same 'spellcraft' and stop.

　It's a difficult thing to do when asked to do the exact same image.
　For now, I mindlessly move my toes and start making notes on the ground, trying to make a summary of the steps of the image.

　-- 'flesh', 'cell', 'copy', 'immaterial', 'penetration', 'assistance', 'muscle', 'strength', 'speed', 'cleverness', 'transformation' --.

'Yeah, it's a 'conversion'. ...... Let's just call this process 'artifice' for now.

　I follow the same 'magic formula' as the memo and perform the same 'spell'.
　I will continue to improve the perfection of the "magic formula" until the remaining "magic poison" in my body is empty.

　Over and over again ...... until you are absolutely certain that it will be the exact same 'spellcraft'.
　And then, after a few tens of minutes--.

Okay.

　I get a feel for the completion of the "art form" of "spellcasting" that replaces the "demonic poison" with "cells that have no mass as matter". I immediately ask my mentor, who has been watching me, to evaluate the new "spellcasting technique".

''Sith-san, please take a look. I need confirmation that it's safe.

　Sis-san, who was talking to Yotaki, was surprised when he suddenly spoke to her and asked us back.

''Yeah, what do you mean you made it?''
It's a 'spellcraft' that transforms 'demonic poison'. It's a 'spell' that makes you transform the 'demonic poison' into a 'human life force' instead of just converting it into a 'predisposition'. Perhaps this is perfect.
Yeah, yeah?　Already ......?　It's not even half a day old and it shouldn't be that easy: ......
'So I want you to take a look. I'm not comfortable using it on Yotaki all of a sudden, so you can go to ....... By the way, I've decided to call it a spellcraft 《level up》.

　I spoke quickly, rushing Sis.
　I wanted her to see it right away.
　More than just for Yotaki, I wanted to show off what I had just created.

　However, Sis-san, who was unfamiliar with my world, didn't seem to be able to grasp the image of the game terminology well. Like me, who was listening back to the words of the other world earlier, I questioned the meaning of the words.

''Le, lebeluap ......?　What is Rebel Up?
"It's a 'spell' of imagery that consumes 'demonic poison' and replaces it with 'human life force'.
Hmm. ......?

　Since it's hard to get them to understand, I thought it would be faster to show them the actual 'spellcasting' rather than explaining it.
　The last remaining 'demon poison' in his own body in front of him is transformed with 'spellcraft'.

''Brother, level up is ....... It's already completely .......
'I was most confident in this one. If it's as Sith-san explained, this imagery method is for me. --Cursery [Level Up].

　Before I can stop it, I speak the name and activate the "spellcasting".
　Of course, what follows is a "chant" that assists the "spellcasting".
　It's an original 'chant' exclusive to this.

"-- 'Thou shalt scrape and reflect,' 'Know the brightness of its life,' 'In me, in thee' --

　This time, what I'm going to 'pay for' is my own 'demonic poison'.
　By following the proper procedure, I will convert it into 'human power' instead of 'dimensional power'.

　At the same time as the 《Level Up》 succeeds, my body begins to emit a faint light.

　The ominous, dim 'Demon Poison' has turned into particles of light. And that radiance seeped into my body and disappeared.

　Seeing this appearance, Sis-san opens her mouth wide in surprise.

''--!　Soooo, awesome ......!　The 'demonic poison' in Kanami is all gone: ......!　Instead, some kind of presence?　has increased in strength ......!
''Even from my eyes, I can see that the bad stuff has disappeared from your brother's body. Isn't this already the solution to this world's 'demonic poison' problem?
"--Hey!　Come on, Kanami!　Let's see if that can be done by anyone other than Kanami!　It's called that spellbinding Reveruup!

　Sith-san hurriedly urged the use of 'spellcraft'.
　The means of removing the 'Demon Poison', which was the Apostle's primary objective, had fallen and sprung up. I can understand your excitement, but if possible, I would like you to be a little calmer in your assessment.

'Well, Sith, you can go to ....... What do you think of the current 'witchcraft': ......
'Nothing to worry about!　It was a very beautiful 'spell'!　I can already admit that Kanami is more than me!

　Rather, it seems that before I knew it, I had surpassed my mentor, Sis-san.
　Even though the beings called for this are us 'Gentiles', I didn't expect that I would surpass my master so quickly.

　In other words, spellcraft 《Level Up》 was no longer in Sith-san's hands.
　The responsibility for this can only be taken by me, the one who developed it.
　Naturally, a hesitation arose in my chest.

　However, Yotaki took my hand and

'Brother, please. I believe in you.

　It dispels all my fears.
　There was no longer any doubt in my mind.
　I'll get right to work.

"Alright. Then let's go, youtaki. --magical trickery.

　The image of that spell is the same.
　But this time, the target is different.
　It's another level of difficulty to work on someone else's "demonic poison" instead of your own, which you know very well. Even if you imagine a single cell in your body, it's too different.

"-- 'Thou shalt scrape and reflect,' 'Know the brightness of its life,' 'It is in me and it is in you' --!

　However, when the surgeon is me and the subject is Yotaki - I don't have a single concern.
　There is no two people who know each other as well as we brother and sister, who communicate with each other's feelings and are as close as we are.

　I'm going to strengthen the power of that "spell" through "chanting".
　All of the 'Demonic Poison' in Yangtaki's body will be converted into 'Human Power'. In particular, I will focus on increasing your vitality and strength, and increasing your immunity to all kinds of diseases...

Shh, ah, ah, ah!

　But halfway through, Yotaki's scream went up.
　I was surprised to see that she didn't have a radiant expression like I did, but an anguish floated on her face.

　Now, my spell, Level Up, has been activated and the "Demon Poison" in Yotaki's body has been eliminated.
　And yet, Yotaki bends to his knees.

''Sh, you failed ......!　Yangtaki, I'm sorry!　Are you okay!

　Immediately I ran to Yotaki and supported his body.
　Sis-san followed behind me. But instead of worrying about Yotaki, I observed the changes in her symptoms in a close manner.

''Vortex waves, it's not like it's a failure. Yotaki's 'demonic poison' is properly gone. But it doesn't look like it's been resolved. ......
Gone?　Why ......!
'Look closely. ...... Thanks to the disappearance of the 'demonic poison', the cause is a little easier to understand.

　Sis-san asked me to make a calm observation as well. I understood that this was the most necessary thing right now, because I had used the 'spell' technique.
　I switched my mind from the family to the doctor and tried to understand the situation.

　I examine Yotaki's body.

　Ignoring the expression of anguish, I measure the amount of sweat sticking to the skin. Grabbing his wrist, he knows his body temperature and pulse rate, and finally, he uses the "dimensional power" of the example to see through Yotaki's body as well.

　The 'Demon Poison' inside his body was empty.
　This place was as expected.
　However, Yotaki is suffering.

　If there was a big difference between this and the previous one, it was the movement of the surrounding demon poison.
　Youtaki's 'Demon Poison' suction has become much stronger. Like a dry sponge, Youtaki's body is trying to suck in the "Demon Poison" contained in the surrounding air. The emptying of the air seems to have activated the suction.

''Apparently, Yotaki's symptoms seem to be the biggest problem with getting in and out. Is it due to his vessel being too big, unlike the others?　No, I wonder if it hurts simply because there are so many fissures in the vessel, coming and going.　Hmmm ....... I see.
'What's the cause of the pain coming in and out ......?　So, if you prevent them from coming and going, you won't have any pain in Yotaki's body: ......?　Then--!

　I see the next problem and try to create a new "spell" to solve it right away. But Sith-san stops me from doing so.

'No, Kanami!　First of all, you should focus on your current spellcasting rebel-appu!　Unfortunately, it didn't make sense for Yotaki, but it should work for someone who isn't a sucker!　Wait a minute!

　After instructing me not to move, Sith-san started to run.

'What?　Mr. Sis!　I'd like to solve the Yangtaki one first, but ...... is so fast!　

　By the time I finished replying, her back was already small at the back of the garden. As I was stunned by her shorthandedness that didn't match her thin body, Yotaki called out to me on my back.

''Brother ....... Let's follow the Sith as much as possible now. We already owe him a debt of gratitude for stopping the progression of the disease and saving our lives. With my body, there's still plenty of time to spare, so there's no need to be so impatient.
Even if you say you can afford it, you're in pain: ......
'It's not that much of a pain. Compared to before, it's really ....... Your brother would understand, wouldn't he?

　I know what you mean.
　The current Youtaki's face now is much bloodier than the one she had a few days ago. Considering the critical situation where not a single sweat was flowing, you can say that she has plenty of time to spare.

''...... That's right. I'm in good spirits today Yangtaki. I'm really ...... fine.
Yes, I'm fine. So let's repay the girls first for the favor they've given me by making me feel better. As for my detailed treatment, it's not too late to think about it afterwards.

　Yotaki is trying to keep the give-and-take protocol tightly in place.
　Since you gave it to me first, it's my turn to give it back.
　He's expecting me to be honest, which is a natural part of being a human being.

　So even though my frustration was stuck in the back of my throat, I couldn't let it out.
　As long as Yotaki himself insists that it's okay, it's just unnecessary meddling for me to move on my own here.

''Okay ....... If Yotaki says so, then you can go to .......

　I relaxed from my body and nodded back wordlessly.
　Yotaki saw that and smiled.

　While looking at her sister's smile, I doubt it in the corner of my mind.

　--Really (...)?

　I know my sister's acting ability better than anyone. Even if she was in pain as bad as a broken bone, she would be able to smile like she does now. On top of that, she's the kind of girl who would carry the pain alone out of consideration for others.

　I have a criminal record of not realizing the seriousness of Yotaki's illness until she was in a fatal condition.

　--I can't be relieved yet. I won't be tricked by Yotaki again.

　As I swear to myself that I won't be tricked by Yotaki again, Sis-san returns from deep within the garden.
　She's back earlier than I expected.

''Vortex wave, Yotaki!　He's here!　The next test subject!　It's just nice to be around!

　Mr. Sis runs up to us, holding one of the girls in his arms. He then set the girl down on the ground in a messy manner and stretched out his chest.

　The girl who was carried around like a package looks confused and scurries around.
　Looking at the girl, the first thing Yotaki does is roll her eyes.

''Si, Sis ......!　Isn't that person the princess of this castle ......?
'Yes, but ....... So what?
'Trying the newly created 'spellcraft' against a princess is a quintessential ......

　I recognized the face of the girl who was called the princess.
　Her long, shining hair, which was neither white nor yellow, hung down, and she was wearing two thin layers of clothing. Without a doubt, she is the girl I met at the top of the tower when I just came to the "Other World" today.

　I say the name I've just learned.

"'Tiara' ......?

　When the girl hears this, she shakes her shoulders strongly and then stiffens up.
　Then she looks at me and says her name, which I'm sure she has just learned as well.

"'Kanami' ......?

　The moment she recognized me, Tiara stopped moving right and left and hid behind my back with a sluggish movement.
She seemed to be wary of Yotaki, who was meeting Sis-san for the first time, who treated her like a piece of luggage.

'What ......?　Brother, do you know her?

　Naturally, Yotaki expressed his doubts.
　I guess he thought that my acquaintances in the 'other world' were none other than the Apostles.

'Yeah, oh ....... I met them when I wandered in here and was running away, and they helped me out a bit. I heard his name was Tiara. ......
...... Heh.

　A single word in a pout, Yotaki replied.

　He didn't say anything else. He just stared at me - and at Tiara - and stopped moving, thinking about something.

''Come on!　Tiara!　As promised, the "Gentile" I called to save you from your misery - you can't say that in Japanese!　Let's see, the Hoosier's word is ......!

　Halfway through, Sith-san switches languages.
　Then, with muffled words like a spell, she speaks to Tiara, who hides behind me.

''----, ---- --''　'----'!

　I don't know the meaning of the words.
　However, as I listened to the flood-like voice, Tiara's vigilance was gradually lifted. After looking at me with a heartfelt surprise, she slowly exposed her figure to all of us.

''Vortex waves!　I talked Tiara into it!　She's on board!　Here, do it, do it!

　Sis looks at me with sparkling eyes and looks forward to my 'witchcraft'. But I'm not going to take her permission for granted.

　I walk up to the little girl who has come out from behind me and make firm eye to eye contact, exploring her own feelings.

"'Tiara', are you sure you want ......?

　We may not be able to communicate, but the air (nuance) would come through.
　I had confidence in that. After all, until just a few minutes ago, Tiara and I had been talking only by air (nuance) and teaching each other's language. With such a short contact, it should be possible.

"...... 'Kanami'. I believe.

　In response, Tiara looked back at me, placed her hand on my chest, and replied in one word.

　It wasn't Japanese, but it was a language I knew. She used only the words she taught me to express her will.

''Surely,'' she said, ''for this, we have met.''

　Then Tiara stepped forward, took my hand and meditated on my eyes.

　It was a short conversation, but the air (nuance) of trust was well conveyed. Because of the lack of words, I can read her innermost thoughts from her expression and gestures.

　--The only way to get to the top of the mountain is to go to the beach.

　And just as much as I am confused by the strange fate of the relationship with her. It's just that she is the first person I've been able to forgive my heart since I came to this "other world" - I felt like I would be friends with her until my death in the future.

　It could all be a misunderstanding.
　Maybe the meeting was just a coincidence.
　But as I felt the warmth of Tiara's hand on my body, my hesitation became certain.

...... All right, I'll make it work. I'll definitely make it work, Tiara. -- 'Thou shalt scrape and reflect', 'Know the brilliance of its life', 'It is in me and it is in you' ----

　The same procedure was followed again, chanting 'Chanting' and working on the 'Demon Poison' in Tiara's body, which was meditating.

　The process was very smooth.

　The passage of the spellcraft 《Level Up》 is better than when I used it on my sister, Yotaki - or even worse, when I used it on myself.

　It really feels like fate.
　As if to say that everything was for Tiara at this time, it succeeds.

''--Cursery [Level Up].

　After completing the spell, Tiara's body emitted a faint light.

　This is the proof that the "demon poison" has been replaced with "human life force".
　With this, Tiara will no longer have her body irrationally consumed. Every inch of her body was filled with new strength. Her respiratory system, which had been coughing many times, should be stronger than before.

'Tiara ....... Maybe I've made it: ......

　When I called out to her, Tiara slowly opened her eyes.
　Then she looks at me and rolls her eyes at the scenery around her. Next, she looks at her own palms and shakes her body. Little by little, he lets out a sob.

"'Uh', 'Ugh' ....... 'Uhhhh', 'ahhh'--!

　The thought of another failure crosses my mind and I turn to run to Tiara.
　But she runs out before I can get to her.

　She dives into my chest in front of me and embraces me--

"'Thank you' ....... 'Kanami' ......

　I thanked her.
　I lowered my gaze to check her face and I was relieved to see her face.

　Tears were spilling from both of her eyes, but I could tell from her smile that she was not in pain. I've never had to deal with illness in my life, so it's hard for me to imagine, but I can at least sense that she is filled with unstoppable emotions.

Yes ....... 'Good.' ......

　So I have a word for you.
　With the words I just learned, I congratulate you on the release of the tiara.

"'--- (・・・・・)' ....... '------ (・・・・・・・・)'

　She looked up and replied in a language I didn't understand.

　Her ears and nose are bright red and muffled with tears, but she has a big smile on her face. I'm sure it's a joyous word from the bottom of her heart, without any decoration.

　I rejoice at that as if it were my own business, and Sis-san smiles as if it were her own achievement.

''Hmph, hahahahaha!　We did it!　It's working!　Not a huge amount, but it sure does!　I've got normal human circulation!　Once again, thanks to me!　Not Diprakra, you Sith!　Hmph, ahahahahaha!

　Next to him, Yotaki is patting his chest.
　With a very deep sigh, the deepest sigh of the day.

''...... haha. ...... I was a little nervous, but I'm glad I succeeded. After all, it seems that my brother's 'spellcraft' was perfect. It was my body that had the problem.

　From a sister's point of view, it can be seen that she was a little bit opposed to casting a 'spell' on the princess that hadn't been confirmed as safe.

　But in the end, it ended up being a great success.
　The human beings in the other world whose bodies had been consumed were returned to their proper state, and the total amount of "demon poison" in the world was reduced, albeit slightly.

　Now I have the first success in my heart.
　A lot of things have happened, but we've made great progress in just one day.

　Perhaps the crisis in this world will be solved soon.
　The next step is to find out what happened to Yotaki's body. This one will also be solved in a few months, and we may be living a happy life with smiles on our faces in a year's time... I smile, thinking of a faint dream.

'Haha, thank goodness ....... Haha, that was really, really good ......

　I was feeling a little dreamy.

　It was understandable.
　In just one day, my world was repainted too much.

　I can't believe I was called to the 'other world', my sister's life was saved, I met a princess, I was able to use 'magical things' and I walked the first step in saving the world. ......

　-- honestly, it's too good to be true (・・・・・・・).

　But that doesn't mean we can't deny Tiara and Sis-san who are rejoicing. There's no way I, as an outsider, can say that Yotaki's improvement in physical condition is a lie.

''Thank goodness ....... Hahaha ......

　Thus, I am as usual.
　Scared that if I ask, it might be the end of the world, and I'm still unable to ask what I really need to ask.
　I'm leaving the world that didn't work and starting a new life in a completely different world.

　Day one of that story was a beginning with no failures.
　On the first day, the four of us were still--
