"--In their childhood, the brother and sister continued to compete.
　They vowed not to lose to each other and competed with each other as best they could.

　However, the outcome of that battle is ...... already known and understood by 'us'.

　This is a story that confirms what is understood. But, in turn, it makes sense to read (...) without missing a beat.
　The truths that have been taken up all along, now - with "We".


　-- his older brother Uzumi continued to challenge and strive.

　However, it was an effort within the scope of an ordinary person.
　Naturally, there is no way he can compete with his sister, and he is defeated many times.

　Nevertheless, in his childhood, Uzurinami repeatedly chased after his sister, saying aloud that he would not lose to her. With an unusual effort that was not appropriate for his age, he continued to fight, even though his mind was twisted.
　Because if he didn't, the boy, who had been taught by his parents that "victory is everything," couldn't hold himself together.

　--And every time he did, he unconsciously made a deal with the 'break'.

　By paying many 'prices' and making countless cracks, he managed to compete with his sister. Without a doubt, the Aikawa Uzumi of his childhood would definitely be a 'child prodigy'.
　He was the only child in this world who reached for the 'contract' and mercilessly continued to chip away at himself.

　But even that 'child prodigy' was too bad for his opponent.
　It was just that. So.

''-- No one can beat Yotaki (that guy) ....... There was no way I could win against that thing. From the beginning, there was no ......, I wasn't in this house (・・・・・・・・・) from the beginning.

　It breaks completely.

　No matter how much I cut myself off, the gap between me and my sister just keeps opening up.
　His heart finally admitted defeat to that unreasonable reality.

　When he accepts that he will never be able to win back his parents' love from his sister, he utters the words, "It's nothing," and he gives up on fighting -- on living.

　-- this is Aikawa Uzumi's turning point.

　This is the fork in the road where he can say that he has gone completely the wrong way.
　If Uzumi had been able to be a child and be obedient to his father and mother at this point, the story would have been different. But it was not to be. Continually defeated, the boy's mind is warped into a distortion, and he is trapped alone within his own mind.

　In reality, he begins a life of seclusion in his room and not interacting with any of his family members.

　--This is the end of Aikawa Uzumi's childhood.

　But this is where 'we' already know.
　So, the important thing here is not the ending of the older brother, but the younger sister, Aikawa Yotaki.

　At this time, Yotaki was trying her best to respond to her brother's challenge of not being defeated.
　That's exactly what he did everything he could think of so that [no one could beat Aikawa Yotaki].

　Just like her future real adversary (rival), she first laid out a large number of books in her room, opened them and read them.

　She read concepts similar to The Devil's Poison from history and religion, and fished out what she thought could be applied to the operation of The Devil's Poison from psychology and exercise science.
　It was physics that was less useful than I expected, and vice versa, medicine.

'-- Now we can 'convert' ......!　Whatever I want to do. ......!　Phew!

　At this point, Yotaki had mastered something close to 'Level Up', which allowed him to 'transform' the 'Demonic Poison'.
　Furthermore, he had also succeeded in making the 'massless nerve' replicate.

　At first, he was pleased that by increasing the organ called 'nerve', the efficiency of sucking 'demonic poison' would be accelerated.
　However, the discovery of the 'massless nerve' was the fork in the road for Yotaki to be able to say that he had completely lost his way.

　The chemistry was too good.
　It was only when it became unstoppable that he realized this.

　First, I lost control of my suction at all.
　The suction was too efficient, and the 'demonic poison' would accumulate in his body at a terrifying speed.
　Moreover, if left unchecked, some part of his body would become deformed like a tumor. Scales and feathers like monsters in manga and video games grew, which was terrifying to the still young Youtaki.

　He needed to convert the accumulated "demon poison" into some kind of power or talent as soon as possible.
　However, that massive amount of "conversion" work can't be done in time with my current processing capacity. That's why we need to duplicate the mass-less nerves for the conversion. However, if you increase the number of massless nerves, the demon poison will be absorbed even faster. -- a vicious cycle, Yotaki had fallen into.

　However, if one only looked at it in terms of becoming stronger, it might have been a good cycle.
　However, it was a cycle in which he was threatened to become a 'monster' if he stopped just once.

　-- I was scared.

　Even Yangtaki, the sensation of becoming something else was a biological instinct that he couldn't endure.
　Driven by that fear, Aikawa Yotaki's 'massless nerves' grew and enlarged at an accelerated rate. Of course, to match that increase and hypertrophy, further increase and hypertrophy would be necessary.

　Before long, the density of the massless nerves that continued to increase in the body lightly exceeded tens of thousands of times that of an ordinary person. As a result, a thin white line underneath the skin (although only Yangtaki was visible) could be seen. A small web of gaps was stretched out and faintly luminescent.

　And as if to catch up, Yotaki began to be tormented by an extreme headache. It was also supposed to be a headache, but the pain was heavy, sharp, and constantly occurring throughout his entire body, not just in his head--.

-- haha, haha, haha ......!

　If it was still this far, Yotaki could endure it.
　But this wasn't the end. It was too much to expect that his body and pain would reach an unbearable level in the near future.

　At last, Yotaki realized the true nature of himself.
　This 'constitution of sucking 'demonic poison'' is the same as a flooded river. Once it flows out, it cannot be stopped by human hands and is made from the very beginning to swallow all the 'Demon Poison' and become a muddy stream that washes away the world (・・・・・).

　It was the moment when Yotaki changed her perception that 'it' was not an 'innate difference', but an 'innate disease'.

　In other words, she was really a disease, just as she had called herself in the other world. She continued to live with the disease that couldn't be cured, and deep down, she kept wishing that someone else would cure her.

　Finally, a young girl, who has just reached double digits in age, begins to seek "someone" and salvation for the first time in her life.
　She walked all over the house, walking and walking and walking - coincidentally, her mother, who was very busy that day, was at home.

'--Yes. That's troubling. ......

　However, as we knew, my mother would give me a "troublesome" look when I told her that I was lightly unwell.
　An ordinary person would only feel the compassion of the Holy Mother in front of the actress' acting skills. However, unfortunately, Yotaki at this time was far from being an ordinary person due to the increase in 'massless nerves'. The moment her mother stroked her forehead, ''You-taki-chan, this is the first time you've ever said something like that,'' she read her mother's intentions, ''If you can't use it, then I'll throw it away.'' ''If you're in my way, even if you're my daughter--''

'Umm, yeah ....... Just for a moment.

　He was quick to judge because he was originally considered "seedy".
　Immediately, Yotaki shook her head and moved away from her mother.
　Mother would be relieved by that.

　This was the end of the consultation with 'family'.
　It was very short - but Yotaki knew that no matter who he talked to, the result would be the same. There is not a single person in the world who can sympathize with you, including this too much trouble.

　Yotaki had finished confirming the monopoly of this 'demonic poison' by himself.
　Therefore, this joke of a supernatural phenomenon (occult) is my sole concern in the world.

''Huh, hmm--''

　After confirming this, Yotaki can only laugh to himself in his room.

　Then, he imagined alone about himself in the future.
　From now on, this 'massless nerve' will continue to increase infinitely.
　For now, that's okay. But in the future--.

!

　Just as he was thinking about this, he was hit with a sensation he had never had before.
　That was the moment when Yotaki's predictive ability began to become inhuman due to the ever-increasing brain nerves.
　His skills will inform him of his own consequences.


[In the end, one]
【Only one person in the "world".
　Within the frozen city, Aikawa Yotaki stands and smiles as he chuckles.
　An uncommonly cold wind, like the ice age, had completely frozen modern civilization.
　In the midst of a fierce blizzard, only the girl alone survives, and she just keeps laughing--]


　The moment you see it.
　You know intuitively that it's not a lie.

　This is the 'answer'.
　At this time, she had acquired not only a simple 'future vision' but also a 'thinking' type of skill - a skill that would later be called 'the skill to read the book called the world in reverse'.

'...... and I have to stop.'

　Immediately, Yotaki is eager to change its future.

　Fortunately, the 'Demon Poison' is the source of all talents and powers.
　So he decides that the quickest and most rational way to stop the vicious circle of the "massless nerve" is to acquire a talent and power, so he scours the books scattered around his room for science-related items.

　Then, in an attempt to 'still' this vicious cycle at the atomic, molecular, and quantum levels, I took a textbook image - and manipulated the 'magic poison' in my body.

'Please, stop ......!

　Yes, I wished (・・・・・・・).

　Yotaki reached out to her new power, hoping for a scientific response.
　However, what responded to her was a very magical response.

　--a gaze (...) reaches her.

''Eh?''

　The 'slit' behind him looked at Youtaki with pleasure.
　And soon after, the slice presented you with the Demon Poison to make your wish come true.

　It was a massive amount of 'Demon Poison' that was too much to hold. It's not just a matter of time before you are able to get your hands on a new one.

　-- A chill, cold air passed through the room.

　It's not just the windows, but every doorway is closed off. No one has touched the air conditioning system. And yet, an unusual temperature change appeared, and a small, but still small, icicle rose up at the foot of Yangtaki.

''Ko, ice......''

　Without a moment to think about it, or rather, without being allowed to even think about it, Yangtaki found out the meaning of this phenomenon.

　The "contract" that his brother Uzumi had made in the past was now fulfilled for him. And he confirms that a new "massless neural circuit" has been built in his body.

　The ease of the process surprises Yotaki.
　Hoping to stop, his feet froze underneath him.
　I almost put the room on ice.

　By comparing it to the 'Future Ice Age' that I saw earlier, I know another 'answer' in advance.
　That's the 'answer' of [I'm going to head towards that end in an attempt to stop me].

'Oh, no, it's not that: ......'

　In other words, you are not even allowed to wish for 'stop'.
　And even while he understands that he is now in an impasse, the 'demonic poisons' from all over the world are constantly gathering towards Yotaki, forcing him to 'convert' to prevent deformity.

　Wherever and whenever, without limit, Aikawa Yotaki would become stronger and stronger.
　Such a flow has been made.
　Exactly as if [no one can beat Aikawa Yotaki], in a situation where the 'world' is cheering for her--

"...... because that's what I wanted?　No, but it's not--

　I'm confused.

　In the first place, [No one can beat Aikawa Yangtaki] was a child's unique and poor wish.
　Normally, it was a wish that was too juvenile to ever be fulfilled.
　However, Youtaki had the capacity to do so.
　It's not just a matter of time before you're born.

　-- that's why it came true.

　Understanding that -- no, with his newly acquired skills now, Yotaki was forced to understand it, and he backed away.

　The icicle he had created in front of him was terrifying. However, by taking a step back, he could see the one truth he had been turning away from.

　A white frost covered his own legs.
　He could have gotten frostbite. Despite this, Yotaki was not inconvenienced by the cold at all. Although he was frozen, even his fingertips could move as he wished. It's not that he doesn't have any sensation, or pain, or that he can't tolerate the cold - it's an anomaly (...).

　Until today, Yotaki has never suffered an injury that seems to be an injury.
　I've never confirmed it.
　However, he is riddled with 'answers' with skills.

　[Even if Aikawa Yotaki is injured, he will be forced to heal].

　Under the condition that there was an excess of "Demon Poison" and as long as he hadn't lost his constitution, I intuitively knew that it would be automatically repaired.

　Therefore, even Yangtaki's leg, which had just receded, would soon be healed.
　In the blink of an eye, it was back to its healthy bare feet.

　Yotaki trembled in front of that extraordinary scene.
　It's too inhuman.
　That's why I wonder.

　Could it be .......
　Really, it's a metaphor, but .......
　Even if Aikawa Yotaki committed suicide, dying--, the 'answer' of [not dying] immediately interrupted his thoughts.

''--!

　And then I say to myself.

'Mo, no more ....... Don't wish, don't wish any more ....... Breathe shallowly and minimally--

　Next, stop thinking too.
　It was the only way to reduce the occurrence of "transmutation" and "contract".
　The pain caused by the increase in "massless nerves" also faded away by diverting your consciousness. Although it was a symptomatic treatment and not a fundamental treatment, Yotaki found that it was the best for the current situation.

　However, his head is inevitably heavy.
　Due to the incessant pain and the skill of always having only the 'answer' in his head, his head was heavy anyway.

　Yotaki experienced hardship and hardship for the first time in her life and resumed her life - but even though her head was this stagnant, she still remained a Kirin child from the outside.
　Not only did she struggle to live a normal life, but she was no less than someone else as a child actor. It's because her specs as a creature are fundamentally different.
　And that was the proof that he was gradually becoming less and less of a 'person'.

　So, at this time, Yotaki was already--.
　Is there a device (me) alive that can control the "Demon Poison"?
　Is there a device (me) alive that can transmute the "Demon Poison"?
　I'm not sure.

　--That was the end of Aikawa Youtaki's childhood.

　At the same time as her brother, she too was in deep despair. She unconsciously made a 'contract' and at the fork in the road, she 'took a complete wrong turn'.

　--This is the end of the brother and sister's childhood.

　This is the end of the brother and sister's childhood, and from this point onwards, it will be the boyhood and girlhood.
　They have finally grown up to about 10 years old, and both of them are on the verge of reaching their mental (or emotional) limits.

　Although my brother would never admit it, these siblings were truly alike.
　That's probably why.
　Instinctively, the younger sister had asked her brother for help.

　All kinds of 'answers' kept popping up in her head due to her skills, and she kept one 'promise' in her heart even when she was unable to give the 'answers' she really wanted.

　If he can help me, it is only "my brother, my sister" and "I have no 'family' other than my brother", believing that - with my head heavy and aching, not knowing what to wish for, and keeping my thoughts to a minimum, wandering into my brother's room from my room, what It happened several times.

　Without knocking, Yotaki walked into his brother's room like a ghost.
　However, even if their eyes met, there was no greeting or even a word exchanged.

　At this time, Yotaki was being ignored by his brother.
　This was because Uzumi couldn't hold himself together except to erase any contact with his family due to the trauma of repeated defeats. Even if Yotaki forced himself to pack up, Uzurinami would be so traumatized by the trauma that he would go into a frenzy and not be able to have a proper conversation with him.

　So, it was an unspoken agreement that they would be each other's 'non-existent' ones.

　Both of them had a lot to say, but they just stayed shoulder to shoulder.
　The older brother turns to the screen and begins to play the game by himself.
　Next to him, his sister continues to stare at the screen as well.

　On the screen is a high street role-playing game.
　Uzumi doesn't like oddball games. The more effort the 'hero' put in, the more results he would achieve, the more people around him would praise his efforts, and he liked games that promised victory in the end.

　Inevitably, swords and magic would be the subject matter of the game.
　It's very fantastical, there's a concept of levels and stats, and the spectacle of fighting monsters is on the screen.

　Uzumi was so engrossed in the game that he couldn't see anything but the game screen.
　Yotaki didn't hate watching his brother.
　Most of all, this was the only time--.

...... Today, it's another fantasy RPG.
...... Yeah.
Your brother likes to play games with magic, doesn't he?
'It's like ....... The magic in these games only becomes available as you level up. This has nothing to do with the player's talent or anything else. Maybe the speed at which you learn it won't change much if you do. Maybe it's because it's .......

　It became a conversation.

　There were many reasons.
　But the biggest reason was that Yotaki liked the world of the Royal Roads Role Playing Game where everyone was equal, just as much as his brother did.
　His brother also admitted that his love for it wasn't a lie, and he allowed himself to stand shoulder to shoulder with his hated enemies in this way.

'I see. ......'
'Oh, yeah. ......'

　They answered each other briefly and the conversation was over.
　Any other topic of conversation would be too much for his brother to bear, so Yotaki looked at the screen again.

　Of course, the story of that royal role-playing game is obvious even before you complete it.
　There is a 'hero' who will one day become a great hero, a 'heroine' to support him, and at the end of the 'adventure', he fights a powerful enemy and has a happy ending.

　At the end of the adventure, the heroine fights a powerful enemy and comes to a happy ending. On the other hand, the "hero" spits out some unnerving lines like, "Even if you make the world your enemy, the heroine will save you.

　Uzumi repeats that same kind of story over and over again.
　He puts himself on top of the "hero" and always clears it up in earnest.
　In other words, the harder he works, the more he tries, the more he achieves, and the more people around him praise him for his efforts, and he's always hoping that in the end, he'll be promised victory--

Oh.

　It was a game over screen.
　Uzuraha let out a pitiful voice as he lost the important last battle.

　After a few moments of silence, he looked at Yangtaki next to him with a bit of embarrassment, and then he slowly loaded the data and tried again for the final battle.
　Then, after an hour or so of fierce fighting, Uzurinami sees the emotionally invested 'protagonist' saving the world, and with a sense of satisfaction, he gets to work on the next game.

　Yotaki was watching it behind him - with one simple question in his head.

''.............''

　What will happen to the world after the game over earlier?

　There was no continuation to the game. It ended at the game over screen.
　But before that 'last enemy' fought the 'hero', they had talked about some ridiculous future plans like 'crushing all futures and turning everything back to nothing' or 'continuing to eat the world and live forever'.

　Yotaki is curious about the story after they have won that.
　Of course, no matter how much he thought about it, there was no way he could get an 'answer' as long as there was no continuation prepared for the game.

　It can never come out.
　There is no continuation to that story.

　That's what Yotaki wanted to believe - but he was shown.
　Soon, the "answer" will be visible to you.


【--Aikawa Yotaki is the only one who has finished the final battle and is now alone.
　The "world" was frozen and destroyed, and all living things were turned into ice sculptures.
　No one can defeat Aikawa Yotaki.
　Above all, this situation was Aikawa Yotaki's innate mission and role.
　Having sucked out the "demonic poison" of the "world", Aikawa Yotaki continued to survive as the "last man". And before long, he will have no choice but to go on a journey.
　In the next world as well, she will absorb all the demon poisoning from her natural mission and role.
　And the same thing will happen in the next world. The next "World" will have exactly the same ending. Aikawa Yotaki is alone and will continue to rotate through the "World".
　Forever.
　Forever and ever and ever and ever, alone in "The World" --]


　The game I was supposed to be enjoying as an escape from reality is the catalyst, and I see the rest of my endings that I've been avoiding.

　Fear seeps like oil.
　Anxiety spreads like a flame.
　My head, which is already full of it, is filled with negative emotions.
　I'm afraid of that future. It's just so scary and frightening -- because even though he tries to pay it off, his head keeps creaking, heavy and painful all the time -- he can't help it, and Yotaki looks at his brother.

　--Even though he tried to stop thinking, that 'promise' was the only thing that came to his mind.
　--I realize that there is no more form, it was just a passing of the time.
　--I also feel guilty that my brother's current condition is my fault.

　Still, Yotaki wishes.
　It was a reflex, not something that could be stopped by his own will.


【--No, I'm not alone.
　The two of them are going on that 'eternal' journey.
　Next to Aikawa Yotaki, there was always a 'family' next to her that loved her in the true sense of the word.
　At all times, always.
　Because it was the two of us for a long, long time, 'forever'.
　There was nothing to fear anymore--]


　Yangtaki wished and the ending of the story wavered.

　The "answer" was simple.
　If there is someone who is an "equal", all problems will be solved.
　The worries you have had since childhood, the fears and anxieties you have now, are all there.

　It's a good thing that there's just one more person - so in your ear, Yotaki kept whispering to you all the time, and that 'answer' was annoying and unbearable - but it was so simple and clear that you could not help but love it! So, in the end, you end up asking for it.

"Ni, brother--

　My brother.

　It was a given from the beginning.
　And then, for the first time, I'm going to talk to him about my problems.

'If ......, it is if. If you could use that magical kind of power, what would you do, brother?

　If you ask me that, Yotaki knew with his skills that his brother couldn't ignore him.
　So this wasn't an invitation, just an act of dragging him in.

''What?　Magic, because ......?　What the hell did you do to deserve this?
If you could use it in real life, would you want to use it, brother?
............. ...... lies.

　Unlike Yangtaki, Uzura Wave was not crisp.

''I'm not lying,''
'Lies and ......, of course ......'

　Magic.
　Because Uzurinami had always been passionate about the fantasy game - but not because of the trauma of his childhood, which made the unreasonable and ridiculous word "magic" seem real.

　To Uzumi, Yotaki's talent could not be explained if it wasn't magic.
　On the contrary, there were many aspects of magic that would have made sense in defeat.

　Using Uzuraha's trauma, Yotaki - fascinated.

''You'll have to watch.

　First, Yotaki manipulated the temperature in the room to lightly create an icicle.
　Next, he used his 'massless arm' to move things he hadn't touched.
　He showed the power of all sorts of 'demonic poisons', from practical psychic-like things to fantastic things that just looked good. And my brother, who was fascinated by it.

'...... ha ha. ...... ha ha.

　Laughter.
　The response was that he had to laugh.
　And then, very sadly, he mumbled and admitted, pensively.

'What's that ....... What the hell, that's ......!　Ha, ha, ha, ha ......

　I forced myself to keep laughing and hung a paragraph.

　Just like in my childhood, I felt deeply defeated, overwhelmed by my sister's abnormality.
　This time, however, it didn't end with despair. It was partly because he was beginning to get used to despair, but the word 'magic' was just barely holding his body together.

'You're going to tell me that, ......?　You?

　Following Yotaki's guidance, Uzurinami spat out those words without any shame or outward appearance.

''Of course. If it's your brother, you should be able to use it. ...... because we're 'brother and sister'.

　Yangtaki agreed and immediately explained about the 'Demonic Poison'.

　Using this, it's not impossible to make magic like a game.
　Suggesting that, he begins to train his brother, trying to drag him into the same realm as him - but things don't progress that easily.

''--Crap!''
Calm down, brother: ......
...... You were born with this?　Really?
Yes ......
"...... d*mn it.

　Youtaki had hoped that his brother, who had performed the 'contract' before him, would be able to learn it quickly.
　However, the reality was that he couldn't even feel the 'demonic poison'.

　Vortex Wave couldn't even do what he was told to do, "It's the basics first," and he swore in frustration many times.
　He still had faint expectations somewhere in his heart.
　Even if he was inferior in the field of practical studies and entertainment, he had the last hope that he might be able to use it better in the field of his specialty, which involved games.

　With that hope shattered, Uzurinami clenched his fists so tightly that his skin split open and mocked himself.

''Haha ....... In other words, it's just another innate talent ....... Talent, talent, another talent wall .......''

　He laments his own lack of talent.

　However, in reality, that perception is wrong.
　Aikawa Uzumi is better suited to 'Demon Poison' than anyone else. Not only is he not talented, he's the best qualified person in the world. Even if all of mankind were to compete against each other under the same conditions, he had the talent to be able to manipulate the 'Demonic Poison' before anyone else in this world.

　However, he had the wrong person to compare it to.
　What Aikawa Youtaki had acquired in a day was not in the dimension of effort or talent. It was because it was a 'phenomenon itself' that was close to how the world works, so to speak.
　He couldn't realize that the biggest mistake he had made was using his abnormal sister as a reference point - the discrepancies that had continued since his childhood became even wider.

　And the training of that 'demon poison' continues for a day, a week, a month, and finally--

That's enough.

　Uzumi gave up.
　He sat down on the bed in his room and covered his face with his hands to hide the tears that were spilling out.

''No, maybe this was just a bad way for me to teach--''
No, you're not wrong. You were never wrong about anything: ....... It never happened. So, maybe...

　If anyone is wrong, it's me.
　I stopped her when she almost said it was the fault of the talentless Aikawa Kaba (me).

　Uzumi didn't even have the energy to torture himself.
　He just looked into the distance with empty eyes in a feeling of emptiness that was spreading. Staring not at Yangtaki, but at the white wall that was not decorated with anything, he muttered quietly.

''If it's really ....... If I have any magic power ......, even a little bit of it, then .......

　Uzura Wave had yet to taste victory just once.
　She has been overrun by her sister, abandoned by her father, lost the meaning of her birth, and spent her days as a corpse as 'the one that isn't there', and today she experienced deep despair again.

　That vortex wave wishes.
　With a snatched voice as if to squeeze out of his soul.

'Just a little bit of ....... Just a little bit, 'Beyond this, I want hope' .......

　I wished (・・・・・・・).

　A very modest - but awe-inspiring 'future reorganization' for a person to wish for, that their life would work out a little better.

'Wow, I wish too: ....... If there is magic, 'Someday, you'll find hope' ...... and I too .......

　Furthermore, Yotaki would also repeat the same wish.

　At this time, the younger sister was also in deep despair at Uzumi's inability to handle the 'Demon Poison'. Shocked by her brother's expected weakness, she laments that she can't change her own future and wishes even more strongly than he did.

　While the room is filled with 'demonic poison' through training.
　The brother and sister, who continue to be distorted by discrepancies, speak of a craving from their souls.

　--that's what the 'slice' heard.

　With a pakkiri, a dry burst of sound could be heard.
　No one could hear that sound.
　But there was indeed a loud crackling sound.

　It was the moment when the procedure of the "One who steals reason" was carried out, albeit briefly.

　-- it was also the moment when the first real (...) 'magic (...)' was activated, albeit unconsciously.

　Of course, both "magic" is incomplete.
　Even if it's a prototype or template, it's a failed magic at this point in time.

　The same 'magic' used by the future 'The one that steals the reason of the wind' and 'The one that steals the reason of the tree'.
　The older sister is 'rolling down the road', 《The Road Falling Earth (Lord of the Road).
　The younger brother is "Keeping the Place of Return" and "The Lord of the Road (Lost vi Aisia)".
　Both of them had become "trying to get what they wanted and wished for, but missing what they really needed" failed magic.

　The same quality as that sister and brother is now activated in the siblings.
　That failed magic is the reward for the month-long training of the "Demon Poison", and that's the last time the two of them have to stop training.

　What if - what if.
　If they had continued to patiently train here for another year or so, the two of them would never have visited the other world.
　However, the two of them were still young and too 'ideal'. Because of their excessively talented childhood, they couldn't conceive of spending a year on one thing, so they couldn't lead the real 'magic' to completion.

　Thus, the power of that failed magic interferes with reality.
　It appears in the form of "Future Modification" in the story of the brother and sister.

　She was a very straightforward and vivacious girl.

''--Long time no see, sir!

　Her name is Konagi.

　In the form of "Childhood Friends", a different approach to "Family", the siblings will find hope in life together.
　Without knowing anything about it.
