It's not just magic power that gets intertwined.
　Consciousness is also intertwined, dissolving and blending together.
　It was a terrifying sensation as if my soul was being stripped from my body, but for me, it was the third time.

　What awaits us after the "Prequel (Recall)" (Dimension Graduate) has reached its peak.
　It's just a space where there is nothing but consciousness.

　Not long ago, I remember calling this place the 'Inter-dimensional Space' and 'Inter-lineage'.
　I will use my previous experience to keep my ego in check and reaffirm what I am to see from now on. This is a place that has escaped not only the concept of time, but also the logic of the world.
　There is nothing that cannot be seen.

　--From now on, I'm going to read the story of the Aikawa siblings before they wandered into another world.

　When you read it, it's the story of the end of everything.
　If it were a book, it would be the final chapter. No, the last volume. It's a book where there's no more to follow, where the ending can't be helped no matter how unsatisfying it is, and where you're forced to just accept it.

'--hahaha,'

　I laughed in a space where my voice was not supposed to be heard.
　The way I thought started to resemble Tiara - or rather, Las Tiara, and the way I laughed started to resemble Ragne. I was dismayed at how easily I was influenced by others, but along with the will I inherited from everyone else, "That's me too," I moved forward, regardless of whether it was in a space with no concept of distance.
　With a sense of what is waiting for me in the future, I move forward, forward, forward...

　I don't really know the truth anymore, even if I don't hear it or read it, but I'm aware of the faint truth.
　Once I died, I read bits and pieces of it.
　Within the Winter's Otherworld (Wintry Dimension), Tiara read me the story that followed.

　Still, I decided to read them in order.
　Why did I have the "curse"?
　It's not the 'unrequited love' that Yotaki has, but the real 'unrequited love'.
　In order to read them one by one in order, I try to reach out towards the 'past'.

''--Hihihi.''

　Before he could do so, he heard the laughter of a girl who wanted to read that book more than anyone else.

　There was no way she couldn't come out.
　A soul, more accustomed to this afterlife like space than I am, came forward to be that last 'reading' reader.

　And before I can hear a response, Tiara begins to read. Like a child who can't stand it anymore, innocently, joyfully, she takes the book in her hands - no, there is no Tiara's body here, and there is no book made of paper. It's not a space where such an understandable substance can be found. But, indeed, now Tiara, at the end of her long, long 'adventure', has obtained her reward and has begun to read it.

　That book is the beginning of our siblings, and for her, the softest part of her heart.
　Tiara mercilessly reads out the part of the human heart that everyone hides, the 'darkest part of the human heart'.

'Err... ......?　Heehee. Once upon a time, there was a brother and sister who were very, very unhappy with each other--

　It reads like a joke, but I guess it's her way of showing affection.
　I'm not going to stop Tiara anymore.

　Above all, after this long - really long - battle, I was tired.
　I didn't even have the strength left to argue with anyone anymore, so I slowly took a distance and sat down a little farther away. Then I clenched my left hand tightly. Of course, this wasn't exactly accurate either.
　In this particular place, everything is so uncertain, so metaphorical, so vague.
　Without the concept of distance, there would be no place to sit, no hand to hold. But certainly, I thought I was holding "her" hand here.

　I held the "her" book, which was not supposed to be there, to my heart, and just listened attentively and listened.

　The tiara doesn't even pay attention to me anymore.
　I was absorbed in reading.
　Reading a book in a place like this.

　She's just like me. Probably, but he's worse than me.
　He abandoned his master (Kanami), he abandoned himself (Rustyala), he abandoned the world (everything), and he can only see Aikawa Yotaki anymore. The scary thing is that he decided to do so, not by 'curse' but by his own will.

''This is fine ......, Rustyala. Now we're already ......--

　Tiara uncovers (read) Yotaki's mind.
　Me and 'her' hold hands and listen to it.

　This is the end of the story.
　We have finally arrived at the end of the story.
　The end of the other world's exile tale coincides with the beginning of a story about a brother and sister.

　Starting from the first page, from the childhood, in that order.
　This time, I hope that we can all feel the same way about 'All Together'...


　◆◆◆◆◆


"-- 'Born Different (・・・・・・・・)'.

　It was always the starting point of the story.
　So the story of this brother and sister also starts from 'born with a difference'.
　However, in this world, the master - ah, the 'Aikawa Uzumi' who arrived in the other world, called it 'Inborn Skill (・・・・・)', so you need to be a little careful.

　It literally refers to a power (thing) that is different from others from the time one is born.
　That 'innate difference' was all that made up the Youtaki sister - the anomaly called 'Aikawa Youtaki'.

　In other words, "When did that Yotaki start being so strong? If you ask me, the 'answer' is that it is from birth.

　It is a terribly simple, unreasonable disparity without reason.
　Only one 'lord of another world' had a reason for the incomprehensible metaphor, "the fear of the 'world' itself", without any evidence: .......

　-- without a doubt, 'innate differences' was the beginning of the girl named Aikawa Yotaki.

　She was truly blessed by birth.
　Not only was her talent, but her natural environment was extraordinary.
　She was born into one of the world's top wealthy families, and her parents were world-renowned figures.
　Even if this environment did not have much of an impact on the girl named Yotaki, there was no doubt that her family was the envy of everyone. Their residences were located in several of Tokyo's most prominent high-rise buildings, all of which had a car stationed at the house to transport them to and from work, promising a life free of the troubles of having trouble with things.

　However, what is important now is that Yotaki was born with an unusually fast-growing ego, and his parents had given him a private room at his request.
　This was the only thing that mattered.

　When she hadn't even received a primary education yet, she was given a space all to herself.
　And she easily arrived at it.

　At that time, she didn't have a single thinking skill such as 'parallel thinking' yet, but with her innate intelligence alone, Yotaki was able to figure out that she herself had a constitution that sucked 'demon poison'.
　At that time, Yotaki didn't know the name 'Demon Poison', so she called it 'unknown substance' or 'my own personal haze' - but anyway, she noticed 'it (...)'.

　It didn't take her more than a few minutes to train and become able to clearly recognize the 'Demon Poison' with her eyes.
　It only took a few tens of minutes to interfere with and control the 'Demon Poison'.
　It took a day to successfully convert it and absorb it into his own body.

　After leaving the hands of his overprotective and greedy parents, Yotaki became convinced in just one day that he was special, not because he was born into the Aikawa family, but because of who he was.
　And then she rejoices and laughs to the fullest by herself.

'-- I knew this haze was all 'mine'!　Hmph, hmph!

　A haze that had always seemed ghostly since birth, but no one believed in it.
　Knowing the true meaning of it, the young girl, who was a single digit in age, was so excited that she let out an age-appropriate laugh.

　There was still not much stuff in the private room she had just been given.
　There were only minimal educational toys and furniture, but it was already a great playroom for her.

　She played and played and played and played all by herself, using the 'Demon Poison' that drifted around like a fog in the room.
　And as soon as the 'Demon Poison' in the room faded, she immediately climbed onto the bed by the window with her eyes shining.

'Bam!'

　I unlocked the double lock and, with a shout, opened the window with great vigor.
　Immediately a cold wind blows in. Her hair was snatched away and she closes her eyes for a moment. However, the next time she opened her eyes, her vision was filled with 'demonic poison'.
　The empty room is refilled with new 'Demon Poison'.

''Hmph, hmph!　Haha, hahaha--!

　There's more.
　There is still more to play with.

　The reason for this is spreading out of the window.
　The Aikawa family lives near the top of a high-rise building that resembles a tower. Leaning up from that window, Yotaki reaffirms the scenery outside - the 'world' he was born into.

''Wow. ......!''

　The time was night.
　Stardust was glowing.
　Not just above, but below.

　Countless electric lights twinkled on the cluster of skyscrapers that lined the sky.
　The artificial light in the city made the natural starry sky completely invisible. But instead, I felt as if I was floating in a sea of stars.

　Most of all, Yotaki was moved by the fact that there was an unplayable amount of 'demonic poison' floating around in the 'world'.

''This is 'my world' .......

　Of course, it's not as if it's as dense as the 'other world' she'll reach after these years.
　The amount is not enough to make the world sick, but enough to allow it to circulate normally. It's a small category compared to the many "worlds" she will know from now on.

　-- but a monopoly has been created.

　Because there was no competition, all the 'demonic poisons' were Yotaki's.
　And she had the capacity to absorb that one world's worth of them.

　--This is how Youdaki was promised to walk the "most special life in this world".

　Blessed with good fortune, Yotaki was able to get anything she wished for.
　Thanks to the house he was born into, he never had to worry about money. Moreover, she was not bothered by even intangible talents that money couldn't get.

　Even rare talents such as athletics, studies, and acting were obtained by converting the 'Demonic Poison'. In other words, while the whole world was stuck at level one, only one person was able to level up endlessly. Indeed, everything in this world was supposed to be her freedom - but there was one thing that was inconvenient.

　That was her playmates.
　Although within the narrow scope of pre-school childhood, Yotaki was chronically lacking in 'equal' partners.
　Even if the opponent was a child with the world's greatest talent, if he got a little serious and used the 'Demon Poison', he could win. Against another genius of the same age, youtaki was winning and winning and winning and winning, and as he continued to win, he had no one to compete against.

　Yotaki lightly regretted that he had devoured the experience of winning with lust.
　However, she doesn't regret it.
　This level of inconvenience was something she could have predicted in advance.

　Therefore, Yotaki was cautious, not in a hurry.
　If she could tell someone about the existence of the 'Demon Poison', this inconvenience would be easily resolved. But she was not foolish enough to let go of her own advantage. She knew that it was wisest to monopolize it on her own rather than to hide it or share it.
　With the morals of today's world, it's unlikely, but in some cases, there's even the risk of becoming a test subject (guinea pig). Taking the risk of turning the world into an enemy (risk) is a fool's errand.

　That's what Yotaki thought, and she never left the human category - but within the human category, she continued to play the best girl she could think of.
　That's the smartest, funniest, happiest life you can have. In fact, as a child, Yotaki was so happy and joyful in life that she really enjoyed it.

　But there's no one to share that excitement with for a long time.
　Even though he knew it was that kind of 'compensatory' power, his dissatisfaction with the inconvenience slowly built up.

　Yotaki at this time is still a small child.
　His height was only around the waist of an adult. Because he was just a child, he was still able to feel the emotion of loneliness (...).

　So, first of all, Yotaki turned to his family.
　Yotaki's mother was a world-renowned actress and was regarded by the public as a "very family-oriented, personable, and admired Japanese woman".
　However, at this point in time, her "supposedly family-oriented mother" had abandoned her understanding and education of her own child, Youtaki. Naturally, Yotaki was far too good as a child. He was smarter, stronger, more beautiful and more complete than anyone else's child.

　Her mother had sensed from her years of acting experience that her own child was unusual, and even thought it was "weird". But she never lets it show on her face. Even if she was unaware of this abnormality, she was strong enough to make the most of the 'well-built daughter' named Yotaki.

　Even at a young age, Yotaki was able to read her mother's essence at a glance with her innate 'observational eye'.

　He also learned that his father was the same kind of person.
　The adults in the Aikawa family, without exception, were selfish. They looked at others as tools, and would not hesitate to sacrifice them if necessary. It is the same between husband and wife; they are married to take advantage of each other.

　The Aikawa family was a bit different from the average family.
　They were sophisticated enough to survive in a particular industry and were completely useless in terms of distracting the loneliness of their parents.
　And they're not the kind of people you can talk to about 'demonic poison'.

　At the point when there is an 'equal' partner that can be used by each other, these parents are different (...) from themselves - different.
　That's what Yotaki decided.

　On the contrary, he even doubted that he was really their child.
　Both of them were unfaithful, so it wasn't impossible. The more he learned, the more the 'blood connection' that was supposed to exist between him and his parents became less and less, and the young Youtaki's sense of alienation swelled.
　In proportion, Youtaki's ability related to 'demon poison' also becomes stronger - the growth of that 'innate difference' enters the second stage.

''--Huh?　What's this: ......

　In the air, where there should be nothing, something like a 'slit' could be seen.
　I analyzed it as something like the air vents of the 'Demon Poison' - and

'Oh, God, ......, I knew I was--'

　At this point, Yotaki had realized a lot of things.

　Obviously, he was different from everyone else.
　It's not just that what I see is different.
　My nature as a living being is too different. When you are able to interfere with matter that is not perceived, you can no longer say that the world you live in is different.

　We instinctively sense this, and little by little a black curtain falls over the faces of others.
　My interest in others wanes, and a huge gap begins to form between myself and others.

　--this was Aikawa Yotaki's childhood.

　After that happiest period, Youtaki's seventh birthday comes around.
　And finally, the story begins to move in a big way.
　It all started with a single look.

　It happened when Yotaki, who was slowly starting to feel uneasy, was going about his usual life, walking out of the private room he was given and walking down the dust-free hallway of his house.

　The gaze of the 'break' that had been looking only at him all along was diverted.
　Yotaki was caught by the movement of that gaze and turned his eyes to the same place.
　There--.

"-- I'm going to be the 'best' ....... Otherwise, what happens to everyone who comes in to kick off?　The math doesn't add up ....... If I'm not the 'best', the math goes wrong ......!

　There was Aikawa Uzumi as a child.
　He was walking down the corridor, muttering mumbling complaints about who he was angry with.

　Yotaki and his older brother, who was three years apart in age, were children who were instantly recognizable as distorted.
　His black hair was neatly cropped and his appearance was well-groomed. However, he was hopelessly blind. He would talk endlessly to himself and sometimes lose focus.

　There were two main reasons for this.
　The first was the Aikawa family's unique and excessive education for gifted children.
　Then there was the indoctrination of values by his parents.
　This was too much to deprive the child of everything but ambition.

　As a result, Uzunami, a child, had everything in life to do with beating others. Despite this, he was constantly tormented with a sense of defeat because of the unusual comparison of Yotaki, who was placed close to him.

　Looking at his distorted brother, Yotaki thought, "Oh, come to think of it, I had a brother and sister.

　To Yotaki, that was the extent of Uzura Wave's value to him.
　It's just that he doesn't think of them as talentless mere mortals. Rather, thanks to his bloodline, he appreciated that his 'innate differences' were moderate. Most importantly, the surrounding environment is good. He was one of the few prodigies in the country who had been able to take in the gifted education of the Aikawa family alone.

　But he's not my opponent.

''--!　What, you're looking at ......!

　The older brother, who had become a bundle of inferiority complexes, noticed that his sister was looking at him, and he reacted excessively.

　To Yotaki, it was a familiar reaction.
　Children of his generation, once beaten, would be frightened in this way.

　It seemed that his older brother was no different.
　So, Yotaki wondered, "Why is the 'cut-off' looking at this kind of thing--

Hey, you'll see. ......!　Even I'm here (...) ......!　I'm here (・・・・・・・)!

　But he quickly reminded himself.
　Uzuraha didn't want to be 'the one that isn't there', so she bared her wariness in a frightened manner and shouted that.
　Without any preliminaries, he suddenly became combative and declared war.

'Not you ......!　It's me!　This me is the 'best' ......!

　No matter how precocious he was, his roots were a heartfelt cry that could be recognized as a child.

　That declaration of war startled Yotaki from the bottom of his heart.
　The existence on the other side of the 'slice' was the same.

''You're ......, the 'best'?　Why?

　And with that cruel question, Yotaki genuinely harbored it and asked his brother.

''Why? ......, it's .......''

　Uzumi had to stammer.
　He himself is keenly aware of the fact that he's not the 'best', more than anyone else. After all, because of his sister, he's been losing ever since he can remember.
　So the young Uzunami at this time was supported by the 'blood connection' in his heart.

''Bo, I'm 'your brother'!　That's why I'm better than you: ....... Ah!　My brother has to be on top, that's weird!　So--!

　Uzunami believed in the childish theory that he was his brother.

　That would be ignorance and recklessness on account of being a child.
　His bravery was only an illusion, and the brilliance of his soul was distorted.

　Only, in his brother, Yotaki felt a light.
　There was no black tent (curtain) hanging over that desperate face.

''--That's why (...), only you (・・・・・・・), I will never lose (・・・・・・・) to you (・・・・・・・).''

　Again, Uzurinami declared emphatically.
　And Yotaki responded to it - faster than that, the 'break' reacted.

''Eh--?''

　Suddenly, the 'cut' presented the 'Demonic Poison' to the vortex wave.

　Yangtaki's surprise grew even more.
　It is not a good idea to be a good friend, but it is a good idea to be a good friend. Quickly, Yotaki tried to get back the 'Demon Poison' that was given to her brother, but it was not possible.

　For the first time, it was the moment when his brother Uzuraha defeated his sister Youtaki.
　Youtaki, whose record of consecutive victories was unexpectedly stopped, was severely confused in his head.

　Ah, le......?　Losing?
　It's also this 'my own personal haze' that I've been working on ......?

　The shock of defeat was stronger than the shock of being surprised that there was a means of interference of the 'demonic poison' that he didn't know existed.

　His brother, whom he had taken lightly, had surpassed him in a way he didn't even know existed.
　It was also in the field of 'Demon Poison', which was his strongest area of expertise.

　For some reason, that made Yotaki strangely ...... happy for him.
　She couldn't shake the loneliness she felt from being disappointed in her parents, but she was simply happy to hear it back.

''I, are you unbeatable ......?''
'I'll never lose!　Someday, I'll beat you for sure!

　As if to support that declaration, 'demon poison' flowed in from the 'break'. The "Demon Poison" in this place was controlled by the vortex wave, although unconsciously.
　Including the final confirmation of its mechanism, the sister asks her brother.

''Um, say it out loud again ....... Let's see, can you make a 'promise' ......, please?
'Don't make me say it again!　I am your brother and you are my sister!　That's why I will never let you win!　Yes, I've been telling you that for a while now!

　It's my brother, so I won't lose.
　That's what Uzumi vowed, and then Kariuchi supported him with his "magic poison".

　The method is completely different from Yotaki's, but it is true that his brother was also manipulating the "demon poison".
　Youtaki's cheeks loosened at this situation.

''Hmph, hmph, hmph--''

　At this time, Yotaki felt a 'blood connection' for the first time in his life.
　And I was also relieved.

'I won't lose, ......, either. I will never lose to 'brother'--!

　''Even so, I won't lose to my brother.
　With this vow, Yotaki succeeds in extracting the Devil's Poison from the slice.

　With his brother as a role model, Yotaki understands the mechanism of the technology later known as the "contract".
　By swearing an oath to the other side of this "slice" with all your might from the bottom of your heart, a rule is added to the world. By observing it, the world will favor the Demon Poison in return.

　Youtaki's talent for handling the "Devil's Poison" was further developed thanks to his brother.
　That fact made Yangtaki happy, and he put on his best ever smile.

''You're on top of things again, you're ......!　d*mn it!

　However, Uzurinami felt the smile was a mockery.
　After stepping on the ground and hitting the wall of the corridor with an eight-pounder, he left to escape.

　Yotaki looked away from his back and bit down on his first emotion.

''Brother'' ....... I had a 'big brother' .......

　He verbalizes that he is Uzura Wave's sister, and confirms with the 'break'

　--This is the beginning of the brother and sisterhood.

　Not by birth, but by 'contract', Yotaki made Uzurinami his older brother.

　However, the only person who understood the "contract" was the younger sister, Yotaki.
　It's a good idea to be able to have a good time with them.
　It's just a selling word. It's not just a matter of time before you'll be able to get a good deal more than you think.

　--So, it's going to be off.

　From now on, the elder brother Uzunami will seriously challenge his younger sister Youtaki.
　But that's an effort within the realm of realistic 'humans'.

　Youtaki will try to respond to his brother's seriousness.
　However, it is an unrealistic effort to make use of the unrealistic "demon poison".

　It was an irreparable discrepancy (misalignment).
