"--My heart is about to break.
　Before that, a 'childhood friend' appeared.

　The girl named Lake Nagi had a positive, cheerful and beautiful personality anyway.
　Above all, she was a strong core. Even though she was in elementary school, she had the strength to stand up for herself, even if the people around her looked at her as a stranger.

　The strength and straightforwardness of heart that did not suit his age was dazzling and warm to his distorted siblings.

　The elder brother Uzunami and his "childhood friend" were in the same grade at the same school and soon became friends. And under the influence of his "childhood friend", Uzunami's dark life gradually began to shine through.
　The black eyes, which had only seen the Aikawa family, finally began to see a different scene and value system.

　They pretended to be strangers in the school due to family reasons, but it wasn't long before they became friends, calling each other to their rooms.

　Smiles began to spill over onto Uzumi as she gained her first friend.
　For example, that was when they were playing a game together after school.
　Unlike with her sister, Uzurinami didn't play the game alone. Lake Nagi had told me that it was better to play a game that I could play with someone else, so I was forced to play competitive games and app games. His choice of games always made him look reluctant, as he liked to play single-player games, but in the end, he nodded with a not-so-full expression, saying, "I can't help it. Sure, relax your mouth.

　Undoubtedly, there was beginning to be a slight hope in Uzumi's life.

　--just one more person who was important here.

　For his younger sister Youtaki, Lake Nagi was a 'childhood friend' as well.
　It was the same for her sister who was beginning to see hope.

　Lake Nagi and Yotaki.
　The two were often evaluated side by side as child actors of the same generation. Their circumstances were very similar, including their family background, and the two of them had seen each other several times at work outside of school. And each time they were approached by the older Kunagi side.

''--Yotaki-san, you're competing with me again today!
...... Hi, senior.

　It was annoying at first.
　To Yotaki, Lake Nagi was not even counted as one of the miscellaneous fish - not even counted as one of the miscellaneous fish.

　At any rate, she wasn't in a 'match' with Lake Nagi.
　Compared to the other talented children, she was far less competent as a performer.

　Most importantly, she lacked desperation.
　No matter how many times she lost, all she could say was, "I'm so frustrated! Yotaki could see that he was not regretting it at all, just repeating it. No matter what happens, Lake Nagi doesn't regret or feel remorse. That's why he would repeat the same defeat over and over again. Rather than not fighting seriously, Yotaki had decided that she wasn't trying to beat me in the first place, and had stopped counting Lake Nagi as a challenger.

　He didn't see the girl called Lake Nagi as 'equal'. However, he noticed that she was always close to Yotaki.
　It was hard to give up, and over and over again, she would say, "It's another day to win! He challenges me with a challenge.
　Regardless of the other party's convenience, no matter how painful and heavy Yotaki's head was, no matter how full of despair, he would deliver that noumenal, loud voice to the back of his brain.

　-- it was a really annoying voice, though.

　My sister was the same as my brother. ''It can't be helped,'' she said reluctantly, but with a face that wasn't uneven, she nodded her head. Indeed, with a loose mouth.

'I don't mind the game, but ....... You can't win anyway, can you?
'You won't know that until you try. Today is the day I'm going to stand out more than you.

　Yotaki already knew the meaning of his own smile, the meaning of his own smile.
　However, it wasn't an 'answer' that he knew from his skills, but an 'answer' that he had obtained with his own strength.
　This girl called Lake Nagi was going to be his first friend, and even his head, which was no longer moving as far as it could go, was able to understand that. So--

　She was a hope for Yotaki's life, too.
　And just as he had foreseen, they would become friends before their secondary schooling began.

　Sometimes, the light of a girl named Lake Nagi would come in where even her family would not step in.
　That was when they finished their usual farcical game.
　Instead of spitting out the standard "It's so frustrating," line, Lake Nagi would utter it with a mysterious face.

' -- I'm sorry for not always being able to deal with you. ...... This won't be too much fun, will it, Yotaki-san?

　It was just the two of us that day.
　It just so happened that they were both working at the same place and the Aikawa family's car was not available. So the older Kunagi suggested, "I'll send Yotaki-san home, since she's close to home," and the two of us walked home side by side.

　Inside the big city in the 'original world' that hadn't yet frozen over.
　Amidst the waves of people, the two girls speak.

'...... No. Thanks to my seniors, I don't float at work and I still feel very safe. It's not like I can't be a partner and have fun--

　Before Yotaki could say absolutely not, Lake Nagi shook her head.

''Because Yotaki-san is always sighing. Very boringly ......, and somewhat painfully.
............

　Yotaki was so surprised by this point that he couldn't continue with his words.
　The surprise was great because he knew that his performance was perfect.

　It wasn't an exaggeration or anything, Yotaki was hiding his troubles with the best performance of mankind through The Demon Poison. There was no way anyone could understand, and in fact, no one had understood it all along.
　And yet, this first friend of his--.

''I know that you have problems that I don't understand, Yotaki-san. And that you can't talk to anyone about it. All the time you have been acting out, not just with me, but even with your parents.

　He was looking over his shoulder.
　Yotaki had no choice but to honestly admit his friend's point.

'...... Maybe so,'

　Since the proliferation of 'massless nerves' began to run amok, I have been doing a 'healthy and energetic Aikawa Yotaki performance' to keep that raw-skinned pain from showing on my face.

'Yotaki-san, please don't make that face,'

　Squeezing tightly, Lake Nagi grabbed Yotaki's hand.
　He pulled back his hand even more, leading it forward and forward.

　Yotaki looked up at her big back and followed her.

''I'm sure we'll meet one day. A 'equal' friend who is 'equal' enough for you to consult ....... No, your friend who surpasses you will definitely be there somewhere one day.
'Over me ......?　I can't be--

　There is no way there is, and Yotaki knows the 'answer'.

　Ever since the day when his older brother's expected results were so shameful, Yotaki has been searching for a solution all by himself. Whenever he found the time, he used every possible means to learn about many different fields and to "see" the countless possibilities of this "world" in the future.

　I have never once seen a being that is greater than me, even in the future.

I don't dislike Mr. Yotaki's personality, which immediately answers that there is no such thing ...... I don't dislike it!　But that's arrogance!　We're still kids, and when we grow up, we'll know that there's an upside!

　Lake Nagi turned around and scolded her junior, giving her a dekopin on her forehead.
　He could have avoided the fakepin if he wanted to, but Yotaki didn't avoid it, he accepted it and listened to his senior's advice.

''Yotaki-san, it's a big world. That's why there are so many different people. As for me, I was really surprised when I found you guys. So you shouldn't give up yet. Just don't give up!　Of course, I haven't given up yet either!　Because there's never a chance that I'll be an actor beyond you one day!

　Not caring that it would be in the city, Lake Nagi declared proudly.

　Youtaki, who was hit with the words riding on his thoughts, moved his head that had been 'still' for a long time and made him think for a bit.

　It seems useless to say that Konagi-senpai hasn't given up.
　I also don't agree that the 'world' is big at all.
　Nor is it possible that there is 'someone' somewhere that exceeds me.

Senior citizen ......
Yes, I'm your senior. This senior, believe it!

　But trust me, Lake Nagi said, pounding his chest.
　Youtaki thought that was irresponsible.

　But certainly, the possibility is not zero.
　The possibility of seeing it with 'future vision' is still about a dozen orders of magnitude.

　I haven't seen beyond Nayuta.
　So, certainly, it's still not zero.

'Besides, you have an older brother, right?　My trusty brother.
My brother is, well, you know: ......
"Uzuraha-kun still seems to have a strong sense of dislike for his sister (you), but ...... it's changing little by little. One day, I will definitely pull that neck and neck and take you out to your front door. When that happens, the three of us will play together.

　Lake Nagi was trying to lead her special friend's problems to a solution in her own way.

　That friendship moved Yotaki's heart.
　Since that day, the thoughts he had been stopping to think about were shaken.
　It's the first time that you can believe in the figure of your senior who never gives up, no matter what the situation is, and continues to do what he or she can do.

''Yes. Thank you, senpai .......
'Yes!　If you want to thank me, you can take this opportunity to call me your sister!
'Huh, I'll refrain from doing that. It's weird.
'Ki, creepy ......!　Well, well, okay. You still have a chance.

　Like sisters, the two of them held hands as they continued on their way home.

　At this time, it was Lake Nagi who supported Yotaki, pulling his hand back and showing him the right path.
　If Lake Nagi hadn't shown up, his brother would have completely broken his heart during his middle school years and his sister during her elementary school years. That's how much she was a hope and a light to both of them -- to the point of feeling doomed, 'childhood friend' was the 'ideal' for the brother and sister.

　--In other words, she was someone who was too convenient (...) for the siblings.

　With the appearance of the convenient "childhood friend", the life of the Aikawa siblings gradually brightened.
　It was, for example, the end of their childhood.
　In an empty classroom at dusk, Uzunami talked with Koonagi and got what he really wanted.

''--Yes. From now on, we'll always be together. ...... I want you to be with me.
'Yes. I won't disappear from Uzumi-kun's presence. ...... From now on, we are 'all together'. So please don't cry anymore: ......

　With the persuasion of Konoagi, Uzumi's mental distortions were completely healed.
　In a chain reaction, the "family" called the Aikawa family also begins to be affected by this. With Uzumi's distortions gone, father and son, who had long since crossed paths with each other, were finally--

"Dad, we're all going to stay together!　I want us all together!　From now on, we'll be together forever and ever!
'Yeah, yeah, ....... That's good for me too. That's what I've always liked about ....... I have a family. Even though I'm such an idiot, Uzumi--if only you were here, that's all I'd need .......

　We understood each other.
　With the words "we're all in this together" as a starting point, the rift between parents and children disappeared.

　It wasn't just about the brother and father.
　The relationship between my sister and my mother also changed.
　Youtaki, who had been doubting his mother's love for him for a long time, is able to talk to her about it.

''--Yotaki, listen to me carefully. All along we have been treating you guys wrong. I and that person didn't know what a normal family was because we didn't ...... know what a normal family was, so we kept making the same mistakes.
Oh, mom, ......?

　Yotaki is confused by his mother's confession, which he has been avoiding for a long time.

'We only have a 'family' called us. That's the only thing I didn't realize ....... I'm really, really sorry. My sweet Yotaki.......

　With that, Yotaki was embraced by his mother.

　Everything (・・・・) and too much is done (・・・・・).
　As we know, all of this convenient development is just the result of fate being distorted by 'magic'.
　And that 'magic' has an end.
　Everything began to fall apart when the brother and sister finally began to get the human-like feeling of 'love'.

''-- Thank you, senpai. ...... I'm starting to be able to talk to my brother, more decently than before. Besides, I'm getting to know my family a little more .......

　Also on the way home.
　The two slightly taller men are walking side by side, just as they once did.

''That's good to hear. Hmph, so how about we thank you this time by calling me your sister?
No, thanks. It's a bit of a problem.
'Mmmm ......!　Why do you hate it so much, calling me your sister, so much?
'Seniors are a thing: ......
'Allee!　What was that thing you were talking about?

　At this time, Yotaki was beginning to feel like Lake Nagi was his real sister.

　Even though she said differently with her mouth, Yotaki knew it.
　In just a little while more, they would be able to have a relationship where they could casually call each other 'Konagi sister (hey)'. The hope that he could see a long way away was almost within reach. This long and dark tunnel has a way out, that's what I thought - and that's when the "magic" was broken.

　The Aikawa siblings got their "special someone".
　The process of getting her was the effect of the "magic".
　So, up to here.

　On that day, Kunagi dies in an accident (・・・・・・・・).
　It's very simple, like a lie, and indifferent.

　The news of her "childhood friend's" death is delivered to the Aikawa family.
　The next day, the funeral has begun.
　The siblings have no choice but to attend the funeral, unable to admit the reality.
　Uzumi was stunned from her position near the coffin. The devastation was so sudden that it was obvious at a glance that her mind hadn't caught up with the reality of the loss.

　However, her sister was a little different.
　She was standing in the back of the crowd of attendees with a grim expression on her face.

　It was because she had been informed of the 'answer' that this wasn't an accidental death with her skills.
　He sensed a gaze (...) from behind him and turned around.

　--The 'slit' was watching intently.

　Furthermore, after this day, deaths due to unnatural accidents began to occur around the siblings.
　Youtaki was the only one who understood the meaning of this.

　This is the 'price'.
　I'm being paid for the "magic" that brings the future of my brother's (...) "ideal" until today.
　In other words, when I trained to use "magic" in the past, I subconsciously made a "contract" with him. Uzumi had obtained enough power at that stage to be worthy of his wish to 'change his own destiny', and he had paid the 'price' of [the death of the one he loved the most].

　Everything is an equivalent exchange.
　If you want to get a 'precious person' from nothing, then the 'price' has to be the death of the 'precious person'.

　-- so this is what happened.

　And this is where the 'magic' of this time is the reason why it is a failure magic. ...... Even though Uzura Wave lost Lake Nagi, it still hadn't paid off [the most beloved person dies].
　It's a good thing that you're able to get the most out of it, because it's incomplete, and Uzuraha's 'magic' didn't even make her a 'precious person' worthy of the 'price'.

　-- so the debt remains.

　That debt will try to collect the next one.

　Clearly, unhappiness was beginning to continue in the Aikawa family.
　A series of scandals were made public, with the father and mother's business failures leading them to commit suicide one by one.
　Immediately, Yotaki worked behind the scenes to keep his brother and parents' hearts away from him so that [the one he loves most dies] would not be satisfied. Even in school life, he turned his hand to prevent any more 'significant others' from leaving.

　As a result, my parents only avoided [death]. They managed to avoid the worst possible outcome in the form of an arrest. But even so, the debt still wouldn't go away.

　-- Even though he lost everything he had obtained, the debt still remained.

　It was then that Yangtaki understood the too unreasonable 'deal of the world'.

''This kind of ......, it's just a 'curse' .......'''

　The first person to utter that name was Yotaki.
　There is no such thing as an equal 'magic' in this world, like in a game.
　When Yotaki realized that there is only a 'curse' - that's what Uzuraha also noticed the abnormality of the surroundings.

　They immediately gathered in Uzurinami's room and decided to have a 'family meeting', although it was only the two of them already.
　In the dark room where even the game lights were gone, Youtaki was questioned by Uzurinami.

''--Hi, Yotaki. Why?　How did this happen: ......?　Lake Nagi, my dad, my mom, and all of this now: ......!　It's not normal!

　Yotaki couldn't answer.
　The reason for this is because he felt that if he told the truth as it was, his brother's spirit wouldn't be able to sustain it.

'That day ......, that day?　I wished for 'magic' in the middle of the day and stopped, so that's what happened ......?　Nah!

　But his brother, alone, was on the verge of arriving at the 'answer' that the cause was the training of 'magic' in the past.
　To his sister's silent affirmation, Uzurinami continued his pursuit.

'Hey, Yotaki ....... Just answer me this one thing. Am I ......, this me, the primary cause of all this?

　Even if he doesn't answer, his brother can get to the 'answer' alone if he has the time. Deciding that there is no point in continuing to be silent anymore, Yotaki opens his mouth.

''Ever since I learned of the ...... concept of 'magic', it seems that my brother has been unconsciously using an incomplete 'magic'. So even now, the 'slice' is still looking at your brother alone, all the time. As if to tell you to pay for the miracle of 'magic': ......
"Well, 'magic' debt ......?
Now, let me explain--

　The reasoning of the world, such as "magic", "compensation" and "curse", is revealed to my brother one by one.
　The truth of the past few years of too much made up life, trembling in his thirsty throat, he 'answered each other'.
　Uzurinami, who received it, smiled with tears in his eyes and let out a snatched voice.

''--Ko, this is ......, even you can't do anything about it, can you?
'I couldn't. ....... Sorry.
'Ha, haha ....... Hahahaha!　So everything since that day was 'magic' ...... and a lie!　The kind dad and mom, the kind dad and mom, that Lake Nagi's words, everything!　I wish it were a mirage, but it's a lie?　Yangtaki!

　Uzurinami shouted mercilessly what Yotaki had been trying to avoid thinking about all along.

　The replacement for the 'family' they had finally found was a 'make-believe'.
　At the truth of this, Uzurinami spilled the tears that had gathered in her eyes.

'It's ...... a difficult place to be. However, surely it wasn't all a lie. It's just that there's a high probability that he was saying and doing things like that as a result of being interfered with and guided by the 'demon poison'--

　While saying it, Yotaki thought it was impossible.

　Certainly, there would have been a child originally named 'Mizuse Lake Nagi'. The family register from birth to death had been confirmed, and the existence itself was real.

　However, there's a high possibility that that abnormal mental (or spiritual) strength was 'magic'.
　Under the influence of Uzumi's 'magic', he had become such a well-formed child, and it makes more sense to think that his fate was being played with so that he was forced to come into contact with the Aikawa family.

''That means it was a lie!　You're talking about playing with her mind and her life!　That can't be allowed to happen--!

　The whole time, Yotaki tried not to think about the truth of it, but Uzurinami would speak for him.
　Unable to deny it, Yotaki shuts down completely.
　However, his brother continues to monologue.

''Such ....... Because of us, Lake Nagi is ....... No, was that really her ...... in the first place?　Didn't the real Lake Nagi have a different personality: ......?

　The power of the Demon Venom is so fierce and so foul that it distorts even the laws of the world.
　If exposed to such a thing, there is no way a normal (just) girl could resist.

　In other words, that joking tone of voice - that unusual core strength - that care and kindness to us siblings, always being so kind to us and Warm, reassuring - and for the first time, a senior who I could truly trust.

"So you're saying that it was me who wished for 'We're all in this together' ......?　That Lake Nagi girl is magically manipulated by ...... and just told by me to do it?　Manipulated for my convenience ...... and played with my mind ......

　That it was all a lie.

'Maybe. ......'

　This means that the hope that she taught me that there was no chance of that happening is also a lie.

　She was only told because her siblings wished that there was "no chance" that there was no chance, she was told.
　That's the 'answer'.
　It's just a 'dream' that if you 'see into the future' to Nayuta's destination, there is still a possibility.
　If we quantify Nayuta's future, it's not just 0.000000000000000000000000. The '1' that is so far away is, in reality, equal to zero.

'So, in the end, ......, did our 'magic' kill you?　I don't think so--

　She died just to show such an unlikely 'dream'.

　When she came to that conclusion, Uzumi was hanging down and covered her face with her hands.
　And then she spilled out some words that were not directed at anyone.

'Why ......, why ......, why not? I don't like it anymore ....... I just wanted a little ......, just a little bit of ......, just a little bit of ....... And yet .......

　There was a glimmer of hope in the air, which made the darkness of despair deeper.
　The spirit (mind) was becoming even more distorted than it had been when it was made into something that didn't exist. The vessel called the soul creaked, cracked and crumbled, and in the end...

"Hey, you-taki ....... How do I go about ......?　I don't even know what to do with me anymore ....... I don't know what to do anymore, nothing ......, I don't even know ......

　--I've reached my limit.

　The broken-hearted Uzurinami heard that, along with unstoppable tears.

　However, that "what should I do?" line was the same for his sister.
　No, it kept reverberating in her head long before her brother.

　The problem of that 'constitution that inhales 'demonic poison'' has not been solved yet.
　The 'conversions' have not stopped, and the 'massless nerves' have always been increasing. Even now, a voice that is my own, but not my own, is still speaking in my head. It keeps giving me "answers" that I don't need. I haven't experienced silence for years, nor have I slept well. No matter how many virtual 'massless brains' you create, they will soon be punctured. I'm starting to get tired of being a machine that keeps moving until it breaks down. I'm sick of it. How could I let this happen? I'm not going to be able to ignore the weakness that I've been hiding for a long time - if only I had normal happiness - if not for the support of Konoagi, I can no longer ignore it.

　-- so Yotaki is also reaching his limit.

　I don't understand the reason anymore, and everywhere I look, it's dark. No matter what I think, I don't know where I am or what I'm doing, because it's not me. And yet, it hurts so much.

　I try not to think about it, but the truth is, it hurts.
　It's pure "ouch, it hurts and it hurts" all the time.

　The screams of painful, painful pain are annoying because I can hear the number of nerves that keep increasing.
　It's one 'answer', so I keep being forced to inform myself. 'I don't want to be in pain.' 'Why do I have to go through this?' I keep hearing, "Help me, please. The same is true of the painful, painful, painful emotions. It's like a virus multiplying, spreading endlessly everywhere, eating away at my soul. It's as if my whole body is being eaten.

My brother ....... Do you remember The Promise, ......?

　Yangtaki asked as he squeezed out.
　With a single hope, he made one last check.

''Ya, 'promise' ......?''
'You can't beat me, my brother said ....... Indeed, I said .......
'Did you say that ......?　I'm in Yotaki?
Yes, sir.

　The reply wasn't what I was expecting.

'I don't remember ....... Forget it. There's no way I can beat you .......

　His brother shook his head and denied it.

　Yotaki knew in advance that the 'answer' would come back to him.
　It was inevitable, he thought. He also thought it was obvious. However, she also believed as a sister that her brother might be able to surpass it.

'Yes, forget it. ...... Just forget it. Everything, everything .......

　Yotaki knew that if he let it go, he would really forget about it.
　Uzumami has a sense of 'contract'.
　For example, if you get the appropriate power and successfully bear the 'price' of 'forgetting', you will be able to escape from this painful truth.

　You-taki alone is responsible for this situation - all you have to do is not to get involved with the 'Demon Poison' or the 'break' ever again. Even if many hardships and misfortunes were waiting for the 'curse', you can live a human-like life and die as a human being.

　That is the best thing left for Uzunami, and that's the ending Uzunami himself is hoping for now.
　But in that enviable end, there is no sister named Yotaki.
　She doesn't even exist.
　Unlike his older brother, who could die easily, his sister's future is--

【--As the 'last person', Aikawa Yotaki continues to go around the 'world'.
　Forever.
　Forever and ever and ever, 'forever' alone--]

　The 'answer' had already been given in Yotaki.
　He had been listening to that scream and weakness for a long time by himself.
　The truth was--.

　I don't want to be alone.
　I'm afraid of being alone.
　I don't want to live all the time, alone.
　But (...) the thing I'm most afraid of is (・・・・・・), alone (...)...

　With that last, Yotaki stopped thinking, completely, (...)

　His mind was broken, he was overcome with fear, and he instinctively stopped thinking.
　Next, Yotaki stopped wishing and hoping.
　Finally, he also stopped believing in something.

　After he finished stopping everything, Yotaki muttered like a cold machine.

''Brother ....... If it's me now, I can not only ...... forget, but I can even freeze the past time and 'never happened'. I have the power to do that .......

　Youtaki doesn't feel anything anymore.
　So this 'answer' is not Yotaki's.
　It's about the future of the siblings, but the 'answers' other than those of the siblings will be given in this 'family meeting'.

''Yes, no ....... You don't have to go that far. I just want to forget about it. I just want to end up here and now. That's all I need to do now: .......
I understand. Okay, I'll just erase the memory.

　Yotaki surrenders to his own skills and lies.
　Uzumi can't see through that performance.
　So, their future together is--.

[-- No, you are not alone.
　The two of them are going on that 'eternal' journey.
　Aikawa Yotaki always had a 'family' next to her that loved her in the true sense of the word.
　At all times, always and forever.
　Because it was the two of them for a long, long time, 'forever'.
　There was nothing more to fear--]

　The end of the story is confirmed.

　Right now, the voices that were bubbling up inside Yangtaki, such as 'You are my brother', 'I will never let you go', 'When it ends, you will be with me', but it would never show on his face.

But for some people, the erasure of memories is as good as death. ...... Brother, are you sure you want to do this?
'No matter. I'd rather be ...... dead than dead.

　Broken-hearted Uzumi had abandoned the idea of living.
　Even if he was willing to become a cripple due to the side effects of losing his memory, Yotaki would not allow that outcome to happen.

''I understand. I'll erase my current brother and make him a different one. After that--''
Just leave me alone. It's all over in this house now. That's why you want us to go to ...... and leave this house alone.
''No, I will definitely erase your brother's 'curse' for losing his memory. ...... I'm sure.

　I repeated twice to 'sign the contract'.
　However, the suggestion seemed surprising to Uzumi, and he confirmed it.

'Will you turn it off ......?'
'That definitely came about because I asked you out. So if I don't turn it off, I'll have a bad aftertaste.
...... Thank you, Yotaki.

　At this time, Uzurinami believed that 'Aikawa Yotaki is healthy and energetic, and there is no 'curse' and he remains strong' due to 'Aikawa Yotaki's performance'. So, he thanked her for going out of her way to help her brother who "taught her so much magic, but instead of understanding anything, he gave birth to the 'curse'".

　My sister smiles and, acting embarrassed, swears in her heart.
　The memories and the 'curse' will be erased.
　Instead, your brother is 'my brother'.
　I'm not going to be able to get the same thing for you.

　Oh.
　It's not just a matter of time before you'll be able to get your hands on a new one.
　Always and forever and ever together.
　I'm not going to be able to say that I'm not going to be able to get it right.

　Along with the thought that, Yotaki approached the whirlpool wave that poked his knees and let out a voice.

''-- 《Stop (...)

　It was his first attempt.
　However, Yotaki knew that it could be done.
　The magic later called 《Freeze》 invaded Vortex Wave's body while lowering the temperature of the room. It also contained the power that would later be called 'Water Reason'.

　The sudden change in temperature caused by the magic caused Uzura Wave to lose strength from his entire body and almost fall down. However, he managed to avoid falling down by grabbing Yotaki's shoulder nearby.
　Yotaki explained his magic while overlaying his hand on the hand that was extended to him.

''It will be a rough job, but I will freeze ...... your memories and make sure you never return.
"Freeze your memory. ......?　Is this the true magic of it: ......
No, brother. This is not magic. There was no such thing as ...... magic in this world as convenient. What we found was ......, just a curse.

　Yotaki doesn't believe in anything anymore.
　That's why he denied the existence of 'magic' like in the game and called it a 'curse'.

　Uzurinami would also agree with that.
　He loved the game more than anyone else, and that's why he didn't want to call this power, which was not at all equal or otherwise didn't make anyone happy, 'magic'.

'Yeah, right. ....... That's right. There was no such convenient thing as magic that could make everyone happy .......

　The vortex waves are giving up and at the same time, their attachment to this world is disappearing.
　The cold air takes away not only his whole body strength but also his consciousness.

　If he meditates on it, his memories up to today will disappear.
　Uzurinami, who believed in Yangtaki's power more than anyone else, was sure of that.

　And he believed his sister's advice as well.
　The disappearance of memories was as good as death.
　So he thought this was his final farewell and left his true feelings behind.

"I am (...), weak (...) ....... So, change ......, wanted ....... All along, you (...) ......, like you (..) ......, like (・・・・) ......, become (..), wanted (..), wanted (..) ...... --

　He said that just as he was about to pass out.
　Yotaki heard his last words and replied to his brother, who slept like he was dead in his arms.

''I can be, brother. Because next time (...), I'll be watching you all the time.

　He did not change his expression at all.
　He just touched his brother's black bangs and stroked his forehead while telling him in a matter-of-fact manner.

''From now on, I will continue to watch next to your brother. No matter what happens, I will never abandon him. No matter what weaknesses you may have, I won't let it end. --I will no longer choose any means.

　That's the best 'answer'.
　Until now, Yotaki had doubts about that 'answer'.

　He resisted getting stronger.
　He wasn't sure if that was really a good idea.
　He tried to cure his constitution.
　So he made a mistake.
　It cost me her.

　From now on, I won't doubt it anymore.
　I'm just going to accept all my powers, and I'm going to obey - without resistance or hesitation.

"If I obey, your brother will be 'equal' to me. ...... Oh, it seemed to me now that it will surely happen ....... Huh, hmmm, haha, hahahaha--

　If I continue on this path, I will surely become a monster.
　And it's not just any monster.
　It's also not just a "monster", it's the "final enemy" in the final battle, just like in the game.

　I really wanted to be the "heroine" who is saved by the "hero (hero)".
　That's why I was clinging desperately to being a person for so long.

　But I realized that I couldn't do it anymore.
　I realized that I couldn't do it.

　So I don't think about it anymore.
　The only thing that comes to mind is.

[-- because it was the two of us for a long, long time, 'forever'.
　There was nothing to fear anymore--]

　Only this ending.
　I only believe in the ending that your brother will be next to you and there will be nothing to fear anymore.

"I don't care about the process anymore ......, I don't care about the process. All I need is that outcome .......

　That way, you won't be afraid.
　You can skip to the ending of [two people in "forever"] (・・・・).
　I know that I can skip this hard time and find myself at the end of it - and I know that I'm going to get to the end of it.

　Yes, I know. From the beginning, I knew how it was going to end. I had the best 'answer'. So, fine. I know, and it's okay.

'Brother, I'll rebuild it for you now: ....... I'll rebuild it for you: .......

　Thus, Yotaki, whose heart was broken, accepted the 'massless nerve' that he had always neglected.

　He manipulated it as his own power, stretched it out like a white 'thread' and let it out of his body.
　Instantly, he was hit with a pain that felt as if sulfuric acid had been showered on his pain sensation itself, but Yotaki gritted his teeth and endured it through.

''Fu, fufu--!

　As a matter of fact, quite some time ago, Yotaki was able to manipulate the 'Massless Nerve' outside of his body.
　However, he thought that if he had to endure that pain, he would cease to be a person, so he had been stepping away for a long time.

　However, the fetters were finally removed and Yotaki stepped in.

''I'll change it now, by my hand, so that you can be 'equal' ...... with me. ''My brother.'' ......

　He takes his own 'massless nerve' out of his fingertips and invades his brother's head and connects it.
　Then, he reads everything about his brother.
　First, Yangtaki tasted the 'Demonic Poison' inside his brother's body as he rolled it on his tongue. He laid bare all the information that could be said to be his constitution and nature, including the shape of his soul vessel.

　It was at this time that Yotaki learned that his brother had a "constitution that reflects other people's 'ideals'".

　It's a foul talent.
　But it's not enough.
　It's still not enough to get him to be 'equal' with me - to play with him.

'He's 'my brother'. We are a 'family' of 'equals' who can forgive each other for anything. We're ...... and we don't condone it.

　First, erase the memories.
　Using the power of Stillness, he completely excluded his parents and childhood friends from Vortex Wave's life.
　Then, I added another memory to the excluded part. In order to become Yangtaki's 'ideal brother', he implanted the memories of the closest siblings in the world, like the ones in the game.

　With more than enough 'Demon Poison' and 'Massless Nerves', it was possible.
　However, as he worked on it, the 'massless nerves' grew one by one from each of Yotaki's hair, turning into white 'threads' that grew one by one.
　It didn't take much time to fill the floor of the room.
　Countless white threads wriggled and danced in the air, wrapping the vortex wave's body like a cocoon.

　And within that cocoon, Yotaki experimented.
　She decides to do it for real, and she doesn't hesitate to use her brother as a test animal (guinea pig).
　She knows it's the shortest and best way to do it, so she tries it out unhindered.

　How will the vessel of her soul change as she repaints her personality?
　How does the 'break' work if you let the 'contract' compose what kind of 'contract'?
　Which 'curse' do I get and what kind of power does it give me?

　Because he was serious, he was able to resolve questions that would never be answered without a laboratory animal (guinea pig).
　In parallel, my brother approached the vessel of the 'ideal'.

　It was remade many times until it was comparable to Yangtaki's predisposition.
　Memories and personalities were added and subtracted until they hit a strong constitution and nature.
　Believing only in that last page, over and over and over and over again--

　This is the beginning of the two 'Gentiles' as 'we' know them.
　It's the beginning of 'The One Who Steals the Reason of Water' Hitaki and 'The One Who Steals the Reason of Dimension' Kanami.
