The setting of Fania's story of saving the "The One Who Stole the Reason of Fire" from Romis Neysha is what would be called a "frontier" a thousand years later. This continent had been given an official name, but it was lost forever due to the massacre of the Otherworldly Hurricane Katrina.

　On the day of the Otherworldly Hurricane, many things really disappeared from the world.
　For example, the calendar. Because I counted the years from the year when the Gentiles were summoned as the "New Calendar", no one can remember the names of the old calendars anymore.

　This I did not let them leave.
　The falsification of history was the prerogative of those who were the last to do so.

　In other words, the true history of the continent could only be followed by special magic or skills anymore.

"New Year Zero (・・・・).
"Summoned to another world, Uzurinami traveled with Tiara, Princess of the Fuzzyards, to Fania in the northeast. There, he met Tida, the 'Stealer of Darkness', and the three of them worked together to sneak into the research institute where they captured Arti, the 'Stealer of Fire's Reason'.
　On the way there, Tida betrayed him, but Uzumi successfully defeated the lord of Lomis Neesha, who was waiting for them, and fully awakened the power of the dimension.
　The sacrificed Arti was saved, the twisted city was corrected, and Uzunami took his first steps as a savior. However, on their way back to their adventure, Uzunami and the others are struck by the bitterness of those who were killed in battle.
　The survivors of the blood experiment conducted by Fania's research institute stand in front of Uzunami. One of them was a boy who would later be called 'the one who steals the truth of blood'. Nevertheless, the two of them joined forces and overcame the boy's 'ordeal' -

　At the end of that journey, I was stabbed to death by a survivor of a blood experiment.
　Furthermore, due to my master's 'curse', I also had to fight many monsters and demons in a serious condition.

　However, as we know since I'm speaking here like this, I didn't die from that level of injury.

　The reason for this is that "I, who was determined to definitely survive no matter what the cost," lightly outweighed "the gentle world that patiently waits for the one who will sacrifice.

　-- As a result, my master and I managed to successfully return home, fending off the monsters that were chasing us and persuading the artificial demons that stood in our way.

　When we reached Fuzzyaz's castle, Master first ordered me to stay still and rest, and then he moved to find Apostle Diprakra to cure him.

　After seeing his back off, I walked off by myself with a bitter smile on my face.
　Ignoring the gaze of the 'slit' behind me, along with the smell of death entangled in my body, I follow the 'thread' that stretches from my fingertips and slowly make my way to the waiting man's place.

　From this point forward, it's a scene that would never be seen in the 'past vision' of a master alone.
　However, if he is connected to me now, he can see it.

　I walk through the streets of my hometown of Huzzya's and enter the garden of the castle while suppressing my aching abdomen.
　As I walked to the place where we always practiced our 'spellcasting' and 'body arts', I found a girl sitting with her back against a tree.

　Sister Yotaki turned her face down and was combing her long black hair.
　When I saw her before, her hair was as long as her waist. ...... Now, the example 'thread' was growing endlessly from the ends of her hair. I'm sure you'll find that the hair that has grown out of it is spread out across the garden like a lake, swirling around like a stream of water. Perhaps it was because of its white color, I thought it looked like something I'd read in a book about the snowfields of Hokuriku.

'-that's what it's like, isn't it?

　Observe the source of the 'thread' and analyze the mechanism.
　When the words of my impressions echoed in the white garden, sister Youtaki looked up and was surprised.

''...... tiara?''

　I thought you would have expected me to be here, but ...... says that's not the case.

　The fact that this is the case gives me hope.
　I'm sure you'll be able to see the surprise on my sister's face as well as the fact that she was able to escape the cutoff and survive.

　Even if it's your sister, it's not an absolute. So now that I'm back alive, I can say the words I've wanted to say all along.

'Yes, it's me. I'm home ....... I did everything you told me to do.

　Sister Yotaki rolled her eyes and muttered, leaving my greeting unattended.

'Why ......?　You certainly like your brother and ....... The 'contract' and the 'price' and already--
Do you like it?　Hehehe, what are you talking about?

　He asked me why, and I would speak my answer honestly.
　I felt like I was showing him how well I had done the homework he had given me.

'To me, a master is only a mentor, you know. I like him as a mentor, but have I ever thought of him as a 'lover'?

　I denied my role towards both the Yangtaki sister and 'cut'.
　I dared to speak bluntly, using 'lover', which had been replaced by another word through translation magic.

''Sure, I like my master, but ....... I'll be honestly beaten by sister Yotaki's brazenness. It's a good thing that we're brother and sister, but we're both in love with each other to the point where we can't be normal. You are more like a 'lover' to me.

　With my words and actions, sister Yotaki seems to have realized everything. She immediately makes a smile and chatters along with me.

''--Hmmm. Isn't it?　I suppose that's normal for a relationship the size of mine and your brother's.
Are you two normal?　Heehee, I'm telling you, you are in love with him. Probably anyone anywhere would say the same thing about me. ...... Wherever you are (・・・・・・・・・).

　I repeat the words and tell the 'break' behind me.
　I'm going to insist that the black-haired girl there is the one who deserves to be the 'compensation'.

'Come on, ....... That would depend on the family. Perhaps Tiara thinks so because her family is unique. ...... More importantly, how was Fania's journey?　I wouldn't say it was a honeymoon, but I think it was as fun as a date, right?　After all, it was the 'adventure' you wanted.

　Sister Yotaki let go of the hand that was playing with her hair and turned to face me.
　As she moved, a large amount of white 'threads' came up from her feet, twisted around my entire body and began to stroke me.

''Adventures'' are very different from what you read in books and what you actually do. You get attacked by bandits along the way, the food isn't as good, and there's no safe place to sleep ...... It really sucked!　Plus, Fania has a creepy religion going on, and they're even experimenting on people, and the experimenters stabbed them in the stomach!　Scattered and scattered, I wish I hadn't gone!

　I activated the skill 'Reading' and put power into my nerves inside my body.

　Even if Yotaki sister's 'thread' entered, I made up my mind not to let it control me.
　I will never again say "I love Aikawa Uzumi" when pulled by the "thread". On the contrary, he would stand around to make them say it.

'Oh, tiara ....... You really are ......--

　Neither me nor sister Youtaki stepped back from each other.

　Comparing the two of us, I could clearly see that the 'slice' behind us was baffled.
　I felt the bill for "compensation" loosen up somewhat, although not to the extent that it was 50-50 with Youtaki's sister - but I felt the bill for "compensation" loosen up somewhat.

　It's really simple.
　I've felt this journey up to this point, but to be honest, the world (that) is easy to control.
　It's better to leave this sweetie alone.
　More importantly, right now, it's the Yotaki sister in front of me.

''You are correct (・・・・). You have a good understanding of how the world deals with each other. Basically, the world sees and hears and judges the 'price'. It doesn't have the power to read people's minds like we do, you see. That's why naming and chanting is oh so important. ...... You really are a wise and pretty girl. Tiara.

　My whole body lit up hotly when I heard the word "correct" from my sister Yotaki, who I admire so much.
　When she complimented me on my homework performance, my face was red with joy and excitement.

　My sister Yotaki, who was looking at me now, had a very serious expression on her face. I thought there was even a hint of respect mixed in there. It's a different expression than the one that said 'incorrectly' before I left for Fania.

　With my personal emotions never ceasing to be felt, I finally took the first step towards the dazzling 'Gentile'.

'This one by my sister Yotaki ....... It's not that absolute, is it?

　I look at the 'thread' attached to my fingertips and speak.
　When I first saw it, I was terrified by the unbreakable "thread", but now I can calmly analyze it.

　This "thread" is creating a "connection" between me and my sister Yotaki.
　However, there is a high probability that Yotaki's sister is choosing and discarding what she can get from that "connection". If you dig up your memory, you'll find that during the training before Fania's departure, she herself said, "It's not me that you're thinking about, it's the skill.

'Yes, just like your brother's 'dimensional power'. ...... Basically, every power depends on the person using it. I can make a 'connection' with the other person with the 'thread' and guide them to some extent, but ...... this time I decided halfway through that Tiara was definitely dead and allocated that ability elsewhere. You've passed through that gap with flying colors, and you've made it this far.

　It would be a failure similar to the master's loss of his carriage on the road while possessing 'dimensional power'.
　As the answer to the question, "What's the best way to go about this?", I--.

'To be clear, I cannot yet say that I am in complete control of this 'thread'. It takes a lot of preparation and planning to guide it, and it can still run out of control, just like the other 'reason stealers' were born with," he said. Although ...... is the first time Tiara has gone through my 'threads' so successfully, though.
Heh-heh-heh. I see, I'm the first.

　Inevitably, my cheeks would loosen up.

　I was happy to be approached, praised and recognized by the people I admired.
　Seeing my condition, Sister Yotaki asked, a little dumbfounded.

''You look really happy, Tiara. You were pushed back by me and almost killed by me, right?　Don't you have something else to say?　More resentment and all that: ......
''That's not true. ...... I love not only my master, but also my sister Yotaki.
...... trying to kill me too?
"Because everything now is because of Sister Yotaki, right?　The state of this world, the actions of the apostles, that master's coolness, everything!　A story written by my sister Yotaki!

　It's so common in books that you almost die in the middle of an adventure. I can only say that because I survived, but I can say that it was one of my favorite developments.

　Seeing my sudden excitement, Yotaki sister's dismay deepened further.

''If it's Tiara now, you can already tell, right?　I'm sure I've written and guided my way in Fania, in my own way. But not everything is the way I wanted it to be.

　Sister Yangtaki shook her head and denied it.

　But that's humility.
　As a book lover, I want you to understand more about how inspiring it is for me to be able to "write my way through" in this real world.

　In order to convey that feeling, I approach my sister Yotaki with my arms outstretched.

''But!　Look at that development.　If it was Sister Yotaki who wrote that battle!　For that alone, I'm a huge fan of Sister Yotaki!　Sister Yotaki is a big, big fan of mine!　

　I stepped around the garden where the white 'threads' were laid out and I embraced them.
　I dare to increase the 'connection' of the 'thread' as well, to convey the feelings I have within me. However, even after receiving that ball-shattering confession, Yotaki's sister narrowed her eyes and doubted.

''...... Tiara, is it true?''

　It seems that Yotaki's sister is not used to being liked, and she is truly doubtful.

It is true. This is not a deception. I love my sister You-taki. You can't get rid of it. I want to have a lot of conversations with her. I want to make a lot of memories. I want to be next to you forever, and hopefully one day--

　I hug her even tighter, saying that I'm not saying this as a ploy.

　I am sure that the more I match my body with Sister Yotaki, the more I will destroy myself. The closer our minds get to each other, the more tainted we will become. I know that. Even so, I wanted to taste the person called Yotaki sister with all my might.

''-- I want to be 'equal'.

　And finally I revealed my biggest goal.
　It was the confession of a lifetime, but then again I am shaking my head.

'...... It's impossible. You have seen the way the world works from the edges of your conversations with me, and you have grown to use my advice and learned to mimic my power, even as you imitate me. That is truly brilliant. But unfortunately, you will surely die of the 'curse' one day. At any rate, the 'Tiara Hoozeyers' have made a 'contract'. The last page leading up to you has already been decided.
''If it's ...... then. If I didn't die until the last page, and I was standing in front of Sister Yangtaki properly, would you admit that I'm 'equal' then?

　The last page was not the "Tiara Fooziers dying in Master's arms" prepared for me.
　I pointed to the last page prepared for my sister Yangtaki and told her that she would definitely survive to that point.

　When she heard that, she sighed with her eyes as she looked at her helpless sister.

'...... haha. Fair enough. If you can shake off all my 'strings' and follow me to the end, then you must be 'equal' to me.
'Alright!　Sister Yotaki, it's a 'promise'!

　Immediately I took both of Youtaki sister's hands and nodded back, bouncing them up and down.
　Sister Yotaki also smiled bitterly, but she certainly nodded back, "Yes, it's a 'promise' ......," she said.

''I will ...... just go harder for that. I'll get a little serious and stuff you up.

　That smirk contained a killing intent, in abundance.
　Furthermore, along with the intent to "kill", the "thread" wraps around my entire body.
　A chill runs down my spine as the inhuman touches my body.

''It's been years since I've gotten even a little serious. I'm glad to see the tension in this warm, otherworldly world. Tiara--

　I was wrapped up in a too thick white 'thread' and the light of the world was cut off, and it became pitch black in front of me. I thought to myself that this was the 'human darkness' that sister Yotaki had that I wanted. I'm glad that I was able to drag her out on my own without letting her meet with Tida.
　Towards me, Sister Yotaki declared.

''--You will definitely become your brother's 'one and only destined person in the world'.

　My body trembled.
　The reason I am alive now is because my sister Yotaki has chosen to 'kill' me because she is concerned about my future. That's why my instincts as a living being continue to make my body tremble. I can't stop trembling. It won't stop, but--

　-- Now we're not na na na na (・・・・).

　I still had a loose mouth.
　This is not a farce. This was a genuine fight for our lives.

　At that time, the word "duel" that I read in a book came to my mind.

''Come on, Yotaki-sister!　...... This is already a duel!　It's a duel between me and sister Yotaki!
Duel?　...... Surely this must be a duel, since you've made a 'promise' with your life on the line. Huh. Really, Tiara loves this kind of storytelling.
'Hee hee!　Yeah, I love it!　To read the duel and to fight the duel--

　I finally burst out laughing.
　The fun must have outweighed the fear.

　My sister, Yotaki, also laughed at me, "Hmmm.
　I could clearly feel a connection with her that I hadn't felt before we left.
　It's not just a matter of form, but also of substance, as the name "Yotaki Sis.

　--The first thing that comes to mind is the fact that it's not just a matter of time before you'll be able to get your hands on it.

　The rules of that duel are not so difficult to follow.
　All you have to do is to make "Kirikame," the referee, admit that you are in love with him.

　The points to note are also easy to understand.
　First of all, you must never get into a good mood (・・・・・) in front of your master. Never give the world an excuse to say "I love you" even in the absence of your master.

　The important thing is the ability to act.
　Like an actress in the theatre, I must play the role of the "innocent, innocent sister who adores me as her apprentice". I must emphasize that I only like my master as an apprentice, and I must do my best to make every confession in Fania a misunderstanding of my master.

　Fortunately, that kind of misunderstanding has been common in Master's life (no doubt, sister Yotaki will be involved), and he's already finished acting during the return trip from Fania.

　So.
　By the rules (rules) of the duel, we are from here on out - it's all theater.

　This is the story behind the scenes that I wanted my master to know.
　Of course, this is not the only thing hidden behind the scenes. There are still more truths (things) that cannot be seen from a master's point of view.

　I hope you will see it in "Magic" a thousand years from now.
　Even if Master was able to anticipate the last 13 years of the new calendar like you did, there will still be more truths to come from the first year of the new calendar to the 13th year of the new millennium. Until the birth of Rustyala Foods Yards, in that order--

　Please let my master and my daughter both impose the 'price' of the 'magic' that can kill sister Youtaki on me.
