"Uguo...... disgusting......

　The vision is of an endless white space. It seems that you have arrived at the space where the Colorless Demon King lives, but your memory of what happened before and after is a bit hazy. It's a good idea to have a good idea of what you're looking for and what you can do to help.

"--specs. No hard feelings, I hope. My space is inaccessible to the average person. I was able to get through some troublesome barriers, but the nature of the space made it difficult for ordinary people.

　The colorless Demon Lord beside me snapped his fingers, and the scenery around us changed completely. The world is given color and shape, and it becomes a place you've seen before.

...... is the office that 'I' used to rent for work.

　The interior is the same as the small office I used when I was working as an individual in Japan, on Earth. The only difference is that there's no view outside the window.

It's a world I've built from memories I've read from you before. Electronic devices? I can't use electronics or anything like that.
...... Looks like it.

　I tried to press the power button of the computer, but there was no response. In the first place, the LEDs that illuminate this room also give me a strange feeling. If you observe carefully, you can see that this is a space that has been recreated by tracing human memories.

I've prepared an environment that you are familiar with so that you can think a little. Here, this one should work just fine.
There's something I've missed again.

　He threw me a cigarette of the brand I used to smoke and a hundred yen lighter. If you can analyze your sense of taste and so on, you should be able to reproduce these things.
　When I tried to light one of the cigarettes, it tasted like a cigarette, but it was clearly uncomfortable and made me feel sick.

The reproduction should be perfect, right?
"It's weird that a cigarette I haven't smoked in a while tastes so good. If you don't smoke for a year, you have to start all over again to get used to the taste.
You sound like some kind of troublesome woman.

　I was in a position to choose what to depend on, so I'm not that attached to the cigarettes I started with. When it comes to relieving daily stress, I'm more comfortable with coffee, sweeteners, and other things that don't make people uncomfortable.
　I even thought about adding cigarettes to my routine for a while, but I stopped because I thought it would be disastrous if I ran out of cigarettes in an emergency.

I don't have to do this, I'm always in great shape with a stinker like you by my side.
"That's good to know. Now, let me give you a brief history.

　The colorless Demon Lord sat down on the visitor's couch and pulled out some popcorn from the empty space. Since it was also from the earth, it must have been a disguise created by magic. It may be useful as a diet food.

You know what Shigeya Yukura is trying to do, right?
Should I start from the beginning? It's a bit of a long story.

　.

　My sister and I were part of a family that lost our country. At that time, there were wars everywhere, so it wasn't that unusual.
　But we were not born in despair or anything. Some countries were willing to protect refugees and cooperate with each other to live together.
　In those days, even if you won a war, it was very difficult to maintain the territory you took. That's why they took in refugees and left them to manage and protect the land near the borders and on the frontiers.
　The country gave us a place to live, and we gave them what we could.
　I'm sure they didn't want to leave a legacy of royal blood or a defunct country, but my sister and my family were a bit of a fixture in the village we were assigned to.
　Whenever there was a problem in the village, my father or my sister would take the initiative to visit the village to ask for advice and solve the problem. Not to mention my father, my sister was well-liked by everyone.
　Me? I was a gloomy guy back then. Whenever I found time, I'd wander around outside the village picking up rocks and stuff. It was one of my sister's jobs to find me and bring me back to the village while giving me a lecture.
　In the midst of this repetitive routine, he suddenly appeared. My sister and I found Yugura who had collapsed in the forest near the village.
　Her clothes and face clearly showed that she was from a different country. My sister thought he was a foreign spy or an exile and brought him back. When he woke up, he couldn't even speak the common tongue, but one day he suddenly became fluent. The Kuro Sister realized that this was due to magic and saw through Yugra's talent.
　Yugra told her that she came from another world and that her goal was to live comfortably. I was skeptical about the other world thing, but when I saw the extraordinary magic he was learning, I had to believe him.
　Since he was not too toxic, he became less cautious and came to live with us.
　He was the kind of guy who would freely use his power to help and never ask for anything in return. He was regarded as a freak, but he was soon accepted by the village people. At least at that time, Yugra was able to live the life he wanted.
　But the times did not allow it. Neighboring countries grew stronger and tried to invade our country. We were prepared for that to happen one day. ...... The reality was much worse.
　The country that was feeding us used our village near the border as a trap. They deliberately made a hole in the protection that we had worked so hard to prepare and lured the enemy in. They forced us into an unfavorable state of engagement and unilaterally opened fire on us from outside the village. The village was surrounded and finally massacred without distinction between friend and foe.
　With the help of Yugra, my father and my black sister began to influence the neighboring villages and towns, and this is what the government did to the village. The thoroughness of this was terrible. Yugra was lured out of the village and was almost assassinated.
　Many of our people died. My father and mother died. My sister was badly wounded and everyone despaired she had no chance of survival.


　But Yugra rushed to the scene and used a resurrection spell to bring back the Kuro Sister as the Demon King.
　Everyone was happy at that time. The black sister who was not supposed to survive came back in good shape. It's a small price to pay for not being able to say her name.
　But if you know anything about the history of this world, you know what happened after that, right?
　My body is better than before, but my sister is still mad. She was angry at the country that had betrayed, used, and disposed of her, and she wanted the power to take revenge.
　Yugra gave the power to the black sister. She gave her the power to destroy the world, the power of all the magic she had created in hiding.
　Yugra was also angry at the country that betrayed us, and she didn't care if Kuro Sister took revenge on us and destroyed us. She didn't have any resistance at that time.
　She turned the surviving members of the village into demons and destroyed the country. At that time, the world didn't know about the appearance of the Demon Lord, so they only knew that the country they were aiming for was suddenly destroyed.
　They came to invade and take the land. The Kuro Sister tried to fight them all off, but ...... Yugra stopped her. The village was already ruined. She said there was no need to fight now.
　I'm sure you'll be able to understand that it takes time for a group of only a few dozen demons and the demon lord himself. So she decided to move to the edge of the continent and create a demon world to create soldiers called demons.
　Yugra feared that the hatred had not disappeared from the eyes of the black sister, even though she had finished her revenge. She was angry not only at the country that betrayed them, but also at the world and all the people living in it, who were still fighting against each other.
　I tried to persuade her a lot, but I couldn't bring her back. She had the power of revenge, but she had no reason not to use it.
　In order to get the power back from her, Yugra decided to find a way to make her human again. However, the reanimation spell that transcends reason and creates a human into a demon king was too powerful. If I just lifted the resurrection spell, she would just turn back into a corpse like Raheit.
　She continued her research while creating many new Demon Lords in the pretense of increasing her friends. In order to prevent the Kuro Sister from bearing all the sins, she made a demon lord out of someone who would be an enemy of the world.
　The rest of the story is as told in history. The Kuro Sister, who could not be restrained, attacked humans, and other Demon Lords took advantage of it, and the world was almost destroyed.
　Yugura stopped her research, became a Demon Lord herself, and eradicated the Demon Lords once.
　But the Kuro Sister became too strong. That's why even Yugra who became the Demon Lord couldn't handle her. She could hasten her resurrection by her own will, just like Raheit did.
　That's why Yugra used the Demon Eater to seal the Kuro Sister. To buy time to find a way to make her human again without paying the price of removing the resurrection spell.

　◇ "My sister Kuro destroyed everything.

"If she destroys everything, there will be nothing left. Even if the black sister returns to normal, there is no future for her. So it was a last ditch effort on Yugra's part.

　The colorless Demon Lord speaks sadly. This is probably because he could not interfere in the relationship between Seiya Yukura and the Kuro Demon Lord.
　He couldn't stop his sister from trying to destroy the world with a vengeance. I could only leave everything to Shigeya Yukura. The reason why I am still helping Shigeya Yukura is because I want to help him save the Kuro Demon King, even if only a little.

I'm not sure if you'll be able to find a way to do this, but I'm sure you can.
"Yeah. But halfway through, Yugra decided to change his approach. But halfway through, Yugra decided to change his approach. Instead of canceling the reanimation spell without a price, he said, we have to go back to the time before the reanimation spell was used.
So you're saying we can use space-time magic to go back in time?
Yeah. But the first time, you son of a b*tc*, God warned me. And Ygras was killed for rebelling against it.

　If that's all there is to it, then the resurrected Seiya Yugura will find a way to save the Kuro Demon Lord other than through space-time magic. But instead, he chose to use space-time magic again.
　Something must have happened during this time. That is--

"So after the resurrection, you decided to use space-time magic instead of finding a new way?
Apparently so. There must have been some divine interference, but Yugra said he 'silenced' it.

　I silenced the gods. ....... I don't know how he did it, but he succeeded in getting the god who created this world to concede. It's a good idea to have a good idea of what you're going to do, and how you're going to do it.

I'm sure you'll be happy to know that I'm not the only one.
"It seems to be able to send the memories of the practitioner to the past. In other words, the memories of the current Yugra will be available to the Yugra we just met.
History would be changed for sure.

　The past Yugura Seiya who got the future memories will never make the Kuro Demon King the Demon King. If he did, no other Demon Lord would be born, and the current great powers would never be born. A time paradox would occur and this world would be rewritten as a new world.

I've heard that they've made some adjustments so that one more person's ...... memories can be delivered to the past. I've heard that it's a lot quicker to alter history that way.

　If you want to save the Kuro Demon King, it is better to have a close collaborator than to have Seiya Yukura alone go back in time. It's a good thing that you're not the only one who has a problem with this.

You are fine with that, aren't you?
"It's definitely better than having my black sister stay like this forever or broken. But I don't think it's ...... right to start all over again. I'm sure you'll be able to come up with one of your own ideas .......

　There is no such thing as a tragedy. But to pretend that tragedy doesn't exist is also a tragedy.
　Nevertheless, it is natural for the people involved to want to start over if they can. Shigeya Yukura has the means to do so.


　That's the same thing as not being able to convince the Kuro Demon King. It's like trying to convince someone who has the power to take revenge not to use that power, but how can you convince someone who has the power to start over not to start over?

As for me, I don't want to lose the present. If history changes, everything I've done in this world will have never happened.

　If the Demon Lord hadn't been born, the current great nation wouldn't be born. The Bastard of Yugra will also cease to exist. That means that the Iliad and the others will disappear from this world.
　It's not entirely impossible that they could be born in a different environment, but at the very least, the lives they've lived so far won't be included in that environment.

That's what I'm talking about! That's what I'm talking about! I called Yugra just before she came here, so she should be here soon, right?
"What about ......? No, no, no, wait a minute! I'm not sure what to do. There's no preparation then.
No way. You're busy, and you call me for something urgent. ...... Wow, what's with the decor? What's with the decor? Who is this guy?

　It's a good idea to take a look at the website and see if you can find any useful information.
　There was a figure of Shigeya Yukura that was no different from the figure I had seen in the Index of the Brave.

"I...

　When I tried to talk to Shigeya Yukura, I realized the moment I looked into his eyes. I can't persuade this guy. No matter what I say to him, I can't change his beliefs.
　By looking into a person's eyes, you can sense to some extent how much he is willing to act. Such things as resolute attitude and firm determination are easy to see in the eyes.
　This is particularly evident in Seiya Yukura. He has tried everything, understood everything, and accepted everything.
　I have seen similar eyes in Japan. A cunning monster who avoids making enemies, even those who are reckless enough to follow the path of evil. A being that has no choice but not to fight.
　He may be younger than me in terms of age, but the number of years this man has faced his own path must be tremendous.

It's terrible to treat him like a grandfather. I mean, he's Japanese. I never thought I'd meet someone from my hometown here.
"You can even read my thoughts?

　Yugra's secret technique for detecting the truth of lies. It's done by observing the fluctuations of magic power in the other person's body. In my body, there is the magic power to maintain the possession technique for conversation and the magic power of the Kuro Demon King.
　Since it was Seiya Yukura who passed it on, it is only natural that he can use it. I thought there was more to it than that, but I didn't know if he could see through people's minds this clearly. .......

"Oh, that's right. Kuro called you. That's why you don't have any magic of your own. I hadn't explained that to her. But even if I had, I wouldn't have had time. How did you defeat Scarlet in such a state?

　This time, she told me something I hadn't even thought about. Perhaps he had read my memory. It's almost like a super-compatible power to Duvraeus' Lost Belly, but I didn't feel like he did anything to me.

He said, "Can you please not look inside people's heads so much? I don't feel good.
"Oh, sorry, sorry. I'm always curious about what people are thinking when I see them for the first time. Now that I know you're harmless, that's enough. So, you were called to the Tedral to convince me, right? Are you leaving?

　I wondered who Tedral was, but I guess the colorless Demon Lord looking away beside me was that Tedral. He's not a demon king, so he has a name, right?
　But it's a dead end within a minute of meeting him. He can't be swayed by words, but if he can see through your mind and read your memories, there's no such thing as psychological warfare. If you believe Shigeya Yukura's words, he may not be reading you now, but if he senses even the slightest sign of disquiet, he will read your memories again and that will be the end. As the saying goes, to Shigeya Yukura, I am nothing but a harmless civilian.
　Then, what to do? Do I just keep my fingers in my mouth and wait for the world to end?

No. I've given up on persuasion, but I'm not leaving yet. I may not be able to convince you, but I can make suggestions.
Oh, so the Tedral is counting on you. That's an interesting turn of phrase.

　No kidding. What do you think we've come all this way for? I'm not going to let you unilaterally make everything worthless. Even if I know it's impossible, I'll struggle to the end.

"Yukura Seiya. Before you end this world, let's play one game.
