Around the time of Toa's fifth birthday, the World Mirror appeared in the gardens of the Demon King's Castle.
　At that point, Toa and Rosalia were the only people in the present world who knew the memories of the end of the world.

　In the world, it had been eight years already since the lost corner of the Eight Gorges - Dames Ardan had once collapsed and began to call itself the Damescale Empire. It was the madness of Uranos.
　The two of them understood, through shared memories, that Adolf was lurking behind it.
　Twelve more years would pass before Greiberg would summon the other world.
　Rosalia and Toa had things to do before then.

　The Queen of the Demon Kingdom of Chastain - her best friend, Cassandra, enlisted the help of the Queen of the Demon Kingdom of Chastain - her best friend, Cassandra, and Rosalia, who decided to persuade the King of the Demon Kingdom of Lagparos - Ignotas. She didn't have the inherent skill 《Domination》 that only resided in the direct bloodline of the Demon King, and she couldn't share her memories like Lucius. The most effective means that seemed to be the most effective - sharing the memories of the end of the world had no other choice but to convey them in words.
　The goal was a treaty of friendship. Beyond that, it was the unification of the Demon Kingdom.

　On the other hand, for the Lucius of that time, unification of the demon kingdom was unthinkable and impossible to think about immediately. It was impossible to understand Cassandra's national government that kept the Ninaju tribe, which was incomprehensible to him. The demons of Ragpallos, who are a mixed species with humans, are discriminated against by the demon tribes of the three countries because of their inferior human blood, and they themselves detest humans. The same is true for Ignotus.
　Lucius couldn't trust those who were at the mercy of the fences and flaws. Aside from Cassandra, there was no hope for Ignotus.

　After granting Rosalia's offer of an audience, Ignotus took her suggestion that they should join hands with each other. It was only strange to Lucius, and it was natural for him to think that there must be something behind the scenes.
　But there was no backstory to Ignotus.

　Rosalia had guessed all of the plans that Ignotus was about to embark on at the time.
　It was to send Rosalia to her death, to frame Cassandra for her murder, and to arrange for Shastain and Ursula to never hold hands with each other again in the future. This is exactly what happened in the end of the world. Rosalia was killed, and Toa suffered a serious illness of amnesia and multiple personalities from the shock of losing her sister. He was forced to live in confinement in the castle until he met Masamune - a life of confinement.

'I can see the future,'

　That word from Rosalia, standing in the center of the hall, left Ignotus in awe.

'There is no future for you if you continue to move with malice. That's true even for your precious brothers. They will die in the chaos. And you won't be there for them. They're all going to die.

'It's a threat, Rosalia it's true I'm going to kill you, I'm not wrong. But whether you know it or not, it ain't changed, not even a bit of shaking?

'This is not a threat, Ignotus, this is for your sake and our own. Twelve years from now, the world is going to be visited by otherworldly people. If we don't truly join hands, the world will surely come crashing down. Humans, beastmen, and demons will all perish, and the world will be a world of demons only.

A demon? .....

Sooner or later there will be a king with the power to destroy the world. Everyone will be powerless before him and the demons will be unleashed.

　Ignotus is not pure enough to swallow quickly. Standing on either side of the throne, Felsen and Bishas waited for their brother's decision.

''By the time Toa fully masters the Domination, I will prove it is not a lie by sharing my memories.

　And for now, the audience is over. Ignotus promised not to touch her until then.
　Rosalia was excellent at "Emotional Sensing". From that, it could be clearly seen that Ignotus was not telling a makeshift lie.

　Lucius, Cassandra, Ignotus, and Rosalia. And Toa. It didn't take long for these sides to sit around a round table together.

''We'll establish a friendship between humans and beastmen first.

　Rosalia proposed a treaty of friendship with three certain countries.

''One is the fortress city of Artemias, the second is the royal capital of Rashausen, and the third is the beast nation of Neitzert-Katalia.

　In front of the three who were unhappy with their grasp of the story, Rosalia spoke of a memory that only the two of them still knew.

'Somewhere in the twelve years before Toa turns seventeen, a world mirror will appear to the three of them, Sufilia, princess of Artemias, Sierra of Razhuisen, and Nem, the white cat tribe of the Beast Nation.

　They had already talked about the World Mirror that appeared in front of Toa and Rosalia. What the three of them, who didn't know their memories, wondered was why the World Mirror would appear to those three.
　Rosalia explained that it was because the girls were friends of the King, the sender of the World Mirror.
　Masamune had set the time of the World Mirror's occurrence. Sierra and Sufilia were both between the ages of seventeen and eighteen, and Nem was between the ages of four and five.

　The conversation moved further into the matter of the Empire and the Underworld.

'In time, I'd say the Toa are about seventeen, and the Empire is about to attack Razhuisen. Before then, within ten years from now, the Beast Nation will fall into the hands of the Empire.

　Rosalia's plan is as follows.

　First, we'll ask the Khalifa who lives in Biyoment to break her Oblivion spell. Then we'll go with her to the Underworld, and after Zephyr's body is recovered, we'll begin to create the object.
　If Zephyr comes back to life, Adolf will be able to take care of himself. Then the Empire and Uranos will automatically stop, too.
　If Uranos stops, the Beast Nation won't be attacked, and Nem's parents and others will be saved. Razhuisen won't be attacked, and Sierra's sister - Hilda - won't die.
　There is nothing we can do about the damage that has occurred to date, but we can deal with what is going to happen.

　The three sons of Uranos were also dealt with at the same time.

　The canyon city of Palustria--Jade, and the extremely cold land of Modhern--Laj.
　And Reinhardt, who is the oldest member of the current White King's Knights of Radshausen.
　A decision was also made about their repatriation to the Empire.

　The meeting ended with a few last minute issues, including Pascantin and Utopia, Enumasan and Ixos.

　While the talks and plans were going on, Rosalia had one concern. It was about the war that Greiberg was waging.
　Johannes' turbulence triggered Graysberg to start a war to seize the territory with his eye on the demon territory. The first to attack was Lagoparos, and Ignotus returned fire to pass the time.
　The purpose of summoning brave men was to replenish the magicians for the demon race. It began with the desire for a strong wizard who could defeat Ragpallos.
　But now that a friendship with Ragpalos was being established, Ignotus would not deal with Greberg, no matter if he attacked him. He too has changed.
　And that seemed to rob Masamune of a future to be summoned.

　But there was no problem.
　It came from Alford's words in the End Times - the Greberg bloodline was rotten to its very core.
　Johannes, after his turbulence, began his invasion of Ragpalos.

　And now the time has come--.







　Hidaka entrusted everything he had seen to him. The same goes for Nem's parents, Sierra's sister and Toatrika's sister.
　As for Rosalia-san, he was surprised to hear that she was the current Demon King of the Principality of Demons.
　The world was reborn through the last prank he had performed.
　And it became the real other world he wanted to see, and now it's spreading before my eyes.

　But is this really the world you wanted and wanted to see?

'Master, Nem is called Nem.

Master?

'Masamune, my name is Sierra. I'm currently a White King's Knight in a country called Razhuisen...

'Masamune, I am a Sufiria. I am your wife.

Hey, Sufilia, you're lying.

I'm not lying, Toa.

　Hidaka-kun is in a daze. Was it the same for you in the past........

　I found Saeki behind a pillar. Beside him, Kida is also there. He said something about the two of them apologizing for what happened at school, and since then, he's been watching for an opportunity from the shadows like that.

'Master, this is Nem's mother and father, and this is Mimi.

'Masamune, this is my sister, Hilda.

'Masamune, I'd like you to meet my sister.

It's nice to meet you, my sister, Rosalia.

Masamune, I am an only child.

　The Hidaka-kun in front of him was outwardly the same as he was in his memory. In the world of the end, he was 27 years old, but his growth stopped when he was 23 years old.
　His sharing of memories through his World Mirror and Domination was more profound than showing or telling. The content of the message would vary slightly depending on the person to whom it was communicated.

　To me, Ichijo Yukimura's memories were conveyed.
　The way it is communicated is by recreating the memories from a first-person perspective. However, that is limited to me.
　I was next to him in the end world until the end. He allowed me to experience my memories of that time in the present.
　So the current me should be the same as Ichijo in that world....
　The reason I can't assert that is because I can't prove it myself. I can't say for sure that what I think about and what I think about in the other world are the same.

　My memories of Hidaka are not told in the first person, but in the third person perspective. It's like entering the world of the movie and following the protagonist's back.
　In other words, I kept it to the point of recognition.

　He didn't share in the thick of it.
　He didn't share anything intense, he put something very separate between us and himself, a natural stranger.
　He didn't let himself be understood at last. He could have.

　Mr. Toatrica, Sierra, Mr. Nem, and Sufilia - the current situation must be happy for all four of them.
　But sometimes I feel as if I can see the other side of their smiles, and there are moments when it looks very lonely. You could call it a sense of loss, but they should be happy, and each of their smiles should not be false. But I'm not convinced.

　I feel a strange sense of emptiness.
　Then there's a sense of closure, of being trapped in a world of isolation that I'll never get out of again, and I shake my head in frustration, telling myself in my mind to come to my senses.
　There was nothing left but a blank space, and when I crossed it, there was nothing but helplessness, and finally, a sense of weakness.

'I don't know, I don't know...'

　He is not Nito in front of me. Nor is he Amadeus. It's definitely Hidaka Masamune.

　Are you really, this is the right thing to do....
　I can't help but want to hear the answer to that question.

　You must have been able to see this scene.
　Here is everything that was lost from that world, and humans, demons and beastmen will join hands, and there will be no more discrimination or separation in the future than there is now.

　There is nothing here. There are those who have shared their memories, and that's all.

　But if you say you wanted it to be that way I get it. We'll pretend that it is.
　It's habituation that worries me. Will we ever forget about you?
　Will we forget about you, and will you be the only you in front of us?

"You won't be the only one here...

　I smiled as I suddenly remembered.

　Fighting together with Saeki in front of Aries, we tried desperately to protect you.　
　Hidaka-kun........that Saeki had asked you for help in a friendly way. That Saeki is the one.
　I don't know why I thought you weren't here, but I got the feeling that you were smiling.

　Here are three people who were never supposed to understand each other, me, Saeki and you.
　I'll admit that much, though I won't admit to anything else at all.
　But that makes you more of a hypocrite than me, is that okay with you? .........

　The hall and the vaulted ceiling.
　The otherworldly sky is blue and the clouds are flowing. .........
