Rasperda Fortress was once a great fortress that divided the boundary between the two camps of humans and demons.

　It was said that whoever conquered it would win the battle, and since ancient times, many heroes and heroines fought over it and it became the stage for all kinds of heroic tales.

　It has disappeared.
　Without knowing what happened in between, it suddenly disappeared without a shred of evidence.

　If the fortress, which should have been the keystone of human and demonic struggle, disappeared, the rules of battle, which had been established as unwritten rules, would also disappear.
　It was expected to plunge into an era of chaos and warfare, but an unexpected person prevented this from happening.

　Arantzill, the brave man of the past.
　He was also a member of the Four Heavenly Kings of the Demon King's Army, Grampaza of "The Fire of Hell".

　The two who had already carved their names into legends while alive, and who had fought each other as fatal rivals when they were in active service, announced their intentions at the same time as if they were breathing the same air.

　--They said, 'We must stop fighting until we rebuild the fortress.

　Following their lead, a truce was signed, and for the first time in hundreds of years, the tension of warfare passed from the border area where Lasperda Fortress had stood for the first time in hundreds of years.

　Five years have passed since then....
　How is the construction of the Rasperda Fortress rebuilding work done?

◆

　.... it was still going on.

''Master Grumberza. I have just arrived with my replacement engineers, the dark general Lizete.
Hmm.

　The new Rasperda Fortress, which is in the middle of reconstruction, is a blatantly unconstructed structure with halfway through masonry and exposed timbers of the framework in some places.

　Since it's a huge structure, it can't be helped that it will take a long time to build, but it's still in the middle of the road after all sorts of twists and turns, with construction interrupted by various strange and unusual events.

　Nevertheless, for a time, there were even setbacks in construction. The reason why they were able to overcome these obstacles is because of their heroes.

　Granbaza, the former Four Heavenly Kings of the Demon King's Army's "kagoroki", has been busy even after he retired as the Four Heavenly Kings, and is now in charge of rebuilding Lasperda Fortress on the demon side.
　He stayed at the proposed construction site day after day and worked even more vigorously than when he was active.

''Come to think of it, Rizzet. You've finally risen to the rank of Dark General, congratulations.
'No!　I cringe when I'm in a position that's too non-talented like mine!　I'm afraid!
''Don't be modest. You are without a doubt the most skilled magician among those who joined the Demon Lord's Army in your generation. It's a good thing that you've been promoted to the rank of dark general when you're almost 40. Put your heart on the line.
..........

　Rizzet was a genuine Demon King soldier who had lived his life with a military career since he was a child.
　Therefore, it was a tearful moment to be praised by the legendary hero Granbaza, but he himself couldn't help but take the praise at face value.

　

''Upon arrival, Rizet. You are not allowed to fight at all here. I want you to make sure that not only you, but also your soldiers understand that.
Yes, sir!

　The history of the war between the demon and human races was long, and there were times when it was a muddy and bloody battle, and other times when it was a quiet stagnation.

　Even so, this is the first time that a truce has been clearly stated and signed. Therefore, both the human and demon sides are greatly tensed.

　They wondered when this first tentative peace would be broken.

　There have been crises in the past.
　The most dangerous time was when the attack by the brave Radie was discovered to be an attack on the Demon King.

You have a truce on the front lines and now you are attacking the Demon King behind it? The demon tribe was enraged, and tensions were high at the planned rebuilding site of Lasperda Fortress.
　It was the former heroes, after all, who prevented a violent clash.

Let's see who's in charge on the other side. It's not a good idea for you, a general, to have to negotiate a deal with a partner.
''Huh........?''

　Lisette's liver shrank at the opponent she was brought to meet as she proceeded through the construction site accompanied by Granberza.

　Because it was the human tribe's brave Arantzill, the human tribe's brave man, who was feared as the evil demon beast, the worst enemy of their demon tribe.

''A new commander for the demon tribe? ''You are the new commander of the demon tribe?
''Yes good........?''

　Lizete's hand trembled as she shook hands with him.

　The generation that is about to reach the age of forty is the generation that experienced the former Arantzill and Granbaza era as a real battle.

　The fierce battle between the two, who were once the active hero and the Four Heavenly Kings, was so fierce that an ordinary person would be cut to pieces just by coming close to them.

　It is said that there was no one who was not afraid of the enemy's great hero, Arantzill, who rampaged in the form of a beast when it came to battle.
　Rizzet also faced Arantzill in battle for a moment in his youth, and from that day onwards, he still has nightmares, even now, without ceasing.

　She never thought she would be able to meet again so peacefully with such a person of fear itself.
　It was impossible not to feel the strangeness of fate.

'The new Rasperda Fortress is now sixty percent complete. It's not a fast pace, but it's progressing steadily. I need your help to complete this fortress.
Gladly!

　They are essentially enemies, but they waved their voices.
　That should be the efficacy of a hero, regardless of the human or demon, but it inspires those around them anyway.

　There are two heroes mixed in here at the same time, who will surely be the stars of an era.
　Since those two people advocate cooperation, that was something everyone would follow.

''The work will also progress once the new demon side's engineers come in. How do you want to allocate them?''
The demons can use ground magic. I think it's best if we just let them shape the general idea and let the humans do the details.
"The human craftsmen are very meticulous. Many of the demons posted here also claim to be enlightened.

　The meeting was a familiar one.

　The seemingly impossible task of rebuilding Lasperda Fortress could be accomplished by these two heroes.

　Do they still want to build a new legend at such an old age?　
　Lizet shuddered at the prospect.

''I admire you!''

　Then he shouted.

''You guys are leaving behind countless legends even in your prime, and yet you're willing to join hands to create the next legend at the end of it!　I admire it!　I'm proud to have been born in the same era as you!　As a witness to a legend!

　Lizet, who was a sensitive type from the beginning, was no longer filled with the supremacy released by the two heroes.

''This time the commanding officer is bothering you...?''
Don't say that. They're easily moved.

　The old heroes didn't seem to be fazed in the least.

'Don't be so awed, Rizet. 'Don't be afraid, Rizet, we are the same person, Arantziel and I. We are not special. We're not so special.
'That's right, it's just that we're the ones who've gone under the radar and have a strong causal relationship with each other through the history of the war. I didn't think we'd be working together this late in life, though.

　Then the old men look up at the new fortress.

'What a fate that we, who have spent so much time fighting, should finally be in the business of building something. But that also seems to be a meaningful thing...
Maybe it's atonement for the sins of those of us who have spent most of our lives fighting. At the very least, I hope that we'll pass it down to future generations with the sight of our completed fortress. That even those of us who have fought together for decades can finally hold hands...

　Seeing his words, his standing, Lizet cried tears.

　This is the figure of a complete hero. The end of a hundred battles, even hatred can be overcome.
　The truth that the two warriors showed me made me feel that the world is beautiful.

　Then..........

''Grandfather!

　Someone came.
　A child running at a tremendous speed.
　The child, who was approaching at a speed that even a horse wouldn't gallop at such a speed, stopped in front of both Granbaza and Alanziel.

Grannnnnnnnn?
''Oh!　You came from Lax's village again?　Have you come to see us, Grandpa?　My darling!

　For a moment, Lizet didn't understand what had happened.
　The voices of the heroes were too prodigal.

''Um........you two?　And the child?

　Fearfully, Lizette asked, and immediately objected....

''It's my grandson.''

　The answer was.
　I was slightly unable to follow my understanding.

'What, grandchildren?　Which one?
"My

　Lizet is increasingly confused by the arguments from both sides.
　It's not a situation of one grandchild and two old men. The parents' fathers would only have to get each of them together.

''What?　But speaking of Lady Granberza's children, that a**h*le Bashbursa?　Was that guy married before he was born?

　The confusion doesn't stop, but Rizzet instinctively decides to match the conversation here with the execution that has risen to the level of a general.

'No, when you put it that way, you're a brilliant-looking child. As expected of the grandchildren of both men.
No, no...! I know, right?

　The two of them ride around in transparent flattery.
　There.

''Speaking of which, I was wondering...''

　Gran Gran said something that shouldn't have been said.

'Who's stronger, Grandpa?'

　At that moment, the atmosphere of the place changed.
''I will win my grandson's respect,'' an intense will came from two directions.

''Um, both of you?　Why are you so eager to kill?　Where is the noble spirit of peace?　Why are you trying to fight to decide who's stronger again?

　And Rizzet has learned.
　His nemesis, he said, would always be his nemesis, no matter how far he went.
