Scary, scary, scary flying...
"Unnuuuuuuuuu....

　Engineer Erca is mumbling to himself as he squats down on the ground, and Fenrir is slumped beside him.
　Was it that scary? It's a bit like riding in a high-speed airplane with glass walls all over the place, fluffy and fluffy... a bit scary, huh?
　We arrived at our destination, the Kingdom of Primula, in about five minutes, but it's been in that state for more than ten minutes now.

It's a good idea to show us to the castle, for God's sake. A battle is underway, right?
Ha. That's it. We have to hurry!

　Putting back the glasses that had slipped off, Engineer Elka came to his senses.
　I'm in my current location on the side of the road, a short distance from Primula's royal capital, Primula, and if you walk from here, you'll be able to enter the royal capital in no time. It's easy to enter the capital from here.
　When we arrived at the capital, Engineer Elka showed the guards there something that looked like a card, and a six-wheeled golem carriage was immediately prepared for us. Apparently, it's not a lie to say they're getting to know each other.
　After getting into the Golem carriage, we were led by a knight of Primula and headed for the royal castle.
　The people in the castle town seen from the window seemed to be somehow tinged with shadows, perhaps because of the creeping war.
　When we arrived at the royal castle of Primula, which is larger than Brunhild's castle, a well-tailored, well-built, bearded man came running towards us immediately. Combined with his body shape, he's running hard, but I can't help but feel that there's something comical about him.

''Elka-dono~!
Hey, Sous Chef Avery.
"It's been a long time.

　While catching his breath in front of us, the man in his fifties, known as Chamberlain Avery, was shaking hands with Engineer Elka and his attendant, Fenrir. The handshake, or rather, Fenrir's, looked like a 'hand', though.

'You have come well. His Majesty will be very pleased. Now I say that the Primrage will be able to fight to its full strength.''
"Primurage?
It's the royal family's very own golem. It's an ancient aircraft, the Legacy. I perform maintenance on it every few years.

　I couldn't help but interrupt, but the chamberlain, Avery-san, turns to look at me.

'Huh?　Who is this man?
The helper. Maybe we can stop the invasion of the Divine Imperial Army.
What did you say?

　With his eyes wide open, Samurai Master Avery froze in a pose that looks like a kabuki actor cutting off his own pose. His every movement is comical.

"Will I be able to get an audience with His Majesty soon? I would like to ask you to meet with His Majesty in an informal setting. It might be a bit complicated to discuss.
I see. Be with you in a minute!

　Thumping himself in the chest and coughing, Chief Chamberlain Avery runs again. That guy is that one, vaguely reminds me of Humpty Dumpty from Mother Goose.

'Fuyao-kun, why do you think I believed your story?'
"...?　That's because Regingrave it wasn't because you showed him the frame gear?　Also, was it "The Black Crown"?　Because you knew what those golems were capable of?

　He twisted his head, unsure of Engineer Erca's intentions for saying such a thing so suddenly.

'That's certainly part of it. The other reason is because of what happened in this country. After the destruction of the ancient world war 5,200 years ago, many new countries came into being, but this is the only country that has survived from that time until now.

　Ancient World War........ It was a war that involved the world led by two ancient powers? As I recall, the underworld collapsed once due to a fierce battle in which various Golems were deployed.
　Civilization was lost, the technology to create Golems was lost, and the world was slowly rebuilt with the few remaining operational Golems... or was it?
　''5200 years ago, that's before the invasion of the Freys in the surface world 《here》.......

It is said that in the world after the fall of 5000 years ago, a man appeared in this land where many tribes were fighting each other. He spoke an exotic language and had magical powers. He spoke a foreign language and had the ability to use his magic, so he was welcomed by one tribe, and one by one, the surrounding tribes became his followers. That was the first king of this country. The king said to his friends and acquaintances, "I am not of a different world from this one. I'm from a different world than this one.
Wha....?

　What do you mean?　The first king of this place was an alien?　No way....

The country's name is Primula, which was the name of the tribe at the time. The name of the country is the name of the tribe at that time, not the king's. The name of this country's royal family is the "Parellius" royal family. The first king was named 'Lelios Parellius'.
Parellius...?

　Aelyrius Parellius, a wise man of time who existed in the ancient kingdom of Partheno five thousand years ago. A wielder of space-time magic and the creator of the wards on Parellius Island.
　What do you mean by that?　Wasn't the dimensional gate he was trying to build on Parellius Island unfinished, so he couldn't cross into the underworld, this one?　No, it just lacked magic power, but it was almost complete........?
　If the 'Black Crown' or something like that appeared in our world and then returned, is it any wonder that someone crossed over with it at that time?

You must know something about that, yes?
I know the name Parellius. He is a user of space-time magic that existed in our world 5000 years ago. His name is 'Allelius' though. There's also an island called Parellius Island, where the descendants of this Arelius and his apprentice live.

　Perhaps this High Ancestor of the Parelius Royal Family is the son or grandson of Arelius Parelius.
　If so, the Central Imam of Parelius Island a distant relative who shares her ancestry with her.

''This is a bit........maybe we should bring someone from back then.
'What?　What do you mean?
'I'm sorry, can you just wait here for a minute?　I'll be right back.

　Leaving Engineer Erca, who was shifting his bottle-bottom glasses and crinkling his eyes, I returned to the surface world of Babylon in [Cross Space Transition].
　When I transitioned to the 【Hangarage】, mini-robots were still strewn about, carrying tools and materials. I can see Else's [Gerhilde] standing in the garage, and Monica, who is doing maintenance, at her shoulder.

'I'm sorry, Monica. Where is the doctor?
Huh?　Oh, if you're a doctor, Holle, there you are.

　Monica pointed with the spanner and the doctor was there. Lying on the floor, sluggishly sleeping or........ There's no....
　He's a kid by the looks of it, so it's not like he's smiling.

Let's take them off for a bit..........................

　I don't have a smile on my face!

Hey, come on, man, wake up. We have an emergency.
Huh?

　I tried to shake the dreamy doctor with a still unshackled grimace, but he turned his hand toward me with unsteady eyes.

'Mmmm.'
Mug!

　Suddenly, he holds my neck and takes my lips. I try to pull away, but she holds my torso further with her legs and hugs me and doesn't quite pull away.
　In the meantime, a small tongue invades and ravages my oral cavity. The sheer magnitude of her technique is........scary!

That's enough!
'Whew!'

　I forcefully pull it off and throw it on the floor. In a way, it was a close call........

Huh?　Where are my cuties?
'You've been sleepwalking...'

　The doctor is scurrying around, rubbing his head. I mean, I don't know if it's a girl you're dreaming about!
　Anyway, I'll tell you briefly what's going on, and then I'll return to the underworld kingdom of Primula again with the Doctor in an [inter-space transfer].

''Here you go.''
''Nwaaaaah!''

　Engineer Elka and Fenrir weren't too surprised by our sudden appearance, but the chamberlain Avery, who was in front of us, overacted and backed away.

''It's okay. This man is a user of transference magic.
Oh, really? Please excuse me.

　Chief Master Squire Avery is breathing hard, but keeping up appearances. This guy should probably become a reactionary comedian.

''So, is that boy from another world too?''
Oh. This is Dr. Regina Babylon. She's the one who developed the frame gear.
"This girl?

　This time Engineer Elka looks at Dr. Babylon with surprise. Well, I suppose it will be. It looks like a little girl in a drab white coat.
　I've cast a translation spell on Dr. Babylon before, so she should be able to converse with me without any problems. For now, I'll introduce you.

I'm sure you'll be able to find a way to make it work. I've heard that he's one of the world's leading engineers as a golem engineer.
Oh, yeah. No wonder. Regina Babylon. Nice to meet you. I've got lots of questions for you later.
It's Elka. I'm the one who wants to talk to you. The technology of our magical civilization is very interesting.

　They shake each other's hands, smiling wryly. Huh?　It's like I've made two people meet who would be bad to meet.... The words "Do not mix" on the warning signs for detergents and other products come to mind.

' 'And anyway, if you're all together, come this way. His Majesty will see you now.

　Still somewhat agitated, Chamberlain Avery urges us to start walking.
　As we walked down the corridor of the castle, I asked Dr. Babylon about the man who is said to be the first king of this country, 'Lelios Parellius'.

'Lelios ... ah, I think that man was the second son of Old Parellius. Like his eldest son, he must have gone into magical engineering and worked as an assistant to Old Parellius. But as I recall, I heard that he died at a young age...

　However, he wasn't dead, on the contrary, he was flying to another world and became a king there.
　It's a strange story, but it's a bit like my position, and I feel a strange sense of familiarity with it.
　In front of the door at the end of the corridor, two strong-looking knights were standing side by side in front of the door.
　Chief Chamberlain Avery opens the door and lets us through to the room. Of course, they checked me to see if I had any weapons-like items, but since my Brunhild was tucked away in [Storage], it was no problem.
　The room is massive and simple with a sense of history, creating an atmosphere of simplicity rather than solemn splendor.
　A man who was sitting in a chair at a desk at the back of the room stood up and came over to us.
　He was in his mid-forties, with a sturdy body, but not macho. I'm not sure if it's the so-called thin macho.
　He has short brown hair, a fine mustache and beard, and a face that is quite austere and manly. And on top of that brown-haired head, a simple golden crown was placed.
　This man is the king of this Primula Kingdom. In other words, he's a descendant of the wise man of the time 'Arelius Parellius'.

It's good to see you, Engineer Elka. Good to see you.
It's been a long time, Your Majesty.

　The two men conversed in a friendly manner and shook hands with each other. It was more as an equal friend than as a king.
　King Primula's gaze turns from Engineer Elka to me.

'Is this the one who can stop the invasion of the God Imperial Army?
Yes. We may be able to decipher the tablet left by our first king here. His Majesty once told me that he was from 'outside'.
Huh...!

　I could see that King Primula swallowed his spit at Engineer Elka's words. His gaze on me changed slightly, but eventually he quietly opened his mouth.

''htmzt/ioiuo kzttt/aeoui hkrtymn/iaioaii sstm/oieu srhnnk/oeaaia?''
What?

　For a moment, I didn't understand what he was saying, and then the king's eyes, which were turned on me, narrowed. But the same words came out from next to me.

''srhmh/oeaao u.'' Are those the words left behind by the son of Old Parellius?　Unfortunately, there aren't many people in our world who can speak the ancient magical language nowadays, right?

　The Doctor grins and speaks to the King with a grin. Oh, it was an ancient magic language. If you use translation magic, there's no way I can't speak it either.
　It was a good idea to bring the doctor with you.

I see. I'm not sure if it's a good idea. The ancient magical language, right? If you don't learn it, you won't be allowed to inherit the royal family.

　Huh. I wonder if the first king has always believed that his father, old man Parelius, would complete the dimensional gate and transfer everyone on Parelius Island to this world.
　It's painful to think that even though generations may change, he would surely come one day....
　Probably because he thought that the world he had been in, except for Parelius Island, which was warded, had been destroyed by Fraise.
　His descendant, King Primula, comes to me and offers me his hand. He seems to be a very frank king.

I'd like to welcome you. I am Rudyos Primula Parellius, King of the Kingdom of Primula.
"King Brunhild, Fuyuya Mochizuki. This is Dr. Regina Babylon.

　I shook His Majesty the King's hand that was offered to me. I couldn't decide whether the look of surprise on his face was in response to my title, the Doctor's title, or both.
