Seras’s heart pounded fiercely.
It was because of what she’d heard as soon as she returned to the capital.
[Seras-nim!!]
[Chief Aide, grant me an audience with His Majesty at once. I have mountains of things to report….]
[It concerns that matter, but His Majesty wishes to hear the report at night. In his bedchamber, just the two of you.]
[……..!!!]
‘That Leo!’
She couldn’t help but be shocked.
Even if she was a guard knight, Seras was a daughter of a noble family.
To bring her into his bedchamber at night meant…
By medieval standards, it was a royal way of saying, “I choose you,” or “You’re mine.”
Thanks to that, her face flushed crimson.
Her complicated thoughts were also washed away, turning completely blank.
Right now, she was no longer a loyal subject agonizing over a military crisis, but a maiden blushing at her impending first experience.
“Captain? I understand you’re shocked because of that, but what can you do? Please calm down now.”
“That’s right! It’s on us this time, so let’s have a drink and shake it off!!”
“Let’s stay up all night today….”
“Ah, no way!! Absolutely not!!!”
‘These guys are so clueless!!’
Of course, she didn’t dislike it.
Seras was a woman harboring affections for him.
She couldn’t express it due to the difference in their status, but she had liked Leo, her childhood friend, since they were young.
-Rummage, rummage.
‘Not this, and not this… Ugh, I should have bought some cute and pretty clothes like the other young ladies!!’
Instead, she was busy choosing clothes.
She spent almost an hour wavering in front of her meager wardrobe.
She was agonizing over what he would like.
In the end, she chose a plain white slip, a mass-produced undergarment from Millenia, which was very much like her.
“…..”
‘Should I have gone to the store to buy something during that time… Ugh, but if it’s obviously new, he’ll tease me, saying I was really looking forward to it….’
-Rustle, rustle.
And so, the night finally arrived.
Seras’s figure rushed towards Leo’s bedchamber, like a concubine.
Apart from her shyness, her stride was so bold that she was truly the epitome of a knight, but…
-Creak.
“…Your Majesty, as you requested, I have come for the report.”
“Report? I didn’t realize you were so clueless, Seras. A man and a woman alone in a bedchamber at night, do you not know what that means?”
“Th, th, that is.”
“Come, lie down. Share the night with me.”
“……!!!?”
‘What’s wrong with him!?’
She couldn’t quite come to her senses at Leo’s bold confession.
Even more so because she thought something like this would never happen, given his personality.
“Ah, I understand….”
‘I, I, I’m going to be with Leo, with Leo, from now on…!!’
Her steps faltered as she headed towards the bed.
Her hesitant gaze was fixed on him.
Leo welcomed her without the slightest hesitation.
“Your Majesty….”
“Just lie down.”
He gently grabbed Seras’s wrist and pulled her.
A gentle gesture, treating her as a woman, not a knight.
“Kya, kyaa!?”
Seras also let out an awkward shriek and lay down.
If she wanted to, she could easily shake off this hand.
But she had no intention of doing so.
And so, the two men and women lay on the bed,
-Slither.
‘H, he even covered me with a blanket…!! Leo and I are on the bed, alone under the blanket!!’
A thin cloth enveloped them.
So that no one could see what would happen from now on.
As if he had been waiting, Leo hugged her.
“I’m sorry. Were you very scared?”
“Ah, no… Your Majesty….”
“Just for today, call me Leo, not Your Majesty. Like the old days.”
“…U, un. Leo.”
Their flesh pressed against each other.
They were so close that they could hear each other’s heartbeats.
His hand, which usually felt a bit unreliable, felt very dependable today.
It slowly moved up her body.
His fingers passed over her bare arm and touched her back.
“But, Seras.”
“Heuh….”
‘I, I’m being hugged by Leo in just my underwear!!’
Her face flushed red at that, but…
-On the contrary, Leo became serious.
“If it’s you, who I’ve been with since childhood, you’ll know ‘without me saying’ how I feel.”
-Stroke, stroke.
“….?”
‘Suddenly ticklish?’
His fingers were stirring her back.
Unnecessarily complex and delicate movements.
It was almost a minute later that Seras realized what it meant.
“Y-Your Majesty. It tickles… Heuh!?”
‘Wait, this is runic script?’
What was being written on her back was the common language of the continent, runic script.
The sentence that Leo had been repeatedly writing since earlier was…
[There is a possibility of surveillance. Do not be alarmed, and let’s have a real conversation in writing.]
“……!!!!?”
‘Surveillance!?’
Didn’t that mean they were being watched right now?
Even in the bedchamber of the king, Leo.
Thanks to that, she regained her senses.
Long, slender fingers danced on Leo’s skin.
-Stroke, stroke.
[I’m sorry for being late to notice. Is it an ambush?]
[The risk of that is low, so don’t worry.]
[Then who is it?]
[There is a possibility that Teonar is watching.]
‘Damn it, to have to do this to Seras….’
Leo squeezed his eyes shut at that.
The reason he was doing this to Seras, whom he cherished, something that could cause a scandal.
It was because it was so… bleak.
‘He easily teleported to Valentia’s office. A place with much stricter security than ours.’
‘If teleportation is like that, surveillance must be doubly easy. Anywhere is in the palm of his hand.’
‘More than anything… when I reported it, he didn’t seem very surprised. Rather, he acted as if he knew and didn’t care.’
‘He already knew. About the Human Alliance. Probably from the moment I heard the proposal.’
‘Everywhere on the continent is under Teonar’s surveillance. It’s not an exaggeration to think that way.’
If it was Teonar, the Transparent Dragon, he could even monitor and eavesdrop on their conversations.
That was why he had brought Seras into the blanket.
He wanted to believe that even he couldn’t peek at what was covered by the blanket.
‘Maybe he can even see through this measly cloth….’
In fact, as he feared, this was a shallow trick that Teo could easily break through if he wanted to, but,
“Kuang~.”
‘I guess it’s better for me to lay the tracks for the railroad myself? I want to minimize intervention, but time is money, after all.’
The person in question was off guard, not even dreaming that Leo was doing this.
Inadvertently, he had caught him off guard.
No, wasn’t it right after a big victory in the first place?
It was only natural to be off guard.
Leo could never miss this opportunity.
[Teonar might be watching….]
[And Seras, never utter the words I’m about to tell you.]
[…..I understand. Give me your orders.]
[———From now on, Arkenia will devote all its efforts to uniting all of humanity to subjugate Teonar.]
He moved his fingers.
The reason for moving so secretly, betrayal.
It was to convey that to Seras.
Thanks to that, she was startled,
[Your Majesty?! Why would you.]
[Just listen quietly. This is something only we can do. The fate of humanity depends on us.]
Leo continued to write in runic script.
To persuade her of the reason he was betraying him.
The reason was that Teo was…
‘Too strong.’
[Imagine a 10th-circle Explosion Magic. A magic with the power to completely destroy the capital if it goes off.]
[This magic can be used indefinitely. Surely, even the Kaiser Empire wouldn’t dare to oppose it.]
[Now, give this magic wings and a tail. Give it intelligence beyond measure.]
[That is Teonar.]
Teo’s strength was alien.
Even compared to the dragons recorded in history, he was unmatched, an existence capable of destroying an entire nation alone.
[Of course, he is friendly now. His intention to coexist with humanity must also be genuine.]
[But… how long do you think that will last?]
[What if a second or third Mark appears? What if that experience is repeated dozens or hundreds of times? Will his intentions still be the same?]
[It would be difficult. He lives in a different time than we do.]
[Even if such a person appears only once every ten years, it would feel like an incident happening every month to him.]
[Would he still try to coexist with humanity after experiencing such things? Someday, his mind will change.]
[Not right now, and maybe not until I die….]
[Eventually, Teonar will change. There will come a moment when he wants to exterminate the entire human race.]
[That will be the day humanity goes extinct, the day we receive the karma for what we did to the dragons.]
Even he will change someday.
Leo was convinced of that.
[Of course, if we stay still, nothing will happen to us. We will enjoy a peaceful reign until we die.]
[But that is simply closing our eyes to the future of the kingdom. It’s no different from passing on an Explosion Magic, a bomb, to our children and grandchildren.]
[As the King of Arkenia, I cannot do that.]
That was why Arkenia had to kill Teo.
Not because he was a different race…
But simply because he was too strong.
Hearing that far, a scene suddenly flashed before Seras’s eyes.
It was the smiling face of a woman with green hair and narrow eyes.
[—They are ‘pests’ that cannot coexist with us and must be exterminated.]
…Aurelia. With someone like that as a vassal, it will surely happen someday.’
Aurelia, who saw humans as insects.
Even his closest aide was already like that…
How could a ruler who sees and experiences so much not be swayed?
In her opinion, Leo’s opinion was valid.
In the end, Teonar’s mind was bound to change.
Feeling somehow scared, she hugged his body tightly.
[But it’s impossible. With our current national power, it’s impossible to stand against Millenia.]
[Rather, now is the perfect time.]
[…Your Majesty?]
[Dragons are a race that grows stronger with time. When he is still a hatchling is the greatest opportunity to defeat him.]
[But.]
[In addition, think about Millenia’s technology. One year for us is like ten years for them. Time is not on our side!]
His fingers tightened.
He wanted to give up right now.
But he could not let go of his duty as king.
To protect the future of the kingdom, of humanity.
[Fortunately, we also have a way. The holy relics, the divine weapons bestowed by the Main God for humans.]
[Arkenia’s holy relics are woefully inadequate! The Sword of Truth means nothing in the face of that explosion.]
[Humanity is not just us! There’s Valentia, Normare, Belarus, Selicia… even the Kaiser Empire.]
[…The Kaiser Empire!!?]
[We will unite them. Just like the heroes of old, we will unite and rise again.]
[There’s no way that’s possible.]
[It is possible. Because we are not any nation, but the weakest nation on the continent! Because we are an ally that Teonar will not suspect at all!!]
In the darkness, his blue eyes shone brightly.
[Only the weakest Arkenia can defeat the strongest dragon!!]
* * *
“I’m sorry, Seras. I didn’t intend to keep you here so late.”
“…It’s okay, Leo.”
An awkward atmosphere flowed between the two.
It looked like they had just finished engaging in royal duties.
‘I need to start by enlisting trustworthy people within the kingdom right away. I’ll be working overtime every day from today.’
Of course, that was just acting.
Leo was still thinking about his next move.
Because he was searching for a way to kill his friend…
“Then go back now. Thank you.”
“…Leo.”
“Don’t worry. Of course, I won’t tell anyone about what happened today.”
That was why he sent Seras out.
From now on, he had to stay up all night and think about strategies, so it was only natural.
She also understood his intentions and immediately left the room…
-Poke, poke.
“Hmm? Seras?”

“W-Well, I thought you might be feeling complicated and stuff all alone? I could talk with you all night?”
‘Idiot. He’s going to brood all by himself again….’
Instead of leaving the room, she committed the impudent act of pulling on his clothes.
It was something only his childhood friend could do.
“Alright. Come, lie down, Seras.”
“…♡”
[I’m asking you, a military expert. To attack and destroy that facility called the factory….]
[I’ll have to hear what Bella-nim has to say, but if it’s magic, we can do something about it….]
The two stayed up all night.
Thanks to that, Leo’s heart became a little lighter.
The warmth she gave him became his driving force.
“Oh, the envoy of Valentia! I’ve been waiting for you!”
“Your Majesty? Why so.”
-Embrace.
[There’s a possibility we’re being watched. Don’t show any agitation, and let’s communicate through writing.]
“…!!!?”
After that day, he moved busily.
His efforts were beyond description…
But there was no need to express them.
After a full three years had passed, he had achieved most of his goals.
-Hwaaak.
“I will cooperate. Monarch of Archenia.”
“…Thank you. Last Dragon Slayer, Raphael von Nordtrand.”
Finally, he had joined forces with the hero of the strongest nation in humanity, the Kaiser Empire.
This showed how outstanding his diplomatic skills were, and how much they had advanced.
The Kaiser Empire was a superpower that single-handedly withstood the alliance of two great powers.
It was a nation that even the monarchs he had already persuaded had disliked.
To have accomplished this in just three years was truly worthy of being called a miracle.
However…
“Lady Seras! This Hangeul is amazing!!”
“I hated reading runes so I never even looked at books, but if I had known it was this fun, I would have learned it sooner!”
“I want to go to the Millennia Arena once. To be able to fight mythical monsters without any injuries, and to be showered with all kinds of gold, silver, and jewels, and applause! It’s like a knight’s dream!”
“….”
‘Leo, if you’re going to do it, hurry up!! At this rate, we won’t even be able to fight!!’
-During those three years, Millennia had blanketed the continent with Hangeul.
