Inside the office, I ran my pen over the parchment for the formal document.

　The official language of a nobleman, the official typeface, and the official signature.
　It was all of those things, and it was a valid document.

　Finally, he checked it all over from head to ass and muttered, "Good.

　Then there was a knock at the door.

'Who's there?'
It's me.
Sister?

　The door opened and my sister appeared.
　She was smiling and holding an envelope in both hands.

'Look, brother father,'
I can't tell you how many times I have to tell you to stop calling me that.
It was given to me.
What is that?
'Here's a letter from Erika, who suddenly appeared in front of me.
"Huh?

　I popped up nicely enough to hear the onomatopoeia, "Pocanne,

　My sister opened the envelope, took out the inside and read it out to me.
　It was a sentence I'd heard before.
　Every word is the same sentence as the one Lina had received.

"What should I do, brother dad, I'm going to be turned into my brother dad's wife!

　After reading it, my sister said that in a theatrical tone.
　She grinned in addition.

　I got up and walked over to my sister and took the whole envelope away from her.

'Oh,'
Yeah!

　As it is, I open the window and toss it out into the sky.
　If that wasn't enough, you thrust your hands out alternately toward the letter that's about to become a star.

'Awwww!'

　And then he fired a series of magic bullets.
　Obviously overkill, the letter disappeared in the air without a trace.

''Oh.''

　The sister saw this and clapped her hands in a small way.

'You'll do it, Hermes. But you mustn't do that.
I don't think my sister should take this letter.
No, no, that's not how it works.
Yeah?
No, the hot one.
"Huh?

　What do you mean?　I look at my sister.

''According to what the First Lady heard from her ancestors, an attack that shoots magic power in rapid succession without trajectory is called 'losing frugality.'''
I don't understand. What's a wobble?
I believe they call it the War of Promised Defeat.
You leave out a lot of nonsense in the first generation.

　I sighed and went back to my chair again.

　I check my finished writing one last time and try to seal it.

'What have you been writing, Hermes?'
This one?　It's a document that cedes the viceroyalty.
What?
I'm leaving the governorship to your sister and I'm going on a journey.
Yeah!

　She snatched it out of my hand and threw it out the window with a dynamic form.
　The weighty parchment text quickly became a star.

'Oh, I've tried to write. 'What are you doing, sister?'
'That's the line over here. What are you doing here, Hermes?
No, because if we don't, there's going to be a big fight.　I'm the cause, and if I'm not here, that can be avoided, right?
Hermes, you're tired.
I don't know.
His Majesty would never approve on such grounds.
Ugh....

　Maybe you're right.
　His Majesty the King would never approve of my hiding for this reason.
　Rather--

''We might formally start a war with Calamba for the reason that we got rid of Hermes, don't you think?
Ugh....

　That was something I could normally imagine the scene.
　Normally I would just kick it off with a "nonsense", but that His Majesty the King.

　It really wouldn't be surprising if he did, and the events that have transpired so far have made me think so.

'Yes, Hermes, let's go on a trip. That hot spring you mentioned might be a good place to go.
Travel?
Take a hot bath and refresh yourself.
That's why.
Hermes, you're tired.

　She uttered the same line twice.

'The usual Hermes would have known at once that His Majesty would not see fit to give up the viceroyalty for such a thing. Before writing such a troublesome thing.
Yeah ... maybe.

　A document in effect on parchment.
　Formal wording, formal typeface, formal signature.

　It all smelled like a hassle.
　My sister was right, if it were me normally, I would have thought it would be cumbersome or impossible before I did it.

'Hermes has poor judgment now. It would be good to get away from here for a bit and take a hot spring or something to refresh yourself.
But what if I leave now and we're invaded during that time?
Hermes is tired after all. Without Hermes, the Demon King can't move. He poses no threat whatsoever.
Yeah, sure.

　Kaori is the strongest creature on earth, an existence that is normally feared.
　But Kaori has a chain attached to her, a chain that was put on her by the previous demon king that says she can only fight opponents that are equal to or better than her.
　If I were to disappear from here, it is true that Kaori will be unable to do anything.

　When my sister pointed this out to me, I groaned involuntarily.

'Yes, but still, Erika is here. Her goal is to bring this place down to earth. Even if Kaori can't move, she can move.
That's exactly what I'm talking about. It only takes one billboard.
A sign?

　She smiled silently and approached the office desk, running a pen across the paper in a breezy manner.

'We can build this on the route we expect Erica-chan to march on.
What is it?　'I'd hate you if you attacked me when I wasn't home'... is that what you want?
Now Erica, more than anything else, she should be afraid that Hermes will hate her.
Is that so?
'It is. That's the maiden's heart, your sister assures me.

　My sister said, and she literally burst out of her chest.
　I don't know what it was, but it was a tremendous confidence.
　It was convincing, as if the words came from actual experience.

'So, if you keep this up, you'll be fine without Hermes.
Well no, it's still bad.
What's that?
Setting this up is like admitting to the world that Erica likes me.
With letters like that already circulating?
Ugh.

　I moan again.
　'You're right, sister, you're right.

'Still, you can't just admit it on my end. If I do that, it really does become an established fact.
I see, and you have a point.
Right?
Then just make sure that only Erica can understand.
''Well I see, so we can just make sure that only Erica can see the words on the stand, right?''
What?
What?

　What is it?　Now "What? Ha.
　Did I say something weird?

　Her sister glanced out the window in surprise.
　Outside the window ... what do you see?

'No, it's nothing. Yes, that would be better.
Okay then, that disguise spell Erica was using. I'll arrange the thing--

　I took a new piece of paper and ran my pen over it.
　After I finished the sentence, I cast a spell and showed it to my sister.

'What do you think, sis?'
"'Only your sister can see'...?
He wrote on the side of it, too.
I don't see him.
Okay.
What did you draw, by the way?
Only Erica can see him.
I see.

　Application of magic in disguise.
　You can't just be able to see by the amount of power you have, you can see by the wavelength of the person's power.

　If it's just the strength of your power, maybe you can break it.
　But if it's magic that designates an opponent, no one else can see it.

　I've arranged for a billboard.
　I wrote a letter (...) to Erica on the bill, as advised by my sister, and cast a spell on it so that only she could see it.



　The billboard was effective.
　When Erica saw it, the Karamba army led by Erica immediately turned back.

　And - the people of the Cano territory honored me (,,,,).

　The fact that with a single stand-up card with nothing written on it, I was able to repel the army led directly by Queen Karamba became popular.
　The people, who didn't know anything about it, began to speculate that the billboard was a sign that something was being done to destroy their army.

　When I found out about it later, I got my head around it, but my sister said something to me.

'You were really tired, Hermes. You should have just sent a normal letter.

　He looked at the poor guy as if he were looking at him.
