I'm going to boil down the plan to assassinate the second prince in my room, and since I'm going to meet with Nevan, the Duke of Lomarng's family, I want to have a meaningful conversation with him.
　In hand is the second prince's schedule handed to me by Duke Romalung.
　........I originally thought that if I could kill it, it would only be at a certain time, but to reaffirm that, I reviewed it again.

''It's the Founding Festival, after all. That's the only place you can kill.

The Founding Festival is an annual festival.
　Due to the appearance of the demon tribe, there was a possibility that they would refrain from holding it this year, but it will be held successfully.
　There, the prince will also go outside the castle and participate in the parade.

The tricky part about killing the prince is that he has no other option but to die of illness or accidental death.
　The opponent is the prince, and if he is assassinated, he must find out who the ringleader is, for the prestige of the country.
　I won't expose the dumbass who will be identified just because he was investigated, but if the culprit is not found, the country will prepare a scapegoat to protect its prestige.
　........Honestly, that's not a good way to wake up, and I don't know what kind of a jumping off point it would be. The card that the prince was assassinated can be abused by various forces in various ways.
　So, it's only an accident or death by illness for the prince. The accident is also the only way to go after it, as the potential cause of the accident and the guards are collectively guilty of a felony, so the only way to go after it is to die of illness.
　If it's an illness and death at this time, there's no need to create a culprit. In addition, it's enough of a threat to Countess Grunfeldt and her cronies.

''If they think it's poison, they're out for a shot. That's quite tricky.''

I look at the needle in my hand.
　It's one of the dark tools and is coated with poison. It's a poison that produces interesting symptoms, and no amount of research on this side of the world will determine that it's a disease.

The problem is the timing of typing it in.
　If you don't have a disease and death binding, that's just one shot if you snipe it, but if you're going to strike this needle, you need to get close.

If the person you're dealing with isn't royalty, then you can sneak into their bedroom and attack the sleeper.
　But that's not possible in a royal castle.
　On the floor where the royals live, there are wards that are activated the moment anyone other than the royals and their guards enter. It is a divine device that detects the wavelength of the soul. It's impossible for me to deceive a tool made by an inhuman being. When I step into it, the warding is activated no matter what I do or how I do it.

When the warding is activated, I'm confident that I can kill the prince, hide, get away with it, and escape. But the warding was activated. That means that when the intruder's presence is apparent, he is determined to have been assassinated, whether he dies of illness or not.
　I'm confident that I can outwit the guards if I can get them to lift the wards through subterfuge, but there's no way they can give me the support to leave such a trail.

That's why I'm aiming for the Founding Festival parade, where the prince will be outside.

''Well, it looks like Duke Romalung wants you to kill him at Meena's party. No, this is testing me.

The schedule also includes participation in a party hosted by the Countess of Grunfeld, the public face of the snake demon race, Meena. It's also crafted to be eye-catching in its placement and typeface.

If it's determined to be an assassination, it's over. There is one exception to that rule.
　To put the blame on the person who caged the second prince.
　For example, if the second prince is going to be killed at a party she hosted, she can put Meena in the role of scapegoat.
　Simultaneous elimination of the broken puppet and the mastermind. A more efficient method. ........unless the other party is Meena.

Normally, if the Countess of Grunfeldt suffers the crime of killing the prince, those who were caged by her would leave to avoid collateral damage.

However, the second prince was so broken that he had to destroy it. With that in mind, there was even a chance that he might go upside down and run away rather than leave.
　Above all, I don't know what that demon tribe will do. What kind of catastrophe will be caused if wearing Countess Granfeldt's skin becomes a hassle.......
　This must be testing me. I dare to make them pay attention to me, but I can't seem to aim for that.

'That's interesting,'

I will look at the schedule of the second prince, but the only thing I'm still aiming for is the Founding Festival.
　That Founding Festival also has to be heavily guarded, and it's not even allowed to be suspected.
　It's been a long time since I've felt my blood boil as an assassin.
　........A case that even a top-notch assassin would find impossible. That's why it burns.

◇

The next morning, a letter was sent to me by courier pigeon.
　It was Nevan's reply to the request for an interview that I had written the other day.

"To come this afternoon?

You are very impatient.
　The Duchess is busy. I'm sure she's pushed her schedule pretty hard.
　That's how important she considers us.

"Ugh, Roug, you're scintillating!
Time to get up. It's almost time for breakfast.

The light coming through the window wakes Dia up, and she wakes up on her upper body and rubs her eyes. She's not wearing anything and her lovely breasts are revealed.

'It's that time already. Roug didn't let me go until late yesterday, so I haven't gotten much sleep.'
It was probably Dia who wouldn't let me go.
I knew you didn't understand women's mindset yet. In times like these, you have to build up a girl.

Dia slips out of the covers and takes a change of clothes out of the closet.

'This closet, you're going to get in trouble if you show it to anyone else. They'll either suspect me of having a taste for cross-dressing or call me a harem bastard.
Well, yeah.

The closet holds Dear and Tart's clothes and underwear.
　A lot of Dia's clothes are there because that's what lovers do to each other. A while ago, Dia didn't want to do it in the mansion because she was embarrassed to do it, but before long, she stopped caring.

And because Tart was traumatized by the loss of his family when he was very young, and sometimes he sleeps with them when he's lonely and can't help himself. My room is closer to the kitchen, and it's a hassle to go back to my room every time to change.
　As Dia was finishing dressing, I heard a knock at the door.

'Roug-sama, Dear-sama, dinner is ready!

Tart's cheerful voice echoes.
　Hearing this, I know that another day has begun.

◇

After breakfast, we set off in a carriage.
　It's not just a horse, it's a horse that has been slightly modified through a treatment using the magical powers passed down in Touahade, and it's no longer a monster.
　After a lot of experimentation, it has finally become able to operate stably.
　However, its temperament is rough and its speed makes it difficult to control, so its use is limited.
　A certain nobleman obtained overwhelming speed in the direction of using demons, but there is also this approach.

''Hey, after all this time, who are you going to meet?''
Oh, this is Nevan, daughter of the Duke of Lomarng.
Wow, I thought maybe you were the princess of brilliance.
What? You knew?
Of course. Because the name echoed all the way to the Kingdom of Soonger.

Nevan is also a celebrity.
　He even has his overwhelming good looks, an extremely rare light magic user, and even a great achievement.

''How could someone like that listen to you?''
''You haven't told me yet. The dukes of Romalung are superiors to the Touahardes. They're the ones who decide whether the royal family's request is in the national interest, and how to make our killing work in politics. This, of course, is top secret.

The back and front must not be connected.
　If the connection is not known, in the unlikely event that Touahade's assassination is exposed, they can simply cut Touahade off.
　However, if the connection is known, when it is exposed, it will be cumulative to the Romalung duke family and even the royal family above them.
　That's why, until now, the Romalung and Touahade had ostensibly had no involvement whatsoever.

''That's it, is it safe to enter the territory with a carriage in open daylight like this?
It's okay. I'm here today as a holy knight. And it's all in the form of a royal request. It's a reasonable request. I can't believe this is taking half a day to root around.

For a mere baronet to join a duke's family would arouse suspicion, but not if he was a holy knight.

''I'm getting nervous about meeting the Princess of Splendor. What is she like? Is she as beautiful as they say she is?''
She was very beautiful.
Why the tart... I remember the tea party at the castle, there was a princess and her son, the Duke of Romalung and his son.

Deere sulks a bit.
　Dia could not participate in that place due to the request of the other party.
　She still holds a little bit of root in her heart that she couldn't see the garden that the Alwan Kingdom is proud of as the most beautiful in the world.
　And so, we finally arrived at the duke's domain of Romalung.
　We passed large farms, large ranches, and orchards, and finally approached our destination after passing a large city that was no less than Murteau.
　It has been a long time since we entered the territory. The reason is simple: it's too vast a territory.

It's really just one territory.
It's all there.
The ordinary nobleman prepares, polishes and colors each territory with weapons. They're good at agriculture and exporting food, or a commercial city that focuses on business, or an industrial city that digs mines and processes them. But in the case of the Dukedom of Romarnung, there is no such bias. The farmland, ranch, industry, commerce, and everything else is top-notch. That's why the foul-mouthed nobles sarcastically call the Roemarung territory. The Romalung Empire. Everything has been completed in one territory. The Kingdom of Arvan, the most powerful aristocracy.

He continued to breed and educate for hundreds of years to create the ultimate human being. To do this, they continued to greedily gather the best blood and teachers from all over the world.
　The result has been a brilliant people, wisdom gathered from all over the world, and a network that stretches in every direction.
　The synergistic effect of these factors has been created. In addition, superior people compete with each other and grow more.
　The result is a prosperity that is even referred to as the Romalung Empire.

........The name of the Romalung Empire is ironic, but at the same time, it is a word that comes from fear.
　Every aristocrat is afraid of the Romarnung. It is even said that even if the Kingdom of Arvan is split in two, and it becomes the Lomarung and the rest, the Lomarung will win.
　This is the first time I've seen the Lomarung territory, but at a glance, I even thought that this was the point of human attainment at the moment.
　And finally, we arrived at our destination.
　Tart and Dia leaned out of the carriage with their eyes wide open, and I was gobsmacked. And I'm gobsmacked too.

''Wow, it's amazing. It's a very, very magnificent castle.
'It's amazing, but it's too awesome!　What, rogue, you can't do this!　Wouldn't he be offended by your building a better castle than the one in King's Landing?　If you do something like this in Soonger, they'll call you irreverent and crush you.

It's a castle. It's the most beautiful, majestic and, above all, functional castle we've ever seen.
　Even the beautiful royal castle pales in comparison.

"This castle was built last year. ─ This castle was built last year in the name of the best theoretical castle that could be built with the most advanced technology. In terms of size and performance, it is incomparable to the historic castle in the royal city. A nobleman doesn't get credit for building a better castle than the king. But they're allowed to do so because he's the Duke of Romalung. He has done more courtesy and service to the king than any other nobleman.

That one was a construction, though it was more a matter of construction, and that the royals and other nobles didn't have enough power to pick a fight with the Romalungs.

'You know what, Lug. It's just a matter of if. If the Romalungs had their way, would they take over the country?
I guess they could have done it any time before I was born.

That's the truth about this country.
　The only reason why the Kingdom of Arvan can remain the Kingdom of Arvan is because the Romalungs are loyal to the king.
　Because he is so powerful, he can make all the other nobles stare at him.
　Despite having this much power, Romalung was using his power for the good of the country.

''Well, let's go. It's almost time for the appointment.''

The castle is surrounded by a huge lake with a magnificent bridge across it. The clear lake had many fish swimming in it, many of them edible, said to be delicious. This is probably to protect the castle and at the same time it's an aquaculture farm, which seems to be a Romalung for efficiency.

I brace myself.

If you're not careful, you'll be eaten in a flash.
