Though he'd thought to quickly build it alone, by King Rashion's design, Celeste's mansion construction became a grand royal capital event—a royal viewing ceremony.

  After the main white mansion, he materialized several buildings that would become essentially the royal family's villa and attached structures, and the demonstration closed successfully. The gallery, initially shocked, finally raised unstinting voices of admiration at the buildings rising one after another.

  Having tossed the shovel and cardboard that finished their role into a gate, Celeste retrieved his recording smartphone. Exiting through the iron fence's main gate with the Nairan couple, he returned to where the King and others waited and bowed deeply.

  "Your Majesty. With your great consideration, I have safely completed the mansion's establishment."

  "Mm, well done.

  No... this feels strange to say.

  I wondered what kind of construction you'd show me, but to surprise me this much."

  "Your words are too kind."

  Even King Rashion felt odd offering words of appreciation himself, formal exchange though it was.

  "So?

  When will you invite me?"

  "My, Your Majesty is quite eager.

  Having just built the structure, the interior furniture and facilities aren't yet arranged.

  I hope you'll grant me some preparation time."

  As Celeste smiled wryly internally at King Rashion begging to tour the mansion, Queen Isha threw him a lifeline.

  "Royal Father is right, Your Majesty.

  Moreover, with such a grand mansion, Royal Father alone cannot manage it all.

  Arranging and preparing servants will also be necessary..."

  "As expected, Your Majesty the Queen knows well."

  "Overseeing all palace life is also the Queen's duty.

  I must understand at least that much.

  Ah, right... may I handle selecting this mansion's servants?"

  "Eh, Your Majesty yourself?"

  Of course, having just come to this world, Celeste understood nothing about circumstances outside the royal palace. Moreover, avoiding scrutiny of the business content he was about to start in partnership with the royal family was his honest feeling.

  "To prevent unwanted insects from attaching to you, I should search for you.

  Well, though I say search, I'll just utilize connections and make final judgments."

  The Queen speaking this far meant commanding 'obey without refusal.'

  And Celeste could predict from her—Isha's—personality that she'd probably already finished roughly selecting personnel, so while feigning 'reluctance,' he decided to follow Isha's words.

  "I'm truly grateful...

  I humbly accept Your Majesty the Queen's kindness."

  "I'm also looking forward to this mansion's unveiling."

  "Pardon?"

  As Celeste tilted his head feeling he'd just heard something ominous, the Prime Minister standing behind the King quietly stepped forward, volunteering as explainer.

  "My my, Regis Celeste seems not to know yet.

  As the kingdom's custom, upper nobles of Comis rank or higher newly granted mansions in the royal capital hold unveiling parties for those mansions.

  For parties, custom is sending invitations to nearly all nobles in the capital at that time, headed by His Majesty and Her Majesty.

  If you discover this tale on Amazon, be aware that it has been unlawfully taken from Royal Road. Please report it.

  Well, of course there are personal closeness and distance, so strictly speaking not literally everyone... but in your case, everyone should be eagerly awaiting invitations."

  Oh no.

  Celeste screamed internally.

  He'd also thought he should at least greet neighbors about moving in.

  So when he'd found this was the only vacant lot suitable for building, and consequently learned the only neighbor was that Military Affairs Minister, he'd been relieved thinking neighborhood relations could be handled casually.

  Yet.

  'Unveiling party? What's that?

  I'm not a party person—I can't do that!'

  Seeing Celeste in a mood to hold his head with such thoughts, eyes darting about, the King said with a grin:

  "You're thinking something troublesome again...

  Don't worry, Royal Father.

  In your case, just showing the mansion's interior should suffice."

  "Y-yes..."

  Though the King said so, it wouldn't work that way.

  He'd never directly experienced the noble world, but had some indirect experience through novels, manga, dramas, films.

  A world where prestige mattered most. Losing face here would naturally narrow his own position going forward, and poorly handled, would smear the royal family's face.

  That alone must be avoided.

  "Understood.

  This Celeste, though inadequate, shall prepare a splendid unveiling party to not shame Your Majesty's expectations."

  'Though the expenses are on you, Rashion!'

  The Prime Minister listening to their conversation was also holding his head internally.

  Celeste underestimated his own value and abilities.

  Moreover, Felideria's parties normally meant light refreshments while exchanging conversation—in Earth terms, reception party format was common.

  Honestly, he didn't know what Celeste was thinking, but felt just preparing large quantities of those 'forbidden treats' served at that ministerial meeting day would be more than sufficient.

  ...Moreover, if those honey treats came out, the Ursort folk would try fawning on him.

  Even that Justice Minister had knelt before him.

  'Don't try hard! Just do it casually!'

  Unaware of such Prime Ministerial worries, the King proceeded to the next topic.

  "So, until this mansion has servants and security personnel, we'll need guards stationed, right? So miscreants can't enter while Royal Father is away.

  Dispatching several from the castle guard should suffice, but I'd like to ask someone to care for them.

  Military Affairs Minister, as neighborly friendship, won't you help?

  It's a good opportunity—I hope you two become good neighbors, friends.

  And until guard forces arrive, won't you lend your security?"

  "Yes. I humbly accept."

  "I'm grateful, Marc Mengen.

  Please take care of it. I'll send good liquor later..."

  "No, it's a royal command."

  Stating curtly and turning on his heel to return to his mansion, Mengen slightly irritated Celeste.

  'No need to say it so bluntly?'

  "Then, shall we return to the royal castle?

  Royal Father, what of you?"

  "Yes. I have mansion cleanup and such remaining.

  I'll visit the palace later."

  "Understood.

  Then everyone, let's go."

  While everyone present bowed, the King departed toward the royal castle with the attendants he'd brought.

  "Now, Rashion has returned..."

  Muttering this, Celeste loudly addressed the gallery:

  "Everyone, I sincerely apologize for today's disturbance.

  I look forward to meeting you all at the unveiling party.

  Now, I have cleanup, so please excuse me."

  Celeste left the gallery with a greeting and light bow, opened the iron fence's main gate and entered. Watching him walk toward the mansion through the fence, the noble district gallery wondered what kind of party that otherworlder would show them.

  "So, I'd like to ask Madame for that role."

  "My, can such a shabby old woman fulfill such a great duty?"

  In the royal castle, the Queen's salon, Queen Isha and one elderly lady conversed.

  "My, you jest.

  If Lady Biala is a shabby old woman, there wouldn't be a single noblewoman in this country?"

  "Your words are too kind, but you overestimate me."

  Apparently the elderly lady wasn't very inclined even hearing the Queen's proposal.

  "Our relationship...

  No, precisely because you were His Majesty's wet nurse, I wish to ask.

  You know what kind of person he is, don't you, Lady?"

  After taking a sip of tea, the lady paused briefly before responding.

  "Yes.

  His Majesty, Her Majesty, His Highness the King's Brother, the Princess...

  The father in previous lives of all current royal family members, possessing various mysterious powers.

  Though a hard-to-believe story, I confirmed it directly with these eyes the other day."

  "Oh? You did?"

  "Yes.

  Someone who wielded most mysterious powers as if nothing.

  Though his bearing lacks some refinement, his speech is very polite, and I perceived him as someone who'd received considerable education even if not noble."

  "I see.

  Precisely for that problem you just mentioned, I want you to go to that mansion.

  Someone who's our royal family's precious father, yet might become great strength for this country.

  However, that person..."

  "You mean he doesn't know the noble world?"

  "That's right. Of course, as you said, being someone with high education standards, he won't easily show flaws, but still I think someone to teach him noble refinement is necessary.

  Moreover, that mansion has no wife.

  Though I don't think he has such inclinations, if despicable sorts appear trying to exploit that gap..."

  "My my, is Your Majesty trying to matchmake me with that person?"

  "Oh, goodness. Certainly not."

  The two who'd continued elegant conversation burst out laughing.

  "I have a favor to ask, though it may be a burden. I wish for you to be more than just a teacher and housekeeper; I want you to govern that mansion as its 'Chatelaine,' serving as a proxy for the lady of the house.”

  "My my, that sounds like laborious duty for this old body."

  "But there's no one more suitable than you.

  How reassuring if you—reigning at society's pinnacle—attended that person."

  Mēre Biala.

  Former head lady of the great noble Comis Biala house, currently having transferred the head position to her son and wife and living leisurely, the queen of society in bygone days (of course, metaphorically, being a monarchic state), and a woman standing at the highest position among this country's noblewomen, still reigning at the pinnacle.

  This Persian Felinoid elderly lady with a stubborn, strong-willed face was about to summon a storm to Celeste's white mansion.

  "ACHOO!

  ...Is it the dust...?"
