“Ah, I tried various tests, and the invisibility state varies depending on how much power is infused. Simply put, it divides into two stages.”

“…Really?”

“In stage 1, physical force remains active, but in stage 2, he can’t use power. So I think I’ll keep it in stage 2 during dates.”

“……”

This part was certainly surprising.

Though Saena had designed it, since she wasn’t the power’s owner, she couldn’t experiment directly and hadn’t known this fact.

“Even if he can’t lick, he can still watch… are you okay with that?”

Having heard explanations about Erenhorn having something like voyeuristic tendencies, Saena asked with doubt.

“When I make him invisible, he happily disappears!”

“…Where to?”

“I don’t know?”

“……”

Though they expected Erenhorn would be dissatisfied that Lucas controlled whether he could exert physical force during invisibility, he was surprisingly very satisfied with the current situation.

Even Lucas hadn’t thought he could chase away(?) Erenhorn so easily.

Previously, whenever he was with a woman, Erenhorn would rush over from somewhere and interfere.

But now, just making him invisible sent him excitedly off somewhere.

Though invisible, since Lucas was his master, he could sense his presence and easily tell that he wasn’t nearby.

If he concentrated sensitively, he could feel him busily moving around somewhere far away, but he didn’t try to determine exactly where.

He was certain that knowing would only cause headaches.

And while Erenhorn disappearing somewhere was a very satisfactory result, it would have been fine even if Erenhorn hadn’t gone away.

Even if he watched from nearby, it was manageable if he couldn’t interfere.

In truth, his s*xual modesty, which they thought was extremely sensitive, could be compromised at this level.

Though Lucas himself hadn’t known this fact, that’s how it was anyway.

So why bother researching more?

What if further research made the situation worse than this?

“Anyway, I’m truly satisfied. You’ve worked so hard all this time, Duchess.”

“……”

“How should I repay this favor? Please think deeply about compensation and take as much as possible. I’ll accommodate anything within my power.”

He listed several examples, which were exceptionally generous.

He smiled continuously even while talking about giving compensation, showing how satisfied he was.

If the client is satisfied even with a failed product, perhaps that’s good enough…

Though slightly confused, she decided to think that what’s good is good.

Though some unease remained about Erenhorn’s whereabouts during his invisibility, like Duke Aberdeen, Saena didn’t want to dig deeper.

Thus concluded the research on controlling Erenhorn.

After several generations passed and much time flowed, the Aberdeen family’s Guardian Spirit’s modifier changed.

From the Phantasmal Unicorn <Erenhorn> to the Silver Screen Unicorn <Erenhorn>.

Why did such a change occur?

Let’s deliberately refrain from trying to know deeply.

Also, the Celtic marquis family didn’t disappear but continued to remain, becoming famous for their jewel crafting techniques based on skilled Arlesian.

This was something that would happen in the quite distant future that couldn’t be known immediately.

* * *

Being born as a Guardian Spirit meant being born as a spirit.

That also meant being different from humans.

Humans, who go through brief periods of birth and death, often burned through their lives because they were short, and sometimes used all their strength to achieve something during that brief time.

In contrast, spirits are born with everything. This means all their tendencies and abilities are determined at birth.

They don’t strive to gain more than what they already have or try to change anything.

Just that much that each possesses at birth. They use that much ability and live with that much power.

— ……!

In his spirit life(?) where everything was so natural that he had no particular complaints, one day, Erenhorn had a shocking experience.

He met a Guardian Spirit in human form!

—Purr?

‘How can this be! I’m so envious!’

Though he didn’t know why he was envious, he was tremendously so.

No, actually he did know.

If one had a human form, wouldn’t they be able to do so much more(?!)

Erenhorn thought it was truly unfair and nonsensical that someone like that who didn’t even seem to need(?) a human form could take human form.

Somehow he couldn’t stop huffing.

I want a human form too! I want to know how!

Looking around briefly, he noticed that the human-form Guardian Spirit had a master with some strange abilities.

A human who could handle Arlesian well, like those who lived in this empire during the time when there were many Guardian Spirit friends.

So that’s the woman who recently succeeded in making a Covenant? How did she make the Covenant to achieve human form? I want to know! I really want to know! I sincerely want to know!

Though to others it would just sound like “Purr! Purrrr!”, for Erenhorn it was sincere curiosity and sincere dissatisfaction.

And soon he learned. That woman had started some research for Erenhorn and his master.

‘Can I have a human form too!’

Though no one had ever told Erenhorn that the research was about human form, for some reason, he thought so.

He felt too excited and expectant.

While anxiously waiting to see when results would come, one day he saw the woman shaking her head no!

Was she saying she wouldn’t do the research? Or that she couldn’t? That it was too difficult?

Whatever it was, head-shaking in human customs wasn’t good.

Moreover, lately he had been restraining even the behaviors his master disliked (though he didn’t understand why his master disliked them) and waiting quietly, yet he betrayed him like this!

So when he secretly listened in, there was talk about Erenhorn’s power, jewel attributes, how pink diamonds were good but unavailable…

In the end, the negative expression was correct.

One thing stuck in Erenhorn’s mind.

‘No pink diamonds?! Big ones?!’

Erenhorn immediately headed outside. He had to find pink diamonds to give her.

Who usually has jewels? Women wear them a lot!

Where are there many women? Party venues!

Party venues? They’re noisy!

Having found his answer through self-questioning, Erenhorn searched the noble mansions in the imperial capital for noisy places.

Pink, pink, pink diamond.

Pink, pink, pink diamond!

Though he was a unicorn, he earnestly scanned women’s necks and ears with hawk eyes like Halcon’s.

Usually when he scanned women’s necks and ears it was for other purposes(?), but now he looked for just one thing.

Whether there were jewels or not, and if there were, what kind.

However, as the human-form Guardian Spirit’s master had said, pink diamonds were too rare and hard to spot.

‘Ah! A pink diamond!’

But she said it needed to be big…

Even when he finally found one, it was just earrings about the size of a human’s pinky nail, around one carat, so it was useless.

No, I can’t give up!

Erenhorn persistently searched every party venue every night for pink diamonds and finally found one.

‘That! Pink! Necklace! Big! Mine!’

Erenhorn stared intently at the woman wearing the pink diamond necklace from a distance.

Erenhorn was a good unicorn and knew he shouldn’t attack humans to forcibly take the necklace. So he would wait patiently and ask for it.

As he stared at the woman like that, the smile gradually began to fade from the necklace owner’s face.

Occasionally she hesitated and looked around, rubbing her arms with her palms while shivering.

Why is she doing that? Ah! She must be cold!

Of course she’s cold wearing such a revealing dress! He thought humans were truly strange.

Eventually, the woman left the party venue with somewhat hurried steps and entered another building. As she went up to the upper floor, she shouted something to the guards.

“Watch carefully for any suspicious persons! And don’t let anyone up here!”

Is she going to put on clothes because she’s cold?

Erenhorn couldn’t understand why the woman was making such a fuss.

But this worked out well for Erenhorn. She had conveniently cleared out all the people, creating an optimal situation to approach her.

Erenhorn slipped into the mansion while concealing his presence and entered the room where the woman was.

The woman was just taking off her necklace. Seeing an open safe in front of her, she seemed about to put it in there.

Just before the necklace owner’s hand reached the safe, Erenhorn smoothly approached.

Since people would invariably scream when they turned around and saw him behind them, he activated an illusion and tapped the woman.

“What–! Ah…!”

The woman’s eyes became hazy.

—Will you give me that necklace?

Erenhorn conveyed his intention clearly. Under illusion, he could communicate with other humans too.

Of course, his master had told him never to do this unless in situations he permitted, but he thought this was an exception since his master would (?) want him to become human form too.

“The necklace? This? Ah, I can’t…”

—Give it to me. Okay?

“This is our family heirloom… Ah… Are you an angel?”

—…Huh? Then will you give it?

“If an angel asks…”

—That’s right. Quick, give it. You’re doing a good thing.

“Yesss…”

The woman handed the necklace to Erenhorn with dreamy eyes.

Having achieved his goal, Erenhorn disappeared without looking back, thinking she was a good woman.

Of course, he retracted his opinion about her being good the next day.

A thief! Why did she call him a thief when she gave it to him herself!

Thanks to that, his master hit him again! Waaah! Humans are so strange and his master is violent.

However, all of this was worth it. Though he got beaten tremendously by his master, heard lots of bad words, and went through various hardships, the end result was excellent.

Because that pink diamond returned to his master in a very beautiful form with very excellent functions.

To think it had such good functions!

—I! Became invisible! Ooh–! I can go anywhere and see anything!

With invisibility, there were so many places to go. Now he didn’t need to stay near his master.

He also liked that his master couldn’t hit him while he was invisible.

The nights that came every day soon became the unicorn’s favorite time.

Though he didn’t succeed in transforming into a human form, the unicorn’s life became very enriched after succeeding in invisibility.

Let’s not try to know specifically why it became enriched or what enriched it.

Also, let’s not try to know specifically where Erenhorn mainly started wandering around.

Anyway, that’s how it was.
