Furina, Please Let Me Steal Your Heart!

Many years later, Luna would undoubtedly recall the moment of her first formal encounter with this Fontaine "god."

It occurred not long after she had become a "Phantom Thief."

-

The sudden stab of pain pierced through Luna's hazy mind, jolting her into clarity. She moved her aching body, slowly straightening up.

"Where am I...?"

As she looked around, familiar objects filled her vision.

"Right, my name is Luna..."

Not long ago, she had taken a sip of wine and fallen into a dream. In that dream, she lived in another world, clutching a device called a cell phone.

A golden light flashed, and two golden figures appeared on the screen.

Wow, a dual-gold!

In her awe, she failed to notice the speeding cement truck bearing down on her. In an instant, it hurled her into this realm of Teyvat, reborn into her current form.

Luna rubbed her temples. Though it was just a dream, it felt disturbingly vivid.

Could my past life have really been like that?

Come to think of it, crashing a car right after witnessing a dual-gold event—was that a stroke of luck or sheer misfortune? And of all things, it had to be the world of "Genshin Impact"...

I played "Star Rail," though! she thought, feeling lost.

She'd barely dabbled in Genshin Impact, only vaguely recalling the storyline up to Liyue.

Now, she found herself in a place called Fontaine—a country completely foreign to her, rendering her previous knowledge of the game's plot almost useless.

In any case, after that hazy dream about her past life, Luna slept like a log until nightfall.

She picked up a mirror and gazed at her reflection.

Cascading golden hair draped over her shoulders, its vibrant sheen complementing her wine-colored eyes that sparkled with captivating beauty.

Anyone who glanced at her would think she was a beautiful young girl.

And Luna thought so too.

Except for this chest area...

But that's no big deal; cuteness comes first!

Besides, it's not that bad. As long as it's not completely flat like a pencil, it's fine.

Putting aside her beauty, Luna was more focused on one thing:

[Enter a name for your thief identity:]

A translucent panel floated within her field of vision.

Based on her memory, this thing seemed to be some sort of System...

"Name? Thief? What's this about?" Luna wondered.

But she received no response.

With a 'why not' attitude, Luna typed in a name: Super Wife Stealer.

[Are you sure you want to use "Super Wife Stealer"?]

Hmm... Better stick with something normal, or when making my grand entrance, it'd be:

"'Super Wife Stealer' strikes again! Today, I'll steal your Wife!" — No matter how she thought about it, it didn't sound funny.

[Are you sure you want to use "White Cat"?]

YESYES!

Even though she was a blonde, it didn't stop her from choosing this name.

There was only one question: Is there any creature more adorable than a cat in this world?

[Registration successful.]

[Treasure information discovered: Furina's Smile]

[Treasure information discovered: Clorinde's Eye Mask]

[Treasure information discovered: Neuvillette's Walking Stick]

[Treasure information discovered: Maiden's Tears]

In an instant, numerous windows popped up, making Luna's head spin.

Even though so many impressive-looking features appeared, she still couldn't figure out what this system was all about. Thus, she decided to skip through them one by one.

After fumbling with it for quite some time, she finally got a general idea of how the system worked.

"The Phantom System," as its name suggests, was a system that turned her into a Phantom Thief and aided her in progressing further down that path.

A Phantom Thief, unlike a regular thief or bandit, was more akin to a... sophisticated pickpocket who engaged in a form of behavioral art.

Before stealing any treasures, one must always send a warning letter to the target, letting them know in advance.

You're the White Cat, and tonight, I'll snatch your sister.

It was something like that. Of course, this wasn't a system for kidnapping people, so there would never be a case where "treasure equals human."

Maybe...

Once the target saw the warning letter, the system would recognize it as the start of a quest.

Upon completing the quest, the system would evaluate it based on the following criteria:

1. Level of Vigilance

2. Rarity of Treasure

3. Fame of the Act

4. Magnificence of the Heist

After the evaluation, points would be calculated. These points could then be used to upgrade skill trees, acquire new powers or knowledge, and gradually become the strongest Phantom Thief.

However, the treasures themselves would have to be found by the user.

rumors, personal observations, newspapers, etc.—any method or channel could be used.

Knowledge is power to steal.

Stealing succeeds brings pure delight.

From delight, seek more knowledge; continue to steal and succeed. The more one steals, the greater the pleasure; the more pleasure, the more one steals.

But it's clear this behavior defies rules and order. If caught, the penalty isn't just defeat... no, it's imprisonment in Meropide for forced labor.

Then I'd truly be in a giant cell, and there'd be no laughing about it.

As a Fontainean with common sense and moral principles, Luna naturally feels...

Absolutely thrilled to have access to the Phantom System!

Since getting caught leads to catastrophe, I'll just avoid capture, right? With such power at my disposal, not using it would make me the real joke.

What to steal is entirely her choice.

What kind of Master Thief she becomes is also up to her.

To embrace her zero-morale mindset, Luna flips through the list of known treasures without hesitation.

The captain's eye patch counts as a treasure too?

There's something indescribably subtle about this. If she truly steals it, wouldn't she become just a clothes thief?

After scanning through, Luna selects two pieces of treasure intelligence:

[Furina's Smile]

[Information: This painting is an oil-on-canvas work by Fontaine's renowned painter, created with Furina's permission as his model. The use of pigments and brushstrokes is incredibly precise, with proportions perfectly harmonious. Undeniably, this is a masterpiece from a true master.]

[Initially, Furina had wanted to cradle the cat, but the feline lashed out, striking her face and escaping. Despite the setback, Furina maintained her elegant smile—a testament to her composure. This painting will be showcased at the art exhibition hosted by the Confrerie of Cabriere.]

Treasure: Oil painting of Furina

Rarity: A

Fixed Point Value: 300

Next to it was another item:

[Tears of a Maiden]

[This gemstone, crystal clear and aquamarine in hue, exudes a sense of life even in its solid form... Upon closer inspection, one can almost hear the weeping of a young girl. Is this a gemstone or perhaps amber?]

[The item will be on display at the art exhibition hosted by the Confrerie of Cabriere.]

[Rarity: B]

[Fixed Point Value: 250]

The Confrerie of Cabriere, Luna echoed in her mind.

She rose from her seat and approached a board covered in various intelligence notes.

Though she no longer considered herself part of "them" and now operated as an individual adventurer, she had maintained her habit of gathering information.

Luna tapped her chin thoughtfully. "So the exhibition is in one week..."

Luna knew well that the Confrerie of Cabriere was an ally of the Spina di Rosula, having received significant support from them since its inception.

If she attempted to steal these two items, it was highly likely that she would encounter members of the Spina di Rosula.

Her gaze shifted, settling on a particular image.

"The current president of the Spina di Rosula is Navia Caspar... a formidable opponent. But with an opportunity to seize two treasures in one strike, there's no reason not to proceed."

The Confrerie of Cabriere feels strange though, she mused, particularly in terms of their itinerary...

Insufficient clues for now. Luna shook her head, deciding to set the matter aside for the time being.

With her target firmly in mind, the remaining task was clear: meticulous preparation for the operation lay ahead.
