Elsewhere—
The following evening, after finishing his date with Yuma Amano, Lucien returned to his study.
After two days of dedicated effort, he had successfully refined the data Agumon needed for its evolution.
"Soon, I'll have a WarGreymon-level Digimon with the strength of a High-Class Devil!"
Lucien was thrilled.
Agumon was already strong.
Previously, it had been at the peak of a Mid-Class Devil's strength but could barely hold its own against High-Class Devils.
Once it evolved, WarGreymon would likely dominate its rank entirely.
As Lucien basked in excitement, a system notification chimed in his mind.
[Ding!]
[Congratulations, Host! Villain Sign-In Triggered!]
[Sign-In Tier: Silver.]
[Sign-In Type: Location Sign-In.]
[Ding!]
[Sign-In Location: A Full Set of High-Class Devil Pieces.]
"..."
"Hmm..."
Lucien fell into a brief silence, unsure how to react.
"Is this system only capable of giving me the easiest sign-in tasks?"
Muttering his complaints, Lucien took out his set of Devil Pieces.
[Ding!]
[Congratulations, Host! Villain Sign-In Completed!]
[Sign-In Tier: Silver.]
[Sign-In Location: Devil Pieces.]
[Reward Acquired: Transcendent Pieces.]
[Transcendent Pieces: A modified and upgraded version of standard Devil Pieces that break racial limitations, allowing continuous growth beyond original potential. Significantly enhances the user's talent.]
[The stronger the recipient's fortune and the more frequently they appear in the storyline, the greater their talent boost.]
[Note: As the King, the Host can use the abilities of subordinates and exert complete control over them. If the target is in a state where they cannot resist, a piece can be implanted forcefully.]
[Transcendent Pieces come in two sets: one black and one white, representing two different paths—light and darkness.]
[In addition to their immense power, they possess extreme concealability.]
[The Host can modify their appearance and data to perfectly mimic standard Devil Pieces. As long as an excessive number are not summoned at once, their true nature will never be exposed.]
The glow faded.
A chessboard appeared before Lucien.
The original blood-red Devil Pieces had vanished.
In their place, two neatly arranged sets of black and white pieces lay before him.
"Agumon!"
Without hesitation, Lucien summoned his childhood companion, Agumon.
"Take this."
From the board, Lucien picked out two exquisite Queen Pieces—one black, one white.
He wasn't sure which would be better for Agumon, so he decided to test both.
One thing, however, was certain—
Agumon would absolutely be his "Queen."
[Lucien, what is this?]
Agumon held the two pieces, gazing curiously at Lucien.
"These are enhanced Devil Pieces. They'll improve your talent and growth potential. Choose the one that resonates most with your body."
[I see. Understood.]
Realizing these pieces would make her stronger and help her evolve, Agumon carefully began sensing them.
[I think this one suits me better.]
In the end, Agumon chose the white Queen Piece.
Lucien was slightly surprised.
Given Agumon's ability to evolve by absorbing life data, it seemed more fitting for her to take the black Queen Piece.
But since Agumon had instinctively chosen the white one, Lucien respected her decision.
Returning the black piece to Lucien,
Agumon held the purified magical beast data in one hand and the white Queen Piece in the other before closing her eyes.
A bright white light filled the room.
The Queen Piece slowly fused into Agumon's body.
Soon, Agumon's entire body turned white.
Within the radiance, her form rapidly changed—her height surging beyond human proportions.
[Agumon, Evolve!—]
[Greymon!—]
[Ding!]
[Host's Bonded Contract Beast has Successfully Evolved.]
[Congratulations, Host! You now possess the Bonded Contract Beast—Greymon!]
A massive dinosaur-like beast burst forth, instantly filling Lucien's study!
Boom!~
Greymon's size was so immense that the second and third floors collapsed under the strain!
Standing before Lucien was a towering Greymon, nearly fifteen meters tall!
"Good!"
"All that feeding wasn't in vain!" Lucien couldn't help but praise.
His Agumon had developed incredibly well—far stronger than the average.
Otherwise, he wouldn't have poured so many resources into its growth.
In Digimon Adventure, Taichi's Agumon was less than a meter tall.
Lucien's Agumon, however, had already been taller than him before evolving!
Taichi's Greymon in the first season stood around five to six meters tall.
Lucien's Greymon? Fifteen to sixteen meters!
"If this evolution continues, it might even reach the legendary WarGod Greymon!"
WarGod Greymon was a title from the newer Digimon series—given to Taichi's WarGreymon for its godlike combat abilities.
At full evolution, with a towering height of fifty to sixty meters, it could easily pass as a kaiju from an Ultraman episode!
[Sorry, Lucien. I damaged your house.] Greymon lowered its head, apologizing in a deep voice.
She hadn't expected her evolution to make her so massive, instantly wrecking Lucien's study.
It was just a house.
Lucien, of course, wasn't about to blame Agumon for it.
"No worries~ We'll just get another villa."
"Your strength is far more valuable than any mansion."
[Mm, understood, Lucien. I'll train even harder.]
Greymon nodded, her body glowing once again.
A few seconds later—
Greymon's size gradually shrank, reverting to Agumon's original form.
[Lucien, I think I prefer this form.]
[I'm more familiar with it, and this way, I can stay by your side all the time.]
"That makes sense. Shrinking down does make things a lot more convenient."
Lucien nodded, acknowledging Agumon's reasoning.
His Agumon wasn't regressing due to stunted growth.
Since she could freely control her evolution and de-evolution, she could do as she pleased.
The noise from the study was significant.
Sensing the commotion in the villa,
a blonde-haired, blue-eyed woman hurried into the study.
"Young Master Lucien, what happened?!"
The woman scanned the room, taking in the destruction.
Was this… a terrorist attack? Or another one of Lucien's experiments?
The woman was Lucien's housekeeper and maid—Nao Hayasaka.
That's right.
She was Nao Hayasaka, the mother of Ai Hayasaka from the world of Kaguya-sama: Love is War.
Initially, Lucien had been unsure of her identity, but after learning that she was a widow and had a daughter named Ai Hayasaka, he confirmed it—
This was indeed the same Nao Hayasaka he was familiar with.
Nao Hayasaka was fully aware of Lucien's status as a noble Devil and had loyally served him as his head maid.
While she wasn't particularly strong—only a reincarnated Low-Class Devil—she was incredibly versatile.
She excelled in household chores, cooking, etiquette, negotiations, and even business dealings.
It was because of her that Lucien had wanted to test Yuma Amano in the first place.
She... was Lucien's perverted blonde maid.
Of course, Nao Hayasaka wasn't always like that.
Most of the time, she was reliable and composed.
Inside the study—
Looking at the wreckage before her, Nao Hayasaka sighed and rubbed her forehead in exasperation.
Oh well.
This wasn't the first time Young Master Lucien had blown up a room. She was used to it by now.
"Young Master Lucien, please relocate to the guest room for now. I'll take care of the study and have it restored as soon as possible."
"Guest room?"
Lucien raised an eyebrow. Usually, she would tell him to return to his room or the main hall. Why the guest room today?
"Yes, the guest room."
"The next head of the Sitri family, Sona Sitri, will be visiting in an hour."
"She seems to have something important to discuss with you and has specifically requested your presence."
"Sona has finally come looking for me?"
Lucien chuckled and made his way toward the guest room.
Fine.
Let's see how his so-called fiancée planned to break off their engagement.
Standing at the study's doorway, Nao Hayasaka watched Lucien's departing figure with a hint of worry.
[I just hope Young Master Lucien doesn't do anything reckless.]
[Right now, his status no longer holds much value.]
[Ending his engagement with the Sitri heiress and gradually fading into the background would be the safest option.]
