On the other side.

The next evening, after completing his date with Amano Yuuma, Akira returned to his study.

After two days of going all out in purifying the data, Akira had finally completed the data purification needed for Agumon.

...

"Soon, I will have a Greymon with strength equivalent to a high-class demon!"

Akira was thrilled.

Agumon was incredibly powerful.

Previously, Agumon's strength was at the peak of mid-class demons, but it had the terrifying potential to rival high-class demons.

Once evolved, wouldn't Greymon be invincible among high-class demons?

Just as Akira was getting excited, he suddenly heard the system's notification.

[Ding!~]

[Congratulations, host, for triggering a Villain Check-in!]

[Check-in Level: Silver.]

[Check-in Type: Location Check-in.]

[Check-in Location: A set of high-class demon pieces.]

"..."

"Hmm....."

Akira pondered for a few seconds, unsure how to react.

"Is this system only capable of giving out the easiest check-ins?"

While complaining, Akira took out his own set of demon pieces.

[Ding!~]

[Congratulations, host, for completing the Villain Check-in!]

[Check-in Level: Silver.]

[Check-in Location: Demon Pieces.]

[Congratulations, host, for receiving the reward: Exceptional Pieces.]

[Exceptional Pieces: A higher-tier version of the original demon pieces, allowing the pieces to break through the original racial limits and continuously grow stronger, significantly enhancing the talent of the piece's owner.

The stronger the user's luck and the more they appear in the plot, the greater the talent enhancement.]

[Note: As the King, the host can use the abilities of their servants and has complete control over them. As long as the target is in an unresisting state, the pieces can be forcibly implanted.

The Exceptional Pieces come in two sets, one black and one white, with different enhancement directions for light and dark.

In addition to their powerful effects, they are also highly concealable.

As the King, the host can adjust the appearance and data of their pieces to match ordinary demon pieces. As long as an excessive number of pieces are not summoned at once, there is no risk of exposure.]

As the light faded.

A chessboard appeared before Akira.

The blood-red demon pieces disappeared.

In their place were two neatly arranged sets of black and white pieces.

...

"Agumon!"

Without hesitation, Akira summoned Agumon, who had grown up with him.

"Here, take this."

One black and one white, two exquisite Queen pieces were taken out by Akira from the chessboard.

Akira wasn't sure which piece Agumon would adapt to, so he decided to try both.

Because one thing was certain.

Agumon would definitely become his "Queen."

...

[Akira, what is this?]

Agumon held the two pieces, looking at Akira curiously.

"These are enhanced demon pieces that can improve your talent and potential. You can choose the one your body feels more drawn to."

[I see, I understand.]

Realizing that this was something that could make her stronger and help her evolve, Agumon began to carefully sense them.

[I think this piece suits me better.]

In the end, Agumon chose the white Queen piece.

Agumon's choice surprised Akira.

For a beast like Agumon, who evolved by absorbing life data, it seemed more fitting to choose the black Queen piece.

However, since Agumon said she felt the white Queen piece suited her better, Akira supported her choice.

...

After returning the black piece to Akira.

Agumon held the purified beast data in one hand and the white Queen piece in the other, slowly closing her eyes.

A white light illuminated the entire room.

The Queen piece gradually merged into Agumon's body.

Soon, Agumon's entire body turned white.

In the white light, Agumon's form began to change, rapidly growing from her original height.

[Agumon evolve!—]

[Greymon!—]

[Ding!~]

[The host's contracted beast has successfully evolved.]

[Congratulations, host, for obtaining the contracted beast—Greymon!]

A giant dinosaur-like beast rose from the ground, instantly filling Akira's study!

"Boom!~"

Due to Greymon's enormous size, the floors of the second and third stories were shattered!

Before Akira stood a massive Greymon, about fifteen meters tall!

"Great!"

"All that feeding wasn't in vain!" Akira couldn't help but praise.

His Agumon had developed exceptionally well, far stronger than the average Agumon.

Otherwise, he wouldn't have invested so many resources without hesitation.

In the first season of Digimon, Taichi's Agumon was less than a meter tall.

But Akira's Agumon, even before evolving, was already taller than Akira!

Taichi's Greymon in the first season was only about five to six meters tall.

But Akira's Greymon was a whopping fifteen to sixteen meters!

"If this evolution continues, it might even evolve into the legendary 'WarGreymon'!"

WarGreymon, known as the "God of War Greymon," is a title from the new Digimon series.

The reason it's called the God of War is because of its god-like combat prowess!

Not to mention, standing at fifty to sixty meters tall, it could easily play a monster in an Ultraman series!

...

[Sorry, Akira, I broke your house.] Greymon lowered her head, her deep voice apologizing.

She hadn't expected to grow so large after evolving, instantly destroying Akira's study.

It was just a house.

Akira certainly wouldn't blame Agumon for that.

"It's fine~ We can just move to another villa."

"Your strength is far more important than any villa."

[Okay, I understand, Akira. I'll work hard to train.]

Greymon nodded, her body once again glowing with white light.

A few seconds later.

Greymon's form shrank, returning to Agumon's appearance.

[Akira, I think this form is better.]

[I'm more familiar with this body, and in this form, I can always stay by your side.]

"True, being smaller is definitely more convenient."

Akira nodded, agreeing with Agumon's reasoning.

His Agumon wasn't stunted in growth, after all.

Since she could control her evolution and devolution, he'd let her decide.

...

The commotion in the study was significant.

Hearing the noise from the villa.

A blonde, blue-eyed woman hurried to the study.

"Akira-sama, what happened?"

The blonde woman entered the study, surveying the wreckage.

Was this... a terrorist attack? Or was Akira conducting another experiment?

...

The blonde woman was Akira's butler and maid, named "Hayasaka Nao."

That's right.

She was Hayasaka Ai's mother, "Hayasaka Nao," from the world of "Kaguya-sama: Love is War."

At first, Akira wasn't entirely sure of her identity, but after learning that her husband had passed away and she had a daughter named Hayasaka Ai, Akira finally confirmed that this blonde woman was indeed the Hayasaka Nao he knew.

Hayasaka Nao was aware of Akira's status as a demon noble and had been serving him as his butler.

Although her strength wasn't great—she was only a low-class reincarnated demon—she was incredibly versatile, excelling in household chores, cooking, etiquette, and even negotiation and business.

The reason Akira wanted to conduct an experiment with Amano Yuuma was because of her.

She... was the perverted blonde maid in Akira's household.

...

Of course, Hayasaka Nao wasn't always perverted.

Normally, she was quite reliable and composed.

In the study.

Looking at the devastation before her, Hayasaka Nao sighed helplessly.

Oh well.

It wasn't the first time Akira-sama had blown up a room. She was used to it.

"Akira-sama, please move to the reception room for now. I'll handle the study and restore it as soon as possible."

"The reception room?"

Akira raised an eyebrow. Normally, she'd tell him to return to his room or go to the hall. Why the reception room today?

"That's right, the reception room."

"The next head of the Sitri family, Sona Sitri, will be visiting in an hour."

"She seems to have something very important to discuss with you and insists that you make time."

...

"So, Sona is finally coming to see me?"

Akira chuckled and headed to the reception room.

Good.

He'd see how his so-called fiancée planned to break off their engagement.

...

At the study door, Hayasaka Nao watched Akira's retreating figure with concern.

[I hope Akira-sama doesn't do anything drastic.]

[Nowadays, his status holds little value. The safest course of action would be to dissolve the engagement with the Sitri family and gradually retire.]
