In DxD Starting with Sign-Ing in as the Red Dragon

Kuoh Academy.

Old School Building.

Chiba Akira pushed open the door and stepped inside.

He had been invited here as a guest.

The one who invited him was named Rias, Rias Gremory.

She was a young woman whose talent, strength, and beauty were all considered top-tier.

Of course, aside from these innate qualities, she was also somewhat of a "decorative piece."

But even as a decorative piece, she was the most exquisite, the most lavishly adorned one.

The younger sister of a Maou, the next head of a pure-blooded demon family, a stunning beauty with an enviable figure, and a wielder of the power of destruction.

These titles were more than enough to prove her excellence and nobility.

...

Noticing Akira's arrival, Rias smiled politely and uncrossed her legs.

The sight of the noble red-haired beauty's smooth, jade-like thighs instantly caught Akira's attention.

"Fair ladies are the desire of gentlemen," as the saying goes.

Moreover, Akira knew full well that Rias was intentionally showing off for him.

If she was deliberately putting on a display, it would be hypocritical of him to pretend not to notice. Akira wasn't that ascetic.

He made no effort to hide his gaze.

Rias, too, noticed Akira's eyes wandering over her chest and thighs.

However, far from being offended, she instead smiled with satisfaction.

Akira had succubus blood in him. If he was drawn to her, it only proved her charm.

"Akeno, serve the tea."

"Yes, President."

After Rias gave the order, a black-haired Yamato Nadeshiko in a shrine maiden outfit gracefully poured the tea.

The one serving the tea was named Akeno Himejima, Rias's "Queen."

At school, Akeno was a beauty on par with Rias, a senior known for her elegance.

One was Western-style, the other Japanese-style. If the two were to overlap, it would undoubtedly create a unique flavor.

...

"..."

Akira took a sip of the tea, and the refreshing aroma soothed his mood.

"As expected of Akeno-san, your tea-making skills are truly unparalleled."

Akeno lightly covered her lips with her hand and smiled. "Ara ara~ To receive praise from Akira-sama is truly an honor."

"By the way, this tea is so good. Could I get a cup for my Agumon as well?"

Akira wasn't the type to keep good things to himself.

Agumon had grown up with him and was always by his side.

If he had something good, Agumon deserved a share too.

"Agumon?"

Rias was momentarily taken aback, a flicker of displeasure crossing her eyes, but she quickly suppressed it.

"Agumon... that's the monster that's always by your side, right?"

The reason Rias was a bit upset was that she hadn't expected Akira to ask for tea for a monster.

To put it bluntly, it could even be seen as a slight against her.

"Akeno, prepare another cup of tea. Use a larger teacup."

Though slightly annoyed, Rias still agreed to Akira's request.

After all, she had invited him here because she needed his help.

...

A few minutes later, a much larger teacup appeared on the table.

[Rias had specifically switched to a lower-grade teacup.]

[But then again, it was only natural for Rias, a pure-blooded demon, to look down on monsters.]

[It was my fault. If I could have fed Agumon more resources and helped him evolve into WarGreymon, our lives would have been much better.]

"Agumon, come out. Try this tea. It's really good."

A flash of light.

A yellow dinosaur-like monster emerged from the contract in Akira's hand.

Walking up to the table, Agumon didn't gulp down the tea or lap it up like a typical monster.

Instead, he lifted the teacup and drank it like a human would.

His posture was even more elegant than that of Rias, a high-class demon.

...

This display of human-like behavior surprised both Rias and Akeno.

"Akira-kun, could it be that this Agumon has mutated? Are you planning to raise him as your Queen?" Rias asked curiously.

Many high-class demons would start grooming their Queens from a young age.

Among a high-class demon's servants, the "Queen" held the highest status.

If this Agumon was destined to be Akira's Queen, then her earlier behavior might have been somewhat rude.

She simply didn't want a lowly monster using her belongings.

But if this monster possessed human-like intelligence and formidable power, that was a different story.

...

Hearing this, Akira shook his head.

"Rias, it's too early for me to think about Queens."

"I'm not like you. I'm not a pure-blooded demon, and I don't have any Evil Pieces yet."

If Akira truly had pure-blooded demon heritage, he wouldn't be struggling to feed Agumon. Wouldn't it be easier to just use the resources himself?

"Ah, right..."

Rias seemed to remember something and quickly changed the subject.

"Actually, Akira-kun, I called you here because I have two pieces of good news to share."

"Oh? Two? That's unexpected."

Akira had thought Rias called him here just for their usual transactions. He hadn't expected any surprises.

...

"First, the monster corpses and blood you asked me to collect."

"This dragon-type monster has strength equivalent to a mid-tier demon, so it wasn't cheap. Its essence is here, and the corpse is in this box."

Rias presented a tray.

On the tray were a small silver box and a red vial.

The vial contained the monster's essence, while the box held the corpse stored within a spatial array.

"Since we've done this so many times, I won't bother checking."

Akira stored the monster corpse and essence in his pocket.

These were the items he had asked Rias to find for him.

They would help Agumon grow stronger.

Although he also had connections with the fallen angels to obtain resources for Agumon's evolution, maintaining ties with the demon side was equally important.

...

"That's the first piece of good news. I'm curious about the second one," Akira said with interest.

"The second piece of good news~"

Rias licked her lips and smiled mysteriously.

"The second piece of good news... is this!"

Snap.

Rias snapped her fingers, and a crimson light filled the room.

On the table, within a teleportation array, an exquisite gift box slowly materialized.

"Evil Pieces."

Akira narrowed his eyes. The item inside the beautiful gift box was none other than a set of Evil Pieces.

"That's right, Evil Pieces."

"Akira-kun, the second piece of good news is that, after approval from the Underworld, you've been granted the right to possess Evil Pieces!"

...

"Rias, isn't it usually only high-class demons who can possess Evil Pieces? Are you sure it's okay to give them to a low-class demon like me?" Akira asked, puzzled.

"It's fine, it's fine~"

"After all, Akira-kun, you're now the inheritor of the 'Leviathan Bloodline.'"

"If the inheritor of a true Maou's bloodline doesn't even have his own Evil Pieces, it would make the Underworld a laughingstock among other factions," Rias explained with a wave of her hand.

[So that's how it is. The reason for giving me the pieces is roughly what I expected.]

[But if the Underworld is starting to care about appearances, it means the demon faction is preparing to form alliances with other pantheons.]

"Well, since they're right in front of me, I'll have to accept them graciously."

Akira reached out and formally established a contract with the set of Evil Pieces.
