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

Kuoh Academy.

Old School Building.

Chiba Akira pushed the door and entered.

He was invited here as a guest.

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

She is a top-tier beauty with exceptional talent, strength, and looks.

Of course, aside from these natural attributes, she herself is just a vase.

However, even as a vase, she is the most exquisite and luxurious one.

The younger sister of the Demon King, the next head of a pure-blooded demon family, a stunning beauty with an impressive figure, and a wielder of destructive power.

These identities are enough to prove her excellence and nobility.

...

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

The aristocratic red-haired beauty's delicate and tender thighs, akin to white jade, fiercely attracted Akira's gaze.

A graceful lady is a gentleman's delight.

Moreover,

Akira knew that Rias was intentionally showing off to him.

Even though she pretended not to notice after deliberately showing off, Akira wasn't so ascetic as to ignore it.

Akira didn't hide his gaze.

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

However, instead of getting angry, she revealed a satisfied smile.

Akira has the bloodline of a succubus; her ability to attract his attention also indirectly demonstrated her charm.

"Akeno, serve tea."

"Yes, President."

After Rias called out, a black-haired Yamato Nadeshiko in a shrine maiden outfit smiled as she poured tea.

The one pouring tea is named Himejima Akeno, Rias's "queen."

In the school, Himejima Akeno is a beauty senior on par with Rias.

One is Western-style, the other Japanese-style; if they could be combined, it would definitely be unique.

....

"....."

Taking a sip of tea, the refreshing aroma put Akira in a good mood.

"Indeed, Miss Akeno, your tea-making skills are exceptional."

Akeno lightly covered her red lips and smiled slightly: "Ara ara~ To receive praise from Lord Akira is truly my honor."

"By the way, can I get a cup of this delicious tea for my Agumon as well?"

Akira isn't the kind of person who hogs everything for himself.

Agumon has accompanied him since childhood and is inseparable from him.

If he has something to eat, Agumon should have something too.

"Agumon?"

Rias was taken aback for a moment; a hint of displeasure flashed in her eyes but was quickly suppressed.

"Agumon... is that the monster that has been following you around, Akira-kun?"

Rias was somewhat annoyed because she didn't expect Akira to let a monster drink her tea.

To put it more seriously, this could even be seen as disrespect towards her.

"Akeno, brew another cup of tea with larger teaware."

Although somewhat angry, Rias still agreed to Akira's request.

After all, she had invited Akira for something she needed from him.

....

A few minutes later, there was an oversized teacup at the table that was several times larger than an ordinary teacup.

[Rias specifically changed to a lower-grade teacup.]

[However, it's normal for Rias as a pure-blooded demon to look down on monsters.]

[It's my fault; if I could feed Agumon more things to evolve into a Battle Greymon, our lives would improve significantly.]

"Agumon, come out and try this tea; it tastes quite good."

A flash of light flickered.

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

It walked up to the table.

Agumon did not drink it all at once or lick it like ordinary monsters would.

Instead, it lifted the teacup in front of it and drank like an ordinary humanoid being.

Its posture was even more elegant than that of Rias herself as an upper demon.

....

This human-like behavior surprised both Rias and Akeno.

"Akira-kun, could it be that this Agumon has undergone mutation? Are you planning to train it as your queen?" Rias asked curiously.

Many upper demons cultivate queens from a young age. Among all their subordinates, the "queen" holds the highest status.

If this Agumon were to be Akira's future queen, then what she did would indeed be somewhat disrespectful.

She simply didn't want low-level monsters using her things.

But if this monster possesses human-like intelligence and great power, then it would be another matter entirely.

.....

Upon hearing this, Akira shook his head.

"Rias, talking about queens is still too early for me."

"I'm not like you; I'm not a pure-blooded demon and don't have any demon pieces yet."

If Akira truly had pure-blooded demon bloodlines, he wouldn't need to think hard about feeding Agumon; he could just use it himself.

"This..."

Rias recalled something and smiled awkwardly before quickly getting to the point.

"Actually, Akira-kun, I called you here this time because I have two good news for you."

"Oh? Two? That's quite unexpected."

Akira thought Rias called him just for routine trading but didn't expect there would be unexpected joy.

...

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

"This dragon-type monster has strength around that of an intermediate demon; its price isn't low. Here's its essence blood and its corpse is over here."

Rias presented a plate.

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

The vial contained monster essence blood while the box contained the monster corpse stored in a spatial array.

"Hmm, we've traded so many times already; I won't check it."

Akira put the monster corpse and essence blood into his pocket.

These are what he asked Rias to help him find.

These items can help Agumon grow stronger.

While he still has channels on the fallen angel side to obtain evolution resources for Agumon, maintaining channels on the demon side is also necessary.

.....

"This counts as the first good news; I'm very curious about what the second good news is." Akira said with great curiosity.

"The second good news~"

Rias licked her red lips and revealed an inscrutable smile.

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

"Snap~"

Rias snapped her fingers; crimson light illuminated the entire room.

On the table within the teleportation array appeared an exquisite gift box slowly materializing.

"Demon pieces."

Akira narrowed his eyes; what was contained in this exquisite gift box was precisely demon pieces!

"That's right; demon pieces."

"Akira-kun, the second piece of good news is that after certification by the underworld, you have obtained the qualification to possess demon pieces!"

.....

"Rias, generally speaking only upper demons can possess demon pieces; is it really okay for someone like me who's a lower demon?" Akira asked curiously.

"No problem at all~"

"Who told you that you are now an 'heir of Leviathan bloodline'?"

"As an heir of true demon king bloodline, if you don't even have your own pieces, it would make underworld laughable in front of other powers~" Rias waved her hand explaining.

[I see now; my reasoning for giving me pieces aligns closely with what I thought.]

[However, since underworld has started improving its face project,it indicates that demons are ready to form alliances with other divine systems.]

"With this presented before me,I can only shamelessly accept them."

Akira extended his hand and officially contracted with these demon pieces.
