DXD: The Villainous Devil Signs-in into the Mash-up Anime World

Kuoh Academy.

Old School Building.

Lucien pushed open the door and stepped inside.

He had been invited here as a guest.

The one who invited him was Rias—Rias Gremory.

She was a girl who could be considered top-tier in terms of talent, strength, and beauty.

Of course, aside from these inherent traits, she was also a decorative vase.

But even as a vase, she was the most exquisite, most luxurious one.

The younger sister of a Maou, heir to a pure-blood devil family, an alluring top-tier beauty, and the wielder of the Power of Destruction—these titles alone were enough to prove her excellence and noble status.

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

The elegant red-haired beauty's fair and delicate legs, as smooth as white jade, instantly caught Lucien's gaze.

"A graceful lady is a gentleman's desire."

Besides—

Lucien was well aware that Rias was deliberately showing off.

If she was purposefully presenting it, acting aloof and pretending not to look would be foolish. Lucien wasn't someone who had cultivated such restraint.

He didn't hide his gaze.

Rias noticed his eyes lingering on her chest and thighs.

However, instead of being displeased, she revealed a satisfied smile.

Lucien carried the bloodline of a succubus. Capturing his attention was, in a way, proof of her charm.

"Akeno, serve the tea."

"Yes, President."

At Rias's command, a black-haired Yamato Nadeshiko dressed in a shrine maiden outfit smiled as she poured tea.

The one serving tea was Himejima Akeno—Rias's "Queen."

At school, Himejima Akeno was just as famous as Rias.

One was Western, the other Eastern. If the two of them could be stacked together… that would certainly be an experience unlike any other.

Lucien took a sip of the tea, and the refreshing aroma immediately put him at ease.

"As expected of Miss Akeno. Your tea-brewing skills are truly exceptional."

Akeno covered her lips with her hand and chuckled softly. "Ara~ Ara~ To receive such praise from Lord Lucien is truly my honor."

"By the way, this tea is so delicious—can you pour a cup for my Agumon as well?"

Lucien wasn't the kind to enjoy things alone.

Agumon had been by his side since childhood, inseparable from him.

If he had something to eat or drink, Agumon deserved a share too.

"Agumon?"

Rias was momentarily stunned, a flicker of displeasure flashing across her eyes, though she quickly suppressed it.

"Agumon... You mean that monster that's always following you?"

The reason Rias felt somewhat irritated was that she hadn't expected Lucien to request tea for a monster.

To put it bluntly, this could even be considered an insult to her.

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

Despite her irritation, Rias still agreed to Lucien's request.

After all, she had invited him here for a reason.

A few minutes later, a teacup several times larger than an ordinary one was placed on the table.

Rias specifically used a lower-quality teacup.

Then again, considering she's a pure-blooded devil, it's natural for her to look down on beasts.

This is my mistake. If only I could feed Agumon more, allowing it to evolve into a WarGreymon, our lives would be much better.

"Agumon, come out and have a taste. The tea is quite nice."

Light flickered.

A yellow, dinosaur-like beast emerged from the contract in Lucien's hand and approached the table.

Unlike ordinary monsters that would either lap up the liquid with their tongues or gulp it down in one go, Agumon lifted the teacup in front of it and drank in a refined manner, just like a human.

In fact, its movements were even more elegant than Rias, a high-class devil.

Such human-like behavior left both Rias and Akeno visibly surprised.

"Lucien-kun, has this Agumon mutated? Are you planning to groom it as your 'Queen'?" Rias asked with curiosity.

Many high-class devils would begin training their "Queen" from a young age.

Among all pieces in a high-class devil's peerage, the "Queen" held the highest status.

If this Agumon was meant to be Lucien's future Queen, then her earlier actions might have been inappropriate.

She simply didn't want a low-level beast using her belongings.

But if this beast had human intelligence and formidable power, that would be another matter entirely.

Hearing this, Lucien shook his head.

"Rias, talking about a 'Queen' is still too early for me."

"I'm not like you guys. I'm not a pure-blooded devil, nor do I have any Evil Pieces yet."

If he were a pure-blooded devil, he wouldn't have to struggle so much just to feed Agumon. Wouldn't it be easier to strengthen himself instead?

"Ah… about that…"

Rias seemed to recall something, her expression turning slightly awkward as she quickly changed the topic.

"Actually, Lucien-kun, the reason I called you here today is to bring you two pieces of good news."

"Oh? Two? That's unexpected."

Lucien had thought she just wanted to conduct their usual transactions. He hadn't expected any surprises.

"First, regarding the request you made for me to collect beast corpses and blood samples."

"This dragon-type beast was about mid-tier devil level. Its price wasn't cheap. Here is its essence blood, and its corpse is here."

Rias placed a tray on the table.

On it were a silver box and a red vial.

The vial contained the beast's essence blood, while the box held its corpse, stored inside a spatial magic array.

"Mm, we've done so many transactions before. No need for me to check."

Lucien stowed the beast's corpse and blood into his coat pocket.

This was what he had asked Rias to find for him.

These materials could help Agumon grow stronger.

Although he had his own connections with the Fallen Angels to acquire evolution resources for Agumon, maintaining his sources from the devils was just as important.

"This counts as the first piece of good news. I'm quite curious—what's the second one?" Lucien asked with interest.

"The second piece of good news, huh~"

Rias licked her red lips, revealing a mysterious smile.

"The second good news… is this!"

Snap!

With a crisp snap of her fingers, crimson light illuminated the entire room.

On the table, within a teleportation magic circle, a finely crafted gift box slowly emerged.

"Devil Pieces."

Lucien narrowed his eyes. Within this exquisite gift box lay none other than the Devil Pieces!

"That's right, Devil Pieces."

"Lucien-kun, the second piece of good news is that, after approval from the Underworld, you have been granted the qualification to possess your own set of Devil Pieces!"

"Rias, normally, only high-class devils can possess Devil Pieces. Are you sure it's fine to give them to someone like me, a low-class devil?" Lucien asked, puzzled.

"It's totally fine~"

"After all, Lucien-kun, you are now the 'heir to the Leviathan bloodline,' aren't you?"

"A true Demon King's successor without his own pieces? That would make the Underworld a laughingstock in the eyes of other factions~" Rias waved her hand dismissively, as if explaining the obvious.

So that's how it is. The reasoning behind giving me these pieces is more or less what I expected.

But if the Underworld is already working on this kind of image maintenance, it suggests that the devils are preparing to establish alliances with other pantheons.

"Since it's already been placed in front of me, I guess I'll shamelessly accept it."

Lucien extended his hand, officially forming a contract with the set of Devil Pieces.
