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

In the territory of the Agares family, within a floating city.

Inside a specialized testing area.

Grayfia stepped forward to introduce the person in charge of Akira's evaluation.

"Akira-sama, this person will oversee your strength assessment today."

"You should recognize her, so I won't go into too much detail."

Following Grayfia's gesture, Akira saw a quiet, bespectacled beauty.

It wasn't Sona, nor was it Tsubaki.

Her name was—Seekvaira.

Seekvaira Agares.

She was the next head of the Agares family, one of the Four Maou of the new generation in the original storyline (alongside Rias, Sona, and Sairaorg).

Seekvaira's demeanor was similar to Sona's—both were intelligent, bespectacled beauties skilled in strategy and tactics.

In fact, Seekvaira even shared the same nickname as Sona—the "Princess of the Underworld."

Currently, there were only three female demons with the title of "Princess of the Underworld."

They were—Rias, Sona, and Seekvaira.

Generally, there were only two types of demons who could earn this title.

The sister or daughter of the current Demon King.

The female heir of one of the top three demon families (House of Bael, House of Agares, House of Vapula).

...

Adjusting her glasses, Seekvaira extended her hand toward Akira.

"Hello, Akira Leviathan. I'm Seekvaira Agares."

"Hello, Lady Seekvaira."

Akira shook her hand briefly, intending to pull away immediately.

However, Seekvaira suddenly gripped his hand firmly with both of hers.

"Akira-kun, can I call you Akira-kun?"

"Akira-kun, can I ask you a somewhat personal question? Are you interested in robots?"

Seekvaira's crimson eyes sparkled with enthusiasm.

She was a robot enthusiast.

Having lived for so long, this was the first time she had met a fellow young demon who shared her interests, and she was thrilled.

"Robots? I suppose I'm interested, but why do you ask?" Akira chuckled awkwardly.

"Because I oversee the affairs of the Agares family. Recently, Serafall-sama has placed numerous orders for mechanical-type demon beasts and precious metals."

"I initially thought that Serafall-sama, who loves magical girls, had changed her tastes and developed an interest in robots."

"But Serafall-sama told me that it wasn't her who wanted the mechanical-type demon beasts and precious metals—it was you, Akira-kun."

"....."

Akira was speechless.

Well, it was true. He needed the mechanical-type demon beast data and precious metals for Agumon to evolve into MetalGreymon.

Confirming that Akira shared her interests, Seekvaira eagerly extended an invitation.

"Akira-kun, there's a Gundam exhibition in Tokyo soon. Would you like to go together?"

"Ahem—Lady Seekvaira, I believe matters regarding robots can be discussed after Akira-sama completes his evaluation," Grayfia interjected with a cough, reminding her.

"Ah... you're right. I got too carried away."

Seekvaira composed herself and returned to her professional demeanor.

In her work mode, Seekvaira shed her earlier fangirl persona and reverted to the quiet, composed beauty she was known to be.

"Akira-kun, this time, we will be responsible for your ability assessment."

"The results of this test will be recorded in the Underworld's war game simulation system, so please take it seriously."

"We?"

Akira raised an eyebrow.

"Yes, we."

Seekvaira nodded.

A few seconds later, a familiar face emerged from the door behind her.

"Yo~"

"Isn't this Akira? Long time no see." The demon youth rubbed his groggy head, his gaze dark as he stared at Akira.

"Diodora Astaroth." Akira raised an eyebrow.

"That's right, it's me!"

"Didn't expect me to come back so soon, did you?" Diodora's gentle face twisted slightly.

Seeing the tension between the two, Seekvaira stepped between them.

"Diodora, I don't know what issues you have with Akira-kun."

"But please, don't cause any trouble here."

"Since you volunteered to be part of this evaluation team, you'll need to follow my rules."

"Hmph!~"

Diodora snorted and turned away.

"Diodora, I didn't expect you to be so meek in front of your fiancée," Akira taunted with a smirk.

That's right.

Seekvaira was Diodora's fiancée.

(Note: This is an original setting.)

Like Riser, Diodora was a groom who needed to marry into a powerful family!

Unlike the original storyline, Diodora hadn't yet risen to power and broken off the engagement.

In the original story, he first obtained Ophis's "Snake," then assassinated the previous heir, and finally succeeded in becoming the next head of the family, freeing himself from the arranged marriage.

[But then again, given Seekvaira's strength, it's no wonder Diodora doesn't dare provoke her.]

Akira had already used an appraisal skill on Seekvaira the moment they met and knew she had become a high-class demon.

[Name: Seekvaira Agares (♀)]

[Level: LV175 (Mid-tier High-class Demon)]

[Attribute Evaluation]

[Note: Strength within the same level.]

[Strength: B]

[Speed: A-]

[Magic Power: A]

[Physical Durability: B]

[Martial Arts/Spell Proficiency: A (Proficient in the Agares family's ancestral spells, with exceptional talent in robotics and research.)]

[Sacred Gear/Bloodline Ability: S- (Pure-blooded demon lineage, with a time-based magic attribute.)]

[Overall Evaluation: A- Tier High-class Demon.]

[Final Assessment: A young pure-blooded demon with immense potential. If she fully develops her magic attribute, she will at least reach the level of a Maou.]

Soon, under Seekvaira's guidance, Akira completed his physical examination.

"Akira-kun, your test results are in."

Seekvaira handed him a report.

"Akira-kun, your current strength is at the level of a low-tier high-class demon."

"Your physical strength, magic capacity, and magic density are all at average levels."

"Your spell construction speed and completeness are below average."

"As for your bloodline development, it's the lowest among your peers, showing no signs of awakening."

"Based on my analysis, the reason for your recent improvement is likely due to your contracted demon beast."

"The evolution of your contracted beast has stimulated the vitality of your demon lineage, even awakening your magic."

"In terms of combat, I recommend that you utilize both magic and physical combat. The magic awakened through this stimulation may not have much room for further growth unless your demon beast evolves again."

"As for your future training direction, I suggest you follow the path of Sairaorg Bael from the House of Bael."

"Sairaorg Bael, like you, doesn't possess strong magic. However, he trained his body to an invincible level using the demon race's vitality and physical prowess, making him the top among young demons."

Snap.

With that, Seekvaira closed the report, looking every bit the professional.

"I see. Thank you for your advice, Lady Seekvaira."

Akira pretended to take her words seriously, though in reality, he paid them little mind.

After all... these results were all fabricated by him.

On the other side.

"Phew..."

After hearing Akira's results, Grayfia let out a sigh of relief.

Akira hadn't awakened the pure-blooded Leviathan lineage.

In her eyes, this was the best possible outcome.

Without awakening the Leviathan bloodline, he wouldn't be supported by the remnants of the old Maou faction and dragged into the vortex of rebellion.
