"Rias, didn't I tell you that Akira went out for training?" Sona replied.

"But who goes out for training and still shows up at school from time to time?" Rias

countered.

She knew that Akira's appearances had become less frequent, but he wasn't

completely unreachable.

"Rias, instead of asking me, wouldn't it be better to ask Akira directly?"

"Fine, I'll have Koneko pass him a message."

Rias could tell that Sona wasn't willing to share any information with her.

In truth, Rias wasn't really expecting to get any answers from Sona about Akira. She

was simply testing the waters, trying to see if there was still something between Sona

and Akira. From the results of her probing, Sona remained tight-lipped, revealing

nothing unusual about her relationship with Akira.

So, Rias decided to drop the matter. Whether Sona truly had nothing going on with

Akira or was deliberately hiding something, Rias knew she wouldn't get any

information out of her if Sona didn't want to share.

Sona, on the other hand, was well aware of Rias's intentions. However, she couldn't

reveal too much to Rias without consulting Akira first. After all, Rias wasn't yet

considered one of their own. Not only had she not been absorbed into their group, but

her engagement to Akira was also based on political interests. Such a Rias was

someone Sona couldn't fully trust.

"Then I'll take my leave now, Rias. You can continue your discussion with Seekvaira-

sama."

With that, Sona and Tsubaki Shinra disappeared into a teleportation circle.

Rias's gaze lingered on the spot where the circle had been. There was still one big

question on her mind: When had Sona and Seekvaira become so close that they were

sharing an office? Weren't they worried about leaking confidential information?

Even if Sona was handling school matters, which shouldn't be a secret from

Seekvaira, what about Seekvaira herself? Didn't she fear that information about the

House of Bael might leak?

Setting aside her doubts for now, Rias turned her attention back to Seekvaira and

resumed their discussion.

"Seekvaira, I think these spirit medicines would be the most suitable."

"As the head of the House of Bael, you've dealt with many things. Do you have any

better suggestions?"

Although Seekvaira was only the "acting head," Rias wasn't foolish enough to address

her as such. That would be far too tactless.

"Well... I think these spirit medicines might be more useful for you, Rias. Given your

Destruction magic, which is different from ordinary Devils, you could try some with

stronger effects."

"Since your goal is to stabilize your foundation and consolidate your power, as long as

the medicine isn't the type that forcibly boosts your power, a stronger spirit medicine

for foundation-building shouldn't be harmful to you."

Seekvaira quite liked Rias as a client. In fact, not just Seekvaira, but many others

appreciated Rias's generous spending. If it hadn't been for Rias providing a year's

worth of magical beast data, Akira might have had to wait another three months to

evolve Agumon without using any cheats.

"Alright, thank you, Seekvaira. I'll consider it carefully."

Rias accepted the list from Seekvaira and began verifying the information through

other channels.

Meanwhile, in Akira's world—the Fate universe.

A few days ago, after obtaining the Holy Grail, Akira had used the Dragon Soul of the

Star Sea Dragon King to take the Fate world with him. During this time, Akira had been

dividing his attention between the Fate world and matters in the DxD world.

Last night, Akira had gone out for a late-night motorcycle ride with Taiga Fujimura and

only returned in the early hours of the morning. Now, it was already the evening of the

next day.

Due to Akira's habits, he was still resting within Taiga's body. Sensing some

movement, Akira slowly opened his eyes to find Taiga admiring his sleeping face.

If Akira had to guess, Taiga had been watching him since she woke up.

Taiga smiled instinctively when she saw Akira wake up, but then her eyes rolled back

slightly as she reacted to his presence.

The younger, teenage version of Taiga Fujimura, with her long hair and toned physique,

exuded a youthful charm that Akira found far more appealing than her older, short-

haired self.

After a moment, Taiga finally recovered and shot Akira a playful glare. However, Akira's

reaction had piqued her interest.

So, without much thought, the young Taiga leaned in close to Akira's ear and

whispered, "Akira... I'm hungry. The taste of dimensional energy is quite nice. What do

you think... should we consume it internally or apply it externally?"

Faced with Taiga's invitation, Akira replied, "I think we can do both—consume it

internally and apply it externally. By the way, I've been really into pineapples lately.

They add a nice flavor."

"Pineapples, huh..."

The young Taiga recalled the information about pineapples. Last night, she had indeed

caught a whiff of that fresh, fruity scent.

"Whether it's pineapples or something else, I'm hungry. As my fiancé, isn't it your duty

to satisfy your fiancée's needs?" Taiga interlocked her fingers with Akira's and sat on

his lap.

The younger version of Taiga, acting spoiled like this, had a unique charm.

Last night, after several days of dating, Taiga had finally accepted Akira as her fiancé.

There was no helping it—he had apparently set his sights on her over a decade ago,

even before she was born, by arranging a marriage contract with her parents. It was all

too cunning.

[Ding~]

[Detecting the acquisition of fate energy. High-dimensional Succubus bloodline

activated.]

[Fate energy acquisition target—Taiga Fujimura.]

[Ding! Fate energy acquisition successful.]

[Host level increased by 3. Current level: 236 (High-class Devil).]

During the second round, Akira suddenly heard a cute, loli-like voice in his ear.

[Akira-sama, Rias-sama is looking for you. Are you available now?]

The voice belonged to Koneko Toujou, who was contacting Akira through their shared

connection as part of his peerage.

"Rias is looking for me? Now? I'm a bit busy, but I can make some time if it's urgent. Is

it something serious?"

Akira was indeed occupied at the moment. The second round was taking place on

Taiga's motorcycle. On a deserted highway late at night, Akira was riding the heavy

metal bike at breakneck speed. Taiga, wearing a tight riding suit, sat in front of him, her

long hair flowing in the wind as her eyes rolled back, nearly collapsing onto the bike's

front cover.

This novel experience was something Akira wasn't willing to interrupt unless Rias was

in a life-or-death situation.

[It's not that urgent, but Rias-sama mentioned that it's time for you to fulfill your

contract. She hopes you can come to the old school building by noon tomorrow.]

"Fulfill the contract? So... Riser has come knocking?"

"Alright, I understand. Koneko, tell Rias I'll be there on time tomorrow."

[Understood, Akira-sama. I'll relay the message to Rias-sama.] Koneko nodded.

"By the way, Koneko, did you forget something?" Akira reminded her.

[What did I forget?] Koneko was puzzled.

"Didn't we agree that you'd call me 'Akira-senpai' instead of 'Akira-sama'?"

"I prefer being called 'senpai' by cute girls like you."

This wasn't just for Koneko. Akira also enjoyed having Rin Tohsaka and Sakura Matou

call him "senpai." With Sakura, it was to savor her sweet voice, while with Rin, it was

purely to see her tsundere reactions.

[Alright, I understand... Akira-sen... Akira-senpai...]

Koneko finally managed to stutter out the word.

"Good, keep it up. I'm looking forward to your future performance, Koneko-chan."

As a reward for Koneko calling him "senpai," Akira also used a term of endearment for

her.

[Yes, Akira-senpai. I'll work hard to gain the strength to defeat my sister soon.]

Koneko's response was a bit off. While Akira had asked her to work on calling him

"senpai," Koneko instead talked about training harder.

Back in the DxD world, after ending the communication with Akira, Koneko let out a

long sigh.

"Phew..."

Feeling the powerful immortal energy within her body, Koneko's gaze was filled with

confusion.

Koneko had now ascended to the rank of a High-class Devil, and a high-tier one at

that. She was now close to reaching the level of her sister, Kuroka, who was at the

peak of the High-class Devil rank.

"High-class Devil..."

"The fact that I've gained the strength to face my sister is all thanks to Akira-senpai."

"Such a great debt... how can I ever repay it?"

Koneko thought back to a few days ago.

A few days prior, Akira's Mutation Piece had advanced to the second stage, unlocking

its full potential and significantly strengthening his peerage. To help those without

pieces and to guide those who had experienced a sudden increase in power, Akira had

returned to the DxD world for a brief period.

During that time, Akira had given pieces to many, including Seekvaira and Sona (the

advanced Mutation Pieces were even more discreet and couldn't be detected). He

had also provided guidance to Asia and others.

Koneko was one of those who received guidance.

After Akira helped her refine her meridians and adjust her body, Koneko, who had

already reached the mid-tier High-class Devil rank, advanced to the high-tier High-

class Devil rank.

It was during that time that Koneko discovered Akira's proficiency in immortal

energy—something even she, as a Nekoshou, couldn't match. His top-tier immortal

energy massage techniques had left Koneko utterly captivated. Combined with the

further evolution of Akira's high-dimensional Succubus bloodline, Koneko's affection

towards him had increased significantly.

With her strength now at a level where she no longer feared her sister suddenly

appearing to kidnap her or harm those around her, Koneko's focus shifted to a more

personal matter.

Akira-senpai had done so much for her. How could she ever repay him?

Perhaps... by offering herself?

Such a great debt could only be repaid by giving herself to him.

The fact that Akira preferred being called "senpai" instead of "sama" suggested that he

might have feelings for her, right?

But...

What if her flat chest didn't interest him?

What if she confessed, only for Akira-senpai to tell her that he was just being kind and

didn't have any romantic feelings for her?

This internal conflict was why Koneko had been reluctant to call Akira "senpai." Every

time she did, it only deepened her confusion.

[Wait!]

Koneko's golden eyes narrowed as she thought of a solution.

[My sister has a great figure, right?]

[Since we're twins, my body shouldn't be limited to this flat chest!]

[I've heard there are immortal techniques that can enhance physical development. If I

use those, maybe I can achieve a figure as perfect as Rias-senpai's!]

Koneko had found a new goal.

Now, she had another reason to grow stronger!

She would defeat her sister Kuroka and force her to reveal the secret to improving her

figure!

[With that decided, it's time to train!]

Koneko sat cross-legged, filled with determination to defeat her sister and obtain the

secret to enhancing her figure. She began her training in earnest.
