===

Two hours later. Finally, Saber declared her surrender.

The noble King of Knights had ultimately fallen to the cunning schemes of the Demon King.

There was no helping it. The time-manipulation abilities of a God-Slaying Sacred Gear in its Balance Breaker state were simply too overpowered. The accumulation and sudden release of pleasure had overwhelmed even the steadfast will of the King of Knights, causing her to willingly seek the Demon King's affection.

Before collapsing, Saber glanced at Rin Tohsaka, who was beside her.

She admitted that she had underestimated Akira's capabilities.

Not only Rin, but even she herself... was no match for Akira.

"Hmm... should I call for more reinforcements?" Akira muttered as he looked at the fallen Saber.

He hadn't expected this move to be so devastating. Even Saber, who had reached a level beyond that of a Demon King, couldn't withstand it.

Time-based abilities were truly broken, no matter how they were used.

Several more hours passed.

By the time Rin Tohsaka regained consciousness, it was already dark outside.

"Mmm... ugh..."

Letting out a few adorable groans, Rin began her usual waking-up routine.

Hearing her voice, Sakura Matou smiled softly, observing Rin's face, which still bore traces of exhaustion.

"Big sister, you're awake?" Sakura's gentle voice reached Rin's ears.

For the past ten years, this was how Sakura had been waking Rin up.

"Sakura... get me some water..." Rin mumbled, not even opening her eyes.

"Of course, big sister."

A few seconds later, a cup of warm water was placed by Rin's side.

"Thanks... Sakura."

Rin struggled to sit up and took a sip of the water.

Indeed, it was a blessing to have Sakura by her side.

It was a blessing that Sakura had escaped the Matou household.

Wait... escaped the Matou household?

At that thought, Rin's mind snapped awake.

Right! They weren't in the future! They had traveled back to the past, ten years ago!

To be precise, the future timeline they had experienced had never truly existed!

That timeline was merely a simulation created by the world's consciousness to maximize their potential!

Realizing this, Rin finally came to her senses.

Yes... the past was something they could never return to...

As Rin was lost in her thoughts, a familiar sound reached her ears.

The sound was mixed with the faint rustling of fabric, soft yet unmistakable.

"Is that... Mother's voice?" Rin stiffened, turning her head toward the source of the sound.

There, she saw Aoi Tohsaka's green sandals rising and falling rhythmically.

From the emerald nail polish on Aoi's delicate toes, Rin caught a glimpse of her own gaping mouth.

What had happened while she was asleep?

And the medicine by Aoi's side... why did it look so familiar?

Wait, was that medicine Aoi had bought for herself?!

"Rin?"

Aoi's gentle gaze fell on Rin, though her eyes soon rolled back in pleasure.

"Rin, you understand, don't you?" Aoi's voice was tender yet filled with longing.

"..."

Rin wanted to say something, but the words caught in her throat.

After all... she had no right to stop Aoi from pursuing her own happiness.

In truth, Aoi wasn't their biological mother. She was their aunt.

Akira's time-traveling had not only saved Shirley and Natalia but had also altered the fates of many others.

For example, Taiga Fujimura, Claudia, Aoi Tohsaka... and so on.

After the timeline changed, Tokiomi Tohsaka had still married a woman from the Tohsaka family, but it wasn't Aoi—it was her older sister.

Due to the world's correctional forces, Rin and Sakura were still born.

Unfortunately, their biological mother's health rapidly deteriorated after giving birth, and she passed away soon after.

To give the children a more complete family, Tokiomi decided to leave them in the care of the Zenjou household.

This way, Aoi, their aunt, could raise them as their mother.

As for Tokiomi, he would visit periodically to teach them magecraft.

During her time as their mother, Aoi had given up her personal life to devote herself entirely to raising Rin and Sakura.

It wasn't until Aoi's death that Rin learned from Kirei Kotomine that Aoi wasn't their biological mother.

Compared to the mother she had never known, Rin believed that Aoi was their true mother.

And now...

Rin had witnessed a different side of Aoi.

This Aoi was no longer just a mother but a woman.

A woman who, after giving up her right to love for so long, had finally found happiness with a man.

"Mother... no, Aoi."

Rin felt that calling Aoi "Mother" no longer felt appropriate.

"It's fine, Rin. You can still call me Mother," Aoi replied with a warm, maternal smile.

"Yes... Mother..."

Rin watched as Aoi's face radiated happiness, and tears of mixed emotions streamed down her face.

On one hand, she was happy for Aoi. On the other, she felt guilty for the years Aoi had sacrificed for her and Sakura.

As Rin wallowed in her guilt, a gentle breeze carried the scent of lavender, and Sakura's purple hair cascaded around her.

Sakura had embraced her sister.

"Big sister, there's no need to feel so sad. Mother is happy now, isn't she?" Sakura's voice was soothing.

"Yes... this is her salvation... and our atonement."

Rin sighed, accepting the reality of the situation.

However, as she did, a sharp glint appeared in her eyes.

Rin flicked her twin tails and glared at Akira, who was still with Aoi.

"Hey! You damn Demon King! If you dare hurt Mother, I'll never forgive you!"

"..."

Akira remained silent for a few seconds before smiling and calling out to Rin.

"Rin..."

"What... what is it?" Rin felt uncomfortable under Akira's gaze, which seemed to look at her as if she were his daughter.

"Rin, do you remember the promise we made?" Akira asked.

"Promise? What promise?" Rin was confused.

"The one where I said I'd tell you if your score was higher than Luvia's."

"Now, I can officially tell you—"

"Rin, congratulations. If we include Sakura and Aoi, your score is... 100."

"Huh?"

"100? Really?"

For a moment, Rin was elated at having achieved a perfect score.

But a few seconds later, she realized what Akira meant.

"Who... who wants a score like that?!"

The thought of her score being inflated because of Sakura and Aoi infuriated her!

Even if it meant surpassing Luvia, she wanted to do it on her own! Relying on Sakura and Aoi didn't count!

A tie was fine!

She, Rin Tohsaka, would never accept a victory achieved through such means!

"So, you want me to score you again?" Akira's smile turned slightly mischievous.

"..."

Rin hesitated for a moment before regaining her composure.

"Fine! Bring it on! I've had enough of you bullying Mother!"

"Aoi is just an ordinary person. Bullying someone like her doesn't make you a hero!"

"To take on a Demon King, someone with both magecraft and Servant powers is more suitable!"

Rin, seeing Aoi's vulnerable state, felt it was her duty to step in.

With her Servant powers, Rin could take the lead, while Aoi, being an ordinary person, could only follow.

However, someone else wasn't about to let Rin take over.

"Big sister... you're overstepping your bounds."

Sakura's chains wrapped around Rin, restraining her.

"Sakura? What are you doing? Shouldn't you have already retired?"

Rin noticed the familiar scent on Sakura, realizing that Sakura had already "retired" from the competition.

Of course.

If Sakura had the time to take care of her, it meant Sakura had already finished her part.

"That's right, big sister. But there's still someone who hasn't retired yet," Sakura replied with a smile.

"Huh? Who's left?" Rin raised an eyebrow.

"Oh, and big sister, I forgot to tell you. Unlike you, I scored 97 points."

"What?! How?!" Rin immediately turned to Akira.

Hadn't Akira said he loved her legs and feet? She had gone all out! How could Sakura's score be higher than hers?

Did Akira find Sakura cuter and more beautiful than her?!

Damn it! Men and their lies!

"Big sister, don't misunderstand. I got that score because of Rider," Sakura explained with a smile.

"Rider?"

Rin's eyebrows shot up.

That's right.

Sakura had summoned the legendary Medusa as her Servant.

As a Heroic Spirit, Rider's charm was undoubtedly on par with theirs.

"Yes, Rider."

Sakura nodded.

"Rider's true body has been summoned from the Throne of Heroes."

"Come out and say hello to big sister, Rider."

At Sakura's call, a shadow emerged from her and flew to Aoi's side.

Soon, Rider took Aoi's place, saving her from the brink of exhaustion.

As Sakura had said, an hour ago, Akira had absorbed Rider's fortune.

Considering that Rider's power had reached the level of a Demon King after absorbing the pieces, Akira had put in considerable effort to conquer her.

[Ding~]

[Detected fortune absorption. High-dimensional succubus bloodline activated.]

[Fortune absorption target—Medusa (Rider).]

[Ding! Fortune absorption successful.]

[Host level increased by 9. Current level: 30 (Demon King-tier).]

An hour ago, thanks to Rider's fortune, Akira had taken another step forward on his path to becoming a Demon King.

"Damn it! I didn't expect this!"

Rin bit her lip.

If that was the case, then Sakura's higher score... made sense.

"Wait, if Sakura has Rider, then I have Saber!"

A brilliant idea popped into Rin's head.

Coincidentally, Saber was still in the room.

By the large window, Saber sat on a chair, sipping tea and reading a book.

Watching the chaos unfold, Saber shook her head in exasperation.

Having experienced Akira's time-manipulation abilities firsthand, she knew that Akira was just playing around.

As someone who only engaged in serious battles, this petty squabbling held no interest for her.

"..."

Rin was about to call out to Saber but noticed the familiar scent of dimensional energy on her.

In the end, Rin reluctantly withdrew her hand.

Meanwhile, in the DxD world.

Kuoh Town.

The Fallen Angel Governor, Azazel, was busy with his Sacred Gear research.

The door creaked open, and a serious-looking man walked in.

His name was Baraqiel.

A ten-winged Fallen Angel, known as the "Lightning of God," Baraqiel was a true powerhouse, surpassing even the likes of Kokabiel.

If Azazel was the leader of the Fallen Angels, Baraqiel could be considered the third or fourth in command.

"Azazel, a new prodigy has emerged among the Fallen Angels."

"I think... you'll be very interested in him."

"Oh? Why's that?" Azazel was curious about Baraqiel's confidence.

"Because... not only is he incredibly strong, but he also possesses exceptional research skills and the ability to construct powerful magical formulas."

"In my opinion, his research abilities might even rival yours."

"Someone like that... truly exists among the Fallen Angels?" Azazel raised an eyebrow.

It wasn't that he looked down on the Fallen Angels.

If there were a second Azazel, the Fallen Angels wouldn't be in their current state.

"He's the real deal."

"Anyway, he's quickly gained the support of many high-ranking Fallen Angels thanks to his research prowess."

"You mentioned wanting to step down after the peace treaty is signed, right? If you do, he's a strong candidate to succeed you as Governor." Baraqiel finally got to the point.

"So... why are you telling me this?" Azazel leaned back, a playful smile on his face.

"Azazel, you know why," Baraqiel replied, rubbing his temples.

"Alright, I get it."

"I'll personally test him. Does that satisfy you?" Azazel sighed, a wry smile on his face.
