===

After learning about the various details of time travel from the system, Akira's mind was filled with questions.

[If the heroines in the story could break free from their original fates by absorbing his energy...]

[Then, what would happen to those who couldn't escape their destined paths?]

The system had mentioned that changes would occur, but they would still be confined within the boundaries of fate. However, it hadn't specified the extent of these changes.

What Akira wanted was concrete experimental data on how much could actually be altered.

Thus, Akira chose Maiya Hisau as his test subject.

He believed this experiment was necessary.

His time for traversing through fate was limited, and he couldn't possibly use those brief moments to win over everyone he wanted to.

If he forced things, he might gain their affection but not the fortune needed to level up.

Therefore, Akira chose a more subtle approach. Instead of leaving his dimensional energy in every person whose fate needed changing, he focused on altering their destinies.

The rewards could be reaped later.

So, Akira left certain restrictions on some individuals, like the young Maiya Hisau, ensuring that the characters he targeted wouldn't be taken by others. Then, he left.

He wanted to see what changes would occur if Maiya Hisau didn't have his dimensional energy within her.

Now, the results were in—Maiya Hisau still participated in the Holy Grail War, but her role was no longer that of Kiritsugu Emiya's assistant and lover. Instead, she became his senior disciple.

Akira was satisfied with the results.

From now on, when he traveled through time, he could use this method to claim others or even revive those who had already died.

As Akira looked at the guilt-ridden Maiya Hisau, he couldn't help but see the little girl who had once held his hand.

"Maiya, you don't need to blame yourself."

"No, Lord Akira, it's my fault. About Natalia..." Maiya faced Akira directly.

"That really wasn't your fault..."

Akira sighed helplessly and extended his hand. The cross in Rin Tohsaka's possession flew back to him. After resting in his palm for a few seconds, it shot toward Maiya Hisau.

"Whoosh~"

In an instant, the cross returned to Maiya's chest.

As the cross settled, a new memory surfaced in Maiya's mind.

"This is... Natalia?"

Maiya saw the scene of Akira rescuing Natalia from the plane.

"Wait! Natalia was infected, wasn't she? So... Kiritsugu lied to me?!"

Realizing this, Maiya's eyes turned fierce.

It made sense.

After killing his father and adoptive mother, Kiritsugu Emiya had evolved into his complete form.

If he could kill his parents, wife, and daughter, deceiving a senior disciple with whom he had little emotional connection was nothing.

Now that Maiya knew Akira had saved Natalia, she finally found the courage to face him.

"Lord Akira!"

Just like the little girl she once was, Maiya threw herself into Akira's arms.

"There, there."

Akira gently stroked Maiya's hair.

Hmm, the once unripe fruit has now matured. It's time to harvest.

While comforting the cool beauty in his arms, Akira turned his gaze to Irisviel.

Aside from Maiya, he had also intervened in Irisviel's affairs.

Akira was quite pleased with the results of his experiment with her.

Thanks to his interference, Kiritsugu Emiya was now merely a mercenary for the Einzbern family, with no marital ties to Irisviel.

Irisviel's fiancé... was someone else.

"Irisviel, do you know... what this is?"

Akira extended his hand, conjuring a drop of blood.

"This feeling is...!"

Irisviel covered her lips with her hand, her toes curling within her black stockings.

Now she understood why she had felt that strange sensation when Akira touched her feet by the beach.

So...

Akira was her fiancé?

After the timeline changed, Akira had still completed the "sign-in" by touching Irisviel's feet at the beach.

However, her reaction was much stronger this time, nearly causing her to collapse. The reason was simple—her body now contained a trace of Akira's demonic bloodline.

During his fate traversals, Akira had accessed several time nodes before "Kiritsugu Emiya married into the Einzbern family."

At the time nodes involving Shirley and Natalia, Akira hadn't just focused on his romantic pursuits. He had also made preparations for future events.

For example, he had contacted the Einzbern family in advance and struck a deal with them.

The subject of the deal... was naturally Irisviel.

In order to enhance the attributes of their homunculi, the Einzbern family had traded with Akira for a trace of demonic power.

Ultimately, this power was applied to Irisviel.

"So... Akira is the fiancé chosen by my family?" Irisviel's expression was complex, unsure how to respond.

Akira was her fiancé, and he had the power to free her from the fate of becoming a Holy Grail vessel.

This realization left Irisviel more conflicted than ever.

After the timeline changed, she no longer had the will to "obtain the Holy Grail for Kiritsugu's dream."

Her participation in the Holy Grail War was solely at the behest of her family, nothing more.

Seeing Irisviel's hesitation, Akira knew she was at a crossroads.

He had the power—and the necessity—to erase her doubts.

"Irisviel, come with me."

"You don't need to worry about the Holy Grail anymore."

"As for the Einzbern family, you don't need to concern yourself with them."

"Have you forgotten? A few days ago, I conquered the Einzbern family."

That's right! When Illya went missing, news also came that the Einzbern family had fallen!

Irisviel's eyes widened. Did this mean the Einzbern family was now under Akira's control?

Understanding everything, Irisviel recalled Akira's words about taking her away.

Her affection for Akira had already been high due to Illya, but now it skyrocketed.

"Yes! Akira! I'll go with you!"

"Thank you... Thank you for everything you've done for me and Illya. Thank you... for saving us from the fate of becoming Holy Grail vessels..."

Irisviel embraced Akira, tears in her eyes, and pressed her lips to his in a tender, inexperienced kiss.

Meanwhile, Maiya, still in Akira's arms: ???

Soon, the light of a teleportation array flashed, and Akira, along with the two women, began to fade away.

Seeing Akira about to leave, Rin Tohsaka, who had just regained some strength, hurriedly took control of her younger self's body, transforming into the teenage Rin.

"Hey! Wait! I still have questions for you!"

"I heard from Sakura that Mom..."

Before Rin could finish, Akira's figure vanished completely.

"Tch!"

Rin clicked her tongue in frustration. She had wanted to ask Akira about her mother, Rin Tohsaka.

On one hand, she wanted to know how her mother was doing under Akira's care. On the other hand, after days of separation, she missed her dearly.

Rin hadn't been able to ask Akira directly.

However, she soon found a new target for her questions.

"Thud~"

As the dust settled, two young girls arrived late to the scene.

"Sakura! And Illya!"

Rin had countless things she wanted to say, but all that came out was, "Why are you so late? Did you run into trouble?"

Rin Tohsaka—a sister who could never be harsh with her younger sibling.

"Yes, Sister. We were delayed by the barrier outside," Sakura nodded, surveying the battlefield.

"Even with Berserker's strength, I couldn't break through it quickly," Illya sighed.

However, after sighing, she covered her mouth and giggled.

Rin's disheveled state was simply too amusing.

Although the three of them had formed an alliance, their relationship was still as noisy as ever.

"Hmph! Laugh all you want! Your mom just got taken away by that man!" Rin snapped, her frustration boiling over.

That scoundrel Akira already had Sakura and Illya wrapped around his finger, and now he had other lovers too?!

Seeing Irisviel plant a passionate kiss on Akira, Rin felt an ominous premonition.

Could it be that her mother, Rin Tohsaka...

No.

That's impossible.

Absolutely impossible.

Rin knew full well that Irisviel and Illya were homunculi created by the Einzbern family. Their mother-daughter relationship was nominal at best, more akin to sisters.

Their tragic fate destined them to become Holy Grail vessels, so it was natural for them to be moved by someone who could save them.

Moreover, from what Akira had said earlier, it seemed he had long since established a marital arrangement with the Einzbern family.

Her mother, Rin Tohsaka, would never be as forward as Irisviel.

Rin was right.

Rin Tohsaka hadn't been forward.

She had been passive at first, but then she gave in completely.

Especially after learning of Tokiomi Tohsaka's death, things had spiraled out of control.

"By the way, Sakura, isn't Mom with you? Can I see her again?" Rin asked, turning to Sakura.

Having failed to protect her father, Rin had grown even more dependent on her mother.

After days without seeing her, she longed for her mother's embrace.

"Ah... about that... How about we go see her now?" Sakura awkwardly smiled, then took Rin's hand and led her toward the inn.

If they wanted to see Rin Tohsaka, it had to be now.

It was still afternoon.

Any other time—morning or night—Rin Tohsaka would either be unavailable or too exhausted.

So, Sakura decided to take Rin to see her mother while Akira was away.

As for bringing Rin into the fold... Sakura wasn't opposed to the idea.

She just felt the timing and circumstances weren't right. It could wait for a better opportunity.

And so, Sakura led Rin away.

The battlefield was now left to Illya and Luvia.

Illya's eyes sparkled with mischief.

She had no intention of following Rin and Sakura. She had her own plans.

"If I head to the Einzbern castle to see Mom in two hours, I can still have some fun before then."

Illya crouched down and reached out to touch Luvia's golden hair.

"What are you doing?!"

Luvia jumped back.

Since her future self wasn't particularly powerful, Luvia could maintain her adult form for extended periods.

Known as the "Crane Wing Princess," Luvia possessed not only great physical strength but also an enviable figure.

Illya eyed Luvia's curvaceous body, accentuated by her noble dress, her well-developed hips, and ample chest.

I see... So Dad still prefers the mature type, huh?

Illya sighed, glancing down at her own petite frame.

Ten years have passed, and I'm still this small. Guess I'm stuck like this forever.

Seeing Akira add another voluptuous subordinate to his ranks, Illya couldn't help but feel displeased.

Of course, her displeasure was directed at Luvia.

"You... are Dad's new subordinate?" Illya placed her hands on her hips, her short stature somehow exuding an air of authority.

"I... suppose so," Luvia replied, a bitter smile on her face as a white chess piece floated above her chest.

She wasn't sure whether this was fortunate or unfortunate.

In any case, she had become a subordinate to a high-dimensional demon, effectively severing her ties to this world.

This unequal relationship, which seemed to offer benefits, left her wondering—should she submit or resist?

Seeing Luvia's confusion, Illya grinned like a little devil.

She had just thought of a way to tease both Luvia and Rin, all while earning her father's praise. It was a win-win-win situation!

"Luvia, you don't get along with Rin, do you?"

"Then, how about we team up to prank her?"

"Oh?"

Luvia's ears perked up.

Even as a subordinate to a high-dimensional demon, her love for mischief hadn't waned.

"Do tell."

Illya leaned in and whispered her three-birds-one-stone plan into Luvia's ear.
