[As expected of Sakura.] Akira praised Sakura's initiative.

He had only asked Sakura to contact Mitsuzuri Ayako and Fujimura Taiga. He never instructed her to handle Tohsaka Rin's situation.

"It seems Sakura has forgiven Tohsaka Rin."

The reason Akira had kept Rin at arm's length was out of consideration for Sakura's feelings. If he were too proactive with Rin, Sakura might feel neglected.

So, until Sakura fully moved on, Akira had avoided direct contact with Rin.

However.

Now, it seemed that rule could be discarded?

Since Sakura was willing to take the initiative, it meant she had forgiven Rin.

[Akira-nii-san, I'm just fulfilling the promise we made long ago.] Sakura's gentle voice continued.

[I think a household with only you and Mother isn't enough. We can't exclude Sister.]

[Since Sister has carried this guilt for so many years and is willing to atone, then as her younger sister, it's my responsibility to forgive her.]

[Besides… letting Sister perish with the world would be too cruel for her.]

[As for what Sister owes me, I'll take my time to tease her back in the endless years to come.] At the end, Sakura revealed a hint of her "little devil" nature.

But compared to the deep-seated psychological issue of forgiving Rin, a bit of harmless mischief was perfectly normal.

Meanwhile, while Akira and Sakura were communicating, Rin had finished processing the information in her mind.

Rin looked at Akira, her blue eyes filled with astonishment.

She finally understood what Akira had just done.

She had thought Akira was just out saving people.

But she never expected that Akira had also performed the heroic feat of "saving the world" in the dimensional rift!

If it weren't for him, there would likely be far more invasive creatures in the world right now!

"Demon King Akira… you…"

Although Rin addressed Akira as the Demon King, her feelings and tone were different. She… felt an unprecedented sense of security.

It was the kind of feeling one gets from a father's care.

Rin missed that feeling.

However, she quickly snapped out of it, pushing those emotions to the back of her mind.

"That's right. I was protecting my assets," Akira replied calmly.

If this dying world hadn't been carved out by the system and destined to become his property, he wouldn't have bothered.

Let the taller ones deal with the collapsing sky. If things got too bad, he could always leave.

After all, he had the ability to traverse dimensions.

"Your assets, huh…"

Rin smiled wryly.

Well, demons… are extremely self-interested.

But this could also be interpreted another way—once something became a demon's interest, it would receive the demon's protection.

She and this world… had just experienced that firsthand.

After understanding this, Rin fully prepared herself. She made her resolve.

"Alright, Demon King Akira, I'm willing to form a contract with you."

"You don't even need to dissolve your contract with Sakura."

"Even if it's just to accompany Sakura."

"Even if it's just to make you think I, and this world, are valuable… I'm willing to form a contract with you."

When faced with crisis, humans always make choices that best ensure the survival of their species.

In Akira's previous life, there was a pair of siblings who, during a volcanic eruption, decided that since they were going to die anyway, they might as well enjoy themselves one last time.

However, whether it was fortunate or unfortunate, after they were done, they realized they hadn't died.

In the Einzbern Castle.

Inside the room assigned to Rin.

On the table were several types of medication.

Clomiphene citrate, Clomid, Letrozole, and so on.

These medications all had one common effect… promoting ovulation and aiding conception.

"Let's do this!"

Rin steeled herself and took the standard dosage of each medication!

It was do or die!

Even if something went wrong, that bone-crushing demon wouldn't let her come to any real harm!

With this in mind, Rin took several fertility drugs in one go!

Rin wasn't the type to carry such medications with her.

Her ability to be this reckless was thanks to someone else—Tohsaka Aoi.

Rin had a habit.

She always liked to be fully prepared.

So, before undertaking the task of continuing the Tohsaka bloodline, Rin had already considered using medication to aid conception.

However, aside from being overly prepared, Rin had another bad habit.

She always managed to mess things up at the last moment.

Just earlier, Rin had messed up again.

Before coming to the Einzbern Castle, Rin had been persuaded by Aoi to visit a pharmacy and purchase specialized fertility drugs. (For more exciting novels, visit Feilu Fiction!)

At the time, Aoi hadn't yet told Rin that she hoped the father of Rin's child would be Akira.

Later, after a long conversation and argument with Aoi, Rin had forgotten about the fertility drugs.

It wasn't until just now that Rin remembered she had bought them.

Well, now she could kill two birds with one stone—fulfill her mother's expectations and atone to her sister.

The guilt towards Sakura and the duty to continue the Tohsaka lineage had always weighed heavily on Rin's mind, her greatest burdens.

Now, an opportunity had presented itself to solve both problems at once, and she wasn't about to let it slip away.

But… she messed up again.

After searching for a while, Rin couldn't find the drugs she had bought earlier.

Finally, someone stepped in to help!

Aoi provided several fertility drugs, leaving Rin stunned.

"By the way… why would Mother carry so many fertility drugs with her?"

"Probably… to regulate hormones and avoid irregular periods?"

Rin could only think of the best possible explanation.

There was no way they were actually for conception, right?

Right! That must be it!—Mother knew about her forgetful nature and how she always managed to mess things up, so she had bought extra while they were shopping!

Rin quickly came up with a reasonable explanation for Aoi's actions.

Two hours later.

After taking a bath, Rin finally chose her favorite outfit. If possible, she wanted to add a bit of ceremony to the occasion.

Rin didn't wear anything special, just her usual red sweater, black thigh-high stockings, and her signature twin tails.

Feeling her slightly elevated body temperature and smoother skin, Rin confirmed that the drugs had taken effect.

After taking several deep breaths, Rin mustered her courage and opened the door to Akira's room.

And then…

She saw a golden-haired beauty in a blue-and-white aristocratic dress.

"Luvia! What are you doing here?!"

Rin couldn't help but shout at Luvia, who was elegantly crossing her white-stockinged legs.

"Ara? Isn't this Rin? What's wrong? You look like a loser. How amusing~"

Luvia's golden curls were adorned with pale blue ribbons, cascading down her shoulders and blending with the hem of her luxurious blue lace dress, which draped over Akira's lap.

Luvia seemed to think this wasn't intimidating enough, so she even pulled out a white folding fan and slowly opened it in front of Rin.

With the fan unfolded, Luvia perfectly embodied the image of a noble lady—if you ignored the fact that she was sitting on a man's lap.

"Don't tell me… while I was preparing, you were…!"

Rin took a step back.

She had considered the possibility that Sakura might come to help her, but she never expected Luvia to show up out of nowhere!?

In a way, Rin's guess wasn't entirely wrong.

Luvia had indeed come to Akira's room at this time because of Sakura.

Originally, Luvia had been persuaded by Illya to "treat a dead horse as if it were alive" and drag Rin into the same situation as herself.

But before the plan she and Illya had devised could be put into action, Sakura told her that "Rin is about to cook the rice"?!

So, without much thought, Luvia took the initiative to approach Akira.

Unlike Rin, Luvia had already been turned into Akira's servant, so she didn't have much of a choice. It was only a matter of time.

So, rather than waiting aimlessly, Luvia decided to "win" against Rin one more time!

As for Akira, he wasn't the type to refuse what was offered to him. In fact, he quite enjoyed watching these two rivals bicker in front of him.

Two hours ago, just as Rin was preparing, Luvia had already "cooked the rice."

[Ding~]

[Detected ongoing plunder of fate. High Succubus bloodline activated.]

[Fate plunder target—Luvia (Luviagelita Edelfelt)]

[Ding!~ Fate plunder successful.]

[Host level increased by 5. Current level: 201 (Low-tier Demon King)…]

As Akira's power grew, the fate of anime heroines had less of an effect on him.

Of course, the benefits he received were still proportional to their fate and his own strength, though the level increases weren't as significant as before.

After all, Akira had already ascended from a high-tier demon to a Demon King.

"Luvia! You did this on purpose!"

Even someone as dense as Rin could tell Luvia had planned this!

What kind of coincidence was this?

Even if it had been Sakura with Akira, she could have accepted it, but…

"Rin, you only realized this now?"

"Ohohohohoho~~"

Luvia opened her fan, laughing gleefully.

Why did it have to be you, Luvia!?

What she wanted to see was Rin's expression—this jealous, envious expression!!!~

Overcome with joy, Luvia's eyes rolled back, drool dripped from her mouth, and she lost the strength to hold her fan, only managing to flash a triumphant "I won" smile.

"Akira… you agreed to Luvia on purpose, didn't you?"

Rin expressed her dissatisfaction with Akira.

However, knowing Akira's nature as a Demon King, she didn't press the issue. If a Demon King didn't act like this, he wouldn't be a Demon King.

What she was really angry about was Luvia!

"This scheming woman ruined my plans! She must be punished!"

Rin's body lit up with the glow of her magic circuits.

Just like in the Clock Tower, she was going to settle things with Luvia!

"Rin! Don't even think about it!"

Luvia's body also lit up with her magic circuits, her well-trained muscles tightening as she resisted Rin's assault!

The sight of Luvia's magic circuits activated gave Akira an unprecedented thrill, further confirming the correctness of his actions.

"Ugh… guh…"

Due to Akira's… changes, Luvia's eyes rolled back, and her resistance weakened.

"Now's my chance!"

Rin seized the opportunity and reached for Luvia's hair!

Grabbing hair was the most effective move in a catfight!

Normally, she wouldn't resort to such tactics—she had some dignity.

But this time, Luvia had forced her hand!

"You think I'll let you win?!"

Luvia, being a woman herself, knew a woman's greatest weakness. She quickly turned to avoid Rin's grasp.

However, due to her current state, Luvia's turn was clumsy, and she collapsed from the force of the spin.

"Hmph! Luvia! You're too arrogant!"

Rin walked up to Luvia and kicked her a few times.

After confirming that Luvia was truly unconscious, Rin reached out to push her aside.

She planned to tie Luvia to the bed.

Hmph! Think you can mess with me? Rin would make sure Luvia paid for this!

However, the moment Rin grabbed Luvia's hand, Luvia grabbed hers in return!

"Rin! You fell for it!"

Luvia smirked slyly.

She had indeed passed out earlier from overexertion.

But she had only been out for a few seconds.

By the time Rin started kicking her, Luvia had already regained consciousness!

She had been waiting for this exact moment!

And so, on Akira's lap, the legendary "Devil Muscles Rin" and "Lady Crane" began their struggle.

Akira recalled a famous quote from his master: "I love watching women fight."

Wasn't this exactly why he had agreed to Luvia's advances?

Unfortunately, the catfight didn't last long.

Although Luvia could have held out longer, Rin started cheating.

Aside from her own power from ten years in the future, Rin also had Saber's strength!

With this advantage, Rin quickly turned the tables on Luvia.

"Hmph~"

Luvia smiled wryly.

If Rin was going to cheat, then she'd have to regain the upper hand another way!

Luvia weakly turned her body, her delicate toes curling as she trembled and spoke.

"Demon King-sama, if you were to rate my service, what score would you give me?"

"I believe you wouldn't lie about something like this, right?"

"Hmm… 95 points?"

Akira answered honestly.

He had to admit, Luvia's struggle with Rin on his lap had given him a uniquely thrilling experience.

"95 points? It seems I still have room for improvement…"

"Rin… I wonder, how many points will you get?"

With the last of her strength, Luvia uttered these words before finally passing out.
