In the world of Type-Moon, it all begins with becoming Morgan's husband!

Saber belongs to his sister Sakura Tohsaka, so he has to find another way.

However, Rin Tohsaka had no idea how this standard hand-kissing gesture had anything to do with the "passion" that Sakura Tohsaka had just mentioned.

This is something that could be done even under normal circumstances, right?

Why is it called passion?

Sakura Tohsaka seems to have predicted what her older sister was going to say once again.

The girl temporarily released Ian's hand, leaned close to her sister's ear, and whispered a question.

"Sister, do you know where there's a secluded spot near the school?"

"Hmm? A secluded place?" Rin Tohsaka blinked. "What do you want with a place like that?"

"because--"

Sakura Tohsaka gestured softly, almost as if showing off.

“Mr. Ian just told me… he really wants to do that kind of thing with me.”

"Wh-what?!" Rin Tohsaka immediately realized what was happening upon hearing this.

Her face flushed, but she quickly regained her composure.

"Sakura, you're not kidding, are you?"

"of course not."

Sakura Tohsaka's tone grew increasingly shy, as if she were about to melt away in the sweetness.

"Because it's not just Mr. Ian who has this idea..."

"Me...I have one too."

"..."

Realizing that her younger sister was indeed treating the summoned Servant as her boyfriend, Rin Tohsaka said nothing more.

She didn't like to criticize Sakura Tohsaka's behavior.

After all, it was the path she chose herself.

Besides——

Rin Tohsaka looked at Sakura Tohsaka, who had a happy expression on her face, and recalled what her mother, Aoi Zenjou, had mentioned that night.

"If Sakura and her Servant could become lovers, that would be a good option."

This is one way to preserve one's life in the Fifth Holy Grail War.

"I see."

Rin Tohsaka placed her hands on her hips.

"Luckily, I'm the vice president of the student council... otherwise I really wouldn't be able to help you and Ian with this."

Rin Tohsaka knows about your and Sakura Tohsaka's thoughts.

She borrowed a set of keys in her capacity as vice president of the student council.

You have no idea that it's the key to somewhere, and Rin Tohsaka has no intention of explaining it to you.

[You all walked up the stairs of the private Homurahara Academy.]

Finally, you arrived at your destination—the rooftop.

On the rooftop.

This is the highest point in the private Homurahara Academy. The ground here is covered with white tiles, and the area is surrounded by wire mesh.

Because it is indeed very high, most people would not notice it, let alone since school hasn't even started yet.

Rin Tohsaka locked the door and then put the bunch of keys into her pocket.

"All right."

"If you're going to do that kind of thing, this is definitely a good choice."

"Hmm~"

Sakura Tohsaka, who was responding to her sister, actually had her own little thoughts.

Although she knew that the Command Seals could force Servants to follow certain requirements, she was still somewhat uneasy.

after all--

This is the first time it has been used on Ian without any prior reference.

Sakura Tohsaka naturally wasn't very confident.

Otherwise, she wouldn't have wanted to conduct the test so quickly with her sister as a witness.

but--

As it turned out, Sakura Tohsaka's worries were unfounded.

Although we've done this many times before at the sports storage area.

Even at this moment, Ian maintained a level of activity that was almost identical to before.

No.

Or rather, it was even more powerful than before.

Rin Tohsaka watched her younger sister go from being grounded to merely skimming the surface of the water, and finally ascending to the void.

Her expression was so one of pure enjoyment that she seemed completely unbothered by her sister's live viewing.

The girl's magical circuits thus formed direct connections with her servant time and time again in the air.

The connection between the two also strengthened during this process.

finally--

As the girl tilted her head back towards the sky, this thrilling performance came to an end.

of course.

Rin Tohsaka also "received" a gift from her sister—the spray of water that she gushed out due to her excessive excitement.

"Yes, sorry."

Sakura Tohsaka turned her face away, her tone full of shame.

At this moment, her body was held tightly in Ian's hands, like a package that had just been retrieved, her legs straight up, higher than her ears.

The point used to create the connection trembled slightly, and something was dripping out continuously.

"Sister... I didn't mean to."

"I know." Rin Tohsaka, looking embarrassed, took out a handkerchief and wiped the liquid from her sister's face.

"Your sister doesn't blame you."

"but--"

"Sakura." Rin Tohsaka, now clean and tidy, looked at Sakura Tohsaka and Ian in front of her.

"Are you guys really that excited? Are you really that thrilled?!"

Sakura Tohsaka could understand this behavior, but she still felt it was a bit too exaggerated.

“Hmm… there are some.” Sakura Tohsaka tilted her head back and looked at Ian, who was hugging her.

The latter quickly understood and lowered his head to kiss her—this small gesture alone excited the girl once again.

Seeing this, Rin Tohsaka realized that if things continued like this, she would have to watch them do it again, so she quickly spoke up to stop them.

"okay!"

"I understand! Sakura, you don't need to demonstrate anymore—I don't want to get sprayed all over my face again!"

Perhaps it was Rin Tohsaka's words that had an effect, or perhaps Sakura Tohsaka truly felt that it should end there.

She quickly ended her kiss with Ian and gestured for him to put her down.

After tidying up her clothes, Sakura Tohsaka walked up to her older sister.

"Sister, thank you."

"Thank you for finding such a suitable place for me and Mr. Ian."

"Nothing."

Rin Tohsaka felt a little embarrassed—she felt it was a bit strange to provide a venue for her sister and her Servant to have intimate contact.

of course.

It's only "a little" at that.

She didn't object to Sakura Tohsaka and Ian doing this—after all, it was in line with her mother's original intentions.

“We’re all sisters.” Rin Tohsaka shrugged. “You don’t need to hold it against me.”

However, upon hearing this, Sakura Tohsaka shook her head.

"elder sister."

"That being said—you did me a great favor."

"Necessary compensation is still necessary."

"Really, it's not necessary!" Rin Tohsaka waved her hand in refusal. "There's no need to repay me!"

"Of course!"

Sakura Tohsaka grabbed Rin Tohsaka's hand.

Her face was flushed, clearly indicating that she hadn't fully recovered from her intimate moments with Ian.

"My sister's actions are very meaningful to me."

"..."

Feeling that her younger sister had an inexplicable obsession with this kind of thing, Rin Tohsaka, unable to persuade her otherwise, had to give in a little.

"alright."
