Strategic Relocation

The Older Sister servant still wore the blindfold, but on the surface of the blindfold were two simple line drawings of "eyes" drawn with black and red dye. However, the pupils of those "eyes" seemed to be alive and would move back and forth, as if they were really "looking" at something.

"Rin, Jizi, get out of the way!"

Saber rushed to the door with a shout, her invisible sword swirling in the rapidly rotating air currents. She held the sword horizontally in front of her, cautiously guarding against the enemy.

"Saber! By the way, your Noble Phantasm can control hurricanes."

"Okay, once the barrier is broken, I'll blow away the Black Mist at the entrance, and Archer, you can take the opportunity to shoot her, is that alright?"

"Leave it to me!"

Archer nodded, conjured his usual bow, nocked an arrow, strung it, and aimed at the Older Sister servant's forehead.

The Older Sister servant had lost her mind. Even though the enemy was discussing tactics right in front of her, she didn't react at all and just tried to smash the barrier open.

Duang!

By this time, Jizi and Lin had already left the doorway. Without their magical support, the barrier was no more solid than a piece of paper in front of the servants strengthened by the Black Mist, and it shattered in less than a second.

"Now's the time—[Strike Air]!"

A fierce wind swept from the tip of Saber's sword, blowing away all the Black Mist that was spreading into the room without any obstruction. Even the Black Mist in the courtyard was shaken back and forth by the violent air movement and became thinner.

The Older Sister servant was blown backward by the sudden gust of wind and had to use the chain to hook onto the door frame to steady herself, but by then the archer's arrow had already been fired.

"Here you go!"

The arrow exploded upon contact with the enemy. Rin knew this attack could even tear apart a Berserker's body, and naturally assumed the female Servant would be defeated. However—

"Ugh... Ahhhhhh!"

As the smoke from the explosion cleared, the Older Sister servant was seen standing, blood streaming from her head. For the first time, she uttered a sound—a piercing scream, like the final curse of a vengeful spirit who had died unjustly, burdened with countless grievances. The very sound sent chills down the spines of everyone present. Simultaneously, Black Mist seeped from her seven orifices.

"Jizi, magic!"

Rin reached out and grasped Jizi's hand. The connection between them wasn't just physical; their Magic Circuits were linked at that moment, and Jizi's magical energy flowed continuously into Rin through the link. This was another coordinated plan that Rin and Jizi had practiced for a long time. The principle was to use the Tohsaka Family's expertise in storage and transformation Magecraft, applying this technique, originally used for Gems, to Jizi —in layman's terms, treating Jizi as a high-capacity, mobile, self-propelled Gems. Although her Magecraft skills were average, her body had an extremely high affinity for all forms of energy, hence this technique, used to deal with special situations where there wasn't enough time to take out Gems or when the number of Gems was insufficient.

Skipping the step of accumulating power, Rin directly unleashed a massive amount of magical energy and then chanted the incantation:

"Hayate!" (①)

A strong wind rose again, though not as powerful as Saber's Noble Phantasm attack, it still had the force of a small tornado, continuously blowing away the Black Mist.

"Saber, fight outside! I'll cover you!"

"Learn!"

The cramped indoor space is disadvantageous to both Saber and Archer. Although the opponent will face the same disadvantage, a larger space would be more convenient if she were to launch a reckless and indiscriminate attack when she loses her mind.

"Drink it!"

Saber's greatsword slashed towards her opponent's abdomen, but the latter used chains to wrap around the sword and then threw one end of the dagger toward Saber's face. Saber, however, did not dodge at all, but instead twisted her waist to assist in the momentum, swinging the sword forward. The chains binding it and the servant holding the chains were also pulled along, and they fell heavily into the courtyard.

As for the flying dagger, it was blocked by a slender object that suddenly appeared in front of Saber and flashed with light when it hit her, so it did not cause any damage.

In the courtyard, Rin continuously used air Magecraft to create airflow and barriers, driving all the Black Mist into a corner. Although this increased the concentration of the Black Mist, it also allowed them to move around more freely.

"Saber, can you win her over?"

"It's not a big problem, but it will take some time."

The Older Sister servant's power was forcibly increased by several levels, but since Saber had made this judgment, Rin chose to trust her, and thus ordered Archer, who wanted to help, to:

"Then, Archer, go and keep watch around. With such a commotion, even if others don't notice, the Caster from Ryuudou Temple will definitely take notice."

"Receive."

Archer leaped onto the rooftop and then disappeared from sight with several more leaps. Meanwhile, Saber and the Older Sister Servant had already exchanged more than a dozen blows. In terms of strength and skill, Saber held a clear advantage. However, the enemy's irrational and reckless attitude, along with the Black Mist emanating from her body, made Saber very wary.

Unlike Berserkers who become incredibly agile even Mad Enhancement (regardless of which Berserker), the Older Sister Servant's fighting style is currently unpredictable and even more troublesome. Since Archer's headshot hadn't killed her, Saber realized that without unleashing her true Noble Phantasm, a one-hit kill was impossible. Although she had countless opportunities to severely injure her opponent, it was only because her opponent had completely abandoned defense and focused solely on attacking. This trade-off of injury was not what Saber wanted.

"Looks like I'll have to use it just one more time..."

Unable to resolve the situation after half a day, Saber was starting to get impatient. It was early morning, not night, and the longer the battle dragged on, the more unnecessary attention it would attract. After weighing her options, she decided that she had no choice but to use her trump card once more.

"What a pity, having to launch [Avalon] twice when dealing with such a dishonorable opponent."

Having made her decision, Saber deliberately created an opening, and the aggressive Older Sister, as expected, didn't miss the opportunity. She charged straight at Saber, daggers in hand, aiming for Saber's neck. Saber ignored her, raising her hands above her head, ready to bring her sword down.

"[Avalon]!"

As Saber shouted, golden holy light shone from her body, and a semi-transparent scabbard gradually appeared. When the Older Sister servant's dagger struck Saber, it was as if it had sunk into a lake, creating ripples in the space, but it did not touch Saber at all.

Then Saber didn't stop, her sword slashing down towards the top of the Older Sister servant's head.

"We got it!"

"Wait, watch out, Saber!"

There was indeed a tangible feeling of being hit, but at that moment, a large amount of Black Mist rose from the opponent's seven orifices and even the pores of his skin. The high concentration of Black Mist seemed to have materialized, blocking Saber's blade and instead winding around Saber along the sword.

"[Avalon]!"

Saber roared again, and the golden holy light shone brightly once more. The Black Mist vanished the moment it touched the golden light.

Looking at the Older Sister servant, the Black Mist seemed to represent all the filth within her body. After being dissipated by the light of Saber 'Noble Phantasm, the eyes on her eyepatch disappeared, and she collapsed to the ground as if she had lost all support.

"This is..."

The code of Knight prevented Saber from attacking an enemy who was unable to retaliate. She sheathed her sword and looked at the other three.

"What should we do, Master?"

"You ask me... I'm also Tohsaka, what do you think?"

"Hmm," although the Older Sister servant had collapsed, the Black Mist from before was still there. Rin created an air barrier the size of a basketball to compress and collect it all, and replied, "In short, I can't attend class today, and I probably can't stay here either."

"Sigh, why?"

"Because we've been targeted by an unknown enemy," Jizi explained to Shirou on Rin's behalf. "If they can sneak into our house at night and tamper with the prisoners, they could easily sneak in and assassinate us too."

"Oh... that's true."

"It was my dereliction of duty," Saber said gravely, "I was so focused on guarding the mansion that I neglected the Workshop and the prisoners."

"Don't blame yourself, after all, the enemy is lurking in the shadows." Rin comforted Saber, then continued in a decisive manner, "Anyway, let's move on first, while it's daytime and others can't easily take action."

But where to go?

"My home," Rin said calmly, "Is protected by a more comprehensive barrier set up at the Tohsaka Residence, making it easier to guard against. Moreover, its location is more remote, so even if a battle breaks out, it won't involve unrelated personnel."

"Should I go too?" Shirou was still a little embarrassed when he heard that he was going to a girl's house.

"Of course, or do you think it's safer for you to stay here alone?"

"No, but if that happens, Fuji-nee and Sakura..."

"We'll figure out how to explain that later," Jizi said. "Right now, staying away from them will be the best way to protect them."

"Sigh, that's true..."

Having convinced Shirou, the plan to relocate the base was immediately put into action. Rin used disguise Magecraft to conceal the figure of the Older Sister servant, had Saber carry her, and Jizi and Shirou each carried a bag with some necessities. Then they moved towards the Tohsaka Residence. Because it was daytime, the journey was uneventful. Upon arriving at the Tohsaka Residence, Rin and Jizi busied themselves setting up various barriers and traps around the entire mansion, Shirou and Saber trained in the courtyard. The captives were locked in a targeted seal that Rin had set up by analyzing the Black Mist samples she had collected. Archer was sent to monitor Ryuudou Temple. The day passed quickly.

Today's original plan was completely disrupted by what happened this morning, but the overall strategy was sound. After dinner, we discussed it and decided to continue with the original plan tomorrow. To conserve energy, everyone went to bed early.

"Then, Emiya- kun, you can use Jizi's usual room. Jizi will sleep with me."

"Oh well."

"Huh!? Rin and I are together--"

Shirou thought there was nothing wrong with Rin's bedroom arrangements, but Jizi suddenly blushed.

"What's wrong? Is something the problem?"

"No, no, no, it's nothing, let's leave it at that."

It's not a big deal for two close girls to sleep together, but the relationship between Rin and Jizi is more than that. I don't know if she genuinely didn't care or if she was doing it on purpose.

Lying together in bed, Jizi felt the warmth and breath of the person next to her and couldn't fall asleep peacefully. After tossing and turning several times, Rin finally asked:

"What's wrong? Can't you sleep?"

"Um..."

Is something bothering you?

"... a little."

Tell me about it?

"... Rin, what exactly is your relationship with [assassin]?"

"Uh..." Rin Tohsaka sister, looked troubled after hearing the question.

P. S. 1. I didn't finish playing it; I just suddenly had an idea... This was rushed, so the quality is so-so. Just take a look...
