Oberon went to find Shirou Emiya and King Arthur, and Izawa Sugi turned around and entered the Matou mansion.

They are not children anymore, nor are they high school DKs who need to be carried to the toilet by hand. Ize Shan has reminded them all that he should have, and let Oberon do the rest. Anyway, the worst result is that he will just shatter into pieces.

Izawa Sugi sensed that Tosaka Rin was in a room on the third floor. He came to the door and knocked: "Rin?"

"Archer? Come in." Tosaka Rin's voice came out.

Pushing the door open, Ize Shan took a quick look around.

This should be Matou Sakura's room in the Matou family. The room is clean and tidy. There are many magic books on the bookshelf. There is a closet behind the bed and a set of tables and chairs next to the bookshelf. There is nothing else. It doesn't look like the room of a fifteen-year-old girl at all.

Tosaka Rin put Matou Sakura on the bed, and when Izawa Sugi came in, the girl was pushing the bed hard.

After Tosaka Rin pushed the bed to the center of the room, she took a deep breath and looked at Izawa Sugi: "I just gave Sakura a basic checkup. Archer, you should come and take a look too."

As she said this, she made a warning gesture.

Izawa Sugi understood that it seemed that Tosaka Rin did not intend to keep Matou Ruoyan overnight, so he prepared to take action.

Ize Shan nodded: "Let me see."

Izawa Sugi folded his hands and placed them on Matou Sakura's chest, and the gentle power penetrated into the girl's body. Izawa Sugi's expression remained unchanged, but he sighed slightly in his heart.

It's too late. Eleven years have passed and the Mark Bug has long become a part of the girl's magical mark. If it is removed abruptly, Sakura Matou will die immediately.

He looked up at Tosaka Rin beside him, the patterns in his eyes spun, and the next second, Izawa Sugi and Tosaka Rin entered the illusion world.

Tosaka Rin: “…Huh?”

Nothing seemed to be changing, but the girl's intuition as a magician told her that she was in a very dangerous situation.

In the dream, Izawa Sugi called out to Tosaka Rin: "Rin, I set up an illusion. There is a time difference between the illusion and reality. When we finish talking and return to reality, only one second will have passed. It will not attract the attention of Matou Ruoyan."

Tosaka Rin was shocked: "Illusion? Illusion? So powerful..."

She looked around and finally found something different from the real world.

There was moonlight streaming in through the window, but it was not the silver moonlight in reality, but scarlet.

Ize Shan said: "Let's get down to business. Although I have no intention of hurting you, you have stayed in the illusion for too long and it will still have an impact on you."

He looked at Tosaka Rin seriously, "I sensed the presence of another soul. The Matou Ruoyan is located in Matou Sakura's heart. What are you going to do?"

Rin Tosaka's eyes were filled with anger. She tried to speak calmly, "No matter how powerful Matou Rukan is, he is now a Crest Bug, a part of Sakura's magic crest. He transformed Sakura into a water-type, which means..."

Tosaka Rin smiled, even though there was no smile in her eyes. "It's a situation that I can analyze and interfere with."

Izawa Shan raised his eyebrows and asked with interest: "Oh? I'd like to hear the details."

"My teacher once said that most magicians only have one attribute, and those with two attributes are considered geniuses. I have five. It just so happens that the magic of the Tosaka family is to make magic flow, accumulate, and transform. This means that I can transform magic into any attribute and use magic of almost all attributes. There are countless directions for development."

Tosaka Rin thought of something and a gentle and nostalgic smile appeared on her face.

"But let's not talk about ancient magic, the accumulation of magic of a single attribute in modern magic alone is as vast as the ocean. If I want to become a magician proficient in all types, I'm afraid I won't be able to achieve it in this lifetime."

"But on the other hand, I don't need to be proficient in every type of magic, as long as I can crack it by brute force."

Tosaka Rin's tone was full of eagerness and excitement.

"I can interfere with almost all magic and make it ineffective. As for the rest..."

She clenched her fist and raised it in a fist pumping gesture.

"Just beat the other person up."

Although she was very depressed, Tosaka Rin was still very grateful for the Bajiquan class arranged by Kotomine Kirei, which made her life in the Clock Tower much easier.

"I have brought all the A-level gems that I have stored up over the years. I plan to set up an interference magic formation on Sakura, so that Matou Ruoyan's magic will be ineffective."

Before taking action, Rin Tosaka had already thought of a plan.

"Although Sakura has been transformed into a water attribute, her original virtual attribute has not disappeared, but has lost its development value and possibility. In this way, although Sakura cannot use magic, interfering with magic formations will not bring any physical burden to Sakura."

As for how to completely remove the Matou Dirty Inkstone... Tosaka Rin plans to take Matou Sakura to the Clock Tower after the Holy Grail War is over to seek help from El-Melloi II.

Anyway, the El-Melloi family owed a huge amount of foreign debt and was short of money. Tosaka Rin felt that giving the Matou family's savings to the El-Melloi family would be enough for the future teacher El-Melloi II to solve the remaining problems of his sister Matou Sakura.

Tosaka Rin looked at Izawa Sugi with burning eyes, "But while I'm setting up the magic formation, if Matou gets caught and endangers Sakura, it will be troublesome, so Archer, I'm counting on you."

Ize Shan couldn't help laughing.

Tosaka Rin really works harder than he thought.

And Tosaka Rin does have enough ability to support her to do so, she is so beautiful and dazzling.

Izawa Sugi was in a very good mood: "Can you show me your magic array? Actually, sealing conscious energy bodies in the body is my specialty."

Sealing Matou Rukan as the Tailed Beast really shows respect for him.

Izawa Shan promoted himself: "The effect of my sealing array is very good. Not only can it block the other party's perception of the outside world, but it can also continuously absorb the power of the sealed consciousness. If you think it is appropriate, we can do both at the same time."

After hearing this, Tosaka Rin's eyes widened slightly. She felt a little embarrassed and her cheeks turned red.

"…Thank you, Archer."

”

You're welcome. I can only say that you have a strong elder sister power, and I like people like you."

Izawa Sugi smiled and touched the girl's head. "In order to protect her sister, Rin really works very hard. It's normal for people to want to help after seeing this."

Being praised like this, the girl with twin ponytails was a little surprised and a little embarrassed. She turned her face away subconsciously, tapped the ground with her toes uncomfortably, and stammered, "It's only natural for an elder sister to protect a younger sister. There's no need to praise me..."

The smile in Ize Shan's eyes deepened: "Yes, then let's discuss the formation diagram."

Izawa Sugi and Tosaka Rin communicated for a long time about the methods of embedding magic and sealing formations in the illusion, and finally reached a consensus.

"The effect of your sealing formation is too advanced. I don't want Sakura and Matou Ruoyan to have any communication at all. It's better to force Ruoyan's Crest Bug to hibernate."

Tosaka Rin carefully memorized the part of the Tailed Beast Sealing Formation that Izawa Sugi brought out, "I will record the Rotation Intervention Technique first, and during this time you will simultaneously use the magic technique called Diamond Seal to suppress the Dirty Amulet, and then use the Eight Diagrams Seal to extract the Dirty Amulet's soul power for Sakura to use."

Tosaka Rin closed her eyes, and after making sure she remembered to leave a gap for Izawa Sugi to perform the seal, she opened her eyes and said, "We can start now!"

Ize Shan raised his hands and made a seal: "Release!"

The next second, Izawa Sugi and Tosaka Rin returned to reality at the same time.

Izawa Sugi didn't feel anything, but Tosaka Rin's eyes went dark and she almost fell down. She was originally holding onto the bed railing, but after the illusion was lifted, she fell directly on Matou Sakura.

"Rin?"

Izawa Sugi was still checking Matou Sakura's body with his hands folded, but Tosaka Rin suddenly fell over and he had to quickly let go of his hands.

Tosaka Rin calmed herself down and stood up again after the dizziness wore off, a look of fatigue still fittingly on her face.

"…I'm fine, just a little tired."

Izawa Sugi: “…”

In order to trick Matou into dirtying the inkstone, Tosaka Rin really tried her best.

Tosaka Rin took out a handful of gems and said, "Sakura is lacking in magic power. I will set up a magic absorption formation to help her recover."

In fact, Tosaka Rin immediately began to construct interference magic.

Although Tosaka Rin can directly use projection to strengthen the mimic gem, which is economical and affordable, but since it is going to work on her sister, of course she can't use such a cheap method.

Tosaka Rin held her breath and carefully arranged the formation, then she took a step forward.

"Anfang——!"

The magic seal was activated, and the magic seal on the girl's left hand began to glow with an icy green light.

"Five elements—spin! Spin! Spin!"

"Reverse the disc! Internal interference!"

The five directions centered on Matou Sakura were lit up, the gems glowed brightly, forming a rotating disk, and magic power flowed and rotated between the gems, forming a pentagram.

The next second, a shrill scream was heard.

"Damn it! The little girl from the Tosaka family!"

That was the sound of Matou's dirty inkstone.

Matou Sakura, who had originally closed her eyes, suddenly opened them. The bottom of her eyes were black and her pupils were yellow, as if she had been invaded by some monster.

The girl sat up suddenly, as if she was going to hurt someone.

But at this moment, there was a clinking sound of chains.

"Diamond Block!"

Sixteen chains spread out, forming a huge sealing formation.

The moment the formation was formed, the girl's body froze, and the roar of Matou Ruoyan echoed in the room: "No! No——!"

Matou Sakura's eyes changed from yellow eyes with a black background to lifeless light purple. After several changes, they finally returned to light purple. She fell weakly on the bed.

When Izawa Sugi saw that Matou Rukan's consciousness was suppressed, he immediately changed his formation.

"Gossip Blockade!"

Two overlapping Four Symbols Seals were driven into the girl's heart, and the black seal rune disappeared under the skin. Then Izawa Sugi performed another spell, and at the same time, the magatama in his eyes spun at high speed, and he began to reinforce the seal at the level of the Tailed Beast.

The light of the pentagram dimmed, and with a click, the gem shattered. The magic power accumulated inside had entered into Matou Sakura's body in the form of a formation. At the same time, the seal was set, and the unlucky Matou Dirty Ink was permanently sealed in the small dark room.

"Okay, I left a gap for power to pass through, but I closed the channel for consciousness communication."

Ize Shan loosened his hands, and the chains slowly dissipated. He looked at the girl whose aura had become purer, and nodded with satisfaction.

"The seal and formation are constructed very firmly, perfectly!"

Tosaka Rin panted slightly, she took a step forward, touched her sister's cheek, smiled happily, and then she made up her mind.

Tosaka Rin pushed the bed back to the wall, set up a defensive formation, and looked at Izawa Sugi.

"Archer, thank you for your hard work. Although I should say goodnight, but..."

Tosaka Rin took a deep breath and said, "I want to talk to you."

Izawa Sugi looked at Tosaka Rin in surprise.

"What?"

Tosaka Rin and Izawa Sugi left Matou Sakura's room and returned to the first floor living room of the Matou mansion.

The girl sat on the sofa, looking a little embarrassed.

"…Archer, regarding the Holy Grail War, I feel it is necessary to tell you some information that only the Yusan family knows."

Among them was the information left by her father, Tosaka Tokiomi, and also the news she had heard from Illya.

"The Holy Grail War is essentially a ritual constructed by the Einzbern, Matou, and Tosaka families. The ultimate goal of the three families is to open a hole to the root through the Holy Grail."

Tosaka Rin intertwined her fingers and looked serious. "The most important part of this ceremony is not the Lord, but the Servant. The soul and magic power of the defeated Servant will be used as firewood to activate the Holy Grail. The Command Seal in the Lord's hand is used by the final winner to order the Servant to commit suicide."
