When Izawa Sugi's original body was fighting Cu Chulainn, his two incarnations brought Tosaka Rin to Miyama Town.

Fuyuki City is divided into old and new parts, with the Tsurumi River as the dividing line.

The new city area is called Xindu. It has various advanced facilities and large shopping malls. It is a place where young people like to play and shop.

The link between the old and new areas is a bridge that crosses the Tsurumi River.

The Fuyuki City Bridge is bright red in color, with steel bars on both sides fixing the bridge. During the Fourth Holy Grail War, many Servants fought on this bridge.

The area near Enzoyama is the old town, where Miyama-cho is located, and the residences of Tosaka and Matou are also located.

Traveling along the undulating road, Izawa Sugi and Tosaka Rin soon arrived at the scene of the accident reported in the news.

Standing on the roof of a building, Tosaka Rin looked far ahead at the community built against the mountain, her face darkening.

"What a brilliant barrier! If you don't get close and observe carefully, you can't tell from a distance that this is a magician's workshop."

In order to prevent earthquakes, the houses on a street are basically built in townhouses. In Tosaka Rin's eyes, all the townhouses on the street at the foot of the mountain are included in a certain magic formation. In other words, that community is Caster's magic workshop.

Izawa Sugi observed for a while and pointed to a building in the distance: "That should be the core of the formation."

Tosaka Rin looked in that direction: "Oh? Isn't this the haunted mansion where ghosts are said to appear?"

There is a three-story Western-style building behind the townhouse.

Tosaka Rin crossed her arms and thought, "That's a famous haunted house in town. I remember when I was a kid, there was an organization in school that came here to test their courage. Now it's winter, and no one will go to a room that has been vacant for many years to mess around. It's indeed a suitable place for a magician to hide."

Izawa Sugi suddenly took out a fox disaster relief mask and put it on his face.

Tosaka Rin was stunned: "What's wrong?"

The next second, she also noticed the line of sight, and looked over there, only to see Shirou Emiya looking over here in front of a townhouse not far away.

King Saber Arthur, who was following the boy, was slightly ahead. Apparently, he was the first to spot Tosaka Rin and Izawa Sugi on the top of the tall building.

Tosaka Rin was silent.

She looked carefully at Saber beside Shirou Emiya, and after a while she murmured, "Oh my God, King Arthur is actually a man..."

The Servant summoned by Shirou Emiya is still Saber, but it is not the King Arthur she knows at all!

Surprisingly, this is a handsome guy who looks like a prince charming. This, this, this...

Izawa Shan's mouth twitched, pretending not to understand: "Ah? Lin, what did you say? King Arthur is of course a man."

Tosaka Rin immediately raised her hand to cover her mouth and looked away: "Uh, no, nothing."

No, that’s weird, let me take another look.

Tosaka Rin went to see Saber King Arthur again, and kept comparing him with the Artoria Pendragon she knew.

The young King Arthur was wearing a blue and silver armor, and still holding the sword of victory whose length and shape could not be seen. He seemed to be taller than the female King Arthur and felt more secure.

King Arthur looked at her with a clear and pure look, his lake green eyes were full of calmness and fighting spirit. He had an extraordinary aura and strength that was accumulated but not released. Both his demeanor and bearing were worthy of the name King Arthur.

Tosaka Rin's expression was a little subtle.

Well, she has always wanted to summon Saber, but the Servant she summoned every time was Archer.

Izawa Sugi saw this idea and couldn't help but roll his eyes.

At this moment, Tosaka Rin suddenly remembered something and she suddenly looked at Izawa Sugi.

"Come to think of it, why did you suddenly put on a mask? It doesn't matter if Saber sees you, right? Do you know each other?"

Wow! Is Archer also a hero from the time of King Arthur? But an archer with a chain? There doesn't seem to be such a knight in the legend?

Izawa Shan chuckled and made a snorting gesture: "Well, this is a secret."

Tosaka Rin curled her lips: "You guys have too many secrets, don't you? I still don't know your real name."

Izawa Sugi smiled and said, "As long as I can bring you victory, that's enough."

He deliberately asked, "Why are you suddenly talking about King Arthur? Could it be that the Saber below is King Arthur? Lin, do you know him?"

Tosaka Rin said calmly: "It's just that some of the information about the Fourth Holy Grail War recorded by my father is somewhat similar. I speculate that he may be King Arthur."

Izawa Sugi glanced at Tosaka Rin, and considering that the girl had successfully lied, he didn't ask any more questions.

He asked, “What are you going to do next?”

"What? Since we are here, we should investigate."

Tosaka Rin's eyes became serious, and she jumped up without hesitation.

Shirou Emiya, who saw this scene from a distance, subconsciously shouted, "Tosaka! You!"

Arthur said softly, "It's okay, Shirou, she has a Servant with her."

Just as King Arthur said, when Tosaka Rin was about to fall to the ground, Izawa Sugi appeared, easily took away the force on the girl, and at the same time jumped lightly, holding the girl and falling to the ground.

Tosaka Rin stood on the ground. She took a step forward, looked at Shirou Emiya, and said with a smile, "Good night, Emiya-san."

Arthur looked at Ize Shan warily. Silver armor appeared, a blue skirt armor covered his body, and both hands grasped the Invisible Sword.

Shirou Emiya groaned, feeling a little overwhelmed.

"Tosaka-san, why are you here?"

Tosaka Rin ignored Arthur's alertness. She raised her chin slightly and said indifferently, "Of course I'm here to check Caster's magic workshop. Tosaka has always been the magic manager of Fuyuki City. I will not allow any magician to break the rules and attack ordinary people!"

After hearing this, Shirou Emiya felt relieved and a smile appeared on his face unconsciously.

"Did Tosaka-san come here because he saw the news?"

Didn't he beat him? Great!

Tosaka Rin did not mention the news from Rider. She said, "You don't need to worry about that. But you, Emiya-san, are you here to defeat Caster?"

Shirou Emiya said seriously, "Yes, Caster actually dragged ordinary people into this, it's really too much!"

Tosaka Rin was silent for a moment. Emiya Shirou was really as kind as she remembered.

"...It's really ironic for an ordinary person like you to say this, who was dragged into the Holy Grail War."

She suddenly asked Shirou Emiya: "Miya-san, although you were dragged into this by accident, why didn't you quit? I never knew you were a magician before. From your performance at school that day, you seemed to have no idea about the Holy Grail War at all. So why didn't you give up?"

Shirou Emiya shook his head: "You asked this suddenly... Actually, I wanted to quit at first. Although I summoned the servant, I had no idea what to do, but..."

He asked Tosaka Rin, "Tosaka-san, you said that the Tosaka family is the family that manages Fuyuki City, so do you know about the fire ten years ago?"

Tosaka Rin's expression was sad and confused for a moment.

She thought of Shirou Emiya, whom she once knew.

"...Of course I know. It was caused by the Fourth Holy Grail War."

“I am a survivor of that disaster.”

Shirou Emiya's eyes were pure and firm: "The Holy Grail War has begun again. Although I don't know what I can do, I want to prevent such a tragedy from happening again. This is why I didn't quit."

Tosaka Rin looked at Emiya Shirou quietly. After a long time, she suddenly turned her head, and her double ponytails swung in the air in beautiful arcs.

She crossed her arms and said, "I really can't help it. I've lost to you. So let's catch up."

Tosaka Rin reminded Shirou Emiya again: "Since you have joined in, you must be prepared to die in battle."

Shirou Emiya was delighted at first, then he responded, "Wait, what does catching up mean...?"

"Idiot, you don't think the enemy is here, do you?" Tosaka Rin said unhappily, "These are just a trick, Caster's real magic workshop is in the back."

Izawa Sugi made a gesture of throwing his arms towards the alert King Arthur and followed Tosaka Rin.

Arthur blinked and looked at Shirou Emiya: "Shirou, should we follow?"

Shirou Emiya: "There's nothing we can do now. Let's just follow Tosaka-san."

Four people stood in front of the Phantom Mansion. The tall iron gate was tightly closed, and scarlet magic runes were faintly visible around it.

Izawa Shan took a step forward, he stretched out his hand and tentatively touched the ritual rune, his palm seemed to be submerged in water, and dark purple mist began to fill the air.

At this moment, a huge and complex circular rune appeared at the gate, and then purple arcs flashed on Izawa Shan's body. A pattern flashed on the back of his hand, and Izawa Shan immediately withdrew his hand and stepped back.

If he didn't leave, his two clones would be shattered by Caster.

"…How's it going, Archer?"

Tosaka Rin raised one hand and prepared to attack.

Izawa Sugi looked at his hands, then at the huge purple rune in front of him, and whispered, "It's Age of Gods magic. Caster is a Age of Gods magician."

After hearing this, Tosaka Rin felt relieved.

According to the information she cleared from Kotomine Kirei, Caster is the legendary traitorous witch Medea, she is the Magician of the Age of Gods!

Great, Caster is still the one she knows!

But unfortunately, the information she knew about Caster was basically zero!

Because Matou Sakura said that Matou Ranyan used Kuzuki Soichiro to threaten Caster and took the opportunity to kill Caster, he has never confronted Caster head-on.

In other words, Tosaka Rin has no idea about Caster's abilities and Noble Phantasms!

So sad.

Tosaka Rin asked Izawa Sugi: "Is there any way to break through?" Izawa Sugi shook his head and nodded: "If I am given enough time, I can analyze Caster's technique, but the longer the time is delayed, the more people will be implicated, and secondly..."

He said helplessly: "I am not a Caster, so my power is suppressed to a certain extent, and I cannot compete with the magicians of the Age of Gods for the right to control the land."

Compared to being called father by King Arthur who was watching him, beating Caster was not enough to make him decide to transform into King Uther.

Tosaka Rin had a headache: "Is it possible that we can only attack head-on?"

Izawa Sugi: “Not really.”

Tosaka Rin glared at Izawa Sugi: "Don't talk nonsense! Say it all at once."

Izawa Sugi looked at Arthur and said to Tosaka Rin with a smile: "Rin, I think it would be more appropriate to reach an agreement with Saber first instead of studying Caster's magic, right?"

Did Arthur discover something? He felt that the other person's eyes were cold.
