"So, what are we going to do?" Emiya Shirou asked with some confusion.

"There's only one way now." Rin Tosaka looked up at Emiya Shirou and said in a solemn voice.

Knowing that Rin Tosaka still had something to say, Shirou Emiya looked back at Rin Tosaka waiting for her next. Sure enough, the next moment, I heard Rin Tosaka continue, "Go find Illyasfil who owns Berserker. Feng. Einzbelen. Now only she can help us. ”

After that, things were simple, and Rin Tosaka and Shirou Emiya, who were thinking about Archer and Saber, didn't care if there were still classes that day, and after eating a breakfast prepared by Shirou Emiya, they left home and took a taxi to the forest where Einzbergenburg was located.

Dozens of minutes later, the two arrived at the forest on the outskirts of Fuyuki, paid for the car and walked down, moving along a path that was faintly walked out towards the depths of the forest. After another moment, Rin Tosaka suddenly stopped, pointed ahead and said, "Emiya, can you go forward first?" ”

"Yes." Although Emiya Shirou was a little unclear, his character as a good old man still made him agree, and he set off in front of Rin Tosaka, and then suddenly exclaimed, as if he had been electrocuted, and jumped back to the same place.

"Huh."

"Sure enough, the entire forest is under the management of the other party." Seeing this, Rin Tosaka said in a tone that was really like this.

"Isn't that like hitting an alarm bell?" Emiya Shirou was shocked when he heard this, turned his head to look at Rin Tosaka and said in a continuous voice.

"Nothing wrong, right? We are not here for the surprise attack, but for talking, and it is better to report our intentions. Rin Tosaka said indifferently.

"I see." Emiya Shirou suddenly let go of the worries in his heart. Then Rin Tosaka, who was on the side, stepped forward again, and walked gracefully to the place where Emiya Shirou had stepped on.

"You'd better be careful. I'm still a little numb now. Seeing this, Emiya Shirou reminded with some concern.

It was only before the words fell, and an explosion suddenly sounded.

"Boom!" Immediately, Rin Tosaka, who bore the brunt of the attack, was lifted away and fell heavily to the ground more than a meter away, smashing up a faint cloud of dust.

"How dare you do it, that little ghost!" Rin Tosaka stepped forward and shouted loudly as she glared ahead.

Although he was embarrassed by Illya's arrangement, Rin Tosaka decided to endure it for the sake of the goal in his heart. So, after yelling and venting, he set out again with Emiya Shirou and walked along the mountain road towards Einzbergerburg, which was located deep in the forest.

Along the way, Rin Tosaka can be described as 'trekking through mountains and rivers', and after going through hardships, it finally took about half a day to see the huge castle full of Western classical style - Einz Bellenburg.

"It's here. Let's go down. Rin Tosaka said. After saying that, he jumped onto the fault and walked towards Einz Bellenburg.

It's the same with Emiya Shirou. So after another moment. The two entered the courtyard of Einzbergberg. After a few steps, he came across two beautiful women wearing white nun-like robes and hats, with only their hands and faces exposed, and they looked almost identical.

At this time, I only heard the woman with her hair exposed in her ears leaning down slightly. He said expressionlessly, "The eldest lady has been waiting inside for a long time, please come with me." ”

"I'm sorry for you." At the same time, Rin Tosaka also showed due upbringing. Then, together with Emiya Shirou, he walked into the huge Einz Bellenburg with two women in white. After turning around three times and two times, I came to an empty room with warm tones, and saw that I was sitting at a small round table. With her eyes closed, Illya looks like an ancient European aristocratic lady sipping black tea.

"You two may be seated." Serra, the woman in white with no hair in her ears, walked to the round table and pointed to a chair beside her. As for the other person, Lijielit spontaneously stepped aside and stood behind Illya, looking like a guard maid.

In response, Emiya Shirou and Rin Tosaka didn't say anything, and walked to the table and sat down opposite Illya.

"What a rarity, I didn't expect you two to come to me." Then Illya lightly put the teacup on the tray on the table in front of her, looked at Rin Tosaka and Emiya Shirou with a playful look and said, "Aren't you afraid that I will kill you?" ”

"Of course I'm afraid, but we have a reason to come." Rin Tosaka turned his head and glanced at Shirou Emiya next to him, then looked back at Illya Fell and sighed helplessly.

"Oh?" Illya was surprised, and her eyes stared at Rin Tosaka in surprise. In her understanding, Rin Tosaka, who is an enemy, should be very proud, why is he so decadent now? Rin Tosaka, who noticed Illya's gaze, did not hide it, and said very bluntly, "My Archer was taken away, and along with the spell, it was snatched by Caster. ”

After a pause, he added, "And so does his Saber." By now you should understand the seriousness of the matter. ”

"What!?" Illya was startled when she heard this, and looked at Emiya Shirou in amazement. Emiya Shirou nodded, his face full of helplessness and gloom.

“…… It's not that I don't believe it, it's that what you're saying is so unbelievable that I've never heard of a Caster being able to take over the spells of other Masters and control of the Servants. Even Caster is a magician. After a moment of silence, Illya questioned with a slight frown.

"It probably has something to do with Caster's identity." Rin Tosaka thought for a moment and said.

"Identity? Do you know who Caster is? Illya asked.

"I don't know. But can you think of anything other than this reason? Rin Tosaka asked rhetorically. Illya couldn't help but be silent when she heard this, and then changed the subject, "Tell me what you know." ”

"We don't know much about the specific situation, except that we know that the leader of the other party is called Lin Yiyan, and there is a companion named Sakura, both of whom are powerful magicians, and they also have four Servants in their hands: Caster, Lancer, Archer and Saber, and I don't know anything more." Rin Tosaka sighed weakly.

But it's the opposite. Illya chuckled softly at the corners of her mouth.

"Four Servants...... Sure enough, it's a strong enemy. After a pause, he asked rhetorically, "You shouldn't have come here today just to tell me the news, right?" Say, what are your other purposes? ”

"We want to form an alliance with you." Rin Tosaka was shocked, and looked at Illya with burning eyes and said.

"Alliance? Why? You know, you're no longer a Master now, and I think there's anything you can do to help me. Illya stood up from her chair and walked around Rin Tosaka and Emiya Shirou with a sneering look in her eyes.

"We can help you hold Archer and Saber down while Berserker fights them." Rin Tosaka's expression remained unchanged and said in a solemn voice.

"Just you now?" Illya was skeptical. And she does have reason to be suspicious. After all, compared to Servant, even the most powerful magician can only barely fight against them, and if he wants to kill the other party, except for the magic dress that is similar to the magic ritual that Bazet mastered, which can be called a surviving treasure - the backlight sword, there is nothing that can help them, not to mention that the combat power of the real fight may not even be as good as himself, and even his own maid Lijielit is not as good as Rin Tosaka and Shirou Emiya.

"Yes." Rin Tosaka said confidently, "You know, before Archer and Saber were snatched by Caster, it was me and the Servant of the Emiya. Although we don't have anything to do with us anymore, there are some connections that can't be severed immediately, such as the relationship we once had with each other. Although it may not be effective, it can be used to delay Archer and Saber's actions. It should be fine for them not to join forces with Lancer and Caster in the first place. ”

"What's more, Caster, as a Servant, has a limit to his own magic power, so he wants to use the power of the spell and the contract to restrain the two Servants at the same time. It's not a simple thing for her and the Master behind her, and it also gives us room to operate, so our existence is not useless. ”

“…… Although my Berserker is the strongest. You don't need such a small trick at all, but since you have chosen to be the bait, I have no reason to shirk it. Well, I'll agree to an alliance with you for the time being. After a moment of silence, Illya, who looked at Rin Tosaka and Shirou Emiya, said arrogantly, "But if you die then, don't blame me for not saving you." ”

"Don't worry, this is our own choice, even if we die, we won't blame others." Rin Tosaka said proudly.

Emiya Shirou looked at Rin Tosaka beside him, and then at Illya opposite, feeling that he was completely superfluous, he smiled bitterly and acquiesced in this decision. Then Serra stepped forward again, leaving Illya's reception room with Rin Tosaka and Shirou Emiya, and heading to the rest of the castle, choosing her temporary residence.

As an alliance, in order to prepare for a surprise attack that may occur at any time, Rin Tosaka decided to take his own initiative and stay in Einzbergenburg for the time being. As for going to school on weekdays, in the face of the Holy Grail War, it's all a trivial matter, and there's really no need to get too tangled up.

………

"Serra, why haven't I received information about Caster's activities?" When Serra arranged for Rin Tosaka and Emiya Shirou to return to Illya's room, Illya asked with a very unhappy look.

"I'm so sorry, Miss, it was my mistake." Serra bowed her head and said apologetically.

"Actually snatched Saber, this kind of guy is absolutely unforgivable! Serra, immediately give me all the strength to search for the whereabouts of Caster and his master, Lin Yiyan, and I want to know all the information about them. Illya said hatefully.
