Tosaka Rin looked at the Command Seal in her hand suspiciously.

The connection between the Lord and the Servant was clear, but if she remembered correctly, the real Caster was a woman wearing a hood, right?

That woman has a master! Why did her Servant change from Archer to Caster?

For a moment, she didn't dare to ask the servant on the other end of the contract.

Tosaka Rin looked at the gems and dress in her hands. She first dealt with Matou Ruin, then rescued her sister, and then fought against Caster. She had almost used up all the things she had.

Oh, by the way, the unfortunate Shinji Matou is still in the Tosaka family. Although he is in a coma, he still needs to be fed some potions to prevent him from really starving to death.

Tsk, he is Sakura Matou's acknowledged brother after all.

Tosaka Rin thought for a while, suppressed the doubts in her heart, smiled and told her sister that she was going home to get some gems and would be back soon.

If the servant changes, she will be in trouble if she does not have the materials to cast the spell.

Matou Sakura had no doubts. She was now focused on saving those children, and even the matter of Emiya Shirou was put to the back of her mind.

The main reason was that she didn't dare to think that her sister really didn't like Shirou Emiya, and she was somewhat happy that she could continue to get along with Shirou Emiya.

Matou Sakura feels inferior and a little disgusted with herself for being like this.

Ah, my sister is so nice to me, I really hate myself for having such little thoughts. But if my sister really doesn't like the senior, then it won't be a big deal to wait a little, right?

Let's wait and see, Matou Sakura thought. She didn't want to compete with her sister who saved her. She would consider emotional issues after the Holy Grail War was over and the children's problems were resolved.

Just as Matou Sakura was concentrating on looking through the magic book, Oberon suddenly appeared beside her.

"Ying." He said calmly, "If someone asks you about me, just say you know nothing."

Matou Sakura was stunned. The girl was silent for a few seconds with a subtle expression.

“…Rider, what did you do?”

Oberon shrugged. "I didn't do anything. I just gave a psychologist a consultation to a guy who was a bit annoying, and he almost killed Shirou Emiya."

Matou Sakura looked at Oberon steadily and said softly, "...Rider, didn't I ask you to protect your senior?"

Oberon smiled and said nonchalantly, "He can't die. There seems to be something inside his body that is shining, like a fairy's treasure."

His smile slowly showed a hint of malice.

"Whether it's him or Saber, they always do something annoying at inappropriate times. I was just warning him. Think about it, if he gets injured and recuperates, he won't be in danger again, right? He will stay at home obediently, right?"

Matou Sakura rubbed the pages of the book in her hand nervously: "Is Senior okay now?"

"I'm sure it's all right."

Not to mention the thing in Shirou Emiya's body, just the fact that Izawa Sugi stayed there would make it impossible for him to watch Shirou Emiya die. Oberon curled his lips. He was a bad guy who would hold the hand of anyone who was thirsty for life, and would even help bad guys fulfill their ideals.

"I'm going to go play with Caster, who got into a fight with your sister yesterday."

Oberon thought of the arrows shot from the direction of Ryudo Temple and became excited. "By the way, Assassin has left the stage. Did you feel his power?"

Matou Sakura nodded silently: "Yes, but not much."

Assassin gave her a very strange feeling, a bit similar to the feeling of Rider and Archer. Although they were also in the Holy Grail ritual, the ritual did not restrict them strongly. Assassin's magic power dissipated too quickly, and only a part of it entered the Holy Grail fragments in her body.

The seal that Izawa Sugi took out had extremely strong confinement properties. Even if the magic power returned, Matou Sakura did not feel any shock to her consciousness or any feeling that her body could not bear it.

Instead, it feels like... well, the sour and refreshing feeling of drinking a glass of ice cola on a hot day.

"Really?"

Oberon said so.

Now only Berserker, Caster, and Saber are left.

Oberon thought casually, first find Caster to join forces to kill Berserker, then he would deal with Caster himself, and then use the connection with Izawa Sugi to forcibly change Izawa Sugi's status, backstab the unlucky Saber, and clear out the remaining Servants in one go, then the Holy Grail War would be over, right?

“That’s a shame.”

After Arthur experienced the feeling of his lord being backstabbed by Vortigern once, he must have been furious to death if he experienced the feeling of being backstabbed by King Uther again, right?

Oberon sneered. As a white dragon, of course he had to try his best to kill the red dragon!

Thinking of this, he said to Matou Sakura: "Try to keep an eye on your sister and don't let her get involved again. Anyway, your family's affairs have been resolved, right?"

Matou Sakura nodded after hearing this: "I understand."

After Oberon left, Sakura Matou walked to the window. She looked in the direction of the Tosaka family and waited silently for her sister, hoping that her sister would come back from the Tosaka family as soon as possible.

There is another one watching the Tosaka Residence from afar.

This person was none other than the Heroic Spirit Emiya who had helped Kiritsugu Emiya and repelled Izawa Sugi's attack.

As an Archer, Heroic Spirit Emiya has super long-range vision. He can see the battle in Emiya Mansion from the rooftop of Ryudo Temple and shoot directly from the direction of Ryudo Temple.

Caster Medea noticed that the Heroic Guard was consuming magic power and asked unhappily, "What are you doing? Who told you to do it without permission?"

The reason given by the Heroic Guard is that if Assassin lived longer, he might be able to see the abilities of other Servants more clearly.

The actual reason is very simple, that was Kiritsugu Emiya, his adoptive father when he was alive!

The reason why Shirou Emiya tried to become a partner of justice was because Kiritsugu Emiya, who had such an ideal, gave up. So Shirou Emiya as a child wanted to continue his father's wish and decided to go on as a partner of justice.

However, after becoming a Heroic Spirit, Emiya regretted it. He wanted to find an opportunity to talk to Emiya Kiritsugu, so he couldn't watch Emiya Kiritsugu die.

But who could have imagined that this Holy Grail War would be completely different from what he remembered.

Let’s not talk about the fact that King Arthur is actually a man, let’s just talk about how Merlin suddenly appeared?

The Heroic Guard is full of question marks.

The only thing that comforted the Heroic Spirit Emiya was that Tosaka Rin was probably not involved.

Otherwise, with the girl's pride and persistence, she would never let the Heroic Spirits go to fight while hiding at home and watching. She would only stand on the battlefield with the Servant.

Medea did not believe the reasons given by the Heroic Guard at first.

But soon, a pillar of light shone through the sky, and the radiance of the Sword of Promised Victory made Heroic Guard and Medea a little dazed.

Medea stopped scolding the Heroic Guard and instead instructed them to continue observing Saber from a distance.

Medea developed a strong interest in this powerful swordsman.

As for Ize Shan's King Uther status, Medea didn't pay much attention to it.

One is that the occupations of the servants cannot be determined, and the other is... Saber Arthur smashed the wall summoned by the enemy, so as long as we get Saber, we won't be afraid of new servants!

The Heroic Spirits looked seriously at Izawa Sugi who had transformed into King Uther, and recalled the Servant who had just transformed from a swarm of black insects into a human...

Wait, theoretically speaking, the only people connected to him in the Fifth Holy Grail War are Tosaka Rin and himself of this era.

Now that Shirou Emiya has summoned Saber King Arthur, only Rin Tosaka can summon him.

But he was still summoned by Caster Medea in an illegal summoning form, which means...

The expression on the face of the Heroic Guard was particularly ugly.

He came to the Fifth Holy Grail War, not to fight for the Holy Grail, but to protect humanity and save the world!

Who was the Servant who summoned Camelot? Why would they protect a Servant that was filled with such obvious disaster?

Just as the Heroic Guard was absentmindedly calculating the Servant that had appeared, Medea suddenly made a puzzled voice: "Who is it?"

The Heroic Spirit Guardian's eyes fixed, and a beautiful butterfly appeared in front of the gate of Ryudo Temple.

"It's me."

Oberon, wearing a pure white robe and looking like a fairy tale prince, stood on the steps in front of the mountain gate with a smile on his face.

"I want to talk to you about the alliance."

The Heroic Guard immediately stood up, two half-meter-long blades appeared between his hands, and he leaped forward and rushed directly towards Oberon.

"Wait." Medea began.

Heroic Guard clicked his tongue in his heart. He stopped at the gate and looked at Oberon warily.

Oberon was also amazed in his heart. Wow, another brand new Servant? Is the concentration of Servant in this Holy Grail War a bit high? Is the Holy Grail okay?

And what was this Heroic Spirit thinking? Damn, eliminating the disaster that could destroy the world...

Oberon is very upset, is it really that serious? Although releasing his original form will indeed destroy the world, but with Arthur's Sword of Victory and Assassin gone, how come a guardian with a mission appears again?

It's so annoying to feel targeted!

But... Oberon saw Medea standing behind the Heroic Guard in Ryudo Temple and smiled meaningfully.

Caster Medea doesn't know the little thoughts of the Heroes' Guard, haha, this is so interesting!

Medea stared at Oberon cautiously. "You just said, alliance?"

Oberon nodded and began to sell himself, something he was good at.

"Yes, Saber was my enemy in life. Although all the grudges are written off after death, I would still be happy to cause trouble to my past enemy if I have the chance."

Medea raised the corners of her lips and asked with interest: "Who are you? And who is Saber?"

Oberon said frankly, "Saber is the legendary knight King Arthur who unified Britain, and I am naturally the humble King Vortigern who was defeated by him and competed with him for the throne of Britain~"

Oberon? Who was that? He didn't know him! He was Vortigern!

As a magician from the Age of Gods, Medea knew little about some of the legends of later generations, but since the other party said it so frankly, it must be true. Anyway, she could ask the Lord of Protection Bathet for confirmation.

She said slowly: "It sounds interesting. I can form an alliance with you, provided that you become my Servant."

Medea took out a peculiarly shaped dagger and smiled meaningfully.

"Are you willing to sign a master-servant contract with me?"
