It is possible for a servant to remain materialized as a normal familiar after the Holy Grail War ends, but it greatly increases the cost without active support from the Grail.
However, even if a servant having a full supply of magic power disappears, if they lose their anchor to the world by the loss of their master, so they must quickly seek out another contract.
In truth, besides magic power, there are several ways for a servant to receive a magic power supply.
Like what the Black Faction did by using the homunculus to supply the magic power of their servants previously.
Besides Magic Power, a servant can also intake semen or blood for energy depending on their method of processing it.
Similar to what Raikou did to Haru, even if she could get a magic power supply from him, she still took energy from his semen.
"Huh?" 2x
Unlike Shakespeare, Haru didn't have an interest in this Caster of Red, but Atalanta was different. He would take the Holy Grail and wouldn't give it to the Magic Association or the church. Once the news that of the Holy Grail was on his hand, without doubt, he would become the target of two huge organizations.
However, Haru didn't care much since he could use his telepathic ability to manipulate the mind of those people easily.
If it was normal human, Haru might not do this, but his opponents were Magus.
Haru had an ability to manipulate someone else's mind, it was too wasteful to not use it, right?
Haru might be alright, but he was afraid those guys might target Fiore. He had to admit that this girl was too cute and he was afraid that something might happen to her once he had left this world.
Haru was sure that Semiramis didn't want to become Fiore's bodyguard, however, Atalanta was different.
"Atalatanta, if you become Fiore's bodyguard, then I will give you a fund to create a huge orphanage, and with that orphanage, even without the help of the Holy Grail, you can create an environment where a child with no parents can live well."
"........."
Atalanta looked at Haru with disbelief since she had never told him about her wish before, but how could this guy know about her wish?
"But you should be prepared, the children at this era are different from the children in your era and what can I do to help you might not be as perfect as you have imagined in your mind, even so, do you want to stay in this world? If so, then I will help you."
Haru stared at Atalanta with a serious expression.
If Haru had to choose between Atalanta and Semiramis, he would choose Atalanta without hesitation since Atalanta's personality was several times better than Semiramis, who was downright selfish and he was afraid that Semiramis might poison Fiore when there was a chance then used that chance to threaten him.
Atalanta then looked at Haru for a while then looked at Fiore. "I agree." She didn't want to return to the Throne of Hero and she also had a chance to save a child with Haru's help. Even though it might not be as perfect as she had imagined, she wasn't sure why she decided to believe in him.
"Good."
Haru nodded and smiled. "Then let's go back first." He stretched his hand and the Greater Holy Grail disappeared from everyone's eyes.
"..."
Caules wanted to say something but stopped the movement in his mouth. He knew that the moment the Greater Holy Grail was in Haru's hand then it was simply impossible to get it back.
Fiore wasn't sure why Haru decided to ask Atalanta to protect her, but then, she couldn't help but ask, "You really going to take the Holy Grail?"
"Yes." Haru nodded and asked, "Or do you have any wishes that you want to ask?"
Fiore shook her head and said, "No, but it is going to be dangerous if you really take the Greater Holy Grail since the Magic Association and the Church won't let you have the Greater Holy Grail." She was worried when she thought that Haru would be targeted and become a criminal in the eyes of two huge organizations, especially when the function of the Greater Holy Grail had been better and stronger after being modified by Shirou.
"Oh? Do you feel worried about me?" Haru asked with a smile.
"...."
"It's not a time to tell a joke?!" Fiore puffed her cheeks and felt a bit annoyed.
"Sorry, sorry, you don't need to worry about those two organizations."
Haru couldn't tell Fiore that he could manipulate the mind of someone by using his telepathic ability, but...
"If they dare to come then I will give them a nuclear bomb."
"..."
Everyone was stunned when they heard Haru's words.
"Nu... Nuclear bomb..?!" Caules opened his eyes wide, hearing those words.
Even if Magus might disdain technology, it didn't mean that they were clueless about it, especially when they knew about the prowess of nuclear bombs during WWII.
"Do you have a nuclear bomb?" Astolfo asked curiously.
"I have it."
Haru took out a nuclear bomb directly from his zipper pocket, showing it to everyone.
Now, the problem is, where has he gotten this nuclear bomb?
In truth, Haru had gotten this nuclear bomb from Tabane and it wasn't that surprising for her to own one or two nuclear bombs, considering she was the smartest person in her world and she didn't lack a channel to create one or two.
"..."
No one dared to move when they saw a nuclear bomb on Haru's hand, but when they saw him, they kept the nuclear bomb again, they sighed in relief.
Haru looked at Caules, Astolfo and Sieg, then asked, "Do you have any wishes that you want to ask?"
Sieg shook his head and said, "No, my wish is the liberation of my kind. My wish has been granted."
Caules pushed the frame of his glasses and said, "...No."
"Well, originally, I wanted to have a body so I could stay in this world, but since I have the master so then I don't need that kind of wish," Astolfo said.
Haru nodded and didn't say much since whether Sieg was going to use his magic power or semen to maintain Astolfo in this world, it wasn't his problem, and there was also one problem that he needed to solve.
"Wait! Wait! What about me!" Semiramis quickly said since her body had slowly disappeared.
Shakespeare didn't say anything since he knew that he had lost and he had a feeling that this young man might not care about him at all.
Atalanta was alright since she had an Independent Action Skill which made her able to stay in this world for a week or so, but Semiramis didn't have that skill and she would disappear soon.
"Sorry, but I don't intend to keep you," Haru said.
"What?!"
Semiramis was dumbfounded.
Haru had made this decision since he felt that Semiramis was too dangerous. Even though his charm was high, it was impossible for someone to fall in love with him so fast, and it was also impossible for someone like Semiramis to share her love with someone.
If Semiramis loved someone, without doubt, she wanted to monopolize that person by herself, unless Haru was given time.
However, Semiramis was too dangerous.
Semiramis might be beautiful, but Haru had seen a lot of beautiful women and this woman had tried to kill him after all.
"Sorry."
Hearing "sorry" from Haru's mouth, Semiramis wanted to say something, but suddenly her eyes dilapidated and she turned into a particle of light before disappeared.
"....."
"Let's go. It's dangerous here."
Haru grabbed everyone, then they quickly teleported back, leaving the Hanging Garden of Babylon that was destroyed in the sky.
