Even though this castle was much smaller than the one in Germany, it still lived up to the name of a castle.
Luxurious, extravagant, large!
The area was nearly 10,000 square meters!
It had gardens, courtyards, a swimming pool, underground workshops, and so on.
Each room was dozens of square meters in size, with the master bedroom reaching a hundred square meters.
Apart from modern facilities, it basically had everything.
Well, there were also Einzbern maids living here, so everything was kept clean and tidy.
In addition, Sella and Leysritt, who had accompanied Illya as she grew up, were also here.
They were relatively well-developed homunculi, second only to Irisviel's level.
Both in terms of Magic Circuits and personality.
Among them, the long-haired Sella was capable of all household tasks and was responsible for Illya's education. In the Prisma Illya timeline, she was also very strict.
As for the short-haired Leysritt, she was better at combat, average at housework. In the Prisma Illya timeline, she was even a shut-in who only ate snacks and did no chores.
Perhaps because of this…
Leysritt's chest seemed bigger than the others', while Sella was about average.
Really, you might not be able to tell seeing her in a maid uniform.
But after Kaito curiously investigated...
Damn, it's slightly bigger than Irisviel!
It's ranked first in Fate and seventh in the Nasuverse!! (Excluding FGO)
At the time, Kaito found it absolutely unbelievable!!
Until he saw some notebooks, and he was speechless.
"Kaito, let's go soak in the hot spring together! There's an open-air artificial hot spring! And it looks very beautiful!"
After everyone familiarized themselves with the Einzbern Castle, had lunch, and divided up the rooms, in the master bedroom, Irisviel happily invited Kaito to soak in the hot spring after tidying her clothes.
"Okay."
Kaito didn't refuse.
So, led by the two head maids, Sella and Leysritt, they arrived at the location of the artificial hot spring.
It was indeed very beautiful and luxurious.
Medieval European style, various carvings on stone pillars, and some artistic reliefs of beautiful women, etc.
Kaito, with Irisviel's personal assistance, undressed, washed up, and then entered the hot spring. Irisviel, with Sella's help, also got everything ready, then sat down beside Kaito.
At this moment, Irisviel was experiencing the feeling of being in love, or the feeling of being a wife.
Although the pace was a bit fast and very direct, this was Irisviel's personality.
She wasn't as complicated in her thinking as real adults.
"Mm, so comfortable. And the climate here in Fuyuki City is quite warm even in winter."
"Compared to where we lived before, it is indeed much warmer here."
Kaito smiled, put his arm around her shoulder, gently pulled her close, and looked up at the sky.
"Kaito, when the Holy Grail War starts in a year, will you participate with me?"
"Maybe, it depends. It's possible."
He couldn't say he could defeat all seven now, but he could certainly fight.
Besides, he didn't know how strong he would be in a year.
Maybe he would skyrocket directly, able to face Goetia or Tiamat head-on.
If he was unlucky, he might stagnate.
"Hehe, with you here, I'll feel much more at ease. As for the Third Magic, I'll give it to you then."
"The Third Magic, huh..."
Speaking of this, Kaito thought for a moment.
Not to mention the Holy Grail issue, just the Third Magic itself seemed to have some benefits for him.
But thinking of it as a true perpetual motion machine was impossible.
Magical energy might be supplied infinitely, but the speed definitely wouldn't be instant replenishment after consuming a large amount.
The greatest use of the Third Magic was the materialization of the soul.
Using cultivation novels as an example, it's roughly like cultivating a primordial spirit, being able to fight with it, and being able to recreate the body if it's destroyed, to that extent.
Even if it would be much weaker, as long as the soul doesn't die, it's fine.
"We'll talk about it then."
He hadn't yet had a chance to explain that the current Holy Grail was already corrupted, but maybe it wasn't corrupted yet.
Well, whatever.
At worst, he could just have King Arthur, Artoria Pendragon, use her Noble Phantasm to smash it.
Regarding smashing the Holy Grail, Artoria is the most professional.
"Speaking of which, which Servant do you plan to summon?"
"Hehe, it's King Arthur! High probability! Because the Einzbern Family treasures the scabbard that King Arthur lost back then!"
"I see. If I told you King Arthur was a woman, what would you think?"
"Huh?"
Irisviel was stunned for a moment, very curious why Kaito would ask that. But thinking of King Arthur being a woman made her feel a bit strange.
Whether from books or movies, King Arthur was either a bearded, rough-looking strongman, or a handsome and dashing knight.
A woman?
How could she imagine that!
If King Arthur were a woman, what would the people of Britain think?
"That's strange. If it really were a woman, she should be very valiant and heroic, right? By the way, why do you ask? Did you see it with your future-predicting ability?"
"Hahaha, I was just asking casually."
Kaito laughed it off and didn't continue the topic.
Maybe he could even summon the Northern Hemisphere!
That is, the grown-up version of Artoria, the Lion King Artoria, or Rhongomyniad.
As a fan of the King, Kaito wanted both.
To be greedy, the Caster version (the village girl) of Artoria wouldn't be bad either.
By the way...
Since he had already destroyed the Matou Family, maybe he could become a Master himself?
Unfortunately!
It depended on whether the Greater Grail would acknowledge him, or how Alaya and Gaia viewed him, an outsider.
...
"Huh? What's this..."
Suddenly, Kaito's consciousness sank into darkness. When he came to, he found himself not in the hot spring, but in space?
And his current form... also seemed to be a soul?
"Greetings, Outsider."
A small, blurry figure appeared beside Kaito, but at the same time, another equally small figure gradually emerged behind her.
Seeing this, Kaito couldn't help but laugh.
He had just been thinking about Gaia and Alaya, and now they had summoned him!
While finding it interesting, he also felt a slight fear inside.
This fear was the fear of his own insufficient strength.
He had been brought here so easily; if they wanted to harm him, wouldn't he be unable to escape?
