On the way to the Emiya residence, Kazuya asked, "By the way, you seem to have adopted Emiya Shirou, right? What was his original name?"
"Murasa Shirou. That was his original name," Emiya Kiritsugu said as he drove. "But now, he's called Emiya Mumei."
"...Hmm, I see."
Hearing the family name, a certain heroic spirit appeared in Kazuya's mind.
"What's the matter?" Emiya Kiritsugu asked, looking at Kazuya through the rearview mirror.
"It's nothing."
Emiya Kiritsugu furrowed his brow slightly, sensing that something was off, but decided not to press further.
"We're here."
Emiya Kiritsugu slowly stopped the car and said, "This is it."
At the door, someone had already come out upon hearing the sound. It was none other than Maiya Hisau.
"You're back, Kiritsugu."
"Yes," Emiya Kiritsugu nodded, opened the car door, and got out, saying, "You already know each other, so I won't introduce you again."
On the other side, Kazuya also got out of the car. "It's been a while, Hisau-san."
"Welcome, Kurokawa-san," Maiya Hisau said with a bow. "Well then, I'll take care of things here. Kiritsugu... Your wife is waiting for you."
"Yes," Emiya Kiritsugu nodded. "Please."
Kazuya also nodded, and the two of them went inside. On the other side, Maiya Hisau drove the car into the nearby garage.
"Welcome back, Kiritsugu. Uh... who's this?" Irisviel, wearing an apron, asked in confusion.
"This is Kurokawa Kazuya, the person I brought to teach you all about Ripple Energy," Emiya Kiritsugu said, turning to Kazuya. "This is my wife, Irisviel."
"Hello, Emiya-san," Kazuya also bowed and greeted.
"Uh... well... hello," Irisviel hesitated for a moment, then her fair face blushed slightlydue to the clothes she was wearing.
"Tonight, it's Iris cooking," Emiya Kiritsugu said, looking at Irisviel's attire.
"Yes, I've been learning to cook recently," Irisviel said with a smile. "After all, we don't have servants now, and I can't always let Maiya-san do it. I've learned how to cook properly... How about trying it? Kiritsugu..."
"Of course, I'll give it a try," Emiya Kiritsugu nodded.
Irisviel smiled, "Excellent. I'm actually quite confident about this round of cooking. Kurokawa-san, what about you? Let's eat together."
"...No, it's alright. I've already had dinner, and I'm a bit full now. I probably won't be able to eat," Kazuya replied with a smile.
"Is that so? That's a shame."
At the back, after parking the car in the garage, Maiya Hisau came in and wanted to say something but swallowed it back and didn't say it.
However, Kazuya caught a glimpse of it.
In reality, he didn't know how Irisviel's cooking was, and he hadn't had dinner...
But judging from the cooking in Einzbern Consultation Room and the dishes cooked by Illyasviel in Fate/kaleid liner Prisma Illya, he could tell.
That was definitely not meant for human consumption!
And looking at Maiya Hisau's face from the corner of his eye, it didn't look like something decent.
Afterwards, everyone introduced themselves to each other, and Kazuya also saw the boy now called "Emiya Mumei."
Though he said that, he was a bit different from the Emiya Shirou he knew, with the most noticeable difference being the whiteness of his hair at the front... It could be said that way. A significant portion of his hair at the front was white.
One could only say that parallel worlds were truly marvelous...
The Shirou in this world seemed a bit different from those in other worlds.
"Alright, Kiritsugu, Illyasviel, and Mumei, let's give it a try."
"Okay, I'll give it a try," Emiya Kiritsugu also felt a bit uneasy.
Illyasviel and Emiya Mumei looked at him with strange expressions. Irisviel was full of expectation, and Maiya Hisau had turned away.
It seems... it's not bad...
"Umm..."
"How is it?" Irisviel asked Emiya Kiritsugu as he tasted the dish.
"Good, not bad..."
At this moment, Kazuya only had one thought... this scene could probably be made into a manga.
Too bad he didn't have a pen.
...
"Can I learn too?" Emiya Mumei asked, puzzled, looking at Kazuya.
"Of course, it doesn't matter if there are a few more of you," Kazuya said to Emiya Kiritsugu and Emiya Mumei. "Having a few more people won't make a difference."
And... The Ripple user, Emiya, sounds pretty cool.
"What about Granma? Can Granma learn?" Emiya Mumei asked.
"No, forget it," Kazuya shook his head. "An elderly person's body is more fragile. If something goes wrong during the training and they faint... that would be bad. But if you don't mind, then it's okay."
Older people naturally had less life energy, even if they learned, there wouldn't be much progress, and they might not even be able to learn.
Moreover, if something happened during the learning process due to not adapting to this kind of breathing, it would be bad. Although the Ripple had a healing effect, it could only provide a bit of healing for the living, not the dead.
It wouldn't be surprising for someone of this age to have various issues.
"Hmph! Watch, Illyasviel will definitely be the first to learn," Illyasviel said, hands on her hips. "Let me show you what a genius is."
"Alright, let me see your talent, Illyasviel, the first one?" Kazuya smiled and said.
"No—Dad will be the first, alright? Is that okay?"
"Of course, my princess," Emiya Kiritsugu smiled and said.
"Well then, are you ready?" Kazuya, extending a finger and poking, "First, let's get used to it... Oh, by the way, in that JOJO theme park of mine, I really built a Hell Climb Pillar. If you're interested in improving your Ripple, just let me know."
Cough, cough—
The five of them started coughing, and after a while, their breathing gradually returned to normal. While this didn't make them learn the Ripple immediately, it was good to get used to it, making the learning process easier later on.
So, during this period, Emiya Kiritsugu contacted the people he was familiar with to prepare the "Mystic Eye Killers."
He taught everyone in the Emiya household, except for the old lady, about the Ripple.
