Standing blankly at the doorway, Kiritsugu Emiya suddenly noticed the conference room door opening. Normally cold and rigid, Acht appeared almost smug at this moment, respectfully escorting a woman—a Magician—and her sister out of the room.
Following closely behind Acht was Kiritsugu's wife, Irisviel von Einzbern.
Noticing a trace of worry on Irisviel's face, Kiritsugu quickly stepped forward to inquire further.
"Iri, what happened?"
Kiritsugu asked, his voice laced with concern.
"Kiritsugu, the Einzbern family..."
Irisviel hesitated, seemingly unsure how to explain.
"...The Einzbern family might soon belong to the Aozaki sisters."
"?!"
Kiritsugu was instantly alarmed. Grasping his wife's hand, he pressed on, "What do you mean? Did those two women force Acht into this?"
"It's not like that," Irisviel shook her head.
"Miss Aozaki Touko, she's—"
"Irisviel! Keep up!"
Acht's stern voice interrupted before she could finish. Irisviel glanced at her husband, then hurried to follow Acht.
Kiritsugu stood frozen, watching his wife walk further and further away, heading toward a place he could never reach. A surge of complex emotions welled up in his heart.
Touko and Aoko Aozaki, along with Acht and Irisviel, arrived at a massive underground alchemical laboratory belonging to the Einzbern family.
This expansive space seemed to be the true heart of the Einzbern legacy. It was here that disciples of the Third Magic User had created Justeaze, and where all the Einzbern homunculi, including Irisviel and Acht, were born.
The Aozaki sisters wandered about, curiously inspecting the alchemical equipment scattered across the workshop.
"Miss Aozaki Touko, is there anything specific you need?"
Acht inquired, rubbing his hands together, his usual aloof demeanor completely absent.
"The facilities here are quite comprehensive," Touko nodded with an air of approval, crossing her arms.
"However, some materials will need to be procured. I'll also need to modify these alchemical devices. Additionally, I'll require Miss Irisviel's cooperation to use her soul as a template for the replication process. Is that acceptable?"
"Just provide me with a list, and we will prepare everything immediately," Acht replied. He then turned to Irisviel.
"Irisviel, from now on, you are to follow Miss Aozaki Touko's orders. Understood?"
"Yes, father," Irisviel obediently replied.
She cast a mix of curiosity and trepidation toward Touko, who was much shorter than her. Such a young girl, yet already a Grand Magus and someone close to mastering the Third Magic?
She looked... rather cute. Perhaps she could become friends with Illya…
Noticing Irisviel's peculiar gaze, Touko immediately shot her a sharp glare.
"Irisviel, was it?"
Touko spoke in a slightly harsh tone.
"Come here and lie down. I need to inspect the Lesser Grail's structure."
Obediently, Irisviel lay on a surgical table in the center of the room, allowing Touko to examine her.
"Hmm... interesting," Touko murmured as she worked.
"A clever design... She's modeled after the body of the Third Magic User, isn't she?"
"Indeed," Acht nodded.
"Strictly speaking, Justeaze was the closest replica of the Third Magic User. Irisviel is the best approximation we could create with our current capabilities."
Sitting off to the side, Aoko found a chair and watched Touko and Acht's exchange with amusement. It was evident that Touko was deeply intrigued by the Einzbern's technology and its connection to the Third Magic.
"I'll need three days to create a replica of Irisviel, including her soul, mind, and body," Touko declared.
"Of course, when I start depends on how quickly you gather the materials."
"Understood!"
Acht affirmed.
"Once you demonstrate your capabilities, we will discuss the specifics of our collaboration for the Holy Grail War."
"...If our millennia-long wish can be fulfilled, the entire Einzbern legacy will be yours, Miss Aozaki Touko."
...
Three days passed swiftly.
During this time, Aoko and Touko enjoyed the opulent lifestyle of the decadent aristocracy. A host of white-haired, red-eyed homunculus maids tended to their every need, rekindling memories in Aoko of her past life as a transmigrator.
While Touko worked in the alchemical workshop during the day, Aoko roamed the massive castle at her leisure. At night, they shared a room to guard against any underhanded attempts by Kiritsugu.
During one of her explorations, Aoko encountered Illya, who was happily wandering the halls. The adorable girl was curious about the young, beautiful sister, but before she could approach, Kiritsugu dashed in with a wary expression and whisked her away.
Just you wait, Kiritsugu Emiya. Your reckoning will come.
Smiling outwardly, Aoko's expression remained calm, but her mind was already crafting a series of elaborate plans to utterly humiliate this middle-aged edge lord during the Holy Grail War in two years.
Hehehe.
Aside from Illya's charm, Aoko and Touko also indulged in the Einzbern's luxurious baths, receiving massages and scrubs from two homunculus maids who bore a striking resemblance to Sella and Leysritt.
Aoko suspected their identities but couldn't confirm them due to the homunculi's similar appearances and the headscarves obscuring their hair. She had to rely on the size of their assets for identification.
Their massage skills, however, were exceptional. It seemed the magi who designed them had embedded extensive service knowledge into their programming.
Once Touko gains control of the Einzbern, I'll bring two homunculus maids home to enjoy a life of decadent luxury. The pair serving them now seemed like good candidates...Hohohoho (laughing queen.gif).
