Many Sacred Gears, in fact, are not original prototypes but imitations created by the God of the Bible, who mimicked their powers.
Just like the Holy Grail from the Bible, the true Holy Grail has long since shattered, leaving only the trinity 'Sephiroth Graal'.
Or take Gasper's 'Evil Eye of Stasis' as another example; it is essentially an imitation created by replicating Balor's ability. As a result, the Sacred Gear was drawn to Balor's reincarnation and converged upon Gasper.
The Spear of Twilight is also likely not the original prototype. The true original should be called the 'Spear of Longinus', which has probably been destroyed by now.
The Sephiroth Graal is a replica, but perhaps it possesses power not inferior to the genuine article.
The Magical Device: Holy Grail is a replica of the Sephiroth Graal, possessing equivalent functions.
This perfectly embodies the domestic talent for imitation. Even the God of the Bible would probably be stunned to see it.
After all, He imitated others to create many Sacred Gears and likely never imagined that He Himself would also be imitated.
"The mastery over life..."
Rias murmured.
The Holy Grail possesses many functions: eliminating racial defects, resurrection, healing, energy conversion.
At its core, it is mastery over life.
Even if the soul is mostly destroyed, as long as a tiny fragment of the soul remains, the Holy Grail can resurrect it.
Only if the soul is annihilated to the point where not even a trace remains would the Holy Grail be limited to 'replicating' it, which couldn't truly be called resurrection.
Thinking about it now, that God truly lives up to the title 'Omnipotent and Omniscient'.
Although not truly omnipotent and omniscient, He was still all-powerful.
"Eliminating racial defects, followed by physical evolution."
Rias murmured, allowing the power of the Holy Grail to flow into her body.
She could feel the activity of her body's cells, gradually strengthening her physique.
"Because there's no specific data, it's difficult to achieve?"
Rias experimented with the Holy Grail's performance, then took out another magical device.
The Analysis Cube —
This was formed by Rias integrating the knowledge of the Analysis Formula into a magical device. It could be deployed quickly and saved her effort.
Moreover, the performance of the Analysis Formula was even higher than Rias's own!
Not only that, the Analysis Formula also had the function of recording data.
Ultimately, Rias was still flesh and blood. No matter what she did, it required effort. How could she compare to a machine?
And the greatest distinction between humans, intelligent life, and beasts is the ability to use tools.
And Rias was an outstanding example among them; she could create tools.
Following Rias's actions, the Analysis Cube transmitted Sirzechs's data into the Holy Grail within her body, and the evolution of Rias's body also began to intensify.
Although she still maintained the appearance of a four-year-old on the surface, her internal state had undergone a tremendous transformation.
If Sirzechs was the Complete Body, then Rias was the Mature Stage.
From Infant Stage to Growth Stage, from Growth Stage to Mature Stage, from Mature Stage to Complete Body.
This step marks the boundary between ordinary demons and Transcendents.
"Even I can't help but be shocked by my own speed of evolution."
Rias sighed.
It was too fast. If she could obtain the Hōgyoku, perhaps she could complete her evolution even faster.
The Fusion Equation, the Holy Grail, the Hōgyoku.
These were all key items that accelerated her growth in different fields.
"That's about enough for now."
Rias stored the Analysis Cube and the Holy Grail inside her body, allowing them to operate automatically.
As for Rias herself, she went to the living room.
The two cats had already woken up and were being soothed by Venelana.
"They really are two adorable kittens."
Venelana said with a smile.
"Their parents died accidentally during an experiment. I brought them back when I went to the Nebiros Branch Family's research institute to retrieve some data."
Rias said, then looked at the little girl form of Kuroka and said: "Incidentally, the Nebiros Branch Family has been destroyed by me. I won't use you as a test subject either. You can live here peacefully."
"!!"
Hearing this, Kuroka's spirits lifted, and her two cat ears couldn't help but stand up straight.
Toujou Kuroka was a bit older than Rias. Having lived in a place like the Naberius household, which lacked warmth, her mind had matured early.
Although she felt uneasy about suddenly coming to the Gremory Family, fortunately, she had met a gentle person: Venelana.
She was more like a mother than Fujimai.
"Are you going to be Kuroka's master in the future, nya?"
Toujou Kuroka asked with a cute expression.
This child was a bit too shrewd, wasn't she?
"Hmm... Master is fine, or you can call me sister."
Rias stood on her tiptoes and patted Toujou Kuroka's head.
"Mmm, Master, nya."
Toujou Kuroka blinked and still chose the title 'Master'.
After all, Rias clearly looked younger than Toujou Kuroka. Although her demeanor was mature, 'Master' still seemed more appropriate.
"I am Toujou Kuroka, nya. The white one is my little sister, Shirone, nya."
Toujou Kuroka introduced.
"I am Rias Gremory."
Rias responded, saying: "From now on, this will be your home."
Stroking Toujou Kuroka's head and petting her ears, Rias felt that bringing these two cats back was the best decision she had ever made in her life.
When Rias let go, Toujou Kuroka gave a shy smile, looking utterly adorable~
After arranging rooms for the Tachibana sisters, Rias sat on a chair, swinging her feet.
"What kind of experiment was Naberius conducting?"
Venelana asked.
"Artificial Transcendents."
Rias did not conceal it.
She figured Venelana asked out of concern, perhaps thinking Rias had gone too far in wiping out the Naberius family.
Although Rias's intelligence was so high that they didn't impose many restrictions on her, conversely, innate high intelligence also made it easier to go astray. Venelana, Zeoticus, Sirzechs, and Grayfia were all worried about this.
After all, the fact that their Gremory family valued emotions was considered peculiar among demons, but they themselves took pride in it.
"Phew, I see."
Venelana seemed to sigh in relief, patting her chest.
"Your worries are unnecessary, Mother."
Rias smiled and said: "On the contrary, there are other areas you should be more concerned about."
"Other areas?"
Venelana blinked her eyes.
Rias smiled without speaking, making Venelana feel as if her heart was being tickled.
"Leaving your sentence half-finished, you've learned to be mischievous too, child."
Venelana tapped Rias's forehead with a smile and held Rias in her arms.
A moment later, she placed Rias's head on her lap, gently stroking Rias's head.
"We rarely have such close contact like this, Little Rias."
Venelana sighed: "It's completely different from Little Sirzechs. That child loved to act spoiled when he was little."
"Personality is one-tenth innate and nine-tenths nurtured. Brother Sirzechs is so gentle; it's clearly influenced by you, Mother."
"As for me, I'm a reincarnator with memories, possessing a complete worldview from the very beginning."
"For me, the infancy period has long since passed."
Rias said softly.
"It must have been hard."
Venelana said gently.
"Not hard at all." Rias smiled: "I live according to my own will. How could that be described as hard?"
"That's wonderful then." Venelana gently stroked Rias's head and said: "Although I sometimes feel lonely, Mother also sometimes thinks how wonderful it is that Little Rias is my daughter."
