Zalmora Nebiros.
This person is the head of the Nebiros family, an Extra-Order demon family.
The so-called Extra-Order families are demon nobility that exclude the royal families and those not among the 72 Pillar lineages.
Among them, six Extra-Order demon families served the original Lucifer Demon King.
Agalia Rept, Satanakia, Furote, Sagtanas, Nebiros, Lucifuge.
They were also members of the Old Maou Faction before the reforms, with Grayfia Lucifuge being one of its leading figures.
After the Old Maou Faction's failure, Zalmora Nebiros disappeared from the scene, retreating to the borderlands of the underworld to research weapons comparable to Sacred Gears, the 'Claw of Evil'.
Of course, more of his research focused on the peculiar phenomenon of 'Transcendents'.
The research institute secretly run by the Nebiros Branch Family to artificially create Transcendent Devils was backed by Zalmora from behind the scenes.
A few months ago, Rias's artificial familiars, butterflies condensed from the Power of Destruction, discovered the Nebiros Branch Family's research institute and confirmed information about the Tōjō sisters and their parents.
During this time, Rias had been monitoring the institute.
Until recently, when the Tōjō sisters' father's experiment failed, causing a massive disturbance within the institute.
"It's time to collect the experimental data on the artificial Transcendent."
Rias murmured, unfurling her wings behind her, then flew out through the library window.
"Heading out, Little Rias?"
In the courtyard, Venelana Gremory, Rias's mother, called out upon seeing Rias in the air.
"Yes, to find peerage members."
Rias nodded.
"Already recruiting peerage members... As expected of my Rias, truly impressive." Venelana smiled and said, "Gasper and Valerie are good children, but they're still too young."
"Speaking of which, should I apply for a set of Devil Chess Piece for you?"
Venelana seemed to have just thought of this and asked.
Except for the King Piece, all pieces are issued by Demon King Ajuka.
The essential requirement to apply for Devil Chess Piece is to become a High-Class Devil.
This is the most basic qualification.
"Not needed."
Rias said, "Brother Sirzechs got me the construction method for Devil Chess Piece. I've already constructed my own unique devil piece system."
"I see."
Though somewhat surprised, Venelana didn't show it, instead smiling gently and saying, "Come back soon~"
"I'll be back in time for dinner."
Rias said, "By the way, Mother, do you like cats?"
"Cats..." Venelana thought for a moment and said, "I like all cute things."
"Alright then."
Nodding, Rias flew away.
"That child's wings are so beautiful."
Venelana sighed, thinking, "Should I have Little Rias make one for me too?"
"No, forget it. They're so beautiful because those two children suit red so well."
"But cats... probably another cute child, I suppose."
Many demons have a special affection for cats.
After all, when one thinks of demons, black naturally comes to mind, and demonic affairs are often associated with black cats.
When Sirzechs was summoned by Okita Souji, he was also summoned in the form of a black cat.
"Already arrived."
Rias came to a stop.
Her wings were constructed from Destruction energy, but the fixed Magic Formula within them was the Heavenly Transfer of the Flugel.
The mode of movement wasn't flying through demonic talent, but directly moving through space.
For the Flugel, space is akin to water; they can travel through it simply by opening a hole, as effortless as breathing.
Traveling via spatial movement, she reached her destination in the blink of an eye.
"Then, let's begin."
Rias constructed a barrier and then walked into the research institute.
Rias already knew the location of the data storage. She quickly organized the experimental data on the artificial Transcendent.
"To cover our tracks, let's start with a Magic Bullet."
Rias deployed a Magic Formula within the institute. After she left, it violently erupted with raging Power of Destruction.
Boom!!
A tremendous roar sounded as everything within the research institute was utterly destroyed.
After destroying the institute, the residual Power of Destruction gathered together, forming red butterflies that slowly flew away from the site.
The Magic Formula Rias left behind was a dual-layered technique. One layer was for destruction, the other for gathering the residual magic power, achieving a truly traceless disposal of the evidence.
"The Nebiros Branch Family has no value left either. Let's see if Zalmora sends anyone to observe the situation here."
The Claw of Evil possesses a body, its own consciousness, and is a living Demon King-style 'Sacred Gear'—
They not only possess terrifyingly powerful strength themselves but also have other uses. That is, like a 'Sacred Gear,' they can transform into weapon forms and be equipped and used by a wearer.
Therefore, the Four Great Demon Kings refer to their 'Claw of Evil' as 'Demon King Armaments.'
Rias is somewhat interested in the Claw of Evil, but only to a degree.
Sheer, immense power is meaningless because Rias can create power even greater than that.
Transforming oneself into a weapon form isn't particularly difficult either; a certain degree of energy control is sufficient.
And from the surface, it's clear that the power of the Claw of Evil must be extremely violent and dangerous.
Rias has no need for such unstable power.
Weapons created purely for the sake of power cannot go far and cannot keep up with Rias's progress.
But they can't simply be left unchecked either.
Trash should be thrown into the trash bin.
After arriving at the Nebiros Branch Family estate, Rias entered a certain room.
Two cats were lying on the bed, enjoying the comfort of an afternoon nap, unaware that their 'father' and mother had already died in the experiment.
"Good afternoon."
Rias chuckled softly and, without disturbing them, used spatial teleportation to send the two cats to her own room.
A small Energy Sphere was held in Rias's palm as she played with it, exploring the entire Naberius family estate.
"No innocents here."
As the words fell, the Energy Sphere dropped to the ground.
Boom!!
There was no physical sound, yet it felt like a tremor to the heart.
A massive energy maintained as a sphere suddenly expanded, enveloping the entire Naberius family estate within it.
Countless streams of Destruction energy flowed, confined strictly within the spherical interior without spreading outward.
Over ten seconds later, the expanded red sphere collapsed inward, quickly condensing back into a smooth, round bead.
Picking up the bead to play with in her hand again, Rias revealed a smile of keen interest.
Fusion Equation, Second Stage—
Perfectly controlled fusion!
