Normal POV
The muffled sounds of person can be heard as Jack Allen takes a needle and withdraws a small bit of blood from his current victim.
Benjiman Ricardo was a necromancer and magus from a minor noble family.
Like most magi though Benjiman was someone that furthered his craft by experimenting on other humans.
An indulgence excused under the veil of "research" and "progress," in the name of the root.
Jack stared at him with detached calm the same amused smile playing across his lips.
His gloved hands moved, placing a drop of the blood onto an empty blood slide that had Benjiman's full name labeled on a small corner.
"Benjiman Ricardo," he said softly like a teacher reading a name off a roster "necromancer, experimenter, and a human butcher," his smile sharpened though his gray eyes remained flat "it really is kind of funny isn't it? For all that pride you have, you didn't even notice when someone entered your own workshop."
He set the slide neatly in his trophy case tucking it into the row of others he had collected over the years.
His private gallery.
A ritual.
Benjiman squirmed the gag muffling his protests into pitiful animalistic noises as he desperately tries to shake himself off the table he was strapped to.
Jack crouched to meet his eyes tilting his head in that same too-friendly way a neighbor might ask how your day was going "shh don't ruin this moment with noise. You had your turn months of it, maybe even years listening to people scream in your workshop. Did you savor it? Did you write it down in your little journals? …Or did you just call it 'research' and sleep like a baby?"
His tone never shifted from conversational pleasant even but his hands were already grasping for one of his favorite daggers.
A mystic code that had the properties of a hydra.
Jack had actually looted the thing from one of his previous victims a few years back. Some arrogant magi who believed himself untouchable because of his family name and the "gifts" his Crest gave him.
A bit similar to this moron that he was dealing with.
With a subtle bit of focus his gray eyes gained a bright blue hue to them signifying the activation of his mystic eyes of death perception.
Normally a pair of mystic eye killers would have to be used in order to nullify it's effect but for Jack it was all a matter of shifting his focal point to get his eyes back to normal.
With a swish Jack cut the line of death on both of Benjimans arms and legs.
The effect was instantaneous.
The necromancer's body seized violently as if the strings of a puppet had just been slashed. His muffled scream cracked into something primal and broken as the limbs turned dead weight against the leather straps, bones and nerves alike ceasing in an instant.
Jack tilted his head watching the spasm play out with the same idle curiosity one might reserve for watching a fly drown in a cup of wine.
"Fascinating, isn't it?" he murmured twirling the hydra-bladed dagger between his fingers "it doesn't matter how much some can reinforce themselves or how many bounded fields they put up around themselves. In the end the human body is fragile, everything has an end and me-" he gestured towards himself with the blade which gave off a glint from his glowing eyes "-I just happen to see where those ends are hiding."
Jack crouched closer, his smile widening but his tone remained soft almost sympathetic.
"You feel it, don't you? That cold rush down your arms like your blood suddenly forgot how to flow. That emptiness where your legs should be I've seen it so many times people thinking they're dying slowly when in truth…" he leaned in until his lips nearly brushed the necromancer's ear "you were dead the second I cut your lines of death."
Benjiman thrashed weakly the leather straps biting into skin that could no longer resist.
A low animal moan clawed up his throat, pitiful and broken.
Jack leaned back and sighed through his nose setting the dagger flat against his palm as though weighing it.
His eyes dimmed back to gray leaving behind only that too-bright smile.
"You know what the best part about this is, Benjiman?" His voice dropped to a near whisper, conversational, intimate "you did this exact same thing to dozens of other people. You sat them where you sit now, watched them writhe, catalogued every scream, every nerve's reaction to your little experiments. And now that it's your turn you finally understand what your notes could never capture...the helplessness, the inevitability that your about to die."
The hydra dagger's edge caught the lamplight as Jack pressed it lightly against the necromancer's throat not enough to cut, just enough to let the cold kiss of steel sink in.
Benjiman's brown eyes bulged and his gag muffled another strangled howl.
Jack's expression softened suddenly almost tender as he patted the man's sweat-soaked cheek with his gloved hand.
"Don't worry I'm not going to kill you yet. No, no… not until I've heard enough of those sounds you've given to others. A scream for scream if you would," Jack said as he cut more lines of death along Benjiman's body.
His screams of agony were like joy to Jack's ears and he allowed himself to embrace this bliss for a good hour until he decided to finally end his ritual.
"Now you have my permission to die," he uttered piercing the heart of the scumbag with his hydra dagger.
The necromancer's body convulsed violently a wet gargle tearing through the gag as blackened veins spread outward from the wound like wildfire.
The hydra venom oozed from the blade's edge into his bloodstream each droplet carrying a hundred deaths, that turned his flesh into rotting decay.
Benjiman's eyes bulged wider than before brown irises swimming in terror as his screams strangled themselves into a bubbling choke. The venom didn't kill swiftly it only multiplied the agony, replicating endlessly.
His nerves lit up like firecrackers.
First came the feeling of drowning in acid, then the sensation of his organs swelling against his ribcage, each beat of his dying heart pumping more poison into his system. His legs jerked limply dead weight now as they had no life, but still spasmed in grotesque imitation of life.
Jack tilted his head again watching with that gentle curiosity as though studying a specimen under glass.
"Ahhh," he breathed almost reverent "this part never ceases to amaze me…the way it spreads. A thousand tiny deaths at once it's like your body can't even decide which one to surrender to first."
Benjiman's throat bulged with another animalistic howl muffled into nothing but spit and blood against the gag. His chest heaved desperately fighting to draw in air even as his lungs began to blister under the venom's assault.
The necromancer's eyes finally rolled white.
His body thrashed once more for a few moments before the convulsions slowed.
His skin split in places where the poison surged too violently blood bubbling black.
Then his heartbeat fell into silence.
Only then did Jack withdraw the dagger watching the corpse relax in its bindings like a puppet with its strings cut.
He let out a sigh of content as his dark passenger was satisfied for the time being.
Carefully he used some of Benjamen's spilled blood and drew both the Kenaz, Sowlio runes setting the body on fire before he snapped his fingers allowing the body to then be sucked up by his imaginary number space.
Afte Jack carefully cleaned up the workshop tossing any evidence away in his space before leaving the former workshop of Benjamen Ricardo.
No one would know that his life and disappearance was caused by the one most had called...the angel of death.
Jack's phone suddenly rang, and he quickly reached into his pocket to answer, "hey big brother what's up?" he greeted the person on the other end like he hadn't just spent a better part of his day torturing and killing someone.
-end of prologue-
From here we move on to the case files of lord El-Melloi after that we can jump into the Fate Route and have him replace Atrum.
For his looks were going to go with Toji Fushiguro only less bulky looking and more of a thin athletic build.
Signature clothes will be a loose white shirt, black pants, and dark brown shoes.
Decided Affinity is obviously 'Imaginary Numbers.'
Still debating on what his origin would be.
Anyways pick a pairing:
MC x Gray.
MC x Rin.
MC x Sakura.
