Regret was a rather new thing for a Satan to experience. He hadn't regretted overthrowing the Old Satan Faction, nor the enumerable death that had occurred. The rot needed to be cut out for all of Devil kind to flourish without being held back by archaic traditions that only held them back, especially since every other faction had begun to change and evolve even back then. He'd never regretted tossing aside his old family name and the consequences that followed, his parents were young enough to have another heir so there was no worry of the Gremory Household vanishing. Hell, he hadn't even regretted taking on the mantle of Satan, sure the work might be mind numbing but even with all his joking there honestly wasn't another job he'd want to be doing.
Sirzechs should've never let his wife, the love of his life anywhere near that monster. He shouldn't have let her convince him to allow her to take their son with her. If the Satan knew something like this was possible, he would've told her to hold off on the assassination. They should've waited, observed the nature of the old monster and look out for weaknesses to exploit...but it seems their own nerves and over-confidence in that damned needle had come back to bite them.
Malevolent crimson energy flickered at his finger tips, crackling silently as it devoured even it's own sound waves. It was easy to grow so complacent, especially when this exact set up had worked on so many Ancient Senjutsu Practitioners in the past. Not all of them were too keen to move forward to the new world order, so they had to be dealt with promptly for the good of the world.
They'd never tried use the Final Sting on an old monster, as most of them died of natural causes before they even needed to lift a finger but there shouldn't have been a reason why it wouldn't work on them as well. What a fool they'd been. Too arrogant in their own ways and far too trusting of the word of outsiders.
He'd been all to happy to have his own Ancient Senjutsu Practitioner under his thumb and had at the time, allow them free reign to experiment with the manuals they'd confiscated and possibly improve a few of them over the century. It had paid dividend and more when they enacted their modernized version of Senjutsu designed to reach an uncross-able plateau.
That power should've never reached human hands in the first place, look at what they'd done with nothing but pieces of metal and water.
"Satan Lucifer."
A nearby servant bowed at their waist to him, their magical field fluctuation around them as they faced off against one of the most powerful Devil's in existence flickered in direct opposition to their cooled and collected expression. Each of them wore pure white scrubs that hugged their selves in a way that maybe, maybe would've convinced him to pick one up for his wife. But if anything, such thoughts were far from the forefront of his mind….okay, maybe he could at least ask where they got them from.
"Lord Sitri will see you now."
The same servant spoke in a quiet voice, their internal shaking growing in ferocity as they were unconsciously stared at by their over arching ruler. Without his characteristic grin anywhere in sight, he swept passed the gaggle of servants and made his way down the sterile white hallway. The sound of rubber soles squeaked slightly with every hurried step, all he passed paused in place and stepped to the side while bowing deeply at the waist.
Honestly, it probably would've looked as though he was some sort of CEO like in those Korean romance sitcom shows his wife…
Fists clenching, just like that he had been dragged out of those happier times. And instantly, every other occupant scattered out of view. Some even going as far as to hide in nearby rooms or outright jumping out windows to begin flying away.
"I would appreciate it if you didn't scare away our staff."
"My apologies, Lady Sitri." He didn't even need to look to his side to know who had the courage to chide him in his current mood. But from the corner of his eye, he saw an almost direct copy of his fellow Satan with just a different air of maturity. Her long black hair was tied up in a tight bun, with deep violet eyes behind a pair of arms glasses that clung to the bridge of her nose. She wore a simply white lab coat over a bright blue button up shirt. "I did not mean to throw your hospital into chaos, I am sure you can understand me being worried about my wife….And thank you again for seeing us on such short notice."
"I do understand," Lady Sitri nodded once, her tone becoming a tad bit warmer but still kept that professional distance. "But, please keep yourself under control. You are not the only residents here and your aura could have a negative impact on some of our patients despite the wards in place. Please follow me, I will guide you to your wife's room."
And with that, the pair fell into silence. Not even their breathing could heard as they went down a variety of twists and turns, passing many rooms occupied by nurses and their charges. Some groaning, so screaming and even some snoring could all be heard through their heightened senses. Before long, they stopped in front of a single room. A large golden plate on it's side signified it's VIP status. Knocking thrice, the Devil waited heartbeat before slowly opening the door much to leisurely for Sirzechs's liking. Despite wanting to just push past the doctor, he restrained himself.
This wasn't his home and these people had taken the time out of their day and pushed his issues ahead of many who would kill to be healed by House Sitri personally. The least he could do was not piss off a fellow Satan's family.
Entering the room, two people became visible to his sight. One, a tall and slender man with neatly cut black hair and bright violet eyes that glinted slightly behind a pair of glasses that everyone knew were strictly only useful aesthetically. The man wore a matching lab coat with a pure white button shirt underneath, a stethoscope draped over his shoulders.
But that wasn't what captured his attention, just an arms length away laid his beautiful wife. Her silver hair laid out behind her in a rare display, making her look like she just stepped out of a story book. As though she was waiting on her true love's kiss to cause those still eyelids to flicker open. But this was no fairy tale, no matter how much he wished it was so.
Grayfia has always had pale skin, most Devil's did but hers even more so. But now, instead of that healthy gloss he enjoyed looking at so much, it was like a sheet of paper was layered over-top her. As though a simple poke would rip through her flesh. And her face, oh her gorgeous face had a sallow and withdrawn appearance about them. Those lips once so plump and red, were cracked and pale.
If anything, she looked worse than when he first scrambled her here.
"Greetings, Satan Lucifer." Lord Sitri, the head of House Sitri and multiple hospitals across Japan, nodded gravely. His voice calm and holding that same professionalism that his other half possessed. "To get right into it, your wife is stable. The procedure was a success...but that's the problem, we can get it that later. Her trickling life force has been plugged temporarily until you've come to a solution. We treated both her broken arms, reconstructed her shattered hip, regenerated a few organs and even realigned her spine… It seems Lady Lucifuge still had enough demonic energy to keep everything in place until she got here, a good thing too or this would've taken a lot longer and possibly would've brought up a multiple complications…"
"But that's where the good news ends." At this, even the cool and collected doctor looked a tad bit reluctant but with centuries of experience, his expression schooled into something neutral. "We could not regrow your wife's wings… Whoever tore them out, made sure not even a bit of flesh was left behind. While if some had been left behind, they would barely function as anything but ornamental objects. Her lost has also resulted in her demonic energy pool dropping to below that off a newly recruited Devil...a pawn at that. It wouldn't be so bad, with her knowledge and connections, it would be easy to spend the next century or so recovering her strength but that's thing, it wasn't just her physical wings torn out. They were ripped out on a conceptual level, on her very own soul...meaning, they will not come back. Her strength will never recover and she'll forever be at this level."
