Blood Devil Research: Ryse/Yuuki

Not great at hiding what they feel. Yes, perhaps. But like the blood devil said, it was possible Nyx was beyond the point of being able to perceive even her own pain. Not that this made Ozaki feel any less ashamed for not knowing. He came here to learn. To understand.

Whilst Nyx was feeding on the blood devils he had managed to gather up all his blood in a puddle. He drained a blood pack of his own emergency stache, and manipulated the blood to collect into the now empty pack. If this was to Nyx’s tastes, might as well not waste it. Even if the mere act of collecting his own blood was making the bile rise  in his throat and his stomach twist. Ozaki took effort to hide his inner discomfort.

He tucked it away in one of his trench coat’s inner pockets, watching his healing factor get to work whilst listening to the woman speak. It was easier to look at his own wounds slowly stitch themselves back together than it was to look at her while being scolded like this for his ignorance.

A caretaker. Her father. He clenched his fist open and shut slowly, careful to not have his clawed hands cut into his palm. While the blood devil could not truly survive on the blood of a blood packet, perhaps having the right kind of blood might work. As he listened he modified one of his thoughts to perhaps this could work as one of the transitionary steps.

Was letting her drink the blood of a vampire actually a good idea though? The blood, when drunk by normal humanoid species, acted much like a poison. Killing and converting healthy blood cells. The undeath process was a lot less painful, and much more easy, when the victim was drained of blood first. But if they were full of it like Nyx was? That could be painful. Perhaps this would be a question he’d ask later. As much as it embarrassed him, he had to ask.

Drinking a vampire’s blood, even if it could work, didn’t seem practical though. And would his blood always taste so desirable to Nyx? Or did it have to be in a heated moment like this? If she were always drinking from him, that would mean he’d have to drink a lot more too. She had her blood producing venom. But how would that work in a person? Wouldn’t they bloat up or something? Perhaps not with how much a blood devil drank.

But drinking more would be worth it if Nyx got to eat, right? But would that be acceptable to the school for her to be drinking from him all the time?

And an instant emotional connection? Well they had some sort of connection at least. But emotionally bonding with every person you bit was a confusing concept. Particularly with a species that bit in battle as well. How could you fight like that? There was probably… Something. He was confused. But at least now Ozaki was getting the information he had wanted.

Ozaki’s mouth twitched slightly in mulling over how the blood devil had to hunt properly. That blood packs weren’t enough for them unlike other species. Heh… He himself did his best to throttle the instincts to bite down when he was in the midst of a hunt. And fact of the matter was he hunted just as much for himself as he did for the students of the academy. To sate the hunter’s instinct, the one that was always a bit let down when he did not devour his prey as it wished him to.

But he was fine living like that. He’d learned to manage his vampiric instincts and funnel them to constructive outlets. Ozaki would have to do the same for Nyx.

When she lied back on him he froze for a moment, before forcing himself to relax. It was fine. She was fed. And even if she did bite him, blood loss would technically not be enough to kill him.

The vampire followed as Nyx was lifted off him. He disliked how she was being handled, but for now he was going to be quiet. The last thing he wanted was to start another pointless fight that accomplished nothing. When she commanded them to sit, Ozaki did as he was told, sitting next to Nyx. He was wary of her, but he would not allow himself to show any such thing.

By this point he had straightened out his shoulders and was looking the red haired blood devil square on. That was enough of pouting like a child. He’d come here to learn. He reached into his trench coat and pulled out a small journal and pen, flipping to a blank page about three fourths of the way into it. Already he was quickly scribbling down what had already been said. Right now he was the student, and the blood devil his teacher.

So it was time to sit down, shut up, and listen. There was no room for his wrath or pride here on this couch.

Sitting on the couch she looked over at the other two, not yet quiet able to clearly put together what she had done to the other devils in front of them past the blur. Why did they almost looked spooked for a brief moment in time? She must have imagined it, while most were scared of her Mr.Ozaki hadn't been to begin with and Ryse had gotten over it upon learning she didn't fight. "It's odd feeling full for you, isn't it?" her head tilted when the red headed devil spoke up looking at her slightly. "I just kinda thought our kind was supposed to be hungry all the time, considering." Nyx spoke while she watched the older devil massage a clear substance into the neck of the human beside her, slowly remembering why she didn't feel hungry anymore as the seconds ticked by. "We can always consume more, we're essentially bottom pits, but after our nutritional requirements for a given day are met we don't feel hungry anymore." breaking in her speech the red devil sunk her fangs into the neck of her feeding partner closing her eyes while using one of her hands to support the neck of the human carefully, treating the other as if they were the most fragile thing in the world. 

Finally she realized what took place in order to finally remove the gnawing feeling of hunger she had felt for so long it almost felt as if that was normal. "I'm So Sorry!" her voice was small and slightly high pitched as she scooted backwards on the couch as if she could somehow vanish into it, averting her gaze from them. How had she lost control so badly? She had almost bitten Yuuki, if it hadn't been for the red devil she would have hurt him! "I don't know what came over me." she was almost squeaking as she got worked up believing he may hate her at this point for almost causing harm to him. "It won't happen again." she couldn't let that ever happen again, it wasn't worth not feeling hungry, loosing his trust wasn't worth it at all. "I'm sorry." her eyes lingered to the arm of the couch, refusing to face him, optics remaining closed even if she was still listening for the words of the older devil in regards to teaching all three of them about their species. 

"Continuing on the subject of food, we can control our age so long as we're properly fed. I have a feeling Nyx won't be able to control it for some time after her nourishment needs are caught up since she clearly has no experience doing it. So it's highly possible she will age at an accelerated rate." Since the red head didn't know the girls actual age it was impossible to tell how the small devil would age. "However, her body won't be able to make up for the damage that's already been done." the older devil sounded sad as she stated that walking over to Nyx placing a hand atop the small devil's head. "Even for one of us, she's far too small and that likely won't ever change even if her body may develop to an adults I don't see her height ever increasing and if it does the change will be minor, because her wings and tail likely can't grow anymore, if she's already a teenager it's just too late for them to grow. Pai come over here." when the other small devil came over she got Nyx and him to stand back to back, extending their wings out until both sets were fully open, encouraging both to hold their tails extended beside them fully. "Pai was malnourished when we first picked him up, thought for different reasons, now he's caught up and that makes him perfect for this demonstration. Look at their wings." Now that it was actually being called to attention? The shade of Nyx's wings seemed to be incredibly light due to Pai's, hers also appeared to be thinner than the males, and curled in slightly at the very edge whereas his stayed perfectly straight. "I'm actually surprised she can still fly. Now look at their tails." coming around to the side with the tails, grabbing Pai's her hand instantly dripped in blood having been cut by the sharpness of the appendage, yet when she used her other hand to grip Nyx's it actually gave way slightly under the hand and did no damage. Holding both hands up she continued once more. "You need to find a way to protect her tail until it's recovered from the malnutrition, no matter how many times we rebirth, this doesn't repair itself." she motioned for another devil to come forward away from their feeding, the other one lifting its tail to show that the shape at the tip the other's possessed was missing entirely. "Lastly, the horns. Kid, you need to stop bending them like this." as she spoke the red head manipulated Nyx's horns back to an upright position jutting out the side of her head, those horns were far darker than Pai's and seemed smoother than his as well. "It would be fine if they were healthy, but you're on the verge of breaking them you need to leave them in their natural position." she scoffed slightly guiding the smaller devil to sit back down on the couch again, Nyx clearly looking stunned. "Questions so far." the red head needed to make sure they weren't getting left in the dust. 

“Its alright.” He muttered to Ryse. She hadn’t known that that would be a bad thing to do. He didn’t want the other student to think that he was forgetting her… It was just there were a lot of important things going on right now.

He hugged Nyx to him, hesitant, but knowing she needed the comfort. “If you do that…” Ozaki padded where the breast pocket of his trench coat would be if it had one. It did… But it was on the inside, hidden. “I always have an extra packet of blood here on the inside of my coat. Just in case of any emergencies. Blood loss won’t kill me, it can’t. If you’re going to…”

He had to avoid said the word bite me. She, or one of these other blood devils, might take it as an invitation. “Loose control. Its… It’d be better if its me. I can drink the blood in my pocket here to replenish myself.”

She might have a picky diet. But Ozaki’s kind was far less selective in comparison. He wanted to comfort her, and the best way he saw to do that was to tell her why and how she did not have to fear loosing control of herself around him. While it would be best if she didn’t… If the only thing Nyx did was drink his blood, he’d be okay.

In hearing that it was much as a psychological thing as a physiological thing he took a note on that. It wasn’t just important to keep her stomach full but her… Heart full? That was cheesy as all get out.

And initially he thought that killing a blood devil for biting her might be extreme, at least until he heard the cultural context. It could basically be interpreted as kissing someone without their consent.

He gripped his pen tightly when she mentioned he played a paternal role. It was a little embarrassing to hear it said out loud like that. He glanced briefly to Nyx’s face to gauge any reaction to that, and bit his lip nervously as he looked back at his notebook.

When she started mentioning large and small blood bags a small ping of annoyance rang in him. That was not a standard unit of measurement. The heck was that supposed to mean? Nyx had just drained five, no, six blood devils of a shit ton of blood. That was the full amount that was usually taken from someone when they were doing traditional blood donations.

He’d ask her directly what she meant, but he didn’t want to interrupt and would rather have his own ballpark number to ask about when she finally came to a pausing point.

A pint of blood could be divided into two bags to be fed as the standard blood packs the school gave out.

The average human could only loose 40% of their blood before they died. Blood devils were clearly no average human, but he would go off of the numbers he had.

He was quickly writing various calculations. If the average human had about 5.5 liters of blood… Nyx had said once that her tail could hold 6 liters hadn’t she?

Anyways, he’d round it up to 6 liters for them and assume that the blood within the tail was not accessible to the rest of the body unless directly drunk from.

6 times .4 would be 2.4. 2.4 liters of blood times 6 for the amount of blood devils… Meant that on the low end she’d just drank 14.4 liters of blood.

About 4 gallons. If she weren’t clearly fine he’d be worried as hell right now. Even drinking too much water too fast could be fatal. And she’d just drunk four gallons of blood. Above all, it must be noted, Ozaki worked in inventory. And when it came to inventory, it was a number’s game. A game he liked to think he played well.

“Are you saying she’s going to need 14.4 liters of blood a meal?” That was a shit ton. … Oh wait. “I guess that’s not too bad. I’ll just have to make sure that I give her 1.4 liters, then allow enough room in the bag that it can expand to the amount she needs once the venom gets in there. If not 14.4 liters, I’m going to need a more precise measurement than large and small.”

When she passed out on him he froze, pupils going into slits. "What's happening?"

The red devil laughed whole heartedly as Yuuki spoke about an amount of blood more than double what their tails could contain being the average for what Nyx may need, snickering slightly at the end of her laughter. "No, it won't be easy to feed her but it won't take that much, you over shot by 4.4, meaning you only to secure a full liter per meal for her." it really added up but their venom made it far easier than it would be otherwise, she knew that personally. "But, that does need to exact, if her body gets too much it won't know what to do with the excess thus meaning that number will rise as it will simply decide to burn it, and if it gets too little than it won't put it towards recovery." feeding her own tiny devil was an absolute nightmare often times making her wonder why she had wanted to procreate in the first place as it was not exactly as if the species needed new children since they didn't die anyway. 

"Hey commander, our brat is hungry again." it was the male devil from before clearly recovered and slightly irate, holding a devil that looked to be only around a year old at best squirming between two hands. "Are You Trying To Break Our Daughter! Hold Her Properly!" quickly the red devil snatched the small fluffy haired child from the man and sat down with the infant on her lap patting the girls head. "Here sweetie." tone fond she moved her tail slightly using her blood manipulation to draw blood from it and direct it to the waiting mouth of the infant. "We're shockingly fragile when young. If you're wondering why I'm not just letting her suck it from my tail." quickly the infant was asleep on her lap and she drew the rest of the blood back into her tail, laying the girl down. 

Looking at the concerned duo she sighed slightly her head shaking calmly. "It's fine worry wort's, young devil's tend to pass out after eating their fill. Plus even if she's older than thought what just happened was emotionally stressful since she won't kill something she likely needed to shut down to recover from it." shockingly the male from earlier came over, draping a blanket over his daughters small body than placing one over Nyx as well. "What else do you want to know?" asking that once more she looked fondly at her daughter once more, patting the girls head.
