Summary
Normally Aventurine was so good about this sort of thing. A vampire in his position had to be if he wanted to get away with just living, let alone thriving the way he did. If he was hungry, he’d go pick on a stranger. Strangers were so much easier to get his fill from, given the lack of any meaningful connection, and since so much of his work was off-world and for the IPC, it wasn’t like anyone could hold him for long if things didn’t go perfectly.
Yet here he is now, falling to the classic blunder of a handsome, familiar face inviting him inside “just until his cab comes.” I’m getting indulgent, he thinks, as he crosses the threshold with a charmed smile and glittering eyes. When he sees Veritas slipping off his heavy overcoat again, he decides he doesn’t care. If Aventurine hadn’t been invited in, he’d call it unfair for an academic of Ratio’s renown to also be such a striking specimen of the human muscular system.
-----
After an otherwise successful date, Aventurine is invited into the... minorly eccentric flat of Dr. Veritas Ratio, where his ability to wait until later to feed is tested by Veritas' Pure Autistic Swagger (barely kidding) -
You Again, Doctor? by AracelysDelusion for ghostphone

Summary
Ratio looked over to Jade's side to see a man with blond hair, bejeweled eyes, and that same branding on his neck he had been unable to forget for the last Amber Era staring straight at him.
Even the man looked surprised for a second before his expression melted into a shit-eating grin that gave a brief glimpse at his sharpened canines.
You have got to be kidding him.
“Oh? Do you two already know each other, doctor? Well then that makes the process much easier,” Jade spoke up, "I would like to introduce you to the Stoneheart’s newest member, Aventurine. You two will be working together for quite some time, so get comfortable."
OR
Ever since dying and reviving himself through sheer will, Ratio has known immortal life to be long and painfully monotonous. That is, until he keeps encountering the same blond man across entire lifetimes, unchanged, irritatingly charming, and very much alive.
When he finally meets that mysterious man again, now a Stoneheart at the IPC and his assigned partner, Ratio is dragged into a friendship, a feeding arrangement, and countless new variables he never experienced before in five Amber Eras of existence.

Ephemeral Blood, The Avgin Feast by ExoticAlmonde
Fandoms: 崩坏：星穹铁道 | Honkai: Star Rail (Video Game)
01 Nov 2025

Summary
Aventurine, of a rare vampiric race called Avgin, finds himself utterly intoxicated in an attempt to bear through the ball Jade and the Stonehearts had organised. Through the haze he vaguely notices a handsome man - a stranger who came for the aftermath of his feeding - quietly throwing concerned glances in his direction.
Despite all demands of propriety, he couldn't let that person go. He had to follow.
And like a moth to the flame, he threw himself into the inferno, begging for a drop of warmth in the cold world he existed in. -

Summary
There are a lot of rumors surrounding vampires, and Aventurine in general. That he’s constantly got someone, some customer under his thrall, is one of them. That his eyes can hypnotize. Ratio refuses to believe it, but when Aventurine merely looks at him when Ratio finishes his tirade on the dangers of love potions, all he says is;
"I know."

Summary
For the 2025 halloween exchange!
Prompt: AU where the Avgins are secretly vampires. Ratio somehow finds out, at first Aventurine thinks this is what’s going to make their friendship(?) crash and burn but Ratio is like: I need to know what it feels like to be drank from… for science. By the end, not only is their friendship not destroyed but actually levelled up to boyfriendship(?) Aventurine is very confused about how they got here but he’s not going to complain about having a hot boyfriend and a very delicious source of food at the same time.

Caught Between Your Fangs by Grimour (OmniaImmortalis)
Fandoms: 崩坏：星穹铁道 | Honkai: Star Rail (Video Game)
23 Oct 2025

Summary
It was a cold, cloudless night. The moon's eye cast its gaze upon the succubus, having climbed atop one of the large trees near a cracked window of a manor he'd spotted. It looked a bit run down – if a noble lived in it, they ought to be from a house in decline. Good. Less guard dogs to sneak around, less chance of a butler storming in.
Veritas swallowed, the fatigue of not having been satiated in far too long laying heavy upon his limbs. Black, clawed nails dug into the branch he was squatting on, kept him stable as a rush of wind whipped dark hair onto his face.
The only sign of life was the smoke steadily rising from the chimney on the roof; not a single lantern had been lit, and most of the windows were tightly shut, heavy curtains keeping Veritas from looking in.
Veritas, a starved succubus, seeks his next sustainer and ends up somewhere he never would've expected.

Summary
Professor by Day. Hunter by Night.
Dr. Ratio is a brilliant University professor who serves the Church as one of its most efficient vampire hunters and researchers.
His orders come directly from Sunday, the youngest ever to lead it, who's polite, composed, and utterly merciless toward anything with fangs.
And then there’s Aventurine. His brightest, most aggravating student.
The one with the quick smile, sharpe mind… and a secret that should have damned him long ago.---------------------

Summary
“What the hell are you?!”
“Veritas, calm down.”
“Don’t call me that! What did I just see?! Did you do the same thing to me?!”
“Relax.”
He thinks about the metallic smell and taste of the wine he had earlier.
“You made me drink blood!” He quickly backs away from Aventurine, falling backward as he does so before he scrambles to back away from him on the floor until his back is pressed up against the wall.

Summary
The night was pitch black, without even a moon to guide one the way back home, but that hardly meant that the area was lifeless. No, the wrong type of life, the one that refused to be sent to permanent rest, flourished here. (Humanoids just a bit too perfect, a bit too collected, made the night their hunting ground.)
Or: Vampire Aventurine eats out Ratio whilst he's on his period. And asleep.

Summary
Aventurine thought he could go without a blood supply for a couple of days, but little does he know that he’s about to be stranded on a strange planet with only Ratio to keep him company.
He’d sworn never to feed directly from a human, but even the strongest of wills can be broken by hunger, and Aventurine will have to embrace his hunter instincts or suffer the consequences.
In which vampire Aventurine partakes of Ratio's blood.

Summary
It all happened when a famed researcher was at the end of his wits.
The world bore witness to a plague. It took the population by storm. Though not contagious, the infection spread indiscriminately across approximately ten percent of the populace. It ended as soon as it had started—the ten percent were kept under constant surveillance, but there appeared to be nothing to halt the rapid spreading of the virus through their bloodstream.
“Mr. Aventurine. Do you happen to be the vampire of rumors?”
Aventurine paused. Ratio expected him to burst into a fit of laughter and dismiss those rumors with a sensible explanation.
What he hadn’t expected was for the man to lean close, invade Ratio’s personal space, and ask, “If I say yes… what’s in it for me?”
And thus signaled the start to an incredibly unconventional partnership between a human doctor and a cunning vampire.

Summary
Aventurine thought it would be just another night at the club—just another hunt for blood and lust. It was supposed to be a one-night stand, maybe a name he’d forget by morning. He didn’t expect to get tangled up in a deadly game with someone who was meant to kill him.
