Merman Aventurine,,,, hngnhhhhggg save me savee me,,,,,,,,,

Full design + un-traumatised version + rambling under the cut <3

I imagine he's had bad experiences with humans. Think something like @/havanillas AU (I did draw a little inspiration from them, I'm not fond of Ratiorine but that AU was GOOD bro their art is gorgeous too), but I have a lot of my own takes. Probably very reluctant to ever interact with you if you're a human.

Only way I can see you meeting him is if your life is somehow at risk and he feels you will die if he doesn't intervene, plus it can't pose too big of a risk to himself. He's very cautious after first getting away from humans. Could be that your boat somehow breaks down at sea or something. Haven't figured out why he'd stick around yet though. Maybe he gets injured too after, and he has no choice but to ask for your help, however humiliating and scary it is.

Don’t fell pressured :)

Beneath the Waves, Beyond the Game

Summary: Aventurine, a flamboyant and cunning pirate, thrives on risk and games of chance, but his life takes an unexpected turn when he captures you—a mysterious, defiant being of the sea—after your haunting song lures his ship to wreckage. What begins as a clash of wills slowly evolves into a fragile bond, as shared vulnerabilities and unspoken understanding unravel the masks you both wear. Amid storms, trust, and bittersweet goodbyes, the game between the gambler and the mermaid changes them both in ways neither anticipated.

[Part 2]

Aventurine had always thrived on risk, gambling with lives, fortunes, and fate itself. The sea, for all its temperamental fury, had always been his ally—a rolling canvas of danger and opportunity. Yet nothing in his decades of games and gambles had prepared him for you.

You were sprawled across the floor of his private quarters, your tail shimmering with iridescent hues as seawater pooled beneath you. The moment he'd heard your song—a haunting melody that echoed through the mists and lured his ship to the wreckage of a treasure-laden galleon—he knew he couldn’t let you slip back into the ocean’s embrace.

You glared at him now, your once-melodic voice reduced to silence, replaced by a defiant scowl. Aventurine lounged in his throne-like chair, one leg crossed over the other, his flamboyant coat draped behind him like a cape.

"Do you make it a habit to lure ships to their doom, or am I just special?" he drawled, adjusting his jeweled eyepatch with deliberate flair.

You said nothing, your shimmering tail flicking once against the wooden floor, splashing droplets onto his polished boots.

He chuckled, leaning forward, the feather in his hat catching the low lamplight. "Silent treatment, is it? Fair enough. I've always enjoyed a challenge."

You clenched your fists, your lips pressed into a thin line. Your freedom was gone, and this man—this gaudy, insufferable pirate—seemed to delight in your captivity.

Weeks passed aboard the ship, and the game between you and Aventurine began in earnest.

He spoke to you daily, spinning tales of his exploits, offering you trinkets from his plunder, and even playing games of chance where the stakes were your freedom. You refused every gamble, your pride unyielding even as your curiosity grew.

In turn, you sang only when you thought he couldn’t hear—a mournful tune carried by the waves. But Aventurine always listened, his sharp mind piecing together fragments of your story.

"You sing of loss," he said one night, his voice unusually soft. He stood at the door to your makeshift prison, his silhouette framed by moonlight. "Of betrayal. You’ve felt it too, haven’t you?"

You flinched at his words but said nothing.

He stepped closer, his voice dropping to a near whisper. "You think I don’t know what it’s like to be trapped, to have your fate decided by others?" He tilted his head, his eyes glinting like twin flames. "But I broke free. And so will you—if you’re clever enough to play the game."

For the first time, you spoke. "You don’t understand the sea’s bindings, pirate. My freedom isn’t yours to give."

The slow burn of trust began with small acts. Aventurine loosened your chains, allowing you to roam the deck under guard. You, in turn, offered him warnings of treacherous waters ahead, saving his ship from disaster more than once.

"You’re not like the stories," you admitted one evening, your voice hesitant.

"Flattered," he replied, grinning. "But you’d be wise to keep your guard up. I play to win, and I always do."

"Always?" you challenged, meeting his gaze.

His grin faltered for the briefest moment, but he recovered quickly. "Luck’s been kind to me so far."

Yet you saw through his bravado. Behind the jewels and theatrics was a man haunted by choices, a survivor who carried his guilt like a hidden scar.

The breaking point came during a storm. The ship was battered by relentless waves, its crew scrambling to secure the sails. Aventurine himself took the wheel, his usual calm replaced by a rare intensity.

When a rogue wave threatened to sweep you overboard, he abandoned his post to pull you to safety, his hand gripping yours with a desperation that surprised you both.

"Don’t you dare die on me." he hissed, his voice cracking.

For the first time, you saw him without his mask—a man terrified of loss.

The aftermath of the storm left the ship battered but intact. Aventurine found you sitting on the edge of the deck, your tail dangling in the water.

"You saved me..." you said softly.

He shrugged, his usual grin forced. "Couldn’t let you take all my secrets to the deep, now could I?"

But you weren’t fooled. Slowly, you reached for his hand, your touch tentative but firm. "Thank you."

He stared at your joined hands, his guarded expression faltering. "You’re not supposed to thank me," he muttered. "I’m the villain here, remember?"

"Villains don’t bleed for their captives," you countered, your voice steady.

The ending was bittersweet.

Aventurine kept his promise, releasing you near a hidden cove where the sea glittered like liquid sapphire.

As you slipped into the water, you turned back one last time. "You’ll always be playing, won’t you?"

He smirked, though it didn’t reach his eyes. "What can I say? The game’s the only thing keeping me afloat."

"Then I hope you win, pirate." you said softly, your voice carrying the weight of unspoken understanding.

And with that, you disappeared beneath the waves, leaving Aventurine standing alone on the shore, the ocean stretching endlessly before him.

Do stay alive. I wish you the best of luck.

I imagine that after Merventurine goes back to the ocean in the future, Ratio will find himself still making two servings of cooked, seasoned tuna for days. He'll convince himself it was for the best, and in the same train of thought turn his gaze towards the sea just in case. Hence, I named this piece Reluctant Farewell.

Brrt don't know how to paint caustic effects on underwater skin yet.

Thanks again to the man, the myth, the spoinky, @havanillas for providing us with brainrot good food for this AU.

Hear me out. Ratiorine AU where Aventurine is a mer captured by a group of researchers and Ratio is the scientist brought on board to teach him how to speak and access his intelligence levels.
