Aventurine

The warm light of the floor glimmered off Aventurine’s rose-tinted glasses as he sat in his office, shuffling a deck of cards with practiced ease. The quiet knock at the door didn’t faze him; he expected one of his assistants.

“Come in,” he called, but the door remained shut. His brows furrowed. “Hello?”

A muffled meow answered, faint and uncertain. He rose, smoothing the fur trim of his coat before opening the door, only to find nothing. Another meow had him glance down, where a kitten with fur as soft as his fur trim stared up at him, eyes wide with urgency.

Aventurine crouched, an intrigued smile curling his lips. “Well, aren’t you a peculiar little gambler?” he mused, reaching out to pick up the kitten. It immediately pawed at the rims of his glasses, tugging them slightly askew.

“Hey now,” he chuckled, “those aren’t a toy.” But as the kitten batted at his bracelet with a strangely familiar persistence, realization struck. His smile faltered, replaced by genuine shock.

“...Wait. Is that you?” he whispered, his fingers brushing over your tiny head. The kitten’s insistent nod and another urgent meow confirmed it. Aventurine’s laughter broke the tension, a mix of amusement and disbelief.

“Well, love, you’ve really raised the stakes this time. Don’t worry,” he said, cradling you against his chest, “we’ll figure this out. But first—how do you feel about poker?”

Sampo Koski

The merchant whistled a jaunty tune, inspecting his latest haul in a dimly lit backroom. A soft thud made him pause, his eyes darting to the source. There, amidst the scattered goods, a small kitten struggled to climb out of a wooden crate.

Sampo knelt, laughing under his breath. “Aw, did I accidentally ship you in a box? Poor little one.” He scooped you up, but froze as the kitten squirmed, reaching for his face with a familiar urgency.

“...Hey, wait a second,” he muttered, narrowing his eyes. The realization hit when you swatted his nose with deliberate intent. “No way. Is this some kinda joke?”

You yowled, smacking at the silver cuff on his ear. Recognition dawned, and Sampo barked out a laugh so loud it startled you.

“Well, well, this is a twist! You’re cuter than I expected,” he teased, holding you up to eye level. “Don’t worry, I’ll fix this. For a small fee, of course. But hey, this could be great for business! Ever heard of the world’s only scammer cat?”

Dr. Veritas Ratio

The library was quiet, save for the soft rustle of papers and the occasional sigh from Ratio as he poured over ancient texts. He was lost in thought when a soft thump on the table pulled his focus.

There, atop his meticulous notes, sat a small kitten, staring at him with an intensity that rivaled his own. Ratio’s eyes narrowed. “What is this nonsense?”

The kitten didn’t back down. Instead, it batted at the straps of his arm braces, its persistence strikingly familiar. Ratio tilted his head, studying you with growing suspicion.

“You’re far too bold for a common feline,” he remarked, leaning closer. “Those eyes… Wait.” His tone sharpened. “Is that you?”

You responded with an annoyed meow, pawing at the jewel on his vest. Ratio’s brows furrowed, a rare flush of embarrassment coloring his cheeks.

“Unbelievable,” he muttered, pinching the bridge of his nose. “First, ignorance plagues the universe. Now, this. Fine. Stay still while I calculate a solution—and stay off my notes.”

Jing Yuan

Jing Yuan was enjoying a rare moment of leisure, sipping tea. A soft meow interrupted the peace, and Jing Yuan turned to find a small kitten attempting to climb him.

“Well, what do we have here?” he said, his eyes warm with amusement. He gently picked you up, cradling you in his hands. “A brave little one, aren’t you?”

As you squirmed, pawing at on his hip, Jing Yuan chuckled. But then he noticed something—your eyes.

“...No,” he murmured, his smile fading. “Can it be?” When you gave a frustrated meow and nuzzled his palm, recognition bloomed.

Jing Yuan sighed, stroking your tiny head. “Ah, so this is what has become of you. How unfortunate.” He set you down gently, his calm demeanor masking his concern. “Worry not—I’ll ensure you’re returned to your proper form. But for now, consider this a lesson in humility, my small friend.”

He leaned back, a soft smile returning to his lips. “Though I must admit, you make a rather adorable kitten.”
