The alley was a gash of shadow between two opulent merchant houses in Astraea's royal district, a place where the city's glittering facade peeled back to reveal the rot beneath. The air, thick with the scent of spoiled wine and damp stone, was suddenly pierced by a sound both alluring and utterly out of place: a woman's soft, melodic humming.
She was a vision of impossible beauty, leaning against the damp brick wall. Her hair was the color of midnight, her eyes twin pools of liquid starlight that seemed to promise secrets and solace. Cowering before her was a boy, no more than nine, his fine silk clothes marking him as minor royalty. Tears streamed down his face, but he was frozen, entranced.
"Shhh, little prince," the woman cooed, her voice a silken trap. "Don't be afraid. I have a gift for you. A sweet to make all the fear go away."
From the folds of her dress, she produced a single, crystallized berry that glowed with a faint, hypnotic purple light. Paralyzed by fear and her unnatural allure, the boy could only watch as she gently placed it on his tongue. His eyes widened for a second, not in pain, but in surprise at the burst of sweetness. Then, a profound lethargy seized him. His limbs locked, his breathing slowed, but his mind remained horrifyingly aware, trapped inside a frozen shell.
The woman's beautiful smile never wavered. She leaned forward, her humming resuming, a gentle, cruel lullaby as she deftly unclasped a delicate, moonstone pendant from around his neck. She studied it for a moment, her starlit eyes glinting with satisfaction, before tucking it away.
"A necessary key," she whispered to the paralyzed boy, her voice now devoid of all warmth, flat and ancient. "Your sacrifice is noted."
Then, she simply turned and walked towards the solid brick wall at the alley's end. She did not open a door or cast a spell. She stepped into the wall, her form dissolving into the stone as if it were mist, leaving no trace behind.
Seconds later, the thud of armored boots echoed through the alley. Two royal guards, summoned by a servant's worried glance, skidded to a halt. Their lanterns illuminated the scene: the small, rigid form of the boy, his eyes wide with terror, a single trickle of purple-tinged drool leaking from his lips.
One guard rushed to the boy, checking for a pulse he knew he wouldn't find. The other scanned the dead-end alley, his face a mask of confusion and dawning horror.
"There's no way out!" he stammered. "How… who could have…?"
The first guard looked up, his face pale. He had seen the reports, the whispers that circulated among the higher ranks. A killer who left no trace, who could walk through walls, who stole specific, seemingly random artifacts.
"It's them," he breathed, his voice trembling. "It was… Nox."

The noise of the grand Adventurer's Guild hall in Astraea was a comforting cacophony after the silence of the road. Sarah and Kenta approached the registration desk, a massive slab of polished oak manned by a wizened old elf whose eyes held the weight of countless assessed adventurers.
"Names and proof of rank, if you have it," the elf said, not looking up from his ledger.
"Sarah Yamazaki," Sarah said, placing her guild card from a previous, smaller town on the counter.
The elf picked it up, his bored expression suddenly sharpening. He tapped the card with a crystal, and runes flared across its surface. His eyebrows shot up towards his hairline. "UR? Verified. That's… that's a first for a walk-in." He looked at her with newfound respect. "Your fame precedes you, Miss Yamazaki. The tale of Gelber's liberation is on every merchant's tongue."
He then turned to Kenta. "And you, sir?"
Kenta silently placed his own, more worn card on the counter. The elf repeated the process. The runes flared again, this time glowing with a unique, alternating pattern of silver and deep grey.
"UR… UR+?" the elf stammered, his professional composure completely shattered. He looked from the card to Kenta's calm face, then back again. "Dual-affinity registration? By the ancient groves… Forgive my astonishment. We are honored to have you both. Your combined rank grants you access to the platinum-tier quest board and all associated privileges." He handed them new, intricately embossed platinum cards, his hands shaking slightly. "Welcome to the Astraea Guild."
The weight of their new status settled on them as they left the guild hall, the city sprawling before them. The urgency of their mission was a constant drumbeat, but for the first time in what felt like forever, they had a moment of peace, of safety.
"So," Sarah said, a playful smile touching her lips. "We're officially famous and terrifying."
"It seems so," Kenta replied, a faint smile of his own appearing.
"I think we've earned a day off," she declared. "A date."
Kenta blinked. "A… date? Is that a type of mission?"
Sarah laughed, the sound bright and clear. "No, you dummy. It's from my world. It's when two people who… care for each other… spend the whole day together. Just enjoying each other's company. No fighting, no training. Just… living."
The concept was foreign, almost bizarre to Kenta, whose life had been defined by survival and vengeance. But the hope in her eyes was something he found he couldn't refuse. "Very well. A… date."
The day unfolded in a series of simple, profound moments. Sarah, with a keen eye honed by her System's analysis, dragged him into a tailor shop and insisted on buying him new clothes. She chose a set of dark, practical but well-tailored trousers and a tunic of deep blue that made his calm demeanor seem more regal than brooding.
Later, it was his turn. He led her to a quiet street of artisans, his payment from Gelber heavy in his pouch. He stopped before a jeweler, his gaze fixed on a delicate silver necklace from which hung a single, teardrop-shaped moonstone. It wasn't flashy, but it was elegant and strong, much like her.
"For you," he said, his voice quiet.
Sarah's breath caught. It was the first gift anyone had ever given her that wasn't a tool for survival. She let him fasten it around her neck, the cool stone resting against her skin feeling like a promise.
They spent the rest of the day wandering the city's vibrant markets, sharing strange foods, and simply talking. They spoke of trivial things—the taste of spiced honey cakes, the absurdity of a street performer's act—and in doing so, they built a new foundation. It wasn't the bond of comrades-in-arms, but something softer, more fragile, and infinitely more precious.
As the sun began to set, painting the crystalline spires of the Grand Arcanum in hues of orange and purple, they stood on a bridge overlooking a canal. The weight of the world—Hiragi, Khazad, the mysterious Nox—was still there, pressing in from the edges of their consciousness.
But for one perfect day, they had chosen to live not as weapons of war, but as a boy and a girl, discovering a new world and each other. The memory of it, of the moonstone against her skin and the feel of new clothes on his, would become an anchor in the storms to come. The date was over, but the connection it forged had just begun.
