The corridor opened with a muted hum, spitting out a figure onto the sand with the least grace imaginable.
Demyx stumbled through the mist, nearly tripping over his own boots as the swirling darkness sealed behind him. He caught himself on his sitar, muttering, "Smooth landing, ten outta ten. Real dignified entrance."
Sea mist drifted across the beach like smoke, hiding everything beyond a few yards. The world smelled clean — too clean. Salt, rain, and something ancient still clung to the air, like the ghost of a melody.
"Ughhh… water, water everywhere, and not a lounge chair in sight," Demyx groaned. "Who do I gotta charm to get a dry recon job for once?"
He sighed dramatically and tapped the strings of his sitar. Ripples of water lifted from the damp sand, coalescing into three small, translucent figures — exact watery copies of himself, only quieter and far less sarcastic.
"Alright, my loyal minions," he said, gesturing with a flourish. "Fan out. Check the coast, check the ruins, check for anything glowing ominously or humming like a bad remix of destiny."
The clones saluted silently and slipped into the fog like obedient currents.
Demyx stretched, yawning so hard his eyes watered. "Man, I should've faked being sick. 'Sorry, Xiggy, can't go on the ocean mission, got a—uh—heartburn.'"
He chuckled at his own joke, then frowned. "Wait. Hearts. Ugh, bad pun. My bad."
He trudged forward, boots squelching against the wet sand. Every few steps, he flicked his fingers across the strings, sending faint soundwaves rolling through the mist. The sitar's tune wasn't random — it was a probe. Each note sent vibrations into the water, mapping the energy in faint harmonic feedback.
The sounds answered.
Soft tones returned to him — dissonant, incomplete. The kind of sound that felt like an echo of a lullaby half-forgotten.
Demyx frowned. "That's not creepy at all…"
He adjusted a dial on the instrument, his casual posture hiding the fact that he was, in fact, a skilled recon specialist. Each vibration painted a picture in his mind — pulses of residual energy, data shaped as sound.
"Subject T-F…" he muttered under his breath. "Heart fragments show dual polarity. Potential for Nobody extraction: High."
He paused to record the line into a small crystal communicator strapped to his wrist. His voice dropped into the kind of professional tone he only used when someone higher on the food chain might listen later.
"Observation: world re-stabilized post-divine restoration event. Fractured heart energy remains active. Recommend continued surveillance for emotional fluctuation. Also, humidity level: one hundred percent. Ew."
He stopped at a cluster of blackened coral jutting from the sand. The coral pulsed faintly, green veins running through it like veins of light. Demyx crouched beside it, brushing his gloved fingers along the surface.
"Residual life magic," he murmured. "Pretty, but definitely not natural or useful."
The sea breeze shifted, carrying faint laughter from somewhere inland. He turned toward it, squinting through the fog.
Up the hill, through the trees, three figures moved — faint silhouettes framed against the horizon.
He adjusted the volume dial on his sitar, plucked a single sharp note, and the sound focused like a lens. The mist blurred away from his line of sight.
There they were.
Skuld walked ahead, her blue coat fluttering with every step. The air shimmered faintly around her — soft, radiant, alive. The light clung to her like a promise.
Beside her, Moana carried herself with confidence born of familiarity — every motion in rhythm with the sea. She was mortal, yet her heart resonated like the waves themselves.
And then there was Kurai.
Demyx's tune faltered.
The woman moved with poise that didn't belong in the light. Shadows followed her like obedient pets. Her aura wasn't darkness in the usual sense — it was structured, deliberate, like she'd tamed it rather than succumbed to it.
"…Whoa," he whispered. "That's… new."
He strummed a few experimental chords, sending out harmonic pulses. Skuld's light responded with warm tones, Moana's heart resonated steady and rhythmic — but Kurai's aura? It didn't echo back. It absorbed the sound entirely, swallowing it into silence.
Demyx shivered. "Note to self: do not sneak up on the scary lady."
He lifted his communicator. "Report to Xigbar: Target world stabilized. Divine fragment unaccounted for. Potential Nobody core detected. Team of outsiders present — likely what you told me keyblade wielders. Multiple light signatures detected. One anomalous shadow aura deflects sound readings."
A click came through the comm — followed by Xigbar's lazy drawl.
"Heh. Always the fun assignments, huh, kid? As if."
"Yeah, 'fun' is one word," Demyx muttered. "Hey, uh, if this is about another experimental project, maybe you could, you know, tell the boss I'm better suited for indoor missions?"
"As if," Xigbar replied, amusement dripping from every word. "You've got the right touch for this kind of work. Just keep those strings in tune, and try not to get vaporized."
The line clicked off.
"Great pep talk as always, Xiggy," Demyx sighed, pocketing the communicator. "Couldn't send, I dunno, Saïx or the boss himself? Nope. Let's send the musician who hates cardio."
He leaned his back against a coral ridge, the sea mist swirling around him again. His water clones reappeared one by one, each presenting what they'd found: sketches of energy trails, faint traces of Heartless residue, and… something else.
One clone dropped a fragment of obsidian glass into his palm. Inside the shard, light shimmered faintly — green mixed with black.
Demyx turned it in his hand, frowning. "You're still out there, huh? The fragment the big rock lady lost…"
The shard pulsed faintly. For a second, it seemed to hum in response to his voice.
"Okay," he said, staring at it, "that's not ominous at all. Not talking to cursed glass today, thanks."
He tossed it into the shallows, but the moment it touched the water, a ripple spread across the surface. It moved far too fast — racing outward in concentric circles that carried a low, melodic resonance.
The ocean sang back.
A soft note vibrated in the air, perfectly in tune with his sitar.
Demyx froze. "Wait a second…"
He plucked a string again. The same note echoed back — slower, deeper, distorted, like the ocean itself had learned to mimic him.
"Okay. That's… mildly terrifying."
He grinned nervously, backing up a step. "Hah, cool trick though! Totally not haunted! I'll just, uh, mark that as 'acoustic anomaly' and get the heck outta—"
The ripple passed under his boots. The sand trembled. For a heartbeat, he could swear something massive turned beneath the surface — an ancient rhythm brushing against his own melody.
Demyx's grin faded. "Right. Definitely haunted."
He scrambled up the coral ridge, shaking the water from his gloves and brushing back his hair. From up high, the view was almost serene — the island bathed in sunlight, waves glimmering, peace restored.
Almost.
He sat down on the ridge and pulled his sitar into his lap. His fingers drifted over the strings, plucking lazily, half out of habit, half out of nerves. Each note shimmered into the air, rippling faintly across the water.
"Guess the others will catch up sooner or later," he murmured to himself. "Maybe I'll even get hazard pay this time."
He strummed another chord, soft and aimless. The melody floated outward like a lullaby — calm, lonely, familiar.
The water rippled again.
Something deep beneath the waves strummed back.
The two melodies intertwined, faint at first, then almost harmonious — like two voices remembering a song they used to share.
Demyx froze, hand hovering above the strings. His reflection on the water wavered — and for just a moment, it wasn't his reflection at all. A face of flowing water and hollow eyes stared back up at him.
He blinked, and it was gone.
He swallowed hard, forcing a crooked grin. "Yeah. Totally fine. Just the acoustics messing with me."
He leaned back, strumming again — lighter this time, trying to mask his unease. The melody drifted across the sea as the mist began to close in once more.
