The latest makeshift habitat, shiny and resplendent amidst the sunlit coral banks, seemed about ready for use. Though, as Kazuma and Aqua fought to clear the portcullis and be the first aboard, there was Megumin sitting in the main hub, blithely flipping a company-issue pocket lighter. She appeared to be shivering a bit.
Aqua, working off the lingering electric shock from the SeaMoth, courtesy of Darkness, pushed forth to feel Megumin's forehead, which the junior tech allowed without fuss. "The power's out," Megumin affirmed despondently, eyes tracking the occasional glint of fauna flitting between the submerged sunbeams at roughly their level.
"Well, I just so happen to have some power cell--" Aqua paused, checking her inventory, her eyes widening a bit.
Everybody turned as one to find Darkness, via video feed, waving cheerily, as she finished recoloring the loaned SeaMoth, swapping in Aqua's personal stock of Power Cells, and took off with a celebratory 'yip'.
Sighing, Kazuma zipped up his diving gear and headed for the nearest hatch. "Guess I'll scrounge up some more copper ingots."
Megumin, knowing the great lengths they all went to secure the last load, smirked good-naturedly.
Above, as the twin moons shone bright across the surface of the ocean, barring full view of the usual smattering of stars stretched out like a velvet tapestry, a staunch counterpoint to the tranquility was playing out in the waters somewhat removed from the claustrophobic confines of their base.
Though, cleverly, it was operating a few decibels shy of the lurking horrors below, not keen on drawing that much attention. For all they knew, it was mating season.
Despite being out for that long, Kazuma hadn't the foggiest idea as he wrapped up his copper-hunting expedition and returned through the airtight threshold, mask already pulled down around his neck and seawater dripping from his hair in a rhythm that matched his exhausted breathing. "Three hours," he wheezed, dropping a pathetically small pile of copper ore onto the fabrication table. "Three hours in that kelp forest with those... those
things watching me from the shadows, and this is all I could find."
Megumin glanced up from her meticulous arrangement of data cards, eyes gleaming with the particular brand of manic energy that typically preceded disaster. "You mean the Stalkers? I've been cataloging their hunting patterns. Did you know their teeth can be used as fabrication material? All we need to do is—"
"No," Kazuma interrupted, holding up a dripping hand. "Whatever scheme involving explosions and 'controlled chaos' you're about to suggest, just... no."
Aqua, who had been suspiciously quiet, suddenly emerged from the lower deck with an armful of salvaged wiring. Her hair was pulled back haphazardly with what appeared to be repurposed fiber mesh, and smudges of mechanical grease adorned her face like war paint.
"I think I can get the power running," she announced with uncharacteristic competence. "The base's power cells are completely drained, but I found a way to reroute energy from the thermal vent beneath us. It's just basic hydrothermody-whatsitz."
"You mean to tell us you jury-rigged the power relays?" Kazuma inferred, abruptly halting the fabricator for fear of the copper inputs being tasked for a redundant, recursive assignment.
"No, those are... still somewhere in the caldera," Aqua amended, pointedly averting her gaze. She could feel phantom sweat beading on her temples just thinking about the risks she took.
Kazuma and Megumin exchanged a long, searching look.
"What?" Aqua blinked, affronted. "I am a goddess. I assure you this other method is sound."
They kept staring, their skepticism palpable.
Feeling a bit flustered, Aqua rounded on them. "What, did you think I spent millennia just drinking and partying?"
"Yes," they replied in unison, the word hanging in the humid air.
One of the screens on the nearby wall flickered to life, Darkness' avatar appearing with a suspicious flush to her digital cheeks. "I've returned from my... exploratory mission," she purred, her digitized voice laden with barely contained excitement. "The SeaMoth sustained... sig-NIFICANT damage! From multiple collisions with underwater formations. The hull integrity was repeatedly compromised."
"You crashed it deliberately, didn't you?" Kazuma asked flatly, not even glancing over at the screen. Sighing, he gestured for Aqua to accompany him to the quieter end of the Multipurpose Room. It was clear something other than wrecked submersible was on his mind.
"The pressure at those depths was... intense," Darkness stated, clearly reliving the experience. "Every groan of the hull, every near-breach…pure ecstasy."
"Not now, Darkness," Aqua insisted, turning to follow Kaz, pointedly ignoring Darkness' ramblings.
There was little else said aloud for a spell, with eyes dully tracking over to the latest signs of activity outside their hab: a bustling school of bioluminescent fish scooting by the viewport.
Kazuma, arms crossed, nodded amicably at Aqua, or at least where she had been standing just a moment prior. He was forced to gawk unexpectedly as she reappeared directly behind him, clearing her throat as if that alone excused her sudden compulsion to vigorously wring water from his diving suit. "Leave off!" he shouted, backpedaling away from the surprisingly aggressive goddess.
"I should be telling you that!" Aqua, her face reddening, whirled to face the others, hands on her hips. "Crew, from this point on, everybody leaves wet diving gear at the airlock's designated stowage."
Megumin, tightening her hood about her bangs, glanced bemusedly at Darkness' avatar filling both the mounted overhead displays, and her own meticulously organized personal gear. She couldn't help but chuckle at how Darkness' avatar had shifted into the quaint, pixellated (>_>) emoticon.
Relenting, Aqua sighed and withdrew further argument, stepping away from Kazuma. Her foot brushed against something, and as she averted her gaze she was only mildly surprised that it was his discarded dive suit. "Really?"
Half-naked and with a sheepish look back at her, Kazuma retreated quietly for the vending machines.
That jerk really wasn't scoring any points with her, she figured, stooping to retrieve the suit. Wordlessly, with a bit of a pout, she made for the washing station to hang it up in the meager queue of spare suits. Those would have to wait, as plenty else was still running through the unit's sluggish yet stubborn cleaning cycles.
Well, working appliances surely had to count for something. Assuredly, Aqua figured, this prefabricated hideout was beginning to show signs of slow progress. Another viewport was patched, thanks to Kazuma's latest excursions. Even the salvaged fabricator from a base before was dutifully churning out interior refinements.
But, the air still hung thick with humidity, and the constant creaks of the ocean's pressure were a grim reminder of the long road ahead as far as base-building was concerned.
A pair of footsteps entered into earshot, drawing her from her reverie.
Aqua scowled. Their limited resources meant it was too easy to bump into Kazuma while she was keen on avoiding him. "Spare me the apologies. We really need to up the timetable here," she said at length, still not looking his way.
"Ah?"
"Hmm? I--" Aqua, an incredulous look flitting across her features, turned. She seemed eager to head off further confrontations.
Kazuma, smiling faintly, raised a hand to infer ahead of her: "We got off on the wrong foot. Now, as you may recall...?"
"Why, yes. You were needing me for something? Well, I'm all ears. Spit it out."
Kazuma, narrowing his eyes as he tried to dissect her tone, at last broke forth with: "So we have a base without properly installed reinforcements, not to mention the suspiciously janky hydrothermody-whatsitz power supply from a certain resident goddess with suspiciously convenient technical skills..."
"I have my moments."
"Hmm. Well, that, on top of our navigator being a bit off her rocker."
"That's just how she is sometimes."
"Who in their right mind--?"
"Digitized mind, remember?"
"Sure. But, ah speak of the Devil." Kazuma turned, whipping out his communicator. "Darkness. What exactly are you up to?"
Aqua sighed, turning to regard the visual disturbance outside their section of the hab.
But, it wasn't Darkness.
Sinusoidally, a silhouette of uncomfortable proportions passed over the habitat's observation window just then—until part of it at last caught upon the base floodlights. Massive, unmistakably predatory.
"Reaper Leviathan," Megumin whispered, eyes widening with a mixture of terror and inappropriate enthusiasm. Sticking out a thumb and forefinger, she gauged its proximity. "Darkness?"
"I see it, setting time-delayed gas torpedoes."
"Outstanding."
Kaz and Aqua both turned as Megumin, unexpectedly all business, took a seat within the SeaMoth.
Aqua, rolling up a sleeve, seemed of a mind to demand release of the Power Cells. But, she hesitated.
Megumin beamed, pressing her face against the SeaMoth's forward glass, causing it to fog up a bit. She released the SeaMoth in time for the Reaper to begin its next pass, its own twin beams sizing up the sea creature's forward pincers which were waggling with renewed gusto, as if resonating with the SeaMoth pair's own eagerness for a bit of fisticuffs.
"Leave them to their fun," Kazuma suggested, limping over a bit bedraggled. His dive suit was in the wash, so he was trying out the much heavier, lead-lined radiation-proofed suit to no avail.
Just then, their habitat's newly restored lights flickered ominously as the whole structure shook.
Figuring it was Darkness and Megumin's latest quarry bumping against the outer hull, Aqua reacted swiftly, grabbing a wrench and listening intently for signs of fresh leaks. Instead, her eyes hit upon their precious equipment, that which had been painstakingly scrounged from the previous, ill-fated build and left out on the upper exposed portions to dry for a while. There it now went, slipping free and twirling serenely into the abyss below.
This set her off. Gritting her teeth, Aqua dropped the wrench, quivering. "I'm supposed to be purifying water and performing party tricks, not staring down things that seem content with popping our base rebuilds open like a can opener!"
"Actually," Darkness interjected through the speakers, her voice dropping to a husky whisper as Megumin began improving her aim for another go, "that was probably us. Though, I should call to your attention what else is approaching from the thermal vent. It's... not a natural life form."
The entire habitat shuddered as another concussive wave rolled through the water, rattling loose storage containers and sending a cascade of tools clattering to the floor. Kazuma pressed his face against the viewport, squinting through the turbulent waters as flashes of light illuminated the darkness in rhythmic pulses.
"Darkness, you are confident in your aim?"
"When have I ever failed you?" she challenged dramatically.
Shaking his head, he motioned to Aqua. "You better come take a look at this."
Aqua, squinting, sized up the patch of ocean under scrutiny. Her eyes quickly began tracking the trajectory of what could only be torpedoes but certainly not standard-issue or civilian grade. "Hmm. Those definitely aren't ours."
Just then, the massive silhouette of the Reaper Leviathan shifted course, its bulk thrashing against the nearby outcrop of a sediment bank that seemed to envelope this patch of kelp forest in their midst. Was it twisting in pain or rage? It seemed, at the very least, to be abandoning the hunt.
Then, behind it, emerging from deeper waters, a masterwork of human engineering prowled and slowed to a halt, large beams of light and the ping of a high-powered sensor sweep. It was a Cyclops-class submarine, easily better equipped than their habitat. Yet, its reinforced hull was adorned with unfamiliar insignia.
"Are those... rescue teams from the Aurora?" Aqua asked, hope coloring her voice as she crowded beside Kazuma at the window.
Another torpedo burst illuminated the submarine's hull, revealing emblems Kazuma had hoped never to see again—stylized golden coins against a blood-red background, the unmistakable sigil of Mammon's faction.
"Not rescue," he said grimly. "Mammon's people."
The habitat's power flickered, emergency systems cycling as electromagnetic interference from the torpedo detonations disrupted their electronics. For a moment, they were plunged into darkness, the only illumination coming from the battle unfolding beyond their viewport.
Then, with a discordant squeal, the communication array crackled to life. A martial melody blared through the speakers, accompanied by a voice speaking in a language that made Megumin's eyes widen in recognition.
"What's it saying?" Kazuma demanded over Darkness' snickering (apparently she knew, being digitized).
Megumin: "Eh, it's really not all that special."
Aqua, rising intently: "Let's hear it!"
Megumin complied, cranking down the radio's volume as she recited from memory:
"How frowned upon like glaciers
Yet nobly proceed
to fill up the coffers--
in the name of Mammon's greed!
Our flotilla is like trophies
caught from wreck and shore alike,
yet none can contend
with the Vanguard's righteous strike!"
She trailed off with a shrug. "It goes on like that for another twelve verses. Typical propagandistic drivel about pillaging in the name of--"
"I catch the drift," Aqua surmised, shaking her head in dismay.
"You understand their language?" Kazuma asked, for the moment distracted.
Megumin's crimson eyes flickered with something like embarrassment. "The Crimson Demon Clan has ancient ties to many realms. We're required to study the linguistic patterns of potential allies and enemies alike."
"I could have used an ambassador at--" Darkness begat.
"Not now, Darkness," Aqua demanded, before stepping clear of the prying eyes of the visiting Cyclops to confer with Megumin quietly. "You never mentioned this before."
"Oh, I'm sure I had. But," Megumin paused, considering. "More importantly, mayhaps, I don't know how much of a bargaining chip we might possess."
"So, they mean to come aboard?"
"Why else?" Megumin aired with a shrug.
The habitat's external floodlights activated automatically as motion sensors detected approaching objects. Three sleek Seamoths circled their structure like sharks assessing prey, their hulls bearing the same Mammon insignia as the larger vessel. Behind them, the massive Cyclops hovered at a distance, its forward lights cutting through the murky water with clinical precision.
Soon enough, the communication array crackled afresh, the anthem fading as a more immediate transmission cut through. A voice, liquid and eerily familiar, rippled from the speakers.
"Attention, survivors of the Aurora. This is Captain Sylvia of the Mammon Vanguard vessel
Calamitas. Your presence has been noted, cataloged, and deemed potentially useful. Stand by for visitation."
Darkness' digital avatar materialized on the nearest screen, her expression unusually serious. "Aqua, this is the first I've seen anyone single-handedly eliminate a Reaper-class threat."
"Be that as it may, let us await their delegation, shall we?" Kaz ventured, straightening his lounge wear.
"Visitation," Megumin echoed theatrically. "That's a pleasant euphemism for taking us all hostage."
Aqua had retreated to the fabricator, her hands moving with nervous energy as she assembled what appeared to be a makeshift weapon from salvaged parts. "Last time we encountered Mammon's people, you might recall, they tried to press us into the service. I'm not becoming anyone's conscript."
"Technically," Darkness corrected blandly, "they were as much at a loss in understanding how our abilities function in this reality's physical framework. It seemed more scrounging up living specimens. Nothing like earnest, spur of the moment research to awaken the senses."
"Not helping," Kazuma growled, reaching for his diving knife—a pathetically inadequate defense against whatever firepower the approaching swath of SeaMoths readily commanded.
"How much time do we have?" Aqua inquired.
"They're establishing a perimeter," Darkness observed, her voice carrying an undercurrent of excitement that Kazuma chose to ignore. "Standard containment protocol. They don't know if we're hostile."
"We're about to be," Kazuma muttered, tightening his grip on the knife.
The water directly in front of their main viewport rippled with distortion—not the natural movement of currents, but something more deliberate. A figure materialized from the turbulence, humanoid but wrong in subtle, unsettling ways. Webbed hands. Gill-like structures pulsing along an elongated neck. Eyes adapted for the deep, reflective and cold.
But the face—the face was unmistakable, despite its alterations.
"Sylvia," Megumin whispered, unconsciously stepping back from the viewport.
The transformed figure smiled, revealing teeth that had been modified for an omnivorous marine diet. In her arms was a cylindrical device that pulsed with familiar blue light—a habitat builder, the very technology they had been scavenging parts to repair.
With deliberate slowness, Sylvia gestured toward their airlock, then to the Reaper's retreating form, before pointing significantly to the device in her hands.
"I think," Kazuma said slowly, his mind racing through possibilities, none of them promising, "she wants to talk."
The habitat's external communication system activated, projecting Sylvia's voice through the water and into their sanctuary:
"Open your airlock, darlings. The depths are no place for old enemies to maintain their grudges. Not when there are greater threats lurking below."
As if summoned by her words, a massive shadow passed beneath the Cyclops, so vast that it momentarily eclipsed the submarine's running lights. Something ancient and patient moved in the abyss below—something that made even the Reaper Leviathan seem like a minor inconvenience.
Kazuma exchanged glances with his companions, reading in their expressions the same reluctant conclusion he had reached. They needed allies in this alien ocean. Even if those allies came with agendas of their own. "Darkness," he sighed, regretting his decision, "prepare the airlock for our... guest. I guess."
