Morning light bled through the gaps in the black velvet curtains of Hespera's bedroom, painting thin gold lines across the obsidian walls. She stretched beneath the black silk sheets—a full-body feline arch that made her silver-streaked hair fan across the pillows in chaotic swirls—before reality hit with the force of a physical blow: today was the day. Her arm flopped over her eyes with theatrical emphasis as she groaned at the ceiling.
"Ugh. The Underworld trip is today, isn't it?"
The question bounced off the walls of the vast bedroom, receiving no answer but her own echo. The spatial ring on her middle finger—the delicate woven band of blackened silver laced with veins of amethyst and amber—pulsed in response, the metal warming against her skin as it vibrated with a slow, steady rhythm.
Then Noctis's voice filtered directly into her mind, flat and precise: "Mistress. Awake?"
Hespera delivered a slow, exaggerated sigh that made the room's temperature drop two degrees. "Noctis, darling," she drawled, throwing her legs over the edge of the bed with enough force to send the silk sheets sliding to the floor. "If you're going to be in my head this early, at least make me breakfast."
There was a pause—the particular silence that meant Noctis was considering the request with absolute seriousness despite its obvious impossibility. "..." she began, then fell quiet again before responding with perfect honesty: "...Noctis lacks limbs to do so."
A snort escaped Hespera's lips as she shoved herself upright, bare feet sinking into the plush carpet that covered the obsidian floor. "Excuses, excuses~" she muttered, not bothering to hide her amusement.
The room stretched around her in perfect gothic elegance—black silk sheets tangled at the foot of a massive bed on its raised dais, obsidian walls reflecting the morning light in strange, impossible angles, weapons of every description mounted on the far wall in a careful display of Hespera's many hobbies. The Chaos Core spun lazily at the center of the room—a perfect sphere of chaotic energy humming with quiet amusement at her complaints—while the massive vanity in the corner caught the light and fractured it into patterns too complex to track.
Hespera padded toward the bathroom, waving one hand at the Chaos Core as she passed. "You're not helping either," she informed it, the orb pulsing once in acknowledgment before returning to its lazy spin.
The bathroom door swung open at her approach, responding to her will with the particular eagerness of an object that recognized its mistress. The space beyond was all obsidian and silver—the walls covered in a black mosaic that caught the light in impossible ways, the fixtures gleaming with ancient polish. Orchids bloomed from tiny black-violet plants growing along the walls, their scent filling the air with subtle sweetness.
Steam began to curl around her feet as Hespera approached the mirror—a massive slab of frosted glass framed in silver and obsidian. She leaned forward, chin propped on one hand, and said clearly:
"System, open."
The black-and-silver interface materialized mid-air, hovering at eye level with a sound like wind chimes in a distant storm. Arcane code scrolled across its surface in elegant golden script, the symbols rearranging themselves with each passing second. Three notifications glowed at the edge of her vision, pulsing with particular urgency.
Hespera tapped the first one with a lazy finger, watching it expand with visible interest.
[YOU HAVE EARNED THE TITLE: C A T T A M E R]
[Through your expert manipulation of feline physiology and psychology, you have gained the ability to influence the behavior of all cat-type supernatural beings. Your touch carries enhanced soothing properties for the species, and your commands will be followed with increased obedience.]
Hespera's lips curved into a slow smirk, the memory of Koneko—all prickly suspicion and carefully maintained distance—melting into a purring puddle with a single scratch behind the ears replaying in vivid detail. "Well, that's going to be fun to use," she murmured, already imagining a dozen scenarios where this particular ability would prove useful. Kuroka alone would be worth the price of admission—a millennia-old nekomata with nine tails and centuries of casual chaos reduced to putty with a single targeted scratch.
She tapped the second notification, watching it expand with careful attention.
[ITEM DROP: C H A O S P I E C E S]
[Fifteen non-standard Evil Pieces created by Chaos themselves. Unlike traditional Evil Pieces, which can only convert supernatural beings or humans of exceptional talent, Chaos Pieces can transform ANY willing target into a Devil peerage member. The resulting transformation is directly influenced by the target's original supernatural nature, creating a hybrid form that transcends conventional categories. Each piece carries a specific function determined by the user's intention during conversion.]
Hespera's smile stretched wider, canines gleaming in the steam-clouded mirror. "Oh, now this..." she breathed, eyes tracking the text with hungry focus. "...this is interesting."
The pieces hovered at the edge of the screen—fifteen jagged shards of what looked like solidified shadow, pulsing with chaotic energy. They were completely unlike the traditional Evil Pieces that devils like Rias used to create their peerages—where those were perfect spheres with carved symbols representing different ranks, the Chaos Pieces were all sharp angles and jagged edges, their surfaces inlaid with patterns too complex to track with the naked eye.
Hespera's smirk took on a particular edge of satisfaction. "Mom's spoiling me again," she murmured, the statement carrying the fond exasperation of someone who had received exactly what they wanted but still felt the need to acknowledge the effort.
She tapped the final notification, her eyes gleaming as the text scrolled into view.
[SYSTEM SKILL UNLOCKED: T R A C K E R]
[You can now sense and follow the "essence trail" of any being you've personally encountered. Even beings who have used divine-level concealment abilities will leave traces in the fabric of reality that only you can perceive. Your eyes will instinctively lock onto their location when in proximity, regardless of conventional hiding methods. The skill's effectiveness increases with your personal familiarity with the target.]
Her lips curved into a slow, dangerous smile. "Playing cat and mouse should be quite entertaining in the future," she hummed, already imagining the particular expressions on certain faces when they realized their hiding places weren't actually hidden.
She swiped the interface closed with one quick, decisive gesture—the screen folding in on itself with a sound like distant thunder—and stepped into the shower. The water hit her skin at just the perfect temperature—scalding hot, just shy of painful, the kind of heat that would have blistered a normal human's flesh but that Hespera's chaos-touched body welcomed with pleasure. She rolled her shoulders under the cascade, watching as steam billowed around her in perfect white clouds.
Her mind turned over each new ability with methodical precision, weighing potential applications against the particular challenges of her upcoming trip to the Underworld. The Gremory family would be watching her with careful attention—they had invited a complete unknown into their territory, after all. She'd need to be impressive enough to earn their respect but not so intimidating that they decided she was more trouble than she was worth. The balance would be delicate, requiring just the right mix of power and control.
She tipped her head back, letting the water sluice through her silver-streaked hair in rivulets that caught the bathroom light. Her relationship with the Gremorys would be vital to her plans—they were one of the four great devil families, after all, with connections that ran deep throughout the supernatural world. If she wanted to reshape the story that had been written, to shift the flow of events away from the carefully balanced plot that had been constructed around Issei's existence, she would need allies. Powerful ones. Ones who already had reason to dislike the narrative's original arc.
And Rias Gremory—trapped in an engagement to a man she despised, surrounded by subordinates who loved her but couldn't challenge the system that bound her—had every reason to want things to change.
Hespera chuckled, the sound bouncing off the bathroom walls. "It's going to be a delightful trip," she informed the empty room, her voice lilting with genuine pleasure.
Steam billowed around her as she stepped fully under the spray, silver-to-violet hair plastering to her skin with each movement. Her reflection in the shower glass was distorted by condensation—a figure of chaotic potential rendered in elegant, dangerous lines. She grinned at it, canines catching the light, and began to sing—a cheerful, deliberate tune that made the steam swirl in impossible patterns around her.
Somewhere in Kuoh, a portal was opening to the Underworld. And somewhere in the architecture of fate, pieces were falling into place with perfect, terrible precision.
Hespera stepped out of the shower wrapped in a cloud of steam, water beading on her olive skin as she reached for a plush black towel. She paused, hand extended toward the rack, then grinned—a sharp, predatory expression that transformed her face from merely beautiful to something that existed on the knife's edge between lovely and dangerous. With a casual flick of her wrist, she summoned a thread of [Nihility]—a thin, controlled burst of mana that rippled through the air like a heat wave.
The spell hit her with the force of a physical blow—not painful but intense, a surge of power that made every nerve ending fire at once. Steam billowed around her in a perfect sphere, water evaporating from her skin with a hiss like a snake's warning. Her hair lifted with the sudden energy, strands of silver, violet, indigo, and green-blue floating around her head in a chaotic halo before settling back into place with perfect, impossible weightlessness.
She stretched—a full-body arch that made her vertebrae crack pleasantly—and strolled toward her walk-in closet with unhurried grace. Her reflection in the shower's glass door was distorted by condensation—a figure of chaotic potential rendered in elegant, dangerous lines. She winked at it, the gesture carrying the particular weight of someone who knew exactly how much power they wielded.
The walk-in closet stretched three times the size of a normal room—another little convenience Ophis had arranged when building the mansion. Each wall was lined with clothing of every conceivable style and era, from ancient armor to modern haute couture, arranged in perfect rows by color and occasion. A plush velvet bench sat in the center of the room, positioned exactly for Hespera to examine herself from every angle in the full-length mirrors that lined the far wall.
Hespera paused at the threshold, one finger trailing along the polished ebony of her vanity table. She had made the trip to hell's aristocracy a thousand times in the past—in worlds that existed only in the potential space of "what if," in dimensions that had been created and destroyed by entities beyond mortal comprehension. But this was the first time she would be going as herself—not as an observer, not as a catalyst for someone else's story, but as a player in her own right.
She tilted her head, silver-streaked hair sliding across her shoulder with the movement, and posed the question aloud to no one in particular:
"Now... what to wear to my grand debut in Hell's aristocracy~?"
She flicked her wrist with casual precision, and seven outfits materialized in the air before her—hovering in perfect suspended animation, each piece frozen at exactly the right angle for inspection. The first was all structured lines and severe cuts—a formal dress suit in gleaming black, the shoulders sharp enough to cut, the entire ensemble radiating the particular authority that came with old money and older power.
Hespera wrinkled her nose. "Too formal," she declared, waving her hand dismissively. The outfit collapsed in on itself with a sound like distant thunder, disappearing into nothing.
The second outfit—a sleek cocktail dress in the exact shade of her amethyst eye, edged with black lace that seemed to move of its own accord—stayed in place for exactly two seconds before she wrinkled her nose again. "Too stiff," she decided, and it too vanished with a flick of her wrist.
The third—a flowing black and crimson ensemble that seemed to be made of shadow given physical form—lasted even less time. "Too boring," Hespera dismissed, already turning her attention to the fourth option.
And so it went, outfit after outfit rejected for flaws only Hespera could see—too dramatic, too understated, too reminiscent of a specific historical period she'd decided wasn't in fashion this century. Her expression grew more amused with each dismissal, her commentary more theatrical, until only one outfit remained suspended in the air—a final option that had made it through her increasingly arbitrary cuts.
"Ahhh," she breathed, eyes lighting with sudden interest. "There we go~"
She snapped her fingers—once, twice—and the outfit assembled itself around her in a blur of movement too fast to track. The sensation was like being briefly dipped in liquid shadow—cool, smooth, with a pressure that faded the moment it settled into place. When the movement stopped, Hespera stood at the center of a swirl of dissipating darkness, her new ensemble perfectly arranged on her frame.
She examined the effect in the mirror, taking in each piece with careful attention. The sleek high-collared black crop top hugged her toned frame like a second skin, the fabric catching the light in ways that made it seem simultaneously solid and immaterial. It bared a perfect strip of olive skin at her waist—not enough to seem provocative but enough to hint at the strength beneath. A silver cross pin gleamed at her collarbone, a small ironic joke given her divine-infernal nature, the metal catching the light with each breath she took.
The oversized black jacket draped off her shoulders like a cloak—not quite formal enough to be respectable but not casual enough to be comfortable. It hung with perfect precision, the heavy fabric moving with her gestures in a way that emphasized their deliberate nature. It made her shoulders appear broader, her stance more imposing—a silhouette designed to command attention without demanding it outright.
Crisp high-waisted white pants cinched her waist with a black belt that matched the jacket's exact shade—the kind of detail that most people wouldn't notice but that would catch the eye of anyone who had been trained to look for the signs of old money. The pants flowed into polished black combat boots that rose to just below her knee, the leather gleaming with subtle menace. A single dangling strap at the hip—the only deliberately asymmetrical element in an otherwise perfectly balanced ensemble—completed the look, drawing the eye to the precise center of her frame.
Hespera turned before the mirror—a slow, complete rotation that let her examine the outfit from every angle. The gothic mirror—a massive slab of silver-backed glass framed in blackwood carved with symbols too complex to track—caught her reflection and held it with perfect clarity. Behind her, the manor's shifting wall-patterns rippled faintly—galaxies swirling into nebulae, storms of color giving way to perfect darkness, reality itself seeming to bend around her presence.
She ran one hand over the jacket's fabric, watching as her reflection did the same. The balance was exactly right—elegant enough to command respect, defiant enough to establish that she answered to no one but herself. The kind of outfit that would let her walk into the Gremory estate with the absolute certainty that she belonged exactly where she was, doing exactly what she was doing.
"Business but casual, definitely was the best choice," she murmured, turning one last time to check the back view—the way the jacket fell in a perfect line from her shoulders to the small of her back, the slight ripple in the fabric that caught the light when she moved.
Satisfied, she turned from the mirror with a smirk already forming—a small, dangerous curve of lips that promised trouble for anyone who crossed her path. "Time to see if mom is ready," she announced to the empty room, her voice lilting with theatrical anticipation.
She strode from the bedroom with unhurried confidence—the particular gait of someone who had already decided the day belonged to them, who moved with the absolute certainty that everything would bend to accommodate their will. Her boots clicked softly against the obsidian floor, the sound echoing through the vast chamber with perfect precision. The spatial ring caught the candlelight as she moved, the embedded amethyst and amber gleaming with inner fire as if responding to the potential unfolding before them.
She paused at the threshold, glancing back at the room one last time—taking in the perfect chaos of her creation, the weapons mounted on the wall, the Chaos Core still spinning at the room's center, the bed with its tangle of black silk sheets. Then she grinned—a quick, dangerous flash of teeth—and stepped into the hallway beyond.
The game was about to begin in earnest.
☆=
The Gremory estate stretched like a sleeping beast across the landscape of the Underworld, its spires cutting into the eternal twilight like teeth. The great dining hall—a cavernous space at the mansion's heart—was quiet with the particular charged stillness of a family in the middle of something serious. A table long enough to seat a small army dominated the center of the room, its polished mahogany surface laden with untouched extravagant dishes that steamed with infernal heat. Crystal goblets gleamed at perfect intervals, filled with wine the exact shade of fresh blood.
Soaring ceilings rose above them, arching into perfect darkness that seemed to stretch beyond the physical boundaries of the room. Chandeliers of black crystal hung from chains of pure darkness, each one carved with the intricate sigil of the Gremory clan—the symbol of the original devil's power burning with crimson light at its center. Deep crimson and gold furnishings lined the walls—silken draperies that shifted slightly despite the absence of wind, chairs carved from the bones of ancient beasts, tables inlaid with jewels that caught the light and fractured it into patterns too complex to track.
The faint hum of infernal magic wove through the stone walls—a constant, subtle vibration that made the air feel slightly too thick to breathe, the kind of background energy that would have been overwhelming to anyone not born of devil blood. Portraits of long-dead Gremory ancestors watched from the walls, their eyes seeming to follow each person as they moved, their expressions caught in the particular combination of pride and judgment that only immortals could properly master.
Lord Zeoticus sat at the head of the table, his crimson gaze contemplative as he listened to his daughter's report. He cut an imposing figure even in repose—back straight as a blade, shoulders broad beneath his formal black suit, the centuries of his existence etched into the careful lines of his face. He had not touched his food, had not moved from his position when Rias had entered the room with her news. His silence carried more weight than most people's speeches—the particular stillness of someone who had existed long enough to understand that words were generally unnecessary.
Lady Venelana sat beside him, refined and sharp-eyed, her back not quite touching her chair. She wore a simple white dress that somehow managed to convey both elegance and absolute authority, her flaxen hair, falling across her shoulders in a perfect wave. She held her wine glass between two fingers, the liquid inside barely disturbed by her movements, her attention fixed on Rias with careful precision.
Rias had barely touched her food—a single bite of roasted meat pushed to the side of her plate, her fork balanced across the rim rather than laid properly beside it. Her fingers tapped against the polished wood of the table—a rapid, nervous rhythm that she couldn't seem to stop despite her visible efforts to appear composed. She wore the particular expression of someone who had delivered difficult news and was now waiting for the response—chin lifted, eyes direct, but tension visible in the set of her shoulders.
Sirzechs sat further down the table, his usual playful energy dialed back to something more attentive—the particular stillness of a predator who had spotted something interesting. His posture remained casual—one arm draped across the back of his chair, legs crossed at the ankle—but his eyes had taken on that dangerous gleam that always preceded trouble. Grayfia stood at his side, her silver hair falling across her shoulders in a perfect sheet, her expression giving nothing away despite the careful attention visible in her gaze.
"—and that's everything I know," Rias finished, the words emerging with the careful precision of someone who had practiced them several times in advance. "She appeared out of nowhere, carries herself like nothing in the world can touch her, offered to help in the Rating Game against Riser, and..." She paused, her fingers stilling against the wood. "She claims to share DNA with the Phenex family."
The table went perfectly still—not just quiet but still, as if the air itself had frozen at the statement. Lord Zeoticus's brows lifted slightly—the closest thing to surprise his controlled features ever showed. Lady Venelana's fingers tightened imperceptibly around her wine glass, the liquid inside remaining perfectly still despite the movement.
"She what?" Sirzechs asked, his voice carrying that particular note of someone who had heard perfectly well but wanted confirmation.
Rias met his gaze without flinching. "She says she shares DNA with the Phenex family," she repeated, each word precisely formed. "She didn't clarify how, exactly. Just that it was 'technically accurate enough' for our purposes."
Venelana set her wine glass down with careful precision, the crystal making no sound against the table. "And yet," she said, her voice carrying the particular weight of someone stating an obvious fact, "you invited her to the Underworld."
It wasn't quite a question—more an observation that carried the weight of expectation. Rias sighed, her chin dropping to her palm with a resignation that would have been comical if the stakes weren't so high.
"Yes," she admitted, the word emerging with the carefulness of someone forcing themselves to remain calm. "I'd be a fool not to hear her out. The Phenex family's connections run deep, and Riser's healing abilities make him nearly impossible to defeat in combat." Her fingers curled into a fist against the table. "If she can help us—if she really does have some connection to the Phenex line that we can use—"
"She could be exactly what you need," Grayfia finished, her voice steady and matter-of-fact.
The beat of silence that followed the Phenex DNA revelation broke when Sirzechs laughed—a deep, genuinely delighted sound that seemed to physically lighten the air in the room. He leaned forward, chin propped on his folded hands, eyes gleaming with sudden, genuine interest.
"How fascinating," he said, each word carrying the particular weight of someone who had just made a significant discovery. "A wildcard who isn't bound to any of the major factions..." He paused, his grin widening to show a perfect row of white teeth. "...yet."
Rias frowned, her blue eyes fixing on her brother with careful attention. "Brother, this isn't a joke," she said, the words emerging sharper than she'd intended. "There's something off about her. The way she moves, the things she can do—it's not like anything I've seen before."
Sirzechs's expression shifted—not to seriousness but to a particular kind of pleased calculation that made Rias's stomach drop. "Oh, I don't doubt that," he said, his voice taking on that particular edge that always preceded trouble. "In fact, I'd be disappointed if she were ordinary." He turned to Venelana, his expression openly curious. "What do you think, Mother?"
Venelana considered for a long moment, her gaze fixed on some middle distance beyond the table. Then she turned to Rias, her expression softening almost imperceptibly. "She has piqued my interest," she stated, the words carrying the weight of absolute certainty. "The fact that you feel uncertain about her suggests she's someone worth watching."
Lord Zeoticus had remained silent throughout the exchange—a particular kind of quiet that made even Sirzechs straighten slightly in his chair. When he finally spoke, each word emerged with careful precision, the kind of measured judgment that had shaped devil politics for centuries.
"We will observe," he stated, the words neither question nor suggestion but absolute decree. "But I expect a proper introduction when she arrives."
The statement hung in the air—not quite a challenge but definitely not backing down. Sirzechs grinned, his playful energy fully restored, mischief dancing behind his eyes like living things.
"Well," he said, raising his wine glass in a toast that encompassed the entire table, "it sounds like this Hespera will make the Underworld far more entertaining."
Rias did not share his enthusiasm. She exhaled slowly, the certainty settling over her like a physical weight—the perfect, absolute knowledge that this was going to cause a great deal of trouble.
And that she had invited it herself.
