The Sullivan mansion stood as it had stood for centuries—imposing, elegant, slightly ridiculous.
It was the home of a demon who had accumulated too much over too many years, who had never learned the art of subtlety, who filled his space with the evidence of his long life and longer loneliness.
Towers that served no purpose jutted from the roofline. Gardens that required an army of magical constructs to maintain sprawled across grounds that could have housed a small city. Rooms led to rooms led to rooms, many containing treasures that Sullivan had forgotten he owned, others containing memories he visited only in the darkest hours.
It was, in short, perfect for a child.
Or it would be, Sullivan thought, as he cradled the egg-chamber against his chest, once there was a child to fill it.
"Opera," he announced, sweeping through the main hall with the energy of a demon half his age, "we must prepare. The nursery—does it have sufficient warmth? Nature spirits require specific temperatures during incubation, I recall reading somewhere, or perhaps I am thinking of reptiles, but regardless—warmth! And humidity! And—"
"Sullivan-sama." Opera's voice was dry, familiar, the tone of a servant who had managed their master's excesses for centuries and would manage them for centuries more. "The nursery has been prepared. Temperature regulated to match the Heart Tree's grove. Humidity maintained at optimal levels for nature-magic incubation. I have also," they added, with the slightest pause, "removed the decorative weapon collection from the walls. And the taxidermy. And the skeleton that was apparently 'educational.'"
Sullivan deflated slightly, his enthusiasm checked but not diminished. "Ah. Yes. Good. Very good. Though the skeleton was quite rare—a two-headed wyvern from the Northern Wastes, you know, killed by my own—"
"It was frightening, Sullivan-sama."
"...Yes. Quite right. Frightening. Not appropriate for a nursery." Sullivan looked down at the egg-chamber, still pulsing with gentle light against his chest, and his expression softened into something that would have shocked the Thirteen Crowns who knew him only as the powerful, the eccentric, the occasionally terrifying. "Nothing frightening for you, little one. Only warmth. Only safety. Only..."
He trailed off, because the words were too large, the feelings too raw. He had not expected this. Had expected duty, responsibility, the satisfaction of keeping a promise. He had not expected the terror of hoping, the vulnerability of caring for something that could not yet care back.
Opera observed their master's silence with the patience of centuries. Then, gently: "Where would you like the chamber placed, Sullivan-sama?"
"My study," he decided, the words emerging without thought, driven by instinct he had not known he possessed. "Beside my desk. Where I can see it. Where I can speak to it. Where—" He caught himself, aware suddenly of how he must sound, this ancient demon, one of the Three Greats, fussing over an egg like a hatchling mother bird.
But Opera merely nodded, as if this were reasonable, as if this were expected. "Very good, Sullivan-sama. I shall bring tea. And perhaps..." a pause, "you might tell him of his mother?"
Sullivan's eyes—usually hidden behind pince-nez, usually crinkled with forced cheer—met Opera's, and there was understanding there. Shared grief, though Opera had not known Silva, had only witnessed her ending.
Shared hope, though hope was something Sullivan had avoided for years, since Delkira, since the emptiness that had driven him to search for meaning in service rather than family.
"Yes," he whispered. "I will tell him of Silva."
---
Time in the demon world was flexible, measured not merely in hours but in events, in growth, in the accumulation of meaning. But for Sullivan, these days were marked by waiting, by watching, by the slow revelation of an unexpected self.
He had never been patient. Not truly. His perfectionism—the trait that had made him legendary as an administrator, infamous as a principal, cursed (he believed) by the last Demon King—demanded results, completion, the satisfaction of a thing done and done well. He could not tolerate the unfinished, the imperfect, the potential rather than the realized.
And yet.
And yet he sat, day after day, beside an egg that did not hatch, that showed no signs of hatching, that pulsed with life and promise and refused to deliver either into his waiting hands.
He talked to it.
At first, the silence of the study had seemed to demand filling, and Sullivan had filled it with the comfortable nonsense he used to distract from deeper matters. He spoke of the weather—always interesting in the demon world, where weather was often sentient and occasionally hostile. He spoke of his plans for the school, the politics of the Thirteen Crowns, the annoying habits of his colleagues.
But gradually, the nonsense had deepened, shaped by the presence of the listening—or perhaps not-listening, but familiarizing.
"Your mother," he said, on the third day, "was gentle. I want you to understand that, Cirrus. Whatever you learn of her later, whatever you discover of her ending—she was gentle. She served her forest for three hundred years, never asking for more than the peace of growing things."
The egg pulsed, and Sullivan chose to read acknowledgment in the rhythm.
"I am... not gentle," he confessed, the words tasting of strange honesty. "I am powerful, and I am busy, and I am accustomed to having my way. Your mother would scold me for this, I imagine. She often scolded me, when I brought visitors to her woods. 'Sully,' she would say, 'you rush too much. You miss the growing by watching for the grown.'"
He laughed, a sound that startled him, rich and real and rare.
"She called me Sully. Imagine! No one has called me that in..." he counted, gave up, "in centuries. Not since Delkira."
The name hung in the air, heavy with history, with grief not yet processed.
"Delkira was..." Sullivan paused, searching for words that would not overwhelm, that would not frighten the small life he cradled. "He was the Demon King. The last true Demon King. And he was my... my friend. My responsibility. I served him, you see, as I hope you will allow me to serve you. Not as king, but as... as family."
The egg pulsed, and this time Sullivan felt something different—a resonance, a harmonic that matched his own mana signature, that suggested connection, recognition, trust.
"Yes," he whispered, "family. That is what we shall be, Cirrus. What we are, whether you know it yet or not. I am your grandfather now. And I will earn that title, I promise you."
---
By the seventh day, Sullivan had established a routine.
Mornings, he spoke of practical matters—the Netherworld, its geography, its politics, the delicate balance that kept civilization from collapsing into the chaos that was every demon's birthright.
"There are thirteen of us," he explained, "**who rule in the King's absence. The Thirteen Crowns. I am one—ranked Tet, the ninth level, though I refuse to advance to Yodh, the tenth. Do you know why?"
The egg listened, or seemed to."Because I am a perfectionist, Cirrus. Because I believe that a thing must be done right or not done at all. And the Demon King... the Demon King must be many things that I am not. Must be greedy, for power, for attention, for the love of his people. Must be selfish, in the way that leaders must be selfish—taking responsibility as others take pleasure."
He paused, remembering Delkira's laughter, his restlessness, his refusal to sit still while others suffered.
"Delkira cursed me, I think. Not formally—he was not spiteful—but with his absence, his disappearance. He knew I would search for him forever, and he knew I would never find him, because I am too perfect, too careful, too afraid of failure to risk the wild places where answers might hide."
The bitterness in his voice surprised him. He had not spoken of this to anyone. Not to Opera, who knew anyway. Not to the colleagues who would misunderstand.
"But you," he continued, forcing cheer, "you will be different, Cirrus. You will have my perfectionism—I see it already, in the care with which you develop, the patience of your pulsing—but you will also have your mother's gentleness. Her connection to living things. You will be better than I am. Stronger, Wiser.
Afternoons, he spoke of Opera.
"They have served me since they were young," he recounted, "since before they knew how to serve tea properly. Can you imagine? Opera, fumbling with a teapot, spilling expensive leaves everywhere, their face—" he gestured vaguely, "their expression, whatever it was at the time—absolutely mortified."
He chuckled, remembering.
"I should have scolded them. A proper master would have. But I saw potential in their embarrassment, their determination to improve. And I was right—they are the finest familiar any demon could ask for. Though they will deny it if you ask, they are also fiercely loyal, fiercely protective. They will guard you as they guard me. As they guarded your mother, in her last moments."
Evenings, he spoke of darker things, because sheltering was not protection, and ignorance was dangerous in a world that tested its young.
"There are ranks, Cirrus. Ten of them, from Aleph to Yodh. You will start at the bottom, as all must, and you will climb through merit, through cunning, through the demonstration of your power. This is the demon way. We value strength, ambition, the hunger to become more."
He touched the egg's surface, feeling the warmth, the life, the potential for greatness or destruction.
"But you must understand—hunger is not wrong, little one. Your mother's corruption was not hunger itself, but hunger without choice, without direction, without love to temper it. The demons who made her into a weapon... they understood this distinction. They sought to remove her choice, to make her pure appetite. And that is evil, Cirrus. That is the truest evil—not desire, but the denial of agency to others."
Then, on the ninth evening, Sullivan shifted. His voice lowered, became conspiratorial, the tone of sharing secrets that shaped worlds.
"There are legends, Cirrus. Stories told to frighten young demons into obedience. Tales of another world, parallel to ours, inhabited by creatures called humans."
He paused, letting the weight of the word settle.
"The legends say humans are weak, fragile, short-lived. They possess no natural magic, no claws, no fangs, no armor. They cannot fly, cannot breathe fire, cannot reshape reality with will alone. And yet... and yet they survive. They build civilizations. They create art, philosophy, technology that mimics magic through cleverness rather than power."
The egg pulsed, and the rhythm was curious, attentive.
"Most demons believe these are only stories. Fables. Warnings about the dangers of weakness and the value of strength. The Thirteen Crowns officially deny that humans exist, and punish those who claim otherwise."
Sullivan leaned closer, his voice dropping to a whisper that vibrated with truth.
"But I know better, Cirrus. I know—because I have seen proof. There was a human, centuries ago, who appeared in our world. No summoning, no contract—simply here, in the Netherworld, lost and frightened and alive in a place that should have destroyed them."
He watched the egg's reaction, the shift in its pulsing rhythm.
"A demon found them. Protected them. Fell in love with them, despite everything—despite the danger, the impossibility, the forbidden nature of such attachment. And eventually... they had a child, Cirrus. A hybrid, possessing both demon longevity and human adaptability, born of a love that should not have been possible."
His hand rested on the egg's surface, gentle, reassuring.
"Humans are real, little one. And they are not lesser—only different. Differently strong, differently wise. Someday, perhaps, our worlds will meet properly, and we will learn from each other. Until then, it is a secret—my secret, now yours. A reminder that reality is always larger than the stories we tell about it."
Nights, he slept in a chair beside the egg, waking at every shift in its pulse, every change in its rhythm. Opera brought him blankets, tea, food he forgot to eat. Opera said nothing, but their ears—cat-ears, expressive in ways their face never was—twitched with worry, with affection, with the particular frustration of caring for a master who refused to care for himself.
---
It began on the twelfth day.
Sullivan noticed it first as a change in the pattern—the egg's pulsing, once steady as a heartbeat, became irregular, sporadic. It would flare with light, then dim to near-invisibility. It would warm against his hands, then cool to temperatures that frightened him.
"Opera," he called, and his voice was wrong, high, frightened. "Opera, something is wrong."
They came instantly, as they always did, their expression calm but their tail lashing. "Sullivan-sama?"
"The egg. Listen to it. Feel it. It is... it is fading."
Opera approached, placed a hand on the shell, and their brows—perfect, arched, usually untroubled—drew together. "The pulse is irregular," they confirmed. "But not weak. Not dying. It is... changing."
"Changing into what?" Sullivan demanded, and he was standing now, towering, powerful, terrified. "I have read everything on nature-spirit reproduction, everything on egg-born demons, and nowhere—nowhere—does it describe this pattern!"
"Sullivan-sama." Opera's voice was sharp, cutting through his panic. "You are not a specialist. You are a generalist, a politician, a warrior. You need expertise."
"Then find me an expert!"
"I already have." Opera produced a mirror from somewhere, activated it with a touch. "Balam Shichiro. Biology teacher at Babyls. Specialist in demonic physiology. And..." a pause, "my junior from our student days."
Sullivan stared, processing. "Balam. The gentle giant. The one who faints at surprises."
"He has matured," Opera said, dryly. "Somewhat."
---
Balam Shichiro arrived within the hour, which meant he had dropped everything, had run, had prioritized a call from his senior above all professional obligations.
He was enormous, as always—taller than Sullivan, muscular in ways that strained his professional attire, his bird-like legs clawing slightly at the floor in his haste. His mask—necessary, to hide the injury that exposed his fangs—was slightly askew, and his hair, usually tamed, was wild from travel.
"Opera-senpai!" he gasped, bowing deeply, formally, the gesture of student to senior despite the years between them. "I came as quickly as I could! What is the emergency? Is it the Chairman? Is he—"
"I am fine," Sullivan interrupted, slightly irritated at being overlooked in his own home. "It is my grandson who concerns us."
Balam straightened, confused. "Grandson? But I was not aware—"
"A recent addition. A promise kept."
Sullivan stepped aside, revealing the egg-chamber on his desk, and Balam's eyes—gentle, curious, fascinated by all living things—widened to impossible size.
"Is that... is that a nature-spirit egg?" he breathed, approaching with the reverence Sullivan had shown twelve days before. "I have read of them, but never seen—May I?"
"Please."
Balam's hands—large, scarred, capable of terrible violence but gentle as a mother's as they lifted the egg—examined it with expertise Sullivan could only envy. He listened to its pulse, felt its temperature, observed the patterns of light within its translucent shell.
"Fascinating," he murmured, more to himself than to them. "The development is accelerating. The mana density is compressing, preparing for hatching. And this signature—" he paused, frowned, "there is something else here. Something beyond the mother's contribution. An external authority?"
"The Heart Tree," Sullivan supplied. "A deity of nature. It transferred some of its power to the child, to aid his development."
Balam's head snapped up, staring at Sullivan with something like awe. "A deity blessing? Chairman, this is... this is extraordinary. The child will be powerful, uniquely so. Capable of healing magic, of nature-manipulation, of communion with green things that other demons cannot hear."
"But the irregularity?" Sullivan pressed, impatient with prophecy, needing facts. "The fading, the cooling—"
"Is normal," Balam reassured, and the word was relief like cool water on burning skin. "For a blessed egg, Chairman. The deity's power is integrating, merging with the child's own developing consciousness. This causes stress, disruption, as the systems adjust. But it is temporary. And it means—" he smiled, genuine, joyous, "it means hatching is imminent."
"Imminent," Sullivan repeated, needing clarification, needing certainty. "How imminent?"
"A week, at most. Two days, at minimum. The process is unpredictable—nature spirits choose their moment, based on factors we cannot measure. Readiness. Safety. The presence of family."
Sullivan absorbed this, nodding slowly. "And until then?"
"Continue as you have. Speak to him. Let him know your voice, your scent, your mana signature. The egg is not merely incubating—it is learning, preparing, bonding. You have done well, Chairman. Better than well."
Sullivan exhaled, tension draining from ancient muscles he had not known were tense. "Thank you," he said, and the words were inadequate, insufficient, but sincere. "Thank you, Shichiro-kun."
Balam blushed—actually blushed, visible even through his mask—at the familiar address. "It is nothing. Opera-senpai called, and I answered. As I always will."
Opera, standing slightly apart, allowed a small smile to curve their lips. "You have improved, Shichiro. You no longer faint at unexpected news."
"I fainted once," Balam protested, with the weariness of long repetition. "Once, senpai, and it was a very surprising discovery—"
"You fainted twice. The second time was at the sight of a particularly large spider.
"It was a dire arachnid! It had sixteen legs!""It was harmless. You were sixteen."
"I was traumatized!"
Sullivan laughed, really laughed, feeling lighter than he had in days, in years, perhaps. "Go," he shooed them, affectionately. "Both of you. Conspire elsewhere. I would speak with my grandson alone."
They departed, bickering quietly, comfortably, and Sullivan resumed his seat beside the egg, resumed his vigil.
"Did you hear that, Cirrus?" he asked, softly. "You have uncles now, of a sort. Family beyond me. Connections that will support you, protect you, teach you what I cannot."
The egg pulsed, and the light within was steadier now, stronger, responding to his voice with recognition.
"A week, they say. Or two days. Soon, little one. Very soon."
He leaned closer, whispering secrets meant only for him.
"I have never been a father," he confessed. "Only a servant, a master, a grandfather-to-be who sought meaning in duty rather than love. But I will learn, Cirrus. I will learn to be what you need. What your mother believed I could be."
The egg warmed against him, and Sullivan closed his eyes, and for the first time since Delkira's disappearance, he allowed himself to hope for a future he could share.
---
The shopping expedition was Opera's suggestion, and Sullivan embraced it with the enthusiasm he usually reserved for new magical theory or embarrassing his colleagues.
"He will need clothes," Opera listed, practical, efficient, as they prepared to depart. "Though we do not know his final form, we can estimate size, estimate growth rate. He will need educational materials—picture books, basic grimoires. He will need toys, stimulation, items to encourage development of his nature affinity."
"And weapons?" Sullivan asked, half-serious.
"Not yet," Opera said, firmly. "Not until he understands consequence."
They traveled to the finest merchants in the demon world, stores that catered to the nobility, the powerful, the discerning. Sullivan bought without looking at prices, without considering practicality, guided by Opera's subtle nods or head-shakes.
A mobile of floating planets for the nursery, each world a perfect replica of a demon realm, orbiting in mathematically precise patterns. Educational, Opera approved. Expensive, Sullivan did not care.
Clothing in sizes ranging from infant to adolescent, fabric woven from spider silk and cloud matter, adjusting to temperature and growth. Practical, Opera noted. Excessive, but necessary.
Books—hundreds of books, from simple alphabets to complex magical theory, from human mythology (Sullivan's secret fascination) to demon history. Picture books illustrated by master artists, stories of heroes and villains and the choices that separated them.
And toys. A miniature Heart Tree that grew real—if tiny—leaves. A set of construct blocks that responded to mana, teaching control through play. A stuffed creature—something between bird and cloud—that hummed lullabies in frequencies soothing to demon ears.
"You spoil him," Opera observed, as they loaded the final purchases into transport storage.
"I do," Sullivan agreed, unashamed. "I will continue to spoil him. I will give him everything I never had the chance to give—" he stopped, corrected, "everything I chose not to give, foolishly, fearfully. I will bury him in love, Opera. I will drown him in attention. I will make absolutely certain that he never, ever doubts that he is wanted, chosen, precious.
"Opera was silent for a moment, rarely at a loss for words. Then: "You fear you will fail him. As you believe you failed others before."
Sullivan stiffened, old pain surfacing. "I have failed before. I was too busy, too perfect, too afraid of imperfection to be present for those who needed me. And they suffered for it. Left for it, perhaps. I will not—cannot—repeat that mistake."
"Then you won't," Opera said, simply. "You are aware now. You are trying now. That is the difference between failure and growth."
They returned to the mansion as darkness fell, the sky above painted in colors that human eyes could not process, shades of purple and green and gold that existed only in the demon world. Sullivan carried the last packages himself—refusing Opera's help, needing the physical burden, the tangible connection to the future he was building.
In the study, the egg waited, pulsing steadily, strongly, readying.
"Soon," Sullivan whispered, arranging gifts he would not open until the moment was right. "Very soon, my Cirrus. And I will be ready. We will be ready."
The mansion settled around them, ancient walls holding new hope, and for the first time in centuries, Lord Sullivan, one of the Three Greats, closest to the throne he refused, perfect demon cursed by his own excellence, allowed himself to believe in happiness unearned, in love unconditional, in family chosen and created and cherished.
The egg pulsed, and the light within was dawn
