I Enslaved The Goddess Who Summoned Me

The Kingdom of Kastoria.

Many throughout the Holy Continent would consider its capital the most breathtakingly beautiful city in existence, and with considerable justification. The entire urban landscape was defined by unique and exquisite traditional architecture that perfectly embodied the aesthetic vision of the kingdom said to have been founded directly by the Goddess Amaterasu herself.

Everything about Kastoria’s design reflected her divine influence—it was constructed entirely to her image, creating what could only be described as a bright, radiant kingdom that seemed to glow with inner light even on overcast days.

For the Heroes of Kastoria who had originally come from Japan—summoned from modern Earth three years ago through divine intervention—arriving in this capital had been a profoundly disorienting yet oddly comforting experience. When they first laid eyes on the city, they couldn’t help but feel a sense of deep familiarity, a recognition that this place wasn’t entirely foreign despite being in a completely different world.

Obviously, Kastoria’s capital looked vastly different from the modern Japan they had grown up in, with its towering skyscrapers, advanced technology, omnipresent anime culture, and contemporary urban development. There were no electronics, no cars, no convenience stores on every corner.

But the architectural DNA was unmistakably, fundamentally Japanese in character and spirit. It looked like Japan—or more accurately, like a medieval version of Japan that had never experienced industrialization or Western influence.

Yet it was somehow even more than that. This was a bigger, grander, more magnificent version of medieval Japan—like a legendary kingdom torn directly from Japanese folklore and mythology, brought into physical reality with divine craftsmanship.

The capital especially embodied this fantastical quality, looking simultaneously authentic and impossibly idealized.

Men and women moved through the streets dressed in traditional garments—kimono, hakama, and other classical Japanese clothing styles, all crafted from high-quality fabrics that suggested widespread prosperity. Everyone appeared well-fed and comfortably wealthy, their clothing clean and well-maintained, their bearing confident and content.

Sakura trees had been planted systematically throughout the entire city in beautiful, precisely arranged rows. The flowering cherry trees lined every major street and filled numerous parks and public spaces, creating tunnels and canopies of pink and white blossoms during blooming season. Even now, outside the peak flowering period, the graceful trees provided shade and aesthetic beauty that elevated the entire urban environment.

Every street was remarkably lively and animated with activity. Markets bustled with commerce, children played in open squares, artisans displayed their crafts, performers entertained crowds. The atmosphere was one of genuine prosperity and communal happiness rather than the grim subsistence that characterized so many medieval cities.

The entire capital resembled a beautiful fortress—not in the sense of being militaristic or unwelcoming, but in conveying strength, security, and careful planning. The city walls were formidable yet elegant, the defensive positions integrated seamlessly into the aesthetic design.

Dominating the center of this magnificent capital, rising above all other structures with commanding presence, stood the royal castle. This was no ordinary fortification—it was genuinely gigantic, a sprawling complex of interconnected buildings that would have dwarfed most European castles. The architecture followed classical Japanese palatial design but executed on a scale that suggested divine rather than merely human construction.

The castle served as home to Kastoria’s royal family, but for the past three years it had also housed the summoned Heroes—those Japanese teenagers and young adults pulled from their modern lives and thrust into this fantasy world to serve as the kingdom’s champions and defenders.

In one of the castle’s most significant chambers—the main throne room, beautifully crafted with elaborate woodwork and elegant simplicity—the space currently stood empty except for a single occupant.

A woman of extraordinary, almost otherworldly beauty stood motionless near the center of the vast chamber. She had long, flowing dark hair that cascaded down her back like a waterfall of midnight silk, and her eyes were a striking, luminous white that marked her unmistakably as something beyond ordinary humanity.

This was Kaguya, one of the most important and revered figures in all of Kastoria. She held a position that transcended normal political or religious hierarchies—she was regarded as something approaching a living saint, her words carrying immense weight throughout the kingdom.

The people of Kastoria believed her to be the daughter of the great Goddess Amaterasu herself, making her divine blood rather than merely mortal. Whether that claim was literally true or symbolic didn’t particularly matter—the population accepted it as fact, and her presence radiated an aura that made doubt seem impossible.

Her divine beauty was so profound, so overwhelming in its perfection, that it made people instinctively kneel in her presence. Her every command was answered immediately and without question, not through fear but through genuine reverence and desire to please someone so clearly touched by divinity.

As was typical for her, Kaguya showed minimal emotional expression. Her face remained serene and composed, beautiful as a statue carved by master sculptors but just as still and unreadable. She stood gazing thoughtfully at the empty throne, apparently lost in contemplation about matters known only to herself.

After several minutes of this meditative stillness, the throne room’s doors creaked open behind her, admitting a new presence.

A beautiful woman entered with a warm, genuine smile lighting her features. She had long black hair arranged in an elegant traditional style and expressive brown eyes that sparkled with maternal joy and contentment.

It was Princess Haruka, the current heir to Kastoria’s throne and one of the kingdom’s most beloved figures in her own right.

Cradled securely in her arms was a baby boy—perhaps a year old, still small and precious and completely dependent. His name was Ryuuji, the son she had given birth to with Ryuuki, who served as the leader of the Heroes summoned to Kastoria three years prior.

The baby was making soft wailing sounds—not distressed crying but the fussy noises infants made when they wanted attention or were mildly uncomfortable about something.

Hearing little Ryuuji’s vocalizations, Kaguya turned around smoothly to face the princess and child. For the first time since standing alone in contemplation, a faint but genuine smile appeared on Kaguya’s normally expressionless lips.

That small smile transformed her face entirely, warming her divine beauty into something more approachable and human, revealing affection beneath the serene mask she typically wore.

“Kaguya-sama,” Princess Haruka greeted with deep respect, bowing her head gracefully despite holding baby Ryuuji securely against her chest. The gesture was practiced and sincere, demonstrating the genuine reverence she held for the divine woman before her.

“Haruka,” Kaguya acknowledged warmly. “How is he doing? The child grows well, I trust?”

She began approaching them with smooth, gliding steps that seemed almost too graceful to be entirely human.

“He is doing exceptionally well and remarkably healthy, Kaguya-sama,” Haruka replied with a radiant smile, looking down at her baby boy with the unmistakable expression of complete maternal adoration. “He eats well, sleeps soundly, and grows stronger every day. I couldn’t ask for a healthier son.”

Kaguya reached them and extended one pale, elegant hand toward little Ryuuji. Her fingers were long and delicate, moving with precise control as she gently stroked the baby’s head with tenderness.

“He will grow into a formidable man,” Kaguya said “And more importantly, he will become a formidable King for Kastoria—strong, wise, and beloved by his people. I can see the potential already forming in him.”

“He will definitely live up to that destiny,” Haruka agreed happily, her pride in her son evident in every word. “With Ryuuki’s strength and my royal bloodline combined, he carries the best of both lineages.”

The political significance of this child could not be overstated. Haruka was the current legitimate heir to Kastoria’s throne, but obviously she was expected—indeed, required by tradition and practical governance needs—to marry and produce a male heir who could eventually assume the kingship.

The throne had stood empty for five long years now, ever since Haruka’s father had been assassinated under circumstances that had nearly torn the kingdom apart. During that dangerous period of instability, the kingdom had been guided and effectively ruled through Kaguya’s wisdom and divine authority.

But that arrangement, while functional, couldn’t continue indefinitely. People were beginning to question the situation despite their immense respect for Kaguya. A kingdom needed a proper king, not just a regent or advisor, regardless of how divinely blessed that regent might be.

But now, finally, the solution had arrived in the form of baby Ryuuji.

Haruka, as crown princess, had given birth to a child conceived with Ryuuki—the strongest of all the summoned Heroes, chosen and blessed directly by Goddess Amaterasu herself. The symbolism was perfect, the legitimacy unquestionable.

Their child represented the perfect fusion of Kastoria’s ancient royal bloodline with the divine favor represented by the Heroes. No one could possibly dispute his right to eventually rule. The political and religious legitimacy couldn’t be more ironclad.

In fact, the entire kingdom had erupted in celebration upon hearing news of Haruka’s pregnancy, and the joy had only intensified when the baby was born and revealed to be a boy—a proper male heir to continue the royal line.

“Did you wish to hold him, Kaguya-sama?” Haruka asked then, shifting her grip slightly as though preparing to transfer the baby. She wondered if that might be why Kaguya had summoned her to this private meeting. “He’s been quite calm today—this would be a good time.”

“No, that’s not why I called you here,” Kaguya replied, her expression shifting back toward seriousness as she withdrew her hand from stroking Ryuuji’s head. “I summoned you to inform you of an important decision. We will be holding a grand ceremony very soon—calling together all the noble houses and presenting the child publicly to the people as their future King.”

“Already?” Haruka asked with obvious surprise, instinctively looking down at her smiling baby who seemed blissfully unaware of the weighty destiny being discussed. “But Kaguya-sama, he’s still just an infant. Surely we could wait until he’s older, more aware?”

“Yes, he is still very young,” Kaguya acknowledged calmly. “But the people need to see and recognize their future King now. They need concrete assurance that the royal succession is secure, that the uncertainty of these past five years is definitively over.”

Her luminous white eyes held Haruka’s gaze with gentle but unyielding intensity.

“It has been five years already that the people have waited and endured without a proper King on the throne,” Kaguya continued. “Five years of uncertainty, whispered doubts, anxiety about the kingdom’s future. There cannot be a better timing or more perfect moment than right now to reassure them completely. We must seize this opportunity while the joy of his birth is still fresh and the symbolism is most powerful.”

Haruka still seemed somewhat concerned, her maternal instincts making her protective about exposing her infant son to the pressures and scrutiny of public ceremony. But intellectually, she couldn’t disagree with Kaguya’s strategic reasoning.

Since her father had been assassinated five years ago the political situation in Kastoria had become dangerously tense. Various noble factions had jockeyed for influence, some questioning whether the royal line should continue at all, others proposing alternative succession arrangements.

Kaguya’s sudden appearance and assertion of divine authority had calmed much of that dangerous tension, providing stability when the kingdom had been on the verge of fracturing into civil conflict. Her presence had been nothing short of miraculous in preventing disaster.

But even Kaguya’s divine backing couldn’t sustain an empty throne forever. The royal bloodline needed to demonstrably continue. The people needed to see their future secured through proper hereditary succession.

“If Kaguya-sama believes this is the right course, then I trust your wisdom completely,” Haruka finally said with a warm, accepting smile. “You’ve guided us safely through so much already. I’ll prepare myself and Ryuuji for whatever ceremony you envision.”

“Good. I’m pleased you understand the necessity,” Kaguya said with approval, the faint smile returning briefly to her serene features. “You may inform the Heroes of this development as well. Their presence at the ceremony will be essential—particularly Ryuuki, of course, as the child’s father. The people need to see the unity between the royal house and the divinely summoned champions.”

“I’ll speak with them immediately,” Haruka promised, nodding her understanding of how the various political and symbolic elements needed to align.

With a final respectful bow—made somewhat awkward by the baby in her arms but executed with practiced grace nonetheless—Princess Haruka turned and departed from the throne room, her footsteps echoing softly in the vast chamber as she left.
