Work Text:
Hanagaki Takemichi had never cared much for history.
As a university student perpetually drowning in assignments and paperwork, he felt more like a ghost than a scholar. His current misery was a compulsory field trip to an ancient palace from the Sano Empire era—a trip his professor insisted would 'enhance cultural analysis' for their final project.
Takemichi only heard three words—work, work, and more work.
The palace had long ago been converted into a museum, its corridors lined with polished wood and a heavy, quiet reverence. Tourists shuffled past velvet ropes while security cameras blinked lazily from the corners, modern eyes watching an ancient world.
“Oi, Takemichi!” Takuya called, nudging him with an elbow. “Stop looking like you’re about to collapse. It’s just a field trip.”
“I have three deadlines next week,” Takemichi muttered, his shoulders slumped. “If I do collapse, just bury me here. At least the surroundings are historic.”
They shared a laugh as they wandered deeper into the estate, eventually entering what had once been the imperial bedchamber.
The air felt different there. Thicker. Older.
At the center of the far wall hung a massive painting encased in protective glass. It depicted the Emperor and his Empress, but the Empress was undeniably male.
In ancient times, humanity had possessed secondary genders—Alpha, Beta, and Omega. Back then, it was not strange for a man to become a spouse, to bear a child, and to rule beside an emperor. But as centuries passed and the world modernized, those secondary genders faded into myth. Alphas and Omegas vanished from the gene pool until only Betas remained, divided simply into male and female.
Evolution or extinction—no one truly knew.
Takemichi stepped closer.
The Emperor’s hand rested gently at the Empress’s waist. The gaze in his painted eyes wasn't one of political duty. It was absolute worship.
“Bro,” Akkun said behind him, his voice dropping an octave. “Why does the Empress look exactly like you?”
Takemichi snorted. “Shut up.”
“No, seriously.” This time it was Yamagishi. He adjusted his glasses, trying to look like a genius despite the reality of his grades.
The others gathered around, murmuring in realization. Takemichi rolled his eyes and leaned closer to the canvas.
The same soft eyes. The same mouth. Even the slight, hesitant tilt of the head. For a second, something in Takemichi's stomach dipped—a strange, hollow sensation.
Then he laughed it off. “What, you think I’m royalty reincarnated or something? Imagine me bossing around a whole empire.”
Makoto grinned. “You’d cry in the first council meeting.”
“Hey!”
They laughed, the tension breaking. Takemichi didn't think much about it for the rest of the tour. He didn’t notice the way the air in the bedchamber seemed to follow him when he left, nor the faint chill trailing down his spine. He certainly didn't notice the prickling sensation of being watched.
Back at the dorm that night, he opened his laptop. He told himself it wasn't because he was unsettled, it was just 'research' for his assignment.
He typed into the search bar: Sano Empire Emperor and Empress history.
The articles loaded slowly. Arranged marriage, one entry read. A political union between noble houses.
But something else caught his eye: The Emperor fell in love at first sight.
Takemichi frowned, scrolling further.
Historical records describe the Emperor as deeply devoted to his Empress. The union, though arranged, became one of rare affection. The Empress conceived their first heir within the first year of marriage.
Takemichi leaned closer to the screen, the blue light reflecting in his wide eyes.
However, shortly after giving birth to the Crown Prince, the Empress fell gravely ill. The illness was unknown. Records state the Empress endured months of suffering within the imperial bedchamber before passing quietly in the night.
Takemichi’s fingers stilled on the trackpad.
Following the Empress’s death, the Emperor refused to take a concubine or remarry. He devoted himself entirely to raising the prince. He eventually died in the same bedchamber, reportedly never recovering from his grief and heartbroken.
Takemichi swallowed hard. The same bedchamber. The one with the painting.
A cold sensation brushed his shoulder, like a phantom breath. He stiffened, his heart hammering against his ribs. Slowly, he turned around.
The dorm room was empty.
“…Okay. Not funny,” he whispered to the silence.
He shut the laptop and scrambled into bed, pulling the blanket up to his chin like a child warding off ghosts. That night, he dreamed of heavy silk, the scent of smoke, and someone calling his name in a voice that didn't belong to this century.
By the following week, the pull became unbearable. It was a physical ache in his chest, a magnetic force dragging him back to the palace.
"Takemichi! Hey!" Akkun called out as class ended, but Takemichi didn't hear him. He was already sprinting toward the train station, fueled by a desperation he couldn't explain.
He reached the palace just as the sun began to dip below the horizon, painting the stone walls in blood-orange hues. The tourists were gone. The silence was absolute. He didn't stop until he reached the bedchamber.
The painting stood exactly where it had been. The Emperor. The Empress. The resemblance was undeniable now, it was like looking into a mirror across time.
Takemichi stepped toward the glass.
“…If this is some kind of cosmic joke,” he murmured, his voice trembling, “it’s not funny.”
The air grew heavier—warmer and thicker than before. His reflection in the glass flickered strangely, overlapping with the Empress’s painted face.
And then—
A hand touched his shoulder. It was cold, solid, and felt ancient.
Takemichi’s breath caught. He spun around, but again, there was no one there. A sickening sense of déjà vu washed over him.
When he looked back at the painting, the Emperor’s eyes seemed closer. More focused. Alive.
The room tilted. The floor seemed to liquefy beneath his feet, and darkness swallowed his vision whole.
The world dissolved into ink.
When Takemichi’s vision finally cleared, the museum smell—that faint, ancient dust clinging to stone and varnish—had vanished. Gone were the velvet ropes, the 'No Photography' signs, and the plexiglass barriers shielding forbidden spaces from curious hands.
He was no longer sprawled across a cold, linoleum floor.
Instead, he lay atop a mountain of silk futons, the fabric cool and impossibly soft beneath his trembling fingers. The air was warm, thick with the drifting, bittersweet smoke of medicinal herbs.
This wasn’t an exhibit. It was alive.
Then he noticed something else. Beneath the herbal smoke lingered another scent—deep, smoky, and spiced. It was unfamiliar, yet overwhelming, wrapping around him with an intimacy that felt both terrifying and steady. He could hear someone breathing nearby. Slow. Heavy. Certain.
And somehow, impossibly, he could feel it.
The presence pressed against his awareness as though a new sense had awakened inside him—something beyond sight or sound. Instinct flooded his veins, not learned or logical, but animalistic. His body understood a language his mind did not.
He tried to scramble upright, but his body refused.
He felt weighted, sluggish, and wrong in ways he couldn’t name. Panic fluttered in his chest as he looked down—and his breath snagged painfully in his throat.
His hoodie and jeans were gone. In their place, twelve layers of ceremonial robes cascaded over him in a waterfall of gold, crimson, and white. The silk was heavy, regal, and suffocating. Each layer seemed to whisper of authority, ownership, and crushing expectation.
His pulse thundered. The room was familiar, yet not. It was the same bedchamber from the museum, but no ruin remained. The wood gleamed with fresh polish, the paper screens were intact and pristine. Every surface was luxurious and inhabited.
This was the Sano Empire, breathing around him. A living era.
He forced his trembling hands beneath the layered robes, desperate to anchor himself to something real—anything.
He froze.
His abdomen curved outward, high and firm beneath the Empress’s gown. Heavy. Undeniable. It was the unmistakable fullness of a body on the verge of birth.
“What..” He whispered, but even his voice sounded softer, rounded by the perfumed air.
As if answering his disbelief, something shifted inside him. A sharp, rhythmic kick pressed against his palm.
Before he could process the shock, he sensed someone at the door. A pheromone pressed against the edge of his awareness—familiar, personal, and irresistible. It was someone he recognized, though he had never met them in his life—someone his soul felt inexplicably tethered to.
The door creaked open slowly, as if the person feared disturbing a fragile peace. Every fraction of movement sent shivers along Takemichi’s heightened senses.
“Are… you awake?”
The voice was soft and measured, but threaded with a jagged edge of concern. Takemichi froze, his breath hitching.
Then he saw him.
Emperor Manjiro.
He was exactly as the museum portrait had depicted—sharp, regal, and hauntingly breathtaking—but the paint had lied about the eyes. They weren't cold glass, they were dark, swirling pools of exhaustion and terror. They were the eyes of a man commanding an empire but failing to protect what mattered most. The smoky spice scent clung to him, now tinged with the bitterness of worry.
Takemichi’s pulse skipped a beat.
“I… I am,” Takemichi stammered. He tried to sit upright, attempting to sound calm and casual. “I—uh… I just… woke up.”
Manjiro stepped closer, his eyes scanning the layers of silk that draped Takemichi before lingering on the swelling curve of his belly. His gaze was gentle, protective, yet laden with unspoken questions.
“You do not seem well,” Manjiro said carefully. “The servants—no one dared disturb you. I feared…” His hand hovered in the air, uncertain, almost brushing Takemichi’s arm. “I feared for you.”
Takemichi swallowed hard, heat blooming across his face. “I… I’m fine. Really,” he said, forcing a light, awkward laugh that sounded clipped in the quiet room. “Just… heavy sleep, I guess.”
Manjiro’s eyes narrowed slightly, studying him. Concern knitted his brow. “Your hands… your breathing… the medicine… you are not entirely yourself, Empress. Have you eaten? Taken tea?”
Takemichi forced himself to nod, his heart hammering against his ribs. He could feel Manjiro’s pheromones—steady, grounding, and intimate—pulling at something primal deep inside his chest.
Manjiro’s gaze softened, lingering a moment too long. “Rest. I will remain near. Do not force yourself.”
Takemichi felt a stir inside him—a kick, sharp and insistent, echoing his own internal panic. He swallowed, clenching his fists under the silk to hide their shaking.
“Yes,” he whispered, nodding as his cheeks burned. “I… I will.”
Manjiro finally stepped back, still watching, still hyper-aware of Takemichi’s every movement. Takemichi lay back down, his mind spinning in a dizzying reel.
He was trapped.
He was in the body of an Empress in the Sano Empire. He was mere feet away from an Emperor who had no idea a modern soul was hiding behind his wife's face—and he was carrying an heir that, according to history, he wouldn't live to raise.
