Locked in for a Week
During her brief break, her name was Nia. As a commoner, she had no family name. She was the direct disciple of Serianne, the great sage of the Blue Tower. She had no memory of when or how she became her disciple. Simply, at some point when her memories became clear, her master Serianne had called her her disciple. Because of their eerily similar appearances, Serianne sometimes dyed her hair a deeper blue when they were out together. Of course, only then—when they were alone, she was her usual self. It could feel uncomfortable, like looking in a mirror at times.
"Nia, what are you doing here?"
Nia turned her head toward the voice calling her. A woman with pure white hair and eyes that shone beautifully like they held the sky itself. Saintess Elena Serenia. Toward her, who had told Nia to call her Eli casually, Nia stammered as she opened her mouth.
"S-Saintess..."
"I told you to call me casually. Anyway, is something wrong?"
"Uh, that is... um..."
How should she explain this situation? Nia stammered in front of Aya-me's room, another hero. As she rolled her eyes, wondering where to start, a loud noise came from inside the room. It was a bit too lascivious to call it just noise, though.
"Oh my."
"It's... been over an hour like this..."
Over an hour of moans like someone was dying. It might have been going on for two or three hours, or even longer—one round probably being the bare minimum.
Eli blinked at the door a few times before realizing something and murmuring softly as she looked at Nia.
"Ah, Nia hasn't gotten hers yet."
"Uh-eh...?"
"No, nothing."
Thinking about it, the sex Nia had experienced was only ever one or two hours at most. She'd climaxed over and over from just a taste, so she couldn't even imagine going further. To Eli, it had looked like they were really going to die.
"Go see the hero later. It'll be fun."
"Ah, y-yes. Yes?"
"Hehe."
Eli just let out a chuckle and flung open the door to the room where the moans were bursting out.

"It's morning, and you're still at it?"
"Ah, Saintess."
"Oh? If it isn't the Saintess?"
The mage and priestess spoke, breathing a bit roughly.
"Fun's fine, but use soundproofing magic, okay? We can hear everything outside."
"Ah... Yes! We'll be careful!"
"Yeah, we'll be careful."
As soon as they spoke, the mage gestured, casting soundproofing magic over the entire room. Confirming it all with her own eyes, Eli nodded and said,
"Let me know if you need healing."
"Yes!"
After giving them a simple warning and closing the door, Eli turned to Nia with a grin.
"Shall we go to the hero?"
"Eh... uh-eh?"
"Pfft."
Eli just laughed silently at Nia. Nia followed behind her without a word.
As she trailed after Eli, Nia recalled what she knew about her from her memories. Memories that had been planted in her head at some point, just like with everything else. They felt like someone else's recollections, yet also her own—strangely heterogeneous.
Eli was the Saintess of the Holy Kingdom. A genius who graduated from the three-year academy in just one year. She was a candidate for the next Grand Saintess. Her usual demeanor gave off a frivolous vibe, but to the sick or weak, her presence was nothing short of hope. Even as a saintess, blessings that normally took tens of seconds to minutes of chanting were handed out like candy by her. She was called a genius among geniuses.
'Beloved by the gods.' Another nickname for Eli in the Holy Kingdom.
The Holy Kingdom taught that 'the gods love all equally.' For them to call her that, Eli's talents were off the charts. Not the middling excellence that bred envy and jealousy, but an overwhelming gift that made her divine.
That was Elena Serenia from her memories.
"Nia."
"Uh, eh? Y-Yes! Yes?"
"Pfft, hear anything from inside?"
"Eh...?"
At Eli's words, Nia blinked. After spacing out for a moment, she gulped and pressed her ear to the door.
...
...?
"Ah, n-no sound... at all...?"
"Puh, puhahaha! Haha!"
"Uh-eh?"
"Ha, haaah..."
Watching Nia's actions, Eli burst into loud laughter. After laughing so hard tears streamed down, she wiped them lightly with her finger and kept chuckling as she told Nia,
"Of course, heh... she put up soundproofing magic. About a week now? Yeah, that sounds right."
"A-a week? Why didn't I n-notice...?"
"Hee, haa. Curious about inside, huh?"

Nia turned to Eli. She was looking up at Nia with her head slightly tilted. Even though Eli was clearly taller.
Why? As that thought crossed her mind and she looked down at herself, she saw her own body floating lightly in the air. It seemed she'd instinctively levitated.
Slowly channeling her mana to descend to the floor, Nia gave a small nod. There was a tremble, but it was resolute.
"Good choice."
Eli flashed a deep, knowing smile and opened the firmly shut door.
Whoosh—a thick, feminine musk wafted out. It was similar to the scent that had clung to Nia herself after Eli had her back in the Blue Tower.
"Hegooooh♥"
A sour smell. One that tugged at her womb instinctively, stimulating her primal urges.
"Kuh, kooooh♥ O-oh♥"
"Stay still."
"Hii, hooooooh♥"
Kairan was pinning Karni down completely, thrusting her hips deep. Gazing at the hero who had reduced Karni—whose white tiger beastkin blood gave her strength beyond ordinary folk—to a quivering mess of pleasure, Nia swallowed hard. Her lower belly, more precisely her womb, was clenching and starting to ovulate.
"Hngh."
"Ho, hogogoh♥ Kuh, kooooh♥"
"Wonder when you'll get pregnant. I'm curious."
"Hii, hooooooh♥"

The hero, Kairan, crushed Karni's womb and ejaculated deep inside. The thick scent of semen brushed past her nostrils.
"Cast contraception magic, and I'll wreck your womb, got it?"
"Y-Yes, yeees♥"
At Kairan's words, Karni smiled happily and replied softly.
"Ah..."
Thud—her legs gave out. Eli quietly placed a hand on Nia's shoulder. A gentle squeeze. In that moment, one thing was certain to Nia.
She'd be locked in this room for at least a week.
Newberyl Kingdom. A small kingdom located in the southeast of the continent. Originally a duchy, it had seceded from a kingdom destroyed during the great elven invasion 600 years ago. Just a few decades back, at the request of the nobles, the duke of the time had ascended as king, turning it into a kingdom.
"Hmph. Really nothing, huh?"
"Th-That's right. Why would we deal in slaves or whatever!"
Thus, Newberyl II, the second king of Newberyl Kingdom, bellowed at a certain elf.
"This is blatant interference in internal affairs! Newberyl is a sovereign nation!"
"Sovereign nation...?"
"Ughhh!"
The elf let the king's shouting go in one ear and out the other as she rummaged through her memories. With over a millennium of life, recalling specifics took time.
"Ah, I remember. Berry Duchy, was it."
After a bit, she recalled the predecessor to Newberyl Kingdom and spoke with a light smile.
"So you're a descendant of Duke Berry? I clearly remember your ancestor taking up the sword to aid his people."
"Wh-what...?"
"Hmph. Yes, and your laws ban slavery too, so this should suffice. Thanks for the help, Duke."
Over the past week—just one week—that elf had treated the Newberyl Kingdom, with its long history and traditions, like her own home. Investigating anything remotely suspicious, interrogating at will. She'd perused records from past reigns that even the king couldn't access freely, flipped through state secrets, and questioned nobles left and right. When the knight order rushed to stop her and got floored entirely, he'd truly wanted to cry. They'd all recovered healthy soon after—perhaps she'd shown mercy—but that only made it more terrifying.
"Ah, a-aaaah..."
The king checked the documents the elf had just been reviewing.
"Ag-again, state secrets..."
Gazing at the elf leaving the palace from the window, the king made a tearful face.
"I-I, I'm...! ...Not a duke, a king..."
Alone in his office, the king wept for a long while.
A few days after the elf left, news came that the neighboring kingdom had fallen. His resentment turned to fear.
And a week after she departed, reading reports from the military and foreign affairs, the king shook off his terror and began praising the elf.
'Territory doubled!'
The reports suggested they could peacefully annex the recently fallen neighbor. Fear lingered, but a proportional faith was steadily rising.
