Chapter 8
Miss Aiko closed the book with a soft thump, the brittle pages shivering in their leather binding.
For a long moment she sat perfectly still, the way only an ice elf could: back straight, shoulders square, yellow eyes fixed on the curling script she had just finished reading. Only the faint tremor in her fingertips, resting on the book’s worn cover, betrayed the storm inside her.
“Dungeon cores… reincarnated souls… anomalous labyrinths,” she murmured.
Outside, the wind keened across the tundra, rattling the shutters of the little study she had claimed as her own. Frost crept in delicate veins along the window‑glass, spider‑webbing outward every time a gust howled past the settlement.
Miss Aiko rose.
Her chair scraped back over packed‑snow flooring, leaving a thin pale groove. She crossed to the window and pushed the shutters open. A blast of knife‑cold air rushed in, scattering loose papers and making her long blue hair whip around her face.
Below, the ice‑elf settlement glowed faintly in the early evening light: low, curved structures carved into permafrost and stone, roofs dusted with fresh snow, thin plumes of steam rising from communal baths and kitchens. Blue lanterns burned along the main path like captured stars, their light reflecting in the polished ice statues that served as both wards and decoration.
Far beyond, the tundra stretched to the horizon – a white, unbroken sea, dotted only by jagged black rocks and the distant, dim outline of a forest.
Somewhere out there, her students were alive.
She refused to believe otherwise.
Miss Aiko shut the window again, muffling the wind. The study suddenly felt too small, too warm, too full of the past.
The history book on the table stared up at her, its title etched in a language that still felt new on her tongue: On the Nature of Dungeons and the Labyrinth of Yuuno.
“Yuuno,” she said softly.
The name felt wrong and right at the same time – familiar syllables twisted by a foreign accent. On the first day in this new world, when she had woken up with long ears, pale skin, and a faint aura of frost following her every step, she had assumed that the light had claimed her alone.
Then she had found the names.
Buried in the middle chapters, in an offhand list of “notable modern anomalies,” the book had mentioned a young dungeon core whose labyrinth had appeared only a short time ago.
The Labyrinth of Yuuno.
The spelling was different. The pronunciation was strange.
But she knew her students’ handwriting. She knew how they doodled in the margins, how they bent letters without thinking. And she knew—
“That idiot,” she whispered, a fierce rush of affection and fear cutting through her chest. “You really managed to get yourself turned into a dungeon.”
She pressed the heel of her palm briefly against her eyes until the sting there faded. Crying would only make her vision blur; it wouldn’t change anything.
“The others will be here somewhere too,” she said, more firmly now. “Scattered, reborn, wrapped up in trouble. Of course they are.”

Her reflection in the frost‑webbed glass looked nothing like the substitute teacher who had stood in front of class 1‑C back on Earth.
There, she had been an exhausted young woman with ink on her fingers and emergency worksheets stuffed in every pocket. Here, she was taller, thinner, carved in clean, elegant lines like a statue given life. Her hair fell in a curtain of icy blue down her back, braided at the sides in the traditional style of the northern clans. Her ears drooped slightly, the tips brushing the curve of her jaw when she tilted her head.
Beneath the fur‑lined mantle and layered travelling leathers, pale light pulsed faintly under her skin – the slow, steady glow of ice mana.
The elders had called her a blessing when she arrived.
They had called her a weapon once they realised how quickly she absorbed their magic.
Now, they were going to call her something else entirely: a problem.
Miss Aiko straightened, squared her shoulders, and began to pack.
She moved with the same efficient energy she had once used to throw together lesson plans ten minutes before the bell. Satchel first: a tough leather bag enchanted against frostbite, lying folded on a low shelf. She slung it onto the table and began filling it with what she would need.
Dried rations. A stoppered flask that kept water from freezing. A compact healer’s kit she had bartered for with two weeks of tutoring. A folded map of the region, edges fraying from frequent use. Three slim spellbooks – one for ice evocation, one for barriers and support magic, and one for the strange hybrid runes she had been quietly developing on her own.
At the very bottom, under a spare set of gloves, she tucked the history book.
She hesitated over that, fingertips resting on the cover again.
The rational part of her knew it was just a book, written by some scholar who had probably never set foot in Yuuno’s labyrinth. The emotional part of her kept seeing a nervous boy in the back row, flinching when called on but lighting up when the topic turned to ancient wars and tactics.
“If this is you,” she murmured, “I’m going to drag you out of there, dungeon core or not.”
Her breath fogged the air in front of her as she spoke, swirling like a tiny, private storm.
A knock sounded at the door.
Miss Aiko froze, then exhaled slowly and turned.
The door creaked open before she could answer. An older ice elf stepped in, his hair white as the snow outside, his long ears bound in simple silver cuffs that jingled softly when he moved. Elder Seryn, keeper of records, had been the first to show her the library.
His yellow eyes swept over the room, taking in the half‑packed satchel, the missing books, the open cloak chest.
“So,” he said mildly, “you are leaving.”
Miss Aiko considered lying.
She discarded the idea at once. She had always been a terrible liar, in any world.
“Yes,” she replied. Her voice came out clearer than she had expected. “I’m going to find my students.”
Seryn studied her for a long moment.
“You are not from here,” he said at last. It wasn’t quite a question.
“No,” she agreed. “But they are my responsibility. Whatever gods or systems or cosmic bugs thought it was a good idea to scatter a classroom across your world… they didn’t ask me first.”
The corner of Seryn’s mouth twitched, the ice‑elf version of amusement.
“Your attachment to these… ‘students’… is unusual,” he said. “Most who reincarnate leave the past life behind.”
Miss Aiko thought of Mai’s nervous smile, Okama’s stubborn shoulders, Yuuno shrinking into his seat whenever someone loud walked past. She thought of the empty chairs that had followed the white flash of light.
“I was their teacher,” she said. “I don’t get to leave them behind.”
Silence stretched between them, filled only by the soft hiss of her breath and the distant rush of the wind. Finally, Seryn sighed.
“You have brought much knowledge to our settlement,” he said. “We owe you. But the lands beyond the tundra are not kind to wanderers.”
“I’ve noticed,” she said dryly. “Between the wyverns, the mana storms, and the bandit guilds, your world has… an interesting curriculum.”
One of his eyebrows lifted.
“You intend to cross the White Expanse, descend through the frost‑rim forest, and reach the human kingdoms alone?” he asked.
“Yes.”
“Foolish.”
“I’m aware.”
Another long pause…
Then he stepped further into the room and placed something small and cold on the table beside her satchel.
