I see my dead childhood friend standing on an ice world at the edge of the Solar System.

  It’s just a photo in a news article—pixels and compression artifacts—yet my chest tightens like someone’s reached inside and grabbed my heart.

  No one else in this lecture hall seems to notice the end of the world.

  Before class starts, I do what I always do: flip open my laptop and scroll.

  The light-field OLED screen swallows black so deeply it feels like a hole. Headlines slide past under my fingertip—politics, celebrity divorces, yet another startup promising immortality.

  Around me the room hums with ordinary noise. Someone in the next row laughs at a video on their phone. Winter sunlight leans in through the window, catching dust motes and turning them into glitter. It should be pretty. It should make me feel something.

  Lately, nothing does.

  Since Mii died, the world has been a muted film. Lectures, conversations, meals—everything happens a few feet away, like I’m watching my own life through glass.

  Then one headline stops my thumb.

  JAPAN’S SOLAR-SAIL PROBE REACHES KUIPER BELT OBJECT “IZANAMI”

  Izanami.

  Even the name smells like death—goddess of the underworld, the one who waits on the far side. My pulse gives a small, stupid jump, and I click.

  The article opens with a glossy CG render: a probe unfurling a square sail, paper-thin, catching sunlight like a kite and using that pressure to push itself beyond the planets. It’s the kind of thing I loved as a kid, the kind of future my generation was promised.

  According to the piece, the probe launched twenty years ago. It passed Pluto, kept falling outward, and finally reached an object deep in the Kuiper Belt.

  Izanami is about a quarter of Pluto’s size. Its surface is bright ice, fractured by countless scars. There might be a liquid ocean below. The usual breathless speculation.

  I scroll.

  There’s a photo.

  A small lander, barely larger than a shoebox, took it after touching down. White plain. Far-off black rifts—ink spilled across snow. Starshine reflecting off ice, giving everything a pale blue sheen.

  And in the corner—

  Something upright.

  My skin goes cold.

  “…Huh?”

  I pinch-zoom until the image breaks into blocky squares. The outline should dissolve into noise. Instead it sharpens into a shape my brain refuses to let go of.

  A slim figure. Narrow shoulders. Long hair. Clothes that look like something from years ago.

  I blink. Look again.

  My throat constricts.

  It looks like Mii.

  Not “a girl,” not “someone,” not a trick of shadows. Mii—my Mii, the one who died before she even made it to campus.

  “Oy,” I whisper, leaning toward the guy next to me. “Doesn’t that look like a person?”

  He lifts his face from his phone and squints at my screen. “Mmm. Yeah, kind of human-shaped.” He scratches his cheek. “But it’s probably a shadow in the snow. And if the scale’s right, that ‘person’ would be, like… a hundred meters tall.”

  “So you think it’s nothing.”

  “I think you want it to be something.”

  He turns back to his phone like he’s done his good deed for the day.

  The heater is blasting, but sweat slides down my spine.

  The classroom door opens. The lecturer walks in with a stack of papers. Chairs scrape, conversations die.

  I snap the browser shut and open my notes, like I can hide from the image by pretending to be a normal student.

  But the white plain stays burned behind my eyes.

  Why would she be there?

  It’s impossible.

  And yet my chest won’t accept impossible as an answer.

  The lecture starts. Quantum mechanics. Hamiltonians. Eigenvalues. Symbols pile up on the board like a language meant to exclude human feelings.

  My pen moves. My hand shakes.

  All I can see is an ice world and a girl who shouldn’t exist.

  When I say her name in my head—Mii—the dull ache returns, spreading through my ribs like slow poison.

  Back in my room, I pull out the framed photo I’ve kept facedown on my desk for months. I wipe the dust away and set it upright.

  There she is, smiling into summer light. White dress. Hair catching the sun. For a second the air tastes like cicadas and river water.

  We met in elementary school, in the corner of the library.

  I was reading a book about space—planets, nebulae, the kind of thing that made the universe feel like a story that never ended. She sat down beside me, leaned in, and asked, “Is it fun?”

  Her voice was clear and soft, like wind chimes.

  After that we were inseparable—after-school parks, riverside walks, and summer festivals with our families.

  Mii loved drawing. I loved talking about stars. She listened like I was telling her secrets.

  “Do you think space goes on forever?” she asked me once, eyes bright.

  “I don’t know.”

  “Maybe if you go far enough, you loop around and end up under the ground.” She said it casually, like it was obvious. I remember it even now.

  Middle school came and we stayed close. High school nearly split us—her parents transferred for work, and she moved away. It hurt, but we wrote letters anyway—little lifelines across distance.

  During winter and summer breaks she came home. When I saw her at the station my heart always kicked, stupidly happy, like it was trying to climb out of my chest. Her hair grew longer. She got taller. Her smile stayed the same.

  We talked about the future.

  “Let’s go to the same university,” she said.

  It became my anchor. Something to aim at.

  And then—somehow—we did it. We both passed.

  This content has been unlawfully taken from Royal Road; report any instances of this story if found elsewhere.

  The day I saw my acceptance letter, I called her immediately. Through the receiver I heard her squeal.

  “We did it! We can commute together!”

  I laughed, nodding even though she couldn’t see me. “Yeah. Together.”

  Spring was a few weeks away.

  Then the future was stolen like it had never belonged to us.

  Mii died in a traffic accident a few weeks before entrance ceremonies—blamed on a self-driving AI glitch, rare enough to make the news.

  None of that mattered. All I saw was her name, repeated in cold type.

  At the funeral she lay surrounded by white flowers, face calm like she was asleep. I couldn’t speak. I couldn’t cry. It didn’t feel real. It felt like the world had simply… removed her, and no one was allowed to question it.

  After that, nothing moved me.

  I got into college. Life started. And I walked through it like a ghost, watching my own body attend lectures and answer people with the right words.

  I stare at her photo until my eyes burn, then exhale like I’ve been holding my breath for a year.

  I want to go somewhere I’ve never been. Somewhere that matches how empty I feel.

  On a whim I pull an old darts set from the bottom drawer. There’s a map on the wall. I throw.

  The dart sinks into a random spot—some regional city I’ve never even heard of.

  I check routes. Two hours by linear maglev, then a local line for another hour.

  “Am I really doing this?” I ask myself.

  My fingers tremble as I book a ticket. When the reservation confirms, I swear I hear a small sound in my chest—like something clicking into place. Determination, maybe. Or just a cleaner form of escape.

  I pack and leave.

  The winter air stings my cheeks as I walk to the station, checking the timetable over and over like I’m afraid the train will vanish if I look away.

  The underground maglev platform is all sleek light and floating signage. Behind glass, the train waits—white, streamlined, almost unreal.

  Once it moves, the windows turn into screens—most of the route is underground—showing the surface in real time. City towers peel away. Snowy mountains replace them.

  I try music, give up, and just watch the landscape like it might teach me how to feel again.

  The local line feels like stepping back a century: old smell, worn seats, scratched windows, a slow fuel-cell hum.

  Passengers sit in silence. The train crawls through snow-covered streets and shuttered shops, as if the world is quietly giving up.

  I search my destination.

  The city has a preserved historic district for tourists. But it’s off-season, so it’s dead. The population has been falling for years—every year, tens of thousands fewer people.

  “Yeah,” I mutter. “Sounds right.”

  A colorless world for a colorless me.

  At the station, wind slaps my face. Old signs line the street, clinging to a faded, mid-century optimism. My hotel is a five-minute walk. The clerk hands me a physical key like a relic.

  The room is bare—bed, desk, a small chair by the window. Outside, rooftops catch the last red light.

  I sit and listen to the silence. My heartbeat sounds loud.

  Even here, the emptiness follows.

  But the world is… different. Just enough to be unsettling.

  At dusk I go out again. The preserved buildings have a little charm. Power lines are buried. It’s been cleaned up, curated.

  The arcade shopping street is dim and nearly empty. Most shutters are down. My footsteps echo like I’m trespassing in someone else’s abandoned life.

  I spot a small eatery with a short doorway curtain and duck inside.

  “Welcome,” the owner calls. Bald guy in a work jacket, mid-aged, voice rough but not unkind.

  The place is clean, wood-scented, warm. I take a seat at the counter and order hot sake.

  That’s when the door opens again.

  A man walks in wearing a stylish jacket, private clothes that still look expensive. His hair is threaded with white. Thin silver-rim glasses. He greets the owner like they’re acquaintances.

  “Evening—what’s good tonight?”

  I know his face.

  I can’t stop myself. “Professor Sato?”

  He turns, surprised, then his expression softens. “Oh? You know me? That makes me happy.” He slides onto the stool next to mine. “Are you one of my university’s students?”

  “No, sir. I’m at my university.” I name mine. “I read an interview with you in a science magazine.”

  “Well, fancy that.” He smiles, easy and warm. “Didn’t expect to be recognized in a town like this.”

  The owner pours hot sake, steam curling into the air. The warmth from the counter seeps into my fingers.

  “You came from far away,” Professor Sato says, taking a sip. “What brings you here?”

  I force an almost-joking tone. “Heartbreak tourism.”

  My voice comes out dry anyway.

  He doesn’t press. He just nods like he understands more than I’ve said, and drinks.

  “It’s good sake,” he says simply.

  For the first time in months, something—anything—feels like it’s entering my body instead of sliding past it.

  Conversation drifts, as it always does, to the headline everyone’s been sharing.

  “The probe reaching Izanami is incredible,” I say. “Twenty years on a solar sail.”

  “It is,” he agrees, and there’s quiet heat in his voice. “Solar sail plus a tiny radioisotope cell. Twenty years ago people called it fantasy.”

  My throat tightens. I hear myself ask the question I’ve been trying not to ask.

  “But… you saw the photo, right? People are saying there’s a human figure in it.”

  I aim for casual. I fail.

  Professor Sato sets his cup down. For a moment he looks like he’s listening to something far away.

  “…It might be possible,” he says at last.

  “What?”

  “Not scientifically,” he adds quickly, then smiles as if amused at himself. “Or rather—what I mean is… it overlaps with something I’ve been thinking about lately.”

  He leans back, fingers around his cup like it’s a hand warmer.

  “I’m chasing the nature of dark matter,” he says. “You know the basics, right? The mass we can’t see, outweighing visible matter by several times.”

  “Yes. Axions are one candidate.”

  “Exactly.” His eyes brighten. “Axions are extremely light. They barely interact with ordinary matter, so direct detection is difficult. But I’ve been wondering if they’re not just ‘spread out.’ If they have structure.”

  “Structure?”

  “My latest simulations suggest axions behave like a fluid.” He draws an invisible line along the counter with his fingertip. “And the flow—this is the interesting part—seems to stream out from the Sun, past the inner planets, past Pluto, and keeps going like a river. Even more: the flows might connect between star systems, like a network.”

  I hold my breath without realizing it.

  “If we could see it with our eyes,” he continues, “we might see a real river in the night sky. More like a river than the Milky Way ever was.”

  The phrase slips out of me, uninvited. “A dark river.”

  Professor Sato laughs softly. “Yes. The River Styx. Sanzu River. Yomotsu Hirasaka. Humanity has always told stories about a river that separates the living from the dead. Maybe those myths were a kind of intuition about phenomena like this.”

  My heart beats hard enough to hurt. “So… do the dead cross that river? Do they… end up out there? On Pluto, on Izanami?”

  He rotates his cup slowly, thinking.

  “As a scientist,” he says, gentle, “I can’t claim that.”

  Then, quieter: “But the universe is more poetic than we like to admit.”

  The words land in my chest and stay there.

  At the end, he adds one more thing, as if it’s an afterthought.

  “Come to grad school,” he says. “People who can’t stop looking at the sky are rare. We need them.”

  I manage a vague smile. I can’t answer. But somewhere deep inside, something that’s been dormant stirs.

  Back in my hotel room, I shower and collapse onto the bed.

  The hot sake has left warmth in my hands. Outside, the small city’s night is quiet enough to hear distant trains. The sound fades. Silence pours in.

  I close my eyes.

  Dark river.

  Professor Sato’s words echo in my skull. If that river is real, then where is Mii flowing now?

  The image of the ice plain returns.

  As sleep takes me, the world flips.

  I’m standing on the deck of an old sightseeing boat.

  The metal is crusted with ice. The handrails are rusted and cold under my palm. White mist drifts across black water. Far away, stars shine with knife-edge clarity.

  The boat moves without sound, cutting through an ocean that shouldn’t exist.

  A shoreline emerges.

  White land. Endless ice.

  I step down the ramp and my boots crunch on something hard. The air is thin and sharp. Gravity feels wrong—lighter. My body wants to bounce.

  I take another step, then another, and suddenly I’m half-running, half-floating, stupidly exhilarated.

  This is the edge of the Solar System.

  Izanami.

  When I think the name, the wind answers, whispering across the plain.

  It’s breathtaking.

  The horizon curves closer than Earth’s, like I’m standing on a small ball of frozen time. The sky is a deep, absolute black, littered with stars so bright they look artificial. A band of the galaxy cuts diagonally across it.

  Ice crystals drift through the air, catching starlight and splitting it into faint rainbows. They fall slowly, lazily, as if the world is underwater.

  In the distance, a forest of massive ice spires rises like glass trees. Beyond that, a canyon of snow opens its mouth, shadows too deep to be natural.

  And then I see the probe.

  A lonely machine, antenna angled toward a sky that will never answer in time.

  Beside it—

  She’s there.

  Mii stands on the ice in clothes I remember from years ago. Her hair moves in the wind, picking up starlight like it’s its own kind of thread.

  My voice fails.

  When it finally comes out, it’s small. “Hey. It’s been a while.”

  She smiles like she’s been waiting. “So you saw it.”

  “Yeah.” My throat tightens. “Why?”

  She tilts her head, thoughtful. “Maybe… your feelings and mine synchronized.”

  I give a broken laugh. “That would be just like us. Even when we fought.”

  Tears blur my vision. The plain stretches endlessly, pure white.

  Mii looks up at the sky. “It’s lonely here,” she says, “but it’s not bad. I’ll rest a little… then I’ll go on.”

  “Go where?”

  “Beyond the dark river.” Her voice is calm, clear. “You’ll come too, someday.”

  The words settle into me like a stone.

  I step toward her, reach out.

  Before my fingers can touch, the wind surges. Ice crystals whirl up, turning the world into white noise.

  “Mii!” I shout.

  My voice dissolves into the mist.

  Through the storm I see her smile, unchanged, as she drifts away from me like a figure underwater.

  “See you again,” she says.

  Then she’s gone.

  I wake to a hotel ceiling.

  My cheeks are wet. Tears have dried into salt. I sit up slowly, like my body is unfamiliar.

  In the mirror, my face looks the same.

  But my eyes don’t.

  The morning sky is painfully clear. Mountains in the distance glitter with snow.

  I think: maybe the dark river exists.

  Maybe Mii has already crossed it.

  And maybe—somewhere beyond the edge of our maps—she’s waiting.

  I check out.

  I return to my city, to my classes, to the life I’ve been half-living.

  But something inside me has started to move again.

  My phone buzzes.

  A news alert, timestamped seconds ago:

  NEW IMAGE DOWNLINKED FROM IZANAMI LANDER.
