The sea didn’t always take with teeth.

  Sometimes it took with silence.

  Sometimes it took with fog that erased distance and made radar lie.

  Sometimes it took with one clean torpedo wake in the wrong place.

  Sometimes it took with the simple math of being sent somewhere you should never have been sent at all.

  Tōkaidō remembered many sorties.

  She could list them like numbers if she wanted. Operation codes. Escort routes. Coastal defense runs. Search-and-destroy sweeps through reef corridors. Night engagements where the water glowed faintly from burning fuel and dying fairies.

  She remembered the smell of hot metal and the taste of salt in her mouth when her guns fired for long periods and the recoil shook her bones.

  She remembered how the sea sounded when it was calm for too long.

  She remembered screaming.

  And she remembered the way people called it “necessary.”

  But there was one mission that didn’t sit in her mind like a normal scar.

  It sat like a missing limb.

  Because it hadn’t just taken ships.

  It had taken her sisters.

  It began as an honor.

  That was how they framed it.

  Five Yamato-class units assigned to contested waters. A show of strength. A morale statement. A deterrent. A “demonstration” to remind the Abyss that humanity still had gods of steel.

  They made it sound like strategy.

  Tōkaidō learned later it had been desperation.

  A fortress chain had been hit repeatedly in a narrow corridor—one of those ugly no-man’s routes where shipping lanes curved between drowned wreckfields and abyssal-infested trench edges. The Abyss had started using that corridor to raid convoys and isolate patrol detachments. The Admiralty wanted to hammer it flat before it became an open wound.

  So they reached for the biggest hammer.

  Five Yamato-class.

  Not all true originals—some new-wave like Tōkaidō, some older, some tuned differently by hull resonance. But all of them carrying that name that made people speak softly.

  Tōkaidō remembered the briefing room.

  A large table. Maps. Red markers. Arrow lines.

  Human officers talking like they were moving pieces on a board rather than sending living beings into water that wanted them dead.

  The Commander’s voice had been calm, almost reverent.

  “This is a priority operation,” he’d said. “You will not fail.”

  He’d looked at them one by one.

  Some of her sisters looked proud, eager to prove themselves.

  One looked annoyed.

  One looked tense.

  One looked… too quiet.

  Tōkaidō had kept her hands folded and her voice soft.

  “Yes, Commander,” she’d said, because that was what you did.

  And because she still believed—back then—that if she performed perfectly, the world would treat her with something resembling respect.

  They left at dusk.

  They always left at dusk for contested waters.

  Because night made it easier to hide.

  And harder to survive.

  The first hours were uneventful.

  Too uneventful.

  The ocean lay flat, dark, a mirror that didn’t reflect stars properly because the clouds were low and heavy.

  The fog rolled in before midnight.

  Not normal fog.

  Not coastal mist.

  This fog had weight.

  It clung to radar returns and made the screen smear. It swallowed sound. It turned distance into guesswork.

  Tōkaidō remembered the moment the first sonar ping came back wrong.

  The cadence wasn’t right.

  It didn’t match known Abyssal destroyers or cruisers.

  It was deeper.

  Larger.

  And it moved like it wasn’t obeying water resistance.

  Her sister on the comm line—one of the older Yamatos—had spoken first.

  “Hold formation,” she’d ordered.

  Then the sea erupted.

  Abyssals did not rise like ships.

  They rose like nightmares deciding to be real.

  Hull silhouettes tore through fog, their outlines jagged, wrong, decks overcrowded with mismatched guns, smoke pouring from funnels like black breath.

  There were too many.

  And then—behind them, deeper, a heavier shadow.

  A battleship-class Abyssal, perhaps two, their gun reports sounding like thunder in a sealed room.

  The first salvo hit one of her sisters before anyone could react.

  Not because her sister was weak.

  Because the enemy had been waiting.

  The shell struck the waterline.

  Metal screamed.

  A Yamato-class hull—one of the new-wave—shuddered, smoke rising.

  Tōkaidō’s breath caught.

  She remembered firing.

  All of them fired.

  Five Yamato-class opened up in the fog, their guns lighting the world in brutal orange flashes.

  The sea became a strobe of violence.

  And for a few minutes, it almost worked.

  Their shells tore abyssal cruisers apart. Destroyers vanished in sprays of steel and water. The fog glowed with fire.

  Tōkaidō heard one of her sisters laugh over the comms.

  Not joy.

  Pure battle-high madness.

  Then the torpedoes came.

  Abyssal torpedo wakes were not clean white lines like human ones.

  They were black streaks.

  Oil-slick and wrong, as if the water itself had been stained by the weapon’s intent.

  Tōkaidō dodged the first spread by instinct, her shipform sliding, engines pushing hard.

  Another sister was not as lucky.

  A torpedo struck her amidships.

  Then another.

  Then another.

  Three hits in under ten seconds.

  The comm line filled with static and a choked gasp.

  A Yamato-class voice—high, shocked—saying:

  “Wait—no—”

  Then silence.

  Just… silence.

  One sister down.

  Tōkaidō’s hands trembled on her fire control.

  She kept firing anyway.

  Another sister took a direct main battery hit.

  The shell punched through armor and exploded inside.

  The sound over comms was not a scream.

  It was a noise—a raw, strangled sound of someone realizing their body was being turned into scrap.

  Did you know this story is from Royal Road? Read the official version for free and support the author.

  Then the voice cut out mid-word.

  Two down.

  The third sister tried to hold the line.

  She was the proud one.

  The fiery one.

  She called targets and kept formation, refusing to break even when the fog swallowed her escort ships like ghosts.

  Tōkaidō heard her voice, clear and furious.

  “Do not run. We are Yamato-class. We do not—”

  A heavy abyssal battleship silhouette surfaced close—too close, like it had crawled under the fog and risen inside their formation.

  Its guns fired point-blank.

  The sister’s transmission cut into static.

  When it returned, it was weak.

  “…I…” she whispered. “…can’t…”

  Then nothing.

  Three down.

  Tōkaidō couldn’t even process it.

  Her mind tried to treat it like numbers.

  One. Two. Three.

  But they were names.

  Faces.

  Voices.

  Sisters.

  The fourth sister—the too-quiet one—had been taking hits already, her hull trailing smoke, her secondary batteries silent.

  She didn’t say much on comms.

  She never did.

  But now she spoke, voice low, almost calm.

  “Tōkaidō,” she said.

  Tōkaidō’s throat tightened.

  “Yes?”

  The sister’s voice was faint.

  “…Go.”

  Tōkaidō froze.

  “What?”

  “…Go,” the sister repeated. “Someone must come back. Someone must remember.”

  Tōkaidō’s stomach twisted.

  “I can—”

  The sister cut her off softly.

  “No,” she said. “You cannot save everyone. That is a human fantasy. Go.”

  Then the sister’s transmission filled with a sudden roar—guns firing, a reckless charge, her hull pushing forward into the abyssal mass like a sacrificial blade.

  Tōkaidō heard impact noises.

  Metal tearing.

  The sister’s calm voice, one last time:

  “Live.”

  Then silence.

  Four down.

  Only Tōkaidō remained.

  Only her.

  In the fog.

  In the rain of shell fragments.

  In the black water.

  The mission was already lost.

  Not because they hadn’t fought.

  Not because they lacked firepower.

  Because they’d been thrown into contested waters like a statement, and the sea had answered with teeth.

  Tōkaidō’s shipform took a hit—glancing, not fatal—but enough to rattle her bones and make her vision blur with pain.

  Her instincts screamed at her to retreat.

  Her pride screamed at her to stay.

  Her grief screamed at her to die with them.

  But her sister’s voice—Live—cut through it all like a blade.

  So Tōkaidō did what she hated.

  She ran.

  Not a panicked retreat.

  A controlled withdrawal.

  Smoke deployed.

  Course changed.

  Speed pushed.

  She fired as she withdrew—covering her own escape, her guns punching holes in the fog, carving a path through abyssal pursuit.

  A destroyer tried to close.

  She erased it with a full broadside.

  A cruiser followed.

  She crippled it enough to slow it, then vanished into the fog like a ghost.

  It took hours.

  The fog clung and followed, as if the sea wanted to keep her.

  But eventually, the abyssal sonar pings faded.

  Eventually, the horizon lightened.

  Eventually, she found herself alone in grey dawn, the sea quiet again like nothing had happened.

  Tōkaidō stared at the empty water.

  No wreckage visible.

  No bodies.

  Just the ocean pretending.

  She didn’t cry.

  Not then.

  Her grief was too heavy to be tears.

  It sat behind her ribs like a stone.

  They called her a survivor.

  Humans always called survivors something, as if naming it made it mean less.

  In the debrief, they asked questions like it was an investigation rather than a funeral.

  “How many contacts.”

  “What was the composition.”

  “Were there anomalies.”

  “Could you have held longer.”

  “Why did you retreat.”

  Why.

  As if retreating had been a moral failure.

  Tōkaidō sat in the debrief room with her hands folded and her voice soft.

  She answered calmly.

  Yes, Commander.

  No, Commander.

  Unknown, Commander.

  She did not tell them about her sister’s last words.

  Because humans would turn “Live” into doctrine.

  They would weaponize it.

  She kept that word for herself.

  In the weeks after, she expected punishment.

  Survivors were inconvenient.

  Survivors reminded people that plans failed.

  Sometimes the Admiralty rewarded survivors with praise.

  Sometimes they blamed them.

  Tōkaidō learned quickly that praise and blame were both dangerous forms of attention.

  Instead of collapsing into guilt, she did what she had always done.

  She adapted.

  She became quieter.

  More polite.

  More careful.

  She let the humans believe she had been shaken into obedience by the loss, because that was what they expected.

  Inside, grief burned.

  But she did not let it consume her.

  She made it into something useful.

  Not rage.

  Not self-destruction.

  Purpose.

  Around that time, she learned a rumor that became a hook in her mind.

  Amagi was at Horizon.

  Abandoned.

  Sent away like a failing machine because her condition was inconvenient.

  Tōkaidō remembered the corridor.

  The gentle voice.

  Stay well.

  And she felt something cold and sharp settle into her bones.

  If Amagi was abandoned there…

  Then Horizon was not just a dumping ground.

  It was where the world threw away people it didn’t want to deal with.

  Tōkaidō understood that.

  She had just watched the world throw away her sisters.

  So she decided, quietly, that she would go.

  Not because she wanted to hide.

  Because she wanted to choose.

  But choosing openly was dangerous.

  So she did it the way she had learned to survive:

  She made the humans think it was their idea.

  Her Commander at the time wasn’t the worst kind.

  He wasn’t sadistic.

  He wasn’t openly cruel in the way some commanders were.

  But he still treated KANSEN like equipment.

  He spoke of them in terms of deployment value.

  He rewarded obedience.

  He punished inconvenience.

  He was stern. Efficient. Pragmatic.

  The kind of man who would pet a dog and then send it into a minefield without blinking.

  Tōkaidō studied him.

  Carefully.

  Quietly.

  She learned what he wanted to hear.

  She learned how to present herself as a “problem” without becoming a real problem.

  She started making small mistakes.

  Not catastrophic.

  Not insubordinate.

  Just… inefficient.

  A delayed response here.

  A hesitant call there.

  A quiet refusal to volunteer for glory missions.

  She let her nervousness show more.

  She let her soft voice become a “lack of presence” in his eyes.

  She became, on paper, less valuable for frontline leadership.

  And then she began to talk—subtly—about Horizon.

  Not about Amagi.

  Never about Amagi.

  She framed Horizon as an inconvenience posting, a place where “assets” were dumped.

  She asked questions like she didn’t care but was simply curious.

  “Commander,” she said one day, voice soft, “is it true Horizon is only used for repair overflow?”

  He grunted.

  “Yes.”

  Tōkaidō nodded.

  “It sounds… quiet,” she murmured.

  He glanced at her.

  “What.”

  Tōkaidō lowered her gaze.

  “After the last operation,” she said softly, “I may not be… ideal for contested waters.”

  She let the implication sit.

  Not “I’m afraid.”

  Not “I’m broken.”

  Just: I am inconvenient now.

  Her Commander’s eyes narrowed.

  He disliked inconvenient things.

  Tōkaidō continued, gentle and respectful.

  “Perhaps I could be more useful,” she offered, “as a deterrent presence at a lower priority base. I would still serve. I would still maintain readiness. But…” She hesitated slightly, letting vulnerability show. “…I would not risk another formation loss.”

  The Commander’s jaw flexed.

  He didn’t care about her feelings.

  But he cared about statistics.

  Another Yamato-class loss under his command would stain his record.

  And Tōkaidō, quietly, gave him a solution that sounded like it protected him.

  Horizon.

  He thought about it.

  She could see it in his eyes.

  Calculation.

  Not mercy.

  He nodded once.

  “I’ll consider reassignment,” he said.

  Tōkaidō bowed deeply.

  “Thank you, Commander.”

  Inside, her chest tightened with relief.

  She didn’t show it.

  She couldn’t.

  Because if he sensed she wanted it, he might deny it out of spite or suspicion.

  So she kept playing the role.

  Quiet.

  Nervous.

  Soft.

  A Yamato who had lost her edge.

  A Yamato who might be better used somewhere out of sight.

  Eventually, the paperwork came.

  Transfer to Horizon Atoll.

  Indefinite assignment.

  Tōkaidō read it with her hands trembling slightly.

  Not fear.

  Relief.

  She bowed to her Commander when he told her.

  He looked pleased with himself.

  “This is for the best,” he said.

  Tōkaidō lowered her gaze.

  “Yes, Commander.”

  He thought he’d decided it.

  That was the point.

  Horizon Atoll, fifteen months before Kade and Vestal arrived, was not the place it was now.

  It was smaller.

  Not in landmass—Horizon had always been huge compared to old Earth’s Wake.

  But smaller in spirit.

  It felt like a base that had already accepted it would eventually be swallowed.

  The docks were cracked.

  The repair facilities barely functional.

  The housing prefabs damp and crowded.

  The supply situation worse than “thin.”

  And the people—humans and KANSEN alike—carried a quiet resignation that made the air feel heavier than humidity.

  When Tōkaidō arrived, the roster was short.

  Iowa was there.

  Nagato was there.

  Asashio was there.

  Shoukaku was there.

  A small group.

  They weren’t social then.

  Not because they hated each other.

  Because Horizon didn’t feel like a place where you could afford closeness.

  Close attachments hurt more when people vanished.

  The Commander at the time…

  He was cruel.

  Not loud-cruel.

  Not theatrical.

  He didn’t need to shout much.

  His cruelty was systematic.

  Punishment disguised as discipline.

  Humiliation disguised as “correction.”

  If a girl made a mistake—even an accident—he made her pay.

  Not always physically, but in ways that cut deeper.

  Isolation.

  Deprivation.

  Public “inspection” that was really public shame.

  Forcing KANSEN into tasks that made them feel like machines.

  Tōkaidō did not like talking about it.

  Even now, sitting on her turret in the rain, she felt her stomach tighten remembering his voice.

  “You are assets,” he’d say, calm and cold. “Do not forget your purpose.”

  Some girls endured.

  Some broke.

  Some vanished.

  Sorties still happened.

  Horizon still sent patrols out, because the sea didn’t care that the base was neglected.

  And the mass-produced girls—especially the ones who looked too young, too childlike, too “cute” for war—were often the ones thrown into those missions.

  Dumped there because they were “difficult to manage.”

  Too childish.

  Too emotional.

  Too inconvenient for commanders who wanted clean obedience.

  They were treated like disposable mascots until they were treated like disposable weapons.

  Most didn’t come back.

  Tōkaidō watched it happen.

  Quietly.

  Her hands clenched under her sleeves more than once.

  She wanted to intervene.

  But she was new.

  And Yamato-class did not mean authority under treaty law.

  It meant you were valuable hardware.

  You could still be punished.

  Scrapped.

  Tuned.

  The only constant, strangely, was Gunnery Sergeant Hensley.

  Hensley was there.

  At first, he had been indifferent to Tōkaidō.

  He was indifferent to most things that weren’t his job.

  But there was one line in him that did not bend:

  he protected the kid-like mass-produced.

  Fiercely.

  Not with speeches.

  With presence.

  With the way he would appear at the right moment and stand between a cruel officer and a frightened DE girl with big eyes.

  With the way he would quietly reroute missions if he could.

  With the way he would glare at the Commander like he was daring him to try something.

  Hensley didn’t act like he cared.

  He acted like it was duty.

  But Tōkaidō saw it anyway.

  She saw how his hands would tighten when one of the childlike girls didn’t return.

  She saw how he would sit alone sometimes afterward, staring at the sea like he was trying to burn it.

  Tōkaidō never asked him about it.

  She didn’t need to.

  Some grief didn’t like being spoken.

  The first time Tōkaidō saw Amagi again at Horizon, it felt like the world tilted.

  Amagi was in a medical-adjacent space, half deconstructed, quiet, surrounded by repair scaffolding that looked more like a cage than care.

  Her eyes were tired.

  Her body looked too thin for the spirit inside it.

  But when she saw Tōkaidō, her expression softened.

  The same small, gentle smile.

  The same quiet grace.

  “Tōkaidō,” Amagi said softly, voice warm despite everything.

  Tōkaidō’s throat tightened.

  She bowed deeply, almost too deeply.

  “I came,” she whispered.

  Amagi’s gaze softened.

  “I see,” she said gently.

  Tōkaidō stepped forward and did what she knew how to do:

  she stayed.

  She adjusted blankets.

  She fetched tea.

  She guarded Amagi’s quiet.

  She became a steady presence in a base that did not offer steadiness.

  She did it without asking for recognition.

  Because she didn’t need recognition.

  She needed Amagi to not be alone.

  Fifteen months.

  That was how long it took between Tōkaidō arriving and Kade and Vestal landing at Horizon.

  In those fifteen months, the base changed slowly even before Kade—other ships arrived, some left, some died. The roster grew in fits. Girls like Atlanta appeared later. Others drifted in, seeking somewhere less suffocating than their previous commands.

  But the biggest change came with Kade.

  And Tōkaidō, walking down the dock from her shipform, could feel it like warmth under her ribs.

  Because before Kade, Horizon had been a dumping ground with a cruel man in charge.

  After Kade…

  It was still broken.

  Still under-supplied.

  Still vulnerable.

  But it was alive.

  It laughed.

  It ate together.

  It built.

  It argued.

  It defended its own.

  It stopped treating people as disposable.

  It started treating them as names.

  Tōkaidō thought of the dance again—just a flicker of memory, chandeliers and music and Kade’s hand offered like defiance wrapped in tenderness.

  Her cheeks warmed faintly.

  Arizona had called it glowing.

  Tōkaidō exhaled slowly and looked out over Horizon’s harbor.

  Cranes moved.

  Workers shouted.

  Marines carried crates.

  Vestal bullied people into health.

  Iowa probably plotted whiskey liberation.

  And somewhere inside the base, Amagi waited.

  Tōkaidō walked carefully, rain sliding from her sleeves as she moved through Horizon to go see Amagi.

  She didn’t linger on grief too long.

  She couldn’t.

  She carried her sisters with her, but she refused to let their loss become a chain.

  Instead, she turned that pain into purpose.

  She walked down the path from the harbor that headed towards the repair bay.

  Toward the gangway.

  Toward Amagi.

  Toward the strange new world Kade had begun to carve out of wet concrete and stubborn hearts.

  A lot had changed thanks to him.

  Tōkaidō didn’t know what the future would look like.

  But for the first time in a long time—

  she let herself believe it might be something worth surviving for.
