Ren didn’t remember deciding to sleep.
One moment he was sitting against the cold stone with his hand curled into a fist, telling himself he was still here, and the next the cell had dissolved into the training yard back home — except the light was wrong, and the air was wrong, and the sword was already coming down before he understood he’d gone anywhere at all.
He didn’t get to brace.
He never got to brace, not in the memory and not in whatever this was — the moment simply arrived, whole, and his arm was gone before his mind had caught up to the idea that it could be.
He heard himself scream.
He wasn’t sure, afterward, whether that part was memory or something his body had just done, out loud, in the dark.
His eyes snapped open.
Stone ceiling.
Prison cell.
Darkness.
He breathed.
One.
Two.
Three.
His heart didn’t listen to the counting.
It rarely did, he was learning — counting was a suggestion, not a command, and his body had apparently stopped taking suggestions from him somewhere around the moment the blade landed.
He lay still and let it happen anyway, because fighting it seemed to make it worse, and because some small, exhausted part of him had decided that surviving the fear was different from winning against it, and that surviving would have to be enough for tonight.
He looked toward his left shoulder — the bandages just visible in the thin moonlight through the tiny window — and stared at them until a word came out of him without his permission.
“Idiot.”
Jiro’s eye opened.
“What?”
Ren froze.
“Nothing.”
“You were talking.”
“I do that.”
“Stop.”
He turned away.
“Fine.”
A minute of silence.
Then, from the dark, in a voice that didn’t sound like it was offering comfort so much as stating a fact:
“You’ll get used to it.”
Ren looked over.
“To what?”
“The pain.”
He didn’t answer.
Jiro closed his eye again.
“The rest takes longer.”
Ren understood exactly what the rest meant.
He looked down at where his arm wasn’t, and hated that Jiro had said it out loud, and hated more that Jiro was probably right.
He lay awake a long time after that, not because of the nightmare this time, but because the rest takes longer was the kind of sentence that didn’t let you fall asleep comfortably.
It sat with you.
Morning came without sunlight.
A bell rang, and Ren woke immediately — the kind of waking that had nothing to do with rest.
Guards opened the cells.
Ren expected to be handed a broom.
Instead, the guard looked at his bandages, grunted something to a second guard, and jerked his head down the corridor.
“Infirmary first.
New arrivals with wounds get seen before work.”
Jiro didn’t look surprised.
He didn’t say anything either — just watched Ren go, the way he seemed to watch everything, filing it away for whatever purpose Jiro filed things away for.
The room smelled of vinegar and dried plants.
A woman was measuring something into a small dish and didn’t look up right away.
“Sit.”
Ren sat.
It was easier than arguing, and some instinct told him this particular person wasn’t going to be moved by his usual approach to authority.
She unwound the outer layer of his bandages without asking permission, hands quick and unbothered, and Ren watched her face for a reaction he didn’t get.
No wince.
No pity.
Just attention.
“Are you a doctor?”
“No.”
“Then why are you treating me?”
“Because the doctor isn’t here.”
That answered more than the words themselves did — it told him something about the whole shape of this place before he’d even seen the rest of it.
He filed it away too.
“What are you, then?”
“Pharmacist.”
“You know how to treat this?”
“Enough to know when I need someone else.”
Ren looked at her a little differently after that.
Not because the answer was reassuring — it wasn’t, particularly — but because it was honest in a way most adults hadn’t bothered being with him lately.
“Hanako,” she said, before he could ask.
“Ren.”
She didn’t respond to that the way people usually did — no comment on his age, no comment on the arm, no comment on anything except the wound in front of her.
She cleaned it.
She checked the color of the skin around it, the heat of it, pressed here and there and watched his face instead of asking if it hurt.
It hurt.
He didn’t say so.
“You’ll come back in three days,” she said, wrapping the fresh bandage tighter than the last person had.
“Define stupid.”
“You’ll find a way.
Most people do.”
He decided, on balance, that he liked her.
The guard collected him afterward and put him to work.
He learned quickly that this place wasn’t built around rehabilitation.
It was built around labor.
Every prisoner had a task — stone, wood, metal, cleaning, food, repairs.
Anything that could be pulled out of a body without killing it first was considered worth pulling.
Ren was handed a broom.
He looked at it, then at the guard.
“Seriously?”
“Move.”
He sighed.
“Fine.”
One-handed, the broom kept slipping out of rhythm with itself, sliding wrong, catching wrong, until he adjusted his grip and it slid a little less wrong.
By the end of the first hour his shoulder hurt.
By the end of the second, his back joined it.
By the end of the third, he had developed a genuine, personal hatred for the broom specifically, as though it had chosen to make things difficult on purpose.
At lunch he sat beside Jiro.
The meal was a thin soup with rice, and Ren stared into it like it might improve under observation.
“Do they feed us this every day?”
“Usually.”
“That’s depressing.”
“Eat.”
He ate.
Fast.
Jiro noticed.
“You were hungry.”
“I’m always hungry.”
“You’re growing.”
Ren looked down at his six-year-old body, small and rearranged and still, somehow, expected to get bigger.
“I hope so.”
Jiro said nothing, and Ren sat with how strange that sounded.
Growing.
He’d once imagined it as something automatic — a thing that happened quietly while he trained, a background process he didn’t have to think about.
Now he understood how much had actually changed.
His body had lost something it would never get back on its own.
Whatever he grew into, he was going to have to grow around the missing piece, not through it.
That thought frightened him.
He didn’t let it decide anything for him.
Not anymore.
The first week taught him rules.
Don’t fight the guards.
Don’t steal.
Don’t wander into restricted ground.
Don’t touch what isn’t yours.
Don’t step into a fight that isn’t yours either, unless you wanted it to become yours.
Don’t complain about the food.
That last one seemed unreasonable.
He complained anyway — quietly, mostly to himself, which he decided counted as compliance in spirit if not in letter.
He also learned the shape of the place.
Some prisoners were dangerous.
Some were only loud.
Some were cowards, some were kind despite everything, and some he simply couldn’t read yet, which bothered him more than the dangerous ones did.
And some were watching him.
They weren’t interested in his crime.
They were interested in his age — a six-year-old in prison was strange enough on its own.
A six-year-old missing an arm made it stranger.
A six-year-old who watched everything back made people curious, and Ren had already learned, the hard way, exactly how expensive curiosity could get.
So he watched back.
He went back to Hanako on the third day, as told, and again after that.
It became a small fixture of the week — not a lesson, not yet, just the unwinding and rewinding of bandages while she asked short questions and he gave short answers.
“Fever?”
“No.”
“Sleeping?”
“Some.”
She looked at him for a beat longer than the question required.
“That’s not an answer.”
“It’s the honest one.”
The third visit was the one that mattered.
She caught him trying to sit up too fast, reaching across his body with a hand that had planned to hook something with an elbow that no longer existed.
He overbalanced.
She caught his good shoulder before he tipped off the table.
“You’re going to hurt yourself.”
“I’m already hurt.”
“That’s why I’m telling you.”
He didn’t have a clever answer for that one.
She didn’t seem to need him to have one — she just kept working, unbothered, the way she’d been unbothered by everything else about him so far, and something in Ren settled slightly at being handled like a problem to be managed rather than a tragedy to be pitied.
“You keep reaching for it,” she said, not looking up.
“I know.
That’s not a criticism.” She tied off the bandage.
“It’ll stop.
Eventually.
Not soon.”
“How do you know?”
“Because I’ve watched it stop before.”
Ren didn’t ask who.
There was a whole category of question, he was learning, that people here would answer eventually, on their own schedule, and not one second sooner for being asked.
His first real conversation with Jiro that wasn’t about pain or blankets happened on the ninth day, over a bucket.
Ren was trying to carry it one-handed.
He dropped it.
Water went everywhere, the guard shouted, and Ren apologized and cleaned it up while Jiro watched from a few feet away, unhelpful and unbothered.
“You keep trying to do things the old way.”
Ren looked up.
“What?”
“With two hands.”
He looked down — at the bucket, at his right hand, at the empty space where the other one used to help.
“Oh.”
Jiro stood, took the bucket, and showed him how to hook the handle against his forearm and lift with his shoulder and torso instead of his grip.
Ren tried it.
It worked.
His eyes widened.
“That’s clever.”
Jiro shrugged.
“You adapt.”
“How long did it take you to learn that?”
Something closed over Jiro’s face — not hostile, just private.
“A while.”
Ren nodded and tried again.
The bucket rose.
Not gracefully.
But it rose, and he found he was smiling.
“Thanks.”
“Don’t thank me.”
“Why?”
“You’ll learn eventually.”
“You’re saying prison is basically one giant tutorial.”
Jiro just stared at him.
“Never mind.”
A few days after that, Ren found Jiro training alone in a corner of the yard — no partner, no wooden sword drawn against him, just forms run against empty air, slow and exact.
Ren stopped to watch.
He didn’t say anything at first.
Neither did Jiro, though Jiro was plainly aware he had an audience.
Ren came back the next day, and watched again.
And the day after.
On the fourth day, Jiro finally spoke without breaking his form.
“You want something?”
“You’re a swordsman.”
“Yes.”
“Can you teach me?”
Jiro’s eyes went to the empty sleeve, then to Ren’s remaining hand, and he didn’t answer right away — which was, Ren was starting to notice, usually a worse sign from Jiro than an outright no.
“No.”
“Why?”
“You’re missing an arm.”
“I noticed.” The sarcasm didn’t land; Jiro didn’t so much as blink at it.
“That’s not something I can fix by tomorrow.
Neither can you.”
Ren’s jaw tightened, but he didn’t push it.
Something about the way Jiro said it — flat, not unkind, just final — told him this wasn’t a door that opened by knocking harder.
“Fine,” Ren said.
“Can I watch, at least?”
Jiro considered that for a moment longer than the question seemed to need.
“That, I don’t own.”
It wasn’t a yes.
It wasn’t a no either.
Ren decided to treat it as permission and sat down at the edge of the yard, and Jiro went back to his forms without another word, and that — for now — was the whole lesson: watching, and being allowed to.
Ren came back the day after.
And the one after that.
The prison, over those first weeks, stopped being only stone and rust and started becoming something with edges he could learn — corridors that were busy and corridors that weren’t, guards who shouted because they meant it and guards who shouted because it was required of them, prisoners worth a wide berth and prisoners worth a second look.
None of it added up to a plan yet.
He was six years old, one-armed, unarmed in every sense that mattered, and he had already learned — the expensive way — the difference between courage and simply not knowing better.
But he was watching.
Cataloguing.
Filing things away next to the small honest things people had told him without meaning to: that the doctor wasn’t here and Hanako was; that Jiro didn’t hand out lessons on request, only on evidence; that showing up, apparently, counted for more in this place than asking did.
He had come into the Iron Cell thinking he’d lost his future.
He was starting to suspect he’d actually lost something else — the certainty that used to sit underneath everything he did, the quiet assumption that he understood how things worked before he’d bothered to check.
Losing it hurt more than the arm did, some nights.
But he was beginning, just barely, to wonder if that particular loss was one he’d needed to survive.
He rolled his shoulder — just the one, now — and went back to watching Jiro finish his forms.
