Prison, Ren was discovering, had its own version of education.
No classrooms.
No books.
No one standing at the front of a room waiting to be listened to.
Just people — people who had spent years learning things Ren had never bothered to understand, doling it out in the spaces between chores, on their own terms, when they judged you’d earned it.
Jiro had taught him the first lesson without ever calling it a lesson: adapt.
Hanako, he suspected, was about to teach him the second.
He went to find her deliberately this time — not because his wound needed rewrapping, but because he wanted to.
She didn’t look surprised to see him without a bandage-related excuse.
If anything, she looked like she’d been waiting to see how long it would take.
He’d noticed something on the walk over, the kind of small detail he was only just starting to catch now that he’d stopped simply surviving this place and started actually looking at it: a guard posted outside the infirmary door who wasn’t posted anywhere else on this side of the block, present but not close enough to hear anything said inside.
“Why is there a guard on your door and not mine?” he asked, before he’d fully decided to ask it.
Hanako didn’t look up from the containers she was arranging.
“Because I’m not housed on this side.”
“Where are you housed, then?”
“Somewhere with a different wall around it.” She set the last container down with a small, precise click.
“Women don’t share blocks with men in this prison.
I get brought across for infirmary hours, under escort, because there’s no doctor and someone has to be one badly enough that the rule bends for it.
It doesn’t bend far.”
“So you can’t just—”
“Wander wherever my curiosity takes me?
No.” A dry note crept into her voice.
“I have a schedule.
I have a guard.
I have exactly as much freedom as this prison’s medical problem is worth to them, and not one inch more.”
“That’s…” He searched for the right word.
“Efficient.
In a bleak sort of way.”
“Everything here is efficient in a bleak sort of way.
You’ll get used to the phrase.”
He filed that away with everything else he was learning to file away lately — one more piece of the shape of this place, one more reminder that even the people who seemed to move through it freely were bound by rules he simply hadn’t learned to see yet.
She set six small containers on the table between them.
“What’s in them?”
“Herbs.”
“I’d figured that part out.”
She gave him a look.
He decided not to push his luck.
“Sorry.”
She tapped the first container.
“This?”
He picked it up, turned it over, smelled it.
“Something bitter.”
“That’s not an answer.”
“I know.”
“Then don’t guess.”
He set it down.
She tapped the second.
“And this?”
“…Different smell.”
She sighed, the particular sigh of someone recalibrating their expectations downward.
“You know nothing.”
“That’s why I’m here.”
“You’re here because you were imprisoned.”
“That too.”
She looked at him for a moment, and then — unexpectedly — smiled.
“You really do talk too much.”
“I’ve been told.”
Hanako taught differently than Jiro did.
Jiro taught through repetition, the same motion a hundred times until the body stopped arguing with it.
Hanako taught through questions, and she had an infuriating habit of never accepting an answer that was only almost correct.
Ren had expected pharmacy to be something like memorization — this plant equals this cure — and instead found himself being handed a much more uncomfortable idea: that the same leaf, depending on preparation and dosage and the person taking it and what else was already in their body, could be medicine, or nothing, or poison.
There was no fixed answer sitting inside the plant itself.
The plant didn’t know what it was going to be.
That depended entirely on the person holding it.
It reminded him, distantly, of chemistry — a subject from a life that felt increasingly like something he’d read about rather than lived.
No laboratory here.
No proper glassware, no modern reagents.
But the underlying rules hadn’t changed just because the world around him had.
Matter still behaved the way matter behaved.
That was a small, strange comfort: the universe hadn’t rewritten its fundamentals just to make his life harder.
“What’s this?” She handed him a dried leaf.
“Medicine?”
“Maybe.”
“Food?” New chapters come out on g.com first.
“Maybe.”
“Poison?”
“Maybe.”
He frowned.
“That’s incredibly unhelpful.”
“Exactly.”
She tapped it.
“You don’t identify medicine by appearance alone.
You need to know the plant.
The part used.
Preparation.
Concentration.
Dosage.
Method.
The patient.
What else they’re already taking.”
He nodded slowly along with each one, filing them like inventory.
“So medicine is basically chemistry with paperwork.”
She stared at him.
“Forget I said that.”
“I wish I could.”
Most of what his body was actually relearning that first stretch had nothing to do with a sword at all.
He fell more than he liked to admit — stepping wrong on uneven ground, reaching to catch himself with an arm that simply wasn’t there anymore and toppling instead — and it was Jiro, more than once, who barked a correction at him from across the yard before he’d even finished hitting the dirt.
“Roll it.
Don’t catch it.” “Get up faster than that.” “Both feet, not one.” None of it was framed as teaching.
It read more like a man who couldn’t stand watching something done badly and happened to be within shouting distance.
But Ren noticed his falls stopped hurting quite as much after a few weeks, and that getting back up had stopped being its own small crisis every single time, and he filed that away as its own kind of lesson even if nobody involved would have called it one.
In whatever time was left over after chores and lessons — and there wasn’t much of it — he still found his way to the edge of the yard most evenings, watching Jiro run through the same handful of forms over and over.
Jiro hadn’t agreed to teach him anything more than that.
Watching was still the entire deal.
Ren was starting to suspect he was memorizing the shapes anyway, whether Jiro meant to be teaching him or not.
The lessons turned serious when she moved on to first aid.
Ren already had some of this — fragments from a life before this one, pressure on wounds, keep it clean, watch for shock — but he learned quickly that knowing something and being trusted to do it under someone’s actual bleeding hand were not the same skill.
She handed him a strip of cloth.
“Bandage this.” A practice dummy, arm outstretched, patient in the way only something without nerves could be.
He pinned one end under his thumb and tried to wrap it the way he’d have wrapped anything, before — both hands moving together, one feeding, one turning.
Except there was no second hand to feed it.
The cloth kept slipping loose the moment he let go to reach for more, and by the third attempt he was holding the end down with his chin, which was undignified and, worse, not working.
“Use your teeth,” Hanako said, not looking up.
“Or your knee.
Or the table edge.
Whatever’s free.”
He tried the table edge — pinned the tail of the cloth under it, wrapped one-handed, pulled it taut against the fixed point instead of a second hand.
It was slower.
It held.
“Too loose.”
He tightened it.
“Too tight.”
He adjusted.
“Again.”
He did it again.
And again, and again, until his fingers ached in a way that had nothing to do with the shoulder, and he finally groaned out loud.
“You’re enjoying this.”
“Yes.”
“At least you’re honest.”
She walked him through infection, fever, the different textures of pain, dehydration, burns — how to stabilize someone until a real healer could be found, which in this prison, he was starting to understand, might simply mean her, on a bad day.
She taught him what not to do with the same weight she gave everything else, maybe more.
Never assume something is harmless because you don’t recognize it.
Never use an unknown substance on an open wound.
Never mix medicines without knowing what they do.
Never assume more medicine means faster recovery.
Never treat the patient you wish you had.
Treat the patient in front of you.
He memorized all of it.
Some lessons announced themselves as important.
These didn’t need to — he could feel, somehow, that they were the kind of sentence that would matter again later, in circumstances he couldn’t yet picture.
One afternoon she brought him along to the infirmary itself.
A prisoner had opened two fingers badly on something in the workshop; the man was pale in a way Ren had started to recognize as a warning sign rather than just a color.
Ren stood at her side.
“What do I do?”
“Tell me.”
“Stop the bleeding.”
“How?”
“Pressure.”
“Then?”
“Clean it.”
“With?”
“Clean water.”
“Then?”
“Check for deeper damage.”
“How?”
He hesitated.
“Carefully.”
“Good.”
He helped her work.
His hand wasn’t entirely steady.
She noticed — she noticed everything, he was beginning to understand, and simply chose which things to mention.
“You afraid?”
“Yes.”
“Good.”
He looked up at that.
“Good?”
“Fear reminds you that you’re holding someone else’s life.”
He turned that over for the rest of the day, and kept turning it over long after.
Medicine, it turned out, wasn’t about the absence of fear.
It was about staying careful inside it.
The prison didn’t get safer after that.
It got more legible — corridors that mattered, patterns worth noticing, the particular ordinariness of a place once you’d been inside it long enough to stop flinching at every sound.
He still wasn’t thinking seriously about escape.
He was six years old with one arm, no weapon, no one he could yet call an ally in any way that mattered, and an incomplete map of a building he’d been dragged into unconscious of its layout.
He had already paid, expensively, to learn the difference between courage and simply not knowing better.
He intended to keep that lesson filed close.
Eventually Hanako introduced a new subject, and it was obvious from the moment she said the word that this was the one Ren had been quietly hoping for.
“Poisons.”
He tried very hard not to look interested.
“Don’t look so excited.”
“I wasn’t.”
“You were.”
“I was curious.”
“That’s worse.”
She set out several sealed containers, and something in her manner shifted — not warmer, exactly, but more deliberate, like she was handing him something with real weight.
“Poison isn’t simply something that kills.” She went down the list without hurrying.
“Some disable.
Some induce sleep.
Some cause vomiting.
Some affect the heart, or the nervous system, or produce symptoms that only resemble illness.”
His expression sobered without him quite deciding it should.
“And some can be used as medicine.”
“Exactly.”
He looked at the containers a long moment.
It was the same lesson as the herbs, just sharpened — a substance had no fixed moral character sitting inside it.
What it became depended on quantity, and purpose, and the hand doing the measuring.
That felt like it was true of more things than medicine, though he didn’t say so out loud yet.
“Can you make antidotes?”
“Sometimes.”
“To everything?”
“No.”
“Can you identify every poison?”
“No.”
He smiled.
“Good.”
She frowned.
“Why is that good?”
“Because if you knew everything, I couldn’t learn anything from you.”
She looked at him for a moment — the way she looked at a wound before deciding how to treat it — and then, quietly, she laughed.
“Start memorizing,” she said, nodding at the shelf.
“How many?”
“All of them.”
He looked at the rows stretching past her — easily hundreds — and laughed too, short and real.
“Okay.”
He rolled his shoulder.
“Let’s begin.”
