The door under the water dropped them onto stairs without caring who landed first.
Ty hit the stone shoulder first. The impact snapped through his ribs and scraped sparks from both sickles. Water poured after him, dragging receipt scraps, painted paper mouths, and one collector hand that kept crawling until JJ’s boot crushed two fingers by accident.
JJ landed across his back and knocked what little air his body bothered keeping out of him.
"My ribs object to every decision that brought us here."
"You jumped into the flooded murder tunnel after me."
"You jumped first, which makes you the bad example."
"I am made of bones and poor judgment."
"That still fails as a permission slip for everyone else."
Omina came through the water door next and landed standing, because generals apparently trained for humiliating entrances. Yun-Jin came with her, teeth clenched, one hand pressed hard against her side. Heissman arrived last, rolled down three steps, and stopped with his sword arm over his face.
"I resign from any building that thinks stairs need opinions."
The water door slammed shut above them and took the sound of pursuit with it.
Silence took the space where the crowd had been. No cart bell. No collectors. No betting roar leaking through cracked stone. Only stairs, narrow and gray, climbing into the sealed water door and descending into a dark that felt counted before anyone stepped into it.
Numbers had been carved into every step, each one filled with old gray grit.
The first three waited above them like counted teeth.
JJ pushed herself off Ty and looked down the run.
"Please tell me this is the Name Office pretending to be ugly."
Omina studied the numbers with the expression of a woman recognizing paperwork on a battlefield.
"This is not the Name Office, and pretending will make it worse."
Heissman sat up slowly, checking his sword arm before his dignity.
"It is a punishment stair, or someone copied the academy’s worst idea."
Yun-Jin wiped water from her mouth and kept pressure on her side.
"Why does an academy need stairs for punishment at all?"
"Because the academy believed pain counted as curriculum."
"That explains more about you than I wanted before lunch."
Ty stood. The mark under his left eye socket pulsed white, and step nine answered with a wet shine across its carved number.
JJ saw it and pointed with her wrist panel.
"Nobody touches the ninth step until someone explains why it likes him."
Heissman laughed without finding anything funny in the sound.
"There is always a ninth step in institutions that enjoy billing children."
Omina’s silence confirmed the problem before her words did.
"Every ninth step tests payment from whoever crosses its reach."
"What does it decide we still owe exactly?"
"Whatever the lane can collect without feeling embarrassed."
Ty looked down the stair. Nine waited six steps below, ordinary except for the shine over the number and the way his empty memory pulled toward it.
"Then I go first and let it complain at me."
JJ, Yun-Jin, and Omina spoke over each other with the same answer, all of it meaning Ty had volunteered enough pieces already.
Heissman lifted one hand from the floor like a man voting from a ditch.
"I would like my emotional inclusion entered into the record."
Ty almost laughed. The sound hit the missing memory and failed there. Jade on a rainy street should have been somewhere inside him. The toll had taken it clean enough to leave only a bruise shaped like her absence.
JJ saw the change and lowered her voice.
"The last toll took something that still hurts when you reach for it."
"I remember paying, and that is all it left me."
"That is a cruel kind of accounting even for this place."
"This place keeps a theme better than most kings."
Omina stepped down to the fourth stair and tested the stone with her weight.
"We move in order. No rushing, no hero charges, and no letting pain choose the route."
Ty stared at her because anger needed somewhere to stand.
"Other people are being hunted while we discuss manners."
"Then we survive fast without making the stair richer."
That was true. He hated true things when they helped someone else win an argument.
They descended through five, six, and seven with the walls tightening around each breath.
The walls tightened as they moved. Ty kept his sickles close, but the tips still scraped stone when the stair narrowed around his elbows.
Eight waited close enough to make step nine feel hungry.
Step nine caught Heissman’s shadow before any foot reached it.
The shadow stretched wrong along the wall, thin and tall, wearing an academy uniform with silver cuffs. Three older shadows stood around it with clean boots and bored shoulders.
"Show us how a second lieutenant begs when the family account goes empty."
Heissman’s real body froze on step eight. The half sword shook in his hand. The academy shadow lifted its chin as if the memory still outranked him.
Yun-Jin moved first because pain had never made her patient.
Omina caught her by the back of the collar.
"Touch the ninth step and the stair starts billing you too."
"He is trapped in there with boys still kicking him."
"Yes, and the stair wants everyone to call rescue a purchase."
Ty lifted a sickle before the wall finished writing its threat.
The wall beside him scratched words into wet stone. Outside violence would be accepted as group debt.
JJ grabbed his wrist before the blade moved.
"If you swing, the stair charges everyone standing near you."
Heissman’s breath came through his teeth. One of the shadow boys kicked his shadow in the ribs, and the real Heissman folded by the same amount.
"This is old enough to stop pretending it owns me."
His voice had gone calm in the way that made rescue feel late.
The stair answered in a child’s voice, calling the debt disputed.
Heissman lifted his head, and rain from the memory ran through his hair.
"Of course the bill learned how to whine."
He stepped onto nine before fear found a smarter argument.
Omina cursed, but the old scene took him before anyone could pull him back. The shadows became bodies. Damp academy stone replaced the stair wall. Rain hammered high windows. A younger Heissman knelt in a training yard with a wooden sword broken beside him.
Three older cadets stood around him with boots clean enough to feel expensive.
JJ saw all of it from the edge of somebody else’s wound.
The lead cadet held a ledger in both hands like scripture.
"Your father’s payment failed, and that makes you the lesson today."
Young Heissman wiped blood from his mouth onto the back of his wrist.
"Then bill him properly and stop wasting my afternoon."
"We did, and he sold your mother’s ring before breakfast."
The real Heissman shook. Ty’s grip tightened around the sickle haft until bone scraped metal.
Yun-Jin’s voice cut through the memory with more force than breath.
"Heissman, answer me before this place decides silence is consent."
Her voice missed him and broke against the rain.
The lead cadet dropped the ledger in the mud.
"Pick it up with your teeth and thank the academy."
Young Heissman looked at the ledger. Then at the cadet. Then he smiled with a mouth full of blood.
"Read the balance first. I like knowing what I am biting."
The memory faltered around the edges of the ledger.
The real Heissman laughed once, ugly and honest enough to break the old rhythm.
"I was always charming under poor supervision, apparently."
He drove the half sword into the ledger.
Step nine cracked down the middle. The wall acknowledged the debt, refused shame as payment, and moved the interest down the stair.
JJ’s wrist panel flashed pink before the stair answered her question.
"Transferred where, and why do I already hate the answer?"
Step eighteen lit beneath Yun-Jin’s foot with the color of old blame.
She went rigid. Omina pulled her back, but the stair had already opened around them. Pink light filled the walls. Smoke pushed under a childhood door, and a smaller Yun-Jin stood inside with an arrow clutched in both hands.
Outside the room, two silhouettes knelt in royal chains.
Ty’s fire went cold along the inside of his ribs.
Yun-Jin’s denial came out too thin to carry her.
Omina’s grip failed, and the stair took both women at once.
Step twenty-seven below them split open, and a door appeared with the Name Office seal burned into the wood. The door began closing before the first breath of relief reached anyone.
JJ looked from the door to Yun-Jin’s memory and understood why the stair had waited to make them choose.
Ty already knew the shape of the cruelty. The route was closing while Yun-Jin burned in old smoke.
Omina made the choice before he could spend himself on it.
She stepped fully into Yun-Jin’s memory and shoved the younger girl away from the smoke. The Name Office door closed another inch.
Omina looked back once with smoke already climbing around her boots.
"Go before the door decides courage is another bill."
Yun-Jin screamed Omina’s name hard enough to scrape her throat.
Ty jumped down the stairs toward the closing door, and the stair laughed under every ninth step.
