THE MOON · SIXTEEN MONTHS SINCE THE SHIP LEFT
The theft was scheduled for Thursday, which Urahara knew because he had chosen Thursday.
The Moon had no Thursdays of its own. The base ran on a week borrowed from a city nobody named, along with its weather.
On Thursday mornings the mess smelled of bread. People who eat bread on a schedule do not come apart on one.
The twenty-one finest minds ever lifted off the Earth lived here. They were as fragile as anybody and much worse at admitting it.
He stood at the serving hatch handing out rolls, because he liked to see who took two.
Marchand took two and ate one. The other went into his coat pocket, and he did not notice doing it.
He had shaved, which was new. He stood straighter than a man who ran a sample library had occasion to stand.
"I wondered about the night rotation," he said. "The cold-store count. It goes faster when the ring is quiet."
He had practised that. Urahara could hear the groove the practising had worn.
"Take it, take it, I've been trying to give the night rotation away for a month." He wiped his hands on the terrible coat.
"You'll want to know the inner seal on the vault runs a diagnostic at three. For eleven minutes afterwards it makes a great deal of noise and is no use to anybody."
"So if you're counting cold-store, count it then. You'll not be interrupted, and the log won't hold it against you."
"That is very helpful," Marchand said.
"It is, isn't it." Urahara beamed at him. "And don't let anyone tell you the night shift is lonely. There's nobody on this Moon who isn't carrying something around at four in the morning."
He thanked him. Then, at the door, he thanked him again.
Megumi looked up from his bowl.
He was twelve, and had spent six years among people who wore their faces like coats. He watched the librarian all the way out of the room.
"What's wrong with him?"
"Homesick," Urahara said. It was true, and not the whole of it.
The boy went back to his bowl in the way that meant he had noticed.
Three weeks earlier Urahara had left a lead-lined library case on a low shelf where a tired man would find it. It was exactly the right size for carrying something quietly out of a vault. He had built it himself.
He knew why Marchand would use it. There was a girl on Earth, and somebody down there had found her before Urahara did, and had made a father the offer that only ever needs making once.
He wanted one thing from Thursday. He wanted Marchand to use those eleven minutes and never once wonder who had opened them for him.
* * *
He watched it happen on a pane of glass propped against a teapot in his workshop. The glass showed him any corridor on the base he cared to ask it about.
The vault sat under the crew levels, in the oldest cut rock on the base. Three doors and a stairwell down.
Along the left wall a rack of drives held six years of readings on the strongest sorcerer alive.
At the far end a big man with a scar through his lip floated in a silent tank. He was the only thing down there Urahara had ever thought about hanging a curtain across, in case a boy ever came down the stairs.
In the middle, on its own plinth, sat a case holding seven things wrapped in paper and old cloth.
Each was the length of a child's hand, blackened and crooked and a thousand years old.
Every instrument in the ceiling had been unhappy about them for six years, and not one could say why.
Marchand came through the inner seal four minutes past three and worked fast. Urahara watched his hands with a craftsman's pleasure in another man's joinery.
Seven minutes left of the eleven.
His mouth had been moving since the second door. The microphone in that room was old and gave up nothing.
A frightened man alone says one word, and it is always a name.
Then he opened the case.
And a second pane lit at Urahara's elbow.
A corridor three levels up he had not asked it about. A door standing open. A boy in socks going left at the turning, towards the stair down.
None of that was in the plan anywhere.
He could drop three tonnes of door across that stairhead in a second and put the boy safely behind it.
But four levels below, a man with his hands in a case would hear it come down. A frightened man who hears a door slam runs. A man who runs gets found holding it.
The whole night only worked if nobody helped and nobody stopped anything.
So he went himself, and left the glass to mind itself.
He came round onto the landing with two cups, having run every step of it.
"Can't sleep?"
Megumi stopped. He looked at the second cup a beat too long. "Who's that one for?"
"You, as it turns out."
The boy took it and did not drink. "He took two rolls this morning. He didn't eat the second one."
"Did he."
"People do that when they're not coming back." Megumi turned the cup round in both hands. "And he said goodbye at the door. Nobody here says goodbye. They say see you at breakfast."
He looked up.
"Is he in trouble?"
Four levels down, eleven minutes went on spending themselves.
"Nobody's in trouble," Urahara said.
It was the first thing he had ever said to that boy that was not true in any direction. He noted the price.
"Bed. Be unbearable to a chemist in the morning."
Megumi went, because the man had never once lied to him.
Urahara walked as far as the corner. He did not walk after that.
The pane had not changed. That was the worst thing it could have done.
Marchand stood over the open case with his arms at his sides. Four of the seven were already in the lead-lined box. He had simply stopped.
His left hand was in his coat pocket, where he kept a photograph older than this base. Urahara had read that file six years ago.
He stood there ninety seconds more, and there was no knowing how many had gone before.
Ninety seconds is a long time in a room like that. With three minutes left of a gift, it is most of what a man has.
Move, thought Urahara. Go on. Move.
He could not knock. He could not say the man's name. Anything that told Marchand he was being watched would finish him where he stood.
So he pressed the intercom key and read the notice he had written that morning, in the bored voice of a man reciting paperwork.
"Night rotation, your attention. The lower service ring closes at half past three for recalibration. Apologies to anyone counting."
It was addressed to nobody, and it handed him a deadline. A frightened man can obey a deadline.
Marchand moved.
He took four, because four was what the moulded foam would hold, and Urahara had moulded four. He closed the box, put it under his arm, and left three in the dark without looking back.
The seal came back up at eleven minutes past. He was two doors above it.
The victim held the door. The thief walked through it. Nobody, technically, had done anything at all.
* * *
The corridor outside the airlock ring was cold at four in the morning, whatever the panel claimed. Urahara was in it when Marchand came round the corner.
The librarian stopped. Then he came on, because there was nothing else to do.
"You'll want this." Urahara held out a flask. "Colder out there than the numbers say. I've made it stronger than the boy's. You've a long way to go."
Marchand took the flask in the hand that was not holding the box. "I am only doing the cold-store audit."
"Of course you are."
The hand holding the flask had begun to shake. Marchand looked at it as though it belonged to somebody else.
"I don't think this is going to work," he said.
"It's been working all night. Ask it nicely."
They stood in the hum of the ring. Behind the wall a pump changed its mind and changed it back.
"How is Camille?"
Marchand's hand went to his pocket before he could stop it. "She will be seventeen in November."
"Sixteen is the worst of them, I'm told. Seventeen improves." Urahara nodded as though this settled a matter troubling them both. "She'll have got tall. They do it all at once, out of spite."
"Yes," said Marchand.
The ring hummed. Nothing else did.
"The resin trays are two behind on the count," he said. "If nobody gets to them by Friday they'll want doing twice."
"I'll see to it."
He brought the box out and held it in both hands, at the height of a thing handed over.
Urahara looked pleasantly at the wall and did not put out a hand.
"Ask me what is in the box," Marchand said.
Nothing came back at all.
"Please."
"Doctor." Urahara said it kindly. "Anything you tell me I have to write down."
That was the whole of it, and Marchand understood it. A man who confesses has to be arrested. A man who says nothing can be allowed to walk out of a door.
After a while he put it away under his arm.
"Mind the terminator, Doctor. The edge of the sunlight out on the ground. It comes up faster than the eye says."
"It would be a shame to be halfway through something delicate when the light finds you." The fan appeared and shut again. "And keep whatever you're carrying in an inside pocket. Vacuum's murder on the outside ones."
He was a decent man who had spent six years being a slightly different man.
For one breath the whole arrangement stood open between them. Nothing in it but two people being extremely polite.
Don't say it, thought Urahara. Say it out loud and I will have heard it.
"Urahara," he said.
"Drink it while it's hot. Keep your hands warm. And don't look back at the base when the light comes up, it does something unhelpful to the eyes."
Marchand nodded. At the corner he thanked him, which made three.
"Not at all," said Urahara.
Nine hundred metres of open ground, in a suit built for standing still in. At the end of it a hatch that had to be shut and gone before the sunlight reached that part of the rock.
Twenty-two minutes, by a sum Urahara had done a month ago.
At twenty-six he found the fan open in his hand and could not remember opening it.
He stayed until the ring lights cycled green, and then to nothing.
Out on the dark side something had opened like a curtain at the hour it promised, taken one man and what he could carry, and closed.
* * *
Afterwards he went down and stood in the vault with the three that were left.
The shelf above the plinth held forty-one notebooks in cheap covers. Gin liked the cheap ones because they lay flat.
Urahara took down the eleventh.
Inside, in tidy horrible handwriting, was Sukuna's technique taken apart the way a watchmaker takes apart a watch.
Sukuna had eaten his way across Japan a thousand years ago and nothing alive had stopped him. When he was finally put down, twenty blackened fingers were all that was left of him.
Thirteen of those sat sealed in the vaults of the sorcerers' own clans, where no hand would ever reach them. The other seven had cost Aizen years to gather.
They were the seven on the plinth.
Nineteen pages, corrected twice and finished, with a small and very smug fox drawn in the margin of the last page.
Under the fox, a note. Done. Nothing left in them worth the postage.
That note was the reason the theft had been allowed to happen.
Everything the fingers knew was already in the notebook. Gin had read them for six years and had finished the job. The technique was written down, all of it, in a cheap book that was not going anywhere.
The fingers themselves were still perfectly real. They were as dangerous as anything on this Moon and more dangerous than most.
But there was nothing left to learn from them. Giving four away cost the project precisely nothing.
Somebody down on Earth, clever and very pleased with themselves, would shortly believe they had robbed Aizen Sosuke.
Nobody had robbed anybody. They had been handed a present in the dark.
Urahara closed the case on the last three with one finger.
"You've nothing left to say," he told them. "Gin took the lot. Everything you ever knew is upstairs in a notebook with a fox drawn in it."
"Four wakes him up. All seven of the loose ones would make him ours."
He meant that plainly. Four fingers were enough to bring Sukuna back into the world. Thirteen were sealed where nobody would ever use them.
So the seven on this plinth were the whole of what any hand could hold. A man with all seven owns him.
The grin was where it always was and it had stopped reaching his eyes.
"And I don't think we want a pet," he said. "I think we want a reason."
Nobody steals a king to keep him in a drawer.
In a month, or a year, somebody down there would swallow the first of them. Then Japan would have its oldest problem back with its appetite intact.
Every clan and school and frightened man with a technique would have to become enormous or be eaten.
Most would be eaten. The rest would be worth meeting.
"It isn't complicated," he said. "You don't sharpen a world by leaving it alone. You put something in it that kills everyone who stays as they are."
It was not generosity, and it was not mercy. A man who intends to be the last enemy a world ever has needs the world to be worth the trouble of ending.
And the three still in the case were the leash. Sukuna would come back missing a piece of himself, and the only piece anybody could ever fetch him would be sitting on the Moon under a lamp.
He put the case back, sealed the door and took down the register.
Four slots stood empty in the diagram. He wrote the label in his cheerful hand.
*ON LOAN.*
"Grow well," said Kisuke Urahara, to a world three hundred and eighty thousand kilometres away that had just been handed a king. He set the hat straight on his head. "Don't dawdle."
The register had a second column, for authorisation. He left it blank.
The only hand entitled to fill it was four light-years away and had not been asked. Aizen knew nothing about any of this, and would not for a long time.
Urahara put the pen down. He preferred to present a thing finished.
