Chapter 22. Numbers Save

I. Five-Fifty

A winter morning came to the glass-walled office on Omotesandō.

The keyaki had dropped their leaves; bone-like branches scored the sky. From the top floor, the pedestrians on the street below were the size of beans. Not one of them thinking, as they walked, about their own body. To Rui Takatsuji, this was strange. That they could not think.

Five-fifty in the morning. Rui was already at her desk. The same time every day. Not up at six. Working at six. The five-fifty was for that.

She set the silver-rimmed smart-glasses on her nose and closed her eyes. The glasses started and projected thin luminous letters onto her retinas.

Weight 52.3kg Body fat 18.7% Lean mass 42.5kg BMI 19.2

The figures from last night’s measurement before sleep. Rui confirms these first every morning. Before brushing teeth. Before coffee. The numbers decide the outline of the day.

Today’s numbers were in order. The same as yesterday, last week, last month. This body was built on a strict intake-expenditure ledger. Error of plus-or-minus a hundred grams. That was the shape of will. What has been put into numbers, is will.

Rui flipped the glasses’ menu with a fingertip. A report file opened. The one the intelligence officer on her team had submitted three days ago.

Rumour of a trainer at a small Aoyama studio who reads the body’s story. She appears to hold something our Veil scan cannot read.

Rui had been reading this line over and over. Each time, the eyes behind the silver rims narrowed a fraction.

Reading the body’s story. It smelled of sentiment.

But — something our Veil scan cannot read. That part alone hooked her attention. That the industry’s most precise full-body scan could not read a thing. What that thing was, Rui did not yet know.

II. The Girl in the Dark

The time before she met the numbers, Rui called the time I stood in the dark.

At twelve, Rui Takatsuji did not want to count her body. To count was to confront. To confront was to acknowledge. To acknowledge was to be defeated.

She could not bring herself to mount the scale. In front of the mirror she was always clothed. For PE she changed in a hidden corner where no one could see. She had quit swimming. The swimsuit her mother had bought slept in a drawer, price tag still on.

Her classmates were not, necessarily, cruel. No one pointed at Rui’s body and laughed. But there were gazes. At pool time, naturally missing. In the circle of thin girls running fingers along each other’s collarbones, Rui was outside the ring. To be outside was, itself, already a verdict.

Her mother said: You’re healthy, so you’re fine. Her father said: You worry too much.

But Rui’s heart was not healthy. A vague dread caked the bottom of it. The feeling that her body was not her own. The outline blurred; she could not tell where she began and ended. A terror without boundary, like standing in the dark.

She could tell no one. To say it would be to acknowledge it.

III. The Numbers That Gave Her an Outline

She met the numbers at thirteen, in autumn.

Referred by a pediatrician, she was taken by her mother to a university hospital’s pediatric lifestyle-disease prevention programme. Led by the hand down a white corridor. The smell of disinfectant. The cold light of fluorescents.

The programme was thorough. Morning weight logs. Weekly body-composition measurement. Three-day food records submitted to a nutritionist, intake calories calculated. Exercise managed in steps and heart rate. All of it, numbers.

On the first measuring day, Rui did not cry. She could not. The nurse had read the numbers off dispassionately, as office. Without sentiment. Without judgement, without pity.

Weight 58.2kg Body fat 31.4% BMI 22.2

The numbers were only numbers. Cold, hard, unmoving. They did not hold Rui’s dread — whether she was ugly, fat, lazy, worthless — the things that swirled in the dark. They only set down the facts that were there.

That night, for the first time, Rui saw her body as a thing that could be measured.

She had not been a vague ugliness. She was a body with a clear outline: weight 58.2kg, body fat 31.4%. If there was an outline, the outline could be moved. Change the input, the output changed. It was cause and effect, physics. Not terror.

In three months, the weight dropped by four kilos. Body fat fell five points. The numbers moved every week, a little. Each time they moved, the dark at the bottom of her chest receded. The boundariless terror gained a boundary line. Rui learned her body was a thing she could move by her own will.

That, Rui called salvation.

She had been saved. By numbers. The vague dread had been given form and boundary. The girl who had stood in the dark was handed, measured, the extent of the ground at her feet and the height of the sky above.

Emotion had been unreliable. Her mother’s you’re fine, her father’s too much, the silence of her classmates, Rui’s own self-loathing — all of it vague, shifting, not saving.

Only the numbers had saved her.

IV. The Advertisement

Thirteen years on.

Rui Takatsuji, twenty-six. Veil’s chief body analyst. One hundred and sixty-eight centimetres, fifty-two point three kilos, body fat eighteen point seven per cent. Every number where it was planned.

Rui’s body was Veil’s billboard. On the large vision above the main entrance of Mirage Omotesandō, Rui’s full-body scan image ran in rotation. Numbers overlaid; the measurements of each region floated as luminous text. It was an ad, and at once a declaration. —— This is the finished form of a body ruled by numbers.

Customers saw Rui’s body first. And wished to become like it. That wish, Veil turned into numbers. A forty-second scan. Per-region dimensions, body fat, muscle mass, balance. All of it numerical, analysed in the cloud, a target value set. The customer sees, in numbers, the present position and the destination of their own body.

Clear, Rui thinks. The body must be clear. Ambiguity misleads. To be misled is to suffer. Rui does not forget the dark before the numbers. That is why she hands people numbers. To the one standing in the dark, she measures the ground at their feet and gives it. That is Veil’s principle, and Rui’s belief.

“Takatsuji-san.”

With a knock, a subordinate’s voice.

“Come in.”

It was Sakuma, from the analysis team. Two years her junior. A tablet in hand.

“Last week’s new-user analysis. The weekly summary.”

“Set it down.”

Sakuma set the tablet on the desk. Rui picked it up and scrolled. A hundred and twenty-three new users. Conversion to paid plan after scan, twenty-three per cent. Plus-two points on the week.

“Twenty-three. Not bad, but improvable.”

“Where.”

“Twelve per cent drop off within three days of scan. Analyse the churn reason for this layer. Is the presentation of numbers too weak, the target setting too soft? Or —” A beat. “Is emotional follow-up thin.”

“Emotional, ma’am?”

Sakuma looked surprised. That Rui should say emotion was rare. Emotion is error, she said often. The team believed Rui denied emotion.

“Do not mistake me. I don’t say to value emotion. To handle it. What does the user feel when they see the number. Fear, relief, urgency. That emotion drives behaviour. Emotion itself is error, but ignore error and the model’s precision drops.”

“Understood.”

“Three days. Churn analysis. In numbers. Not in feel.”

“Yes.”

Sakuma bowed and left. Rui looked at the tablet screen. Columns of numbers. The outlines of people’s bodies, neatly lined.

This is right. This is how people are saved.

V. The Unreadable Thing

After Sakuma left, Rui opened the report from three days ago again.

The trainer who read the body’s story. The small studio in Aoyama, Life Compass. A measurement room in the basement, they said. The name, Seri Himuro. Twenty-four.

Rui put the name into a search engine. Hits: the studio’s website and a small fitness-adjacent review site. No loud exposure. There was a social-media account, but few posts. She was not conspicuous.

But the reviews were abnormally high. Five stars, average 4.9. A consistent pattern in the text.

For the first time, I could forgive my body. I didn’t feel judged by the numbers at all. I was measured, but I didn’t feel judged. Strange.

Rui frowned. Measured but not judged. A contradiction. To measure is to evaluate. To produce a number is to show present position; where there is present position, there is a gap to the ideal. The gap drives action. That is the purpose of measurement.

Not judged — did it mean not measured? Or was the result blurred? Either way, a method of wrapping a person in ambiguity. To Rui it did not look like kindness. It looked like softness.

Softness does not save.

But — something our Veil scan cannot read. The one line, thorned in.

An unreadable thing. Rui disliked what she could not read. What she could not read, she could not control. What she could not control was either dangerous, or valuable. One or the other.

And she had one more piece of information. The rumour of an app the trainer used. The name —

Contura

Rui turned the name in her mouth. Contura. Outline. From the English contour. The outward form of the body. And, beyond it, something.

The app was not on the public market. Not on the App Store or Google Play. Something extremely limited, closed. No official information existed. Only rumour, spreading by word of mouth.

When it measures the body, the app reads aloud the body’s “story.”

Story — Rui frowned again. Sentiment, the head understood. There is no story in numbers. Numbers are facts. To project emotion onto fact is mere human interpretation.

But.

If that were a real analysis engine.

Rui’s thinking turned there.

If Contura were not a sentimental app but something equipped with — a kind of analysis algorithm Veil did not have — something that could predict, from the combination of body numbers, a person’s behavioural pattern or psychological tendency. And they were calling that insight.

That was what Veil wanted.

Numbers tell a person where they stand. But numbers alone do not move people. What keeps them from moving is emotion. Fear, urgency, resignation. The numbers are too cold; people look away. Reality is too painful to face.

But if. If you could drape the numbers in a wrapping called story. If you could translate numbers into a person’s story.

People would not only receive the numbers, they would believe them. Accept them. And move. Sign, continue, pursue the target.

Add story to numbers. What would happen to the market.

Rui’s eyes narrowed. Beyond the silver rims, cold light ran.

It would be overwhelming.

Veil’s precision in numbering was first in the industry. Add to that a layer of story. Skeleton of numbers, flesh of story. A complete model of the human body. It would trample every competitor.

And for that, she needed the analysis engine Contura was said to have. Rui wanted it for her own. The belief in numbers allowed it.

VI. The Thirteen-Year-Old’s Notebook

Rui opened the desk drawer. In the back was an old notebook. No title on the cover. She opened the first page.

The thirteen-year-old Rui’s hand.

Weight 58.2kg Body fat 31.4% BMI 22.2

And beneath, in pencil, in a trembling hand, an addition:

I’ll try hard.

Only that. But to Rui, this notebook was scripture. The evidence that numbers had saved a girl. The first outline the numbers had handed to the girl standing in the dark — the ground, and the sky.

Rui closed the notebook. Returned it to the drawer.

And stood. Beyond the glass window, the Omotesandō street spread out. The winter-morning light whitened the asphalt. People walked. Without thinking of their bodies.

They are still in the dark, Rui thought. Hand them numbers. Give them outlines. Then they will be saved. As I was.

That was Veil’s principle, and Rui’s reason for being.

VII. Wings for the Numbers

Rui pressed the intercom.

“Sakuma.”

“Yes.”

“Come.”

In thirty seconds Sakuma was back. Rui set the report before him.

“Give me the continuation.”

“The Aoyama studio.”

“Yes. Seri Himuro. Twenty-four. Trainer at Life Compass. Investigate. Background, history, client base, measuring method. Everything.”

“Understood.”

“And —” Rui dropped her voice a register. “There’s an app she uses. The name is Contura. Not on the public market. Something closed. Developer, provider, the inside of the technology. Wash all of it.”

“Contura.”

“It means outline.” Rui lifted the corner of her mouth a shade. Something like a smile. But the eyes did not smile. “An interesting name. The outline of the body. The same thing we do.”

“Yes.”

“But they do not measure the outline in numbers. They say they read it in story. What that really is, I don’t yet know. Therefore — investigate.”

Sakuma took notes, nodding.

“Two weeks. Staffing at your discretion. Priority top. Rotate other work.”

“Understood.”

“Ah. And.” Rui appended. “Do not approach Himuro Seri. Investigate at distance. Our interest is not to be known, yet.”

“Understood.”

Sakuma bowed and left.

Silence returned. Rui stood at the glass.

Omotesandō’s keyaki. Bone branches. Winter sky. Cold, clear.

Contura. Outline.

She turned the word once more. The outline of the body. The power to read it. Not by number, but by story.

Sentiment, she thought. But sentiment, too, has its use. The power to move the human heart. Put that — on the wings of numbers.

Numbers save. That does not change. It is the belief at Rui’s root. That night, at thirteen, numbers gave an outline to the dark. Rui will not forget.

But there are people numbers alone cannot save. People who find numbers cold. People who receive numbers as verdict. To deliver numbers to them — a wrapping is needed. A story.

That, Rui was about to admit. To admit is not defeat. It is the expansion of strategy.

Numbers save. Story will be their wings.

On the desk, the smart-glasses chimed a notification. A new user, scan complete. Analysis begun.

Rui left the window. Set the glasses on. Numbers lined up on her retinas. The outlines of people’s bodies. Lined up, neat, measurable.

This is my field.

And Rui returned to the desk. She reads the numbers, analyses them, sets targets. She gives outlines to people’s bodies. That is what she does.

——

That same morning. In the studio in Aoyama, Seri Himuro was preparing for a new day. Airing the measurement room — the Circle — below. Laying out clean towels.

Seri did not yet know. That beyond the glass on Omotesandō, a cold eye had turned toward her. That the light called Contura was being aimed at by a shadow.

In Seri’s pocket, the old phone grew faintly warm. Coh seemed to have sensed something. But it had not yet become a warning. A premonition, almost. A faint wavering.
