Early August, 1989.
The cicadas' drone echoed through the sweltering high-rises of Marunouchi. Heat waves from AC units warped the air above the asphalt, and in the distance the Imperial Palace greenery blurred in the shimmering haze.
Inside the President's office at Saionji Industries Headquarters, a humidifier puffed out a steady, cold mist.
Managing Director Endo stood formally in front of the desk, holding an encrypted telegram that had just arrived from Wall Street. A sheen of sweat covered his forehead, and his breathing sounded heavy in the climate-controlled room.
"News from Frank," Endo said, breaking the silence.
"The legal isolation for the hundred umbrella trusts and shell companies is in progress. To avoid alerting the U.S. Securities and Exchange Commission, all offshore accounts must maintain a total quiet period for the next two weeks. No abnormal capital movements are permitted, and no buy orders can be issued."
Satsuki sat in a wide leather swivel chair.
She wore a light beige cotton-linen dress, her long hair pinned back simply with a deep-blue tortoiseshell clip. She held a photocopy of the telegram, her fingertips tracing the rough surface of the thermal paper.
She applied slight pressure.
The paper fed into the shredder beside the desk.
The gears engaged with a harsh grinding sound, and fine white scraps fell into the transparent bin like snowflakes.
A two-week absolute quiet period.
For those massive overseas capital fleets, it was the price of crossing a minefield safely. But for the Saionji Family's overall strategy, time was always the most expensive resource.
On Basement Level 4, theoretical models for Extreme Ultraviolet, or EUV, lithography machines were still running day and night. Beyond hardware barriers like light sources and multi-axis machine tools, future chip manufacturing faced another fatal bottleneck: advanced packaging. When transistors shrink to the nanometer scale, the intricate circuits inside a chip require a specialized resin film — extremely insulating with a very low thermal expansion rate — for layer-by-layer stacking and isolation to prevent signal interference and short circuits.
Silicon Valley and Japan's semiconductor giants currently had no solution for this core substrate, known as Ajinomoto Build-up Film, or ABF.
In Satsuki's memory, the prototype for this material — one that would someday bottleneck global chip foundries — was currently sitting in a chemical waste bin at a food company.
Ajinomoto Group. The company had started with MSG and seasonings, but its basic chemicals division had accidentally synthesized a byproduct resin while researching amino acid polymers. The resin had perfect insulation and heat resistance, but its texture was too brittle and lacked flexibility, making it useless for traditional construction or food packaging. It was now slated for budget cuts and termination by senior management.
Using this fourteen-day capital window to acquire that overlooked piece of the tech puzzle for a negligible price — that was the plan she had drafted right after the black-box meeting.
The shredder's motor gradually fell silent.
Satsuki looked up at Endo.
"Managing Director Endo, in S-Food's product line for next quarter, there's a proposal for the 'Gokujō Series' microwaveable bento, correct?"
Endo paused, quickly recalled the details, and nodded.
"Yes, Young Miss. S-Food plans to launch high-end fresh food in autumn and winter. However, current polyethylene containers tend to deform and release odors under prolonged microwave heating. R&D is looking for a more heat-resistant sealing film."
Satsuki stood and smoothed the slight wrinkles in her dress.
"Ajinomoto Group isn't just our major seasoning supplier — their basic chemicals division also has deep research into amino acid resin materials."
She picked up the landline on the desk and handed the receiver to Endo.
"Set up a meeting with the executive director of Ajinomoto's food division. Tell them S-Food is prepared to sign a five-year exclusive long-term contract for seasonings. And incidentally... I want to tour their chemical lab to see if they have a suitable heat-resistant film for our new bento."
Endo took the receiver, visibly relieved.
Wonderful. The Young Miss is finally doing normal business.
This was a standard, mutually beneficial visit. S-Food controlled the fresh-food supply chains for the three major convenience store chains — 7-Eleven, FamilyMart, and Lawson — plus S-Mart supermarkets across Kanto. The lure of a five-year contract would make Ajinomoto's senior management open every door.
"Understood. I'll arrange the motorcade and the visitation letter immediately."
...
The car engine replaced the fading sound of the shredder. A black Nissan President glided over the asphalt of Chiyoda Ward and stopped smoothly in front of a building with mid-Showa architecture.
Ajinomoto Group Headquarters.
Setting aside Satsuki's surprise at the loud welcome — Ajinomoto employees lined up in two rows at the entrance — she was escorted to the high-end tasting room on the top floor.
The room was designed for VIP clients to sample products immediately. Boiling kombu dashi roiled in a copper pot on a stainless steel cooking station, releasing thick white steam. The vapor fogged the heavy glass windows, completely blocking the hot Tokyo street scene outside.
The air was saturated with a penetrating umami scent.
The executive director of Ajinomoto's food division stood by the long table, beaming. He clutched a beautifully bound quote sheet, his cheeks flushed with excitement.
S-Food controlled the fresh-food arteries of the three convenience giants and S-Mart. Their production lines for millions of onigiri, bento, and oden consumed hundreds of tons of kombu extract and composite seasoning powder daily.
And today's discussion was for an exclusive five-year supply contract.
If he got Satsuki to sign, Ajinomoto's next-quarter profit report would spike exponentially. And he himself would have the performance to push into the group's core board — maybe even aim for president.
Seeing Satsuki enter, the executive director rushed to greet her. Holding the quote sheet with both hands, he leaned forward, trying to get close to the financier who held the retail lifeline.
"Young Miss Saionji, welcome. We've already—"
He didn't finish.
Fujita Tsuyoshi stepped forward. His tower-like frame inserted itself between the executive director and Satsuki. The man was sweaty despite anti-perspirant spray, and if he hadn't been the negotiation target, Fujita would have pinned him to the floor.
The executive director froze.
He looked at the bodyguard, his smile stiffening. His outstretched hands hovered awkwardly.
He recovered quickly, withdrew his hands, and pulled a white handkerchief from his pocket to wipe his forehead. Then he stepped back two paces, restoring a safe social distance. His smile became even more deferential than before.
"Apologies, I was too excited," the executive director said, nodding repeatedly. He respectfully handed the quote sheet to Endo. "Please, have a seat. This is our pride — top-tier dashi. Please taste it."
Satsuki's expression showed faint displeasure at the overeager welcome, but she walked to the long table and sat down.
She picked up the small white porcelain bowl, used a porcelain spoon to take a mouthful of dashi, and brought it to her lips.
She closed her eyes and swallowed.
The warm liquid slid down her throat, rich umami spreading across her tongue. As the inventor of MSG and a century-old brand, Ajinomoto's industrial purification was indeed impeccable. Even ignoring the "hidden target" in the basement, their standardized product alone made them S-Food's ideal partner.
She set down the spoon. It hit the cork coaster with a soft, dull sound.
"The flavor is very good," Satsuki said with a slight nod, offering a proper, gentle smile. "Your umami extraction technology is still top-tier in the industry."
The executive director exhaled, rubbing his suit pants with his hands.
"As long as you're satisfied, we can arrange signing at any time! For production volume and supply cycles, we'll commit the entire company to meet S-Food's needs!"
Satsuki took a small sip of warm water beside her.
The glass returned to the coaster.
"Mr. Executive Director, S-Food can sign this five-year long-term contract," she said.
The executive director's eyes lit up. He excitedly rubbed his pants again, ready to bow in thanks.
"However," Satsuki said, her tone shifting. Her gaze moved past his shoulder to the hot Tokyo street outside the glass.
"S-Food is launching the 'Gokujō Series' bento next quarter — designed for long microwave heating. Current polyethylene films deform easily at high temperatures and release trace toxins. It's a thorny problem."
Satsuki frowned slightly, showing well-timed distress.
"To find an extremely heat-resistant, insulating new resin film, our procurement team has visited every packaging factory in Kanto. I have to rush to Chiba this afternoon to see Sumitomo Chemical's lab."
She sighed softly and dabbed the corners of her mouth with a white napkin.
"If even Sumitomo Chemical can't provide a suitable material, this new project — with billions already invested — will likely be shelved indefinitely."
The executive director's breathing hitched.
His brain raced. Sumitomo Chemical. A chemical giant. Ajinomoto, as the originator of MSG, was fundamentally also a large chemical enterprise built on amino acid extraction.
A massive opportunity had landed in front of him. If he could monopolize S-Food's high-end packaging supply and steal the business from Sumitomo Chemical, the doors to the core board would swing open.
"Young Miss Saionji!"
The executive director stepped forward abruptly, his leather shoes scraping a short, harsh sound on the wood floor. Fujita Tsuyoshi's hand twitched toward him.
"If you're looking for new resin materials... our company might be able to help!"
Satsuki turned her head slowly. Surprise and doubt flickered in her eyes.
"Ajinomoto? Your company is certainly an expert in seasonings." Her gaze swept the pot of boiling dashi. "But resin materials?"
The desire to impress a powerful figure overrode the executive director's caution. He completely forgot his earlier comment about cutting that department's funding, desperate to seize the chance for merit.
"Food is just our application side!" the executive director said urgently, waving his hands. "In amino acid polymers and basic chemistry research, we have decades of heritage! Our basic chemicals division has done extensive byproduct research on specialty resins."
He swallowed, then bent into a deep, respectful invitation.
"If you don't mind, could I ask you to postpone your trip to Sumitomo Chemical and tour our underground laboratory instead? Perhaps the heat-resistant material you need is right here."
The lounge went silent for two seconds.
Boiling dashi hissed steam.
Satsuki studied the executive director's eager, treasure-offering expression.
She didn't agree immediately. Instead, her white-gloved fingers tapped the tabletop lightly.
Tap, tap.
The slight sound struck the executive director's nerves. Sweat slid down his cheek onto his dark-gray collar.
"Since the executive director recommends it so highly," Satsuki said, standing and smoothing her dress, "let's take a look. The Saionji Family's time is very precious. I hope your researchers don't disappoint me."
The executive director exhaled in relief.
"We won't disappoint you! I'll lead the way right now!"
He turned and jogged toward the elevator, jabbing the down button impatiently.
Leather shoes and heels clicked alternately on the wool carpet.
The group entered the elevator. The floor numbers on the panel descended, skipping past the lobby.
