Two days later, the first-week sales data for Demon Slayer: Kimetsu no Yaiba volume four was released.
Volume three had posted 14.35 million copies in its first week, which had already been an industry-defining number. Volume four posted 18.4 million.
The people in the industry who understood what they were looking at went quiet when they saw it.
Two months ago, the highest first-week tankōbon sales figure in Japanese manga history had been 9.13 million copies. That record had stood for twenty-three years.
It had now been doubled.
The situation was not difficult to understand from the outside, even if it was difficult to accept. A work that had proven in another context that it could become a global phenomenon would naturally demonstrate considerable vitality when produced under favorable conditions.
The people who found Demon Slayer's popularity excessive or who felt the work's quality did not justify its numbers were not wrong in their personal assessment. They simply were not the ones deciding.
The people deciding were the tens of millions of readers who did not post online comments or participate in discussions, who simply purchased the journal each week and the tankōbon each time a new volume arrived, and whose preferences were invisible until the sales data made them legible.
For Rei and Hoshimori Group, the message the volume four numbers delivered was straightforward. Demon Slayer now had tens of millions of paying readers in Japan.
Across the global market, that figure was approaching the hundred million level. The work had moved beyond the category of a successful anime property and into something that required a different vocabulary to describe accurately.
Through September, the Entertainment District arc continued its broadcast.
The multi-threaded structure of the arc's early episodes moved with a naturalness that the earlier arcs had not quite achieved.
The protagonist trio arriving at the entertainment district under orders from the Demon Slayer Corps, rendezvousing with the Sound Hashira Tengen Uzui, then cross-dressing to infiltrate the establishments of the red-light district while tracking the demon hidden somewhere within it.
The tone was lighter than anything the series had done since before the Natagumo Mountain arc. Funny, relaxed, unhurried.
The viewership ratings did not continue rising without limit, which was entirely expected. For a work that had reached eight percent, the difficulty of adding one more percentage point exceeded the difficulty of producing ten new works that reached seven percent.
Not every television viewer in Japan was interested in animation regardless of the quality. There was a ceiling somewhere, and the series was approaching the region where it would begin to encounter it.
The Demon Slayer Mugen Train arc film completed its theatrical run in early September.
Final figures: overseas total, 34 billion yen. Domestic total, 72 billion yen. Global combined total, 106 billion yen.
With the film's theatrical run concluded, the full-scale development of the Demon Slayer IP began in earnest.
Games, live-action adaptations, clothing lines, figures, replica swords, and an extensive range of merchandise across dozens of categories.
Shipping demands from markets across the world were passing through Rei's IP operations company and being coordinated with the relevant manufacturers and distributors.
For the first time since the film's release, these logistics had been structured well enough that they were no longer pulling Rei's attention away from his creative work at random intervals.
He used the freed time to bring five new project folders to Himari's office at Illumination Production Company.
Himari looked at the folders on her desk. She read the labels. She took a sip of water. She read them again.
Attack on Titan. Your Name. No Game No Life. Higurashi: When They Cry. Summer Time Rendering.
Two minutes passed.
"Are you serious? Five works?"
"These are all concepts I developed back in high school. Last year when I was tidying the house I found an old notebook with the original ideas and spent the following year fleshing them out into complete drafts," Rei said. He knew what she was thinking, and the actual explanation was not one he could give her.
"The two most important are Attack on Titan and Your Name. The other three have genuine creative merit but more limited commercial reach. For the first two, I want our own production teams handling the work directly. For the remaining three, we manage the main process and outsource to top-tier industry partners wherever the capacity is short."
"You have already planned all of it," Himari said.
She set the folders down and looked at him directly.
"You are a creator with a global reputation now. That reputation requires care. Ten years sharpening one sword is better than producing work simply to maintain a release schedule. Even if you produced nothing new for several years after Demon Slayer concluded, your position would not be threatened.
But one failure in your resume breaks that. It affects your personal standing and the value of every IP attached to your name."
"I understand this better than you do. But time does not wait. These are concepts I am genuinely confident in, works I would not be bringing here if I had any doubt about whether they could stand alongside what I have already produced. I would not put the name Shirogane on something I was not certain of," Rei said.
"You really are..." Himari picked up the first folder and opened it.
She read in silence for a while. Then moved to the next.
An hour later she looked up from the fifth folder.
"These are genuinely interesting. All of them except Higurashi: When They Cry, which reads as slow at the start. The other four pulled me in immediately. Especially Summer Time Rendering and Attack on Titan."
"Higurashi and Summer Time Rendering are structurally similar works. They are both slow to open by design. Higurashi is not boring; it requires patience to reach what it is building toward," Rei said.
Himari sat with this for a moment, then exhaled.
"Fine. I will not argue the point. The Demon Slayer production is nearly complete through the Infinity Castle arc, which means a substantial number of staff will be available. Five simultaneous productions is a significant pressure on the company, but it is not impossible."
"There is no need to rush all five. Attack on Titan can take over from Demon Slayer in April or May. Your Name goes into the following summer season as a theatrical release. The remaining three can develop at whatever pace the teams can sustain."
"Understood. I will call a company meeting this afternoon." Himari looked at him and then added, in a different tone: "You are in your final year of university and about to graduate. As a friend, not a professional contact: you have your entire life ahead of you for this work. Your youth is the one thing you genuinely cannot recover later."
"I know what you mean," Rei said. "Youth passes whether you pay attention to it or not. Better to actually live it."
"What does that mean?" Himari blinked.
"Young people should do young people's things," Rei said. "I am not a workaholic. I brought five works today, but I will only be deeply involved in two of them. For the other three, I am a supervisor at most. In this final year of university I intend to actually experience the tail end of being a student.
At minimum I will learn the names of seventy or eighty percent of my classmates. Otherwise the graduation photograph will be a collection of strangers." He laughed.
What the Japanese animation industry had completely failed to anticipate was that Rei, standing at the front of that industry, had already begun laying out comprehensive plans for the following year's market while everyone else was still processing what the current year had produced.
At his current position, he did not need to maintain this pace. His standing in the market would not erode simply because he stopped releasing new work continuously. The momentum of what he had already built would sustain his reputation through an extended quiet period without difficulty.
The reason he was not taking that quiet period was simpler than any strategic calculation. He genuinely loved doing this. Bringing the works he had valued in his previous life into this world was one of the specific pleasures of his current existence. The money that resulted from doing it was a byproduct, not the point.
While Rei was occupied with these arrangements, the Demon Slayer: Kimetsu no Yaiba Entertainment District arc moved through its setup phase and arrived at its central antagonist.
Upper Rank Six, Daki.
"She is quite striking."
"The sense of threat from Daki is not as overwhelming as I expected from an Upper Rank."
"This should be the first powerful female demon to appear as an arc boss in this series."
"There was Tamayo before her."
"The identity reveal felt too easy. By the second or third episode, basically everyone had guessed who she was. And her combat ability so far has not produced anything that feels genuinely threatening.
Manipulating sashes is structurally similar to Lower Rank Five Rui's thread manipulation. It feels like the abilities are covering the same ground."
"She is clearly not in the same category as Akaza. Akaza gave the impression that the protagonist trio would be destroyed immediately. Daki seems to be struggling against them in places. Did the protagonists improve too quickly?"
"Overall it is still very enjoyable. We just have to see how the flashback plot develops."
"Everyone is waiting for that part."
"Who watches Demon Slayer primarily for the combat? Everyone is here for the memory sequences. The Mugen Train arc had Rengoku's family. The Natagumo Mountain arc had Rui, and Tanjiro and Nezuko together. The Entertainment District arc has not shown its hand yet on that front. But if there are no memory sequences, it would not be Demon Slayer."
"I used to get frustrated at the flashback structure and want to complain about it. Now I actively look forward to it. Something has changed in me."
"Shirogane-sensei seems quiet this year by his own standards. In previous years there were at least two serialised works. This year so far there is only Demon Slayer."
"He is also a person. We have to allow him time to breathe."
Through the end of September, the Demon Slayer: Kimetsu no Yaiba Entertainment District arc viewership ratings held steady in the eight percent range. The series continued to dominate trending lists and forum front pages across every major platform. The audience's mild reservations about Daki's threat level relative to Akaza had not produced any reduction in their engagement with the work.
On the final day of September, Rei received the news he had been anticipating.
Misaki had agreed to resign from Hoshimori Group and join his IP operations company as CEO.
The resignation process was handled smoothly through coordination between Rei and Hoshimori's management. Under Rei's mediation, Hoshimori waived the terms of the non-compete clause in her contract without significant friction.
The person taking over Misaki's editorial responsibilities for both Rei and Miyu was a young editor named Nao Fujimoto, a recent graduate who had spent her first year in the industry being trained directly by Misaki.
Placing the two mangakas with the highest potential in the country, and arguably in all of Japan, in the hands of her own protégé was the final act of care from Misaki toward the person she had been mentoring.
Once the transition was confirmed, Rei moved immediately to replace the professional manager at the IP operations company.
In October, with Misaki taking operational control, the company's first major public action was a joint announcement with Illumination Production Company.
Five new Shirogane anime works. Two companies collaborating on production, operations, and promotion.
Television anime series: Attack on Titan. Higurashi: When They Cry. No Game No Life. Summer Time Rendering.
Theatrical anime film: Your Name.
The announcement included promotional images for each work.
Attack on Titan: a confrontation image showing three small figures against the steam-obscured mass of the Colossal Titan looming above them.
Summer Time Rendering: a single figure, the protagonist, pressing a handgun to his own forehead, his expression composed.
No Game No Life: two siblings standing hand in hand with complete confidence in the centre of a vast and fantastical world.
Your Name: a meteor descending through a night sky, a boy and a girl looking up at it from below.
Higurashi: When They Cry: a group of characters standing together at the centre of the frame, one holding a baseball bat, one holding a kitchen knife, one holding a syringe, every face wearing an expression that could not be accurately described as a smile.
Nobody in the public announcement had enough context to understand precisely what these five works with their strikingly different art styles were going to be about.
That did not matter. Rei's existing fan base responded as though a starting pistol had been fired, and the media treated the announcement as the industry event it was.
Across Japan's animation industry, the collective expression was something between disbelief and despair.
"Has Shirogane-sensei lost his mind?"
"I was wondering why there was only one serialised work this year. He was saving it all for one announcement."
"Is this a pace that a human being can actually maintain?"
"He is genuinely not interested in leaving his peers any room to breathe."
"Every major trending list is full of Shirogane-sensei right now. This is a different level of public presence."
"Shirogane Animation's CEO is Misaki? That is his manga editor."
"She was never a nobody. She is the daughter of a well-known mangaka and has a personal net worth in the multi-billion yen range. After several years working alongside Shirogane-sensei, she has become the CEO of a major IP company. The trajectory makes sense if you know her background."
"And that mangaka suspected to be Shirogane-sensei's girlfriend is Misaki's younger sister. Also in her early twenties, also with substantial inherited assets, and her earnings from manga serialisation alone over the past few years are already in the hundreds of millions of yen. They are all exceptional people."
"Five new works and still no continuation of Arcane, One-Punch Man, or Hunter x Hunter. Where does he find the energy?"
"Patience. The subsequent chapters will come eventually."
"Next year is going to be the most significant year in the history of Japanese animation."
Announcing works early, before production was fully staffed and before broadcast dates were confirmed, was standard strategic practice. The earlier the audience's anticipation was established, the more time the promotional momentum had to build.
Misaki had moved quickly after taking operational control of the company. Beyond the announcement itself, she had begun a thorough review of the existing IP licensing arrangements and the financial operations that had been running under the previous manager. What she found in that review confirmed the instinct Rei had described to her at the barbecue. She addressed it without sentiment.
In Japan's animation market through October, Demon Slayer remained the dominant property by an unchallenged margin. But something in the atmosphere of the fan community had shifted slightly.
For the first time since the Entertainment District arc began, a meaningful portion of Rei's audience was looking past the current work and toward what was coming next year.
