Having been through the Swordsmith Village arc, Japan’s Demon Slayer fan base had developed a specific relationship with the series’ structural rhythms. They complained in the fan groups. They also kept watching, and underneath the complaints was a particular kind of hope, a hope that some episode of the Hashira Training arc might produce a moment comparable to the Swordsmith Village finale, that the quiet arc would earn its place the same way the previous quiet arc had.

Strictly speaking, this arc did not have that episode. The plot moved without significant peaks. Training. The protagonist building relationships with each Hashira in turn. The emotional register stayed warm and light throughout.

The television viewership ratings dipped slightly as a result.

February arrived.

Seventeen days remained until the Infinity Castle arc film premiere. Two episodes of the Hashira Training arc were left in the television run.

Rei, alongside the promotional teams behind the other major spring holiday theatrical releases, began a circuit of cities for offline promotional events.

The trend held across every stop: the venues arranged for his fan meetings were inadequate for the crowds that arrived. 𝘧𝓇𝑒𝑒𝑤ℯ𝑏𝓃𝘰𝑣ℯ𝘭.𝘤ℴ𝘮

Other promotional tours in the film industry dealt with traffic from the fan bases of their cast members, which was substantial. What Demon Slayer brought was a different category of audience, one whose enthusiasm for the specific work they loved translated directly into purchasing behaviour rather than passive attendance.

On the major ticketing platforms, the first-day pre-sale box office for Demon Slayer among the spring holiday theatrical releases had already cleared 2 billion yen, ranking first across all films in the period.

At Shirogane Animation, Misaki had assumed operational control of the company’s finances on Rei’s behalf.

Large capital expenditures were within her authority without requiring individual approval. The promotional spending flowing out of the company accounts every day was running at a level she had needed a week to become comfortable looking at.

Domestic placements and international campaigns across dozens of markets simultaneously.

She was executing the plan Rei had laid out before handing operations to her, investing in promotion without hesitation at any cost threshold.

Rei had the capital to sustain this without concern about liquidity. He had no behind-the-scenes investors whose tolerance for spending needed to be managed. The financial structure gave him a freedom of action that the other productions competing for the spring holiday season did not have.

His stated requirement for the Infinity Castle arc had been simple and direct.

"I have only one requirement. The spring holiday season box office championship."

Misaki had been thinking about that line since he said it. When the Mugen Train arc released, she would have found the claim difficult to take at face value. The series had been building momentum at that point, but the fan base had not yet reached its full depth and the work had not yet demonstrated what it could do in a theatrical release.

The situation was different now. Demon Slayer had been present in the market for over a year. The fan base had been built across the Mugen Train arc, the Entertainment District arc, the Swordsmith Village arc, and the Hashira Training arc.

The television ratings were holding above eight percent.

The tankōbon average sales per volume were the highest in Japanese manga history and were tracking toward a final average of 35 million copies per volume.

The promotional budget committed to the Infinity Castle arc film exceeded every competing release in the spring holiday season by a significant margin.

Among all the films premiering during that window, Demon Slayer was the only one with confirmed simultaneous release across dozens of international markets on opening day.

On what basis would it not take the box office championship?

Misaki pulled up the negotiation results her team had compiled from their discussions with the major cinema chain managers.

The spring holiday season competition had already begun in earnest. The investors behind the six films releasing during the period were engaged in an active battle for first-day screening allocation, and the managers making those allocation decisions were working from the data available to them.

The sequel to the film that had closed its global theatrical run the previous July with a combined box office of over 100 billion yen was, naturally, the film the cinema chains were most interested in scheduling.

"This is the largest single operation I have managed since joining this company," Misaki said to herself. The pressure was real and specific and she found she did not particularly mind it.

The penultimate episode of the Hashira Training arc aired.

The tone was what the arc had been throughout: warm, unhurried, the characters training and talking and building the specific texture of relationships that the audience would carry into the Infinity Castle arc. The viewership held at 8.03 percent on Friday, February 7th.

Fans continued to complain about the pacing in the group channels. They also continued watching.

After the first ten days of February, Rei transitioned from the national promotional tour to events in the Tokyo area. He was not a person who needed to be reminded that breaking his health for the sake of promotional appearances was not a sound strategy.

Demon Slayer’s current momentum did not require his personal presence at every stop. With the New Year period approaching, resting properly was the correct decision. He rested.

Thursday, February 13th.

The spring holiday premiere was days away.

For the first time, the full weight of what was approaching had settled into the fan community’s consciousness in a way that the weeks of anticipation had not quite produced. The final episode of the Hashira Training arc was broadcasting tonight. After this episode, the television series was complete. What came next would only exist in cinemas.

The question circulating through every fan group and forum in Japan was the same.

Would Shirogane-sensei use this final episode to plant foreshadowing for the Infinity Castle arc? Would there be something in tonight’s episode that would make the film’s opening land differently, or harder?

"This is genuinely the last episode of the television series. After tonight, the story only continues in a cinema."

"I have been following this weekly since January of last year. Thirteen months. And it ends tonight and I have to wait for a film to see what happens next. I am not ready."

"The last episode of the Hashira Training arc. What could he possibly be putting in here to set up the Infinity Castle arc? Something about the Hashira individually? A final look at Muzan?"

"Whatever it is, Shirogane-sensei has earned the right to use this episode however he wants. If it is twenty minutes of Tanjiro doing push-ups I will watch every second."

"It will not be push-ups. He knows this is the last episode before the film. He is not going to waste it."

"Five days until the premiere. I have already bought tickets for the first screening on opening day. I have been thinking about this film for six months."

"Seven days until I see what happens to everyone in the Infinity Castle. I am terrified and I cannot wait."

"Muzan has known about Nezuko since the Swordsmith Village arc finale. Whatever is coming in the Infinity Castle, it starts from that. Everything the Hashira just trained for is about to be tested against the thing they have been trying to stop for the entire series."

"Please let Tanjiro be okay."

"He is the protagonist."

"Shirogane-sensei killed the Flame Hashira. Do not tell me the protagonist is safe."

"...fair."
