Production and performance

Ishiijirou was credited as the story composer in 'New Sakura Wars.'

428 buttons and text rhythm

Looking back on the production of "428" in 2013, Ishiijirou said he had the performers follow the rhythm of the game's thinking to process buttons and move the text flow.

The production burden of adjustment at each location

The placement of text and sound timing in "428" needed to be adjusted step by step. He believes such meticulous arrangements increase production costs.

Roles and handovers in "428."

In 2018, Jiro Ishii said in his review of "428" that up to seven main characters serve the event, ultimately converging toward a central goal. The script starts with two characters from the same event, then expands on the stories of the cameos; After preserving the complete main storyline, the story is repeatedly rewritten and staggered in time and place, making the connections between characters gradually become distant.

In '428,' Ishii asks Abiko to write an extra story based on the existing Suzune setting and has him read the main story in its form first. By the time of "TRICK×LOGIC," Ishii started from the mystery competition format of "Armchair Detective" and invited Abiko to discuss gamification with him during the planning stage.

Script work for 'New Sakura Wars'

In 'New Sakura Wars,' Ishii first organized the SEGA project into narrative plot, identifying each character and action; Takaaki Suzuki further expanded the dialogue and specific scenes, forming the script draft before entering the game. Ishii checked the finished draft and found discrepancies with the outline to discuss and adjust it. He also deliberately avoids revealing some background settings to prevent new players from being overwhelmed by information about the main storyline.

Ishii and Suzuki left the game's production process after the script was delivered, and later learned about the changes made during the recording phase between Sumire and Yasha. Ishii read the revised dialogue, re-examined their images, and applied this understanding to the later manga and anime.

The commission for the extra story of '428'

When the main script for '428' was completed and preparations for filming began, Ishiijirou invited TYPE-MOON to create an extra story about Kanan. He hopes that the chain of war, revenge, and hatred will be expressed through Nasu's fantasy, ultimately preserving a hopeful ending and avoiding directly including these elements in the main story.

Hide the main theme with different main characters

Ishii Jirou explained that "428" initially deliberately avoided directly revealing the theme, giving each of the five protagonists a different theme, temporarily obscuring readers from the common theme. After playing the show, Takeuchi Takashi explained the fast pace of the work with "24" and suggested inviting artists to imitate the characters in advertisements.

Character name change in 'Invincible Teacher'

According to Yoshinori Terasawa's recollection, he personally called Ishiijirou to ask about the reporter character for "Invincible Teacher." Ishii replied that no additional requirements were required and could be freely made. Terasawa immediately changed his original name to Midori Mihokawa.

Filming of "428" on location

In a 2010 interview, Ishiijirou recalled that the van explosion scene in "428" was originally planned to be in front of the Shibuya Pantheon, but after that location disappeared, it was relocated to Koen-dori. The plan in front of the Apple Store was also shot in front of United Arrows because the shadows from morning light were unfavorable for compositing. To determine whether filming in Shibuya was feasible, he handed the script to Yasutaka Mouri for discussion; The other party responded that although it was difficult, it was worth the challenge, so he proceeded with the on-site shooting.

Photo review and script handover for "428."

"428" uses digital photography, allowing for on-site inspection of results, but it also makes it harder for the team to compromise and takes more time. To avoid using her authority to disrupt the shooting directives, Ishii left the import and inspection of a large number of photos until the night after shooting, handling them alone in her rented Shibuya office. The script was roughly outlined by time period, then rewritten by Kitajima Yukinori, with the team gradually finalizing the specific settings through discussions; This horizontal organization makes it easier to fit the game system.

Cast and costume choices for "428."

After finishing the outline and writing the script for '428,' the casting began to be made. Ishii emphasizes the expressive quality of the photos and considers whether the staff can shoot on site in Shibuya, thus inviting models and entertainers. The story focuses on a single day, reducing the number of garments; Producers invite stylists and borrow clothing from multiple brands, allocating budgets to garment quality.

"428" visual and dialogue experiments

Ishii added prompts and clear flowcharts for "428," and designed the animation with a recessed timeline to create a sense of overall continuity. He had created scenes with voice actors' voices, but felt that the expressions already visible in the photos blended with the voices and felt a sense of discord, so he ultimately did not include the voice lines. The scene before 109 after Kana enters the bad ending is replaced by a composite photo of Koichi Nakamura's phone call; Ishii also admitted that the tracker might leave behind minor plot contradictions even after stopping.
