Text and games
In developer interviews, he explained that his work often involves adapting written scripts into dialogue and plot suitable for game reading, and coordinating text with game presentation.
Ways to participate after independence
The depth of participation varies among different works. When talking about "The Inugami Family," he deliberately limited his work to introducing screenwriters and did not refer to this assistance as the main screenwriter.
Gunfire and diamond making
The supervision and performance credited to Kazuya Asano for "Gunshots and Diamonds" is credited.
Draft with branch delivery
Kazuya Asano recalls that the first script submitted for 'Kamaitachi no Yoru' already had branching scripts. Abiko not only writes deduction choices but also designs unfavorable paths after player misjudgments.
Discuss technical methods before writing
Before writing, Abiko explained to Abiko the practice of resetting and retaining memory in specific cases; This technical solution later became the basis for operating the hidden script.
The script and tips for "Street."
Kazuya Asano recalled in a 2018 panel discussion that about half a year before "Street" was completed, Koichi Nakamura felt that ZAP switching alone was not enough and hoped to increase player engagement with the visuals. Asano then added a vocabulary explanation TIP; During production, it was discovered that it could connect to ZAP and connect multiple TIPs into a small serialized story.
When discussing the initial draft of "Street," Asano said the team first prepared a hundred characters and stories, but couldn't realize them all, so they started with the more interesting stories. While working on other games, he continued writing "Street," first completing a worthy story and then connecting different characters.
Background and character silhouette formation
In a 2024 interview for the 30th anniversary of 'Kamaitachi no Yoru,' Kazuya Asano reflected that the original SFC required characters to be showcased due to the increased number of characters. Abiko Takemaru proposed using shadows for depiction, and subsequently created character layout storyboards; Koichi Nakamura decided to change the originally planned pixel background to import real-life photos.
Deleted footage after receiving objections
Asano recalled that the SFC original SFC originally had a screen of the first victim in 'Kamaitachi no Yoru' and received objections, so it was changed to briefly display color before switching to black and white.
The barely noticeable background gradually darkens
For "Kamaitachi no Yoru," Asano asked programmers to write instructions for the background to gradually darken, so that the same scene gets darker toward the end of the script, making the changes harder for players to notice. He drew inspiration from the "Dragon Quest" dungeon where pitch drops step by floor, transforming this progression into changes in visual brightness.
Kamaitachi no Yoru original music commission and selection
Asano requested character themes and deleted introductions for the original SFC work, allowing the music to evoke emotion right from the start and better match the text.
He chose 'Introduction' with snowy scenery and the title track for ominous bass; Kayama adopted Kato's enka concept, while Nakajima's other proposal was adapted to Mikimoto's theme.
