What the developer says
This game is an "AI Reality" production, with generative AI at the core of its creative process. All AI-generated assets are pre-rendered; no content is generated live during gameplay. Visuals: Backgrounds use a combination of photographs taken on location in Fukuoka and images created with image generation AI. Event CGs and character images were created using image generation AI. Video: Some video assets used in in-game sequences and promotional materials were produced using AI video generation technology. Audio: BGM and some sound effects were created using AI music generation services. Story: The scenario plot and script were written by a human creator. AI was used as a brainstorming and proofreading assistant, but all creative vision, decisions, and final writing are entirely human-driven. At Sakura ARC, we position AI not as a mere tool, but as a co-creator — challenging what a single creator can achieve at the highest quality.

| AI judgment deepseek-flash | Major AI · mixed signals, high confidenceReasoningThe disclosure states AI image generation produced backgrounds, event CGs and character images, plus AI video and AI music/SFX. That covers most asset types, so AI is a major part of what ships. The human-written script and small catalog (2 games, none in the last year) argue against mass-produced volume. Against: Story and script are human-written, and the developer has only two games with no rapid release cadence, so this is not a volume-release pattern. |
