The verified update
No. Because Natsume has not announced a public demo, it has not published a demo file size for any platform.
This briefing isolates one part of the public record so that a player can act on the confirmed detail without mistaking a broad trailer, preorder listing, or product page for a complete specification.
What the source establishes
- The official announcements contain no demo specification.
- No PC or console demo download page is linked by Natsume.
- The full game’s platform-specific file sizes are also not stated in the press releases.
Why it matters now
This status prevents fabricated storage recommendations while leaving room to add exact numbers when platform listings expose them.
For editorial tracking, this topic should be reviewed again when Natsume publishes another game-specific release, when a verified platform store exposes new metadata, or when launch-day testing can answer the remaining operational question.
What this update does not establish
Any download-size claim should identify the exact verified storefront and build; a trailer file size is not a game-demo size.
No unannounced feature, value, route, schedule, performance target, item table, or story outcome has been inferred. The distinction is important because the game is still unreleased.
