The verified update
No. The first trailer confirms showcased game features, but it does not establish the content, limits, save rules, or platforms of a demo build.
The evidence was checked against Natsume first-trailer announcement and is current to 2026-07-31. The date attached to the underlying source is 2026-06-18.
What the source establishes
- Natsume calls the June 18 asset the first trailer
- no trial duration is supplied
- no demo content list accompanies it.
Why it matters
Use the trailer for feature evidence and wait for a verified trial listing before writing a demo walkthrough.
That distinction helps players make a release, platform, route, story, or purchase decision using the narrow fact actually supported by the source.
The remaining boundary
Marketing footage may come from a different build and cannot be converted into demo instructions.
Any later change should be dated and linked to a new first-party notice rather than silently overwriting the historical source.
