Decision comparison
| Verified point | What it means |
|---|---|
| PC is explicitly identified as Steam in Natsume announcements. | Use this as a firm decision input. |
| No PC system requirements, Steam Deck status, input details, or download size are published in the cited sources. | Recheck the live listing before purchase. |
| Console announcement does not prove physical stock; the current physical program names three platforms. | Do not extend this point into an unsupported performance or feature claim. |
How to use this page
Use this comparison to decide between a physical-copy priority and waiting for PC specifications.
This URL keeps one decision or gameplay purpose. When verified information changes, the existing page will be updated rather than spawning a competing near-duplicate.
Evidence boundary
Not yet confirmed: exact unlock requirements, numerical values, platform-specific technical behavior, and launch-day route details are not added unless Natsume or reproducible gameplay evidence supports them.
