What we claim. The written analysis on this site — the ending breakdowns, the deduction tables, the gift timing chart, the walkthrough structure and the achievement commentary — is our own work. You may quote short excerpts with attribution and a link. Republishing whole pages, or feeding them wholesale into another site, is not permitted.

Game imagery. Screenshots and official key art appear under a fair-use rationale: they illustrate specific mechanics in a guide and are not sold, licensed or used as branding for this site. Where an image is taken from the official Steam page, that is stated in context. If a rights holder prefers an image be removed, we will remove it on request.

Not official. This wiki is not affiliated with, endorsed by, or sponsored by Tohakusha Inc., CIRCLE LINE GAMES or Valve. The name is used descriptively to identify the subject of the guides.

Takedown and corrections. Rights holders with a concern about any asset or claim on this site can contact the site operator with the URL and the specific material in question. Verified requests are actioned promptly, and factual corrections are published with a dated note rather than edited silently.
