Eternal Palace Sakura ships with Steam achievements, along with Steam Cloud saves and family sharing. The achievement list was not yet fully mirrored by the community at the time of writing, so this page is structured to be filled in rather than padded with guesses.
Achievement queries are the most reliable long-tail traffic a game wiki can capture. A player who just unlocked something obscure and wants to know what the unlock condition was will search for the achievement by name, land on a page that answers it, and stay. With fifty-plus fighting arts and twenty-plus enemy types in the game, the achievement list is likely to be long — which means a long list of queries that currently have no good answer anywhere.
The Steam client is the authoritative source: open your Steam profile, open the game's achievement list, and every name and description is right there. The Steam Community guides and discussions for the game are the other good source — the community tends to transcribe the list within a few days of a launch. If you send it over, this page becomes a full reference rather than a stub.
The developer ran a CAMPFIRE "Launch Support Project" starting September 30, 2026, Japan-region only, which offered Steam keys for early access, campaign-exclusive merchandise, and a name listing in the end credits. If you are reading this before the credits roll, that is worth a look — the credits list is a small, finite, and genuinely exclusive reward.
