Redemption Guide
3 platformsStarSavior uses an in-game coupon menu. The official A Study in Gray notice confirms the route from the Main Lobby through Game Settings and Account Management.
Menu in the upper-right corner.Game Settings.Account Management.Enter Coupon.Confirm.Mail and claim the delivered reward.Menu in the upper-right corner.Game Settings.Account Management.Enter Coupon.Confirm.Mail and collect the reward.Menu in the upper-right corner.Game Settings.Account Management.Enter Coupon.Confirm.Mail and collect the reward.Code Rules & Troubleshooting
If Enter Coupon is missing, complete the opening tutorial and reach the Main Lobby before checking Account Management again.
If a coupon fails, confirm that the exact redemption window is still open, that the account belongs to the correct service region, and that the same account has not already claimed the coupon.
Enter the string exactly as it appears in the official notice and remove accidental spaces before confirming it. Do not rely on an old third-party Active Codes list when an official expiration date is already available.
After successful redemption, check the in-game Mail. Coupon reward mail should be claimed within its storage period rather than left uncollected.
New Code Announcements
Studiobside distributes StarSavior coupons through official news notices, Developer Talk broadcasts, update programs, anniversary showcases, seasonal events, the official X account, and the official YouTube channel.
The newest confirmed coupon remains READY26AUTUMNGIFT. The official news index contains no newer coupon announcement through September 7, 2026. The next Developer Talk is scheduled for September 10, so any code revealed during that future broadcast should be treated as a new update rather than added before it is actually announced.
Trailer, Screenshots & Media
The existing StarSavior gallery and official animation PV remain suitable for the post. The September 10 A Study in Gray Developer Talk has not yet occurred, so there is no completed newer broadcast video that needs to replace the current media in this September 7 fix.
