If Enter Coupon is unavailable, complete the opening progression and reach the Main Lobby before checking Account Management again. If a coupon fails, verify its exact spelling, redemption window, service region, and whether the account already claimed it.
StarSavior can announce coupons before their redemption period begins. Do not treat a scheduled coupon as Active until its official start window has opened, and do not restore an expired coupon only because an older list still labels it as working.
Successful rewards are delivered through the in-game Mail. Claim delivered rewards within their storage period instead of leaving them 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. Broadcast campaigns can include immediately redeemable coupons as well as coupons with a scheduled activation window.
Use the Active Codes table for coupons that can be redeemed now. A coupon with a future official activation time should only move into the Active table after its redemption window begins.
Trailer, Screenshots & Media
The existing StarSavior gallery and official animation PV remain relevant to the game and its coupon post. No media replacement is required for this repair.
StarSavior Codes FAQ
6 questionsCommon questions about redeeming StarSavior codes.
From the Main Lobby, open Menu, select Game Settings, open Account Management, and choose Enter Coupon. Submit the coupon on the account that should receive the reward, then collect it from the in-game Mail.
Public coupons are normally limited to one redemption per account during their availability period. Another eligible account can redeem the same public coupon independently while its redemption conditions remain valid.
The redemption window may have ended, the coupon may belong to another service region, or the account may already have claimed it. Check the associated official notice before trying the code again.
Studiobside can distribute coupons through official news notices, Developer Talk broadcasts, update programs, anniversary showcases, seasonal events, X posts, and YouTube broadcasts. Some campaigns announce a coupon before the time when redemption actually begins.
Successful coupon rewards are sent to the in-game Mail rather than added silently to every inventory screen. Check the Mail after redemption and claim the reward within the storage period stated by the game.
No. A coupon released only for another service region should not be treated as a Global coupon unless Studiobside explicitly makes it available to the Global service. Always follow the service scope of the associated official announcement.
