Launch announcement snapshot for new players
The July 23 launch notice recorded a Redraw Gacha that lets a player choose one highest-rarity talent, a 15-day sequence adding 25 songs, and launch rewards tied to the 1.5 million pre-registration milestone. Treat these as a dated launch-announcement snapshot: availability and claim periods must be checked in the current in-game notice.
- The pre-registration reward list included 2,500 Diamonds, one ★4-or-higher ticket, three Music Disks, two Memory sets, accessories for 54 talents and five invitation tickets.
- The launch notice also described a login bonus equivalent to ten gacha pulls.
- This guide does not infer current banner rates, reroll value or whether any launch reward remains claimable.
Steam minimum requirements
The Steam listing currently requires Windows 11 64-bit, 8 GB RAM and 50 GB available storage. It lists Ryzen 3 2200G or Core i3-8100 class CPUs and Radeon RX 470 or GeForce GTX 970 class GPUs as the minimum configuration.
- Recommended CPU: Ryzen 5 3500 or Core i5-9400 class
- Recommended GPU: Radeon RX 580 or GeForce GTX 1060 class
- The store notes that supported devices and availability may vary.
Troubleshooting boundary
If a store reports an unsupported device or region, verify the official listing and current requirements first. This guide cannot bypass store availability, account restrictions, platform policy or a missing hardware feature. Use the official site's inquiry route for account-specific support.
