[Notice Regarding the Termination of Account Linking Function Using "Yostar Account"]
On Wednesday, August 20, 2025, during maintenance, the account linking function using "Yostar Account (*1)" and "Apple Account" will be terminated.
After the termination of this function, data transfer will no longer be possible, even if data linking was previously performed with the respective accounts.
If you are currently using only a "Yostar Account" or "Apple Account" for linking, we kindly ask you to use account linking with a "Yostar ID" or issue a "Linking Code (*2)" for game data transfer.
Additionally, at the "Yostar ID Center," you can check the linked email address or the game accounts currently linked, so please make use of it.

Moving forward, the only available linking methods will be "Yostar ID" or "Linking Code."
To prevent the loss of game data, we kindly request that you link your account with a "Yostar ID" or issue a "Linking Code."
*1 "Yostar Account" refers to the "Yostar Linking (Email Address Linking)" that is currently available for linking from the in-game menu as of August 2025.
*2 When transferring data using a "Linking Code," a "Game User ID" is required, so please make sure to note it down when issuing the "Linking Code." (The "Game User ID" can be confirmed when issuing the "Linking Code.")
