Using a Rename Card
To change your nickname, use a 'Rename Card' item from your inventory. This is the primary method for updating your in-game name at any time.

Obtaining Your First Rename Card
Complete the 'Growth Mission' when you reach Level 10 to receive your first free 'Rename Card'. You will earn one card per Growth Mission completion as you progress.

Finding and Managing Rename Cards
Access your Rename Cards through Shop → Cards tab in the main menu. Each card can be used only once per day, so plan your name change accordingly.

Important Limitations
You can only change your nickname once per day using a Rename Card. Ensure you are satisfied with your chosen name before confirming the change, as frequent changes are restricted by this daily limit.
