Upon first launching Dokkan Battle, you'll be prompted to download game data. This can be quite large, so ensure you're on a stable Wi-Fi connection. Once downloaded, you'll go through a brief tutorial that introduces the basic battle system. After the tutorial, it's highly recommended to link your account immediately. Go to Menu > Data Transfer > Link with Google/Facebook. This safeguards your progress and allows you to recover your account if you switch devices or lose your phone. Losing an unlinked account means losing all your progress, including rare characters and items, so don't skip this vital step!
