We recommend using the Link Data setting so that, in the unlikely event that the app is deleted, it is easy to continue playing the game.
If this link is set up, current game data can be transferred after reinstalling the app.
Linking with KONAMI ID also completes a Line Objective with an Exp. 10,000 Token as a reward.

To enable the Link Data setting, select the following:
