Top Level Settings (各種設定)

The Top Level Settings (各種設定) covers the basic settings of the game accessed on the Start Screen.

ユーザーID is your User ID, and if you want people to find your account, the 9 digit number is written at the top. This is also found in other parts of the game.

データ引き継ぎ is if you want to switch accounts. You are limited to 10 changes of account per month. This essentially limits the number of accounts to 1 per device. If you switch accounts to one that is on another device, you will not be able to use the account on the previous device. If you open the previous device, you will have the option to start over or enter another account. This can only be accessed here.

グラッフィック設定 (graphic settings): controls the graphics. See graphics in the menu section for full explanation.

利用規約 (usage regulations) takes you to a website. It is essentially the terms and conditions, but also contains some directions on using the app. This is entirely in Japanese except for the privacy statement.

お問い合わせ is the Frequently Asked Questions. This also sends you to a link completely in Japanese.
