Inheritance (引継ぎ) or better known as Account Transfer allow teachers to transfer their account from one device to another.
The following is a guide for JP.
Process[]
In order to transfer, teachers will need both their Game User ID and Linkage Code (and a device that they planned to transfer to). Teachers should take note and remember both of this information.
Generating a Code[]
Unlike other gacha games, teachers cannot create a password but rather, they will need to generate a random code.

There will be two fields on the Linkage Code. The top fields will be fill with the "Game User ID (ゲームユーザーID)" with the left button being "Copy (コピー)" while underneath will be teacher's "Linkage Code (連携コード)" which will be blank unless generated. Click on the blue button "Code Generate (コード生成)" beside it to generate a random code. Teachers can generate as many as they one but only the newest one will be set.
Take a note or screenshot to remember both information.
The author is unsure if the code generated will expire so please double check under Device Linkage Code before transferring.
