Reroll

Currently, the only way to reroll on phone is to switch servers. As server progress are separate, you will start over from tutorial again.

For emulator, It is done by installing the game on an instance (Fresh instance preferably) Then cloning it before signing in as guest, and use the clone to reroll. If not satisfied then delete the clone, and reclone the original one.

It is worth noting that you can also reroll by using another dummy twitter account, although it is not recommended.
