Re-rolling is the action of resetting your game state in order to get a better starting line-up of playable characters. In this game you can do two 10-pulls on the gacha banners and exchange a single 4 star ticket for a guaranteed 4 star unit.

If you use an emulator when you're finished rerolling you can Data Transfer your account to your phone

Preparations

Make sure you have a VPN to a Japanese server and make sure you setup your device depending on how you're planning to re-roll.

Tutorial on using VPN for Android and iOS

OpenVPN:

  • OpenVPN for Android(by Arne Schwabe) and VPN Servers for OpenVPN(By DSchmidt)
  • Make a Profile in OpenVPN, then open VPN servers, pick a jp server and hit connect

Other (paid) VPN choices: Nord, OpenVPN, ProtonVPN, UrbanVPN and Tunnelbear​​​​​​

Download the game by either going to the JP Google play store or by downloading the APK from QooApp.

Nox

Make sure your emulator is using Android 7.​​​​​​

Re-rolling

For iOS and rooted Android devices

If you are using iOS, I recommend downloading an Android Emulator on your computer, reroll and then transfer the account. It may be advisable to not do the batch download until after you finished re-rolling.

  • Skip the story and tutorial
  • Do the first 10-pull
  • Enter name and retrieve items from present box
  • Do another 10-pull and use the 4 star ticket

In order to re-roll: uninstall and reinstall the game.

For rooted Android devices and emulators

Rerolling on a rooted phone is much quicker as it can bypass the repetitive downloads normally required when uninstalling and reinstalling an app. Please note that you will need a Root File Manager (such as Root Browser) installed on your phone or emulator (Nox App Player has one pre-installed). In addition, I will only be describing how to do this process on an Android rooted phone/emulator.

  • Install the game
  • Install a Root File Manager (if you haven’t already)
  • Start the game and skip the story and tutorial
  • Do the first 10-pull
  • Enter name and retrieve items from present box
  • Do another 10-pull and use the 4 star ticket
  • If successful in getting a desired character, continue the game as normal
  • If not, open your Root File Manager and go to:  
    • Open Android file - Data and Obb
    • Rename the file " jp.co.sumzap.pj00071 " by adding 7 behind it
    • Delete the game's data
    • Rename the file back to it's original name
  • Restart the game and repeat the process till you get a desired character
