Your Assault Lily Last Bullet account is not an email login: it is delivered as a transfer code, that is a transfer ID and a transfer password. You enter them on the title screen of the Japanese version of the game, and the account loads onto your phone. Here is how to do it without mistakes, and how to make the account yours afterwards.

What you receive

A transfer ID and a transfer password: together, they load the account onto your device.
The server: Japan. The game is the Japanese version, アサルトリリィ Last Bullet, and it works on Android and iOS, as shown on the Assault Lily Last Bullet starter account page.
An account where only the tutorial is done, so many login rewards are still waiting for you.

Log in step by step

Install アサルトリリィ Last Bullet from the Japanese App Store or Google Play, then open it.
On the title screen, tap サポート (Support) at the top right. Do not tap anywhere else on the title screen first, or the game starts a new account.
Choose データ引き継ぎ (Data Transfer).
Enter the transfer ID and the transfer password exactly as written in your order, and confirm.
Wait for the screen that says the transfer is complete, then go to the home screen.

Type the ID and the password by hand rather than pasting them: no space before or after. They are case-sensitive.

Secure the account right away

Set your own transfer password. On the home screen, open the menu at the top right and tap データ引き継ぎ. The guides say the password must be 8 to 20 half-width letters and numbers.
Write down the ID and your new password outside the phone, for example on paper or in a password manager. The ID is shown on the same screen.
Add a second backup if you want one. The same menu offers to link a social account; guides list Google and Apple among the options.

Android or iOS: what carries over

The transfer ID works between Android and iOS. Free Magi Jewels carry over to the other system, but paid Magi Jewels do not: they stay on the system where they were bought. If the Magi Jewels count looks wrong after the transfer, stop there and contact us before you play.

Common problems

An error when you confirm: in most cases, a space or a wrong character slipped in. Type both fields again by hand.
You landed in a new tutorial: the title screen was tapped before サポート. Close the game and start again from the title screen.
The app is not in your store: the game is a Japanese release. You need the Japanese App Store or Google Play to install it.

What our after-sales service covers

If the account does not match its description, or the transfer code does not work, email us within 48 hours of delivery: we send a replacement or refund your order. Tell us your device and the exact message shown by the game. Details in our FAQ.
