Minimum requirements

• At least 3.5GB (3500MB) of memory/RAM

• 4.5GB of available storage

• Android 6.0+ (Preferably 7.0 or greater for Obtainium support)

• If you are using an emulator, only Bluestacks 10 and MuMu 6 have been confirmed to work. LDPlayer and Nox do not work! MuMu 12 does not work!

1. If you have the Japanese version installed already, uninstall it. If you're using an emulator, you can instead use the multi-instance feature.

2. Download the English patched apk:
   ENG for 11.4.52 (2024/12/10)

   Download from MEGA Add to Obtainium
   You can get automatic updates using Obtainium. No more checking this page every time!

3. Install and run

4. Wait for extra data to download

5. After extra data downloads, the game will show a pop-up in Japanese (which says to restart the game). This is normal. Restart the game and the next pop-up should be in English.

6. If you can see badly spelled English text saying there is a roughly 2000MB update, congratulations! The patch is working. Onto the next step...

7. The main updater can take anywhere from 30 minutes to 2 hours. This is also normal, as it has to download the data from Japan.

8. If you can see the title screen with english text in the top right, you did it. Now you can play it in English! Make sure to link your account so you don’t lose your progress.

1. Download and install the latest version of PlayCover

2. Download the Guns Girl Z English Patched IPA (available in the "iOS & iPad OS" tab).

3. Install and play!

ENG for 11.4.6 (2025/02/06)

Before we continue, jailbreaking your device is the easiest way to get GGZ working in English. You don't have to jailbreak, but it will take much longer. And if you can't jailbreak... Well... Good luck.

There are currently jailbreaks for iOS up to 17.0.0 (if you consider roothide bootstrap a jailbreak). You can head to ios.cfw.guide on how to jailbreak. checkra1n and palera1n variants are recommended. The Taurine jailbreak does not work correctly with GGZ EN, do not use it.

Installing for iOS 14 - 17.0.0

1. Install TrollStore. If you are jailbroken, you can use TrollHelper from Sileo. Otherwise follow the guide on the trollstore webpage.
2. Download the Guns Girl Z English Patched IPA linked above.
3. Install it using TrollStore. It is normal for it to take up to 10 minutes, this is a very large IPA.
4. Now you have to enable JIT or it will crash immediately. The easiest way is to jailbreak your device. If you don't want to do that, continue below...

Enabling JIT without Jailbreak (14-17)

1. Install WireGuard from the App Store.
2. Download and install Jitterbug using TrollStore. (Select the .ipa file if you're confused)
3. If your device does not have a passcode, you must add one for Jitterbug to function.
4. Download and extract jitterbugpair for your PC. Connect your apple device using USB. On the device, trust the computer. Run jitterbugpair.
5. It will generate a pairing file. You need to copy this to your device so Jitterbug can use it. If you're jailbroken, you can use sftp in WinSCP (username is mobile, password is alpine), if not, copy it using iTunes or Google Drive or something.
6. Import the pairing file.
7. On the device, download the developer disk image for the iOS version you're using and import it into Jitterbug.
8. Now you can FINALLY launch GGZ with JIT without a jailbreak. Or you could have just jailbroken the device and saved yourself a bunch of time.
9. It is normal for GGZ to freeze on start for 1-2 minutes when launching it with Jitterbug. Be patient, it is consequence of apple's restrictions with JIT.

Installing for iOS 17.0.1+

1. Install SideStore.
2. Download from the MEGA link above and install it using SideStore.
3. Next we have to enable JIT or it will crash immediately. You should already have a jitterbugpair file from installing SideStore, so upload it to JITStreamer-EB.
4. Copy the new configuration to your iOS device, then install the JITStreamer-EB shortcut to your device.
5. Launch GGZ with the shortcut. It is normal for GGZ to freeze on start for 1-2 minutes when launching it. Be patient, it is consequence of apple's restrictions with JIT

If the app is crashing immediately on startup, you don't have JIT enabled. Jailbreak your device or launch with JIT using the tutorials above.

Houkai Gakuen 2 is available on Google Play in most asian regions. If you live in or near Asia, try checking there first.

Japanese app from QooApp

1. Download GGZ using QooApp. It will make you install QooApp…

2. Slide the other login methods right until you see “Guest”

3. Press back button on your phone when it asks for the phone number

4. Press back when the ad pops up

5. Search Guns Girl Z and pick the Japanese result

6. Install it

7. Congratulations, you did it. Now link your account so you don’t lose your progress.

Japanese app from the Google Play Store

This method is very difficult, but it's the only way to have in-app purchases. Expect it to take an hour because you have to fight through a maze of shitty options, mess with your payment profile, or god forbid the option to add a PayPal account doesn't work.

Google changes their options every year, so you have to search up the latest and greatest method every time. Good luck.

It is also possible to use a Google account without any payment methods attached, although very tedious.

To use an existing Google account:

1. Use a VPN in the Japan region. This is VERY IMPORTANT, DON'T FORGET IT!
2. Link a payment method. It will make your account a US one for some reason.
3. On a desktop, go to https://payments.google.com, navigate to the settings tab, and you'll see a US payment profile.
4. Click the edit button for Country/Region, it will tell you to make a new one.
5. Select Japan (duh), enter in your name, use a Fake Address Generator for your info
6. Now you should have two payment profiles. Select the US one and delete it.
7. On your phone, wipe the app data for the Google Play store.
8. Make sure your VPN is still enabled and set to Japan.
9. Open the Google Play store, switch to the account you just linked. Check Settings -> General -> Account and device preferences. If everything went well it will show Japan as the region.
10. Adding a PayPal within the Google Play app will show an error (probably because PayPal isn't supposed to be valid in Japan), so you need to add it on the website at https://play.google.com/store/paymentmethods. Alternatively you may purchase Japanese Google Play gift cards or use a credit card that allows international transactions.
11. Many credit/debit card companies charge a cheaper transaction rate than PayPal! It's worth looking into if you make many purchases.

Finally, search 崩壊学園 on the Google Play store or Click here, then click install.

You only have to use the VPN for installing the app, updates and in-app purchases will function without it.

Quick Setup

1. Download and install the latest version of PlayCover

2. Download 崩壊学園 from decrypt.day or ARMConverter.

3. Install and play!

If decrypt.day or ARMConverter doesn't have it...

If neither are up to date, you can dump it from your own device using TrollStore or request a dump in Foxgirl.

Japanese app on iOS

Luckily, iOS does not have IP-based region lock, just account based. This means you can download the app straight from the app store. However, there are some ceveats:

• You will have to make a Japanese iTunes account. Since iOS allows multiple iTunes accounts on the same device now, this shouldn’t be much of an issue.

• You obviously have to play it in Japanese with no instant translation apps.

• You likely will have to purchase a Japanese iTunes card for in-app purchases. You may get lucky and be able to use your regular credit card (Many credit card companies charge an additional fee for international purchases or will just block it unless you call them), but I wouldn’t count on it working.

Since Apple likes to change how to make an account all the time and I don’t own an iOS device, you’ll just have to pick the most relevant result in a search engine. Here’s a hyperlink to make it easy for you: “create a Japanese app store account”.

Afterwards, simply search 崩壊学園 on the App Store or Click here.
