I hope everyone here get a chocolates

Recently i've been working to look any toaru index imaginary fest files with my phone unfortunately i've got a solution with using Bluestacks and rooted with bluestack tweakers.
Based the other post i've got game files inside data/data/com.square_enix.android_googleplay.index_if
I manage to get those files and try to opened with Asset Studio but it failed
Someone said that it is encrypted with simple 1-byte xor key
So the question is
Is there anyone know how to solve this encryption and also get a texture files from this games

Guess what? xor.key Changed with it! And it's cyclical! Sorry about my explanatory power.. For example: file a, byte 0x7-0xa is 00537b43, its first XOR key is 47, and file B, byte 0x7-0xa is 537b4385 (do you see it? The XOR key 47 is the last! File C, byte of 0x7-0xa is 7b43859a > >....... Cycle!

After further analysis, I guess that there are 1024 decryption schemes for the files, two of which are not encrypted or spam themselves (but you can delete them manually). They all have plaintext: unityfs, and one of the remaining 1022 is viewtopic.php?f=16&t=21917&p=171560&hil ... st#p171560 Use only one byte encryption，I only manually decrypted a few keys, which are only useful for a few files. I also decrypted the "b20e38b5" in the root directory, and found the details that seem to be the decryption scheme? I don't know the code. So I'm not sure.Looking at the installation package, I found that the company has another game I am playing:Nier Re[in]carnation，I have reason to believe that Nier uses the same encryption method。（Please forgive my grammar, it comes from the translation engine）

Can Nier re [in] carnation be unpacked?

Looks like it can be with this tool:
