It turns out SAO Fatal Bullet for Switch uses UE4 v5 (4.20) custom build with Oodle fix and pak uses Oodle compression, which is not unpackable without access to Oodle SDK with any unrealpak (but you can get file list with compressesion sizes and offsets) + QuickBMS UE4 script doesn't support v5 oodle. So if someone has a way to unpack it, it would be great.

Edit: UEViewer can only partially extract files, nothing that I want.

I wonder why Bamco didn’t release fatal bullet in America, not feeling like importing, reading some reviews saying it’s not that great.

OK, I found out how to unpack files.
This is modified script for QuickBMS.
It turns out script has line that is blocking oodle decompression if pak file is not version 6 or higher. Changing it to 5 enables unpacking.

Code:
        if VERSION >= 6
            comtype oodle
to
Code:
        if VERSION >= 5
            comtype oodle
