need help with files from Love Live After School Activity (.pac files)

[RX-F90]

I used the onepiece_arc script to extract the contents of a .pac file contained in the game since that was the header that was expected from quickbms.
The extraction of the files were successful, but the resulting contents are generic and unusable.

I'm fairly new to using quickbms, but my main question is did the script work as intended or is there additional research that needs to be done to somehow resolve the file types contained in the archive?

The original pac file I am working with can be found below:
