Decompression Help

[startropicz]

i've decrypted and extracted the contents from Saiki Kusuo no Sainan - Shijou Saidai no Sainan (the The Disastrous Life of Saiki K. 3DS game) but i've hit a wall. i'm trying to get the character models but i can't tell exactly where they are? nor do i have any idea how to unpack the PAC files. in hex editors, i can see the game calling on the models i'm looking for, which are in the format i'd expect them to be in;

but everything that's in the decrypted folders (except the music) is in .PAC format. i've dealt with this before when ripping models from Persona Q, but all I had to do there was delete a signature at the beginning of the files' hex stuff and then i could put it into Ohana3DS as a PAC but it'd get recognized as a model (complete with animations, too). i'm not good with programming or coding or anything at all, ctrtool is a nightmare that i can't even begin to comprehend.
if anyone knows anything to help, it would be appreciated. i saw an older forum post where someone was struggling similarly with the same game, but they found how to decompress the files, except they didn't explain what they did to decompress them. i'm at a loss, really TT
