I thought as much, as it did seem odd. To rule out further influences I've simply re-extracted '[ScrewThisNoise] AI-Shoujo BetterRepack R15.7z' into a clean directory, and launched the game from there. (therefore, removing the possibility of user data, changes or settings causing issues)
With that said, since I was running on defaults (so, no graphicsmod; by default) naturally SSS would is disabled again, so I looked for the other card you mentioned, which is still present. I've added a new screenshot that is showing a zipmod error, along with how the game loaded that (non-SSS) character.
I've also attached a screenshot of the archive and the files within the 'cunihinx' directory. (This is the archive simply loaded, but matches the extracted game.)
I've attached the one I used for this post below.
