Ha! It's a bit poorly named, but what the mod actually does is edit out most of the anime reaction sounds in the cutscenes. It's surprisingly subtle - there are still plenty, but they're placed where it makes sense instead of characters exclaiming with every slight movement they make.

The mod page has a comparison video with the base game that shows what I mean, but if the noises didn't bother you then more power to you. Just be careful - I hear they can be contagious.
