Let's see. So, first things first, for some reason, it doesn't work. Like, at all. Sure, it changes the "golden wind" in the title of the first episode to "gold experience" (and I'm not even sure if that's a change, it might just be normal crunchyroll), but in the episode itself, gold experience is still called golden wind (for some reason). This extension, for some reason, doesn't work. I suggest that the creator tries to fix it somehow, and tries to understand what's causing the problem.

Half the time it doesn't change anything, Aerosmith is still Li'l Bomber, Little Feet is still Tiny Feet, so on and so forth
