It's a good question! So it is actually a ninjutsu not genjutsu. It is a bloodline specific ability it is actually one of the more powerful custom bloodlines in the game. It's specifically it's one that hakuro developed himself. Fun fact he actually developed it because he didn't like the sharingan. Or more specifically he didn't like how the sharingan was supposed to be called like a mirror eye and it had absolutely nothing to do with mirrors. So what this does is it creates or what this eye specializes in is it creates copies of what can be seen. So against again jutsu it's almost useless because genjutsu doesn't work you have to see it to be able to protect it or to be able to copy it for reflect it.<br/><br/>So in short bloodline ability, can only reflect visible objects. Note if someone is invisible or jutsu is invisible it will still copy and reflect whatever is there just no one would be able to see it except the original Castor of the jutsu. If it is an aim to jutsu like water dragon where you have to aim where the dragon is going, it would create a mirror clone of the water dragon but if it's invisible hakura wouldn't be able to guide it because he can't see it to direct it so it definitely comes with its own downsides too.<br/><br/>So in this case what the clones that he made are is they are mirroring your guys's basic appearance and basic stats however they cannot use skills that you have. However the exception being is once again things that are visible. Iori's sword and her sharingan. Because both of those are visible. However the sharingan on the clone is useless because it's controlled by the AI anyways so it doesn't do anything to boost the stats of the clone or anything else. It's just a visible representation of what your character is doing. Once again a mirror
