July 18, 201015 yr In KHII Mickey says its because his eyes couldnt lie. And in days it shows that pretty much by covering his eyes, he could fool himself and others about his darkness. And for fighting i guess it's cuz he can catch people's scents.
July 18, 201015 yr maybe he does that thing bats and some blind people do, or maybe the blindfold isn't that thick so he can sorta see
why is it that riku has a blind fold on i never knew why he had it
