Riku's blindfold

[Allister Rose]

the blindfold ws so that riku wouldnt use the darkness of XH within his heart.

if you think about it, it's like he uses the blindfold to hold back, so when he wants to go full strength he actually uses his sight

i always thought riku sense like his other senses heighten since he was wearing a blindfold thats what i thought
