/me copies and pastes.

Also, many people think depriving Erza of her tactile senses will backfire on Kyouka. Why? Removing tactile senses means she cannot feel an object against her body, it doesn't mean she can't feel the pain. The confusion here might be that people might be considering this too scientifically. It has never been stated how Kyouka's curse works. It just says that her sensations are enhanced, not that it affects the nerves, etc. Which means that she can't feel an object touching her, but does feel the pain the impact causes. The basic problem here is that nerves conduct all the sensations, so most people assume, understandably, that no tactile sense means she can also feel no pain. Please realize that this is magic, it doesn't have to make scientific sense, and that Kyouka is not stupid. Also, the curse might affect the brain receptors rather than the nerves. Considering the number of senses and the different ways they work, it would be a much better way for the curse to work, more ... unifying? Think CIP, just exchange the tactile sense with the sensation of pain.
