By this point in her life, Tifa has gotten used to metal on limbs or in place of them. Vincent has golden metal on his feet and an arm made of the same. Cloud has a metal pauldron on his shoulder. Yuffie has metal on her arm guard. And Cait Sith is a robotic cat riding a stuffed moogle. Tifa doesn't even bat an eye at the man who speaks up.
