Hey Hunter. I conversed with two of the other admins/mods. Both Sayomi Hayashi and Sweet Dreams agree with me that it is too Over-Powered and highly unrealistic (though, the entire show is unrealistic XD)
But the idea of having so much steel armor, and having two parts be made of Kairouseki is simply outrageous. Sweet Dreams said you were considering doing only the knuckles and leg braces, I believe this will make a bit more sense. Plus, this way, he won't be so weighed down by so much armor. I am a little reluctant to let him have sea stone knuckles, but if it's only one thing, and since he used to be with the Marines, I suppose I can let it slide.
