Charlotte Linlin had learned Tekkai the moment she got her hands on it. Then, in less than half a year, she had trained it to a level that was likely unprecedented.
Combined with the fact that she should already have been the strongest in the world, and now possessed further enhanced, extraordinarily powerful Armament Haki, her physical defense could practically be called truly indestructible. Katakuri even suspected that she could now use her body to withstand the ultimate attacks of other top-tier powerhouses head-on.

Not only did this not hinder movement, but its principles could also be directly applied to Armament Haki, making her punches and kicks just as astonishingly powerful as her already formidable defense.
Now, even Katakuri's hardened mochi enhanced with Armament Haki could be casually shattered by Charlotte Linlin. Her fists and feet, clearly made of nothing but flesh and bone, were actually sharper than Supreme Grade Swords!
