Malphegor
A little information about the beginning of the chapter “ There are two known different types of swordsmen, the Strong Blade (豪剣, Gōken?, literally meaning "Strong Sword") type swordsmen which emphasis strength and the Gentle Blade (柔剣, Jūken?, literally meaning "Gentle Sword") type swordsmen which emphasis speed.[4] Dracule "Hawk-Eye" Mihawk, the greatest swordsman in the world uses swordsmanship that is a perfect balance between the Strong and Gentle Blade styles, being able to slice through battleships with supreme power and deflect bullets with graceful speed.” from one piece wiki
