User blog comment:Ero-cook/Why didn't Ace get to learn Busoshoku Haki?/@comment-3119203-20111106200023

I was wonderin the same thing Ero-cook, after his defeat by Whitebeard and his draw against Jinbe, he obviously wasn't overconfident in his DF (until he fought BB that is). With all of the haki experts on the crew you think he would have learned something right? And everyone says it takes a long time, but Luffy learned it in two years, and even then he had time to refine his Gears and learn some new techniques. Rayleigh even taught Luffy the basics in one and a half years. The simplest explanation isnt that he was cocky, but that he never needed to use haki. Logias? No problem, he is a logia himself right?
