My question is about busoshoku haki or coat of arms as people like to call it. Until the last episode I thought haki was something that required intensive training to master. But in the last episode
For those who haven't watched spoilers:
Sabo was shown wielding busoshoku against a small army at 17.
Now I only started reading the manga in the zou arc so I'm not sure if this is filler or cannon but is it safe to assume then that some people just have an aptitude for mastering buso quickly? I mean only a small percentage of people are capable of using haoshoku so it seems like it makes sense.
But it took Luffy two years to perfect it and I'm not even sure if Ace ever learned it. Does anyone have any feedback on this?
