Talk:Busoshoku Haki

Armament:Hardening is not a general technique. Luffy only gave his black haki a name to signify that his rubbery haki (as stated by Doffy) is vulcanized. Because in Japanese vulcanized rubber is simply called hard rubber (obviously because in Japan they don't share the cultural context of the Roman pantheon). It would be more informative to say the technique is called Armament: Vulcanization.

The black haki is simply a visible cue to the presence of armament haki now that our viewpoint characters and we the audience know what's going on, where pre-skip they didn't. We know this because, well, why the hell would every haki user suddenly start using this other technique that renders "normal" haki use obsolete; they didn't, and the black haki is just the normal invisible force field. 66.244.204.211 04:42, July 29, 2018 (UTC)
