On another random note. Someone please explain to me how some of these rokoushiki techniques are not haki oriented? I know it's already established as being its own thing but come on.
How can Lucci and stucy project shigan to fire like an actual bullet from a distance?
How does geppo even work? You are literally bouncing on air. Wouldn't that be a concept of ryou? Projecting your haki to solidify a surface mid air to jump on it like a platform? How else does geppo even work. You are literally hoping on nothingness.
And tekkai is obvious a weaker version of Armament more so focused on tightening your muscles to be hard as armor rather than shrouding your self in invisible armour.
Amd tempest kick? Kicking so hard that you slice the actual air? Making a air slash? That to me only makes sense if one hardens their body to confine it making it sharp enough to cut through the air.
