both standard coa and advanced coa are ways to utilize ryuo(aura) surrounding the body. it's literally the same concept as Ki, Chi etc.
even Nen is based on this concept iirc
remember when Hyo said that he'll teach Luffy utilize unnecessary ryuo surrounding his body to create invisible armor?
ryuo is an aura, it's not advanced armament ffs
jesus christ people... ryuo is wano name for haki. it's like mantra in skypiea.
literally everyone in the world has haki but not everyone can utilize it.
