We got nice action panels, really fluid and satisfying to see luffy deal some punches. But I still hope that kaido will dismiss this as minor damage.
Although we got a visual indicator for CoC attacks, the mix with the new ryou coa skill is a bad idea. We cannot tell who is using wich skill in a fight if all we got to identify is space and some lighting. We will have to guess based on who have coc, but what if the haki battery is empty?
And this is a recurring problem with haki, we can't identify CoO, the character must say he is using the skill, or sometimes we have a panel with the future. The later is better for me, although the use is very restrict and cannot be applied to every case. Something more simple like the spider sense could be used, but i'm not sure if this is a good idea.
CoA is even worse, this is an armor. We have to be able to visualize this, and this idea of invisible armor is the worst of all. And the only good explanation for this is a retcon, we have so many characters who use attacks and we don't know if they are using CoA or not. The black indicator is also a bad one, no one can use black gloves/weapons/clothes in a black and white manga. The dragon ball approach with ki would be better, something that is not directly in the character, like the lightning effect for CoC.
