What I like most of this fight was the concept of follow up, not just one strike after another, but strikes that serve for the next attack, attacks with the sole purpose of making damn sure your opponent is DOWN.
Also yes he used kure techniques after they both had removal.
And I still believe that Cosmo won't come back, let's be honest, he did his best, there's nothing left for him to fight for.
This was a bloody fight but looking at the tanks that comes next, I expect the worse now XD
