Sakazuki, formerly known by his Admiral alias Akainu, is the current Fleet Admiral of the Marines, succeeding the previous Fleet Admiral, Sengoku. During the first half of the series, he was one of the three Admirals, and was the last one out of the three to debut. Upon becoming the Fleet Admiral, one of Sakazuki's first decisions was to relocate Marine Headquarters into the New World in preparation for the New Pirate Age.
