Sakazuki

Sakazuki,[7] formerly known by his admiral alias Akainu,[1] is the current fleet admiral of the Marines, succeeding the previous fleet admiral, Sengoku.[2] During the first half of the series, he was one of the three admirals,[3] and the last one to be fully revealed.[8] One of his first decisions was to relocate the Marine Headquarters into the New World in preparation for the New Pirate Age.[9] In the manga, he was first mentioned by Nico Robin during the initial encounter with Aokiji.[3] In the anime, he was mentioned earlier by Vice Admiral Jonathan during the anime-only G-8 Arc, which aired after Akainu had been revealed in the manga.[8] Sakazuki is perhaps the most strident follower of Absolute Justice in the entire series, to the point where his extremism prompted his fellow admiral Aokiji to oppose his promotion to fleet admiral and resign from the Marines after this effort failed.[2] Because of his actions, Sakazuki is one of the main antagonists of the Marineford Arc and after his promotion, he became one of the central antagonists of the series.
